Title: Improvements in preventing the electrostatic charging of fibres, threads or productstherefrom
IPC: D06M15/356
Filed: 1956-10-12
Abstract: Fibres or threads or products therefrom are treated with a solution of a highly polymeric organic cation-active compound and with a separate solution of a highly polymeric organic anion-active compound.  The compounds may be applied in either order.  One of the compounds may be included in a lubricant or size.  The cation-active compound may be poly-N-vinylimidazole, polyvinyl pyridine, a polymerized aminostyrene or a polyacrylic acid chloralkyl ester which has been reacted with triethylamine. The anion-active compound may be a polystyrene sulphonic acid, polyacrylic acid or polymethacrylic acid or salts thereof or a copolymer of styrene and maleic acid.  In the example, an aqueous solution of poly-N-vinylimidazole quaternized with dimethyl sulphate is applied to polycaprolactam fibres at 30 DEG to 95 DEG  C. and, after squeezing or hydroextracting, the fibres are treated with an aqueous solution of a styrene-maleic acid copolymer also at 30 DEG  to 95 DEG  C.  The fibres are finally dried at 70 DEG to 100 DEG  C. Yarns or woven or knitted fabrics of silk, wool, cotton, acetyl cellulose, polyamides, polyurethanes, polyvinyl chloride, polyacrylonitrile, or terephthalic acid-glycol polyesters may be treated.

Title: Improvements in variable-speed gearing
IPC: F16H3/66
Filed: 1933-11-13
Abstract: 428,779. Variable-speed and reversing gearing. EVANS, 0., 27, Chancery Lane, London.-(Demag Akt.-Ges. ; 64, Werthauserstrasse, Duisburg, Germany) Nov. 13, 1933, No. 31637. [Class 80 (ii)] Variable - speed gearing, for a vehicle or a winch, comprises a series arrangement of twospeed epicyclic or countershaft gears, controlled in stages by groups of friction clutch discs, so arranged that a clutch disc to be put into engagement presses upon and disengages a disc to be disengaged, without the occurrence of any " free " position of the gear during the change. Similarly-controlled reversing-gearing is also provided. The epicyclic gears 18, 18<a>, 18<b>, 18<c>, Fig. 1, are changed from reduced to solid drive when clutch-cones 19 secured to their annuli 17, are pushed out of clutching engagement with an inner rotating casing 21, by advancement of solid - driving clutch cones 22, such advancement being produced in succession by continued movement, in either direction of a hand - lever 9. The clutchcones 22 are secured to slidable shafts, each carrying the sun - wheel of one stage and the planet-carrier of the preceding stage, the shaft in the case of the first stage being the driving shaft 5. The inner casing 21 is permanently driven from the final driven shaft 23 by a constant-mesh countershaft train 26. The driving shaft 5 is driven by a double clutch-cone 4 adapted to be pushed off a fixed brake-ring 7, against a spring 12, by advance. ment of either of two oppositely-rotating clutch - cones 3, 33, the latter being driven through bevel reversing wheels 30, 31, 32 by a motor A, which directly drives the cone 3. Forward movement of the controllever 9 acts through a lever 11 on the forward clutch cone 3, continued movement successively locking the epicyclic trains 18. Rearward movement acts through a lever 34 on the reverse cone 33, continued movement operating the gear stages, as before. In Fig. 2, each gearstage is changed from a reduced drive through a countershaft 80, to a directdrive, when a clutch cone 79, secured to the driven shaft of a preceding stage, engages a cone 82, secured to the driving shaft of the following stage, such engagement pushing the cone 82 away from a clutch-ring 81, 81, secured to the driven wheel of the preceding stage. The gear is driven through a reversing- gear as in Fig. 1, with the exception that the hand-lever 70 acts on the clutch-levers 74, 76 through cams 71, 72, and a spring 70<a> assists the movement of the lever in either direction. In order to prevent top-speed being engaged under heavy load, the latter is caused to react back on the control lever by taking off the drive through a helically-toothed wheel 86. Each clutch-unit E, F, or G, together with a gear wheel on either side of it, may be withdrawn from the gear casing, for inspection, by a lateral movement, loose couplings 84 being provided for this purpose.

