Title: Improvements in coiling metal ribbon
IPC: B21D11/06
Filed: 1930-09-05
Abstract: 350,337. Coiling. GRISCOMRUSSELL CO., 285, Madison Avenue, New York, U.S.A.- (Assignees of Dewald, E. A. ; Massillon, Ohio, U.S.A.) Sept. 5, 1930, No. 26623. Convention date, Oct. 29, 1929. [Class 83 (iv).] Dies.-A machine for coiling metal ribbon on edge has means for gripping that edge of the ribbon that is to be on the inside of the coil and carrying it about a core while guiding the other portions to prevent buckling. The ribbon 27 is fed from a drum 28 through a guide 30 to a rotating former 24 having a slightly conical face 101, Fig. 12, and a cylindrical face, 101<1>, to. determine the inside diameter of the coil, both faces being of hardened and ground steel. A lower former 25, rotated at the same speed as 24 by gearing 47, 42, 41, 43, 44, 38, Fig. 1, from the main shaft 32, consists of segments 108, Fig. 12, which, for most of each revolution, engage the face 101<1> but are withdrawn between C, D, Fig. 10, by a fixed cam 112. The axis of the former 25 is set by means of studs at an angle to that of the former 24 so that its face, on the line a, b, is parallel with the face 101 and separated by the thickness of the ribbon. With this arrangement the ribbon is first gripped between the formers 24, 25 at d, Fig. 15, and the width gripped increases, as indicated by the line 123 and similarly decreases until the segments 108 are withdrawn. If the coil tends to stick to the face 101 it is separated by a fixed blade, not shown. The coil passes through the former 25 on to a detachable support 31, Fig. 1, which is rotated at a speed slightly less than the formers by adjustable friction gearing 59, 57, Fig. 2, and chain gearing 54 from the main shaft 32. This is driven by a motor 34 through gearing 35 when a clutch 36 is closed by a lever 61, spring-pressed link 64, and spring-returned handle 66. Return of the lever 61 is prevented by a spring pin 71, Fig. 5, until this is retracted by its hook 76 engaging a projection 75 on a chain 74 which is moved in the direction of the arrow by a ratchet on the shaft 79 and a pawl eccentrically mounted on a shaft 85 driven from shaft 32. When this occurs the clutch is opened and the machine stops. The operator then cuts off the coil made and removes it, raises the pawl, and turns the ratchet in the reverse direction until the projection 75 engages a stop 94 which has been.previously set in such position of the groove 96, Fig. 2, that this travel of the projection 75 corresponds to the desired length of coil. The machine can then be restarted and the operation repeated. If desired the former 24 may be adjusted to produce a cross section tapered in either direction or, by being spaced wider than the original ribbon, a cross section which has parallel sides except at the outside edge which is tapered.

Title: Improvements in the system for measuring the capacities of electric conductors
IPC: H04B3/46
Filed: 1920-09-17
Abstract: 172,437. Urmston, J., James, R. N., and Callender's Cable & Construction Co., Ltd. Sept. 17, 1920. Capacities, measuring.-Thermionic valves are used in an arrangement for testing the capacity or difference of capacities between the wires of a telephone cable. The invention is particularly applicable to the arrangement for testing the capacity differences between the various combinations of the four wires of a telephone phantom circuit, in which the wires A - - D are connected to the corners of a double capacity bridge comprising fixed condensers W, Z, variable condensers X, Y and equal non-inductive resistances R<1>, R<2> connected together as shown. In this arrangement the point G between the condensers W, X is earthed and the point H between the condensers Y, Z is insulated. In carrying out the tests, the potentials of the points H, G and that of the point K between the resistances R<1>, R<2> are balanced by adjusting the variable condensers X, Y. In order that the balance may be readily obtained, the points G, H are connected to the grids M<2>, M<1> of a pair of thermionic valves, the point K being connected to the filaments L', L<2>. Telephone head-pieces T<1>, T<2> are included in the plate circuits P<1>, P<2> of the valves, so that the two sides of the bridge can be adjusted simultaneously by a pair of operators. A leak resistance may be provided between the grid and filament of one or both valves, if necessary.

