SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
A. STRUCTURAL COMBINATIONS WITH CIRCUIT ELEMENTS:
Electric lamps and electric space discharge devices of any
type (including cathode-ray tubes) with or without a discharge control
device, combined with other circuit elements all of which (other
than a mere source of current and/or potential supply if
claimed) are structurally combined therewith to form a unitary device.
Such structurally combined circuit elements may be in either or
both the input or output circuit of a discharge device, or in neither
circuit, and may be used for any purpose. Such means appear in
this class (see Subclass References to the Current Class, below).
If any circuit element is not structurally combined as stated above,
the patent is treated as stated in the following sections. See the
sections F-4; and G; and H, especially.
B. STRUCTURAL COMBINATIONS WITH HEATING AND/OR COOLING
MEANS:
The subject matter of section A, combined with means for heating
and/or cooling the lamp or discharge device structure,
which heating and/or cooling means is either structurally
combined with the lamp or discharge device, or with an electrical
circuit element, or forms an electrical circuit element. All electrical
circuit elements (except a mere source of current and/or
potential supply, if claimed) which are not structurally combined
with the lamp or discharge device must be structurally combined with
the heating and/or cooling means; see Subclass References
to the Current Class, below. If any circuit element is not structurally
combined as stated in this and the preceding section (A), the patent
is treated as stated in the following sections (see section H-2-d
for other temperature-modifying combinations).
C. CATHODE-RAY TUBES:
Combined with an electric system for the supply and control
of current and/or potential thereto as the ultimate load
on the system. Sections A and B, above, deal with other special
cathode-ray tube systems in this class. Such means appear in this
class (315). See Subclass References to the Current Class, below.
D. LAMPS AND/OR DISCHARGE DEVICES AS SOLE LOAD DEVICES:
1. With an electric system for supplying current and/or potential
thereto. If there is any other type of electric load device, as
either the sole ultimate load device or in addition to the lamp
and/or discharge device load, the patent is in some other
appropriate class. The load may be constituted by one or more lamps
alone, by one or more discharge devices alone, or by any combination therebetween
subject to the limitations noted below in this section and in the
following sections. Discharge devices having a claimed output circuit
are in this class only in the special cases set forth in paragraphs
A, B, and F.
2. Where systems are provided with an impedance in the supply
circuit of the lamp or discharge device, and the sole function of
the impedance is to regulate current flow to the lamp or discharge
device, the impedance is not considered a load device.
3. Systems wherein an impedance is substituted in the circuit
when a lamp or discharge device is removed therefrom so that the
impedance provides a substitute load on the system are included
in this class, see Subclass References to the Current Class, below.
E. LAMPS:
With an electric system for supply and control of current and/or
potential thereto as the ultimate load on the system.
F. ELECTRIC SPACE DISCHARGE DEVICES:
1. Combined with an electric system for the supply and/or
control of current and/or potential supplied thereto, the
discharge device being the ultimate load in the system, where the
system of supply and/or control is to result as its sole
function in either or both: a. causing a discharge to take place
or b. mere regulation of the discharge.
2. In this type of system, the output circuit may be claimed
if it is claimed so broadly as to be in effect the mere completion
of the circuit so that a discharge may take place.
3. This type of system is included even though the type of
current flowing in the anode-cathode circuit is specified as being
different from the supply current (as, for example, d.c. and a.c.,
respectively, as in the mercury arc type of discharge device).
4. Due to differences in operating characteristics between:
a. gas or vapor discharge devices, and b. high vacuum discharge
devices. Systems limited to these two different types have been
treated differently, see sections G and H, below.
5. The preceding limitations cause exclusion from this class
of: a. The regulation and/or control of the current and/or
potential in a circuit by means of a discharge device, even though
no load device in the regulated and/or controlled circuit
is claimed, and the discharge device is under the terms of the claim
the ultimate load device; b. Those systems having one or more discharge
devices constituting the ultimate load on the system, where the system
includes means which limit the system to use for purposes other
than, or in addition to, section F, Electric Space Discharge Devices,
1 (a) or (b) above (e.g., to amplify, modulate, etc.).
G. GAS OR VAPOR DISCHARGE DEVICES:
1. combined with an electric system as defined in section
F are included in this class when the claims are restricted to discharge
devices of the gas or vapor type, and: a. where they are only principal
electrodes, b. where there are one or more discharge control electrodes
in addition to the principal electrodes which do not function to
retain control of the discharge after it is initiated to regulate
the same, c. where there is an electromagnetic discharge control
device (other than or in addition to electrodes as in (a) or (b)
even though it controls the discharge after it is initiated.
2. Where there is a discharge control electrode of any kind,
or a nonelectrode discharge control device other than electromagnetic,
and the system is so designed that the discharge control device
or electrode retains control of the discharge after it is initiated
to regulate the same (continuous control type), the patent is excluded
from this class.
3. Where the discharge device in the system is disclosed as
being of the gas or vapor type, but the claims are not so limited
(the device being claimed broadly as a discharge device), the patent
is not classified in this class, but in some other class appropriate
to the subject matter claimed, except in the particular instances
set forth in section H.
H. HIGH VACUUM-TYPE DISCHARGE DEVICES, AND GAS OR VAPOR-TYPE
DISCHARGE DEVICES CLAIMED BROADLY:
Combined with an electric system as defined in section F,
Electric Space Discharge Devices, above, are included in this class
only in the following particular situations (being in all other
instances excluded):
1. Structural combinations as defined in sections A and B,
above, with or without discharge control means;
2. Where the only electrodes claimed are the principal electrodes
(no discharge control device of any kind being claimed) and the
patent is classifiable in one of the following art areas: a. having
means to automatically substitute a second source of current and/or
potential supply, b. having means to automatically substitute a second
discharge device for an operating discharge device when it fails
to operate properly, c. having means to supply current to the cathode
or cathode heater of the discharge device, d. having means to modify
the temperature of the discharge device, either the temperature
modifying medium being automatically controlled or the discharge
device supply circuit being controlled by the temperature modifying
medium (see section B. on other temperature modifying combinations).
(See Subclass References to the Current Class, below, for a map
of these art areas.)
I. PLURAL LOAD DEVICE SYSTEMS:
Circuits are classified in this class as being plural load device
systems where they have any one or any combination of the following,
and in any circuit relationship, including where one is in a control
circuit of another: a. where the circuit claimed includes two or
more lamps; b. where the circuit claimed includes two or more discharge
devices, at least two being limited in the claims to the gas or
vapor type; c. where the circuit claimed includes at least one lamp
and at least one discharge device limited in the claims to the gas
or vapor type.
J. ART USES AND COMBINATIONS WITH ART DEVICES:
Only to the following limited extent, the lamp and/or discharge
device system claimed is subject to all of the limitations of parts
A through J of this definition. The must be no classification in
any other class on the basis of the art use or combination with
the particular article, device or apparatus claimed. There mere
designation of a lamp by an art name (as an ultraviolet or other
special ray generator) or the mere designation of a discharge device
or one or more of the principal electrodes thereof by an art name
(as a spark plug, igniter, naming a principal electrode as work
to be heated or welded) will not exclude the patent from this class
in the absence of further art limitations. For further details
of the lines with particular arts, see the notes appended to the
main class definition and to the definitions of the subclasses for combinations
with particular articles, devices, or apparatus. See Subclass References
to the Current Class, below.
K. TESTING ELECTRIC LAMPS AND DISCHARGE DEVICES:
Where the system is designed to operate the lamp or discharge
device as a load device and the system includes means to indicate
some condition thereof, the system is classified with the systems
of operation in this class. This Class provides for such operating
systems combined with signal, indicator, or alarm (see Subclass
References to the Current Class, below). Electrical circuits, apparatus,
and methods which are limited in their use to testing the operativeness
or determining the characteristics of electric lamps or electric
discharge devices of any type and which are limited in their use
to the sole purpose of such testing are classified elsewhere, even though
the system includes an electric lamp or discharge device as the
means for indicating the operativeness or characteristics of the
device under test. (See References to Other Classes, below.)
L. OPERATING A LAMP OR A GAS OR VAPOR DISCHARGE DEVICE:
Patents which claim a method of operating a lamp or a gas
or vapor discharge device are classified in this class (315). The
patent is classified in the subclass which provides for the system
which is required to operate the device. For example, a claim which
recites a method of operating a lamp by first passing a current
of one magnitude through the lamp and in then increasing the current flow
through the lamp would be classified in this class as a system having
regulating means in the system (see Subclass References to the Current
Class, below).
FURTHER NOTES:
Lamp And Discharge Device Structure:
Patents claiming an electric lamp or discharge device structure
and means broadly to supply electric energy or potentials thereto
are classified elsewhere as a lamp or discharge device structure.
If the relative magnitude or relationship of the electric energy
or potential is specified in the claims, the patent is classified
as an electrical system and cross-referenced for the lamp or discharge device
structure. Where two or more lamps and/or discharge devices
are structurally combined to form a unitary device (there being
no circuit element in addition to such structure), the structural
combination is classified in the classes noted below even though
