520,526. Vapour engines power plant. TAILLEFERRE, H. July 5, 1938, No. 19854. [Class 122 (iii)] A power plant for submarines, torpedoes &c. is operated by liquefied or solidified gas raised in temperature by exothermic reactions involving the medium in which the apparatus moves the exhaust being soluble in said medium, thereby not revealing its presence. As shown in Fig. 1, a reservoir A contains liquefied ammonia and a heating-coil B. An engine M is supplied from the dome F. The engine exhaust passes from a pipe R into an absorber-heater O. The liquid in which the vessel moves, e.g. sea water is introduced into the tank O by a floatcontrolled valve. The hot solution of ammonia is driven by the pump V through the coil B which exhausts to the sea. In the construction shown in Fig. 2, the reservoir has two heating- coils B, C. A tube D surrounds the end of a pipe E. A reservoir of sulphuric anhydride G with an air chamber H at the top is arranged as shown. An engine I actuates pumps J1-J3. A mixer K and a superheater L are shown between pumps J J2. The pump J1 draws sulphuric anhydride from the tank G and passes it into the mixer K where it unites with water from the reservoir O supplied by pump J2. The generated heat superheats the ammonia driven through the boiler L by the pump J3. The ammonia passing to the engine M entrains in an injector P the exhaust of the engine I thereby reducing its back pressure. Liquid is introduced into the base of the reservoir A in equal volume to that removed to maintain the balance of the machine. The excess water in the reservoir O and the hot solution of ammonium sulphate from the superheater L are used in the coils B, C.
