Abstract: 784,123. Moulding metal powder. BIRMINGHAM SMALL ARMS CO., Ltd. June 8, 1955 [June 8, 1954], No. 16703/54. Class 87(2). Metal powder is projected at high velocity into a die, and the resulting coherent compact is removed from the die and sintered. Fig. 1 illustrates the operation, 8 being-a nozzle which projects the powder to the bottom of a fourpart die 1, 2 enclosed in a casing 5. To prevent the powder particles bouncing, a thin layer 10 of metal powder may be initially spread on the bottom of the die. To vary the porosity at different parts of the article being made (e.g. a gas turbine blade) powders of different grain size may be successively projected into the die. Porosity may be achieved also by introducing with the metal powder thermosetting resin powder which is wholly or partly removed by the sintering. The resin may be cured by heat before sintering, and the article may be compressed hydrostatically before sintering. Destructible cores of cadmium, polystyrene or wax may be incorporated in the compact to form ducts in the article. The cores may be removed by the sintering or may be distilled off prior to the sintering. Fig. 5 shows an arrangement for forming through ducts, the cores 23 being secured at top and bottom and pulled straight by raising the crossbar 21 by means of nuts 25. The surplus ends of the cores are cut away when the compact has been completed. Specification 784,124 is referred to.

Abstract: 832,771. Gas-turbine plant. NAPIER & SON Ltd., D. May 16, 1957 [June 1, 1956], No. 16947/56. Class 110 (3). [Also in Groups XI and XII] An apparatus for igniting or sustaining combustion in a gas turbine or jet-propulsion engine comprises an auxiliary combustion chamber which communicates with the main combustion chamber or chambers of the engine, means being provided for supplying hydrogen peroxide to a catalytic decomposition chamber, the high temperature decomposition products being delivered together with an organic fuel to the auxiliary combustion chamber where spontaneous thermal ignition occurs the flame or products of combustion issuing into the main combustion chamber. The main combustion chamber of a gas-turbine engine is shown at 11 and comprises a flame tube 12 and main fuel injector 30, a torch igniter 10 in accordance with the invention being mounted on the combustion chamber so as to direct its flame into the flame tube 12. The torch igniter 10 comprises an auxiliary combustion chamber 14 which is combined with a catalytic decomposition chamber 13. Hydrogen peroxide admitted at 20 is decomposed in passing through the catalytic bed 13 into steam and oxygen at high temperature, the products discharging through the non-return valve 21, chamber 22 and annular inlet 23 into the auxiliary combustion chamber 14. Hydrocarbon fuel such as paraffin passes through the central duct 15 and non-return valve 16 through radial bores into the swirl chamber 17 and then issues through nozzle 18 into the auxiliary combustion chamber where spontaneous combustion occurs in the presence of the high temperature steam and oxygen, the combustion products issuing through outlet 28 into the flame tube 12. The hydrogen peroxide is contained in a reservoir 31 having a flexible partition 32 so that it may be pressurized by high-pressure gas such as nitrogen. The paraffin is tapped at 38 from the main engine fuel supply and passes through a valve 39 which is caused to open by the pressure of the decomposition products in the chamber 22 so that fuel is admitted to the auxiliary combustion chamber only after decomposition products are flowing thereto. In a second arrangement the paraffin fuel as well as the hydrogen peroxide is contained in a reservoir having a flexible partition and is pressurized by means of the high-pressure nitrogen from a storage bottle, the nitrogen supply to the paraffin fuel reservoir being controlled by a valve which is opened in dependence on the pressure of the decomposition products in the chamber 22. In the case of an engine having a plurality of combustion chambers, there may be a single decomposition chamber, decomposition products from which enter a ring manifold and thence to a separate auxiliary combustion chamber associated with each main combustion chamber.