the electrodes thereof are interconnected, except in the following
particular instances: the combination of an incandescent filament
lamp and a discharge device structurally combined to form a unitary
structure, the filament connected to form a circuit impedance or
heater for the discharge device load. (For these, see Subclass
References to the Current Class, below.)
For other structures and structural combinations, see References
to Other Classes, below.
Space Discharge Igniters:
This class provides for systems for supplying electric energy
to one or more discharge devices of the "spark plug" or "ignition" type
when the claims are limited to a discharge device. Where the claims
are not so limited, being drawn to an ignition device broadly (not
limited to a discharge device, spark plug, or spark gap), the patent is
placed in the appropriate igniter classification and cross-referenced
to this class. Also ignition systems, even though limited to a
discharge device, when claimed in combination with fuel burning
apparatus, are classified with the type of fuel burning apparatus,
(see also main class definition, section J).
For such ignition device systems and combinations, see References
to Other Classes, below.
Load Devices Other Than or in Addition to Lamps and/or
Discharge Devices:
See section D, above. Where the system claimed includes a
load device other than a lamp and/or discharge device,
even though lamps and/or discharge devices constitute a
part of the system, either as additional load devices or as part
of the system of regulation and/or control of such other
load device, the patent is excluded from this class, and will be
found in the class appropriate to the type of load device or combined
load devices.
Class 315 provides for electrical systems limited to supplying
electric current and/or potential to one or more electronic
tubes of of the gas or vapor type. Many of these systems inherently
convert A.C. to D.C. or D.C. to A.C. Some are inherently oscillation
generators. Where the system is limited by claimed subject matter
to supplying a load circuit, it is excluded from Class 315. Merely
claiming the circuit necessary to connect the anode to the cathode
as a load circuit is not sufficient to exclude the system from Class
315. Claiming a load device, either specifically or broadly in
the output circuit will exclude the system from Class 315. Claiming subject
matter which would not be provided unless the system were to be
used for supplying a load device is sufficient to exclude the system
from Class 315. For example, reciting means in the output circuit
responsive to overload conditions in output circuit to control the system
will exclude the system from Class 315. See References to Other
Classes, below.
SECTION III - SUBCLASS REFERENCES TO THE CURRENT CLASS
for supplying electric current and/or potential to
cathode-ray tubes, and/or cathode-ray tubes combined with
a circuit element which is structurally combined with the cathode-ray
tube so as to form a unitary device.
for subject matter in which cathode-ray tubes are
combined with circuit elements, all of which are structurally combined
therewith to form a unitary device, see main class definition, sections
(A) and (B).
and indented subclasses for electrical circuit elements
(except a mere source of current and/or potential supply,
if claimed) which are not structurally combined with the lamp or
discharge device must be structurally combined with the heating
and/or cooling means.
for subject matter under the class definition, sections
(A) and (B), Structural Combinations With Circuit Elements and Structural
Combinations With Heating And/Or Cooling Means.
and indented subclasses and subclass 49 for the combination
of an incandescent filament lamp and a discharge device structurally
combined to form a unitary structure, the filament connected to
form a circuit impedance or heater for the discharge device load.
for means to modify the temperature of the discharge
device, either the temperature modifying medium being automatically
controlled or the discharge device supply circuit being controlled
by the temperature modifying medium, (see Lines With Other Classes
and Within This Class, section B, above, on other temperature modifying
combinations).
and indented subclasses for systems wherein an impedance
is substituted in the circuit when a lamp or discharge device is
removed therefrom so that the impedance provides a substitute load
on the system.
for operating systems combined with signaling means,
or indicator means, or alarm means operated by some part of the
load device or the electrical circuits therefor to indicate some condition
in the load device or the circuits therefor.
and 129+ provides for supply systems for lamps
and gas or vapor discharge devices which include a signal to indicate
the condition of the load device or the circuit.
a claim which recites a method of operating a lamp
by first passing a current of one magnitude through the lamp and
then increasing the current flow through the lamp would be classified
in this subclass as a system having regulating means in the system.
Gas Separation: Apparatus,
subclasses 80+ for electrostatic precipitators having voltage
supply means or circuitry for applying electrical potential thereto.
Electricity: Circuit Makers and Breakers, appropriate subclasses for electric switches. Some types
of electric switches are closely analogous in structure to some
types of electric space discharge devices. This is especially true with
respect to the type of electric space discharge device where the
electrodes of the discharge device are normally in contact under open
circuit conditions, the electrodes being separated from each other
when the current is applied to the circuit, the space discharge
being established by separating or drawing apart the electrodes.
An electric switch of the thermostatic type where the contacts
of the switch are normally open when no current is applied to the
circuit which includes the switch, the switch including means to
establish an electric space discharge between the contacts, the space
discharge heating the thermostat so that the thermostat moves the
switch contacts into circuit closing position to establish a conductive
path for the current through the contacts and to short-circuit or
extinguish the space discharge, is closely analogous in structure
to space discharge devices of the type which is classified in this
class (315) in
subclasses 56+ as a combined switch and discharge device. The
distinction between electric switches and space discharge devices,
therefore, depends in some cases principally upon the disclosed
purpose of the structure claimed by the patent. Where the space
discharge is only an incident to the separating of the switch contacts
and the purpose of the structure is to open or close a circuit,
the device will be considered an electric switch for the purpose
of classification. Where the purpose of the claimed structure is to
establish an electric space discharge by contacting the electrodes
with each other, the device is considered to be an electric space
discharge device. This class (315) includes, in subclasses 56+,
combined space discharge devices and electric switch structures
where the device claimed includes electrodes other than the switch
electrodes, their supports, or lead-in means for establishing an
electric space discharge. To be classified in Class 315, the device
claimed must include at least one electrode which has no purpose
other than to operate as an electric space discharge electrode. Where
the only discharge electrodes are also switch means, the patent
will be classified in Class 200. For switches which are somewhat analogous
in structure to space discharge devices, see subclass 144, where
the switch is provided with means to separate the switch contacts
from each other to open the circuit, the switch structure including
means to extinguish the space discharge formed when the switch contacts
are opened; subclasses 182+, for mercury and other liquid
contact switches which are closely analogous in structure to mercury vapor
and other liquid electrode lamps and discharge devices.
Chemistry: Electrical and Wave Energy,
subclasses 155+ , 164+, 192.1+, and 298.01+ for methods
for subjecting materials to electric space discharges for performing
chemical changes and analogous purposes. See Class 422, Chemical
Apparatus and Process Disinfecting, Deodorizing, Preserving, or
Sterilizing, subclasses 186+ for apparatus for subjecting
reactants to electromagnetic wave energy (other than visible light)
or corpuscular radiation; e.g. radioactive particles, for initiating
or perfecting a reaction.
Electric Heating,
subclasses 50+ , especially indented subclasses 121.11+ for
systems for supplying electrical energy to arc welding and/or
heating apparatus. Class 315 provides electric systems for supplying
electric current to an electric arc where the arc is specified by
name only as a welding and/or heating arc. The patent
will not be excluded from Class 315 even though one of the electrodes
is named as the material or object broadly defined, such as "the
work to be welded and/or heated". Where the claimed
subject matter is limited to the welding and/or heating
art, such as, for example, by claiming the means for holding, handling,
feeding, and/or moving the work to be welded and/or
heated, the patent is classified in Class 219.
Radiant Energy, is the generic class for electric discharge systems. In
this class,
subclasses 200+ is the generic place for photoelectric device circuits.
Class 315 provides for systems wherein the ultimate load device
in the system is either a lamp or gas or vapor discharge device,
and the system includes means for controlling the operation of the
load device by means of radiant energy. In Class 315, the load device
may be a radiant energy sensitive device; that is a lamp or discharge
device whose operation is altered when subjected to radiant energy,
or the system may include a radiant energy sensitive device such
as a photocell which controls the operation of the load device.
Subclass 251 provides for devices for producing and propagating
a unidirectional stream of neutral molecules or atoms through a vacuum,
usually with thermal velocity. Subclasses 281+ provides
for methods and apparatus for the ionic separation or analysis of
a material utilizing the mass to electric charge ratio of ionic
particles of the material. Subclasses 324+ has methods
and apparatus of irradiating material by corona radiation. Subclasses
432+ is the place for irradiating fluent material which
is contained, supported, or transferred from one place to another.
Subclasses 440.11+ is for a supported object subjected
to charged particles used to inspect the object for a radiant source,
and subclasses 454.11+ in addition to an irradiated object
support, includes a support for a radiation source. Subclasses
458.1+, is the generic place for methods and apparatus
to irradiate fluorescent or phosphorescent devices including self-luminous
articles particularly those used as signalling alignment or indicating
devices. Subclasses 492.1+ is the generic place for the irradiation
of material or objects by wave or particles of energy of the nuclear
or electromagnetic wave type. Where not elsewhere classified, Class
315 includes systems provided with a load device of the con fined
gas or vapor type with means regulating the gas or vapor pressure
in the confined space, or systems having a discharge device load
with means to supply fluent material to the outer electrode discharge
