Patent GB-754240-A (GB)
Title: Bonding process
IPC: C03C25/323
Filed: 1954-03-09
Abstract: A process for bonding plastic to glass comprises pretreating glass with a copolymerizable unsaturated polyester containing free carboxyl groups and producing the plastic in situ by copolymerizing an unsaturated polyester with a monomeric unsaturated compound, such as styrene, in the presence of a catalyst, e.g. benzoyl peroxide, and in contact with the pretreated glass.  The polyesters used in pretreating the glass take part in the polymerization and may be obtained by condensing excess unsaturated dicarboxylic acid, e.g. maleic, with a polyhydric alcohol, or by reacting an unsaturated dicarboxylic anhydride with a saturated polyester, or by reacting a saturated dicarboxylic acid with an unsaturated polyester, e.g. one derived from maleic acid.  The other polyester may be derived from maleic and phthalic acids and butylene glycol.  Examples 1 and 3 describe the bonding of glass plate and plastic, and Example 2 describes the production of a laminate of layers of glass fabric made from pretreated filaments.ALSO:Glass, e.g. plates, is pretreated with a copolymerizable unsaturated polyester containing free carboxyl groups and the glass is then bonded to plastic by copolymerizing an unsaturated polyester and another monomer (see Group IV(a)) in contact with the pretreated glass, e.g. by heating in the presence of benzoylperoxide.

Title: Fluid Control Valves.
Inventor: HANCOCK KENNETH GEORGE
IPC: F16K15/18
Filed: 1967-02-13
Abstract: 1,188,022. Valves. ELECTRO-HYDRAULICS Ltd. 13 Feb., 1968 [13 Feb., 1967], No. 6874/67. Heading F2V. The flow of fluid from a volume of pressure fluid, such as that within a mine roof support, is controlled by first and second valves 11, 13 operated by a piston 2 so that initially the valve 11 is opened to permit a restricted flow until the pressure falls to a predetermined value when the valve 13 is opened automatically to permit a substantially unrestricted flow, all of the flow passing across the seat of the valve 11. Fluid pressure admitted through the connection 4 raises the piston 2 and the valve 11 so that fluid can flow through the valve 13 from connection. 17 to connection 19 by way of an orifice 15. The pressure drop through the orifice holds the valve 13 closed until it has fallen to a value which can be overcome by the upward force on the piston 2. To reset the roof support, the connection 4 is vented and fluid under pressure admitted through the connection 19. In a further embodiment, the second valve consists of an inverted cup shaped member sliding within a fixed ported sleeve. The valves may also be arranged side by side with their flow paths in series and be operated by separate pistons or a common piston via a lever mechanism. Solenoids may be used in place of pistons.

Title: Improvements in and relating to methods of forming contact layers for semiconductor devices.
IPC: C25D15/02
Filed: 1967-02-14
Abstract: 1,177,414. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 14 Feb., 1967 [16 Feb., 1966], No. 6931/67. Heading H1K. [Also in Division C7] A contact layer for a semi-conductor device is made by depositing on a substrate a coherent metal layer with semi-conductor inclusions capable of alloying with the metal from a fluid containing semi-conductor particles in suspension at a temperature below that at which said alloying occurs. The substrate may be of tungsten, molybdenum, nickel, nickel-iron or nickel-iron-cobalt alloy, ceramics such as alumina, or a semi-conductor body. Where self supporting layers are required use is made of a temporary substrate, e.g. of stainless steel or metallized glass, from which the layer can be peeled. The layer metal may be aluminium, gold, silver, cobalt or nickel or combinations thereof while the particles may consist of one or more of germanium, silicon, and gallium arsenide. Deposition of the metal may be effected by electroplating or electroless deposition from specified solutions. In a typical example boron doped silicon particles are incorporated in gold deposited on a gold plated boron-diffused area of an oxide coated N-type silicon body while antimony doped particles are incorporated in a similar fashion in a coating on the opposite face of the body. The assembly is completed by heating to above the eutectic temperature of gold and silicon. In another embodiment a nickel header to which a silicon diode, transistor or integrated circuit element is to be attached is electroplated in a gold potassium cyanide bath containing in suspension silicon particles of less than 5 Á diameter. Alternatively the header is electroless plated with nickel from a bath containing silicon particles.

Title: Improvements relating to the control of electric motors
Inventor: WALTON JAMES RIGNELL
IPC: H02P27/02
Filed: 1955-03-10
Abstract: 810,119. Control of A.C. motors. ELECTRIC APPARATUS CO. Ltd. March 10, 1955, No. 7134/55. Class 38 (3). Saturable reactors 13, 14, 15, connected in the primary circuit of a three-phase motor have a common D.C. control winding 16 the excitation of which varies in magnitude with, and in the same sense as, the secondary current of the motor. An increase of the load causes an increase of the output of a rectifier 21 in the circuit of the motor whereby the impedance of an auxiliary saturable reactor 25 is reduced and the primary voltage of transformer 27 increased. The control winding 16 is connected to the secondary winding of the transformer through a rectifier 31 so that an increase of motor load leads to a corresponding change in the motor primary voltage, so stabilizing the speed. The saturable reactors 13, 14, 15, have another common control winding 17 which opposes the winding 16 and is energized with rectified current from a transformer 33 having its primary winding either connected to supply terminals 7, 8, or in parallel with the A.C. winding of the reactor 13. In the latter case, the excitation of winding 17 decreases when that of the winding 16 increases. In another arrangement, the rectifier 21 is connected across a tapped rotor resistor 18, and a non- linear resistor 37 prevents appreciable excitation of the control winding of the reactor 25 until the rotor current exceeds a predetermined value. The reactor 25 may alternatively be connected on the secondary side of the transformer 27. A modified system comprises only two reactors in the primary circuit of the motor.

Title: Improvements in or relating to the Patterning of Carded Webs
Inventor: GRAHAM WILLIAM STUART
IPC: D01G15/70
Filed: 1967-02-17
Abstract: 1,172,303. Random colour pattern of carded webs. W. S. GRAHAM. 19 April, 1968 [17 Feb., 1967], No. 7652/67. Heading D1N. A random colour pattern of the yarn issuing from a carded web 14 containing fibres of various colours and passing over a guide roller 16 arranged at the delivery end of a carding machine 10 is produced by randomly reciprocating the roller 16 in the direction of its length. One reciprocation of the roller occurs each time a switching device 20 is actuated, the device 20 comprising a rotatable drum 22 with internal vanes 26 which carry a number of balls 28 to the top of the drum from where the balls drop down a vertical chute and sometimes actuate a switch arm 34. The switch arm actuates a drive means 40 which reciprocates the roller through an oscillatory linkage 48, 50, 60. An overriding device is provided which itself actuates the drive means when the switching device has not operated for a predetermined time. The overriding device consists of a shaft 64 normally driven by drive 74 as long as the roller is not reciprocated, a length of chain 76 carrying a weight 78 at one end being attached to the shaft such that the weight contacts a switch operating member 80 when if has been raised a certain extent by rotation of shaft 64. Reciprocation of the roller causes clockwise swinging of arm 66 carrying shaft 64 and disengagement of the drive 74 from the shaft so that the weight can then cause free unwinding of the chain 76.
