Patent GB-2053106-A (GB)
Title: Vehicle having auxiliary drive mechanism
IPC: B60L50/16
Filed: 1979-07-09
Abstract: A motor vehicle has a forward mounted petrol engine (20) for driving the front wheels (27). The vehicle also comprises a rear mounted auxiliary motor (40) for driving a rear axle (34) on which rear wheels (37) are mounted. The rear axle (34) is coupled to the rear wheels (37) in such a way that drive can be transmitted from the rear axle (34) in the wheels (37), but the rear wheels (37) can overrun the rear axle (34) in both the forward and reverse directions. The auxiliary motor (40) is preferably an electric motor operable in both directions but alternatively it may be a hydraulic pump/motor. The auxiliary motor (40), which may be driven by the engine (20) either directly or through a battery (18), is manually actuable by the vehicle operator and is automatically disengageable upon reaching a predetermined speed. <IMAGE>

Title: Recovering aluminium from fly ash
IPC: C22B7/02
Filed: 1979-07-10
Abstract: Aluminum is recovered from fly ash by mixing the fly ash with calcium sulfate or a mixture of calcium sulfate with a material selected from the group consisting of calcium carbonate, magnesium sulfate, or magnesium carbonate, sintering the resultant mixture at a temperature which will convert the fly ash to a crystalline structure, and then leaching the aluminum from the sintered mass with an aqueous inorganic acid. The calcium sulphate may be derived from a dewatered sludge obtained by treating gaseous effluents of coal combustion with an aqueous slurry of lime or limestone to sorb SO2.

Title: Vehicle alarm and immobilising device
IPC: B60R25/10
Filed: 1981-07-23
Abstract: A vehicle alarm and immobilising device in which an arrangement of push-buttons located inside the vehicle is used to introduce a coded signal into the device to switch the device into its non-operating state. When the device is switched to its ready state, the vehicle is immobilised and, if a door is opened, the device changes to its activated state and an alarm will sound unless the coded signal is introduced into the device within a time interval. If the signal is introduced, the device changes to its non-operating state and, if the signal is not introduced, the alarm sounds and the vehicle remains immobilised. <IMAGE>

Patent GB-2087335-A (GB)
Title: Barge unloading system
IPC: B65G53/66
Filed: 1981-09-30
Abstract: A system and method for unloading dry, bulk, particulate material from a ship, barge or the like through a nozzle 20 alternately into first and second pressure vessels 10 and 11 and thereafter alternately transferring material from the pressure vessels into a storage container such as a silo. As one pressure vessel 10 is being filled, the material from the other pressure vessel 11 is being transferred into the silo. Thus the filling and emptying of the first pressure vessel 10 is 180 degrees out of phase relative to the filling and emptying of the second pressure vessel 11. Suction is used to draw the dry, bulk, particulate material from the ship into the pressure vessel. Thereafter, air is forced through the pressure vessel to transfer the material from the pressure vessel to the silo. Each pressure vessel is both filled and emptied from the bottom. The pressure vessels are physically close to the nozzle, resulting in a shorter, more efficient suction path, and the pressure vessels and nozzle are portable and may be lowered into the hold of a ship, barge or the like. <IMAGE>

Title: Process for the production of a tubular mould for continuous casting
Inventor: GRAVEMANN HORST
IPC: B23K15/00
Filed: 1983-03-25
Abstract: In the production of a tubular mould for the continuous casting, e.g. of steel, made of copper or a copper alloy, a flange (2) is attached to one end of a pipe (1) by electron beam welding. This method of welding produces a weld seam which, in contrast to welding methods previously used, is extremely narrow and which therefore does not appreciably affect the hardness of the pipe (1) where this has previously been hardened by cold working, and does not produce any appreciable distortion of the pipe (1) and/or flange (2). By suitable shaping of the flange (2) and/or the end of the pipe (1), welding can be effected either at the end face of the pipe, (as shown), or peripherally. <IMAGE>
