Title: Method of manufacturing polymer particles having uniform crosslin king and expanded shaped articles formed therefrom
IPC: C08J9/18
Filed: 1972-03-21
Abstract: 1383924 Cross linked polyolefins and foamable particles thereof KANEGAFUCHI KAGAKU KOGYO KK 21 March 1972 [25 March 1971(3)] 13277/72 Headings C3C and C3P Cross linked polyolefin resin particles are prepared by a method which comprises forming a suspension in water of polyolefin resin particles, by adding an aqueous solution of a surface active agent, containing a soluble or finely dispersed cross linking agent and a suspension stabilizer compatible with the cross linking agent, preferably a water-insoluble inorganic metal compound, and heating to a temperature sufficient to cause penetration of the cross linking agent into the particles and subsequently to a temperature sufficient to initiate a cross linking reaction. Where the particles produced have a gel content of 10 to 70% foamable cross linked particles may be prepared by adding a foaming agent thereto, and the foamable material may be prefoamed, stored and subsequently foamed by heating in an open mould. The resin may be polyethylene, polypropylene, an ethylene/vinyl acetate copolymer, or a polymer or copolymer of butadiene, styrene or vinyl chloride. The surface active agent may be a polyoxyethylene octylphenol ether, sodium dodecylbenzene sulphonate or sodium dialkyl sulphosuccinate. The cross linking agent may be dicumyl peroxide, 2,5-dimethyl-2,5-di-t.-butylperoxyhexane, di-t.-butyl perphthalate or t.- butyl hydroperoxide, optionally with a cross linking assistant such as divinyl benzene or acetylene. The inorganic metal salt may be a phosphate, oxide or hydroxide, e.g. calcium phosphate, zinc phosphate and aluminium hydroxide. The foaming agent may be a volatile hydrocarbon or halogenated hydrocarbon, and foaming may be effected by exposure to steam, hot air or liquid, infra-red radiation or high frequency magnetic field. In examples polyethylene resin particles are cross linked with dicumyl peroxide in aqueous suspension in the presence of surface active agents and (1, 4 and 6 to 9) calcium phosphate, (2 and 5) zinc phosphate and (3) aluminium hydroxide, and the products foamed with (1 to 4, 6, 7 and 9) difluorodichloromethane and (5 and 8) dichlorotetrafluoroethane.

Filed: 1959-04-21
Abstract: 915,197. Valves. ADAMS, K. April 21, 1959 [April 21, 1958], No. 13572/59. Class 135. An automatic non-return butterfly valve is actuated through a driving device by a differential area piston of which the larger area is exposed to the pressure downstream of the butterfly whilst the smaller area is exposed to the upstream pressure. The valve is arranged also for manual actuation into any position and the driving device incorporates a clutch to change over from one form of actuation to the other. The butterfly 5 has its shaft 10 eccentrically mounted with respect to the valve seat 4 so that it tends to open under the upstream pressure. Shaft 10 carries a loose pinion 34 which may be coupled to the shaft through a sliding clutch 47, the pinion 34 being engaged by a rack 44 connected to the differential area piston 23 of which the larger area 23b is exposed through pipe 31 to the downstream pressure whilst the smaller area 23a is exposed through pipe 30 to the upstream pressure, whereby in this coupled position the valve automatically opens under an upstream pressure sufficiently exceeding the downstream pressure and closes under reverse or zero flow conditions. Shaft 10 also carries a loose worm-wheel 41 which may alternatively be coupled to the shaft by clutch 47, the worm-wheel being engaged by a worm 44 operated by a hand wheel 46. The piston carries a throttling member 54 cooperating with the pipe 30 or an adjustable throttle may be fitted in this pipe. Pinion 34 may be made fast with the shaft 10.

