IPC: F02C7/32
Filed: 1972-01-18
Abstract: 1349421 Gas turbine plant - fuel supply system SUNDSTRAND CORP 18 Jan 1972 [3 March 1971] 2442/72 Heading F1G The invention relates to a drive system comprising a turbine driven by hot gases from a decomposition chamber, fuel being supplied from a tank to the decomposition chamber by means of a pump, there being means for pressurising the fuel tank so as to force fuel to the pump, also means for purging the fuel system upon pump shut-down. The system comprises a fuel tank 25 connected by line 37 to the inlet of pump 35, the pump discharging through line 39 and a flow control system, through line 41 to the decomposition chamber 20. Gases discharge from the chamber 20 through line 18 and nozzle 15 to drive the turbine 12, the gases finally discharging through line 17 to atmosphere. The turbine shaft 13 is connected to drive the fuel pump 35 and also through reduction gearing 11, a hydraulic pump 10. The pump 10 may be for emergency hydraulic supply on an aircraft. A tapping is taken from the turbine inlet nozzle 15 through line 33 to the fuel tank whereby the fuel in the tank is pressurized and caused to flow through line 37 to the inlet of fuel pump 35. The fuel tank contains an inner flexible lining 26 on which the pressurizing gas acts. Two solid fuel starting chambers 22 are associated with the decomposition chamber 20 and at starting, pressure gas from one of the start chambers passes to the decomposition chamber and thence to the turbine which drives the fuel pump 35 and hydraulic pump 10; a portion of pressure gas also passes through line 33 to pressurize the fuel tank whereby fuel passes through line 37 to the inlet of pump 35. Fuel then passes through lines 39, 41 to the decomposition chamber whereby decomposition of the fuel is initiated. The flow control valves are normally open as shown so that fuel enters port'46 of valve 45 and discharges through port 48 through line 41 to the decomposition chamber. In the event of fuel pressure increasing above a predetermined value the valve member 68 of control valve 60 is forced downwardly so communicating passages 62, 63 whereby fuel under pressure passes through line 57 causing the valve member 50 to move downwardly so closing off port 48 and communicating ports 46, 75 whereby fuel is returned through line 54 to pump inlet. Means are provided for purging the pump discharge line 39 after shut-down, pressurizing gas in line 33 passing through valve 84 and line 82 to the discharge line 39 and causing any remaining fuel to pass to the decomposition chamber; the valve 88 in the discharge line would close during purging. Means are provided for testing the apparatus by utilizing gas such as nitrogen under pressure. A nozzle 90 is provided whereby such gas may be directed on to the turbine. A line 96 is provided whereby such gas may be directed into the pump discharge line 39 for testing operation of the flow control valves; a connection 98 to atmosphere is opened during such testing.

Abstract: 362,219. Electrolysis. MENTZEL, A., 2, Nordsternstrasse, Sch÷neberg, Berlin. Jan. 27, 1931, No. 2667. [Class 41.] In apparatus for the electrolytic decomposition of liquids under pressure of the kind in which there is separate circulation of the anolyte and catholyte, heating and cooling devices are applied to the circulating systems and adjusted to maintain the circulations in balanced relation so as to avoid pressure disturbances which might lead to mixing of the generated gases. In the apparatus shown, the catholyte and hydrogen pass from the cell Z by a pipe i to a separator A whence the catholyte returns to the cell by a pipe a provided with a cooling device K and a heating device L in its rising part. The gas passes through a washer W, a pressure-equalizing vessel D containing mercury, a chamber R for catalytic removal of oxygen and pressure equalizers B and C. Similar devices are provided on the anolyte side. Feed water from a vessel N is supplied to the catholyte side only. Throttle valve E, El are provided in the catholyte and anolyte circuit and connection between the two circuits is regulated by a valve x. The purifier R is provided with a preheater V heated by the exhaust from the purifier. The vessel B is connected by a V-tube with a chamber G containing a gas normally maintained at constant pressure. The chamber C contains a diaphragm the space above which is in communication with the chamber G and actuates a valve to permit release of gas to the collecting pipe only when a predetermined pressure is attained. If a given maximum pressure in the system is exceeded by choking of the outlet valve or otherwise, gas passes over from the vessel B into the chamber G so as to equalize the pressure on both sides of the diaphragm and thereby to prevent damage. The pressure meter P consists of a pivoted tube containing mercury which is displaced by the fluctuations of pressure. This device may be modified to act as an automatic control.
