Title: Embossed tufted carpet and process for its manufacture
IPC: D06C23/04
Filed: 1974-05-10
Abstract: 1475143 Finishing fabrics ARMSTRONG CORK CO 10 May 1974 20771/74 Headings D1K and D1S An embossed tufted pile fabric is produced by printing a pattern on a tufted pile fabric with a liquid comprising a solvent for at least one of the constituent fibres of the fabric; steaming the fabric to shrink the fibres within the tufts where they are affected by the solvent and to soften the outer surfaces of the individual fibres so that they adhere to each other without loss of their fibre identity; and washing and drying the fabric. The solvent may be deposited in an ink on the fabric by rotogravure, intaglio, flexographic, flat or rotary screen printing techniques. The ink may also contain a dyestuff which may be set on the fibres during steaming. The solvent printing may be combined with a conventional printing operation in other areas of the fabric. As shown in Fig. 1, the ink is applied to the face of a carpet 8 by a pattern roll 4 backed by a roll 6. The carpet 8 passes through a chamber 12 which applies steam at 212-220‹F, through a wash tank 14 and through a dryer 16. The steam causes the individual fibres within a strand to shrink and to be partially bonded together due to the action of the solvent but to retain their fibre identity with nodules (18), Fig. 2 (not shown), formed thereon, and tend to maintain the loop configuration of the tufts. Ethylene carbonate is a specified solvent for a fabric containing acrylic fibres, resorcinol for nylon fibres, aqueous phenol for polyester fibres and aqueous sodium hydroxide for wool fibres.

Title: Improvements in and relating to the production of artificial threads, fibres, filaments and the like
Inventor: BENNETT ALBERT WALTER
IPC: D01F6/18
Filed: 1952-08-25
Abstract: Artificial threads, fibres, filaments and the like of a polyacrylonitrile are obtained by extruding a solution of the polymer in a concentrated aqueous solution of a water-soluble salt, which yields highly hydrated ions in aqueous solution, into an aqueous coagulating bath in which at least 5 per cent by weight of the water-soluble salt is dissolved, and which also contains a water-miscible alcohol such as methanol or ethanol, preferably in a proportion of at least 5 per cent by weight of the coagulating bath. The coagulating bath may be used at a temperature of 10 DEG  C. or lower, or at a higher temperature, e.g. 15-25 DEG  C. or up to 40 DEG C.  The water-soluble salt employed in the spinning solution and in the coagulating bath may be zinc chloride, calcium chloride, lithium bromide, calcium bromide, calcium iodide, zinc nitrate, calcium nitrate, aluminium perchlorate or a thiocyanate of sodium, calcium or zinc.  An organic salt such as guanidine thiocyanate may be used.  To avoid undesired increase in the concentration of the salt in the coagulation bath, aqueous alcohol may be added to the bath during the course of a continuous spinning operation.  In an example, a copolymer of acrylonitrile (90 per cent) and methyl acrylate (10 per cent), having a molecular weight of about 100,000, is dissolved in a 50 per cent aqueous solution of calcium thiocyanate to form a 7 per cent solution of the polymer.  The solution is extruded into an aqueous solution containing 10 per cent of calcium thiocyanate and 10 per cent of methanol.  The threads obtained are washed with water stretched in steam, and allowed to relax while heated.  Part of the wash water is added to the coagulating bath and methanol is pumped in to maintain the bath composition substantially constant.  Calcium thiocyanate is recovered as a solution from the used coagulating liquid by distillation to remove firstly the methanol and then sufficient water to give an aqueous solution for use in dissolving fresh polymer.  Specifications 459,596, 672,775 and 715,915 are referred to.

Abstract: 614,510. Automatic circuit-breakers. LANDIS & GYR SOC. ANON. July 17, 1946, No. 21442. Convention date, Aug. 1, 1945. [Class 38 (v)] An automatic circuit-breaker is tripped by the action of a bimetallic strip 20 which joins moving contacts. 19 mounted on a sliding frame 2 within the body 1. A flat strip 3 is free to slide within the frame 2, but may be locked to it by means of a projection 4 abutting a T- shaped catch 21, which has a rod 23 bearing on the bimetallic strip. A contact-pressure spring 7 is placed between shoulders 5 formed on the strip 3, and a press-button 6. The end of the strip 3 is bent over at 8 to overlap a rod 9 fixed within the button. In the position shown the circuit-breaker is closed and when an overload occurs the bimetallic strip moves the catch 23, 21 clear of the projection 4 so that a spring 27 forces the sliding frame upwards to break the circuit. The sliding frame then strikes a projection 14 on a stirrup 12 causing it to pivot about pins 10 to release the rod 9 from books 13. The push-button 6 is then forced up into the " off " position by springs 18, causing the rod 9 to lift the strip 3 to reset the projection 4 on the catch 21. The circuit breaker is re-closed by pushing the button down so that the contact pressure spring pushes the strip 3 and sliding frame 2 down to close the contacts 19, 25, the button being held down by the re-engagement of the rod 9 with the hooks 13, which are moved back into position by the action of spring 18 pushing on a plate 15 which bears on the stirrup 12 by means of a short lever. A screw socket may be provided in lieu of the plug-pins 26.
