Title: Improvements in or relating to the separation of gas mixtures
IPC: C07C7/11
Filed: 1939-03-24
Abstract: 526,652. Separating gases by liquefaction. BRITISH OXYGEN CO., Ltd., and SCHUFTAN, P. M. March 24, 1939, No. 9281. [Class 8 (ii)] Gas mixture containing ethylene is cooled and purified in cold accumulators 3a, 3b alternately, the other accumulator being meanwhile cooled by the gas mixture after removal of the ethylene by rectification. The gas is fed to the accumulators through a cooler 2 by a booster 1, water being supplied by a pump 5, and is directed to one or other accumulator by a device 4, from which it passes through a washing &c. column 6 in contact with liquid ethylene, a precondenser 7, and an aftercondenser 9, cooled by the stripped effluent gas, and a main condenser 8 cooled by a jacket 10 of boiling methane, the crude ethylene deposited in the condenser 8 being delivered to the washer &c. 6. Ethylene from the base of the washer &c. 6 and methane from the jacket 10 and from a separator 12 which follows the condenser 9 are passed through a valve 21 and a pipe 36 respectively to a rectification column 22. The gas from the condenser 9 is slightly heated in a vessel 13, expanded in a turbine 14 and after cooling the condensers 9, 7 passed back to the outlet accumulator, the temperature in which can be varied during its cooling period by a byepass valve 15. Additional cooling of the outlet accumulator to compensate for the smaller amount of gas passing through it, is provided by drawing off and compressing in a compressor 16 a part of the gas from the cooler 2, the compressed gas being cooled, freed from carbon dioxide by an absorber 18, and further cooled in an interchanger 19 by effluent ethylene and less volatile products from the rectifier and by an expansion engine 20. Methane is delivered from the top of the rectifier and together with methane from the jacket 10 returned through an exchanger 28 to the refrigerating cycle comprising a four-stage compressor 26 with inter- and after-coolers and heating coils 29; 35 for the rectifier and 23 for the washer &c. 6, the methane then heating the vessel 13 before passing to the jacket 10 of the main condenser 8 ; apart of the methane is byepassed to the separator 12. The rectifier 22 may be replaced by a double column rectifier, methane being separated in the first column and the ethylene and heavier products further treated in the second column. At starting, the gas from the accumulator being cooled is returned to the booster 1, the carbon dioxide being first removed from the gas.

Title: Continuous combustion device
IPC: F23R3/26
Filed: 1971-04-15
Abstract: 1385903 Gas turbine engine combustion equipment UNITED AIRCRAFT OF CANADA Ltd 13 April 1972 [15 April 1971] 9530/71 Heading F1L The invention relates to combustion apparatus such as for a gas turbine engine in which baffle members are provided in the air-flow passage to control the amount of air passing to the primary and secondary combustion zones. The apparatus shown is of the reverse flow type and comprises an annular flame tube 221, 221a disposed within an annular air chamber defined between walls 215, 216, air entering the annular space 223 from inlet 226. A series of fuel injectors 231 supply fuel into the flame tube. A series of baffle members 243 are pivotally mounted at 244 on the outer wall 215 being controlled by linkage 247 connected to the engine throttle. At full load the baffles are disposed as indicated in full lines so that air passes both to the primary and secondary zones of the flame tube, but as power is reduced, the baffles move towards the closed position.as indicated in broken lines so that the flow of air to the primary zone is reduced and flow to the secondary zone is increased. Alternatively the baffles may be spring-loaded to the closed position and move to the open position against the loading of the springs as the pressure of the air increases. The object of the invention is to reduce the relative carbon monoxide and hydrocarbon emissions.

Title: Improvements in or relating to impact-wrenches
IPC: B25B21/02
Filed: 1956-03-28
Abstract: 796,975. Screwing-up nuts &c. ARO EQUIPMENT CORPORATION. March 28, 1956 [Dec. 5, 1955], No. 9676/56. Class 83 (3). In a portable nut-runner which delivers hammer-blows, a driver 28 is splined to a shaft 50 driven by a pneumatic-motor 49, and has a lug 30 engaging between cam-surfaces 26 on a hammer 22. The latter is located on a central pin 36 by an elongated slot 34, and in the radially-outward position of Fig. 5, engages a lug 16 on an anvil 14 shaped at 20 to fit a socket-wrench. The parts rotate anti-clockwise as shown in Fig. 5, to run a nut &c. on a bolt, and when the resistance to rotation increases, the cam-surfaces 26, 31 force the hammer 22 radially inwards, against centrifugal-force, so that lug 22<SP>1</SP> rides over the lug 16 and allows anvil 14 and the wrench to remain stationary. After passing over the lug 16, the hammer 22 is free to move outwards by centrifugal-force (Fig. 7, dotted lines), so that it is in position to deliver a hammer-blow to lug 16 at the end of the revolution, after which it rides over lug 16 again. The relative angles of surfaces 26, 31, 24 and slot 34 are such that the hammer is decelerated when moving inwards and accelerated when moving outwards to increase the force of the blows. The hammer and the cam-surfaces &c. are symmetrical so that the wrench may deliver hammer-blows to loosen a nut &c., on reverse rotation, after which continuous rotation unscrews the nut.

Title: Production of metal matrix composite material using barrier wall
Inventor: MAIKERU KEBUOOKU AGAJIYANIAN
IPC: C04B35/65
Filed: 1989-01-06
Abstract: A net shaped ceramic-reinforced aluminum matrix composite is formed by forming a permeable mass of ceramic material (10) with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy (20) with the permeable mass of ceramic material (10) in the presence of a gas comprising from about 10 to 100 % nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy (20) spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy (20) can be placed adjacent to a permeable bedding of ceramic material (10) having a barrier, and brought to the molten state, preferably to at least about 700 DEG C, in order to form the net shape aluminum matrix composite by infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.
