Title: Method and apparatus for feeding supply packages to the winding stations of a thread winding machine
IPC: B65H67/06
Filed: 1964-12-16
Abstract: 1,091,249. Winding bobbins &c. W. REINERS. Dec. 16, 1964 [Dec. 21, 1963], No. 51157/ 64. Headings DID, DIF and D1J. Cop packages are supplied to the winding stations of a winding machine from a reserve magazine which is conducted past a device which lays ready the ,thread commencementfor example on the tube tip or in the tube bore-there being means for ascertaining whether any particular cop package had been conducted past the device before to avoid the device preparing the thread commencement again. As described the magazine is an endless belt which is moved step by step passed the winding stations arranged in a row, the belt, the cop donning arrangement and the winding stations being of known type, as for example in Specification No. 979,048. Cop packages are automatically or manually inserted into empty pockets 5 in belt 4, the newly filled pockets then stopping adjacent suction tube 64 which is caused to pivot about tube 65 by cam disc 69, thus actuating switch 66 of motor 61 driving friction roll 60, and applying suction to the bottom of the cop tube. The yarn end is sucked through tube 64 up to shears 67, there being a slot on the inner side of tube 64, and the shears, actuated by cam disc 70, cut the thread so that the thread end is sucked into the top end of the cop tube. The suction arrangement may be assisted by a blowing arrangement. The cam discs 69, 70 are rotated by worm 74 through clutch 76 which is moved into engaging position by a lever arrangement mounted on the pocket closing a switch in circuit a of motor 78, the pivoting of tube 64 moving the lever arrangement into an inoperative position so that if the prepared cop tube again stops opposite the tube 64, tube 64 will be inoperative. The lever arrangement is reset when the prepared tube is removed from the pocket or a fresh tube added. Alternatively instead of the lever arrangement, optical, electric, magnetic or mechanical registering means may be used-for example a magnetic sign may be formed on the tube foot-or there may be a device which ascertains the presence of the ready-laid thread commencement in the desired position. The winding stations may be in circular form, with a round magazine being used.

Filed: 1970-10-28
Abstract: 1313170 Bonded fibre fabrics MONSANTO CO 28 Oct 1970 [29 Oct 1969] 51192/70 Headings D1R and D2B [Also in Division C3] Nonwoven fabrics are bonded with a copolymer of ethylene/vinyl chloride/acrylamide and/or acrylic acid. The acrylic acid is generated by hydrolysing the acrylamide groups in the copolymer with a strong acid or alkali. Preferably at least one additional polar unsaturated monomer is included in the copolymer. A list of such monomers is given. The binder may also contain up to 50% urea-formaldehyde, urea-ethylene formaldehyde or melamine formaldehyde. The nonwoven fabric is made from one or more of the listed natural or synthetic fibres by air-laying with the application of suction, carding or garnetting to give an orientated web, which may be crosslaid, wet laying or spun bonding. The binder, which may be concentrated near the surfaces of the fabric, may be applied to the fibres in powder or as a dispersion before they are air laid, or the formed mat may be sprayed with or dipped into an aqueous dispersion of 5 to 90% copolymer, which may also contain sodium dioctylsuccinate as wetting agent and sodium oleate for foaming or octyl alcohol or a silicone antifoaming agent. The binder may contain as crosslinking agent sulphur, or compound which liberate sulphur on heating specified in U.S. 3356658, namely bis (dimethylthiocarbamoyl) disulphide and tetrasulphide, dipentamethylene tetrasulphide, 4, 4' dithiodimorpholine, alkyl phenolsulphides, sulphur chloride, hydrogen sulphide or sulphur thiocyamide. The product contains 2 to 200% by weight of binder. It may be passed through a size press, heated to coalesce the binder, and calendered.

