Figure 1:
A drawing is captioned “Condensation Trap.”  An upright hollow
cylinder with a gas inlet pipe on the left and a gas outlet pipe
on the right is depicted (This is labeled as Warm Creep Surface).
A smaller cylinder labeled “Cryogen Container” (also identified as
Cold Trapping Surface) is suspended inside the first cylinder.
Gas entering the first cylinder flows around the inner cylinder
and exits through the outlet pipe.

Figure 2:
A drawing is captioned “Figure 2. Absorbent Trap.”  An upright
hollow cylinder with a gas inlet pipe on the left and a gas outlet
pipe on the right is depicted (This is labeled as Warm Creep Surface).
A smaller cylinder labeled “Absorbent Container” (also identified
as Trapping Media) is suspended inside the first cylinder.  Gas
entering the first cylinder flows around the inner cylinder and
exits through the outlet pipe.

Figure 3:
A drawing captioned “Figure 3. Absorbent Trap.”  An upright hollow
cylinder with a gas inlet pipe on the left and a gas outlet pipe on
the right is depicted (This is also labeled as Warm Creep Surface).
A smaller cylinder labeled “Absorbent Container” (also identified as
Trapping Media) occupies the entire interior of the first cylinder.
Gas entering the first cylinder flows through the inner cylinder and
exits through the outlet pipe. Figure 3 differs from Figure 2 in that
the absorbent container appears to fill the entire trap, whereas in
Figure 2 it only fills about three-quarters of the trap.
