Title: Improvements in the treatment of thermoplastic elastomeric yarns
Inventor: WILSON DAVID
IPC: D01F6/72
Filed: 1968-01-30
Abstract: 1,201,433. Treating elastomeric segmented polyurethane yarns. CLUTSOM-PENN INTERNATIONAL Ltd. 30 Dec., 1968 [30 Jan., 1968], No. 4774/68. Heading B5B. [Also in Divisions B8 and D1] Thermoplastic elastomeric yarns in which the yarn material contains at least 85% by weight of segmented polyurethane ("Spandex" yarns) are treated by simultaneously stretching the bare yarn to an extent of less than 200% of its length prior to stretching and subjecting it to a temperature at or above its sticking temperature in the range 215-300 C. over a period of time not exceeding 30 seconds. The process may be carried out on a covering machine as part of a covering operation on the bare Spandex yarn or as part of a winding operation, e.g. when winding bare Spandex yarn from one package to another. The yarn may be treated under such conditions of stretching and temperature as to result in increased elongation at break. Advantageously, the bare yarn may be stretched whilst it is being caused to run over and preferably in contact with an electrically heated plate. In the covering machine shown in the diagrammatic drawing, a bare Spandex yarn Y is drawn from a supply package 1 and finally wound up on to a take-up package 2. The covering machine comprises two covering spindles 3 and 4 which support bobbins 5 and 6 of covering threads. The Spandex yarn Y runs freely right through the spindles 3 and 4, and the latter are spaced apart axially in, and arranged to rotate about, a straight upward portion of the path of travel of the yarn. The yarn Y passes from the supply package 1 over the first and second feed wheels 8 and 9, the wheel 9 being driven at a higher peripheral speed than wheel 8 to stretch the yarn and the yarn being at the same time heated by being guided through a heater 7 incorporating an electrically heated plate 7<SP>1</SP> over and in contact with which the yarn travels. The covered stretched yarn after its passage through the covering spindle 4 passes round a take-up roller 10 and is laid evenly upon the package 2 by the traversing guide 11. The temperature of the plate 7<SP>1</SP> may be measured by means of a Thermophil temperature probe. The sticking temperature of the bare Spandex yarn is defined as the temperature at which the yarn will just stick to a heated brass block when held against the surface of the block for 5 seconds with a 200 gram weight. The temperature of the block is measured by means of a Thermophil temperature probe.

Title: Manufacture of polymerisation products
IPC: C08F2/04
Filed: 1936-09-28
Abstract: Gaseous monomeric compounds capable of polymerization with the aid of a per compound, e.g. a salt of a per-acid, or an organic peroxide, are polymerized, in the presence of such polymerization accelerator, by conducting the gas at, or slightly above atmospheric pressure, on to the surface of a liquid medium in which it is insoluble or only partially soluble and in which it is finely distributed by intensive stirring, further gas or vapour being introduced to replace that consumed during polymerization. Thus a vessel is partly filled with the liquid medium containing a polymerization acceleration, e.g. an alkali persulphate or perborate, or acetyl, benzoyl or oleyl peroxide, and, if necessary, an emulsifying agent; the space above the liquid is filled with the gas, with expulsion of air, and the gas is finely distributed in the liquid by intensive stirring, the gas consumed being replaced from a gas meter or container.  Examples of monomeric compounds are vinyl chloride, vinyl methyl ether, butadiene, vinyl ethyl ether, and, in the presence of benzine, vinyl formate.  Mixtures of gases may be similarly treated; further, the liquid may contain a solid or liquid monomeric compound, e.g. vinyl acetate, vinyl propionate, vinyl butyrate, acrylic acid methyl ester, acrylic acid ethyl ester, acrylic acid nitrile, maleic acid, maleic acid ethyl ester or maleic anhydride; mixed polymerizates are thus obtained.  Liquids specified are water, paraffin hydrocarbons and chlorinated hydrocarbons. Examples are given of the production of mixed polymerizates from (1) vinyl chloride and maleic acid dimethyl ester, (2) vinyl chloride and vinyl acetate, (3) vinyl methyl ether and maleic anhydride and (4) butadiene and acrylo-nitrile.

