IPC: B30B15/16
Filed: 1957-12-10
Abstract: 880,874. Hydraulic processes. LOEWY ENGINEERING CO. Ltd. March 10, 1959 [Dec. 10, 1957], No. 38414/57. Class 69 (2). [Also in Group XXII] A plant for the supply of working liquid at different pressures to hydraulic presses 10, such as forging or extrusion presses, comprises a pump 17, an hydraulic accumulator replenished by the pump which is operable at the pressure of the liquid in the accumulator at pressures substantially in excess of that pressure, a shutoff valve 31 for disconnecting the accumulator from the pump and press while leaving the pump connected to the press, and a control valve 15 for regulating the flow of liquid to the press. As applied to a forging press, pumps 17, 18, 19 are connected by by-pass valves 24, 25, 26 and the control valve 15 to the cylinder 10 of the press and by the valve 31 to the accumulator 20 which is supplied with air pressure from a bottle 21. When the valve 31 is closed, the pumps supply the liquid pressure to the cylinder or cylinders of the press and the crosshead 12 moves at a constant speed determined by the number of by-pass valves operative to connect the output of the pumps to the cylinder. Opening of the valve 31 connects the accumulator to the cylinder and the piston 11 moves rapidly as determined by the pressure in the accumulator. Control means in a tube 23 responsive to the pressure in the accumulator then selectively operate the by-pass valves to replenish the accumulator. A safety valve 30 may be operated by the control means if the pressure in the accumulator falls to a predetermined low level. The valve 31 may be operated manually, by gauges 32, 33 responsive to the pressure in the cylinder 10, or by a device 34 responsive to the speed of movement of the crosshead 12. The crosshead may be retracted by rams 13 in cylinders 14 supplied with liquid pressure from the accumulator which may also supply cylinders controlling the balancing of the crosshead. In another embodiment, one or more of the pumps are arranged to be permanently connected to the accumulator for replenishment thereof. In a further embodiment as applied to an extrusion press, six pumps are provided controlled by by-pass valves which can be selectively actuated to provide the ram with a number of different speeds which can be kept constant throughout the working stroke. An accumulator connected to the press is provided with a valve to control the rate of delivery of liquid to the press. The valves in all the embodiments may be of the solenoid-operated servo-type controlled manually or in response to the pressure in the cylinder of the press, the speed of the ram, or the liquid level in the accumulator.

Abstract: 977,139. Tyre valve connectors. WALTERS & DOBSON Ltd. Oct. 14, 1963 [Oct. 15, 1962], No. 38896/62. Addition to 872,246. Heading F2G. The tyre valve connector of the parent Specification is modified in that the hollow body 2 receives a cap 6 at its lower end, which cap is threaded for engagement with the body and to allow the cap axial movement. A compressible gland 10 is situated between the lower end of the slidable unit 12 and the inner transverse surface of the cap. The end cap preferably has an outer milled surface and contains a valve-receiving aperture 8. The cap 6 can be screwed further on or off the body 2 to adjust the initial size of the bore of the gland to compensate for wear or for various sizes of valve stems. The gland can be replaced by a further gland with a smaller bore for attachment to valves whose size cannot be compensated for by the above adjustment. Means for locking the end cap in an adjusted position can be provided. The spring-loaded pressure gauge valve member 38 slides in a nipple 28 screwed to the body of the valve and an unseating pin 36 attached to the member 38 serves to open the tyre valve as the tyre gauge is attached.

P.V.C. and pigment are added to a solution of cold setting epoxy resin which is ballmilled during evaporation of the solvent to form a coloured powder. After the epoxy resin has cured the powder is incorporated in an unpigmented P.V.C. plastisol containing a flowcontrol agent. A design of stitching &c. is applied to a shoe upper by a first mould in a R.F. heated press and at the same time projections are formed for locating the upper in a second mould in which the printed design is embossed.

Abstract: 1,092,778. Protective arrangements for capacitors. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 16, 1965 [Sept. 30, 1964], No. 39612/65. Heading H2H. A series capacitor installation having a protective arc gap 26 and extinguishing means 56, 58 has an arc current responsive circuit to delay operation of the extinguishing means until the arc current has decreased to a determined value. Overvoltage across a capacitor bank 14, 16 causes a gap 26 to break down, the current being limited by a reactor 32. An enclosed pilot gap 42 and capacitors 46, 50 stabilize the breakdown voltage of gap 26. Arc current energizes through a current transformer 64 relays 70, 78 closing contacts 68 to shunt a solenoid 60 to prevent operation of the air blast system. When the arc current drops relay 78 releases, shunting relay 70 through contacts 80, 82, and contacts 68 are opened permitting relay 60 to operate the air blast. When the arc current falls to zero a relay 60 is released shutting off the air blast. A current transformer 38 closes a by-pass switch 24 when the arc current becomes excessive. Protection is provided against over voltages on the current transformers by spark gaps 72, 76 and varistors 73, 77.

In a continuous cycle absorption refrigerating systems the weak solution leaving the generator is expanded at a pressure lower than that at which the generator operates to produce vapour rich in refrigerant which is absorbed by the solution leaving the absorber. As shown, the system utilises ammonia as refrigerant and water as absorbent, the weak solution leaving the generator 5 being passed to an expansion vessel 4 from which solution weak in refrigerant passes via a heat exchanger 7 and a cooler 10 to a main absorber 2. The vapour from the expansion vessel passes to an auxiliary absorber 3 where it is absorbed by solution supplied from the main absorber 2 by a pump 11. Strong solution leaving the auxiliary absorber is passed by a pump 12 through heat exchanger 7 and a pre-heater 8 to the generator 4 which is heated by a coil 50. Ammonia vapour from the generator passes over a cooled rectifying coil 51 to a condenser 6 from which liquid ammonia passes, via a heat exchanger 9 and a throttling valve 100, to an evaporator in a cold space 1.