Title: Improvements in the production of filaments, yarns and similar products from cellulose triacetate
IPC: D01F2/30
Filed: 1964-12-22
Abstract: 1,057,700. Cellulose triacetate filaments. SOCIETE RHODIACETA. Dec. 22, 1964 [Jan. 17, 1964], No. 52133/64. Heading B5B. Filamentary cellulose triacetate materials are produced by extruding a solution of cellulose triacetate in methylene chloride or a mixture of 80% or more by weight of methylene chloride and 20% or less by weight of an aliphatic alcohol having from 1 to 4 carbon atoms, for example methanol or ethanol, into an evaporative medium circulating in a closed circuit, removing the materials from the circuit when they have become coagulated, cooling the evaporative medium, at a point in the circuit beyond that at which the coagulated materials are removed, to a temperature at which the vapour pressure of the solvent is between 10 and 40% of atmospheric, reheating the medium, and returning the medium to the spinning cell in the neighbourhood of the point of extrusion. The spinning cell may be heated to between 60‹ and 150‹ C.; the evaporative medium, which may be air, is cooled preferably to between - 6‹ and 15‹ C., and reheated preferably to at least 50‹ C., for example to between 60‹ and 110‹ C. Apparatus suitable for the process is illustrated in the figure and comprises a tubular structure 1 in which spinning cell la is heated by jacket 2, cooling zone 1b is provided with jackets 3 and 4 for the passage of a cooling liquid to condense solvent vapour, and reheating zone 1c is provided with heating jacket 5. The spinning solution is extruded through spinneret 6 to form yarn 7 which is drawn from the cell by roller 9 after passing over guide pulley 8. Condensed solvent is drawn off through drain 10. The evaporative medium circulates by means of the drag exerted by the filaments and the difference in density between the vapour-laden medium in zones 1a and 1b and the vapour-free medium in zone 1c Examples describe the production of yarn, at various spinning speeds, from solutions of cellulose triacetate in a 90-10 methylene chloride-methanol solvent mixture, various values being chosen for the temperatures of the cell between the spinneret and where the yarn leaves the cell, of the cooled evaporative medium, and of the reheated medium.

Title: Method of eliminating the training effect in superconducting coils by post-wind preload
IPC: H01F6/06
Filed: 1975-12-22
Abstract: 1493299 Superconductor coil UNITED STATES ENERGY RESEARCH & DEVELOPMENT ADMINISTRATION 22 Dec 1975 [24 Feb 1975] 52452/75 Heading H1P A superconductive coil is wound (Fig. 1) of a composite conductor 8 in which plural filaments of, e.g. niobium titanium are embedded in a matrix 12 of, e.g. copper, aluminium, or copper nickel alloy and the conductor is covered with insulant 14 to prevent short-circuited turns; the conductor being prepared by casting superconductive rods into the matrix, swaging, rolling and drawing into wire with annealing at intervals to prevent work hardening. After winding a multilayer coil 18 (Fig. 2) is supported at 20 and a mandrel is closely fitted in the bore having a thermal coefficient of expansion less than the coil winding material, e.g. of non-nickel alloy. Surrounding bath 24 is filled with liquid nitrogen so that contraction exerts a radially outward force on the coil exceeding the electromagnetic force on the coil when it carries its designed current; thus leaving the conductors internally stressed whereby the design current in normal operation causes stress in the conductors within the proportional elastic limit of the material. The latter then undergoes no plastic deformation or slippage at its grain boundaries, and there is no frictional conversion of internal strain energy into heat so as to affect the superconductive state. On removal from the bath and removal of the mandrel, the coil requires no training to achieve a required state of internal stress. Such a postwinding preloading may also be achieved by pressure, in which the coil is supported and internal fluid pressure is applied to a hollow collet within the coil (Fig. 3, not shown) or by placing the coil in a close fitting annular cylinder which is contracted by internal fluid pressure (Fig. 4, not shown). Superincumbent winding layers are preloaded by forces coupled by physical contact of the underlying layers (Figs. 5, 6, not shown).