space, or systems having a load device and provided with means to
supply fluent material to the load device to modify the temperature
of the discharge device, only when the disclosed or claimed purpose
of the fluent material supply is to modify the operation of the
discharge device. Where the purpose of the claimed subject matter
is to treat the fluent material either with rays generated by the
discharge, or to subject the material to the influence of the discharge,
the patent is classified in Class 250 or other appropriate class
which provides for the particular art.
Prime-Mover Dynamo Plants,
subclasses 13 , 26, 33, 35, 37, and 41 for such plants having
an internal combustion engine provided with ignition means of the
discharge device type (spark plugs). (Lines With Other Classes
and Within This Class, "Space Discharge Igniters.")
Electrical Transmission or Interconnection Systems,
subclasses 11+ for plural load circuit systems; 43+ for
plural supply circuits or sources, particularly subclasses 48+ and
66+ in which one of the sources of electrical current is a
storage battery (see the class of Electricity: Battery or Capacitor
Charging or Discharging, below, for battery charging and/or
discharging systems); and 154+ for systems for supplying one
or more particular load devices not elsewhere classifiable but particularly
subclass 157 in which the load is a lamp or discharge device. (Lines
With Other Classes and Within This Class, "Load Devices
Other Than or in Addition to Lamps, and/or Discharge Devices.")
Electric Lamp and Discharge Devices, appropriate subclasses for the structure of electric lamps
and discharge devices, per se. See
subclasses 1+ for a plurality of discharge devices (including
discharge device lamps) or a discharge device and an incandescent
lamp which are structurally combined to form a unitary device.
(Lines With Other Classes and Within This Class, "Lamp
and Discharge Device Structure.")
Electric Lamp and Discharge Devices: Consumable
Electrodes,
subclass 7 provides for systems for supplying such type discharge device
and another type discharge device or lamp. (Lines With Other Classes
and Within This Class, "Load Devices Other Than or in Addition
to Lamps, and/or Discharge Devices.")
Electric Lamp and Discharge Devices: Consumable
Electrodes, appropriate subclasses for electric lamps and discharge
devices of the consumable electrode type, and such devices in combination
with the electric system for supplying current or potential to the
device.
Electric Lamp and Discharge Devices: Consumable
Electrodes, which class takes such structures, even though combined
with lamp and/or discharge devices of other types. (Lines With
Other Classes and Within This Class, "Lamp and Discharge
Device Structure.")
Electricity: Battery or Capacitor Charging or Discharging, appropriate subclass for a battery or capacitor
charging or discharging system. (Lines With Other Classes and Within
This Class, "Load Devices Other Than or in Addition to
Lamps, and/or Discharge Devices.")
Electricity: Power Supply or Regulation Systems,
subclasses 227 and 291 and the subclasses specified in the notes
to the definitions of those subclasses for systems for controlling the
magnitude of the current and/or voltage in a single circuit
having a discharge device as the control means. The discharge device
may be either a vacuum tube or a gas or vapor tube. The systems
in Class 323 include more than the mere circuit for supplying electric
current or potential to the discharge device for merely causing
a discharge to take place within the tube or for regulating the
discharge within the tube. Many of the systems in Class 323 are closely
analogous to the systems in this class. See Lines With Other Classes
and Within This Class, in the class definition of Class 323 for the
line between this class (315) and Class 323. (Lines With Other
Classes and Within This Class, "Load Devices Other Than
or in Addition to Lamps, and/or Discharge Devices.")
Electricity: Measuring and Testing,
subclasses 403+ for electrical circuits, apparatus, and methods
which are limited in their use to testing the operativeness or determining
the characteristics of electric lamps or electric discharge devices
of any type and which are limited in their use to the sole purpose
of such testing. (See Lines With Other Classes and Within This
Class, "Testing Electric Lamps and Discharge Devices," above.)
Amplifiers, appropriate subclasses for amplifier systems including
gas tubes, cathode-ray tubes, traveling wave tubes, magnetrons,
etc., which are of the type of tubes in circuits classified in this
class.
Oscillators, is the generic class for electrical oscillators.
Many systems using electric lamps of the gaseous or vapor discharge
type inherently generate oscillations during operation. Class 315,
therefore, provides for all systems for merely supplying electric
current or potential to gaseous or vapor discharge devices whether
the system is claimed as an oscillation generator or merely as a
lamp circuit provided that the system is not limited by claimed
subject matter to use as an oscillation generator, such as, for
example, means to transfer the oscillating electric energy to another
circuit or means to use the oscillating energy.
Electricity: Electrothermally or Thermally Actuated
Switches, appropriate subclasses for thermal switches which
are combined with space discharge devices.
Communications: Electrical, appropriate subclasses for electric signals and
signaling systems wherein an electric lamp is used as the signal
means, and for miscellaneous signaling systems which include discharge
devices as a part thereof. Merely defining the lamp as a signal
will not exclude the patent from Class 315, even though the circuit
of the amp is controlled in accordance with the operated or nonoperated condition
of some device. Class 315 provides for supply systems for lamps
and gas or vapor discharge devices which include a signal to indicate
the condition of the load device or the circuit (see Subclass References
to the Current Class, above).
Computer Graphics Processing and Selective Visual
Display Systems, appropriate subclasses for selective control of
data presentation on a display device, especially subclasses 74.1-75.2
for display elements arranged in matrix having cathodoluminescent
type.
Electricity: Electrical Systems and Devices,
subclasses 247+ for the detonation of an explosive charge. (Lines
With Other Classes and Within This Class, "Space Discharge
Igniters.")
Illumination, generic class for illuminating devices provided
with means to modify and/or distribute the illumination,
and/or with protective means, such as casings, globes,
or guards, and for the supports and holders for lamps (other than
mere sockets) and such electric lamp illuminating devices when claimed
in combination with the source of supply for the lamp.
Electric Power Conversion Systems, appropriate subclasses for various conversion systems including
electronic tubes and their control. The systems of Class 363 are
closely analogous to the systems of this class (315). In many cases,
the distinction between a Class 363 system and a Class 315 system
will be significant claiming of a load circuit or load device.
Many of the systems of Class 315 will inherently operate as a current
convertor because of the basic property of many electronic tubes
to conduct current in one direction only. In such cases, the inclusion
of the load circuit or load device may be determinative as to whether
the system as claimed relates to a conversion system. The following
subclasses of Class 363 are of particular interest. See
subclasses 50+ for protective systems for electronic tube current convertors;
subclasses 74+ for current conversion systems with automatic
voltage and/or current magnitude control which may include electronic
tube control; subclasses 83, 94, and 99 for current conversion systems
with electronic tube line circuit control means; subclasses 111+ for
electronic tube current conversion systems; subclass 151 for electronic tube
phase conversion systems; subclasses 166+ for electronic
tube frequency conversion systems. For the line between this class
(315) and Class 363, see Lines With Other Classes and Within This
Class in the class definition of Class 363.
Electric Power Conversion Systems,
subclasses 74+ for rectifying and derectifying systems with automatic
voltage and/or current magnitude control wherein the control
means may be an electronic tube having a discharge control means.
Many of the systems in Class 363 are closely analogous to the systems
in this class (315). See Lines With Other Classes and Within This
Class in the class definition of Class 363 for the line between
this class (315) and Class 363. (Lines With Other Classes and Within
This Class, "Load Devices Other Than or in Addition to
Lamps, and/or Discharge Devices.")
Industrial Electric Heating Furnaces,
subclasses 60+ for electric arc furnaces. Class 315 provides
for systems for supplying electric current to arc furnaces provided
that the arc furnace is included by name only. Where the claims
include significant furnaces structure, or are otherwise limited
to the furnaces art, the patent is classified in Class 373.
X-Ray or Gamma Ray Systems or Devices, appropriate subclasses, particularly
subclasses 91+ for circuits for energizing or controlling X-ray
tubes. (Lines With Other Classes and Within This Class, "Load
Devices Other Than or in Addition to Lamps, and/or Discharge Devices.")
Chemical Apparatus and Process Disinfecting, Deodorizing,
Preserving, or Sterilizing,
subclasses 22+ for processes of disinfecting, deodorizing, preserving,
or sterilizing using an electric space charge device.
Combustion,
subclasses 264+ for a spark electrode in front of or adjacent the
fuel discharge of a burner. (Lines With Other Classes and Within
This Class, "Space Discharge Igniters.")
Electrical Computers: Arithmetic Processing and
Calculating,
subclass 540 for the use of a CRT in digital arithmetical operations,
and subclass 849 for the use of CRT in function generation.
SECTION V - GLOSSARY
AUXILIARY DISCHARGE ELECTRODE
An electrode which is connected in the circuit so that
the discharge is initiated between it and one of the principal electrodes,
the auxiliary discharge conditioning the discharge space between
the principal electrodes so that a discharge between the principal
electrodes can be established.
DISCHARGE CONTROL DEVICE
Any means associated with the discharge device (for example
only, an electromagnet, a control grid or an auxiliary discharge
electrode) intended to be used to control or influence the discharge
between the principal electrodes of the discharge device.
DISCHARGE CONTROL ELECTRODE
Any electrode which is designed to influence or control the
discharge between the principal electrodes. It may be a control
grid or an auxiliary discharge electrode. It may depend for its
effect on either its electro-static effect or on the current flow
thereto.
ELECTRIC SPACE DISCHARGE DEVICES
The shorter expression "DISCHARGE DEVICES" is used
in these definitions, are defined for the purpose of classification
in this class as including any device which is intended to have
an electrical current flow between two spaced electrodes, at least
part of the path followed by the discharge being constituted by
a gas, vapor, or vacuum.
GAS OR VAPOR DISCHARGE DEVICE
Any type of electric space discharge which, as claimed, depends
upon ionization of a gas or vapor for its operation. Discharge devices

