Title: Improvements in or relating to methods for producing ultra-pure substances, for example semi-conductor substances
IPC: C30B25/00
Filed: 1956-11-02
Abstract: In the production of silicon by reaction in the vapour state and deposition on a carrier consisting of silicon, the coated carrier produced is divided into at least two parts, at least one of which is employed as carrier for further deposition as aforesaid.  A carrier of uniform cross-section for first and/or further deposition may be produced from a rod by longitudinal cuts, the cutting planes being parallel to one another or intersecting one another at the axis of the rod.  The rod may alternatively be divided electrolytically with the aid of a jet of liquid.  The carrier may alternatively be produced by subjecting a rod to a combined drawing and zone melting process, the rod being previously or subsequently divided into shorter lengths.  A portion of the rod may be thus treated and separated from the remainder.  After production of the carrier it is preferably subjected to a surface cleaning by mechanical means, e.g. by sand blasting, or by chemical means.ALSO:In the production of germanium by reaction in the vapour state and deposition on a carrier consisting of germanium, the coated carrier produced is divided into at least two parts, at least one of which is employed as carrier for further deposition as aforesaid.

Title: Improvements in crepe threads and fabrics
Filed: 1936-12-10
Abstract: 486,868. Crepe threads and fabrics; embossing. DREYFUS, H., and DICKIE, W. A. Dec. 10, 1936, No. 33938. [Class 120 (iii)] [Also in Group XVI] Fabrics containing highly twisted regenerated cellulose threads which have been produced by a process in which at least the last part of the high twist is inserted while the threads are in a softened condition, are embossed so as to bring about displacement of the threads prior to subjecting the fabrics to the action of a crÛpeing liquid. The highly twisted threads may be obtained, for example, according to the process described in Specification 457,538, wherein the twisting takes place while the threads are under the influence of steam or hot water. Other softening agents such as cuprammonium solution, solutions of thiocyanates or of zinc chloride, or cold water, may be used. Twisting may take place on a device in which the thread is drawn off over the end of a rotating package, or a ring twister may be used. The floating ring device described in Specification 304,806, [Class 120 (ii)], may be used to restrict ballooning of the thread and the tendency of the twist to run back to the package. The total twist applied is in general less than is necessary to give a satisfactory crÛpe effect without the embossing treatment, for example a twist of 45 turns per inch is sufficient when embossing is employed, against 50-55 without the embossing step. The surfaces of the embossing rollers may have the appearance of a crepe fabric, or they may consist of small geometrical figures, or close patterns of continuous lines. The fabrics may be softened, e.g., by water, solutions of thiocyanate or of zinc chloride, or by steam, during the embossing operation. Specifications 348,589, 378,053, 424,683, 424,752, 424,830, 424,879 ; and 446,738, [Group VIII], also are referred to.

Title: Improvements in or relating to the manufacture of cable sheaths or the like
Inventor: LLOYD EDWARD THOMPSON
IPC: B21D15/06
Filed: 1959-10-07
Abstract: 896,163. Corrugating. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 6, 1960 [Oct. 7, 1959], No. 34008/59. Classes 83 (3) and 83 (4). Apparatus for forming circumferential corrugations on a cylindrical body, such as a cable sheath, comprises a head arranged to be rotatable relatively to said body, said head having an aperture through which said cylindrical body can pass, and a rotatable roller carrying a helical thread member, such as a ridge, arranged on said head to be in contact with said cylindrical body, the arrangement being such that the operative part of the helical thread member lies in a plane at right angles to the axis of said cylindrical body. Aluminium tubing 12 to form a cable sheath passes through a cylindrical body 13 on a rotated face plate 10. A corrugating roller 28, freely rotatable on a spindle carried by a bridge member 21 adjustable radially of the body 13 along flats thereon, has a helical ridge 30 thereon and projects through a window in the body 13 to engage the sheath 12. The axis of the roller 28 is skew to the axis of the sheath 12 so that the operative part of the ridge runs in a plane normal to the axis of the sheath where it contacts the sheath. Rotation of the plate 10 thus causes circumferential corrugations to be formed in the sheath. The roller 28 may have a controlled rotation about its own axis. A second contra-rotating corrugating head may work close to the first head so as to neutralize any twist in the sheath. In another embodiment, Fig. 3, a rotated face plate 41 carries skew supporting rollers 48, 49 and a skew corrugating roller 47. The corrugating roller may have a two or more start helix. A separate hauling device may pull the sheath through the corrugating head. Turning.-To produce a corrugating roll with a helical ridge a workpiece 55, Fig. 5, is mounted in an inclined position between offset centres 56 in a lathe and a cutting tool is reciprocated along the lathe.

Patent GB-521664-A (GB)
Title: Improvements in and relating to the treatment of textile materials
IPC: D06M15/05
Filed: 1938-11-24
Abstract: 521,664. Treating textiles. DRECHSEL, F. Nov. 24, 1938, No. 34212. [Class 15 (ii)] Textile material is treated in a stage preceding the weaving operation, e.g. when it is in flock or yarn form, by impregnation with a cuprammonium cellulose solution of a consistency approximating to that of machine oil at 20‹C., e.g. a viscosity between 500 and 3,000 without any previous treatment with alkali lye. It is then freed from excess of cellulose solution preferably by centrifuging or by suction, and the cellulose in the adhering solution is precipitated. The amount of adhering solution is such that adhesion between the individual fibres is avoided and in the case of yarns it is such that the yarns retain their filling and covering power. Textile materials which may be treated include cotton, regenerated cellulose, cellulose derivative fibres, or mixed fibres. Yarns receive a smooth surface free from fluff by means of the treatment. Cotton materials are given an increased dyeing capacity in respect of substantive or vat dyes. Artificial fibres are rendered more resistant to damage by bleaching and other subsequent treatment liquids. After the treatment with the cellulose solution the material may be subjected to treatment with alkali lye which has the effect of etching the fibres. The cellulose may then be regenerated by treatment with dilute acid. The cellulose solution may be prepared or adjusted so as to have the requisite viscosity by a protracted stirring preferably in presence of oxygen or by increasing the content of ammonia, or by reducing the amount of cellulose. Solutions containing 2-3.5 per cent. of cellulose and having the requisite viscosity are used for treating cotton yarn in cheese form, mixed yarn containing cotton and cellulose acetate or other cellulose ester or ether, and flocks of natural cellulose, regenerated cellulose, or cellulose derivatives. Specifications 435,642 and 468,694 are referred to.
