Title: Improvements relating to the treatment of woollen or worsted fabrics
IPC: D06C21/00
Filed: 1940-07-08
Abstract: 542,446. Treating textile fabrics. WRIGLEY, J. H., MELVILLE, A., and KELLETT, S. July 8, 1940, No. 11403. Drawings to Specification. [Class 15 (i)] [Also in Group VIII] Woollen or worsted fabric is first shrunk in length mechanically at least to the extent at which it will become longer if moistened while unconstrained, and thereafter while constrained to maintain the mechanical shrinkage is set by a plasticizing treatment involving side chain breakdown followed by linkage rebuilding. The plasticizing treatment is effected by subjecting the fabric to the action of steam, and thereafter cooling it. The mechanical shrinking may be carried out in apparatus as described in Specification 529,579, [Group VIII], and on leaving the shrinking apparatus, the fabric is wound on a roller with a carrier fabric that is under tension to retain the treated fabric in its shrunk form, and the composite roll is subjected to tbe plasticizing and de-plasticizing operations. The roller may be perforated so that when the roll is placed upon a carriage within a steam chamber, the steam passes through the composite fabric and escapes from the inside of the roller. To protect the fabric from condensate, closely woven fabric is placed upon the roller and the complete roll is wrapped in a similar fabric wrapper. After the plasticizing treatment, the fabric may be treated so that it acquires potential relaxation shrinkage and is then treated by the method claimed in Specification 542,169, [Group VIII]. Specification 359,759, [Group VIII], also is referred to.

Filed: 1946-04-17
Abstract: 610,896. Fixing wire brush bristles. CHARLESWORTH, G. W. April 17, 1946, No. 11928. [Class 19] A metal tube a is provided at one end with a handle or hand grip b and near its other end is preferably bent as shown, so that its extremity extends at an angle to the axis of the tube. Within the tube is a bundle of wires d, one end of which is clamped in a tubular holder e, which is slidable within the tube a and handle b. A screw g passing through a threaded hole in the wall of the tube a is adapted to clamp the wires d in the tube. The extremity of the tube is preferably provided, as shown, with a nose-piece c having a flattened or elongated orifice c<SP>2</SP>. The nosepiece is adjustable angularly within the limits of a slot c<SP>1</SP> through which the screw g passes. The latter thus serves both to clamp the wires in the tube and to clamp the nose-piece in the desired angular position. The end of the holder e has a nut e<SP>1</SP> through which works a screw f, the head of which is adapted to bear against the end of the handle b. By positioning the holder by means of the screw f, the ends of the wires are arranged to protrude to the desired extent from the orifice of the nose-piece, the shape of which causes the wires to be flattened out. When the wires are worn down the screw g is slackened, the screw f rotated so as to be withdrawn a short distance from the holder e, which is then pushed forward until the screw head f<SP>1</SP> abuts once more against the end of the handle b, the screw g being finally re-tightened. The bristles may be advanced in this manner as they wear away until the supply is exhausted or the screw g has been fully withdrawn. A length of twisted wire rope may be employed instead of the bundle of wires.

Abstract: 276,049. Muck, O. May 12, 1926. Electric clocks. - In apparatus for operating, or cornecting, electric secondary clocks, audio-frequency currentimpulses are superimposed on the ordinary line current of an existing system (e.g. power - distributing system), the clocks being controlled by resonance relays which respond only to the audio-frequency impulses. The central station Z, Fig. 10, comprises a controller S, a master clock N, and an audio-frequency generator G, through which, at the correct times, audiofrequency impulses are transmitted over the existing system to the resonance relay R<1>, of the secondary clock A. This relay is so tuned that it is unaffected by the ordinary line current but responds, say once a minute, to the audio-frequency impulses to move the clock A on step by step. In clock B the windings W1, W2 are energized alternately and rotate an armature P, the pole pieces of which are alternately north and south magnetic. In clock C for three-phase A.C. systems impulses of two frequencies alternate with each other to energize the windings M2, M3 and move the pawl K forwards and backwards.
