Title: Composite building element
IPC: B29C70/50
Filed: 1968-09-17
Abstract: 1,244,735. Moulding reinforced foam structures. COMPAGNIE DE SAINT-GOBAIN. 17 Sept., 1968 [27 Oct., 1967], No. 44145/68. Heading B5A. In moulding a post or a beam, strip metal is bent into a tube and fed continuously through a mould formed from vented metal or glass fibre reinforced polyester elements 28 which are urged together by rams 30 as they move round conveyers 29 at the same speed as the tube is fed therethrough. Polyurethane foam is delivered from gun 32 to coat the tube and to fill the mould. Spray guns 34 spray polyester or epoxide resin over the foam and reinforcing glass fibre 36 is wound on to the resin by drums 35 and 41. A second gun 38 may spray resin on to the reinforcements. A device 39 removes air bubbles. The whole is smoothed by a funnel 42 of elastic material urged against the moulding by an inflatable chamber 44, which may precede either a second funnel defining a hot air circulating curing chamber, or an infra-red heating system 46. The funnel 42 may be replaced by an inflatable enclosure intermittently reciprocable with the moulding. The post or beam is cut into sections by saw 50. The reinforcement may be small fibres which are sprayed on or longitudinal bands of woven glass fibres applied on to the foam (Figs. 12 and 13, not shown).

Abstract: 1,181,617. Continuous production of polyamide foams. FARBENFABRIKEN BAYER A.G. 20 Sept., 1968 [20 Oct., 1967], No. 44796/68. Headings C3C and C3R. Polyamide foam is continuously produced by melting a mixture of a lactam, e.g. caprolactam, with a catalyst, e.g. an alkali metal or alkaline earth metal formate, and an activator and an expanding or a compound which functions as both, e.g. an isocyanate, polymerizing the melt with vigorous stirring to form a prepolymer having a relative viscosity of 1À15-2À5 (as a solution of 1 g. of prepolymer in 100 ml. mcresol at 20‹ C.), transferring the prepolymer to a mould and polymerizing to completion with shaping and foaming. In the example caprolactam, sodium formate and a silica gel are heated, the melt is cooled and hexamethylene diisocyanate and an alkylene oxide-silicone block copolymer (as pore regulator) are added, the mixture is melted, fed to a reactor, stirred and the prepolymer produced is then fed to a mould where it is polymerized to completion with foaming. An apparatus is illustrated (not shown).

Title: Switching circuit

IPC: H02M7/162
Filed: 1962-12-03
Abstract: 947,476. Automatic control of voltage. STANDARD TELEPHONES & CABLES Ltd. Dec. 3, 1962, No. 45486/62. Heading G3R. A full wave bridge rectifier arrangement, comprising rectifiers MR1, MR2 and siliconcontrolled rectifiers SCR1, SCR2 is fed from a transformer T1 and supplies to load terminals 1, 2 through a filter network 4, 22, C1, C2, and a commutating rectifier MR3. A voltage sensing bridge, incorporating a Zener diode Z1, is connected across the load terminals and a current transformer CT is connected between the transformer T1 and the bridge rectifier, a load current dependent signal being derived from a potentiometer RV2. The control electrodes of the silicon controlled rectifiers SCR1, SCR2 are fed through transistors X4, X5 from two square wave unidirectional voltages of 180 degrees pulse width which appear in antiphase across Zener diodes Z4 Z5 due to the regular action of the resistor R10 and the Zener diodes. The transistors X4, X5 are biased 'on' and 'off' by a sinusoidal phase-shifted voltage applied to a primary of a transformer T3, the secondary voltages being substantially square waves due to the non-linear B/H characteristic of the transformer. The phase shifted sinusoidal voltage is derived from a secondary of the transformer T2 through an RC network comprising a capacitor C7 and a variable resistance formed by the bridge rectifier and a transistor X3. The base bias of the transistor X3 is controlled through a transistor X1 by the out-of-balance signal from the load voltage sensing bridge so as to tend to maintain the load voltage constant. When the load current exceeds a limiting value the voltage across the potentiometer RV2 exceeds the breakdown voltage of the Zener diode Z3 a transistor X2 is rendered conductive and over-rides transistor X1 to render transistor X3 non-conductive. The transistors X1, X2 are supplied from a supply stabilized by a resistor R4 and Zener diode Z2. In a modification the system is adapted to a three-phase supply.

The polyol used in forming the prepolymer may be a monomeric or polymeric polyol or a mixture thereof. In making moisture-curing prepolymers it is preferred to use a major proportion of a polyol having a M.W. of at least 500.

Suitably the prepolymer is prepared in the presence of an inert solvent. The coating compositions are said to be suitable as wood finishes, marine finishes and enamel finishes, e.g. for automobile bodies. In a typical Example 1-isocyanato-3-isocyanatomethyl-3,5, 5-trimethyl cyclohexane is reacted with a propylene oxide/1,2,6-hexanetriol polyether in the presence of dibutyl tin dilaurate and a xylene/ ethoxy ethanol acetate solvent mixture to provide an isocyanate-terminated prepolymer which is coated on a metal plate and allowed to cure by exposure to atmospheric moisture.
