Abstract: 1319849 Gas turbine ducted fan engines DEFENCE SECRETARY OF STATE FOR 9 Nov 1971 [12 Nov 1970] 53815/70 Heading F1J The invention relates to a gas turbine ducted fan engine in which the pitch of the fan blades is variable whereby the fan blades may be moved to a reverse pitch so as to provide reverse thrust, the object of the invention being to ensure air flow to the engine compressor during reverse thrust operation. In Fig.1 the engine comprises a compressor 2 disposed so that its air inlet is rearwardly-facing, combustion equipment 3, an HP turbine 4 driving the compressor through shaft 5, and an LP turbine 6 driving fan 7 through shaft 8 and gearing 9. The pitch of the fan blades 7 is controllable by unit 20. The exhaust gases from the turbine 6 discharge radially outwardly through hollow structs 17 which extend across the fan duct 11, and discharge through a rearwardly-directed nozzle 19. The fan duct is defined by a cowl 10 which provides a forward air intake 12 and a rearward fan propulsion nozzle 14. A portion of the air discharged from the fan is directed by means of splitters 15 into the intake 16 of the compressor 2. In reverse thrust operation air is drawn in through the nozzle 14 and passes through fan duct 11 to the fan which discharges it forwardly through the intake 12; air also passes through the nozzle 14 to the intake 16 of the compressor. Flaps 21 on the nozzle 14 are opened in the reverse thrust mode so as to increase the area of the nozzle for air inflow. An auxiliary air inlet may be provided at 22 for use in the reverse thrust mode. A baffle 23 covered with sound absorbing material is disposed in the fan duct. In Fig. 3 (not shown) the engine comprises LP compressor 41 and HP compressor 43, combustion equipment 3, HP turbine 45 and LP turbine 42, the HP turbine driving the HP compressor through shaft 44, and the LP turbine driving the LP compressor also the fan 7 through shaft 8. The LP compressor is oversized so that part of the air compressed thereby discharges through duct 46 and is used either in a forward thrust nozzle 49 or for blown flaps of an aircraft in which the engine is mounted.

Title: Methods of and apparatus for die casting metals
IPC: B22D17/20
Filed: 1969-11-26
Abstract: 1336305 Pressure casting machines GKN GROUP SERVICES Ltd 18 Nov 1970 [26 Nov 1969] 57750/69 Heading B3F A pressure die casting apparatus has a cavity 12 defined by dies 10 and 11 separable from one another at a parting surface 13, a chamber 20 connected to the cavity 12 by a passage 14 extending along the parting surface, a passage 21 extending along the parting surface for feeding molten metal into the chamber 20, means 19 for closing the passage 21, and means 18 for pressurizing metal contained within the chamber 20 to cause it to flow into the cavity 12. The closure means 19 may consist of a rotatable block having channels 21a and 25 therein. In one position of the block these channels form continuations of the feed passage 21 and a vent 30 respectively; in a second position the channel 21a is out of alignment with the passage 21 which is thereby closed, and the channel 25 is in alignment with the passage 14 and thus puts the chamber 20 in communication with the cavity 12. The chamber 20 may be formed as a shot duct 15 having a piston 18 which, in addition to forcing metal into the cavity, also ejects solidified metal from the duct 15 when the dies are opened. A stop may be provided for determining the initial position of the piston 18 so that the volume of the shot duct does not substantially exceed that necessary to accommodate the quantity of metal required to form the product proper, a sprue and a "biscuit". The initial position of the piston may be adjustable. Molten metal, e.g. cast iron or steel, is introduced into the shot duct through the passage 21, the block 19 rotated into its said second position, and the metal forced into the cavity 12 by the piston 18. The dies, block 19, shot duct and piston may be made of steel, alloys of Mo, W or Ta; ceramic or cermet materials. The shot duet and cavity 12 may be evacuated and more than one cavity may be provided.

Title: Temperature control
IPC: B64D13/00
Filed: 1970-10-28
Abstract: 1339023 Fluid pressure servosystems NORMALAIR-GARRETT (HOLDINGS) Ltd 14 Oct 1971 [28 Oct 1970] 51131/70 Heading G3P In an engine anti-icing system Fig. 7, upon manual or automatic opening of solenoid valve 40, air from duct 5 flows via 43, 45 to the main port of vortex amplifier 16 and via 11 to a pressure chamber in valve 75 where the pressure aids spring 7 in tending to close the valve. Air is also admitted via 69, 70 to the main port of vortex amplifier 71 and via 72 to a further pressure chamber in the valve where the pressure tends to open the valve. With temperature-sensing vent valves 3, 58 and pressure-sensing vent valve 55 closed, a high back pressure is maintained at the control ports of the vortex amplifiers via 47, 73 and the valve 75 remains closed. If either of valves 3, 58 opens, the loss of back pressure at amplifier 16 causes the latter to depressurize line 11, allowing valve 75 to open and admit air to anti-icing cowling 74. If valve 55 should then open, the loss of back pressure at amplifier 71 causes the latter to depressurize line 72, allowing the valve to close. Movement of the valve 75 is fed back by cam 60 to valves 62, 65 controlling the back pressure at the respective amplifiers. Pressure switch 63 closes valve 40 upon excess air pressure in the supply duct. In a modified system, amplifier 71 is omitted and pressure responsive vent valve 55 controls amplifier 16, air being admitted to the forward pressure chamber of valve 75 downstream of valve 40. In a system controlling the temperature of fuel supplied to an engine at 2 Fig. 1, when sensor 3 opens to vent air at 4, the consequent loss of control pressure at amplifiers 17, 16 allows amplifier 16 to depressurize the spring chamber of valve 6, whereupon the latter is opened by inlet pressure at 5 to allow hot air from the engine to flow through heat exchanger 21 to heat the fuel. The control ports of the amplifiers may alternatively be supplied from upstream of the valve 6, and the main port of amplifier 17 may then be supplied from the same source. Amplifier 17 is omitted in a further embodiment and a manual over-ride solenoid vent valve is provided together with a feedbank restrictor responsive to movement of valve 6 to vary the control port pressure of the amplifier.
