Title: Yarn Assembly Apparatus and method for False Twisting Yarn
IPC: D02G1/02
Filed: 1968-05-07
Abstract: 1,187,531. Processing yarn. TURBO MACHINE CO. 7 May, 1968 [8 May, 1967], No. 21448/68. Heading D1F. In yarn treatment comprising separating a two-ply multi-filament yarn into its constituent plies, resistance to the upstream movement of the twist is imposed at a plurality of upstream points, whereby the degree of twist is progressively decreased from full twist at the most downstream of said points to substantially zero at the most upstream of said points. As described, said treatment relates to yarn crimping as described in Specification 1187532, in which two multi-filament yarns 12, 13, Fig. 5, pass in substantially flat, untwisted formation through a first groove 31 formed in a heated body 30, the twist, pre-imparted to the yarns, develops progressively in stages as the yarns engage successive points on a series of rollers, pins or guides, the twisted yarn 18 passes through a second groove 32 in body 30, the heated yarn is cooled to set the twist, and the constituent crimped yarns are then separated and are wound on respective take-up rollers. In Fig. 5, the untwisted yarns engage a point 294 on a fixed, larged-diameter pin 94, whereafter the twist begins to develop. The yarns then pass around a small-diameter pin 95 adjustably fixed in a slot 96, and finally engage pin 94 at a point 194 diametrically opposite point 294, whereafter the fully-twisted yarn passes to groove 32. In Fig. 3 the untwisted yarns pass downwards through a crotch between an upper freely-journalled roller 81 and a lower freely-journalled roller 82 disposed at right angles to roller 81, and ascend through the opposed crotch between the rollers. Twisting commences at the first point of contact 187 on roller 81, and is completed after the final and diametrically opposite point of contact 184 on roller 81. In Fig. 7, the yarns pass in succession through a guide 108, over a tension wheel 107, through a guide 106, and around a pair of pins 101, 102 carried in diametrical opposition by a pivotal disc 103 secured in adjusted angular position by a thumb nut 105, the yarns changing in direction after each point of engagement.

Title: Improvements in the application of coverings to wires applicable to the insulation of electric conductors and to other purposes
IPC: H01B13/12
Filed: 1931-07-29
Abstract: 388,738. Insulated conductors. BRITISH, INSULATED CABLES, Ltd., Prescot, and NISBETT, G. H., Huyton, Hey House, Huyton, both in Lancashire. July 29, 1931, Nos. 21688/31, 30046/31,. 31135/31, and 1040/32. [Class 36.] A tubular covering is formed on bare or insulated wires by placing the wire between two sheets of paper moistened with water, or between two thicknesses of a folded and moistened sheet, and then applying heavy pressure to the paper to seam the two thicknesses together. The covering is preferably formed by passing the wire, with moistened. paper strips disposed on either side thereof, through registering grooves formed in a pair of rolls adapted to compress and seam together those portions of the paper strips extending beyond the edges of the grooves. The paper covering, which may include animal or mineral fibres such as asbestos, may have a tight or loose fit on the wire and may be provided with longitudinally-extending ribs. Fig. 1 shows. apparatus for covering several wires simultaneously, the wires being drawn from reels 1 over guide rollers 2, 3 to a pair of pressure rolls 4 through which they pass together with moistened paper strips 5, the drums of the rolls 4 being formed with a plurality of registering grooves each adapted to receive one wire. The correct spacing of the wires during their passage through the rolls is maintained by a guide-plate 21 secured to the frame of the rolls. The composite strip 8 delivered by the rolls 4, which consists of paper-covered wires. connected together by thin paper webs, is passed round drums 9, 10 and then through a tubular drying chamber 11 wherein the moisture contained in the strip is removed. The chamber, 11 has internal rollers 13 for supporting the strip and is heated by hot gas which enters and leaves the chamber by ducts 14, 15 respectively. The dried strip is passed round a drum 16 and then carried over a number of rollers 17 on which it is divided up into its component wires and led off to reels 18. Two wires are severed from the strip 8 on each roller 17, the wires being led round the roller to shear the thin paper web connecting them to the strip. Portions of the connecting web remaining on the wires after severing may be removed by passing the covered wire through buffing rolls. Ribbed coverings may be formed on the wires by shaping the grooves in the rolls 4, as shown in Figs. 6 and 7. In the modified arrangement of Fig. 8, two wires 34 enter a folding guide-funnel 35 in which a dry paper strip 36 is folded around them, the paper-enclosed wires then passing under a roller 38 carried in a bath of water 37 to a pair of grooved pressure rolls 39 similar to those already described. In a further modification, the moisture is removed from the strip 8, Fig. 1, by passing it through a bath of impregnating material maintained at a temperature higher than the boiling point of water.