Title: Improvements in percussion fuses for projectiles, bombs and the like
IPC: F42C1/02
Filed: 1934-09-17
Abstract: 429,724. Projectile fuzes. REMONDY, L. E., 42, Rue d'Anjou, Paris. Sept. 17, 1934, No. 26701. Convention date, Oct. 9, 1933. [Class 9 (i)] The direct impact striker of a percussion fuze comprises a front part c<2>, Fig. 1, and a rear part c<1> normally rigidly connected together, for example by being made in one piece or by being fastened together by a transverse shearing pin, and adapted to operate as follows : On impact, the striker is released from the fuze body a, for example by shearing a pin d, and is driven in, then the front part c<2> is arrested by a shoulder a<1> of the fuze body and the inertia of the rear part c<1> causes it to break away from the front part and to fire the fixed percussion cap b. In a modification, Fig. 6, the inertia of the rear part c<1> causes it to break its attachment g to the front part c<2> at the same time as the main pin d is broken. In another modification, a separate inertia plunger is provided to cause the break between the front and rear parts. The striker c<1>, c<2> may be attached to a cap m, Fig. 11, held on the fuze body a by a stud m<1> in engagement with a groove a<3>, the cap m being locked in known manner by a collar n adapted to be withdrawn when a bomb fitted with the fuze is dropped. A centrifugal safety bolt o, Fig. 12, may be provided for the striker ; and an extension p may be formed on the head of the striker to be crushed by a strong target after the main pin d has been sheared, to ensure the above mentioned operation. This operation involves a delay of the explosion of the bomb, and the percussion cap may be situated at a comparatively long distance from the striker and may act directly as the detonator of the main charge of the bomb. In the form shown in Fig. 4, the percussion cap b is held forward by a resilient cushion h of felt or cork or by a spring and can thus set back during acceleration to a safe place where it cannot be reached by the striker. In still another modification, the percussion cap is carried by the rear part of the striker and the firing-pin is fixed to the fuze body in place of the percussion cap. Specification 263,098, [Class 9 (i)], is referred to for a somewhat similar fuze.

Patent GB-510511-A (GB)
Title: Improvements in the manufacture of textile fibres composed of cellulose ethers
IPC: D04H1/425
Filed: 1937-11-02
Abstract: 510,511. Cellulose ethers ; treating textiles with liquids. WALLACH, R. Nov. 2, 1937, No. 26738. [Classes 2 (ii) and 15 (ii)] A mass of loose cellulosic fibres of textilemaking length is treated with an etherifying agent in presence of alkali, shredding of the ' fibres before or during the reaction being avoided, and the reaction is continued until the cellulose of the fibres is converted throughout each fibre to a cellulose ether. The reaction is discontinued when the cellulose ether is soluble in alkali, but insoluble in water. The temperature of the reaction is maintained higher than that at which the alkali present would gelatinize the cellulose ether fibres. Cellulose ether fibres of textile-making length capable of being separated by carding, combing, or the like, are obtained. These may be twisted, spun, or otherwise formed into yarns, threads, fabrics, or cords. The cellulosic fibres may be etherified while in a swollen state, and the product may be purified, washed, and dried without exerting any substantial pressure thereon in the fibrous mass. Natural or artificial cellulosic filaments or fibres such as rayon fibres, or staple fibres of cotton, hemp, jute, flax, or straw, may be subjected to the treatment. Waste cellulose hydrate filaments cut to staple length may be used. The fibres may be treated with a dilute solution of a strong alkali until they are thoroughly impregnated and swollen, but not gelatinized, and then after centrifuging and pressing, they are treated.with an etherifying agent. Caustic soda or potash, dimethylamine, or a quaternary base, e.g., tetra-benzyl ammonium hydroxide, may be used as the alkali. During etherification, when starting from cellulose hydrate fibres, the ratio by weight of dry cellulose to solid alkali calculated as NaOH should preferably not exceed 1 : 0.2. The etherifying agent may be ethyl chloride, diethyl sulphate, ethylene chlorohydrin, epichlorohydrin, ethylene oxide, propylene oxide, or a glycide. When using ethylene oxide the proportion is preferably not less than 0.3 mols per mol of cellulose. Etherification may be carried out in a closed vessel at room temperature or at slightly raised temperature, e.g., 25C. Cellulose ether fibres which are completely soluble in 9 per cent. aqueous caustic soda at 0C. are obtained. Instead of carrying out the treatment with cellulose fibres alone, these may be mixed with inert fibres, e.g., asbestos, glass, rubber, or synthetic resin fibres prior to the treatment. The cellulose ether fibres may be used in the production of textile fabrics, unwoven structures, cords, ropes, and motor tyre cords. They may be used in the production of articles which are to be stiffened and such treatment may consist in the application of a dilute alkali so as partly to gelatinize the fibres in the textile structure, and then in the removal of the solvent.

[Also in Division G3] An induction motor has silicon controlled rectifiers 3-3b replacing the star-point of primary or secondary windings 1-1b, the speed of the motor being controlled by adjusting the firing-angle of the rectifiers. One of the rectifiers is fired separately to provide directcurrent braking. For power operation of the motor, the outputs of saw-tooth generators 5-5b are superimposed upon a reference voltage from source 7 which is opposed by the output of tachometer generator 10. The resultant voltages are applied to phase-control circuits 9-9b providing the gating signals for the rectifiers. During motoring operation, the gating signals are retarded if the motor speed increases. A further saw-tooth generator 15 and phase-control circuit 18 are associated with the rectifier 3 for stable speed operation when the motor is over-driven by the load. The tachometer generator may be replaced by a device responsive to the torque or output power of the motor.