a confined (enclosed) atmosphere are included in this definition.
HIGH-VACUUM TUBE
A vacuum tube evacuated to such a degree that its electrical
characteristics are essentially unaffected by gaseous ionization.
LAMPS
Are defined for the purpose of classification in this
class as including a device designed for converting electrical energy
into ray energy, regardless of whether the ray energy is within
the visible or invisible part of the spectrum, but excluding (1)
generators of X-rays, and (2) generators designed primarily to generate
infrared rays. Lamps may be in the form of electric space discharge devices,
for which see the next paragraph.
LOAD DEVICE
The device to which the system supplies electrical energy
and which, as claimed, constitutes the final or ultimate device
for utilizing the electrical energy of the system.
PRINCIPAL ELECTRODES
The "two spaced electrodes" referred
to in the definition of electric space discharge devices, between
which the discharge current is primarily intended to flow.
This subclass is indented under the class definition. Subject matter for supplying electric current and/or
potential to cathode-ray tubes, and/or cathode-ray tubes
combined with a circuit element which is structurally combined with the
cathode-ray tube so as to form a unitary device.
(1)
Note. Cathode-ray tubes are defined for the purpose of classification
in this subclass as an electric space discharge device which is
provided with means to form the electric space discharge into a restricted
beam or ray, usually pencil like.
(2)
Note. Where a system includes the cathode-ray tube system
as a part thereof, the patent is excluded and will be found with the
particular art which provides for the complete system.
(3)
Note. These subclasses do not include systems which are limited
by claimed subject matter to using the cathode-ray tube for controlling
the current and/or potential supplied to a load device
other than a cathode-ray tube, for which see the class appropriate
to the load device. Where the output circuit claimed includes more
circuit elements than is necessary for the mere current and/or potential
supply for the cathode-ray tube, the system is considered to be
limited to use for supplying and/or controlling the current
and/or potential to load device and, therefore, excluded
from these subclasses.
(4)
Note. Systems which include a cathode-ray tube
having either a discharge intensity modulating means or a discharge focusing
means and discharge deflecting means are excluded from these subclasses
where the claims include significant features of the circuits for supplying
the controlling currents and/or potentials to the modulating
means or focusing means and the deflecting means from the controlling
source. For example, a system which includes means for separating
the video or image and synchronizing signals from each other and applying
them to the cathode-ray tube is classified with the art to which
the system relates; i.e., television if the purpose of the system
is to reproduce an optical image.
Included in these subclasses are systems which recite broadly
means for applying current and/or potential to the intensity control
means or the focusing means and to the deflecting electrodes as
well as patents which claim systems for controlling the discharge
intensity or the focusing solely in dependence upon conditions in
the cathode-ray tube current or potential supply system, such as, for
example, applying a control potential to the intensity control means
or focusing means in dependence upon the rate of ray deflection
or in dependence upon the direction of ray deflection (blackout circuits).
(5)
Note. Merely claiming either the source of signal potential
for controlling the discharge intensity control means, the focusing
means, or the discharge deflecting means will not exclude the patent from
these subclasses as long as the source of signal potential is claimed broadly
so that it could be any source of potential. Where the system claimed includes
a source of signal potentials and means to separate the potentials
and to apply one to the vertical sweep means, and the other to the
horizontal sweep means, the patent is not excluded from these subclasses
as long as the source of signal potential is claimed broadly and
is no more than a source of periodic potentials. Where such synchronizing
circuit for the ray deflecting means is claimed in addition to significant
features of the ray modulating circuit, the patent is excluded.
(6)
Note. Merely claiming the source of signals to control the
start of the ray deflecting circuit as a synchronizing potential will
not exclude the patent from these subclasses as long as the source
of ray deflecting control potential is claimed broadly and is only
the control potential for the ray deflecting means.
(7)
Note. These subclasses do not include the combination of
a cathode-ray tube and mechanical or optical devices, such as lenses,
mirrors, et cetera, which are used with the cathode-ray tube even
if the system of supply for the cathode-ray tube is claimed. Merely
using a voltage to deflect a cathode-ray beam so as to form a scale
upon the screen of the cathode-ray tube will not exclude the patent from
Class 315.
Radiant Energy,
subclasses 281+ for methods and apparatus for the ionic separation
or analysis of materials utilizing the mass to electric charge ratio of
ionic particles of the material.
Electric Lamp and Discharge Devices,
subclass 2.1 for the structural combination of a cathode-ray tube
combined with an electric space discharge device or an electric
lamp so as to form a unitary device, and subclasses 364+ for
cathode-ray tube structures.
Electricity: Measuring and Testing,
subclass 88 for devices for indicating the phase relations
of electric quantities, which devices comprise cathode-ray tubes,
and subclass 121 for cathode-ray galvanometers. Where the system
claimed includes means for applying a current or potential under examination,
or an unknown current or voltage, to the cathode-ray tube, the system
is not excluded from Class 315 unless some means is claimed to enable
the desired information to be derived other than merely observing the
trace of the ray on an uncharted luminous screen, or unless the
cathode-ray tube is claimed in combination with significant features
of the circuit to be investigated. Merely naming the circuit to
be investigated as a source of pulsating or alternating current
will not be sufficient to exclude the patent from Class 315.
Recorders, appropriate subclass for cathode-ray devices in
combination with photographic recording means. Class 346 provides
for such combinations where the system for operating the cathode-ray
tube is claimed when the system is of general application and not
otherwise classified.
Facsimile and Static Presentation Processing,
subclasses 409 through 424for synchronizing in facsimile systems which include
a cathode-ray tube. See Notes (4), (5), and (6) above for the line
between Class 358, subclasses 409-424 and these subclasses (1.1-1.18).
Television Signal Processing for Dynamic Recording
or Reproducing,
subclass 130 for cathode-ray tubes in combination with optical
means, such as lenses, mirrors, etc., used for television recording.
This subclass is indented under subclass 1. Subject matter in which cathode-ray tubes are combined with
circuit elements, all of which are structurally combined therewith
to form a unitary device, see main class definition, sections (A)
and (B).
(1)
Note. The circuit element may be mounted within or on the
base or envelope of the cathode-ray tube.
(2)
Note. These subclasses include the combination of a cathode-ray
tube load device and a circuit element where the tube and the circuit
element are formed of separable parts, but are provided with means
for fastening or assembling the parts together to form a unitary
device.
(3)
Note. Examples of devices considered to be circuit elements
are electric switches, resistances, capacities, inductors, transmission
lines of the distributed parameter type (e.g., coaxial lines), waveguides,
antennas, transformers, structures formed so as to act as if possessed
of distributed inductance and capacitance (e.g., resonators) and
any other circuit element.
(4)
Note. The circuit combined with the cathode-ray tube need
not be a circuit element to be used in the circuit of the cathode-ray
tube load device, but may be provided with separate terminals so
as to be usable in any desired relation.
(5)
Note. This and the indented subclasses include cathode-ray
tubes wherein the electrodes and/or the electrode leads
are formed so as to function as inductances. This and the indented
subclasses do not include cathode-ray tubes wherein the electrodes
are formed of resistive material and no other circuit element is
combined with the cathode-ray tube.
(6)
Note. Patents claiming a cathode-ray tube in combination
with a separable socket receptacle or connector for the cathode-ray
tube, the socket receptacles or connector including a circuit element, are
not classified in these subclasses, but will be found either in
subclass 1 or in the other subclasses under subclass 1.
and indented subclasses for other types of electric
discharge devices and for electric lamps combined with circuit elements,
all of which are structurally combined to form a unitary device.
Electric Lamp and Discharge Devices,
subclasses 365+ provides for cathode- ray tubes which have a photosensitive
electrode. Included in these subclasses in Class 313 are cathode-ray
tubes where the photosensitive electrode is not in physical contact
with a conductive supporting base or where the conductive supporting
base is of high resistance material. No effort has been made to
separate the cathode-ray tubes with photosensitive electrodes such
as mosaic electrodes from each other on the basis of whether or
not the electrode has a capacitor effect, a resistance effect, or is
conductively connected to its lead-in conductor. All such cathode-ray tube
structure has been placed in subclasses 365+ of Class 313.
This subclass is indented under subclass 3. Subject matter in which a transmission line or device arranged
to propagate a traveling electromagnetic wave is constructed and
arranged to have a wave component the velocity of which is reduced
in comparison to the wave velocity in free space; and in conjunction
therewith are means for generating an electron beam whose path is
in such proximity to the path of said traveling wave component as
to permit an exchange of energy between such beam and the traveling
wave propagated along the transmission path.
(1)
Note. Transmission line or device is defined to include any
device which is used to guide or constrain electrical wave energy
and to convey the energy from one place to another. Included are conductors
and waveguides.
(2)
Note. The transmission device may be constructed as a spiral
or helix so that the wave has an axial velocity component along
the helix which is lower than the free space velocity of the wave,
or the transmission device may be loaded as by inductive members
to reduce the velocity of the traveling wave.
for other cathode-ray tubes which have structurally
combined therewith an inductive or distributed parameter-type inductive
structure (e.g., waveguide, coaxial cable, or parallel wire transmission
line). See subclasses 5+ for traveling wave-type cathode-ray
tubes having a hollow transmission line (e.g., waveguide) for a
traveling wave, and having an electron beam means which is transverse
to the transmission line so that energy may be exchanged between the
beam and the traveling wave.
for other traveling wave-type electronic tubes having
a velocity reducing-type transmission line but which do not have
the space discharge path focussed or otherwise shaped into a beam.
Amplifiers,
subclass 43 for amplifier systems having traveling wave tubes. See
Lines With Other Classes and Within This Class and References to Other
Classes in the Class Definition of Class 330.
Wave Transmission Lines and Networks,
subclass 22 for transmission lines of the distributed parameter
type (e.g., waveguides, long lines) having dissipating terminations,
subclasses 138+ for delay networks, subclasses 32+ for
impedance matching networks for transmission lines, subclass 81
for transmission lines of the long line with an attenuator means,
and attenuators especially designed for use over a frequency band
or for use in transmission lines of the distributed parameter type,
and subclasses 236+ for the structure of transmission lines of
the distributed parameter type.
This subclass is indented under subclass 3.5. Subject matter which is provided with a plurality of transmission
lines or devices, or which has the transmission line or device constructed so
as to have a section which has different characteristics from another
section.
(1)
Note. For example, the device may have a plurality of beams
and a plurality of transmission lines, or a single beam with a plurality
of transmission lines arranged parallel to each other or in series
relation along the path of the beam, or may have the transmission
line arranged to have different retarding times along its length or
have portions provided with coatings or other means to provide different
attenuation at different portions of the line.
(2)
Note. This subclass does not include subject matter under
subclass 3.5 where the transmission line or device is only provided
with impedance matching means designed to facilitate the coupling of
the transmission line or device to an input or output coupling means
(even though such impedance matching means involves differences
in structure in the transmission line or device such as changing
the spacing of the turns of a spiral transmission line). Such subject matter
is classified in subclass 3.5 in the absence of other structure,
causing classification in this subclass.
5.27, 5.28, and 5.39+, for traveling wave
tubes having a plurality of hollow transmission lines (e.g., waveguides),
at least one line being designed to propagate a traveling wave,
and having means producing an electron beam transverse to the transmission
lines so that energy may be exchanged between the beam and the energy
in the transmission lines.
Wave Transmission Lines and Networks,
subclass 22 for transmission lines of the distributed parameter
type having dissipating terminators, subclass 81 for transmission
lines and devices with an attenuator means and attenuators especially
designed for use with transmission lines and devices of the distributed
parameter type, and subclasses 236+ for the structure of
transmission lines and devices of the distributed parameter type.
This subclass is indented under subclass 3. Subject matter wherein the circuit element structurally
combined with the cathode-ray tube is an inductor or a structure
formed so as to act as if it possessed inductance with or without
capacitance.
(1)
Note. The inductive circuit structure may be a waveguide,
a coaxial line, a hollow resonator, or a parallel wire transmission
line or any other structure having or acting as if it had inductance or
inductance and capacitance.
for other discharge devices which have structurally
combined therewith a waveguide, coaxial cable, or other transmission
line having distributed inductance and capacitance.
for magnetrons which have an electrode with a portion
formed to provide both distributed inductance and capacitance and
a magnetic means for influencing the space discharge.
and the subclasses specified in the notes to the
definition of that subclass, for other discharge devices which are structurally
combined with an inductive impedance.
Wave Transmission Lines and Networks,
subclasses 219+ for electric resonators of the distributed parameter
type, per se, and subclasses 236+ for other transmission
line structure having distributed inductance and capacitance such
as waveguides, coaxial cables, etc.
This subclass is indented under subclass 4. Subject matter wherein the inductor or inductive and capacitive
device constitutes a substantially closed hollow conductive structure having,
or acting as if it had distributed inductance and/or capacitance,
the ray traversing at least part of the hollow space, and usually
passing through the conductive structure by openings provided in
the conductive structure.
(1)
Note. The conductive structure may be a waveguide, cavity
resonator, or coaxial line. An electromagnetic field usually exits
in the hollow space, energy being transferred between the ray and
the field. A parallel wire Lecher-type line with the ray passing
between the wires is not, in itself, a hollow distributed parameter device
for classification here, but rather is classified in subclass 4
above. However, where the Lecher line has added portions to provide
a hollow space or includes holes in its wires for passage of the
ray, classification is in these subclasses (5+).
(2)
Note. For classification here the ray may originate within
the device and either pass beyond or terminate within the device;
or the ray may originate beyond the device and either pass through
or terminate within the device. Where the ray merely passes across
an opening in the hollow distributed parameter device without entry,
classification is in subclass 4 above, even though a coupling exists
between the ray and the electromagnetic field within the device.
for other electric discharge devices having an inductive
impedance which is structurally combined with the discharge device
connected between two of the electrodes of the discharge device.
Amplifiers,
subclasses 45+ for amplifiers having an electron beam tube coupled
to cavity resonator, including those of types classified in this
and indented subclasses.
Oscillators,
subclasses 81+ for electrical oscillators using a beam tube wherein
the beam of charged particles passes through or into a hollow distributed
parameter device, particularly indented subclass 83 wherein the beam
passes through plural cavities. See also the reference to Class
331 under "SEARCH CLASS" in the class definition.

