Title: Bulked yarn
IPC: D02G1/02
Filed: 1955-06-07
Abstract: 805,757. Crimping yarns. CELANESE CORPORATION OF AMERICA. June 7, 1955 [June 8, 1954], No. 16310/55. Class 120(3) Artificial multifilament yarn of an organic ester of cellulose of a degree of substitution above 2.5 and particularly cellulose acetate of acetyl value at least 60 per cent (reckoned as acetic acid) is bulked by crimping the filaments thereof and setting to increase the crystallinity of the cellulose ester. Thus the yarn may be twisted to an extent coresponding to a twist multiplier of 500-1000, set as by heating to a temperature of 150-250‹C. for a period of 0.5-5 seconds by means of hot gas, radiant heat, contact with a hot plate or roll, wet steam, or hot water or combinations of such media, then untwisted to a lesser, similar, or greater extent than the first twisting. The bulking process may be effected continuously by false-twisting combined with setting or by stages e.g. by twisting, winding on to a package which is treated to increase the crystallinity of the ester, then running the yarn from the package and untwisting it. The crystallinity may be increased to the maximum at a first setting treatment or in stages, e.g. completed after the crimped yarn has been wound into a package under low tension and/or knitted 'into fabric. A swelling agent or plasticizer, e.g. diethyl phthalate, dibutyl phthalate, tributyl phosphate, tripropyl phosphate, trioctyl phosphate, for the yarn material may be incorporated during spinning or applied before or during the bulking treatment, to allow the yarn to be heated at a lower temperature or for a shorter time, and may be subsequently removed, as by washing the yarn with a selective solvent. The yarn may be doubled with other bulked, unbulked, and/or shrinkable yarns. Specifications 424,880, 442,073, [719,853, 719,860, 721,674, 726,900, 748,772, 753,461, 758,442, 761,158, 763,489 [all in Group IV(a)]], 764.869 and 776,346 [Group IV(a)] are referred to.

Abstract: 582,622. Toothed gearing. BAUMANN, K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 18, 1942, No. 16343. [Class 80 (i)] [Also in Group XXVI] The rotors of a contra-rotational turbine are connected together and to a power shaft by epicyclic gearing arranged so that, when the turbine is idling, the power shaft turns both rotors in the same direction. A simple gear is shown in Fig. 1 and other forms are described. The rotor shafts B, C carry external and internal gear teeth b, c engaged by the same pinion e1, mounted on an arm a fast on the power shaft A. The spindle E of the pinion e carries also a pinion e2 which engages teeth on a wheel F. The wheel F is mounted freely on the shaft A and is integral with a brake drum F1. When the drum F., is held by the brake band F2, the turbine rotors rotate oppositely and transmit power to the shaft A. When the turbine is to idle, the drum F, is freed and, as the shaft A rotates under other power, the turbine rotors are carried round in the same direction. A positive stop may be provided in addition to the brake band.

Filed: 1926-06-29
Abstract: 278,074. Armstrong, Whitworth, & Co., Ltd., Sir W. G., Lee, H. W., and Morrison, R. June 29, 1926. Sights.-Relates to driving-gearing, particularly applicable for operating gun-director telescopes B, indicators D, and transmission shafts E for forwarding the motion to the gun, and consists in taking up backlash in the gearing, for example between worm-wheels 1 and 2 directly actuating the telescope B, by an initial axial movement of the driving-worm 3, such initial movement not affecting the parts D, E. The worm is secured to a shaft 4 which is tapped to engage a screw 5 secured on the main operating shaft 6 and carries a splined sleeve 13 formed with a lug 15 normally spaced from a lug 16 of a sleeve 18 secured to the shaft 6. The shaft 4 is also splined to a shaft 8 carrying a worm 10 driving the indicator D. The sleeve 13 is formed with a bevel wheel 12 driving a wheel 14 on the shaft E. The first movement in either direction of the hand-wheel driving the shaft 6 produces, by the action of the screw 5, axial movement of the shaft 4 and worm 3, this movement, which is designed to be sufficient to take up the backlash in the gearing between the wheels 1, 2, continuing until the lug 16 strikes the lug 15, when rotation of the worm 3 commences. The pitch of the thread or the play between the lugs 15, 16 is varied according to the extent of the backlash to be taken up, for which purpose one or both of the lugs may be adjustable.

Abstract: 276,308. Bonnefont, A. Aug. 17, 1926, [Convention date]. Addition to 269,211. Wireless tuning- apparatus, adjustment devices for.-A coarse and fine adjustment device disposed within the axis of the apparatus to be controlled, as claimed in the parent Specification, comprises a shaft secured to the operating-knob a and provided with a screwthreaded part band a second screw-threaded portion b<1> having a somewhat smaller pitch. The part b<1> screws into a ring h which, according to the present invention, is tapered externally to engage a similarly tapered seating on a stationary frame i with hard friction. The ring h has an arm h<1> projecting into the path of a stud b<2> on the shaft. The threaded part b screws into the tapped upper part of a rod c<1>, the lower end of which is formed with a quick-acting screwthread c<2>, by which rotation is imparted to the rod c<1> when this rises or descends. This rotation is transmitted to the movable plates f of the condenser by a stud c<3> sliding in a slot c<4> in a socket e carrying the plates f. A volute spring g serves as a conductor and prevents backlash. Rotation of the knob a causes the rod c<1> to be moved axially by an amount corresponding to the difference of the pitches of the screw-threads b, b<1> until the stud b<2> contacts with the arm h<1>, whereupon the ring h is rotated and the screwthread b only is operative, giving a quick motion. Reversal of the direction of rotation of the knob a brings the differential screws into action, giving a fine adjustment.
