Patent GB-1081406-A (GB)
Title: Improvements relating to the production of non-woven fabrics
IPC: D04H3/16
Filed: 1964-10-26
Abstract: A non-woven fibre structure is made by extruding a molten polyurethane prepolymer, capable of cross-linking, through apertures arranged in one or more rows to form one or more sheets of continuous filaments, causing the prepolymer to cross-link, stretching the filaments by gas streams forced out of slots one on each side of each row of apertures and adjacent and parallel to that row, and leading the or each sheet of filaments together with its associated gas streams, through an open-ended duct through which the filaments and gas pass substantially without turbulence, the filaments being stretched whilst being kept parallel to but separate from one another, and forming a fleece by collecting the sheet or sheets of filaments on a carrier.  The filaments may be stretched by gas or vapour flowing in the same direction as the filaments but at a higher velocity and preferably cross-linking is at least started while the filaments are being stretched by using moist air as the gas or vapour.  Cross-linking may also be effected by passing the filaments through a bath of water.  The molten polyurethane prepolymer may be extruded through one or more rows of apertures and another molten, fibre-forming polymeric material may be extruded through one or more other rows of apertures, and the filaments of that polymeric material stretched and set while keeping them separate from one another, the fleece being formed from the sheet or sheets of filaments of that polymeric material and from the sheet or sheets of polyurethane filaments.  Fleece formation may be effected by causing the filaments to become entangled with one another on a slowly rotating drum having a screen surface through which suction is applied.  Preferred prepolymers are macro-diisocyanates of polyethers or polyesters and which contain glycols or diamines to bring about cross-linking.  In general, the methods and apparatus of the parent application are utilised.  In Examples:- (1) a fleece is made from a polyurethane prepolymer consisting of 100 parts of a condensation product of adipic acid ethylene glycol polyester and diphenylmethane 4, 41-diisocyanate, partially cross-linked with 30 parts butane-1,4-diol; (2) a mixed fleece is made from filaments of a polyurethane polymer as in (1), intermingled during spinning with polycaprolactam filaments.

Abstract: 1279246 Road traffic signals on vehicles FLEXIBLE LAMPS Ltd 16 Dec 1969 [16 Sept 1968] 43871/68 Heading G4Q A road vehicle electric indicating lamp circuit includes a thermal relay connected in the indicating lamp circuit and arranged to receive transmitted heat generated by a flow of current in a road lamp circuit separate from the indicating lamp circuit, the thermal relay being operated automatically by the transmitted heat when the road lamp circuit is switched on, and being connected in the indicating lamp circuit in such a way as to reduce the current flow through the indicating lamps, and hence to reduce their brightness, when so operated by the switching on of the road lamp circuit. In the illustrated embodiment, the brightness control circuit for the stop lamp circuit comprises a bimetallic thermal relay 10A mounted in a side or tail lamp housing 11A close to the lamp bulb 12A so that thermal radiation from the lamp filament will fall directly on the relay 10A and actuate it within a short period of the switching on of the lamp. The relay 10A which is normally closed is connected in parallel with a resistance 14A in the live line 16 of the associated stop lamp circuit. When the side and tail lamps are switched on, the relay 10A is opened and the resistance 14A brought into the stop lamp circuit so that the current flow through the stop lamp bulbs 18 is reduced. The flashing direction indicator lamp circuit comprises a pair of rear indicator lamps 20, a selector switch 21 and a flasher unit 23. A brightness control circuit comprises a resistance 14B across which a thermal relay 10B is connected in parallel. In this case, the relay 10B is mounted close to a resistance heating element 25 connected in parallel across a side or tail lamp bulb 12B. When the side and tail lamps are switched on, the heat generated by the element 25 will immediately open the relay 10B and bring the resistance 14B into series with a selected rear indicator lamp 20. The relay 10B and element 25 do not need to be mounted in the casing of a side or tail lamp, and they may be mounted adjacent one another in any convenient position. This invention enables the brightness of the stop and/or indicator lamps of a trailer to be controlled by means provided in the towing vehicle without the need for providing further electrical connections between the trailer and towing vehicle.
