Title: Process and apparatus for the manufacture of crimped bulky filament
IPC: D02G1/16
Filed: 1970-01-27
Abstract: 1316440 Crimping fibres TEIJIN Ltd 27 Jan 1970 [27 Jan 1969 22 May 1969 23 May 1969 24 May 1969 26 May 1969 12 June 1969] 4011/70 Heading D1F In a process for preparing crimped bulky filaments, e.g. of a polyamide or a polyester, by impingement thereof in at least one heated jet stream upon a perforated moving surface through and on which the stream passes and the crimped, cooled filaments are retained, at the point where these filaments are subsequently separated from the surface a pushing action is exterted on the filaments thereby to maintain the point stationary. This ensures uniform crimp during any selected process despite unwarranted change and variation in operating conditions, e.g. feed and take-off tensions. As shown in Fig, 1A, filaments f are fed at constant speed to, and are projected from, a jet 6 in a heated fluid stream to impinge on a rotating screen disc 7, plasticised crimped filaments are cooled and set as they move with the disc and the separating point therefrom is formed by a free or driven conical pressing roll 1. If the screen is in the form of an endless belt, the pressing roller is cylindrical. The function of such roll 1 may be performed by an apron roller, a pressing or snubbing rod or an air suction pump (not shown). Laminar flow without turbulence of a compressed fluid is ensured by use of a jet such as shown in Fig. 3A wherein a hollow needle 15 for passage of the filaments extends through a chamber 2, into which the fluid is injected, and projects into the outlet passage 2' sufficiently to form an annular passage 2" for the fluid, some counter flow of which is permissible. An additional jet may project another heated stream, e.g. of air, onto the plasticised filament left on the screen. The screen may comprise at least two adjacent overlapping layers, e.g. as described in Specification 1,273,797, wherein a stuffer crimping action may occur additionally within the depth of the screen. The end outlet parts of the jet(s) may be composed of, or be coated with, material such as ceramic or polytetrafluoroethylene of high temperature resistance and low thermal conductivity to discourage formation of fused obstructions or dregs.

Title: Improvements in or relating to the manufacture of cellulose from ligno cellulosic materials
IPC: D21C9/08
Filed: 1936-02-11
Abstract: In a process for the manufacture of cellulose, spruce, poplar, pine or other wood or other lignocellulosic material, e.g. chemical pulp or semi-pulp is immersed in a dilute alkali solution at a temperature not substantially in excess of room temperature, chlorine is passed through the solution, and the material is then heated with a further alkali solution.  If desired some chlorine may be added to the dilute alkali solution before immersion of the material.  The material may be softened before chlorination, e.g. by boiling with a dilute alkali solution, or with water under atmospheric or higher pressure.  The more resinous types of wood may be treated with cold dilute alkali or an organic solvent, e.g. turpentine to remove resin, or the resin may be removed by the softening treatment.  The alkali solution of the first treatment may be caustic alkali of less than 5 per cent.  Other alkalies, e.g. sodium carbonate or lime may be used in place of or as well as caustic alkali, the alkalinity being equivalent to a caustic soda solution of less than 5 per cent.  The amount of alkali used depends on the nature of the material.  A moderately resistant wood, e.g. spruce may be treated with 8--12 or more times its weight of solution.  Preferably, the pressure is atmospheric or greater.  The after-treatment may be carried out by boiling under atmospheric pressure with dilute alkali, e.g. of the same concentration as that employed in the chlorination.  The chlorinated material may be boiled with a 1 or 2 per cent solution of sodium sulphite to which caustic soda is added either initially or during the boiling or a simple caustic soda solution may be used.  The after-treatment may be at superatmospheric pressure and at or below the boiling point of the solution at that pressure. The material may then be given a final bleach.  When the product is to be used for organic esters of cellulose it may be treated with a lower aliphatic acid as described in French Specification 565,654 or with the vapours of such acids as described in British Specification 263,938, [Class 2 (ii)].  In an example, spruce or poplar chips are softened by a short open boil in dilute caustic alkali and are washed.  They are immersed in cold dilute caustic alkali containing about 2,5 times its volume of chlorine, and chlorine is passed through for 2 hours.  The product is again washed and subjected to an open boil with dilute sodium sulphite solution for half an hour, dilute caustic soda being added after 15--20 minutes.  The same treatment may be applied to a sulphite semi-pulp with a lignin content of 8--10 per cent.  The length of the caustic soda-chlorine treatment may be reduced to 1\ba1/4\be--1\ba1/2\be hours.

A reversible motor 54 drives a spindle 40 which carries a sleeve 39. The sleeve is prevented from rotation with the spindle by engagement  with member 38, Fig. 2, but is adapted to move along the spindle as the spindle rotates between stops 42, 43. The sleeve abuts a stop on member 38 when it moves to the right so that it may retract the gauge pin 1, but may move out of engagement with the member 38 as it moves to the left if the member 38 is prevented from further movement by abutment of pin 1 with a measured object. Grid 2 co-operates with grid 57 and photoelectric means 58 to provide a digital output. The tube 37 is adjustable both longitudinally and rotatably during manufacture so that the scale or grid 2 may be precisely aligned, the tube 37 then being clamped in position.
