IPC: C03C27/12
Filed: 1967-03-23
Abstract: 1,227,943. Laminates; forms of wood. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 March, 1968 [23 March, 1967; 5 May, 1967], Nos. 13679/67 and 21029/67. Headings B5L and B5N. [Also in Divisions Cl and E1] A method of making a laminate comprises locating a heat-sensitive polymeric adhesive composition between two spaced panels, the said adhesive composition contacting selected surface areas of the two panels, and heating the adhesive to form a bond between the adhesive and the panels, the adhesive comprising a copolymer of ethylene with one or more hydroxy or epoxy lower aliphatic monoesters of acrylic or methacrylic acid and with from 0 to 55% by weight of the copolymer of an ester of acrylic or methacrylic acid, a vinyl ester or styrene, said copolymer containing by weight at least 35% of ethylene and: (a) from 1 to 8À5% of free hydroxy groups or (b) from 0À1 to 3% of epoxy oxygen or (c) both free hydroxy groups up to 8À5% and epoxy oxygen up to 3% provided that the weight of free hydroxy groups plus (ten times the weight of epoxy oxygen) is always at least 1% by weight of the copolymer. The panels may be of wood, e.g. plywood, metal, e.g. aluminium, plasterboard, concrete, glass, asbestos cement or synthetic resin. The adhesive is preferably applied to the periphery of the panels, the space between the panels being filled with air or other gas or liquid. The adhesive may be applied as a paste or solution or in the form of a section or gasket which may be of solid form; alternatively, the section or gasket may comprise a core or substrate, e.g. of plasticized polyvinyl chloride, polyurethane foam, an extruded aluminium profile, timber, glass or metal bearing a coating of the adhesive. Where glass panels are used, an adhesive promoting agent may be applied to the surfaces of the panels and/or the adhesive. The heating may be effected by resistance or induction heating of carbon or metal powders or granules or a metal foil or wire incorporated in the adhesive.

Abstract: 1,229,925. Brakes. GIRLING Ltd. 3 June, 1969 [14 June, 1968 (2); 1 April, 1969], Nos. 28296/68, 28299/68 and 16888/69. Heading F2F. A tandem master cylinder comprises a first piston 23 connected to an operating rod 14 which carries a slidable shroud 33, moved by a stiff spring 35 to operate venting and pressure valves 58, 63 to produce a pressure in cylinder space 53, and a floating secondary piston 50 having a recuperation valve 79, 80 such that pressure in space 53, not only feeds a primary braking circuit at 54, but also moves the secondary piston 50 to close valve 78, 80 and so produce a pressure in space 71 fed at 73 to a secondary braking circuit. A main piston 12 is connected through lost motion in recess 18 to the operating rod 14. The valve 58 is normally held in the tilted, open position, shown, by the front of the shroud 33, but on movement of operating rod 21 it moves down the cylinder to allow closure of this valve and opening of pressure-supplying valve 67. Both valves are biased to the closed position by springs 61 and 68 respectively. This source is connected through a non-return valve. The piston 50 has a reduced waist 75 connected to reservoir connector 74, and this is connected to space 71 via valve 79, 80 in the piston. If the high pressure source fails, the lost motion of main piston 12 is taken up and a light compression spring 40 allows a spacer 34 to abut plate 38. Strong spring 35 is thereafter compressed as the main piston 12 moves to provide pressure in space 53. If this fails, the end of rod 14 will abut the piston 50 to energize the secondary brake circuit. In the modification shown in Fig. 2, the main piston 111, 112 is integral with the operating rod 114 and it works in a reduced bore 113. At the end of rod 114 there is a combined shroud and first piston 117 held in the retracted position by spring 123 abutting against a stop 125 located by sealed rings 129, 131. The secondary piston 126 lies within these rings and is sealed with respect to them and is held retracted by spring 140 passing through the secondary pressure space 139. The primary pressure space 150 leads out at 151. Forward movement of the shroud, operates the tilting valves, as before, and this pressure also moves the secondary piston 126 forwards, and so seals a port 137 to cut off the pressure space 139. On failure of the pressure source, the secondary piston is pushed directly by the end of rod 114. Specification 1,229,926 is referred to.

Abstract: 1330305 Bridge circuits TAYLOR SERVOMEX Ltd 21 June 1971 [19 March 1970] 13340/70 Addition to 1242675 Heading G1U A circuit of the type shown in Fig.2, referred to as a "bridge-type circuit", in which a temperature sensitive resistor R- is connected with a standard resistor R S  and a transformer T 1  having turns N S  and N T  as shown, and which when no output is produced by an out-of-balance amplifier A satisfies the standard bridge balance equation, namely R T  /R S =N T  /N S , (assuming that the impedance looking in to the winding N  S  is infinite, which condition is achieved in developments of the circuit by appropriate buffer amplifiers) is characterised by the provision of a compensating circuit which, unlike the parent specification, simulates the effect of a negative resistance in parallel with the temperature sensitive resistor without there being any component effectively connected in parallel with the temperature sensitive resistor, and thereby renders the overall circuit more linear to temperature variations. A variety of circuits of simulating a negative resistance are shown, all of which, for example that of Fig. 4, include a buffer unity-gain amplifier A' to ensure that the effective impedance looking in to winding N S  is infinite.
