Abstract: 375,306. Bowls for yarn-winding and sectional or other warping and beaming machines. HOLT, H., Atlas Iron Works, Whitworth Road, Rochdale. March 18, 1931, No. 8287. [Classes 120 (ii) and 142 (iv).] Carrier bowls or guide-pulleys are so mounted in relation to a brake that when the winding or drawing forward of the yarn is arrested, as by the action of the stop-motion, the bowl is moved against the brake to prevent overrunning. A bowl e is mounted in ears a<3> which are carried on an adjustably weighted lever a<1>, Fig. 2, or on a spring-supported frame comprising rods u, Fig. 5, so that, during normal running, it is maintained by the tension of the yarn away from a brake arm g<1>, Fig. 1, or arms y, Fig. 5, but, when winding is arrested, is moved into contact therewith by a weight or spring b, Fig. 2, or springs v, Fig. 5. Wooden collars c mounted in the ears a<3> serve as bearings for the pivots of the bowl and to retain lubricant therefor, and shrouds l are provided to overlap the ends of the bowl. In the Provisional Specification it is stated that the supporting lever or frame is provided with guide wires to lead the yarn to the bowl.

Abstract: 1,018,678. Bearings. GLACIER METAL CO. Ltd. Feb. 28, 1964, No. 8495/64. Heading F2A. In a journal bearing, Fig. 2 (not shown), the journal or the bush 2, has at least one lubricating pocket 7 having an edge 8 which is inclined with respect to the axial generator line of the bearing surface, the inclination remaining constant or increasing towards the edges of the bush. When the journal and the bush move relatively to one another, lubricant flows over the edge 8 into the clearance gap of the bearing, and foreign particles contained in the oil are deflected into the corners of the pocket where they flow outwardly to the edges of the bush. Alternatively the foreign particles may pass from the corners of the pocket, through channels communicating therewith.

Title: Improvements in production of textile filaments, fires and yarns
IPC: D02J1/22
Filed: 1944-05-09
Abstract: The strength and softness of filaments, fibres or yarns made from thermoplastic resins are improved by applying to the surface of the freshly-spun filaments a coating of a finely-divided water-insoluble solid compound incompatible with the resin, twisting the filaments and thereafter stretching in moist heat at 90 DEG  to 200 DEG  C. Suitable filaments are made from polyvinyl acetal resins, polyvinyl chloride resins, after - chlorinated polyvinyl chloride resins, polystyrene resins, and polyamide resins, and particularly conjoint polymerization products of a vinyl halide and acrylonitrile containing from 45 to 80 per cent of the halide.  The finely-divided solid material may be deposited on the filaments prior to the stretching, either by treatment with a suspension of the solid material in an aqueous or other vehicle, or by precipitating the solid material in situ on the filaments; preferably, the solid material is applied to filaments which have been freshly spun and still contain residual solvent.  In an example, a dispersion in acetone of a vinyl chloride-acrylonitrile resin heat-stabilized with dibutyl tin dilaurate is spun into aqueous acetone and the filaments formed are stretched, passed through an aqueous suspension of colloidal clay, dried, washed, twisted and finally stretched 800 per cent at 125 DEG  C. in steam. In a second example, dry spun vinyl chloride-vinyl acetate filaments are similarly coated with bentonite, twisted and stretched 463 per cent at 123 DEG  C. in steam.  A third example is given in which unstretched vinyl chloride-acrylonitrile yarn is treated with a solution of tetraethyl orthosilicate in isopropyl alcohol, treated with warm water to hydrolyse the ethyl silicate to silica gel, and stretched 800 per cent at 128 DEG  C. as in the first example.  In a fourth example, vinyl chloride-acrylonitrile filaments are passed through a solution of sodium carbonate and soap and then through a solution of calcium chloride.  The filaments are then stretched 800 per cent at 128 DEG C. in steam.  In a fifth example, vinyl chloride-acrylonitrile filaments are passed consecutively through aqueous solutions of aluminium chloride and ammonia and then stretched 800 per cent at 128 DEG  C. in steam. Other suitable insoluble solids are sulphates of barium, calcium and lead; carbonates of barium, calcium, magnesium, lead and zinc; oxides and hydrated oxides of aluminium, titanium, zinc, tin and silicon; water-insoluble phosphates, silicates and borates; and alkyl and aryl silicates and borates which readily hydrolyze in presence of water.

Title: A method of reducing a synthetic thermoplastic to a powder
IPC: B29B9/00
Filed: 1962-03-07
Abstract: Chlorinated polyethers derived from pentaerythritol and having units of the general formula: <FORM:0943718/C3/1> and which may contain polyvinyl chloride are reduced to a powder by dissolving or dispersing in the molten state in a hot solvent which boils at a temperature at or above the melting point of the plastic such that, after cooling, the solution forms a jelly, and wherein the greater part of the solvent is then removed from the jelly by subjecting the latter to pressure, and the residual solvent is removed under pressure in conventional manner e.g. by compressed air, centrifuge, rollers or a multiplate press, below the melting point of the thermoplastic. Specified solvents are Tetralin and orthodichlorobenzene. After removal of solvent from the jelly by rollers, the thin skin thus obtained is rubbed to produce crumbs before removal of residual solvent. Examples refer to treatment of "Penton" alone and in admixture with P.V.C. to produce a fine uniform powder suitable for aqueous suspensions or plastisols.

The resin may be moulded as such or absorbed on a fibrous material and formed into sheets.  The material may be moulded under low pressures, no counter being necessary and the mould need not be wholly metallic, a metal wall supported by concrete being suitable.  Fig. 1 shows a suitable mould comprising a steel sheet 1, a concrete base 2, a resinous sheet 5, a loose filler material 6, and a cover 7.  Figs. 3, 4 and 5 show methods of jointing or repairing moulded pieces 8, 13 and 18 by means of sheet material 9, 15 and 19.

Title: Improvements in or relating to control systems
IPC: G05B7/02
Filed: 1959-03-13
Abstract: 848,314. Automatic control systems. BAILEY METERS & CONTROLS Ltd. March 13, 1959 [March 15, 1958], No. 8891/59. Class 38 (4). In an electrical control system for a variable one electric signal generator is replaced by another by supplying an artificial input to the incoming signal generator so that its output, which is normally blocked, is varied until it is equal to that of the outgoing signal generator, whereupon change-over occurs and the outgoing signal generator is disconnected. As shown in Fig. 1, a signal derived from a circuit 1, which may be manually controlled or responsive to the deviation of a variable, is normally applied to a terminal 3 to which apparatus (not shown), e.g. a servomotor controlling the variable, is connected. When it is desired to transfer control of the apparatus from circuit 1 to a signal, which may also be responsive to deviation of the variable, applied through an amplifier 21 from a terminal 24, a switch 52 is operated manually to energize a relay 30 and disconnect a negative bias source 40 from amplifier 21. The negative bias of amplifier 21 falls gradually by virtue of a condenser 22 until the output potential of amplifier 21 applied to the base of a transistor 50 equals that of circuit 1 applied to the emitter of the transistor whereupon the transistor conducts to energize a relay 10 and effect the transfer by changing over the connection of terminal 3 from circuit 1 to the output of amplifier 21. Relay 10 is self-holding and remains energized unless switch 52 is opened to reinstate control by circuit 1. Duplication of the equipment so that reinstatement takes place under the same conditions as the transfer is referred to. Condenser 22 forms part of a feedback circuit which introduces an integral component into the output of amplifier 21.