another ray which passes through or in the same device.
This subclass is indented under subclass 5. Subject matter including a magnetron, the hollow device
through which the ray passes constituting the resonator of the magnetron.
(1)
Note. The subject matter of this subclass usually is a magnetron
having an additional cathode projecting a ray through the magnetron
resonator for tuning purposes.
for distributed parameter resonator type magnetrons,
and especially subclass 39.57 for such magnetrons with variable
tuning by electron emission in or adjacent the resonator space,
no means being included to form the emission into a restricted beam
or ray.
This subclass is indented under subclass 5. Subject matter wherein each of a plurality of distinct rays
pass through or in a single hollow device.
(1)
Note. A plurality of rays exit as when projected from separate
or distinguishable cathodes. When a single cathode projects a ray
which is broken into a plurality of pencil rays as by an apertured mask
or other dividing structure, these pencil rays are not considered
plural for purposes of classification in this subclass. When two
distinct cathodes produce each a ray which merges over at least
a part of the ray path, classification is not barred from this subclass.
See especially indented subclass 5.15. A mere plurality of structures
each having a hollow distributed parameter device with a ray passing
therethrough is not classified here, but elsewhere under subclass
5.
for a hollow distributed parameter device with a
ray passing through or in, and a second ray also passing through
or in and produced by the first ray through secondary emission.
for a hollow distributed parameter device, where
the ray, after passing through or in, returns to the hollow device,
and especially indented subclass 5.23 where the device is thermally
tuned as by a cathode-ray.
This subclass is indented under subclass 5.14. Subject matter wherein the plurality of rays are projected
along the same path, at least during passage in or through the hollow
device.
(1)
Note. Mere intersection in the hollow device of two rays
projected in different directions is not sufficient for classification
here, but rather in subclass 5.14 above.
This subclass is indented under subclass 5.14. Subject matter together with an additional hollow distributed
parameter device, the plurality of rays passing through or in the
additional device.
This subclass is indented under subclass 5.16. Subject matter wherein one of the rays is projected in a
reverse direction from the other ray or rays through the respective
hollow devices, to constitute a feedback coupling from the output
to the input device.
This subclass is indented under subclass 5. Subject matter wherein substantially all of the ray passes
from the interior of the hollow device and beyond the exterior of
the device, and then returns to the interior of the device.
(1)
Note. The ray may return to the hollow device by the same
path as it leaves the device as a result of reflection, or the ray may
follow a curved path as a result of deflection, or the ray may follow
a straight path, the device being formed to intercept the ray after
the ray passes out of the device.
(2)
Note. For classification in this and the indented subclasses,
it is necessary that the ray return to the interior of the device.
When the ray merely returns to engage the exterior of the device,
classification is in subclasses 5.24+ or 5.33.
This subclass is indented under subclass 5.18. Subject matter wherein the ray in returning to the hollow
device retraces the path followed in leaving the device, and/or
wherein the ray reenters the hollow device through the same aperture
as it left the device.
This subclass is indented under subclass 5.19. Subject matter wherein the hollow device is resonant at
a particular frequency, together with structure for changing or
permitting change in the resonant frequency.
(1)
Note. Reflex klystrons whose frequency is controlled by variation
of the repeller voltage are not classified here, but in subclass
5.19, if otherwise within the scope of subclass 5.19.
This subclass is indented under subclass 5.21. Subject matter, wherein the hollow device has a flexible
wall to adjust the shape or a dimension of the device, usually for
varying the width of the gap in the device across which the cathode-ray
travels.
for plural hollow distributed parameter devices
having a ray passing through or in, at least one of the devices
having a flexible wall for tuning purposes.
This subclass is indented under subclass 5.22. Subject matter including structure which is connected to
or part of the flexible wall for moving this wall in response to
a temperature change induced in the structure, or for compensating
for movement of this wall due to temperature effects.
This subclass is indented under subclass 5. Subject matter wherein structure is provided for changing
the path of substantially the entire ray from a first direction
to a second direction.
(1)
Note. Only patents are classified here the entire cross section
of whose ray is deflected from a first to a second direction. Focusing,
concentrating, dispersing, and velocity sorting the ray are classified
elsewhere. See for example subclasses 5.34+ and 5.38.
(2)
Note. The deflection may be greater than 90° and
may even be 180° to constitute a complete reflection of
the ray. However, see subclasses 5.18+ for subject matter
under subclass 5 where the ray is reflected or deflected to return
to the device.
(3)
Note. The deflected ray may also be rotated, as for example,
in a conical path.
for a hollow distributed parameter device wherein
the ray after passing through or in is deflected or reflected to
return to the device. See also (2) Note above.
Oscillators,
subclass 80 for electric wave generating systems utilizing
a charged particle or electron beam tube with beam sweeping or deflecting means.
This subclass is indented under subclass 5.24. Subject matter wherein the hollow device is provided with
an opening in its wall, the ray sweeping between the opening and
the wall to be alternately passed and blocked.
This subclass is indented under subclass 5.26. Subject matter including a plurality of hollow distributed
parameter devices through or in which a single ray passes, at least
one of the hollow devices deflecting the ray.
(1)
Note. The hollow devices may be arranged to successively
deflect the ray passing through or in or one device may be arranged
to deflect the ray while the other device collects the deflected
ray.
This subclass is indented under subclass 5.24. Subject matter, including a plurality of hollow distributed
parameter devices having a single ray passing through or in.
This subclass is indented under subclass 5. Subject matter wherein the ray has a cross sectional dimension
which is significantly related to and an appreciable part of the
wavelength of signal energy in the cathode-ray tube, and/or wherein
the ray has a significant shape; the dimension and/or shape
usually persisting over the entire path of the ray, and at least
during passage through the device.
(1)
Note. The patents in this main subclass (5.29) usually have
a flat weblike ray.
(2)
Note. The particular shape and/or dimension is usually
produced by a cathode of particular shape and/or dimension;
e.g. elongated, annular, or cylindrical cathode.
(3)
Note. Subject matter including grids of distributed parameter
devices which have openings peculiarly adapted to pass rays of a
particular transverse shape or dimension are classified in this
subclass, the ray or the means producing the ray being recited in
the claim.
for a hollow distributed parameter device with a
ray passing through or in, wherein the deflection of the ray provides
a ray path having a particular shape or dimension, such as a particular
bent or spiral ray.
for a distributed parameter device with a ray passing
through or in, wherein the grids have a particular shape or dimension
not related to the transverse shape or dimension of the ray. See
(2) Note above.
This subclass is indented under subclass 5.29. Subject matter, wherein the ray is formed as a hollow tube
with the cathode at one end, which ray may be circular or rectangular

