Abstract
Abstract A disposable cartridge having chamber means to be filled with selected fluid-treating material and fluid flow conduit means to direct a fluid stream through the fluid-treating material for removal of impurities or undesirable substances carried by the fluid. The cartridge includes a frame member adapted to receive perforate plate members in spaced relation to form alternate fluid flow chambers and chambers to hold the selected fluidtreating material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
207 words
A fluid-treating cartridge comprising a generally U-shaped member having an open end; at least two first perforate plate means to be received by such frame member and retained in mutually spaced relation within said frame member to form a gas flow chamber therebetween, which chamber communicates with said open end of said frame member; at least one spacer bar extending between said two first perforate plate means through said chamber to support said two first perforate plate means at points intermediate said frame member; at least two second perforate plate means to be received by said frame member and disposed in spaced relation from said first two perforate plate means sandwiched therebetween to define adsorbent receiving chambers between said first perforate plate means and said second perforate plate means; spacer means to connect said first plate means to said second plate means to retain selected spacing between said first and second plate means, cover plate means to be fixed adjacent the open end of said frame member, said cover plate means having aperture means communicating with said gas flow chamber defined by said frame member and said first perforate plate means; and, adsorbent material contained in said chambers defined between said first and second perforate plate means.
Claim 2
Dependent Claim
207 words
A fluid-treating cartridge comprising a generally U-shaped member having an open end; at least two first perforate plate means to be received by such frame member and retained in mutually spaced relation within said frame member to form a gas flow chamber therebetween, which chamber communicates with said open end of said frame member; at least one spacer bar extending between said two first perforate plate means through said chamber to support said two first perforate plate means at points intermediate said frame member; at least two second perforate plate means to be received by said frame member and disposed in spaced relation from said first two perforate plate means sandwiched therebetween to define adsorbent receiving chambers between said first perforate plate means and said second perforate plate means; spacer means to connect said first plate means to said second plate means to retain selected spacing between said first and second plate means, cover plate means to be fixed adjacent the open end of said frame member, said cover plate means having aperture means communicating with said gas flow chamber defined by said frame member and said first perforate plate means; and, adsorbent material contained in said chambers defined between said first and second perforate plate means.
Claim 3
Dependent Claim
48 words
The fluid treating cartridge of claim 1 wherein said spacer bars extend through said first and second perforate plates means and through said gas flow chamber wherein ring means are selectively disposed on said spacer bar means to provide support for said first and second perforate plate means.
Claim 4
Dependent Claim
45 words
The fluid treating cartridge of claim 1 wherein said frame member includes inset surfaces extending around said frame member inset from the edges of said frame member wherein said first plate means are received by said inseT surfaces and are fastened to said inset surfaces.
Claim 5
Dependent Claim
42 words
The apparatus of claim 1 wherein said adsorbent receiving chamber is defined by said frame member and said first and second perforate plate means are filled with adsorbent and said second perforate plate means is received by the surface of said adsorbent.
Claim 6
Dependent Claim
37 words
The apparatus of claim 3 wherein said first perforate plate means includes peripheral upstanding flange means directed toward said second perforate plate means and said second perforate plate means are received by the upstanding peripheral flange means.
