Title: Improvements in the treatment of ores, wastes, oxides, metals and other substances
IPC: C22B4/00
Filed: 1926-12-03
Abstract: 265,548. Fourment, M. Feb. 2, 1926, [Convention date]. Induction furnaces.- Ores, waste metal &c., are treated in a furnace consisting of a series of carbon crucibles provided with induction windings in which circulate currents of from 500 to 50,000 periods per second. The crucibles 3 - - 6 are arranged vertically as shown, the bottoms of the upper ones being formed as gutters surrounding the charging hopper 2 with a space for the passage of vapours. The crucibles have separate windings 12 - - 15 and the upper ones may be provided with cooling devices. The material to be treated is fed through the hopper 2 into the bottom crucible 3 which is strongly heated and the upper crucibles are maintained at temperatures suitable to condense the different vapours given off. The crucibles are provided with heated discharge openings 7 - - 10 and the lowermost with a heated overflow 11. In this apparatus powdered metals such as lead, tin, aluminium, zinc &c. may be prepared as sublimates; the constituents of complex ores, such as those of lead and zinc, or of waste metals, may be separated; carborundum may be prepared from carbon and sand.

Title: Improvements in or relating to method of making propeller blades
IPC: B21H7/16
Filed: 1953-11-06
Abstract: 739,141. Making propeller blades. UNITED AIRCRAFT CORPORATION. Nov. 6, 1953 [Dec. 30, 1952], No. 30746/53. Class 83 (2). A method of making a propeller blade blank comprises heating a metal tube and shaping the heated tube which is supported internally into a tube having two diametrically-opposed exterior fins extending longitudinally thereof, said fins having a greater thickness than the tube wall thickness, cold rolling said finned tube while internally supported to elongate the tube and reduce the fin and wall thickness and taper the finned tube. A forged cylindrical billet is heated, pierced to form a tube and then extruded over a mandrel to provide a blank 14 having an elliptical aperture 16 and external longitudinal fins 20. The unextruded shank 22 of the blank may be machined or extruded later to the same contour as the blank but having a greater wall and fin thickness. After heat treatment the blank is cold rolled by a pair of oscillating dies co-operating with a tapered mandrel to shape and reduce the thickness of the blank wall and the finned portions as shown in Fig. 12. The shaping and thinning is effected progressively in three rolling operations between which the blank is annealed. After rolling, the elliptical shank 24 is machined to a uniform wall thickness, the fins being machined off, after which the shank is formed into a circular cross-section 38 by a hot pressing and expanding operation followed by a heat treatment. Next the shank is swaged to form a thickened section 40 of smaller diameter. Finally, the shank is machined as indicated at 44, Fig. 18, and the blank is cold flattened to form a blade 42 during which operation lead may be flowed into the regions of the reverse bends to assist in holding the wall in the desired shape. Alternatively, the interior of the blade may be subjected to fluid pressure during the flattening operation. After the flattening, the leading and trailing edges are ground to airfoil shape, the blade tip 45 is closed by seam welding and the blade is heated and twisted in dies to its final form while the interior of the blade is filled with nitrogen under pressure. After tempering, the blade is filled with a low density synthetic sponge and the exterior is vapour blasted and polished. Alternatively, a push bench process may take the place of the extruding operation prior to cold rolling the blank wherein a forged ellipticallyshaped billet is heated, partly pierced and then passed through a series of rolls which form the exterior finned contour of the blank a mandrel being inserted in the blank to form the inside contour. The solid end of the blank prior to the push bench operation is machined as shown at 54 in Fig. 27 to enable it to be gripped in the push bench and this solid end is cut off before the cold rolling operation.

Abstract: 1,244,891. Vapour generators. E. S. MILIARAS. 23 June, 1969 [28 June, 1968], No. 31622/69. Heading F4A. A fossil fuel fired vapour generating system comprises a furnace section 6, a super-heating section 10a, and an economizer section 12, with a flue gas flow path 7 passing through the sections, and a secondary device 13 which can supply supplementary hot gases to increase the heat input to the feedwater at the economizer and so increase the vapour energy output of the system. At peak demand times additional fuel is introduced through a burner 14 and burned in a chamber 13, combustion air being provided by a fan 15. A damper 17 is closed when the increased vapour generator output feature is not required. Alternatively the additional combustion may take place in the space directly upstream of the economizer in the flow gas path 7, the fuel being introduced through a burner 16. The invention is shown in use with a highpressure turbine 30, a low-pressure turbine 31 driving an electrical generator 32, a condenser 34, closed feedwater heaters 35 supplied with steam through valves 37, a deaerating heater 36 and a demand sensor 38. When this sensor detects an increase in electrical demand it sends signals to close valves 37 thus increasing steam flow through the turbines, opens damper 17, operates fan 15 and fires additional fuel in burner 14 thus increasing heat input to the economizer and so allows increased electrical output for short periods to meet peak demand. In another embodiment, Fig. 2 (not shown), the secondary device has a second supplementary duct (21) downstream of the economizer to permit recirculation of the combustion gases. In a further embodiment, Fig. 3 (not shown), a second supplementary duct (25) is located downstream of the economizer and a third supplementary duct (25a) on the furnace 6 side of the system.
