Title: Looms
IPC: D03D49/02
Filed: 1971-04-19
Abstract: 1348576 Looms SULZER BROS Ltd 19 April 1971 [9 April 1970] 26363/71 Heading D1E In a loom, the cloth roll 76 is mounted above the loom frame on a structure providing inclined parallel tracks 25 for guiding the roll on and off the loom, and means for raising and lowering the roll. Fabric 95, after being taken up by the sand roll 22 is guided by members 24, 96 and 97 under a gangway 89 for the operator and over a further member 98 and rolls 28 and 45 to the cloth roll 77. Fabric is taken up by rotating' one or both of the rolls 34, 37 on which the cloth roll 77 is supported by a chain drive (108), Fig. 5 (not shown) which is driven by sprocket 104 freely mounted on the sand roll shaft 99 and rotated by a spring loaded friction clutch 102 mounted on the shaft. The means for raising and lowering the cloth roll comprises chains 81 connected to the ends of the cloth beam 76 and moved in either direction by a handoperated crank handle 63. One of the rolls 37 on which the cloth roll 77 is supported may be lowered to 37' by rotating a handle 43 to allow the cloth roll to roll off it.

Title: Treatment of nickel-bearing ammonium carbonate leach liquors
IPC: C01G3/12
Filed: 1974-06-14
Abstract: 1439100 Nickel recovery SHERRITT GORDON MINES Ltd 14 June 1974 [5 July 1973] 26392/74 Heading C1A Nickel is recovered in elemental form from a nickel-containing aqueous ammoniacal ammonium carbonate solution by a process which comprises: adjusting the composition of the solution so that it contains at least 1À5 moles of ammonium sulphate per mole of contained nickel; heating the so-adjusted solution to expel carbon dioxide and ammonia and produce a nickel diammine sulphate solution; recovering elemental nickel from said nickel diammine sulphate solution (e.g. by reduction with hydrogen), so forming at least one mole of ammonium sulphate in the end solution per mole of recovered nickel; and recycling the end solution to supply at least a part of the sulphate requirement of the composition adjustment step. Various modifications of the process are described which include steps for the elimination of impurities; e.g. iron, manganese and aluminium may be converted to their hydroxides and carbonates in an oxidative step which also converts sulphur-containing impurities to sulphate ion; copper and cobalt may be precipitated as their sulphides; and build-up of chloride ion in the solution may be prevented by further heating of the nickel diammine sulphate solution until nickel ammonium sulphate is precipitated, followed by separation of the precipitate from the chloride-contaminated solution and dissolution of the precipitate in anammonical solution to form a nickel diammine sulphate solution, which may then be reduced with hydrogen.

IPC: H05B3/00
Filed: 1960-07-29
Abstract: 916,586. Incinerators; electric air heaters. GENERAL ELECTRIC CO. Ltd. July 28, 1961 [July 29, 1960], No. 26502/60. Classes 39 (3) and 126. An incinerator for burning soiled bandages, waste paper &c., has a combustion chamber provided with means for causing hot air to flow to initial combustion of material in the chamber. This combustion chamber 1 has a metal mesh grate 2 above an ash drawer 4, and is provided with nozzles 7, 8 in one side wall, and 9 in the opposite side wall, directing intersecting jets of hot air to the centre of the grate. Each nozzle is supplied by a vertical tube 10, 11, 12, comprising a pair of concentric tubes 13 and 14 of refractory material, the inner tube 13 being a former for an electric heater element 15 of cross-spiral formation. A fan type blower supplies air to these heater tubes. A flue 16, Fig. 5, from the upper end of chamber 1 has a horizontal part 17 leading to a vertical part 18, the latter extending below part 17 to form a well 19 with an ash drawer 20. A grid 21 solidly connected with a baffle 22 is mounted pivotally in the flue. Normally, grid 21 engages the underside of a flange 23, and the baffle 22 seals well 19. When the access door 3 of the combustion chamber is opened to introduce waste material, a linkage causes grid 21 to fall on to a flange 24, knocking off ash into well 19, which is opened by the simultaneous downward movement of baffle 22. The opening of door 3 also shuts off blower and heaters, which are automatically switched on when the door is closed. Alternatively, the blower remains running, the opening of door 3 causing a flap valve to divert some or all of the air from the heaters to a nozzle in the flue to provide suction in the combustion chamber. The grid and baffle arrangement in the flue may be replaced by a settling chamber, water wash, cyclone particle extractor, or by a large simple flue of 6-inch to 9-inch diameter.

Title: Improvements relating to fuel supply systems for gas turbine engines
Inventor: TYLER STANLEY RALPH
IPC: F02C7/22
Filed: 1952-10-27
Abstract: 740,457. Gas turbine plant. DOWTY EQUIPMENT, Ltd. Oct. 27, 1953 [Oct. 27, 1952], No. 26970/52. Class 110(3) [Also in Group XXIX] In a liquid fuel supply system for gas turbine engines of the kind having an engine-driven pump 3 of fixed displacement supplying burners 7 of the spill type and a servo-controlled throttle valve 11 in the spill line 8, the vent or leak-off valve 33 controlling the throttle valve 11 is operated by a spring-loaded pressure responsive device 25 exposed to the output pressure of a pressure proportioning device having an input connection 17 with the burner supply line, an output connection 24 to the pressure-responsive device, and a return connection 23 to the spill line 8, a variable restrictor being provided to vary the fractional proportion of output pressure to input pressure and thereby determine the degree of opening of the vent valve 33 and of throttle valve 11 and hence the governed speed of the engine. As shown the pump 3 draws its supply from a tank 1 and supplies the burners 7 through pipes 4, 6 excess fuel being returned by the spill pipe 8 to the valve 11 and hence by a pipe 10 to the tank and the pump inlet. In the inoperative condition and at starting, the pipe 6 is blocked by the land 13 of a control valve 5 so that fuel is circulated back to the pump inlet by a pipe 14, the latter being closed by a land 15 when the valve is moved to the right to open the pipe 6. The valve 5 slides in a sleeve 22 and the input and output connections of 17, 24 open into this sleeve between the land 13 and a further land 18, controlling a series of orifices 19, 20, 21 leading to the return connection 23. The input connection 17 has a normally-fixed restrictor 16. As more of the orifices 19, 20, 21 are exposed the pressure in the output connection 24 drops and the vent valve 33 tends to close. The pressure-responsive device 25 comprises a bellows 26 exposed internally to the output pressure and externally to the pressure in the spill line 8. The bellows is loaded by an adjustable spring 30 and operates the valve 33 through a thrust rod 32. The throttle valve 11 is operated by a servo-device comprising a spring-loaded diaphragm 38 connected directly to the fuel supply pipe 4 on one side and on the other 'side to the vent opening 34 controlled by the valve 33, the two sides of the diaphragm being connected by a restricted orifice 40. The minimum idling speed is determined by the spring 30 and the maximum governed speed by the adjustment of the restrictor 16. The orifices 19, 20, 21 may be opened step by step by a remotely controlled constant speed motor. The orifices may be replaced by a single slut. According to the Provisional Specification the restrictor 16 may be biassed by a capsule or the like responsive to engine intake pressure to compensate for the effect of altitude and ram pressure on the governed engine speed
