Title: Manufacture of laminated glass articles
IPC: C03C27/12
Filed: 1973-06-04
Abstract: 1470959 Laminated safety glass TRIPLEX SAFETY GLASS CO Ltd 28 May 1974 [4 June 1973] 26480/73 Heading B5N Flat or curved laminated glass windscreens are made by maintaining glass sheets, assembled with a transparent thermoplastic interlayer therebetween, at an elevated temperature whilst applying pressure to the major faces of the sheets for full bonding and cooling the bonded assembly, the pressure at the periphery of the interlayer being maintaned at a controlled amount lower than the aforesaid pressure for at least part of the period at elevated temperature. The reduced pressure may be applied via a flexible peripheral hollow rubber ring communicating with a pressure source or a vacuum pump. The interlayer may be polyvinyl butyral, in which case the bonding and peripheral pressures are both above atmospheric; bonding may be carried out in an autoclave at 2À0-14À0 kg./cm.<SP>2</SP>. Alternatively, the interlayer may be an ethylene copolymer as described Specification 1,166,443, when bonding is carried out in an oven at atmospheric pressure and the peripheral pressure is sub-atmospheric. When an autoclave is used, several assemblies may be stacked vertically therein (a suitable support being illustrated) and connected to a pressure manifold for applying the reduced pressure to the peripheral hollow rings. Preferably the assemblies are subjected to a pre-bonding process in which the peripheral zone is subjected to a vacuum via the hollow rings, e.g. at room temperature and at 90-120 C.; full bonding is then carried out at 120-160 C. with the desired peripheral pressure in the rings. When an autoclave is used, pre-bonding may take place inside or outside the autoclave. When bonding takes place at atmospheric pressure, the peripheral vacuum is maintained after prebonding. The pressure differential may be controlled at 0À14-1À05 kg./cm.<SP>2</SP> (a suitable control circuit for use with an autoclave being illustrated) and may be constant or gradually increasing; it may be applied during part or all of the full bonding stage and also during pre-heating, cooling or increase or reduction of the bonding pressure. The bonded laminate may be reheated and quenched to minimize haze, and interlayer edge portions which are extruded during bonding may subsequently be trimmed.

Abstract: 774,134. Automatic control systems; rectifying. RECORD ELECTRICAL CO., Ltd. Sept. 15, 1955 [Sept. 17, 1954], No. 26972/54. Classes 38 (2) and 38 (4). To reduce variations in output voltage of a selenium disc rectifier 2 over which a load, such as the ratiometer coils 3, 5 of a resistance testing instrument 3-6, is supplied from a handdriven alternator 1, the number of discs employed in the rectifier is such that the inverse voltage per disc exceeds the value at which, due to the non-linear inverse characteristic of the disc, the resistance begins to fall rapidly with increase of voltage. Preferably, the mean inverse voltage per disc exceeds twenty-five. The rectifier elements may be connected in a bridge, or voltage doubler, circuit. To reduce the effects of the internal reactance of the alternator, this may be tuned out by a shunt condenser 7 or, in the case of a voltage doubler arrangement, the condensers forming part of the rectifier circuit may be of such value as to resonate with the inductance of the machine. Specification 757,033, [Group XXXVI], is referred to in the Provisional Specification.

Abstract: 440,509. Injectors for dosing water. EVANS, D. J., Glen Cairn, Old Hadlow Road, Tonbridge, Kent. Sept. 20, 1934, No. 27059. [Class 71] [See also Group II] Comprises injector apparatus for adding hypochlorite, alum or aluminium sulphate solution, &c. to water and means for regulating the supply through a measuring-chamber which is provided with an air valve for temporarily breaking the flow of hypochlorite &c. Two similar sets of parts are shown in apparatus used for swimming baths. The hypochlorite is used for a portion of the water supplied to the bath. The injector is made of glass and is connected through rubber and ebonite connections to the liquid inlet and discharge. Water from the supply c passes to a nozzle i, and hypochlorite, controlled by a regulating- cone, needle, &c. valve x<1>, passes through a measuring-chamber n, a delivery pipe m, nipple k3, k<2>, past a non-return valve k to a branch h leading to an annular chamber around the nozzle i. The mixture passes through a conical mixing chamber e<1>. The chamber n is provided with an air-valve n and marks v, w. The valve u is opened periodically to allow the liquid to sink to the mark w. By noting the time required for the fluid to return to the mark v when the valve w is closed, the proportion of hypochlorite to water can be determined and correction made by adjusting the valve x<1>. In a modification, a glass non-return valve may be arranged in an enlargement of a solution-delivery nozzle which enters the injector chamber.
