Patent GB-695536-A (GB)
Title: Improvements in or relating to apparatus adapted for use in manufacturing synthetic fibres
IPC: D01F6/18
Filed: 1949-12-28
Abstract: <PICT:0695536/IV (a)/1> Apparatus for manufacturing synthetic fibres comprises means for producing the fibre or fibres in gel form, a rotary device for receiving and supporting the fibres and advancing them in a helical path, means for wet-stretching the fibres in the gel state after they leave the take-off end of the rotary device, a second rotary device for receiving and supporting the stretched fibres and to advance them under tension in a helical path toward the take-off end, a device for drying the stretched fibres while they are travelling round the second rotary device, a heating device arranged to receive the fibres from the take-off end of the second rotary device, means for moving the fibres through the heating device, and means for relaxing the tension on the dried fibres so that they are free to contract linearly as they pass through the heating device. The first and the second rotary devices may each be comprised of a pair of spaced cylindrical, converging rolls, each pair being suspended in the same vertical plane.  The term "fibre" includes both monofilaments and multifilaments.  The fibres may be produced by extruding a solution of a polymerization product, such as an acrylonitrile polymer, into a coagulating liquid.  The apparatus may be used in carrying out the process of Specification 695,448.  As shown, synthetic fibres are obtained by extruding a solution of a polymerization product through nozzle 14 into a cooled aqueous coagulating liquid 22 in bath 24. The fibres pass under submerged roller 120 and then upwardly and out of the bath to a pair of mutually inclined rollers 124, 126, which they traverse axially in helical turns and on which they are washed by cooled water from jet 128.  If desired the rolls 124, 126, may be cooled internally.  The washed fibres are stretched by passing them round godet 38, then through hot aqueous liquid in trough 42 and thence over godet 44 which has a greater peripheral speed than the godet 38.  The stretched fibres pass in helical turns round a pair of mutually-inclined drying cylinders 70, 72. An anti-static liquid preparation is applied by jet 136 to the first few turns of the fibres.  The dried fibres pass through a heating zone provided by a groove in a metal block 82 which is heated electrically.  The godet 76 has a lower peripheral speed than rollers 70, 72, so as to allow the fibres to contract during the heat treatment.  Slippage of the fibres over godet 76 is prevented by means of the weighted pinch-roll 92.  The fibres pass under tension from godet 76 to a ring-twister 86.  Specifications 594,999 and 672,775 also are referred to.

Title: Improvements in or relating to the manufacture of rubber or the like tubes and apparatus therefor
IPC: B29C48/09
Filed: 1928-04-04
Abstract: 314,600. Dunlop Rubber Co., Ltd., Hall, J., and McCombe, G. F. April 4, 1928. Extrusion machines.-Annular articles of rubber or rubber compounds are formed by extruding the material through a die adapted to cause the material to exude more rapidly at one side than the other and assume an annular form. Fig. 1 shows a die for even-walled tubes wherein the core 2 is furnished with a protuberance 1 to retard the flow at the side 5<b> relatively to that at the other side 5<a>. A similar die, with a larger protuberance, is described for the production of tubes having a thickened base. The protuberance may be on the die wall; alternatively either core or wall may be furnished with a cavity to increase the flow at one side, e.g. as shown at 18, Fig. 9, in a die for producing solid articles. Fig. 10 shows a modification wherein the die is of arcuate form, the flow being retarded by the longer path 19. In a further modification, the flow at one side is retarded by offsetting the die relatively to the extruder screw. The extruded articles may be received upon a rotary support, e.g. a horizontal tray 6, Fig. 3, or a vertical drum 11, Fig. 5. As shown in Fig. 3, the length extruded may be gauged by a stop 14 and scale 15. Preferably the supports are removable, the article being allowed to cool thereon. Fig. 13 shows a modified support adapted to receive a spiral length. According to the second Provisional Specification, straight tubes having a thickened base may be similarly produced.

Title: Application of surface patterning to rigid and flexible sheet materials
IPC: B05D1/20
Filed: 1961-03-22
Abstract: 951,954. Coating surfaces. H. R. BURGESS. March 19, 1962 [March 22, 1961], No. 10386/61. Heading B2B. [Also in Division D1] Sheets of rigid material (e.g. glass) and sheets or continuous lengths of flexible material have a decorative patterned effect applied thereto by passing the material through the surface of a pool of water on which surface floats colouring, filler and transparent breaker elements. The material may be precoated with varnish.

