Abstract
Abstract A self-retaining adsorbent container including a cylindrical cup-shaped casing of porous material, adsorbent in the casing, a porous end wall secured to the edge of the cup-shaped casing at its open end by a rim which is more rigid than the material of the cup-shaped casing, and diametrically spaced concave indentations in the casing and the cover for receiving spaced pipes in a refrigerant receiver.

Claim 6
Dependent Claim
100 words
In a vessel having spaced pipe portions therein, an adsorbent container comprising a porous casing having a porous outer wall and an end wall, adsorbent in said porous casing, concave indentation means in said porous outer wall for receiving said spaced pipe portions to mount said adsorbent container within said vessel, another pipe portion in said vessel, an open end on said another pipe portion, and a conduit secured to said end wall and including a portion located outside of said casing for mounting on said open end to thereby conduct fluid into said casing from said another pipe portion.
Claim 7
Dependent Claim
42 words
In a vessel as set forth in claim 3 wherein said porous outer wall is part of a cup-shaped member having a second open end, and wherein said end wall is secured to said cup-shaped member to close said second open end.
Claim 8
Dependent Claim
30 words
In a vessel as set forth in claim 4 wherein said cup-shaped member includes an edge at said open end, and wherein said end wall is secured to said edge.
Claim 9
Dependent Claim
45 words
In a vessel as set forth in claim 5 wherein said end wall includes an outer edge, and wherein said outer edge is secured to said edge of said cup-shaped member by fusion to produce a relatively stiff peripheral rim portion for rigidizing said casing.
Claim 10
Dependent Claim
31 words
In a vessel as set forth in claim 6 wherein said relatively stiff peripheral rim portion includes second concave indentation means in alignment with said concave indentations in said outer wall.
Claim 11
Dependent Claim
22 words
In a vessel as set forth in claim 7 wherein said concave indentation means comprise two indentations located in diametrically opposed relationship.
Claim 12
Dependent Claim