Abstract: 813,613. Aerials. ANTIFERENCE Ltd., and BEST, N. M. July 27, 1956 [July 29, 1955], No. 21958/55. Class 40 (7). An aerial for use with two radial signals of different frequencies, both polarized in the same direction, comprises a first half-wave dipole for the lower frequency which is centre fed and a second shorter half-wave dipole for the higher frequency formed as a continuous conductive element parallel and adjacent to the first and having the same plane of symmetry. The ratio of the two frequencies is limited to the range 1.2: 1 to 4.8: 1 and the length of the second dipole may require modification from the normal resonant length to compensate for the proximity of the other dipole and to take into account the actual frequencies to be used. In a simple embodiment (Fig. 2) elements 21 and 22 form the first dipole and are supported by junction box 24 in which they are connected to a feeder. The junction box is supported by an arm 25 which also carries the single conductive rod 23 forming the second dipole. The rod 23 may be electrically connected to the arm 25. In a modification of this embodiment (Fig. 3, not shown) the second dipole is supported from the first by insulating struts and is not in contact with the support arm. Reflector elements for both frequencies may be added and if the direction of propagation is the same for both frequencies these may be mounted on a common cross-arm. Director elements may also be provided. One way of incorporating director elements into the array is that described in Specification 813,614. To increase the bandwidth at the higher frequency two similar second dipoles may be used mounted close to each other and equi-distant from the first dipole. Reference has been directed by the Comptroller to Specification 759,968.

Abstract: 785,952. Fluid-pressure servomotor-control systems. FOXBORO CO. Aug. 2, 1955 [Aug. 12, 1954], No. 22222/55. Class 135. In a pneumatic pressure transmitter the output pressure of which is the pressure of gas in a chamber to which gas is supplied and from which it is simultaneously exhausted, the chamber is supplied through a first pressure regulator and exhausted through a second pressure regulator, both regulators being responsive to the output pressure. The supply pressure regulator maintains a constant pressure drop across a fixed restriction leading to the chamber and the exhaust pressure regulator maintains a constant pressure drop across a relief valve which bleeds gas from the chamber. With this arrangement, the output pressure is exactly equal to the pressure to be measured and is independent of the high pressure supply or the ambient exhaust pressure. Fig. 1 shows the invention applied to determine the hydrostatic pressure in a tank 11 having an opening 13 to which the pressure transmitter unit 10 is applied. The unit comprises a flanged body 15 having an annular boss 16 by which a sealing ring 17 and a flexible diaphragm 19 are clamped over the opening 13. An output chamber 20 is formed between the body 15 and the diaphragm 19, and has an inlet port 21 connected to a pressure-regulating unit 12, an exhaust port 22 controlled by a relief valve 24, and an output port 23 connected to a dead-end pneumatic system for pneumatically operating indicating, recording or controlling apparatus. The pressure regulating unit 12 comprises a supply chamber 26, an exhaust chamber 28, a central chamber 27 separated from the other two by flexible diaphragms 29, 30 respectively. The diaphragm 29 supports a member 33 containing a fixed restrictor passage 35 and connected to an inlet valve 32 supplied through a pipe 31. A spring 34 tends to open the valve 32. The central chamber 27 is connected to the output chamber through a pipe 36. The diaphragm 30 is loaded by a spring 41 and carries an exhaust valve 40 controlling an outlet port 38 to the atmosphere. The diaphragm 19 may be a composite structure composed of a resilient member and a corrosion resistant material such as tantalum. A teflon gasket may be used. In a system for measuring the liquid level in a tank, two pressure transmitters as described above are located at different levels on the tank wall and their output pressures are applied to a differential pressure measuring unit.
