368,710. Refrigerating; refrigerators. ALLYNE, E. E., 13301, Shaker Boulevard, Cleveland, Ohio, U.S.A. Dec. 3, 1930, No. 36504. [Class 29.] Absorption machines.-The generator-absorber vessel 11 of a reversing system fitted beneath the cooling compartment 2 of a domestic cabinet is provided with depending tubes 27, 28 from which extend a gilled loop 29 located in a flue 14 at the back of the cabinet, the loop being cooled during the absorption phase by air passing up the flue. A damper 41 in the flue is adjusted under the influence of a thermostatic element 46a in the cooling compartment. The flue is divided by a vertical partition 12, and a water tank 47 for the condenser coil 38 is located at one side of the bottom of the flue. During the generating phase evolved refrigerant passes through an air-cooled loop 15, a trap 17, a gilled rectifier pipe 20, and an air-cooled loop 35 serving as a preliminary condenser and then passes by a pipe 37 to the condenser. Liquefied refrigerant rises through a pipe 39 to a receiver 51, which communicates with a header 53 of closed-ended evaporator tubes 54. An ice-making pan 60 supported from the header 53 is adapted to receive condensation moisture from a tray 65 below the evaporator tubes. The evaporated refrigerant returns by the same path to the trap 17 and is there diverted by a pipe 32 to the tube 27 of the generator-absorber. The end of the tube 32 is enlarged and sealed, as shown in Fig. 3, and the refrigerant passes noiselessly into the liquor through small openings 34.
