Title: Improvements in yarns
IPC: D01H5/36
Filed: 1959-04-07
Abstract: 905,954. Spinning yarns; roller arrangements in spinning machines. CELANESE CORPORATION OF AMERICA. April 7, 1959 [April 18, 1958], No. 11708/59. Classes 120 (2) and 120 (3). Yarn, comprising a core yarn, e.g. of nylon, rayon or acetate continuous filaments, with staple fibre, e.g. of acetate, triacetate and/or rayon, wrapped therearound and non-uniformly distributed to form slubs spaced along the length of the core, is made by supplying at least one roving of staple length fibre and a continuous yarn to a rotating forwarding member and periodically retarding the yarn to cause the member to slip relative thereto whereby the fibres pile-up about the yarn during slippage, and twisting together the yarn and fibres beyond the member. The member may draft the roving without breaking the continuous yarn. The slubs may be uniform or non- uniform in dimension and distribution. As shown, a creel 10 mounts rotatable bobbins 11 supplying rovings 12 which pass through a drafting device 13, comprising an apron 14 running on rollers 18, 19, control rolls 15, 16, weighted and rubber-covered roll 17, and front or draft rollers 20, 21. A creel 22 mounts a rotatable bobbin 23 supplying yarn 24 which passes through a guide 25 and feed rollers 26, 27, to the rollers 20, 21. The mechanism for driving the rolls 26, 27, e.g. a belt drive, Fig. 2 (not shown), or electric motor, may be braked and/or the transmission momentarily interrupted, as by means of a clutch or a switch, to cause slipping of the yarn 24 between rollers 26, 27: alternatively, the rolls 26, 27 run at constant speed, e.g. 20-50% slower than the peripheral speed of roller 20, and the yarn is first tensioned by a gate 43 and then passes through guides 44, 45, 46, the centre one of which is displaced periodically to lengthen the yarn path, Fig. 4. Composite yarn 29 from rollers 20, 21 passes through guide 28 to ring- spinning apparatus which winds a bobbin 33 of yarn in which bunched portions 30 are secured, as slubs 32, by the twist. As shown in Fig. 3, separate rollers 15, 16, 17, 20, 21, 27 at each spindle position may be replaced by beams 40 and 42, supplying rovings 12 and yarns 24 in sheet form, and rollers extending the length of a modified spinning frame.

Title: Cathodes for the electrodeposition of metal
IPC: C25D5/50
Filed: 1972-03-14
Abstract: 1323656 Coated cathode INTERNATIONAL NICKEL Ltd 14 March 1972 [17 March 1971] 11836/72 Heading B2E [Also in Division C7] A cathode, for the electrode position of metal thereon and subsequent removal of the deposited metal therefrom, consists of sheet metal presenting on one or both faces a resist pattern formed by a film of epoxy base paint cured by dicyandiamide, the film being separated from the sheet by a Cr plate. For use of the cathode in electrorefining metal (e.g. Ni), the resist pattern may comprise interconnecting areas or lines bounding discrete areas whereby the electrodeposited refined metal can be subsequently removed from the cathode as pieces. For use in electroforming foraminous products (e.g. Ni screens), the resist pattern is discontinuous, e.g. a system of dots, and the sheet metal cathode may be in the form of a rotating cylinder. The sheet metal of the cathode may be stainless steel, Ti, Al, Fe or Ni. The Cr plate may have been electroplated from a bath containing chromic acid and H 2 SO 4 . The epoxy resin used in the paint may be a mixture of glycidyl ethers of bis-phenol and may contain TiO 2 , CaCO 3  and SiO 2 . The parts of the Cr unmasked by the paint may have been removed by anodic dissolution in an aqueous solution of NaOH. When using the cathode in electrorefining Ni, the tendancy of the Ni to lift off the cathode during deposition may be reduced by depositing 0.005 to 0.025%S therewith from an electrolyte incorporating SO 2 . When depositing sulphur-free Ni, the cathode may first be roughened by grit blasting. Other specified metals which may be deposited are Co, Fe and Ni-Co.

Title: Improved process of and apparatus for balancing balls
IPC: A63B37/00
Filed: 1922-05-02
Abstract: 190,411. Arnott, R. F. May 2, 1922. Balls.-Comprises a method of balancing balls by injecting weighting material into the light side of the ball. The weighting material is preferably a molten metal alloy or mercury but other materials may be used. The ball 3, Fig. 1, is floated in a fluid 2 contained in a jacketed vessel 1 so that on coming to rest it has its lighter side uppermost and adjacent an injecting needle 14. By pressing down a pedal 9 the ball is raised on a cup 4 and pierced by the needle, the depth of insertion being controlled by two adjustable stops 6a, 6<b>. Weighting material 15 contained in a cylinder 17 is then forced through the needle into the ball by means of a plunger 21 coupled to a handle 28. The material is admitted to the cylinder 17 from a reservoir 1 on the up-stroke through a slot 23, Fig. 2, in the hollow piston stem 22, and a valve 24, supported by a float 26, in the plunger. When a melted material is used, hot water, steam, or the like is passed through the jackets surrounding the reservoir 16 and vessel 1 to maintain the material in its liquid state during injection, while a flexible protector 32 shields the needle itself. In a modification, Fig. 5, for use with normally-liquid materials, a simple plunger is used and the reservoirs are not jacketed. In order that the covers of the balls may be injured as little as possible, a pointed needle having a side outlet is used.

Abstract: 845,049. Statistical records. SIEMENS & HALSKE A.G. April 18, 1958 [April 18, I957], No. 12409/58. Class 106 (1). A statistical record has light-coloured spaces on a dark background and recording is effected by blacking-in selected ones of the spaces. In the form of Fig. 1 the record consists of columns of spaces on a dark background, each containing a digit signifying its value and the space containing the appropriate digit is filled in with a pen or pencil so that a photo-electric sensing device does not respond to the space. The signals produced therefore compiise a train, or say, nine regular pulses, with a gap representing the blacked-in tenth position. An absorbent paper may be used, e.g. blotting paper, to help the blacking-in process when ink is used. The digits may be printed in an ink which repels the recording ink to allow the digit to remain visible after blacking-in. The digit may be printed as part of the dark background and provided with a light coloured space along side as shown in Fig. 2. This record may be sensed in the direction of the rows to save accurate alignment. In another form, Fig. 3, the space is disposed across the digit. In a further form the space is itself shaped as the digit and the digit is still legible after blacking-in.
