IPC: D06M15/423
Filed: 1969-01-14
Abstract: 1,243,462. Curing cross-linking agents on textiles. COTTON SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. 13 Jan., 1970 [14 Jan., 1969], No. 2249/69. Heading D1P. A crossing-linking agent is catalytically cured on textile material consisting wholly or partially of cellulosic fibres by impregnating the material with a cross-linking agent which is formaldehyde or a chemical having at least two separate N-methylol groups or ether or ester derivatives thereof, each group being capable of reacting with a cellulosic hydroxyl group and simultaneously or subsequently subjecting the material to the influence of the vapour of a liquid with a boiling point in the range 40‹-<100‹C at atmospheric pressure and being capable of forming an azeotrope with water. The liquids with boiling-points between 40‹-<100‹C used may be benzene and halo hydrocarbons such as trichloroethylene, methyl chloroform, methylene chloride and 1,1,1 trichloroethane. The textile material may be in the form of fibres, rovings yarns or woven or non-woven fabrics. Examples of cellulosic materials which may be treated are cotton, linen, paper, viscose rayon and high wet modulus rayon. The cellulosic fibres may be blended, for example with polyamide, polyester, polyacrylic or wool fibres. The textile material is either impregnated with the cross-linking agent prior to its subjection to the action of the vapour, or the cross linking agent is volatile and is incorporated in the liquid. Catalysis of the crosslinking reaction may be achieved by:- (a) incorporating a catalyst in the textile material, e.g. magnesium chloride, zinc nitrate; (b) incorporating a volatile catalyst within the liquid, e.g. hydrogen chloride in benzene or incorporating in the liquid a compound or compounds capable of liberating such a catalyst, e.g. acetyl chloride, or (c) utilizing as the liquid one which decomposes so as to liberate a volatile catalyst e.g. trichloroethylene, or which contains as a normal impurity such a catalyst.

Abstract: 1,122,853. Welding by pressure. D. SCIAKY. 18 Jan., 1966, No. 2262/66. Heading B3R. In resistance welding sheets by means of electrodes on opposite sides thereof the sheets are restrained from separating by applying pressure over an annular area around the tip of each electrode and the tips are cooled by circulating cooling fluid about the outer surfaces thereof. An electrode shank 1 has a threaded section 2 on a reduced diameter section 4 carrying a tip 3 and around the section 4 is an annular body 5 to which hydraulic fluid is admitted by a port 7 to exert pressure between a flange 9 on the electrode and a wall 10 on the body 5 to move the body downwardly and press a ring 26 screwed to the end of the body 5 on to the work around the tip 3. Cooling water is passed through the electrode shank to cool the inside of the tip and water is passed through a port 15 to flow over the outside of the tip and within the ring 26. A seal ring 32 prevents leakage on to the work beyond the ring 26. In a modification a spring is employed instead of the hydraulic pressure. Insulating rings 28, 29 prevent passage of current to the ring 26. A pair of identical electrodes are provided on the arms of the machine. The welding of titanium is referred to.

Title: Improvements in or relating to means for reducing the induced voltage when an inductive circuit is interrupted
IPC: H01H9/54
Filed: 1941-03-03
Abstract: 548,345. Protective arrangements. IGRANIC ELECTRIC CO., Ltd., and RANDALL, C. E. March 3, 1941, No. 2858. Drawings to Specification. [Class 38 (iv) [Also in Group XXXVII] Means for reducing the induced voltage when an inductive circuit is broken comprises a path whose impedance decreases with rise in voltage, in parallel with a capacity, and connected across the inductive device in the circuit. Normally little, if any, current flows through the path whereas, when the circuit is opened, the induced voltage produces a fall in the impedance of, and hence an appreciable current in, the path. The arrangement thus reduces arcing at the contacts of the controlling switch, and quicker response of the induction device when energized and de-energized, is obtained. Preferably there is employed, however, a solid non-linear resistance material such as " Metrosil " (Registered Trade Mark), arranged in suitable form on clips on a base plate to which the parallel condenser is secured; Figs. 1 and 2 (not shown). The Provisional Specification states also that the shunting device may comprise a discharger driver the breakdown voltage of which is above that normally impressed on the inductor device, for example, a mercury cathode, or heated cathode, or gas discharge device.

Abstract: 565,148. Converting. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Feb. 24, 1943, No. 3024. [Class 38 (ii)] In an arrangement for transmitting power between an A.C. circuit 1 and a D.C. circuit 2, 3 through a pair of valves 5, 6 of the immersionignition type, the valves are provided with auxiliary anodes 10 to which voltage impulses of adjustable phase and extended duration are applied to maintain ionization for a substantial portion of each conducting half-cycle after the arc has been transferred from the ignition electrodes 9 to the auxiliary anodes 10. Ignition impulses of short duration are applied to the ignition electrodes 9 from an impulse generating circuit 11 which is energized through a phase shifting network including a variably saturated inductance 16, whereby regulation of the converter is effected. The voltage impulses appearing at the terminals 22, 23 of the impulse generating circuit are also applied to the auxiliary anodes 10, but have superposed thereon voltage impulses of extended duration provided by a transformer 27 fed through a phase shifter connected to the A.C. circuit 1. Fig. 3 shows a modification in which two arrangements similar to that of Fig. 1 are energized in quarter-phase from transformers 33, 34, Scott-connected to a three-phase supply 30. According to the Specification as open to inspection under Sect. 91, unbalance between the two halves of the system is prevented by differential control of the saturating circuits of ignition-regulating inductances 16 effected by applying across a resistance 50 the difference between two rectified voltages produced by current transformers 53, 54 associated with the anode circuits of the two halves of the system. The Specification as open to inspection under Sect. 91 also includes a modification, Fig. 4 (cancelled) (not shown), in which the voltage impulses of extended duration are applied across the output winding of the impulse generating circuit. These subject-matters do not appear in the Specification as accepted.
