Abstract: An absorption refrigeration system having a generator that includes a first, or primary, heat exchanger operatively connected to a low temperature energy source and that includes a second, or auxiliary, heat exchanger operatively connected to a high temperature energy source. Control means are provided so that energy is supplied to the generator from the high temperature energy source only after energy is extracted from the low temperature energy source and additional energy is required by the system. Various embodiments are disclosed showing different ways of positioning and operating the primary and auxiliary heat exchangers. Another embodiment illustrates a condenser system that efficiently operates to condense refrigerant vapor regardless of the distribution of the energy contribution between the high and low energy sources.

Abstract: An alcohol reclaiming apparatus for use in an absorption refrigeration system having a separator operatively connected to the system condenser for removing alcohol from liquid refrigerant prior to passing the refrigerant from the condenser section to the evaporator section of the system. The separated alcohol is delivered directly into the system absorber, thereby bypassing the evaporator, to promote continuous circulation of alcohol through the system whereby the performance of the system is maintained at a relatively high level.

Abstract: An alcohol circuit for use in an absorption refrigeration system for circulating alcohol through the system along an independent path of travel which prevents the alcohol from stagnating within the evaporator section of the system. Further means are provided to precondition the alcohol prior to its introduction into the absorber section to enhance the effective use of this additive within this section.

Abstract: Apparatus for electrolyzing a liquid having an electrolytically regeneratable ionic oxidizing agent, the apparatus including an anode having a tubular portion and a cathode having a cylindrical portion inside the tubular portion of the anode. The opposing surfaces of the tubular anode portion and the cylindrical cathode portion are substantially uniform and concentric about a common axis. In one embodiment, the anode and cathode are each made of a plurality of portions, with means for electrically connecting anode-cathode pairs of said portions in series.