Filed: 1922-11-21
Abstract: 206,374. Fairweather, W., (Singer Manufacturing Co.). Nov. 21, 1922. Sewing - machines; starting and stopping gear.-In stop mechanism for machines for sewing on buttons, barring, tacking &c. a positive stop is associated with a brake. which is applied at the inception of the stopping action and released at its completion. The apparatus is described as applied to a machine of known type for attaching buttons and compris. ing a stop-lever 16 carrying a belt-shifter 18 and a, spring plunger (not shown in Fig. 3) which engages a positive stopping-cam 20 on the main shaft, this lever being also mounted so as to have a limited sidewise or shock-absorbing movement after engaging the cam. The lever 16 is held out of operative position by a catch 22 released at the close of a stitching operation by a lug 23 on the cam-wheel 12. At starting the lever 16 is moved out of alignment with the cam 20 and into re-engagement with the catch by the manual operation of a bell-crank lever 27, 28 connected to a spring-pressed rod 26. The brake 32 is mounted on a spring-controlled lever 33. A lever 39 is mounted so that one end may be engaged by the lever 16 in its sidewise motion, the other end engaging a stud on a sliding bar 41, a cam-lug 42 on which engages a cam-lug 43 on the brake lever 33. The bar 41 has a projection 44 engageable by a spring pressed latchlever 45 carrying a trip 48 held yieldingly at right-angles to, the lever 45 by a spring 49. On starting the machine by moving the lever 16, the brake being then inoperative, the slide 41 is latched in its right hand position in Fig. 5 and the trip 48 is in position to be moved by the initial stopping movement of the lever 16 to release the lever 45 from the bar 41 and free the brake from detention by the lug 42. The catch 22 being tripped to release the lever 16 and the) brake lever 33, the stopping cam comes into contact with the lever 16 and moves it sidewise against the action of a plunger b. This motion of the lever 16 acting through the lever 39 effects the resetting of the slide 41 and puts the brake out of action the catch 45 being allowed to engage the stop 44 owing to release of the trip 48 from the lever 16. The sidewise movement of the lever also effects the final thread-cutting movement of a thread-cutter by its action on a bell-crank lever 57, 59, engaging a stud 56 on an operating-slide 50.

Abstract: 655,238. Screwing-up screws and nuts. LINES BROS., Ltd., and LINES, W. Dec. 10, 1948, No. 32039. [Class 83 (iii)] [Also in Group XXIV] In a method of assembling a wire-spoke wheel in which the spokes are placed loosely in position between the hub and rim which are gripped in a jig, the slack in the spokes is taken up by applying a small torque to either the outer ends of the spokes or nuts threaded on those ends and thereafter the spokes are tightened to substantially the same tension by simultaneously applying a larger torque to the spokes or nuts. Apparatus for carrying out the method comprises jig parts 24, 26, Fig. 10, a screwdriver 35 or the equivalent corresponding to each spoke 4, and a compressed air system controlled by a valve 130, 132 which in a single cycle of operations brings about the movement of the part 26 towards the part 24 to close the jig, the approach of the screwdrivers to slotted nipples 10 at the outer ends of the spokes, the simultaneous turning of all the screwdrivers with a small torque to take up slack, the simultaneous turning of all the screwdrivers with a larger torque to tighten the spokes, the withdrawal of the screwdrivers, and the opening of the jig. The, screwdrivers are reciprocated into and out of engagement with the nipples by means of pistons 60 movable within cylinders 62 to which compressed air is supplied by means of pipes 64, 65. The screwdrivers are driven by means of compressed air supplied through pipes 72, air being first supplied under low pressure so that only a small torque is applied, after which the screwdrivers stall, and then under higher pressure, the screwdrivers being driven through clutch elements 82, 84, Fig. 8, which are designed to slip when the final tension has been set up. The screwdrivers are guided on to the nipples by means of a pin 92, or sleeve, which is spring- urged to project beyond the tip of the screwdriver blade 76. The lower jig part 24 is provided with slots 44, Fig. 4, for locating the spokes. The valve rod 130 is operated by means of a handle 98, Fig. 11, working in a gate 100 and integral with a quadrant 118. Instead of using compressed air, the apparatus may be operated electrically or mechanically.
