IPC: G05D1/00
Filed: 1941-12-11
Abstract: 554,016. Valves. AUTOMATIC TELEPHONES & ELECTRIC CO., Ltd., and SAXBY, R. N. Dec. 11, 1941, No. 15981. [Class 135] A multiple-way valve device particularly adapted for controlling the supply of compressed air to compressed-air operated automatic pilot mechanism on aircraft comprises three lift valves selectively operated by a manually-actuated face cam. In the form shown in the Figures a cylindrical casing 19 is recessed on one face and fitted with a detachable recessed cover to provide a supply chamber 24 connected by a blind bore 40 and passage 41 with an inlet connection 10. Three rubber-faced lift valves 26, 27 housed in the chamber 24 have guide stems loosely engaging guides formed in chambers connected to outlet connections 11, 12, 13. The valves are opened against the action of springs 30 by a face cam 15 engaging balls 32, 33 engaging the guide spindles. The face cam has a kidney-shaped slot with chamfered ends and is rotatably mounted on a post 34 screwed into a socket in the casing. The cam plate is held in place by a spring 36 arranged between a washer 35 non-rotatably mounted on the post and a washer 37 secured in position by a nut 38. The actuating handle 14 is secured to the cam plate in one of six alternative positions by three bolts engaging three of six holes in the plate. An indicator plate is secured above the cam in a position to correspond with the setting of the handle: In the position shown in Fig. 5 the ball 32 is depressed to engage a rubber sealing washer 40 to prevent leakage and opens the valve 26 to admit compressed air to the gyroscope spin circuit. In a second position this valve is still held open and a second valve is opened to admit air to the automatic pilot circuit. In a third position these valves are closed and a third valve is opened to connect the supply chamber 24 to an outlet 11 leading back to the compressor, and fitted a restriction 42. When the valves are closed the balls move away from the sealing washers to permit any air remaining in the outlet conduits to leak away. The cam has a series of peripheral notches adapted to co-operate with a spring- pressed ball locking catch.

Title: Process for preparing thermoplastic (e.g. polyethylene) film
IPC: B29C48/03
Filed: 1960-05-09
Abstract: 891,652. Films. PHILLIPS PETROLEUM CO. May 9, 1960, [May 20, 1959], No. 16271/60. Class 2(2) Films are made by extruding molten organic thermoplastic material through a slot die and quenching the resulting film in a bath of quench liquid which is kept free of suspended solids. The quench liquid is preferably water, maintained at 135-160F. but if a higher boiling bath is required, ethylene glycol or the polyethylene glycols, e.g. diethylene glycol, and/or their lower alkyl ethers, can be used. Quench liquid may be kept free of suspended solids by using a filter having a pore size of 5-20 microns, especially a wool filter having a pore size of 10 microns. Transparent polyethylene film may be made by extrusion of high density polyethylene into an aqueous bath which is continuously filtered. In a preferred method, the quench liquid is kept at a given temperature by withdrawing a stream thereof, subjecting it to heat exchange and returning the stream to the bath via a filter. As shown, granular thermoplastic material supplied to hopper 8 of the extruder 2, is melted in the barrel 3, which is fitted with a heating jacket 4 for supply of a heat transfer fluid via inlet 5 and outlet 6, and conveyed via passage 9 to the heated cavity 11 of the slot extrusion die 10. Film is extruded from slot 14, quenched in bath 15 and withdrawn via rolls 25 and 26. A portion of the quench liquid is continuously withdrawn through conduit 22, make-up liquid being added at 22A, and passed through the heat exchanger 21. The quantity of heat transfer fluid supplied to 21 through conduit 20 is regulated by motor valve 19, which is controlled by the temperature recorder-controller 18 and thermostatic element 17, immersed in the quench bath. Thus the contents of conduit 22 are heated to a predetermined temperature. In a modification, electrical heating means are used at 21, thermostatically controlled at that point. The heated quench liquid then passes through filter 23 and is returned to the bath. Specification 891,651 is referred to.
