Abstract: 1363590 Low pressure casting apparatus SOC DE VENTE DE L'ALUMINIUM PECHINEY 1 Aug 1972 [2 Aug 1971] 35944/72 Heading B3F  An apparatus for casting thin-walled articles comprises a mould 3 whose upper end can be vented to the atmosphere, a low pressure casting furnace 1 having a crucible 12 therein, a compression chamber 2 comprising two cavities 22 and 23 one of which is connected to a pipe 25, and a valve 4 having a movable member 46 that is capable of closing all the ports of the valve or of connecting the inside of the furnace to (a) a source of compressed gas, (b) the pipe 25 or (c) the atmosphere. At the beginning of a casting cycle all the ports of the valve are closed. The member 46 is then rotated to a position in which a cut-out portion 47 places pipes 41 and 42 in communication with each other. This causes a compressed gas to pass into the furnace 1 and force the metal contained in the crucible 12 into the mould, the air present in the latter being discharged through vents 35 which are then closed. After a thin layer 32 of metal has solidified, Fig. 8 (not shown), pipes 25 and 42 are brought into communication with each other to permit the molten metal in the mould to flow back to the crucible 12. The pressure within the apparatus is then brought to atmospheric by connecting pipes 25 and 44 to pipe 45. The mould may consist of a plurality of parts some of which are provided with coolant conduits, Fig. 12 (not shown). To prevent metal from passing into the pipe 25 in the event of a leak in the valve 4, a safety device is provided which stops the casting cycle if the metal contacts a pair of conductors (27) projecting into the top of the cavity 23. The compression chamber 2 may be heated. The apparatus may be used to cast radiator elements, Figs. 10 to 12 (not shown).

The paper may be metallized with aluminium, and molten copper is sprayed on the ends from a spray gun, or zinc-coated paper may be sprayed with zinc. The ends of the rolls may be masked along a diameter during spraying, so that the condenser may be impregnated with fluid through the unsprayed portions.

In apparatus for drying tobacco, the tobacco passes through a rotary drum 1 from an inlet hopper 17 to an outlet opening 19 and is dried both by heated air from a pipe 29 and also by steam heated coils 10 to which the steam is supplied through a constant pressure valve 62 through a restricting valve 61 intermediate a steam pressure measuring device 60 and the valve 62 whereby the drying process leads to pressure changes in the coils as sensed by the device 60 which automatically adjusts the temperature of the air entering through the pipe 29. Automatic adjustment is achieved by the device 60 which is connected to a regulator 66 operating via a device 32, a flap valve 9 controlling the entry of cool air into the hot air feed pipe 29. Modifications of the control system are illustrated and described, e.g. two heating coil systems may be provided, the temperature of one being adjusted in response to the pressure changes in the other steam heated coil.

[Class 78 (v).] In a doubleacting hoist in which two chains carrying load hooks are wound in opposite directions on a common drum and in which a friction driving pulley on the drum shaft is adapted to be moved from a central automatically-braked position into engagement with one or the other of a pair of oppositely-disposed friction wheels, for driving it in opposite directions, a special mounting of the drum shaft is used to facilitate the movement. Fig. 1 screws the friction wheel C on the drum shaft adapted to be moved out of contact with the adjustable brake block E into engagement with one or other of the belt-driven friction wheels D, D<1>. The drum shaft b, which is carried at one end by a universal joint, is carried at the driving end by a lever F which rests upon two fulcrum points G, G<1> Fig. 4. Swinging of this lever to the left or right of the mid-position, through the agency of the pull-cords l<5>, l<6> and the links l<3>, L, in order to engage either of the driving-wheels, causes a lifting of the end of the shaft b by changing the fulcrum which is sufficient to remove the brake. By means of the cords, the gearing can be maintained in an intermediate position to give a free-wheel barrel.
