Title: Improvements relating to clutch devices for use in connexion with winding engines and the like
IPC: B66D5/00
Filed: 1920-02-10
Abstract: 163,107. Llewellyn, A. Feb. 10, 1920. Clutches, claw; securing winding-drums on shafts.-Relates to positive clutches or couplings for use especially with mine-shaft cage-winding machinery, in which one winding-drum is permanently secured to the engine-shaft and a second drum is attached to the shaft by the clutch or coupling so that the drums, which operate cages moving in opposite directions, may be separately adjusted to provide for changes of level in the mine. A sleeve b secured to the engineshaft a carries a large number of teeth differing in number slightly and preferably by one from teeth on a member d on the winding-drum c. A clutch-ring e sliding on a flange f on the sleeve b has teeth or groups of teeth corresponding to those of the parts b, d and has a circumferential groove o engaged by levers k also engaging pistons l in cylinders g supplied with air, water, oil &c. under pressure from annular pipes q, r controlled from a head u by a two-way cock etc.; compressed air may be exhausted to the atmosphere. When relative adjustment of the cages is required, the drum c is braked with its cage fully raised and the ring e is withdrawn to the position shown by the fluid-pressure means described or by mechanical means which may be substituted therefor and the shaft a and sleeve b are rotated to adjust the other cage. The ring e is then rotated by hand or by a tommy bar &c. to a position such that its teeth register exactly or nearly exactly with those on the parts b, d. This action is facilitated by providing a knob or mark on the ring e where the inner and outer teeth are directly opposed or at some other suitable position. The ring e may then be pressed to position between the parts b, d even though there is not exact register, sufficient tooth clearance being provided for this purpose, or, alternatively, the leading edges of the ring teeth are so tapered that pressure on the ring will cause slight relative rotation of the parts b, d. The ring e may be locked in clutching position, for instance by stops screwed into the flange f.

Title: Method for preparing a spinning solution from waste arising during the production offibres of acrylonitrile polymers or copolymers
IPC: D01F6/18
Filed: 1965-01-29
Abstract: Spinning solutions are prepared from waste materials, arising during the production of fibres of acrylonitrile homo- or co-polymers from spinning solutions whose solvent is an aqueous solution of a suitable inorganic salt, e.g. sodium thiocyanate, by a process wherein the waste material comprising coagulates of the original spinning solution, or waste fibres, still containing 0.1 to 15% by weight of said salt is comminuted or cut into short chips, dried at 40-130 DEG C., added to a cooled organic solvent suitable for preparing spinning solutions from said polymers, allowed to swell for 0.5 to 20.0 hours, and the swollen material then heated in said organic solvent to 50-130 DEG  C. until the waste material is completely dissolved.  In the drying step, heating is preferably continued until the waste material has a water content not exceeding 5% by weight.  Preferably, the dried material is added to the organic solvent, e.g. dimethylformamide, while the latter is being agitated and is at a temperature of 5-20 DEG  C., agitation then being continued until dissolution of the waste material has been achieved.  The solution obtained may then be filtered and deaerated before being spun into fibres in a bath of the said organic solvent diluted with water.

Filed: 1935-02-13
Abstract: 456,718. Soot blowers. SIMPSON, J. W. L., Sherwood, Mostyn Avenue, Littleover, Derby. Feb. 13, 1935, Nos. 4676 and 30907. [Class 99 (ii)] In a soot blower of the kind in which a nozzle 1 is mounted on the end of an axially-movable blower tube 2, the supply of cleaning fluid to the nozzle is controlled by a valve 11 which is normally located between seating members 13, 14 in the supply conduit 9 and at the inner end of the blower tube respectively. The arrangement is such that, upon projection of the nozzle into its operative position, the valve will be maintained on its seating 14 by the pressure of the cleaning fluid until the head 12<a> of the valve rod 12 abuts against a collar in the seating 13, when the seating 14 will move away from the valve and permit passage of cleaning fluid; also when the nozzle is retracted the seating 14 will first abut against and close the valve and then return the valve to its original position. As shown, axial movement of the blower tube is effected by a hand wheel &c. through a worm 8 and worm wheel 5, the latter being in engagement with a screwthreaded sleeve 6 freely mounted on the blower tube extension 2<c> and provided with longitudinal keyways 2b engaging fixed keys 7<a> in the blower housing 7 ; the blower tube may also be caused to rotate by providing it with a helical channel 18 for engagement by a pin 17 on the front end 7b of the said housing 7. In a modification the combined axial and rotational movement of the blower is effected by keying the worm wheel 5 to the extension 2<c> and providing the tube 2 with a screw thread for engagement with a thread formed in the front end of the housing 7. The blower tube is cooled by a cooling medium which is circulated through the housing 7 from a port 21 to outlet passages 21<a>.

Title: A device for catching the yarn running off the supply package when the yarn has broken in multiple twist spindles
IPC: D01H13/18
Filed: 1964-02-04
Abstract: 1,047,645. Yarn-catchers; stop motions. VOLKMANN & CO. Feb. 4, 1964 [Feb. 4, 1963; Sept. 16, 1963), No. 4689/64. Heading D1D. A multi-twist (e.g. a 2:1 twister) apparatus has a yarn catcher, which, when the yarn breaks, moves to trap the yarn running into the end of the spindle-tube and prevent more yarn being drawn off the package. Yarn 2 Fig. 2, (not shown), drawn off a package passes through a spindle-tube 3 and forms a balloon between the bottom of the tube and an eyelet 5. A comb 6 is fixed to an inclined shaft 19 also carrying a feeler 21. When the yarn breaks, the feeler arm is no longer held, and due to the inclination of the shaft 19 swings away from the yarn, rotating shaft 19 and causing the comb to trap the yarn near the spindle tube 3. At the moment the yarn breaks, the balloon collapses, and the guide 5 which is supported by the balloon and is pivoted at 22, falls to position 21<SP>1</SP>. To restore the parts, the feeler arm is moved back to a preparatory position where the guide arm 21 rides over an inclined face 27 of the feeler arm and falls into a gap 28. The feeler and catcher arms are thus held outside the range of the yarn. The yarn is pieced, rethreaded through the spindle-tube and the apparatus restarted, whereupon the yarn is tensioned and moves the yarn guide into full-line position and releases the feeler and catcher arms to resume their normal positions. In Fig. 4, (not shown), the parts assume the positions shown in full lines when the yarn breaks, 35 being the catcher and 36 the feeler both carried on a pivoted arm 32. To reset the parts, the arm is moved to be held on a preparatory position 32<SP>1</SP>, a pivoted link 39 moving in a track 42 inside a fixed wire loop and being deflected by an abutment 43 into a holding recess 50. When the apparatus is restarted, the tensioning of the yarn moves the arm to 32<SP>11</SP>, the link moving out of the recess into position 51. When the yarn breaks, the link passes a one-way catch 47 into the full-line position. When the apparatus is at rest with the thread intact the tension is enough to maintain the arm 32 when the catcher is still some distance from the spindle-tube 48. In another form, the catcher arm is slidable in an inclined guide and is normally retained by a catch operated electromagnetically when the yarn breaks. The deflection of the feeler may also be used to actuate a stop motion or initiate doffing of the winding-on spool.
