Title: Improvements in or relating to aircraft jet engine cooling system
Inventor: SON LOYAL A WILLIAM
IPC: F02K1/82
Filed: 1952-12-29
Abstract: 723,406. Gas-turbine jet-propulsion engines. NORTHROP AIRCRAFT, Inc. Dec. 29, 1952, No. 32835/52. Class 110 (3). [Also in Group XXXIII] An aircraft having a gas-turbine jet-propulsion engine having a shroud surrounding at least a portion of the engine through which cooling air is passed from the engine inlet duct to the jet-propulsion nozzle which acts as an ejector, has means for admitting cooling air at atmospheric pressure to the shroud when both the inlet duct and the outlet in the jet-propulsion nozzle are at negative pressure. Air is supplied to the intake 11 of a gas-turbine jet-propulsion engine through a short inlet duct 10. The front end of the intake 11 is spaced from the rear end of the duct 10 by spacers 15 which form an annular inlet to the duct 17. A shroud 18 cantilevered from a flange 19 on the engine casing extends rearwardly around the combustion and turbine section 21 and tail pipe section 22 to an opening 6 which is beyond the rear of the tail pipe 22. The shroud 18 forms a cooling space 17a to which air is led by a duct 16a having flame traps 20. With the engine running the jet of hot gases passing through the propulsion nozzle 24 will cause a negative pressure to be developed at the rear end of the shroud and air to be drawn through the passages 17, 17a. When the airplane is stationary with the engine running, a negative pressure is also developed in the inlet duct 10. A flap valve 31, Fig. 4, at the inlet duct then opens and air flows through the duct 16a and then divides; part flows forwardly through the passage 17 to the inlet duct 10 and part flows rearwarldy through the duct 17a towards the jet-propulsion nozzle. When the aircraft is in flight, a positive ram pressure exists in the duct 10, and a negative pressure at the rear end of the shroud. The cooling air will then flow as shown in Fig. 2 from the duct 10, passage 17, inlet duct 16a and passage 17a to the propulsion nozzle. To cause the flap valve 31 to open and close under the correct conditions, the duct 16a has its inlet 30 arranged in the engine casing 3 at a position where the pressure is zero when the aircraft is stationary and negative when the aircraft is in flight. The valve 31 is preferably formed of impregnated cloth attached to a flush plate 33 but it may be formed by a hinged metal door. With the arrangement described, the normal heat-insulating blanket may be replaced by a polished stainless-steel heat shield 35 supported from the shroud 18 by members 36. A baffle 39 is provided to equalize the air flow around the engine. Specification 591,736 is referred to.

P., Sandybank, Banks Road, Sandbanks, Bournemouth. Nov. 18, 1933, No. 32902. Divided on 413,744. [Class 7 (ii).] Exhaust gases are passed through or over two or more catalysts in series, or are wholly or partially byepassed around the whole or part of one or more of said catalysts. The gases pass into a pipe 3 from the cylinders through apertures 2 separated by partitions 7 of wire mesh, pumice, or asbestos which carry a catalyst operative at high temperatures, such as iron vanadate, and are mixed with air drawn in past a non-return valve 9 or forced in by a pump. A chamber 4 is mounted over a projecting end of the pipe 3, and a ringed valve 5 located at the end of the pipe causes the gases to pass through perforations and through or around carriers 8 of asbestos mat impregnated with a catalyst operative at low temperatures, such as mixed copper and manganese oxide promoted with cerium oxide, before being discharged through the pipe 6. The valve 5 may be spring or gravity controlled so that it opens when the pressure or velocity of the gases rises and enables them to pass directly from the pipe 3 to the pipe 6. Alternatively, the valve may be opened as the throttle opens, or be controlled by an engine governor or manually. In a modified construction, both types of catalyst are mounted in the chamber 4 and the valve 5 then allows the gases to pass or byepass through both types of catalyst. Specification 413,744 is referred to.

Title: Improvements in or relating to two-way communication networks
IPC: H04B3/20
Filed: 1961-09-14
Abstract: 916,543. Two-way transmission systems. WESTERN ELECTRIC CO. Inc. Sept. 14, 1961 [Sept. 29, 1960], No. 33049/61. Class 40 (4). A two-way communication network comprises in each path, means for disabling the other path, said means being responsive to signals above one threshold with one time delay and signals above a higher threshold with a larger time delay. The invention is described in relation to a system for phototransmission over circuits liable to cross-talk from neighbouring speech conductors and also to return echoes. The time delays used are therefore large, e.g. 2 and 4 sees. respectively. As shown, west-east signals after amplification are fed to rectifier 21 and a circuit 25 having a threshold of - 40 db. (reference the maximum likely signal) and if this is exceeded then after a time delay of 4 seconds relay RY3 operates. The signal is also applied to a 20 db. pad 19 to a circuit 27 having a threshold of - 40 db. and a two second delay. Thus, if the signal is above the - 20 db. level RY5 operates. Each of relays RY3, RY5 operates RY7 which disables the east-west path and also a circuit similar to the above operative to east-west signals to disable the west-east path. This circuit will operate satisfactorily for echoes from the east terminal 20 db. (or better) down on the westeast signal. Thus, for outgoing signals of - 40 to - 20 db. circuit 25 operates RY3 and RY7 to disable the east-west path whose timing circuits 24, 26 cannot operate to the echo which is between - 40 and - 60 db. For outgoing signals between - 20 and 0 db. the echo signal is between - 40 and - 20 bb. so that the four-second timing circuit 24 would start to operate. However, the two-second timing circuit 27 would operate to disconnect, at RY7, the slow timing circuit 26, which is thus rendered ineffective. The timing circuits each consist of a two-stage transistor amplifier (whose first stage is provided with a threshold voltage) operating a relay which connects up a condenser-resistance time constant circuit in the emitter-base circuit of a further transistor whose output operates a relay.
