Abstract: 579,125. Generating combustion products under pressure. WATSON, F. (Aktiebolaget Milo). Oct. 31, 1939, No. 29088. [Class 51 (i)] [Also in Group XXVI] A power plant for vehicles, vessels such as submarines and torpedoes comprises a combustion chamber for producing motive fluid supplied with fuel, air and a liquid oxygen carrier such as hydrogen peroxide, manual or automatic means being provided to vary the proportion between the air and liquid oxygen carrier and acting so as to increase the liquid oxygen carrier supply after starting the plant while reducing the air supply or for increasing simultaneously the supply of fuel and liquid oxygen carrier after initial operation and for ensuring that the air supply is automatically reduced. In the plant shown in Fig. 1, which is suitable for a submarine, air, fuel and liquid oxygen carrier are supplied from vessels 15, 19 and 40 respectively to the combustion chamber 13 from which gases pass through a pipe 14 to a turbine 10 which drives through reduction gearing 12 the propeller shaft 11. When starting up the plant, the valve 17 is opened and air passes through a constant pressure valve 18 to the combustion chamber 13 and to the turbine which is thereby rotated. Eccentrics 28, 45 on the shaft 11 actuate pumps 22, 43 to effect the supply of fuel and liquid oxygen carrier to the combustion chamber through pipes 21, 42. The fuel is ignited by the device 66 and the gases produced. pass to the turbine. Upon the pressure reaching a predetermined pressure the back pressure in the air supply pipe 16 causes the valve'18 togradually close. A hand lever 35 regulates through a system of levers the stroke of the pump plungers 23, 44 and the supply of fuel and liquid oxygen carrier. The ratio between the supplies of fuel and liquid oxygen carrier is varied by a turnbuckle 37 in the lever system.. The exhaust from the turbine 10 passes to a condenser 51, the condensate being collected in a container 52 and the gaseous combustion products being led to atmosphere or stored in a vessel 61 by pumps 55, 62 driven from the shaft 11. Fig. 2 shows a plant for driving torpedoes. Upon launching the torpedo a rod 70 is actuated to open the valve 17 to admit air from the chamber 15 to the combustion chamber 13. Valves 72, 77, 82, 85 are also actuated to supply liquid oxygen carrier and fuel to the combustion chambers through pipes 42, 21 from the vessels 40, 19 and admit pressure air from the pipe 16 to the vessels 40, 19 through pipes 81, 83.

Abstract: 845,108. Starting prime movers; self-contained supply systems. SIEMENS SCHUCKERTWERKE A.G. Sept. 24, 1956 [Sept. 23, 1955], No. 29203/56. Addition to 840,928. Class 38(4). A self-contained A.C. supply system having a star-connected generator G permanently connected to the load lines R, Y, B is arranged to start and stop automatically in response to the opening and closing of the load switches V1-V4. Before operation of the plant, a supervisory relay UR is connected in series with the generator star point, the load, and an auxiliary source B. Closure of a load switch energizes winding I of relay UR, operating relay ER and winding I of relay AN. Contact an1 operates the starter motor, er3 the choke (where applicable), zr1 the ignition coil (or fuel release for diesel engines), and UR is held over contact er1. Voltage measuring relay GR operates at about 70-80% of the generator rated voltage, and disconnects relay ER and winding I of UR. Winding II is, however, energized from current transformers W through rectifiers GL2, GL3 and voltage limiter GL1. Disconnection of the load releases UR and energizes relay AB thus breaking the ignition circuit over ab1. On voltage relay contact gr2 disconnecting thermal switch T3, contact t3 de-energizes relay RR and hence AB and BR. If the engine fails to start, a thermal switch contact t1 counter-energizes winding I of relay AN and resets the circuit to its initial condition. After several successive starts another thermal switch T2 operates a locking relay SR preventing further operations and illuminating a warning lamp ML. The control equipment may be mounted separately from the generator set and auxiliary source and connected by means of a two-part coupling VS, AK.
