Abstract: 1,176,836. Shrinkproofing wool. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION. 15 March, 1967 [30 March, 1966], No. 12216/67. Heading D1P. Wool fibres are shrinkproofed by subjecting them to the action of an electric discharge and then treating them with a synthetic polymer. The electric discharge treatment may be carried out at or below atmospheric pressure for 10 seconds to 5 minutes using voltages of 10,000-100,000 at frequencies of 50 to 500,000 cycles per second. The treatment may comprise corona discharge or a discharge in a preselected atmosphere where chemically active compounds or radicals are produced close to the wool. The discharge treatment may be applied to loose wool and the polymer applied later by spraying on to the loose wool or impregnating a woven or knitted fabric made therefrom, or the discharge treatment may be applied to woollen fabrics immediately after scouring or dyeing and the polymer then applied as the next step in processing. The polymer which may be applied in the form of an aqueous dispersion in an amount of 0.5-10% by weight of the wool may be a polyethyleneimine, polyamide-epichlorohydrin resin, polyolefin, polyacrylate or melamine-formaldehyde resin.

Abstract: 485,051. Covers for resisting fluid pressure. FRITSCH, E. April 29, 1937, Nos. 12248, 12250, and 12251. Convention dates, May 2, 1936, Feb. 5, 1937, and March 1, 1937. [Class 123 (i)] [Also in Groups XXVI and XXIX] In a steam-pressure cooking vessel, the rim b of the lid a fits with some play within the rim c of the body part. An elastic packing ring f is forced by internal pressure into the space between the rims. The lid is retained by means of lugs g which engage with lugs h when the lid is rotated, but allow some vertical play. Excessive displacement of the ring f by pressure uncovers openings e which allow steam to escape. The ring f may be of rectangular section. To avoid abrasion of the ring f by rotation of the lid, the lugs g or h may be provided on a separate ring which is rotatable but not axially displaceable. The Specification as 'open to inspection under Sect. 91 comprises also a modification, Fig. 8 (Cancelled), in which the pressurerelieving function of the ring f is replaced by a separate rubber ring n which covers openings in a hollow knob l. This subject-matter does not appear in the Specification as accepted.

Abstract: 213,791. Jackson, P. R., (Sperry Gyroscope Co.). May 8, 1923. Gyroscopic apparatus.-A gyroscope device, for use e.g. in bombing operations, for indicating deviation of an aeroplane or other dirigible craft from a predetermined straight course is adapted to be locked in a centralized position in relation to the craft and to be unlocked while the gyroscope is spinning. The gyroscope wheel 45 is mounted on bearings 51 in a ring 50 pivoted on a horizontal axis at right-angles to that of the bearings 51 within a ring 25 pivoted on a vertical axis within the forward portion 10 of a casing fixed to the dashboard of the craft, the rear portion 11 of this casing being provided, with a window 20. The upper and lower bearings of the ring 25 are adjustable for centralizing the wheel ' 45 vertically. The periphery of the wheel 45 is formed with buckets 85 to which air for driving the wheel is delivered through .nozzles 81, 82, Fig. 5, near the end of a tube 77 which receives the air through a screen 75, passages 33, and the hollow trunnions 26 of the lower bearing of the frame 25. The air suction is obtained by the use, as described in Specification 152,008, of a Venturi tube connected by piping to a hand-controlled valve in the casing 10. The jets from the nozzles 81, 82 are arranged to strike the buckets 85 at substantially equal distances above and below the axis of the wheel 45 to eliminate precessional effects when this axis is tilted in relation to the ring 25. An arm 62 fixed to the ring 25 extends towards the window 20 and carries an index 65 co-operating with a scale 66 adjustably supported from the casing 10 to indicate lateral deviations from a straight course. A weight 60 adjustable according to the latitude on a threaded rod 61 secured to the ring 50 serves to counteract precession due to the earth's rotation and co-operates with a cross-wire 99 to indicate deviations in a vertical plane. To lock the gyroscope in a centralized position the end' 91. of an extension of one of the bearings 51 is engaged by a hole 90 in the vertex of a cone 86 forming part of a member 96, and to unlock the gyroscope while spinning the member 96 is retracted against the action of a spring 97, Fig. 3, by pulling on a wire 92.

