Filed: 1976-09-22
Abstract: 1517256 Fuel gas manufacture SIEMENS AG 22 Sept 1976 [26 Sept 1975] 39389/76 Heading C5E Fuel gas may be prepared in a reaction chamber such as shown in Fig. 2 from a mixture of a liquid hydrocarbon and a gas comprising free oxygen e.g. air supplied via lines 18 by (a) electrically heating part of the catalytic material 14 contained in the chamber 10, (b) after completion of this heating supplying the mixture relatively rich in oxygen to the heated part of catalytic material, so that exothermic conversion of the mixture takes place without flaming, the conversion causing heating of further catalytic material and the product of the conversion being the fuel gas and (c) after sufficient heating of further catalytic material, supplying the mixture poor in oxygen relative to the mixture supplied in step (b) to substantially the whole catalytic material so as to provide a continuous output of fuel gas. The electrical heating coil 2 heats a part of the catalytic material in the vicinity of gas outlet 13 to a starting temperature indicated by thermo-detector 4. With the heating coil switched off the hydrocarbon/air mixture is supplied to the catalytic material by way of-selector valve 20 and auxiliary supply line 3 and the prepared fuel gas passes through the outlet 13 and plug 25. The exothermic reaction heats the remainder of the catalytic material to a temperature indicated by thermodetector 5. The hydrocarbon air/mixture is rerouted by the selector valve 20 to the inlet 12 from where it passes through the heated catalytic material to produce fuel gas which exits through outlet 13. If the temperature drops below the operating temperature, heating spark plug 15 may be actuated. Preferred catalytic materials are constituted by porous and hollow spherical refractory bodies or by inorganic fibres. The whole apparatus may be coupled to an internal combustion engine.

IPC: H02K9/10
Filed: 1929-12-24
Abstract: 334,473. Akt.-Ges. Brown, Boveri, et Cie. Dec. 24, 1928, [Convention date]. Heating machines whilst inoperative; dynamos, cooling. - An electric turbo-generator is maintained at the working temperature whilst inoperative so as to be ready to take on full load by supplying heat from an outside source by means of a gaseous heat carrier, such as air, which is kept continuously in circulation. Fig. 3 shows a turbo-generator 9 embodying the usual closed cooling system comprising inlet ducts 10, 11, outlet duct 12, a cooler 15 and a blower 14 driven by a motor 13. When the generator is out of operation, the cooler may be employed as a heater by shutting off the cold water valves 16, 17 and opening steam or hot water valves 18, 19. All the valves may be regulated by a thermostat to maintain a constant working temperature whether the machine be in or out of operation. The losses in the blower may supply the necessary heat, the rate of generation of heat being regulated by a thermostat which controls the speed of the driving motor. Instead of using the blower in the ordinary cooling system, a separate auxiliary installation may be provided. An electric resistance 22 in the main cooling ducts may supply the necessary heat or a subsidiary system comprising ducts 24, 25, a blower 27 driven by a steam turbine 26, and an electric heater 23 may be used. The source of heat may be kept in operation continuously. Regulation may be effected by the use of a thermostat 30 built into a pipe 31 in the subsidiary system. The thermostat controls contacts 37 in the circuit of the heating element 23. The turbine 26 also may be controlled by the thermostat, and where a steam heater is used instead of the resistance 23, it may be supplied from the exhaust of the turbine and regulated by a throttle 38. Fig. 4 shows the invention applied to a turbogenerator 45 driven by a steam turbine which also is required to be kept hot whilst inoperative. A common source of heat 40 is employed supplying the turbine through pipes 42 and 43 and blower 44 and supplying the generator through pipes 46, 47 and valves 49, 50. For adjusting the temperature-volume ratios of the two heat carriers, an auxiliary blower 51 with valves 52, 53 may be provided. In the case of very long rotors, they should be rotated slowly while heat is being supplied.

Abstract: 1,067,579. Injection moulding footwear. BRITISH UNITED SHOE MACHINERY CO. Ltd. Oct. 16, 1963 [Oct. 17, 1962], No. 40750/63. Heading B5A. In a machine for injection moulding shoes comprising a plurality of mould assemblies mounted on a conveyer for movement from an injection station through a plurality of: idle stations to an unloading station and back to the injection station, wherein each mould assembly comprises side mould members 58, (60) (Fig. 1, not shown) movable relative to a fixed sole mould member 62, a mould-opening device moves the side members (60) to an open position during movement of an assembly to the unloading station and a mould closing device moves the members 58, (60) to their closed : position before movement away from the unloading station. The machine described is similar to that in Specification 930,840, the conveyer comprising a pair of chains 20, 22. The mould closing device comprises a fluid pressure actuated piston 104 which engages an arm (110) (Fig. 5, not shown) on a shaft (78) to move this shaft clockwise and also a second shaft (80) (Fig. 1) to which it is connected by a link (100). The shafts (78, 80) are connected to the side mould members 58, (60) by toggle linkages. The mould opening device comprises a cam member (114) (Fig. 6, not shown) engaged by a cam roll carried by the shaft (78). The mould closing device is operated by means of a microswitch when an arm 132 carrying a foot form 120 is pivoted about a shaft 134 to its horizontal inoperative position (Fig. 3, riot shown). Downward movement of the arm 132 is braked by an arm 182 urged to the position shown in Fig. 2 by a torsion spring 190. The arm 132 is held in raised -position by a pivoted latch arm 160. The foot form 120 is mounted on a platen 126 pivoted at 130 to the arm 132. A link 154 pivoted to the platen 126 at 140 has a slot 152 engaged by a shaft 150 mounted on the arm 132. During swinging of the arm 132 downwardly the platen 126 swings in the reverse direction relatively to the arm 132 so that the foot form moves initially without angular movement relative to the mould members. When the arm 132 is in the unloading position (Fig. 3, not shown) the link 154 pivots to a position in which it locks the platen 126 and foot form in position. The injection cylinder (208) (Fig. 7, not shown) is supplied with plastic material by a plasticizing screw (226) the rotation of which is stopped by means of a microswitch (256) operated by the injection piston (210) when the cylinder (208) is full. If the plasticizer fails to stop, the material escapes through a groove (254) in the piston (210). The screw (226) has a threaded portion (228) providing a helical groove which decreases in depth from the receiving end to its mid point. Material is fed to the screw in the form of a tape which is cut into short lengths by helical teeth (234) which co-operate with a stationary cutter (240) (Fig. 8, not shown).