Title: Emergency and parking brake actuator for road vehicles
IPC: B60T17/10
Filed: 1973-03-21
Abstract: 1414719 Spring applied brake actuators SO DE RE P 21 March 1973 [24 March 1972 26 Jan 1973] 13660/73 Heading F2F An emergency and parking brake actuator has in a casing 1 a movable wall operating a brake push-rod 9 and subjected to at least one spring for brake actuation and on the other hand to fluid pressure to neutralize the spring(s) wherein the wall and the push-rod are connected by a coupling which is disconnectable by relative angular displacement of two coupling members comprising a key 16 and a keyway member, one coupling member being operated by a rotatable shaft 28 for disconnection and the keyway member having a sloping guide face for accepting the key for reconnection after such disconnection. A piston 2 actuated by springs 3, 4 has a sleeve 17 fixed thereto, the sleeve having two sloping key guide faces 22, 23, a key entry/exit passage 21, a further guide face 24 for final reconnection of the key 16 and abutments 19, 20 for the key. For disconnection after brake application, the push-rod 9 having actuated a control rod of a known pressure actuator adjacent to the casing 1, the key 16 abuts the abutment 20; rotation of a hexagonal extension of a part 25, rotatably fixed on the push-rod 9 and having the key, by the shaft 28 allows the key to be displaced through the passage 21, and the push-rod 9 to be retracted. Subsequent piston retraction by fluid pressure allows the faces 22, 23, 24 to guide the key 16 back into position. The hexagonal extension may protrude from the casing to be the shaft, or the sleeve 25 may be angularly rotated for coupling disconnection. Alternatively, the springs 3, 4 and the piston 2 may surround the known pressure actuator. For remote operation of the disconnection, the shaft 28 has a radial lever acted upon by push-rod controlled by a spring- released, pressure-actuated rolling diaphragm and piston assembly, the pressure fluid being obtained by a pump, or extra supply, or from a vehicle wheel.

Title: A new or improved servo motor installation for centrally locking and unlocking a plurality of closure means on a motor vehicle
IPC: E05B65/36
Filed: 1963-04-05
Abstract: 983,820. Latches. DAIMLER-BENZ A.G. April 5, 1963 [April 7, 1962], No. 13698/63. Heading E2A. An arrangement for the locking and unlocking of a plurality of closure devices on a motor vehicle comprises vacuum servomotors under the control of a central change-over valve which is mechanically connected with and operated by the locking means of the door situated adjacent to the drivers seat. As shown in Fig. 1 the installation comprises a pipe 11 connected at one end to an induction pipe of the engine, and at the other through a valve 12 to a vacuum reservoir 13 leading through pipe 14 to a change-over valve 16. Vacuum servomotors 19 to 21 operate locks 24 to 26 on the doors, motor 22 operates lock 27 of the boot and motor 23 operates a petrol tank locking device 28. The motor comprises parts 19<SP>1</SP>, 19<SP>11</SP> to 23<SP>1</SP>, 23<SP>11</SP> separated by diaphragms bearing rods 30 to 34 extending through parts 19<SP>1</SP> to 23<SP>1</SP>. Pipes 17 connect the valve 16 to parts 19<SP>1</SP> to 21<SP>1</SP>, and a pipe 18 connects all the parts 19<SP>11</SP> to 23<SP>11</SP> to the valve 16. In operation, actuation of lock 38 by key means causes, through movement of lever 37 and linkage 36, displacement of valve 16 resulting in blockage of communication between pipes 14, 17 and connecting pipes 14 to 18 leading to chambers 19<SP>11</SP> to 23<SP>11</SP>. Through valve 16 air at atmospheric pressure flows into pipe 17, and as there is a vacuum in pipe 18, thus all the diaphragms move to positions shown by dotted lines, thus moving the rods and their associated latching means to the locked position. Unlocking of the locking means 24 from outside is effected by unlocking lock 38 by key means, thus rotating lever 37 to move valve rod 16<SP>1</SP> through linkage 36. Valve 16 is thus actuated to establish connection between the vacuum reservoir and chambers 19<SP>1</SP> to 21<SP>1</SP>. Since the lock 27 of the boot is connected to atmospheric air by means of a vent and not to pipe 17 the lock is always closed on actuation of the central closure means, but this may be prevented by closing a valve 35 to cut off the part 23<SP>11</SP> from the reservoir 13. The boot lock is unlocked by key means. In the petrol tank lock the diaphragm is returned by spring means. The lock 38 may be operated externally by key means, from inside by a push rod 39, and also moves a handle connected to the rod 40. The lock 24 may be manually or mechanically operated independently of the central locking system.