Abstract: 405,300. Controlling speed-varying mechanism. ARMSTRONG, WHITWORTH, & CO. (ENGINEERS), Ltd., SIR W. G., Thames House, Millbank, London, BECKETT, C. M., 55, Wordsworth Drive, Cheam, Surrey, and WATKINS, D. J., 103, Sunnyhill Road, Streatham, London. May 4, 1932, No. 12854. [Class 69 (ii).] An hydraulic variable-speed gear 10 suitable for vehicles is operated through a fluid servomotor 4 under automatic control through a valve 3 from a speed-responsive device 1 driven by the prime mover. In the arrangement shown, the device 1 is a centrifugal governor and the valve 3 is fast on a shaft 2 which is rocked by the governor and controls the fuel supply to the engine, not shown. Pressure oil from a source such as the transmission device 10 or the lubricating system enters by a pipe 11 and leaves by a pipe 12 or a pipe 13. As the valve 3 is tilted one way or the other by the governor, pressure oil enters on one side or the other of the angularly movable piston of the motor 4 so as to rock a control lever 9 of the hydraulic variable-speed gear 10. Supervisory control may be furnished by solenoid-controlled valves 5, 6 like the valves shown in Fig. 3 of Specification 380,448. When the valves 5, 6 are de-energized corresponding to the lower, dotted, positions shown, the motor 4 returns the hydraulic gear 10 to low gear ready for starting. The valves 5, 6 are energized to start the vehicle from rest. The valve 5 prevents the gear 10 being changed up when the vehicle is at rest with engine running. The valve 6 can be used to prevent the gear 10 being changed up by the governor, while allowing automatic changing down. The speed at which the engine is required to work may be varied by varying the setting of the governor-controlled valve 3 by means described with reference to Figs. 6 to 8 of the Specification referred to. An arrangement is described in which the servomotor piston is actuated by fluid in one direction only against a spring, like the arrangement of Fig. 4 of the same Specification.

Title: Improvements in or relating to the treatment of textile materials
IPC: D06M13/224
Filed: 1932-05-05
Abstract: Yarns, bristles, straws, and like filamentary materials made of or containing an organic derivative of cellulose are conditioned by treatment with an agent comprising an alkyl ester of a hydroxybutyric acid, which may be applied as such or diluted with a non-solvent for the cellulose derivative.  The diluent may be water or a hygroscopic liquid such as ethylene glycol, diethylene glycol, or triethylene glycol, or a glycol ether which is a non-solvent for the cellulose derivative.  The materials may be treated with the conditioning agent in the course of their transmission from the spinning cabinet or while they are otherwise in transit, or they may be immersed in the conditioning agent. The materials may contain cellulose formate, acetate, propionate or butyrate, or methyl, ethyl or benzyl cellulose, with or without other fibres such as natural silk, regenerated cellulose, wool or cotton.  The process may be applied to yarns formed from continuous filaments or to staple yarns.  The treatment increases the flexibility of the materials and improves their stability to storage; it facilitates the knitting of yarns and the knotting, bending or braiding of bristles or straws.  The conditioning agent may be removed from the materials, or from products made therefrom, in the usual scouring and/or dyeing operations.  Examples are given in which cellulose acetate yarn is treated with a mixture of ethyl a -hydroxyisobutyrate, diethylene glycol, and water.  The Specification as open to inspection under Sect. 91 describes a process for conditioning textile materials made wholly or partly of an organic derivative of cellulose by treatment with an agent comprising a solvent or a latent solvent for the cellulose derivative.  As suitable solvents or latent solvents, mention is made of benzyl alcohol, diacetone alcohol, monoacetin, diacetin, triacetin, acetylcarbinol, cyclohexanone, cyclopentanone, ethyl lactate, dimethyl tartrate, and triphenyl phosphate or a mixture thereof with tricresyl phosphate.
