Patent GB-832546-A (GB)
Title: Continuous flexible wire or stock winding apparatus
IPC: B65H67/056
Filed: 1957-03-28
Abstract: 832,546. Wire &c. winding apparatus. STANDARD MACHINERY CO. March 28, 1957 [April 3, 1956], No. 10243/57. Class 120(2) [Also in Group XXVIII] In the wire &c. winding apparatus of Specification 824,695 each reel carries a wire or stock anchor of generally circular form having a peripheral rim on which one or more turns may be wound, and peripheral guard means for preventing the wire or stock from flying outwardly, the guard means being so constructed as to allow ready removal of the cut off ends when the wound reel is in the reel exchange position. As shown the anchor 48 is removably mounted on the reel spindle 74 and is coupled with the reel R through pin 250. It has a hub 242 connected by a plurality of radial spokes 244 to an annular border 246 which continues as a frusto-conical stock deflector flange 248. Secured to the border 246 are equi-angularly spaced brackets 256 provided with ledges 258 which together form a stock winding-on rim 260. Outwardly spaced from the ledges 258 on the brackets 256 are lugs or detents 262 which serve to block any appreciable outward expansion, and hence unwinding of stock turns on rim 260. The detents 262 are preferably inclined inwardly toward the deflector flange 248 so that their outer surfaces 264 will serve to deflect stock on to the flange 248 and then into winding relation with the rim 260. The arrangement is such that when one reel is fully wound and the stock quickly transferred to the empty. reel, the wire is first caught and a few turns wound on the anchor of the full reel and then on the anchor of the empty reel, prior to winding thereon. The length of stock between thetwo reels is then severed. Alternatively to the above the wind-on rim may be continuous and cylindrical or it may be shaped to produce a .wedging action on the stock so as to prevent it flying outwardly. Also the anchor unit may be permanently or releasably attached to the reel.

Title: Improvements in or relating to a process and device for the manufacture of permanently crimped or waved yarn from fully synthetic organic textile fibres
IPC: D02G1/02
Filed: 1954-04-12
Abstract: 746,992. Crimping yarns. HEBERLEIN & CO., AKT.-GES. April 12, 1954 [April 16, 1953], No. 10678/54. Drawings to Specification. Class 120 (3). Yarn consisting of synthetic organic textile fibres, e.g. of polyvinyl compositions such as polyacrylonitrile, polyamide, or polyester fibres, and possessing normal or zero twist, is crimped or curled by imparting to such yarn (or to a number of yarns simultaneously) a temporary high twist in a false-twisting device, subjecting this twisted yarn to a wet and/or hot treatment, and withdrawing the yarn from the twister at a rate at least 0.5 per cent greater than the rate of feed thereto in order to stretch the yarn by a corresponding degree in its passage through the twister; the product may then be steamed to intensify the crimp. Optimum results are obtained by imparting a stretch of 4-10 per cent and a preferred limit is 20 per cent. The high twist may be applied beyond the zero-twist point in a direction opposite to that of an initial twist in the yarn. Two yarns that have been highly twisted in opposite direc - tions may be doubled to form a yarn having normal twist. The invention may employ false-twisting devices described in Specifications 606,257 and 611,538 and the processes described in Specifications 744,735 and 744,736.

Abstract: 650,534. Frictional igniters. WARD, A. F. April 29, 1947, No. 11429. Convention date, May 17, 1946. [Class 75(iii)] A frictional lighter comprises an elongated body 6 having a transverse chimney 8 extending therethrough preferably near one end of the body, and having an unobstructed opening at each end, a cover 7 being slidable over the body to open and close the ends of the chimney. A fuel compartment 9, in the other end of the body, communicates with the chimney 8 through a longitudinal wick passage 10 which is cut near the centre of the body. The body 6 also carries the usual flint tube 12 extendthrough a side of the chimney and a friction wheel 13 mounted in a slot which opens into the chimney and lies transverse to the axis thereof. To facilitate moving the cover and to increase the height of the chimney when the lighter is in its inoperative position, the inner end of the cover has a thickened portion 19 provided with diametrically opposed openings 20 which coincide with the chimney 8 when the cover is moved outwards to give access to the wick. Outward movement of the cover is limited by the engagement of a spring-loaded detent 16, housed in the body 6, with a hole 17 in the cover 7, the cover being yieldingly retained in its closed position by the engagement of the detent with another hole 18 of smaller diameter.
