Patent GB-2031842-A (GB)
Title: A load rotating device
IPC: B66C13/08
Filed: 1979-09-12
Abstract: A load rotating device 1 has a rotary drive for operative connection with a load 3 via load connecting means and a power take-off. The device is suspended via one or more cables 2. It has been found that in consequence of the inertia of the load actuation of the device produces a torque or prestress in the cables which when the load is displaced through the rotary drive tends to rotate the load beyond its desired position. The present invention applies a torque or prestress to the cable in the opposite direction to the desired rotation, which subsequently initiates motion of the load in the desired direction. When the desired position for the load is reached, the rotary coupling between the load and the cable is disengaged whereby the torque or prestress in the cable can be released whilst the load remains at the desired position. In one embodiment the transmission between the rotary drive and load is de-coupled hydraulically and in a further embodiment decoupling is effected through an electromagnetic clutch. <IMAGE>

Title: Method of manufacturing articles of ceramic or metallic material
IPC: B28B3/00
Filed: 1980-05-02
Abstract: For manufacturing an article of a ceramic or metallic material by sintering and simultaneous isostatic pressing of a powder of the material, the powder is enclosed in an embedding material of glass which is made impermeable to gas before the isostatic pressing is carried out with a gaseous pressure medium. The powder is introduced into the mould cavity of a mould 10 made of glass powder, the mould cavity having a shape corresponding to that of the article to be manufactured, whereafter the mould is covered with glass 14 which, together with the mould, forms an embedding material for the powder. The powder and the embedding material are then located in a vessel 15, and the embedding material is transformed into a melt having a surface limited by the walls of the vessel, below which surface the powder in the mould cavity is located, before the pressure necessary for the isostatic pressing is applied to the melt with the gaseous pressure medium. Alternatively the tube through which the mould cavity is filled may be covered with a plate of glass rather than using the covering of glass 14. <IMAGE>

Title: Transmission ratio selecting mechanisms
IPC: F16H63/18
Filed: 1980-07-21
Abstract: A transmission ratio selecting mechanism including a ratio selector means (typically a hand lever), first and second ratio coupling members movable to select a number of ratios in the forward and revers drive directions of an associated transmission, and linkage means (65, 63, 64, 61, 62, 59, 57; 65, 63, 64, 70, 71, 68, 67) for moving the ratio coupling members in response to movement of the ratio selector means. The ratio selecting mechanism includes disconnecting means for disconnecting one of the ratio coupling members from the selector means (by axially displacing shaft 63 to bring splines 64 thereon out of engagement with gear sector 61) during selection of the reverse ratios of the transmission. During selection of any reverse ratio both the coupling members are initially moved in synchronism in response to movement of the selector means to complete the first part of the selection of the particular reverse ratio, the disconnecting means is then operated, and selection of the reverse ratio is completed by further movement of only one of the ratio coupling members in response to further movement of the selector means. The selector means is arranged to return the ratio coupling members to synchronism on movement of the selector means to disengage the reverse ratio. <IMAGE>

Title: Aircraft air conditioning system
IPC: B64D13/06
Filed: 1981-06-26
Abstract: An air cycle air conditioning system has an air expansion turbine 12 arranged for supplying a flow of turbine expanded air for conditioning a heat load 19. Water extracted at 16 from high pressure supply air upstream of the air expansion turbine 12 is injected into the coolant flow entry 17 of a heat exchanger 15 arranged for receiving the flow of turbine expanded air after this air has extracted heat from the heat load 19 e.g. a cabin. This enhances the cooling efficiency of the system by making use of the latent heat of evaporation of the extracted water when this water is returned to the system in a region where it provides a coolant function. The heat exchanger 15 cools high pressure supply air between the compressor 13 and turbine 12 but, in an alternative embodiment, the heat exchanger receiving injected water into the coolant flow entry is in heat exchange relationship with a fluid circulating in a separate loop to cool a further heat load. <IMAGE>
