Title: Improvements in and relating to the production of viscose rayon threads
IPC: D01F2/06
Filed: 1948-05-24
Abstract: Artificial threads are produced from viscose by extruding viscose into a coagulating bath and subjecting the thread thus formed without any break to liquid treatment and to drying and winding on to a package wherein a liquid containing a bleaching agent and which will be destroyed, before any appreciable degradation of the cellulose occurs, by reaction with impurities present and by heat under the conditions prevailing immediately preceding and during the drying step, is applied to the thread and the thread containing the agent is dried.  The preferred bleaching agent is chlorine which may be in the form of an aqueous solution of chlorine or of a hypochlorite such as sodium hypochlorite, or may be an aqueous suspension of calcium chloro-hypochlorite (bleaching powder).  The bleaching liquid may also contain a mild alkali and/or a small proportion of a soft finishing agent such as an emulsified oil.  The liquid may contain from below 20 to over 100 parts, e.g. 500 parts, per million of available chlorine.  In an illustrated example viscose is extruded from a jet 1 into a coagulating bath 2 containing sulphuric acid, sodium sulphate and zinc sulphate to form a thread which is withdrawn from the bath by a thread-advancing reel 5 and passes from thence over a series of thread-advancing reels 6, 9, 12 and 15 arranged in echelon and driven by gearing 18.  The thread 4 is treated on reel 6 with an aqueous 1 per cent sulphuric acid solution at 85 DEG  C. <PICT:0645969/IV (a)/1> applied from the pipe 7, the used liquid being collected in the drip pan 8, and similarly on reel 12 with an aqueous bleaching solution at 25 DEG  C. containing 0.02 per cent of sodium bicarbonate and an amount of sodium hypochlorite equivalent to 25 parts of available chlorine per million parts of solution.  The thread is then passed immediately to a steam-heated drying reel 15 at 110 DEG  C. and finally collected on a cap-spinning device 17.  Prior to the application of the bleach solution the thread may be washed on the reel 9 with hot water.  The bleaching agent may be partially removed by a washing treatment before the thread is dried.  Data are furnished showing the effect on the tensile properties of threads of bleaching with various concentrations of available chlorine. Specifications 413,413, [Group IV], 413,414, [Group IX], 474,973, [Group IV], and 645,171 are referred to.

Title: Improvements in carpet pile knotting machines and mechanism
IPC: D03D39/02
Filed: 1929-05-04
Abstract: 311,232. Boyer, F. May 7, 1928, [Convention date]. Pile-fabric looms; vertical looms. - Relates to pile-knotting mechanism for carpet-making machines and comprises means whereby the movement of the pile knotter or pile-thread gripper is a simple forward and backward one. In the machine described, the two ends of the pile thread are gripped and drawn around the pair of warp threads by a single backward and forward movement of a holder which rotates to present the pile thread to a knotter which thereupon completes and tightens the knot by a single backward and forward movement. A pile thread 2, Fig. 3, is swung towards the vertical warp threads 1 by a known form of pile thread feeder, the ends of the thread then being seized by grippers 9 which move forwardly through the warps, engage the ends of the pile, withdraw them around the warps 1, Fig. 10, and secure them against a sleeve 3, the motion of the grippers 9 being effected by a bracket 10 in which an extension 7 of the grippers is rotatably mounted. The grippers, which are slidable in a slot in the sleeve 3 are then rotated through 180 by a rack 12 in engagement with a pinion 11 on the sleeve which is mounted on the limbs 4, 5 of a carrier 6. The ends of the pile knot are thus moved into the position shown in Fig. 12. A knotter carrier 17 is then moved into the position shown in Fig. 3, its hook member 19 moves relatively to the abutment member 18 and passes between the pair of warp threads 1 around which the ends of the pile thread 2 are twisted as shown in Fig. 12, so that, when the knotter is withdrawn, the ends of the pile thread are drawn through the warps, and the knot is completed as shown in Fig. 13. The grippers 9 then rotate back through 180 and the parts resume their initial postions. The grippers and knotters are mounted on screw-operated slides which may traverse a number of the knotforming devices across the warps, or a large number of the knot-forming devices may be employed in which case, the traversing movement is reduced or dispensed with.

[Class 82 (ii)] [Also in Croup XXXVI] In a method of flowing a metal coating applied to a metal strip, the coated strip is continuously moved through a liquid flux heated to a temperature below the melting- point of the coating metal, heated by passing an electric current through it to melt the coating and finally quenching the strip in a cooling liquid, the length of strip between the flux and cooling liquid being enveloped in a non-oxidizing atmosphere. As shown, the strip 12 passes under a roller 10 in a flux bath 1 heated by an electric resistance 18 to a temperature just below the melting-point of the coating metal, over a roller 7 in a tower 3 and then under a roller 11 in a water tank 2. The rollers 10, 7 and 11 are connected to the secondary of a transformer 13 and supply electric current to the strip. The temperature of the strip may be controlled by the co-operation of a pyrometer 17 with the transformer. A hood 20 removes the steam formed by the quenching and prevents contamination of the non-oxidizing atmosphere.
