Self-retaining adsorbent bag unit

In a refrigerant receiver having a bottom wall and a side wall and having a U-shaped portion of pipe extending axially of said receiver with a portion of said U-shaped portion of pipe in contiguous relationship to said bottom wall of said receiver, the improvement comprising an adsorbent unit including first and second porous fabric container members having first and second porous fabric walls, respectively, first and second container edge portions on said first and second container members, respectively, first and second central container portions on said first and second container members, respectively, adsorbent in said container members, and yoke means for securing said first and second container members to each other, said yoke means being positioned between said bottom wall of said receiver and said U-shaped portion of said pipe in contiguous relationship to said bottom wall of the receiver to thereby hold said adsorbent unit in position within said container with said container members lying between opposite sides of said U-shaped portion of said pipe and said side wall of said receiver, said yoke means having a central yoke portion and first and second spaced yoke portions on opposite sides of said central yoke portion, first and second opposite yoke edge portions on said yoke means, third and fourth opposite yoke edge portions on said yoke means, said central yoke portion and said first and second spaced yoke portions lying between said first and second opposite yoke edge portions of said yoke means and between said third and fourth opposite edge portions of said yoke means, said first, second, third and fourth opposite yoke edge portions defining the length and width dimensions of said yoke means, said first and second opposite yoke edge portions being connected to said first and second container members, respectively, with said defined yoke length and yoke width dimensions of said yoke means defining a connecting portion of said yoke means which extends between said first and second container members to couple portions of said first and second container edge portions proximate said yoke means in spaced relationship, said yoke means extending between said container members with said first and second spaced yoke portions extending in a direction away from said first and second yoke edge portions, respectively, and extending in a direction away from said first and second central container portions, respectively.

An adsorbent unit comprising first and second porous fabric container members having first and second porous fabric walls, respectively, first and second container edge portions on said first and second container members, respectively, adsorbent in said container members, and elongated planar sheet-like yoke means for coupling said first and second container members relative to each other in spaced relationship for mounting said adsorbent unit relative to an external structural member, said elongated planar sheet-like yoke means having a central yoke portion and first and second spaced yoke portions on opposite sides of said central yoke portion, first and second opposite yoke edge portions on said yoke means, third and fourth opposite yoke edge portions on said yoke means, said central yoke portion and said first and second spaced yoke portions lying between said first and second opposite yoke edge portions of said yoke means and between said third and fourth opposite yoke edge portions of said yoke means, said first, second, third and fourth opposite yoke edge portions defining the yoke length and the yoke width dimensions of said yoke means, said first and second opposite yoke edge portions being connected to said first and second container members, respectively, with said defined yoke length and yoke width dimensions of said yoke means defining a connecting portion of said yoke means which extends between said first and second container members to couple portions of said first and second container edge portions proximate said yoke means in spaced relationship, said elongated planar sheet-like yoke means extending between said container members with said first and second spaced yoke portions extending in a direction away from said first and second yoke edge portions, respectively, and extending in a direction away from said first and second central container portions. respectively, said yoke means also including a yoke thickness dimension, and said container members including container length, container width and container thickness dimensions, and said yoke means being fabricated from flexible material which permits said container members and said yoke means to be oriented with their respective thickness dimensions extending in substantially the same directions when said container members are oriented in end-to-end relationship with their length dimensions extending in substantially the same direction and their width dimensions extending substantially parallel to each other, and which permits said yoke thickness dimension and said container thickness dimensions to have portions extending substantially perpendicularly to each other when said container members are oriented with their length dimensions extending substantially parallel to each other and said container width dimensions extending substantially parallel to each other.
