Title: Improvements in or relating to electro-magnetically actuated valves
IPC: F16D65/28
Filed: 1953-01-28
Abstract: 728,534. Electromagnetically-actuated valves. SOC. D'INVENTIONS AERONAUTIQUES ET MECANIQUES S.I.A.M. Jan. 28, 1953 [Feb. 13, 1952], No. 2455/53. Class 135. An electromagnetically-actuated valve controlling the supply of fluid to fluid-operated apparatus, e.g. the operating piston 21, Fig. 2, of a relay valve 20, comprises a body 1 of magnetic material surrounded by the electromagnet winding 10 and enclosing a chamber 5. Pressure fluid is supplied to the chamber from line 3a through a restriction 4 and escapes through an outlet 6 controlled by closure member 7 of magnetic material. Progressive variation of the current in the winding caused, e.g., by operation of a potentiometer, causes progressive movement of member 7 towards or away from the outlet thus providing a progressively increasing or decreasing pressure respectively in chamber 5. The pressure in the chamber is applied through line 13 to the piston 21 which is thus progressively moved against or by the spring 25. In another arrangement, two electromagnetically-actuated valves control the relay valve piston 21, Fig. 3, which has centring springs 25a, 25b, the closure members 7 being interconnected and pivoted at 26. The windings are arranged so that as the current in one is progressively increased the current in the other is progressively decreased. In a modification, the two outlets are opposed and a single closure member is movable therebetween towards one or the other.

Abstract: 1,243,051. Toughened polyvinyl aromatic compositions. BRITISH PETROLEUM CO. Ltd. 13 Jan., 1969 [18 Jan., 1968], No. 2702/68. Heading C3G. A toughened polyvinyl aromatic composition is produced by a process comprising (1) dissolving a rubber and, optionally, a preformed polyvinyl aromatic compound in a monomeric vinyl aromatic compound, adding water and an amount of suspending agent sufficient to reduce the viscosity of the mixture of rubber solution and water but insufficient to produce a stable suspension, and polymerizing the monomer using a free radical initiator to a conversion which is sufficient to achieve phase inversion on suspension but does not exceed 15%; and (2) adding a further quantity of suspending agent to provide a total quantity of suspending agent sufficient to produce a stable suspension and continuing polymerization under suspension conditions. A wetting agent may also be employed in the process and acrylonitrile may be present. In the example, a solution of polybutadiene and polystyrene in styrene is polymerized in a first stage in an aqueous medium containing hydroxyethyl cellulose, benzoyl peroxide and lauroyl peroxide, to which are added dicumyl peroxide, di-t-butyl peroxide, t-dodecyl mercaptan and white oil during said stage. At the end of the first stage, additional water and hydroxyethyl cellulose are added together with Na 2 HPO 4  and polymerization is completed.

Abstract: 414,391. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, and GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, both in London.-(Assignees of Spanner, H. J. ; 117, Chausseestrasse, Berlin.) Feb. 1, 1933, No. 3125. Convention date, Feb. 1, 1932. [Class 39 (i).] The metal-vapour filling of the high-pressure lamp described in Specification 410,787 contains a trace of sodium in addition to metals such as mercury, cadmium and zinc, the quantities of the sodium and of the other metals being adjusted so that the main lines of their spectra are of the same order of magnitude and that a substantially white light is obtained. The envelope may be of "Duran" glass with a high silica content, this glass assuming a greenbrown tint after use of the lamp and fluorescing, due to the presence of sodium on its surface. The thermionic electrodes may be of tungsten or oxide-coated and may be heated by the discharge or independently. In manufacturing the lamp, the metals to be introduced are placed in chambers 4, 5, leading off the exhaust tube 3. The lamp is exhausted, rare gas is introduced, mercury is added by heating the chamber 5 and the lamp is outgassed by a heavy-current mercury-vapour discharge. After re-exhausting, the final filling of argon at 6 mm. pressure is introduced and the metals are distilled from the chambers 4, 5 until a photometric spectroscopic test indicates that the quantities of metals arc correct, the lamp being then sealed off.

Title: Back gauge control for paper cutting machines
IPC: G05B19/16
Filed: 1962-01-26
Abstract: 986,768. Guillotine cutting - machines. MIEHLE-GOSS-DEXTER Inc. Jan. 26, 1962 [Jan. 26, 1961], No. 3128/62. Heading B4B. [Also in Division G5] The back gauge of a paper-cutting machine is controlled by sensing means 16 which pick up signals from a magnetic tape helically wound on a drum 11, the rotation of which is synchronized with the travel of the back gauge. The drum, mounted on a hub 1 1a on a shaft 9 and arranged to be driven through gearing 5, 7, 8 by the back gauge lead screw 2, is axially displaceable against the action of a spring 40 to set one of twelve channels recorded on the tape in alignment with one of two pickup heads 16 which are movable along the drum. To axially set the drum in relation to a selected channel, a cam 43 mounted on a cam-shaft 44 is arranged to displace the shaft 9 (against a spring 40) when turned through gearing by a motor 55 controlled by manually-settable switches 56. A timing device is arranged so that when the cam has turned the requisite amount it is held by a spring-urged detent pivoted at 52b engaging a notch in a disc 45 which is mounted on the cam-shaft 43. Release of the detent is effected by a solenoid 54 which is energized simultaneously with the motor. The armature of the motor is axially displaceable so as to act as a clutch for the cam-shaft drive. An illuminated indicator 44 is also mounted on the cam-shaft for viewing through a window 47. The twelve channels recorded on the tape may be arranged in two sets of six for coaction with the respective heads. The heads 16, as shown in Figs. 3 and 4, are carried by a bracket 18 of a carriage 15 which is arranged to be traversed along the drum by rotation of a screw-shaft 6 driven from the lead screw 2, the heads being carried by spring- urged arms 19 on a block 22 which is adjustable along a slide 23 on the bracket 18 by means of a manually-operated cam 26 so that one of the two heads can be set to a marked position on the tape and arranged to be guided at the exact helix angle of the tape; signals from the heads control the motor driving the lead screw 2. To wind the tape on the drum, a storage reel 104, Fig. 8, and spring-motor assembly 109, 110, 111 are attached to the bracket 18 and the end of the tape on the reel 104 is attached to the drum 11, Fig. 3, by a pin 13; the lead screw 2 is then rotated so that the drum winds the tape off the reel, which then acts via shaft 103 to cause the drum 109 to wind the spring 110 from the drum 111 at a uniform tension. When the drum has been fully wound, the tape, still under tension, is fastened to the drum by a clamp 14a and then severed. Specifications 890,164, 904,158 and 928,174 are referred to.
