Abstract
Abstract Continuously operating adsorption refrigeration plant, comprising a gas-tight housing having at least one expeller chamber and at least one adsorption chamber disposed therein sequentially following each other in a close loop, sealing gates disposed between the chambers for preventing an uninhibited exchange of gaseous coolant between the chambers, an endless structure disposed in the housing including carriers for solid adsorbent of a coolant and connection members spacing the carriers apart from each other, the carriers being movable one after the other through the chambers of the housing.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
87 words
Continuously operating adsorption refrigeration plant, comprising a gas-tight housing having at least one expeller chamber and at least one adsorption chamber disposed therein sequentially following each other in a closed loop, sealing gates disposed between said chambers for preventing an uninhibited exchange of gaseous coolant between said chambers, an endless structure disposed in said housing including carries for solid adsorbent of a coolant and connection members spacing said carriers apart from each other, said carriers being movable one after the other through said chambers of said housing.
Claim 2
Dependent Claim
87 words
Continuously operating adsorption refrigeration plant, comprising a gas-tight housing having at least one expeller chamber and at least one adsorption chamber disposed therein sequentially following each other in a closed loop, sealing gates disposed between said chambers for preventing an uninhibited exchange of gaseous coolant between said chambers, an endless structure disposed in said housing including carries for solid adsorbent of a coolant and connection members spacing said carriers apart from each other, said carriers being movable one after the other through said chambers of said housing.
Claim 3
Dependent Claim
41 words
Adsorption refrigeration plant according to claim 1, wherein said endless structure is in the form of a relatively thin annular disc, said carriers are segments of said disc and said connection members are sections of said disc disposed between said carriers.
Claim 4
Dependent Claim
47 words
Adsorption refrigeration plant according to claim 1, wherein said connection members are in the form of an annular ring with a relatively small cross section and said carriers are in the form of segments of an annular disc spaced apart from each other on said annular ring.
Claim 5
Dependent Claim
19 words
Adsorption refrigeration plant according to claim 1, wherein said connection members are formed of a poor heat conducting material.
Claim 6
Dependent Claim
36 words
Adsorption refrigeration plant according to claim 2, wherein said housing is an annular chamber having the shape of a flattened torus and having a cross section corresponding to the dimensions of said carrier and connection members.
Claim 7
Dependent Claim
36 words
Adsorption refrigeration plant according to claim 3, wherein said housing is an annular chamber having the shape of a flattened torus and having a cross section corresponding to the dimensions of said carriers and connection members.
Claim 8
Dependent Claim
43 words
Adsorption refrigeration plant according to claim 5, wherein said carriers have mutually opposite edges, and said annular chamber of said housing has a wall with an interior surface, and including guides disposed on said interior surface for said opposite edges of said carriers.
Claim 9
Dependent Claim
56 words
Adsorption refrigeration plant according to claim 2, wherein said sealing gates are in the form of diametrically opposite flexible intermediate members having dimensions corresponding to the dimensions of said carriers and having interior surfaces, and including sealing sliders disposed on said interior surfaces, said sealing sliders being movable in opposite directions for varying the distance therebetween.
Claim 10
Dependent Claim
25 words

Adsorption refrigeration plant according to claim 3, wherein said sealing gates are in the form of sealing sliders being movable in opposite directions and being supported in recesses formed in said housing at locations corresponding to the dimensions of said carriers.
Claim 12
Dependent Claim
29 words
Adsorption refrigeration plant according to claim 10, including compression springs biasing said sealing sliders, and cams disposed on said connection members for controlling the movement of said sealing sliders.
Claim 13
Dependent Claim
34 words
Adsorption refrigeration plant according to claim 1, including at last one other housing in vicinity of and coaxial to said first-mentioned housing being combined with said first-mentioned housing to form a battery of housings.
Claim 14
Dependent Claim
22 words
Adsorption refrigeration plant according to claim 1, including heat exchanging ribs protruding outwardly from said housing in vicinity of said expeller chamber.