of the disk or coaxial with the center of the disk.
This subclass is indented under subclass 5. Subject matter wherein the hollow device also constitutes
a ray anode or cathode, or wherein the ray anode or cathode is an
integral part of the hollow device, or wherein the ray anode or cathode
is mounted in a wall of the hollow device and has an appreciable
portion within the interior space of the hollow device.
(1)
Note. Where the ray anode or cathode is integral with the
hollow device, but entirely external to the hollow space and separated
from the hollow space by a grid, classification is not in this subclass, but
in subclasses 5.37 or 5.38 below.
This subclass is indented under subclass 5. Subject matter wherein the cathode-ray tube is provided
with means for focusing and/or concentrating the cathode-ray.
(1)
Note. Concentrating or focusing the cathode-ray is used in
this definition to mean either to reduce the cross section area
of the cathode-ray across its width or to bring the ray to a focus;
that is, the ray is either converged toward a point, or is diverged
as if it had originated at a point.
for a hollow distributed parameter device wherein
the entire cross section of the ray passing through or in is substantially
uniformly deflected in one direction.
This subclass is indented under subclass 5.34. Subject matter, wherein the focusing or concentrating means
provides a magnetic field in a direction to focus or concentrate
the ray.

Note. This focusing means may be a permanent magnet, or a
conducting coil or loop with or without a magnetic core or yoke.
This subclass is indented under subclass 5. Subject matter wherein the hollow device and its electrodes
are readily separable.
(1)
Note. The patents classified here usually disclose disc electrodes
projecting through the envelope of a tube, and a cavity resonator
or waveguide having its opposite walls secured to the respective electrodes,
as by screw or spring clamping.
This subclass is indented under subclass 5. Subject matter wherein the hollow device is provided with
a grid and significant ray reacting details of this grid are claimed.
(1)
Note. The grids of this subclass are only those which are
associated with the device at its gap, and through which the ray
passes. Accelerating or focusing grids disposed along the ray path
but not an intimate part of the hollow device, are not within the
scope of this subclass. Subclasses 5.34+ and 5.41, respectively, provide
for ray focusing and concentrating and ray accelerating between
hollow devices generally within the scope of subclass 5.
(2)
Note. A hollow device provided with a mere plurality of grids
is not considered to be a significant grid detail for classification
here. A particular relationship between the plurality of grids
must be claimed or significant details must be claimed for classification
in this subclass.
for a hollow distributed parameter device with a
ray of a particular transverse shape or electrical dimension passing
through or in, the grids of the device having openings shaped to pass
a ray of such shape or dimension.
This subclass is indented under subclass 5. Subject matter including an anode or collector, significant
details of the anode or collector being claimed.
(1)
Note. The anode or collector as here used is the electrode
which the ray strikes after passing into or through the last hollow
device, and where the particles forming the ray are removed.
This subclass is indented under subclass 5. Subject matter including a plurality of hollow distributed
parameter devices with the ray passing through or in at least two
of the devices.
(1)
Note. For classification here the ray must pass through or
in at least two of the devices. A system of two devices with the
ray passing through or in only one device, the other device being merely
coupled to the ray as by being connected to the cathode and control grid,
without the ray passing through or in the other device is not classified
here, but elsewhere under subclasses 5+.
for one or more hollow distributed parameter devices
with a plurality of rays passing through or in and especially indented
subclasses 47+ for a plurality of such devices.
Oscillators,
subclasses 6+ and 83 for electric wave generating systems utilizing
a charged particle or electron beam tube wherein the beam passes through
plural hollow resonators (e.g., Klystron).
This subclass is indented under subclass 5.39. Subject matter including structure for increasing or decreasing
the velocity of the ray particles uniformly over the cross-section
area of the ray during their passage between the hollow devices.
for hollow plural distributed parameter devices
with structure for focusing or concentrating the ray between the devices,
which may involve accelerating or decelerating the beam differently
over its cross section.
for plural hollow distributed parameter devices
wherein the devices are excited from a common source for accelerating
the ray during passage across the gaps of the respective devices.
This subclass is indented under subclass 5.39. Subject matter wherein the interiors of the hollow devices
are excited directly from a common source, the phase of the energy
as applied to the interiors of the respective devices being such
as to accelerate the ray during passage across the gaps of the respective
devices, whereby the ray is progressively accelerated during passage
through the devices.
This subclass is indented under subclass 5.39. Subject matter wherein an electrical connection exists between
the interiors of the hollow devices to transmit electrical energy
between the devices, but in a direction opposite to that which the
ray transmits.
(1)
Note. The feedback connection may be either regenerative,
degenerative, or sufficient to produce oscillations. If the feedback
connection is a ray, in addition to the ray normally passing through
the devices, classification is in subclass 5.17 above.
(2)
Note. If the claims recite even broadly a load or output
fed by the cathode-ray tube circuit herein classified, the load
or output being disclosed as external to the envelope of the cathode-ray
tube, classification is in Class 327, Miscellaneous Active Electrical
Nonlinear Devices, Circuits, and Systems, appropriate subclasses,
or in Class 331, Oscillators, appropriate subclasses, depending whether
the energy fed back is insufficient or sufficient respectively to
sustain oscillation. However, a coupling probe or loop to abstract
energy from the output device is not sufficient to preclude classification
here (5.44), even though designated as an output or load.
for devices with a feedback connection therebetween,
the connection being by a ray in addition to the ray normally passing
through the devices. See also (1) Note above.
This subclass is indented under subclass 5.44. Subject matter including three or more hollow distributed
parameter devices through which the ray passes with an electrical
connection between at least two of the devices.

