Title: Improvements in or relating to the production of artificial filaments, foils, films and like materials
IPC: D01D1/04
Filed: 1940-02-03
Abstract: 540,967. Artificial filaments, films &c. DREYFUS, H. Feb. 3, 1940, No. 2142. [Class 2 (ii)] Artificial filaments, bristles, foils, films, and like materials are obtained by bringing a thermoplastic composition (other than a cellulose acetate composition), which is substantially free from volatile solvents to a substantially uniformly fused condition by feeding it through a heated narrow tube which communicates directly with an extrusion orifice, and extruding and setting the resulting fused composition. The tube may be made of or lined with tin, silver, tantalum, aluminium, copper, chromium, or stainless steel. The process is applicable to the production of filaments or films having a basis of a polyamide formed by self-condensation of an amino-carboxylic acid or by condensation of a diamine with a dicarboxylic acid, or having a basis of other superpolymers, or of cellulose derivatives (other than cellulose acetate) such as the butyrate, or acetobutyrate, or methyl, ethyl, or benzyl cellulose ether, or of polyvinyl esters or ethers, or polyacrylic or polymethacrylic acid esters. The filament or film-forming compositions may contain solvents, softening agents, pigments, or dyes. The heating tube may be provided with an electrical heating coil or a fluid heating bath. The heating fluid may be gaseous, vaporous, or liquid, and it may be a paraffin, arylated paraffin, acenaphthene, anthracene, benzene, diphenyl, toluene, dibenzyl, naphthalene, dinaphthyl, phenanthrene, tetraline, isoamyl ether, dimethyl ether of ethylene glycol, anisole, ethyl benzyl ether, dinaphthyl ether, diphenyl ether, halogenated substitution derivative of a hydrocarbon or ether, or nitrogen, hydrogen, or carbon dioxide. The thermoplastic composition may be fed to the narrow tube as powdered material through a hopper or it may be fed or drawn in partially fused or semi-plastic condition from a heated vessel into a hopper connected with the tube or directly into the tube. The hopper or vessel feeding the tube may be employed as the chamber in which part or the whole of the re-action for producing the thermo-plastic substance is carried out. The extrusion may take place under gravity or pressure may be applied by means of an inert gas or liquid. The extruded materials may be drawn at a speed many times that of extrusion. Specification 529,510 is referred to.

Filed: 1972-01-17
Abstract: 1323652 Hydraulic actuator systems ROBERT BOSCH GmbH 17 Jan 1972 [3 Feb 1971] 2212/72 Heading F1P An hydraulic system comprises an hydraulic pressure pulse generator 1 providing pressure pulses to an hydraulic actuator 3 through a fluid conduit 2, the pressure transmitted being controlled by a control device 20 having a cylindri cal bore 21 which defines an expansion chamber and in which a piston 22 can reciprocate. When the piston 6 of generator 1 is moved by cam ring 9 the increase in pressure is initially taken up by piston 22 against the action of a light spring 23, until the rod 25 of piston abuts an adjustable stop 28. This stop 28 is loaded by a relatively stiff spring 29 and there is a rapid build up of pressure which is transmitted to the actuator 3. Thus, by varying the position of stop 28 and the resistance of spring 29, the hydraulic pressure transmitted can be varied with the stroke of the generator piston 6 remaining constant.

Abstract: 751,968. Making cemented pile fabrics. BRINTONS, Ltd. Jan. 14, 1955 [Jan. 26, 1954], No. 2376/54. Class 142 (4). In a machine for making carpets by sticking pile tufts on to a backing as described in Specification 703,075, the lengths of yarn to form the tufts are withdrawn from tuft yarn spools before the spools reach the position at which the tufts are applied to the backing; to ensure equal and constant braking of all the spools whilst yarn is being drawn off, a brake is then applied directly to the yarn mass on the spool, the individual spool brakes being put out of action. As shown, yarns 8 are drawn from two spools 4 simultaneously by grippers 61 which reciprocate beneath the spool frames 2 attached to a continuously moving conveyer chain 1; the grippers rise to grip the yarns, then move to the right in synchronism with the conveyer, at the same time descending to draw yarn from the spools; at the end of their horizontal travel, the grippers open and return to the left to operate on the next two spools. The movable jaws of the grippers are attached to levers 64 pivoted at 62 on a carriage 12, and have rollers 68 running in stationary cam grooves 69 which cause the carriage to rise and fall as it is being moved horizontally by links 66, 71 operated by an oscillating lever 65 ; opening and closing of the jaws is effected by a pneumatic cylinder 76 which imparts additional movement to the link 71, thereby turning the levers 64 about their pivots. The cam grooves 69 are formed in members 83 which can be turned about pivots 84 to adjust the length of yarn drawn from the spools. Brake shoes 50 pivoted at 51 on the spool frames and normally pressing against the flanges of the spools to prevent accidental rotation, are released by encountering a fixed abutment when the grippers operate on the yarns, and brakes 14 are applied instead. Each brake 14 consists of a bar which presses on the surface of the yarn mass on the spool, whereby the braking force is made independent of the amount of yarn on the spool. The bars 14 are carried by levers 15 pivoted at 16 on a carriage 21 which is reciprocated by an oscillating lever 22, rocking of the levers 15 to apply and release the brakes being effected by a pneumatic cylinder 38 acting on a rod 31, the braking force being determined by springs 33 on the rod. Specifications 722,260, [Group XXII], and 751,969 also are referred to.
