Title: Improvements in highly stretchable yarn
IPC: D02G3/32
Filed: 1945-06-01
Abstract: 595,439. Elastic yarns. UNITED STATES RUBBER CO. June 1, 1945, No. 13781. Convention date, Aug. 5, 1944. [Class 120 (iii)] An all textile high stretch yarn comprises a crepe yarn coiled helically about a central axis in the direction of its crepe twist. The crepe yarn may be a single yarn with a crepe twist or two or more single yarns plied together with a crepe twist. In one embodiment, Fig. 1, a crepe yarn 10 comprising two single yarns 11 plied together with a crepe twist is coiled helically about a central core 13 which may be weak enough to break easily when the yarn is stretched, or may be chemically destroyed. The crepe yarn may for example be of cotton or viscose rayon, and the core of cellulose acetate which can be dissolved in acetone. In the relaxed condition the number of coils/in. is preferably greater than the crepe twist. A balanced form of yarn, Fig. 4, is produced by cover-winding a yarn 10 as in Fig. 1 with a second crepe yarn 14, the twist of which is in the opposite direction to that of yarn 10, the helical coils 15 being opposite in direction to coils 12. An alternative balanced yarn, Fig. 7, comprises two yarns as in Fig. 1, plied together. the ply twist being in the opposite direction to that of the helical windings 12. The core or cores 13 may be retained whilst the yarn is woven, knitted, etc., and subsequently broken or destroyed. The yarn may have an extensibility of 50-300 per cent. Known apparatus, as in U.S.A. Specification 1,982,208, may be used for forming the coiled yarn without a central core.

Patent GB-592880-A (GB)
Title: Improvements in the anti-felting treatment of materials consisting wholly or partially of wool
IPC: D06M11/38
Filed: 1945-06-02
Abstract: Wool fibres or materials consisting wholly or partly of wool fibres, e.g. yarns and fabrics, are rendered resistant to felting and shrinking by subjecting them to the action of a saturated or substantially saturated solution of caustic alkali in ethyl or methyl alcohol diluted with an organic non-solvent, or poor solvent for caustic alkali, which is miscible with the alcoholic solution.  The reagents should preferably not contain more than 2 per cent of water, but the water content of the wool being treated may be 12-18 per cent.  The treatment may be carried out at 15-20 DEG  C.  The concentration of alkali in the organic liquid mixture is such that when the temperature of the solution is raised to 30 DEG  C., separation of solid caustic alkali as a fine dispersion may be seen. In an example, a 1.1 per cent caustic soda solution (weight/volume) in a mixture of ethyl alcohol, one volume, and trichlorethylene, nine volumes, is prepared and knitted wool fabrics are immersed in the solution for one hour. Instead of trichlorethylene, the diluent may be white spirit.  In another example, scoured wool is treated with a solution made by mixing 10 volumes of 11 per cent caustic soda solution in ethyl alcohol with one volume of cyclohexanol and 89 volumes of white spirit.  After the treatment, the alkali and organic liquid is removed by centrifuging, washing with dilute sulphuric acid, neutralizing and drying.  The treated materials are resistant to felting.  Specification 538,711 is referred to.

Title: Method of picking up a spill on water of a liquid hydrocarbon oil
IPC: H02H3/38
Filed: 1973-03-23
Abstract: 1422999 Removing oil from water GRANTLEY CO 23 March 1973 [23 March 1972] 14034/73 Heading C1C A method of picking up a spill on water of a liquid hydrocarbon oil comprises absorbing the oil on crumbs of foamed polystyrene of normally closed cell type of which the cells have been opened up by shredding a multi-cellular mass of the polystyrene of density 1À4-2À0 lb/cu. ft. and average cell size 1À0-3À0 mm., the crumbs being of a size passing through a ¥-inch mesh screen but being retained by a -inch mesh screen. The polystyrene must have a selective absorption for oil when subjected to a mix of oil plus water, must not soil on contact after absorbing a saturated load of crude oil out of a bath of water, and must absorb about 19 times its weight of crude oil. The polystyrene sold under the name of "Styrofoam" (Registered Trade Mark) D.B. brand satisfies all these requirements. It is preferably treated to make it fire retardant, e.g. by immersion in 5% aq. boric acid solution followed by drying. Sometimes it is desirable to soak the polystyrene in water before applying it to an oil spill. When the oil is floating as a layer on water the crumbs are preferably applied by forcing a stream-like jet of them into the oil layer. After application to the spill a P.V.C. solution, e.g. in a solvent such as methyl ethyl ketone, may be added to the layer of saturated polystyrene crumbs to aid in their agglomeration. To recover the oil from the saturated crumbs they may be treated with a solvent such as methyl ethyl ketone, methyl isobutyl ketone, acetone, benzene, toluene, xylene, carbon tetrachloride, perchlorethylene or trichlorethylene. In addition to the removal of oil from a spill in the open sea or other body of water, the method may also be used for example to remove oil from contaminated sand and water (by mixing the polystyrene with the sandy oil and water followed by washing the mixture with water to remove substantially oil-free sand from the oil-saturated crumbs); or the crumbs may be used as a filter to pick up oil from an oilwater mixture, e.g. in the treatment of a discharge from ships' bilges and from the flushing of tankers and barges or in the treatment of cutting oil or emulsified oil.