resonant frequency may be adjusted, and which are adpated for passage
of a cathode-ray through or in.
Tuners, appropriate subclasses for tuned networks for use
in wave energy apparatus and comprising inductance and capacitance
elements in circuit arrangement and in which structure is provided
for adjusting one or both of these elements for changing the mean
resonant frequency of the circuit.
This subclass is indented under subclass 5.46. Subject matter wherein at least two of the hollow resonant
devices include frequency changing structure and wherein the frequency changing
structures of the respective devices are linked together; e.g.,
mechanically or electrically, so that the resonance frequencies
of the respective devices are changed simultaneously.
(1)
Note. Two such devices whose tuning is independently adjustable
but which may each be adjusted together to change the resonant frequencies
as by manual manipulation are not classified in this subclass.
For classification here, there must be a positive linkage between
the devices to produce simultaneous frequencies change, although
independent frequency change may also be present in addition.
This subclass is indented under subclass 5.46. Subject matter wherein at least one of the hollow devices
has, for tuning purposes, a flexible wall to adjust the shape of
a dimension of the device, usually for varying the width of the
gap in the device across which the cathode-ray travels.
for a plurality of hollow distributed parameter
devices having flexible walls, which are linked together for simultaneous

the claimed system. Where the claimed system is classified in this
class, the patent is classified in this or the indented subclasses, and

