Abstract: 1,268,630. Stitch bonded fabrics. COSMOPOLITAN TEXTILE CO. Ltd. 10 Oct., 1969 [19 Oct., 1968], No. 49695/68. Heading D1R. A stitch bonded fabric is produced by progressively advancing a fleece 10 through a sewing knitting machine comprising a set of needles 11 with hooks 14 which are reciprocated to penetrate the fleece 10. A rod 13 is slidable in a groove 12 in each needle and penetrates the fleece with the needle but is halted before it reaches the opposite face of the fleece. The needles 11 are halted before their greatest thickness has penetrated through. the fleece. Threads 29 from guides 26 are passed over the hooks 14 and the needles are retracted to have their hooks closed by the wires 13. The threads are thus drawn through the fleece in the form of loops and bundles of fibres are collected from the face of the fleece in the hooks. After retraction of the needles from the fleece and moving the fleece downwards the needles are again inserted so as to cause the loops of threads and fibres to interengage on the shanks of the needles and the cycle is repeated to produce the stitchbonded fabric.

Heading H1D [Also in -Division G2] A method of preparing mosaic phosphor screens for cathode-ray `tubes includes the steps of applying a photo-sensitive screen layer to a foundation plate, exposing the layer both to a pattern of actinic energy and to a flood of actinic energy, the flood exposure being less than that required by itself to significantly insolubilize the layer, and developing the layer. The photo sensitive screen layer comprises polyvinyl alcohol, ammonium dichromate and phosphor which is applied to a tube faceplate having a multi-apertured shadow mask electrode disposed substantially parallel to and spaced from the faceplate, the layer is then flood exposed to ultra-violet light directed from a broad area source through the faceplate 'and then pattern exposed to ultra-violet light through the shadow mask from a point source located substantially at the centre of deflection of the election beam of the finished cathode-ray tube. The pattern exposure may be made before the flood exposure. The flood exposure is made by twentyfive tree-watt lamps arranged in a two dimensional array positioned five inches above the faceplate, and the pattern exposure by a 1 Kw. high pressure mercury arc lamp.

Abstract: 1493399 Measuring angular displacement electrically GENERAL ELECTRIC CO 28 Nov 1974 [3 Dec 1973] 51567/74 Heading GIN [Also in Divisions G4 and H2] An electrical signal to control the speed of a D.C. motor 12 driving an electric vehicle (see Division H2) is produced by rotation of a manually-operable lever 38 which alters the relative position of a Hall element 22 and the magnetic field produced by a permanent magnet 32, 34, the members 22, 32, 34 constituting a conventional Hall generator, Fig. 5 (not shown), whose magnet (40) is rotatable by the lever 38 about a central position.

Title: Strips for use in or as transmission belts

Abstract: 1477650 -Laminated belting PNEUMATIQUES CAOUTCHOUC MANUFACTURE ET PLASTIQUES KLEBER-COLOMBES 29 Nov 1974 51907/74 Heading B5N [Also in Division F2] In a driving belt, a tensile member is formed of at least two superimposed and interconnected layers 1, 2, which are each composed of a flexible elastomer or plastomer -material as a matrix, reinforced with discontinuous elongated fibrils dispersed through the matrix, with their predominant orientation in the longitudinal direction of the tensile member providing an elasticity such that a tensile stress of 15 kg/cm<SP>2</SP> in the tensile member gives rise to an elongation not exceeding 1%. The matrix material preferably receives not less than 5% by weight of elongated fibrils, which are composed of a crystalline polyolefin having a molecular weight exceeding 500,000. Dispersion of the fibrils is achieved by subjecting the matrix to a mixing operation, which may be carried out at a temperature close to or higher than the melting point of the polyolefin, so that the polyolefin particles become broken up and drawn out into elongated fibrils during the course of the mixing operation, when the matrix material becomes subjected to shear forces. At the same time, or subsequently, the matrix material is also subjected to a drawing-out operation, between the rolls of a rolling mill or a calender, thereby causing the fibrils to become oriented generally in a direction parallel to the direction of drawing. The resulting flat sheet material provides two or more layer strips 1, 2, Fig. 1, each cut at an angle relatively to the predominant fibril direction, so that the assembled pair of superimposed strips 1, 2, have symmetrically differing predominant directions, 3, 4, forming angles less than 10 degrees with the belt centreline. The strips 1, 2, may be secured together directly, Fig. 1, by vulcanization or hot welding, or alternatively they may be similarly secured, Fig. 2, on either side of an interposed layer 5, composed of similar matrix material without fibrils. The flat belts of Figs. 1, 2, may be used on cylindrical or cambered pulleys, or in other embodiments either of these belt constructions may serve as a tensile member in a composite belt having a facing of trapezoidal, multiple-V, Fig. 4, transversely toothed or corrugated form. Typical compositions of elastomer and plastomer matrix materials are described.
