Title: Improvements in or relating to electric contactors
IPC: H01H3/60
Filed: 1952-06-02
Abstract: 742,926. Dashpots. GENERAL ELECTRIC CO., Ltd., and LONDON, C. A. June 5, 1953 [June 2, 1952], No. 14252/52. Class 108 (3). [Also in Group XXXVII] A dashpot comprises an oil-filled container 20 which is adjustably mounted by a threaded spigot 21, the top of the container being closed by a member 22 having a bore 24 slidably receiving the plunger 19. A spring 28 acts between the enlarged plunger end 25 and a plug 26 closing the end of the bore 24, a ball 30 normally closing a hole 29 in the plug. A passage 31 leads from the bore 24 to an adjustable needle valve 32 and is then vented into the container 20 through a port 36. A passage 37 ensures that any oil which rises above the plunger end 25 flows back into the container when the plunger is returned by the spring 28. Downward movement of the plunger 19 is thus controlled by the needle valve 32, the upward movement being free due to the ball valve 30.

Title: Process for separating propylene from a polypropylene-liquid propylene slurry
IPC: C08F110/06
Filed: 1964-04-07
Abstract: Polypropylene is separated from a slurry of polypropylene in liquid propylene, by feeding the slurry containing 50-60% of polypropylene, under at least autogenous pressure to a cyclone separator maintained at substantially atmospheric pressure and removing by flashing, all or substantially all, the propylene monomer. The polypropylene is obtained by bulk polymerization in the presence of a "low-pressure" catalyst such as T1Cl3 co-crystallized with AlCl3, and activated with (C2H5)2AlCl.  The catalyst residues are removed from the polypropylene by conventional techniques such as isopropanol containing HCl.  The removed monomer is generally compressed, condensed, and recycled to the polymerization zone. The whole process, i.e. preparation of polymer, recovery, and purification is usually effected in a continuous manner.  The Specification includes a flow diagram of a continuous method for carrying out the process.

Abstract: 804,597. Cementation. DORTMUND-HORDER HUTTENUNION A.G. May 9, 1956 [May 10, 1955], No. 14437/56. Class 72 An apparatus for carburizing or nitriding the surface of a metal body in a gas under low pressure in the presence of a glow discharge comprises a vacuum chamber in which there is a support for the body, an anode, a cathode for connection to the body and a shield of electrically insulating material adjacent the support with a narrow gap between it and a cathode part to which the discharge extends for restricting the extent of the discharge, the shield being entirely within the chamber, and spaced from the wall thereof. The apparatus is shown generally in Fig. 1 and comprises vacuum chamber 10 inside which are mounted tubes 32 the inside walls of which are to be treated. The ends of tubes 32 are fixed in supporting devices 34 held in holes 27, 29 in walls 16, 17. Metal rods or tubes 35 are placed coaxially inside tubes 32 and held in insulating tubes 37, 38 so that in operation of the apparatus a glow discharge ignites between rods or tubes 35 as anodes and the inner surface of tubes 32 as cathodes, the chamber 10 being fed with methane for carburizing or ammonia for nitriding. As shown in Fig. 3, supporting device 34 comprises metal cylinder 64, the flanges 65 of which fit into hole 27 of wall 16 and the bottom part 66 of which serves as a stop for the upper end of tube 32; and sleeve 67 of insulating material. In operation, the glow discharge spreads to region 76 between rod or tube 35 and cylinder 64, but is prevented from spreading further by sleeve 67 in combination with narrow annular gap 74.

Title: Lubricated valve
IPC: F16K5/22
Filed: 1944-07-31
Abstract: 586,761. Lubricating valves. NEWMAN, HENDER, & CO., Ltd. July 31, 1944, No. 14582. Convention date, July 2, 1943. [Class 135] Lubricant is . supplied at all times to diametrically opposite long grooves 40 on the face of a rotary plug valve which are not exposed to the line fluid, and only when the valve is fully open or fully closed, to shorter independent grooves 38 which have to move across the fluid passageway. The lubricant is supplied from an axial bore 44 in the plug through radial holes 42 to the grooves 40, which latter open into an annular groove 64 formed at the head of the plug. Communicating with the lower end of grooves 40 are radial and chordal passages 58, 56 and 54 which assist in the distribution of the lubricant over the lower seating surfaces. The grooves 38 are connected to the lubricant supply only in the fully open and fully closed positions of the valve by means of recesses 12 in the seating surface of the valve body which connect the grooves 38 with radial holes 52 from the axial bore 44. An annulargroove may connect the outer ends of the radial holes 42 and 52 at the top of the plug. The base of the plug is exposed to the line pressure through holes 36 to increase the seating pressure of the shoulder 62 of the plug against the body.

Abstract: 906,186. Controlling clutches. AUTOMOTIVE PRODUCTS CO. Ltd. Feb. 27, 1961 [April 26, 1960], No. 14599/60. Class 80 (2). [Also in Group XXIX] A valve for controlling a vacuum servomotor for a vehicle clutch has a connection 22, Fig. 3, with a source of vacuum, a connection 35 with the servomotor, and an atmospheric connection 33 in a piston 28 which carries an operating pad 38 and is urged outwardly into engagement with an annular stop 31 by a spring 29. Valve members 36, 37, slidable on a rod 39, are loaded by springs 45, 46 respectively and control ports 27, 32. The arrangement is such that when the piston 28 is in contact with the stop 31 the spring 46 is fully extended with the valve member 37 off its seat so that atmospheric pressure is effective in the connection 35, and the spring 45, which abuts a spider 41 on the rod 39, is compressed to such extent that the difference between the atmospheric and suction pressures acting on the valve member 36 is insufficient to open the latter. As the piston 28 is displaced to the left the valve member 37 becomes seated and the loadings on the springs 45, 46 are respectively decreased and increased to determine the pressure that is transmitted to the servomotor. In a modification, deflection of an operating rod 64, Fig. 4, bearing on a piston 55 which is rigidly connected with a slider 52, simultaneously reduces the compression of a spring 66 loading a valve member 65 which controls communication between the suction and servomotor connections 63, 58, and increases the compression of a spring 68 loading the atmospheric valve member 67. The slider 52, which is loaded by a spring 53 and has a through passageway 57, is clamped to a flexible diaphragm 51 which is subject to the pressure transmitted to the servomotor to provide " feel " for the operator.

Lengths 1 and 2 may be of the same material, e.g. nylon, P.V.C., polyethylene, but length 2 is preferably thicker and less flexible thereby to maintain length 1 in the required position. Length 2 is folded to the required angle when heated and then cooled to retain the fold permanently, and is bonded to length 1 by adhesives or heating. Pressure-sensitive adhesive 9 may be coated on the outer surface of body portion 6 for securing the strip to e.g. one of a pair of sliding glass panes, the outer edge of flap 4 contacting the other pane.
