Title: Improvements in gas turbine and jet propulsion power plants
IPC: F02C3/00
Filed: 1949-07-01
Abstract: 699,854. Gas turbine or jet propulsion plant; motor power plant. ETESSAM, A. H. Aug. 14, 1950 [July 1, 1949], No. 17492/49. Class 110(iii) [Also in Groups XXVII and XXVIII] A gas turbine or jet propulsion power plant comprises a centrifugal or axial flow compressor which delivers low pressure air to a reciprocating engine, the engine having a high pressure valve arranged to open and close on the compression stroke and permit expulsion of some of the air from the engine cylinder at a high pressure, a high pressure turbine, the high pressure air being expanded in this turbine, the engine being arranged to have sufficient fuel burnt in the air remaining in the cylinder after the high pressure valve has closed to drive the engine, a low pressure turbine, the exhaust from the engine being heated and expanded in the low pressure turbine, at least one of turbines driving the compressor and at least one of the turbines or its exhaust being arranged to produce useful power. In Fig. 1 a two-stroke or four-stroke compression ignition engine 5 is supplied with air under pressure by means of a centrifugal or axial flow compressor 1 driven by a high pressure turbine 18 and a low pressure turbine 20. The high pressure turbine receives heated high pressure air from a heater 15 which in turn receives compressed air from the cylinder of the engine through a valve 8 which is opened during the compression stroke. The exhaust from the turbine is supplied to a combustion chamber 12 in which fuel is burnt by means of a burner 13 the products together with the exhaust gases from the engine passing to the low pressure turbine 20. The engine may or may not supply external power from its crank shaft. In a modification the turbine 18 instead of receiving heated air is supplied by combustion products from a combustion chamber in which fuel is burnt in the high pressure air from the engine. The exhaust from the turbine 18 passes to the combustion chamber of the turbine 20 which is also supplied with the exhaust of the engine and air from the compressor 1 which is heated by the exhaust of the turbine 20. The exhaust of the turbine 20 heats this air in a heat exchanger which latter if desired may be built around the cylinder of the engine so that heat lost from the cylinder walls in addition to heat from the exhaust of the turbine 20 is absorbed by the air. Fig. 3 shows a two stroke engine having combustion chambers 32, 33 on opposite sides of a piston 30. High pressure valves 38, 39 respectively supply compressed air during the respective compression strokes. The engine drives a drum 45 which operates inlet valves 36, 37, fuel injectors 34, 35, and the valves 38, 39. The drum surrounds the shaft 46 of the turbines 18, 20 and compressor 1 but rotates independently thereof. The engine may have several cylinders each piston driving the drum by a pin engaging a single slot of the drum..

Title: Improvements in or relating to the stabilisation of ships
IPC: G05D1/08
Filed: 1930-06-14
Abstract: 357,138. Stabilizing ships. GES FR ELEKTRISCHE APPARATE, Marienfelde, Berlin. June 14, 1930, No. 18263. Convention date, July 4, 1929. [Class 113 (i).] In arrangements for damping rolling or pitching by means of carriages of large mass which are reciprocated athwart or fore and aft ship, in opposition to the respective motions, the motor 1 driving the carriage is operated from a main switch 33 which is displaced by a rolling-angle indicator 5 through the auxiliary motor 4 and the bevel gearing shown to contact successively with the contacts 30, 32 which with the resistances 29, 31, as well as the field circuit 26. lie in the current circuit 27, 28. With the ship on an even keel, this voltage control suffices to minimize the rolling motion. Should the vessel have a list, the motion of the carriages becomes unbalanced and this is corrected by passing the movements of the carriage through the synchronous motor 9, as well as those of the rolling-angle motor to a screw 1 on which a nut 12 works. Supported from the nut by springs 13, 14, a damping cylinder 15 carries an arm 20 with a brush 21 which works across an auxiliary switch 3 also in the main current circuit. If owing to the unilateral movements of the carriage, the movements of the nut are persistently greater in one direction than the other, the cylinder is displaced against the action of the springs and the brush 21 of the voltage distributer 3 moves away from its central position and the unbalanced movement of the carriage is corrected. The adjustment of the brush can also be effected by the hand controls 24, 22, and the carriages can also be subjected to the control 7 which is influenced by the velocity of the angle of roll.
