Title: Heat treating polyurethane-sized glass fibres
IPC: D06M15/564
Filed: 1974-11-19
Abstract: 1484283 Treating glass fibres BAYER AG 19 Nov 1974 [20 Nov 1973] 50025/74 Heading D1P A process for the manufacture of a glass fibre reinforced plastics material comprises finishing glass fibres with polyurethane sizes or with sizing systems containing polyurethanes, subsequently heating the fibres and implanting the fibres into synthetic plastics material. The polyurethane may be applied as an aqueous dispersion or as a solution, for example in water, toluene or acetone. In addition to the polyurethane, lubricants such as alkoxylated fatty acid amides and adhesion promoters such as aminosilanes and emuisifiers may be present. The polyurethane size may be applied to the fibre in an amount to 0.3 to 3% and the heat-treatment may be carried out discontinuously or continuously. In the discontinuous process a plurality of sized elementary filaments grouped together in tows may be wound to produce rovings. The bobbins of rovings with or without a sleeve are passed into a heat-treating oven at the desired temperature, for example 550‹C for 10-30 mins. In the continuous process the heat treatment may be carried out by drawing the filaments over a metal plate which is at an elevated temperature or over a heating loop which may be heated electrically. The reinforced plastics material may be manufactured by impregnating bundles of glass fibres with liquid reactive resin compositions which may contain solvents. Suitable resins are unsaturated polyester resins, epoxy resins, phenol-formaldehyde resins, urea-formaldehyde resins, melamine-formaldehyde resins, furane-formaldehyde resins, cyanate resins, polyamides, polyurethane resins, hydrocarbon resins and silicone resins. Also the glass fibres may be introduced into thermoplastics materials in kneaders or screw mixers. Suitable thermoplastics are polyolefins, styrene polymers and copolymers, halogen-containing olefin homopolymers and copolymers, polyvinyl acetate, polyacrylic and polymethacrylic compounds, heteropolymers such as polyoxymethvlene and polyphenylene oxides, cellulose derivatives, polycarbonates polyesters and polyimides.

Filed: 1966-05-13
Abstract: 1,151,885. Packaging cans &c. IMPERIAL CHEMICAL INDUSTRIES OF AUSTRALIA & NEW ZEALAND Ltd. 13 May, 1966 [20 May, 1965], No. 51084/68. Heading B8C. [Also in Division F2] A process for packaging tins comprises the steps of concentrically assembling cylindrical tins 22 of the same diameter, optionally separated by cylindrical packaging cushions 23 of the same diameter to form a rod-like assembly, holding the assembly together in that form by means of a sheet wrapping 24 applied around the assembly, rotating the wrapped assembly round the longitudinal axis thereof, moving a ribbon 10 of flexible material past foam dispensing means and depositing a layer of nascent foam upon the ribbon, feeding the ribbon tangentially on to the rotating wrapped assembly at an angle to the longitudinal axis of the assembly so that the coated ribbon forms a spirally-wound envelope around the wrapped assembly with the coating in the annulus between the wrapping 24 and the ribbon, and, finally, allowing the foam to expand and cure, optionally under the influence of heat. The plastics foam material may be polyurethane, polystyrene, polyvinyl chloride, urea formaldehyde, epoxy resins, and polyolefines. The resulting assembly and wrapping together with the spirally-wound envelope is subsequently divided into cylindrical sections each containing one tin by cutting through the foam layer and, where used, the packaging cushions. The wrapped rod-like assembly (12), Fig. 1 (not shown), is rotated and moved forward longitudinally by a friction belt (17) driven by pulleys (16) and is supported by rollers (14) and a polytetrafluoroethylene-lined sleeve (18), the ribbon (2) being withdrawn from a roll by rotary motion of the assembly. One edge of the ribbon may be folded over prior to the winding thereof so as to free the foam dispensed from the nozzle (8), the edge afterwards being unfolded so that the ribbon re-assumes the free width and the foam-free edge overlaps the outer side of the internally, foam covered, preceding convolution of the ribbon whereby the spirally wound envelope is free from exuded foam. The ribbon may be wound so that the edges thereof abut or overlap. The rollers (14) and/or (15) may be driven to replace the belt and pulleys (16), (17). Curing of the foam is effected by a heater (21).