is supplied with current from another source of supply of a diverse
type.
(1)
Note. Distinction should be made between subject matter claiming
energizing or bias potentials which may turn on a display either
entirely or in a nonimage mode, classifiable here, and subject matter
claiming selective energizing, pulsing or other input responsive
signaling which results in a display producing a light image or
message which subject matter is classifiable in Class 345.
(2)
Note. The type of current (energizing or bias) supplies which

of subclass 160. Other examples of diverse current sources may be lines
carrying different "phases" of a clock pulse source,
or lines carrying different time based pulses.

current being connected to the principal cathode and the principal electrode
and one of the principal electrodes.
for systems wherein the load device is a plural

This subclass is indented under subclass 169.1. Subject matter in which the effect of the energizing currents
is to make the discharge path in the discharge device move from

of pulse input into a register, and added count in a counter, or
the input of display array control signals into a gas panel display.
Caveat: Where "writing", "erasing",
data responsive, or other selective structure or function is recited,
such a claim to the combination of display panel and selective control
is classified in Class 345.

in the circuit so as to control and/or modify the current
and/or potential supplied to such single ultimate load
device, the patent is classified as a plural load device system, if
(a) the controlling and/or modifying device is a lamp,
or (b) the controlling and/or modifying device is limited
in the claims to being a gas or vapor discharge device. Conversely,
such a system is not classified as a plural load device system where
the controlling and/or modifying device is claimed broadly
as a discharge device even though it is disclosed as a gas or vapor
discharge device.

REGULATION OF THE CONTROL CURRENT AND/OR POTENTIAL APPLIED TO DISCHARGE CONTROL DISCHARGE DEVICE LOADS BY PHASE SHIFTING MEANS
This subclass is indented under the class definition. Systems having a load device which is a discharge device
provided with a discharge control means, such as a grid electrode,
an electromagnet for influencing the space discharge, or an auxiliary
starting electrode, the discharge device being either (1) supplied
with a pulsating and/or alternating current and/or
(2) the cathode-anode circuit of the discharge device being so connected
in the system that a pulsating and/or alternating current
flows therein; the system including means to apply current and/or
potential to the control means, the circuit controlling the application
of the control potential including phase shifting means, so that
the control current and/or potential may be applied to
the control means in time phase relation to the pulsating and/or
alternating current in the supply circuit and/or in the cathode-anode
of the load device.
(1)
Note. Neither the current and/or potential applied
to the discharge device nor the control means need be a pulsating and/or
alternating current and/or potential. For example, the
load device may be supplied with discharge current from a source
of unidirectional current with the system so arranged that a circuit
connecting the cathode-anode of the discharge device has a pulsating
current flowing therein, the control means being supplied with unidirectional
current, the system being provided with circuit elements including
phase shifting means responsive to the pulsating current in the cathode-anode
circuit to control the time of application of the unidirectional
current and or potential to the control means.
(2)
Note. When the current supply for the discharge device is
an alternating or pulsating current, and the discharge device is
provided with an auxiliary starting electrode which is supplied
with pulsating or alternating current which is out of phase with
the alternating current in the discharge supply circuit, the patent
is classified as a polyphase supply system in subclass 137 and indented
subclasses, note especially subclasses 145 and 147. Where the system
includes means to supply the auxiliary starting electrode with pulsating
current from the supply circuit, and the auxiliary electrode circuit includes
phase shifting means to shift the phase of the alternating current
in the auxiliary electrode circuit with respect to the current in
the supply circuit, the patent is classified in subclass 140 as
a phase multiplying system. Where the claims only recite a control
device for the discharge device, even though an auxiliary starting
electrode is disclosed, the patent is classified in this subclass (194)
or the indented subclasses.
(3)
Note. Where the discharge device is supplied with discharge
current from a source of pulsating and/or alternating current
and the control means is supplied with a pulsating and/or
alternating current and/or potential, the current and/or potential
in the control circuit need not have its phase shifted with respect
to the supply current, but the phase shifting means may only determine
the time of application of the control current and/or potential
to the control means with respect to the current wave of the supply current.
(4)
Note. Systems wherein the current and/or potential
supplied to the control means is merely varied in magnitude, the magnitude
of the control current and/or potential with respect to
the supply current for the load device determining the time at which
the control means becomes effective to alter the operation of the
discharge device are not included. For such systems, see the subclasses under "SEARCH
THIS CLASS, SUBCLASS" below.

Note. Where a single lamp or a single discharge device is
the ultimate load device, and the system includes an additional
lamp and/or discharge device in the circuit which is connected
in the circuit so as to control and/or modify the current
and/or potential supplied to such single ultimate load
device, the patent is classified as a plural load device system, if
(a) the controlling and/or modifying device is a lamp,
or (b) the controlling and/or modifying device is limited
in the claims to being a gas or vapor discharge device. Conversely,
such a system is not classified as a plural load device system where
the controlling and/or modifying device is claimed broadly
as a discharge device even though it is disclosed as a gas or vapor
discharge device.
The controlling and/or modifying device may be connected
in the control circuit of the discharge device where the ultimate
load device is a discharge control discharge device, and the same
basis of classification is used as is set forth above.

limited in the claims to the gas or vapor type which are included as
load devices in this class are not classified in this subclass or
the indented subclasses, even though one of the devices is disclosed

device. Such patents are classified in the other appropriate subclasses
in this class as a plural load device system. This subclass and the

wherein the system includes a rectifier and or a discharge device
of the type which is not included as a load device in this class.