Abstract: Grey cotton fibres, yarns, plied yarns, cords, &c. and other natural cellulosic fibres, such as flax, ramie, jute and hemp, are successively treated with an alkali metal salt of a cyclo-alkane carboxylic acid, tensioned while wet to just short of breaking point, and dried while under tension.  Sodium, potassium or lithium salts of naphthenic acids whose individual or mixed acidic number is at least 160 are preferred, but alkali-metal salts of any cyclo alkane or alkyl-substituted cyclo alkane carboxylic acids falling within the general formula CnH2n-xO2, x being an integer from 2 to 8 and n being greater than 5, may be used.  Specified salts are those of (a) cyclopropylacetic, -propionic, -butyric, -valeric and -caproic acids; (b) cyclobutylacetic, -propionic, -butyric, -valeric and -caproic acids; (c) cyclopentylacetic, -propionic, -butyric, -valeric and -caproic acids; (d) cyclo-hexylacetic, -propionic, -butyric, -valeric and -caproic acids; (e) alkyl-nuclear-substitution products of (a), (b), (c) and (d) above; (f) alkyl-nuclear-substitution products of cyclopropyl-, cyclobutyl-, cyclopentyl- and cyclohexyl formic acids; and (g) the mixed cycloalkyl carboxylic acids occurring in petroleum naphthenic acids also falling within the general formula given above. The concentration of the aqueous solution of the naphthenates used is from 2 per cent to about 3.6 per cent by weight, but may be higher. Prior to tensioning, the material to be treated may be dipped into this solution or the solution may be sprayed on to the material or the material may be passed through a bath containing the solution, the treatment being carried out quickly.  The temperature of the aqueous solution may be room temperature, but it may be varied. Stretching is carried out either immediately after the above treatment or after the material has been dried and re-wetted.  The material may be washed with hot or cold water during stretching.  The treated yarns or cords may be rubberized.  Examples are given of the treatment of a variety of grey cotton yarn.  Specification 545,716 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use as above of salts of cyclopropyl formic acid. This subject-matter does not appear in the Specification as accepted.

Abstract: 693,099. Refrigerating. GILKES & GORDON, Ltd., G., and CREWDSON, E. March 5,1952. No. 5737/52. Class 29 [Also in Groups XXVI and XXVIII] Cold-air machines. Air compressed in a compressor 30 is supplied at 33 to a cylinder 1 in which reciprocates a double-ended free piston 8, 9 which is rotated continuously about its axis of reciprocation, the expanding air acting on the upper piston 8 and the work of expansion being absorbed by the lower piston 9 compressing air in the lower part of the cylinder. The expanded cooled air passes by a line 34 and heat exchanger 31 back to the compressor 30, a portion being removed for cooling purposes. The expansion piston 8 is shaped to conform with the cover 7 of the cylinder and has an annular series of ports 20 adapted in the uppermost position of the piston to register with inlet ports 14 in an annular chamber 13 communicating with the outlet of the compressor. The air in expanding forces the piston downwardly -until the ports 20 register with exhaust ports 18 in the cylinder and return motion of the piston forces the cold expanded gas through the exhaust ports. During each expansion stroke the gas in the lower part of the cylinder is compressed by the piston 9 and a proportion escapes through a spring-loaded valve 22 and passes through a throttling device 39 and cooler 36 to return to the lower part of the cylinder at 27 at approximately atmospheric temperature and at a pressure equal to that of the cold gas leaving the exhaust ports 18. The remainder of the compressed gas below the piston 9 returns the piston to its uppermost position to receive a fresh charge of gas to be expanded. A pipe 40 connects the port 37 to a port 41 in the cylinder wall to equalize the pressure in the cylinder space between the two pistons 8, 9 and avoid gas flow past baffle plates 25 which minimise heat leakage. The piston is caused to rotate continuously about its axis by a small jet of air or gas from an orifice 28 acting on a vane 26. Maintenance of the necessary relation between the angular and longitudinal positions of the piston for operation of the ports is effected by mechanical or electrical means, e.g. the vane 25 may comprise a bar magnet or electromagnet co-operating with a magnet 27 entering through the cylinder wall so that at this magnet or electromagnet co-operating with a magnet 27 entering through the cylinder wall so that at this axial position of the piston the magnet aligns the piston with ports 14, 20 in register.