Abstract: 1,197,887. Yarn dyeing apparatus. HENRY ASHWELL & CO. Ltd. 17 Nov., 1967 [17 Nov., 1966], No. 51515/66. Heading D1L. Apparatus for the random dyeing (defined) of textile yarns comprises a conveyor for the yarn, means for locating the yarn to be dyed transversely across the conveyor from yarn locating means on one side of the conveyor to yarn locating means on the other side, means for applying dyestuff to the yarn in its passage on the conveyor to produce random dyeing thereof and means for setting said dyestuff on said yarn and finally means for removing the yarn from said conveyor. Yarn 3, either singly or as a plurality of strands, is fed from a supply means 5 through a reciprocating means to be located alternately around upstanding pins 2 of each of a pair of parallel chain conveyors 1, and thus transversely of the conveyor. The yarn is passed beneath a plurality of spray heads 13, which supplies dye of a single colour or of several colours, mounted for motion either transversely of the direction of motion of the belt or normal to the plane of the belt, or both so that the area covered by one particular dye is randomly varied. Subsequently the dyed yarn passes through a steam heated setting chamber, a washing bath and finally a drying chamber (Fig. 2 not shown). In one example yarn of 3000 denier was passed at a linear speed of 1" per sec. beneath spray heads spraying Fryalan Orange RL, Brown GRL, Yellow GL and Grey BL. The yarn was then set at 195‹C and humidity of 80%. In a further example relaxed Acrylic yarn of 2/28 count was sprayed with Astrozone Violet F3RL, Mascilon Red BL and Panacryl Blue E5G. The yarn was set at 105‹C and 80% humidity.

Filed: 1974-11-29
Abstract: 1464648 Determining position in a disc storage file assembly INTERNATIONAL BUSINESS MACHINES CORP 29 Nov 1974 [26 Dec 1973] 51737/74 Heading G1A Such a file assembly includes radiation source 5 and lens 7 projecting a beam perpendicular to the axis of disc pack 1 to two detectors 13a, 13b receiving radiation incident on strip-shaped areas elongated perpendicular to the axis and circumferentially displaced, supplying logic means generating signals representative of the axial position of the detectors. In shrouds 9, the light guiding passages 9a, 9b of photo-detectors 13a, 13b have their centres relatively displaced axially by half the thickness of a disc and contain twisted optical fibre arrays conforming to the detector areas at one end and at the other end to the slit apertures which are arcuate and parallel to the disc circumferences. Shrouds 9 and sources 5 can be moved as a unit relative to the stack. Voltage comparator circuits 17-1 to 17-4 develop signals as in Fig. 8, designated 17-1 to 17-4, dependent on the displacement of the slits relative to the nearest space between successive discs, and, from inverters 19-1 to 19-4 inverted signals 17-1 to 17-4. The outputs of 17-1 to 17-4 control, through AND circuits (A) Fig. 6 (not shown), conditioning latches (23-1 to 23-6) from which the outputs are applied to centring logic providing drive right drive left control signals for servoing the aperture system 9-11. The outputs of latches (23-2) and (23-5) are applied respectively to decrement and increment inputs of reversible counter (25) Fig. 7 (not shown) whose outputs are compared with the contents of address register (29) by vector comparator circuit (27) whose output is used for servoing the aperture system. The latching is so arranged that the movement of the disc edges due to fluttering cannot give a false count. Insert control logic (55), on receiving signals indicating that the aperture system is centred at the selected gap, produces an insert signal disabling the aperture system servo and controlling apparatus for separating the discs.

Abstract: 1,125,398. Impulse transmitters. STANDARD TELEPHONES & CABLES Ltd. 10 Dec., 1965, No. 52470/65. Heading H4K. An impulse transmitter has a drum rotatable on a horizontal axis 23 to place successive rows of ten latching plungers 20 beneath a fixed and corresponding row of ten solenoids 10, energization of one of the solenoids (by means of a ten button keyset or from a punched card reader) punching the corresponding plunger into the drum where it remains latched against the action of a restoring spring to temporarily store the value of the digit, registration of one digit causing the drum to be advanced to present the next row of plungers to the row of solenoids for registration of the next digit; a sensing arm 31 carried on a platform 30 within the drum and rotating with it about the same axis, but stepping back row by row under the influence of a restoring spring, scans along each row in turn and governs the generation of impulses in accordance with the digits stored, the plungers being unlatched to clear a row as each digit is read. The scanning arm 31, which at rest breaks home contacts 39, pivots about spindle 32 to step from one plunger in a row to the next against the restoring action of a spring 36 by a magnet 35 operating a ratchet drive. The magnet is pulsed by motor driven impulsing contacts the motor being switched on whenever the drum steps and carries the sensing platform away from its normal position beneath the row of solenoids 10. Each pulse stepping the sensing arm 31 is repeated to line until the arm engages the projecting end of a latched plunger whereupon contacts 33, 34 on the arm make to operate a relay (not shown) which bridges the line to mask the transmission of further impulses. The relay also operates a release magnet connected over the home contacts 39 whereby the arm snaps back to its home position and by breaking contacts 39 disconnects the release magnet. The relay also diverts impulses from the magnet 35 to a stepping switch which counts out an interdigital pause before the sensing arm is allowed to start scanning the next row. Energisation and deenergisation of the release magnet also operates a lever 27 of an escape mechanism to step the platform 30 back to the next row of plungers. If this row has a digit stored it will be scanned, but if it has no digit and lies beneath the solenoids 10 the platform 30 is in its home position and disconnects the impulsing motor. The plungers may be unlatched and cleared by the pressure of the contacts 33, 34, or may be cleared as the platform 30 steps back to a new row by a sweeping bar. If a plunger fails to latch, the sensing arm may step to a fixed stop in the tenth position or step to an eleventh position to operate an alarm.