Title: Fibrous tubular structure and process for making same
IPC: B29C53/56
Filed: 1963-03-15
Abstract: 974,453. Pipes and tubes. E. I. DU PONT DE NEMOURS & CO. March 15, 1963 [March 16, 1962], No. 10469/63. Heading F2P. A process for preparing a fibrous tube comprises winding a plurality of layers of sheets or strands composed predominantly of crystalline oriented film-like polymer elements around a mandrel to form a tube, compresssing the tube wall and heating the tube to weld the film-like elements together at their cross-over points without destroying the crystalline orientation of the filmlike elements at the centre of thickness of the tube wall. The film elements used have a thickness of less than 4 microns, and may be made by direct lay-down of plexifilaments on a moving belt or by cutting and beating plexifilaments in aqueous suspension and forming sheets on a screen. Plastics used are branched polyethylene, linear polyethylene polypropylene, poly- (ethylene terephthalate) and poly(hexamethylene adipamide). The sheet may be wrapped helically or normal with respect to the axis of the mandrel. The pipe may be coated on the exterior or internally lined with a water-impermeable resin containing an ultra-violet screener, carbon black or other fillers. In one example plastics material from an autoclave 101 was passed, under pressure, through a filter 103 to spinneret assemblies 110 where the plastics was extruded to impinge against a deflector 22 where the extruded strand was spread out into a wide network of filmfibrils 106 (Fig. 3) which passed through an electrostatic field 107 to improve separation and to help the fibrils to adhere to a moving belt 108 resting on a ground plate 109. Random deposit of the fibrils on the belt was enhanced by oscillating the deflector. The fibrils were passed under a static dissipator 111 and through pressure rolls 112 to produce a sheet which was wound on to roll 115. Several layers of the sheet were wound on a mandrel then removed intact to be placed in a steam jacketed cylinder 2. An expandable tube 3 was inserted in the plexifilamentary tube 4 and made air-tight by clamping it between flanges 5. Air pressure was supplied to the tube 3 and vacuum to the space between the plexifilamentary tube 4 and the wall 8 of the cylinder. The air pressure was then released and steam under pressure supplied to the cylinder 2 through inlet 12 and to the tube 3 through inlet 6. Heat and pressure were supplied to weld the fibres together at their cross-over points without destruction of the fibres or of their orientation. The cylinder was cooled by water introduced through pipe 11, air pressure released and the finished tube was removed. A rigid mandrel with external pressure rollers can be used to apply pressure to the plexifilamentary tube and electrical heating can be used.

Abstract: 986,749. Rollers. CONTINENTAL CAN CO. Inc. March 12, 1964 [March 19, 1963], No. 10528/64. Heading F2U. An expanding roller for winding webs of paper comprises two semi-cylindrical members 20, 21 engaged along their edges and carried by mounting plates 36, 37, inclined cam surfaces 46 on wedging blocks 38, 40 secured to the mounting plates coacting with similar surfaces 91 on a hollow shaft 11, so that when a control rod 57 is pulled rightwards of Fig. 3 to act through a transverse thrust plate 54, the semi-cylindrical members are slidden along the hollow shaft and accordingly wedged apart. Compression springs 58 surrounding free rods 60 act through brackets 63 on the semi-cylindrical members 20, 21 to bias the two latter towards each other. Interdigitating teeth 23, 24 are provided along the engaging edges of the two semi-cylindrical members 20, 21. The hole in the wedging blocks 38, 40 and the coacting tapered surfaces on the spindle 11 are, when viewed axially, of square shape, so that rotation of the spindle causes the roller 20, 21 to rotate. Axial movement of the control rod 57 to expand the roller is effected by energization of a solenoid, Fig. 1 (not shown), and the spindle 11 is rotated by an electric motor driving through belt and pulley gearing. A line of holes 28 along the surface of the semi-cylindrical member 20 is connected through a duct 27, a pipe 30 and a gland (not shown) on the hollow shaft 11, to a source of low pressure; the end of a paper web can thus be held to the roller at the beginning of a winding operation.
