Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
179 words
In an absorption refrigerator having a nonelectric boiler heating system, a box having a coolable interior and a side at which refrigerating equipment is mounted, said refrigerating equipment including a boiler and a heating burner located below said boiler for heating the same, electrically energizable blower means carried by said box, at least one centrally apertured ceramic disc formed with radial bores and disposed above said heating burner and substantially concentrically to said heating burner and said boiler so that heat originating in said burner is concentrated in the central aperture of said ceramic disc, and thermocouple means comprising a multiplicity of serially-connected thermocouple elements having respective hot junctions located within the central aperture of said ceramic disc, respective cold junctions located radially beyond the periphery of said ceramic disc and respective means extending through said radial bores for mutually connecting the respective hot and cold junctions to one another, said thermocouple means being electrically connected to said blower means for energizing the latter with electricity generated in said thermocouple means by the heat originating in said heating burner.
Claim 2
Dependent Claim
179 words
In an absorption refrigerator having a nonelectric boiler heating system, a box having a coolable interior and a side at which refrigerating equipment is mounted, said refrigerating equipment including a boiler and a heating burner located below said boiler for heating the same, electrically energizable blower means carried by said box, at least one centrally apertured ceramic disc formed with radial bores and disposed above said heating burner and substantially concentrically to said heating burner and said boiler so that heat originating in said burner is concentrated in the central aperture of said ceramic disc, and thermocouple means comprising a multiplicity of serially-connected thermocouple elements having respective hot junctions located within the central aperture of said ceramic disc, respective cold junctions located radially beyond the periphery of said ceramic disc and respective means extending through said radial bores for mutually connecting the respective hot and cold junctions to one another, said thermocouple means being electrically connected to said blower means for energizing the latter with electricity generated in said thermocouple means by the heat originating in said heating burner.
