Patent GB-787997-A (GB)
Title: Improvements in or relating to fuel supply systems for internal combustion engines
IPC: F02K1/16
Filed: 1954-11-08
Abstract: 787,997. Gas turbine jet propulsion plant; centrifugal and axial flow pumps. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Nov. 8. 1954 [Nov. 10. 1953]. No. 32241/54. Classes 110 (1) and 110 (3). A gas turbine engine fuel supply system comprises a fuel pump driven by the engine, a valve in the connection between the inlet of the pump and the fuel storage means and a second valve connected to a conduit between the pump discharge and the engine, the arrangement being such that when the first valve is closed, the second valve is operated to release fuel trapped in the pump. Fuel is supplied to the reheat burners 20 of a gas turbine jet propulsion engine by a pump 33 constantly driven by gearing 30, 31 from the front end of the compressor. A bleed valve 40 is provided in the pump discharge conduit 36 between the pump discharge 35 and a non-return valve 38 which is biased to the closed position. The valve 40 shown comprises a valve member 44 loaded to the open position by a spring 45 but it may be servo operated and controlled by movement of the throttle lever 26. A fuel source (not shown) is connected to the pump inlet 35 by a conduit 46 containing a gate valve 47. The valve 47 is operated by an electric motor 48 so that when the throttle lever 26 is moved into the afterburning range 52 the valve is opened; and when moved into the normal operating range 26a the valve is closed when it is desired to augment the thrust of the engine, the lever 26 is moved into the range 52. This allows fuel to flow to the pump 33 and the resulting pressure in the conduit 36 closes the bleed valve 40 and opens the non-return valve 38. When it is desired to cut off the afterburner, the lever 26 is moved into the range 26a. The valve 47 is then closed and the pressure in the conduit 46 falls. As a result valve 38 closes and valve 40 opens, to allow the fuel trapped in the conduit 36 between the pump 33 and valve 38 to be scavenged to atmosphere. The fuel pump 33, Fig. 3, comprises an impeller 72 attached to a shaft 57 by means of splines 75 and a cap screw 74. The shaft 57 is supported by ball bearings 58, 59 mounted in the walls of the driving gear casing 32. A pair of oil seal rings 64 are also provided. The fuel pump may be of the axial-flow or centrifugal type.

Abstract: 883,501. Nuclear reactors. BABCOCK & WILCOX Ltd. Sept. 21, 1960 [Sept. 23, 1959], No. 32391/59. Class 39(4) A nuclear reactor has vertical channels 12 up which coolant flows, the lower ends of the channels having restrictors or gags each comprising a sleeve removable through the channel and closed at its lower end by a member fixed relative to the core; coolant enters the sleeve through holes in its wall and flows out through the top of the sleeve, the wall of the sleeve above the holes being close to the surface of the channel. This arrangement is said to prevent lifting of the gag by the coolant when there are no fuel elements in the channel. In Fig. 2 coolant flows through channel 5 in a base plate, enters a space 38 outside the sleeve through ports 31, and enters the sleeve through holes 45. In Fig. 4 there are four channels 12 around each channel 5 ; coolant flows into a space above the base plate and then through holes 61 in the sleeve, which in this case is closed by a bearing plate 53. Outside the sleeve is a second sleeve 62 having holes 63; sleeve 62 can be rotated to open or close holes 61. In both embodiments the reactor core rests on ball bearings and the sleeve carries a fuel element support stem 20 which includes a shock absorber; alternatively the stem 20 could rest on the fixed member which closes the lower end of the sleeve.
