Title: Compressed-gas circuit breaker
IPC: H01H33/16
Filed: 1965-11-18
Abstract: 1,080,580. Gas blast switches. WESTING- HOUSE ELECTRIC CORPORATION. Nov. 18, 1965 [Dec. 7, 1964], No. 49019/65. Heading H2B. A circuit breaker comprises two interrupter assemblies, each consisting of a main switch (11); parallel arcing contacts (12); and a parallel resistor switch (13) which are operated in succession by individual fluid actuators, and a pair of isolator contacts (16) with fluid actuators (55) all mounted within a tank (2) filled with compressed gas (e.g. air at SF 6 ), the interrupters being controlled by a valve (72) operated electrically and under the control of an auxiliary switch (74) operated in accordance with the pressure in the operating cylinder of the isolator. The breaker is opened by energizing the trip circuit which energizes the coil (81) of a trip valve (72) through first contacts (83) of the auxiliary switch. This vents a pipe (84) causing a piston (36) to descend, opening main contacts (31, 32) and at the same time moving a valve member (85) to vent a passage (44) through pipe (84). This causes a piston (38) to descend opening the arcing contacts (19, 20) and moving another valve member (86) to vent passages (45, 47) and cause a further piston (46) to descend separating contacts (27, 28) to break the circuit of a parallel resistor (15). Piston (46) carries a valve member (87) which vents a pipe (90) and a pilot valve (91) which changes over to vent the operating cylinder (57) of the isolator (16) through a pipe (111). Venting of cylinder (57) operates the switch (74) opening contacts (83) so that the trip valve (72) is released, pressure in pipe (84) is restored and the interrupter contacts (11), (12), (13) all reclose; a bleed (a) on the pilot valve (91) retains this and the isolator in their open positions; a one-way valve (C) prevents pressure in pipe (90) being applied to operate the pilot valve (91). The isolator is reclosed by energizing a valve (71) through the now closed contacts (93) of switch (74). Valves (71), (72) are common to a number of phases and a one-way valve (B) is necessary to prevent operation of all isolators by the first interrupter to operate. The resistor switch (13) and the arcing contacts (12) are each provided with nozzle shaped fixed contacts which are also formed as blast valves which vent into tanks (14) connected to atmosphere through bushing insulators (4).

IPC: C25D3/18
Filed: 1965-11-23
Abstract: 1,150,888. Nickel electro-plating baths. WILMOT-BREEDON Ltd. Oct. 18, 1966 [Nov. 23, 1965], No. 49650/65. Heading C7B. In electro-plating with nickel from an acid bath containing nickel, sulphate and halogen ions, a buffer, and coumarin as a levelling or brightening agent, the halogen ions are constituted solely by bromide or iodide ions instead of chloride ions in order to increase the life of the bath by reducing the rate of oxidation of the coumarin during plating. Typically the chloride content of a known bath is replaced on an equimolar basis by bromide or iodide, these ions preferably being provided by nickel bromide or nickel iodide. In a specific example a bath is provided derived from a Watts nickel bath additionally containing coumarin by replacing the nickel chloride by a molar equivalent of nickel bromide, the bath being used at pH 3 to 5 at a temperature of 130‹ F. as for the Watts bath.

Abstract: 1,064,800. Printing processes. RANK XEROX Ltd. Dec. 16, 1964 [Dec. 30, 1963; Jan. 3, 1964], No. 51245/64. Heading B6C. [Also in Division G2] A double-sided copy of an original is pro duced by transferring tacky xerographic powder images of the original to both sides of a copy paper. The powder images are transferred to, or formed on, a non-stick surface and made tacky by exposure to the vapour of a solvent for one of the components of the powder. In one form (Fig. 5, not shown), the tacky images are transferred simultaneously to both sides of a copy paper under the influence of an electric field. As shown, metal drum 11 is formed with a layer of vitreous selenium photo-conductor which is coated either with non-stick silicone oil or a thin layer of polytetrafluoroethylene. A sensitizing charge is provided by corona discharge means 31 and the drum 11 moves past an exposure slot to receive the image of a moving microfilm 10. A development chamber 42 includes a toner dispenser 46 and cascade means. The developed image is subjected to the vapour of solvent 65 to produce tackiness which immediately dries when transferred to copy paper which is fed to rubber-covered pressure roller 71. After receiving an image on one side, the copy paper falls out at the top of roller 71 and is re-introduced at the bottom in an inverted position. Puffer 95 separates the leading edge of the paper from drum 11. A web 107 of soft absorbent paper cleans the drum and may be pre-treated with silicone oil to replenish the drum surface. A moist cellulose sponge 115 and a fluorescent lamp 69 remove the remaining charge. The sequence of operations can be controlled manually or by cams on shaft 29 (Fig. 2, not shown). In other forms, the developed image is transferred to a separate non-stick surface on a drum contiguous with the drum 11 (Figs. 1, 5 and 7, not shown) under the influence of an electric field. Alternate images can be made tacky on this drum, while the remaining images are transferred to a further drum to be made tacky thereon.

Abstract: 1,059,750. Automatic speed control. COMPAGNIE DES COMPTEURS. Dec. 3, 1965 [Dec. 30, 1964], No.51426/65. Heading G3R. A ship's propeller is driven by turbine 9 whose speed is controlled by a potentiometer 1 which is positioned at the bridge and provides a reference voltage Vo for comparison with signal V representing the propeller-speed and derived from tachometer generator 12. The error signal is limited by circuit 21 and adjusted by potentiometer 22 before application to summing circuit 23 which receives from tachometer generator 13 a voltage representing the speed of actuating shaft 7 or device 8 which operates the steam inlet valves. The signal is then converted to A.C. by circuit 24 for amplification by amplifier 26. A voltage representing propelleracceleration is applied to summing circuit 25 for damping control, the output of generator 12 being differentiated for this purpose. The output of the amplifier 26 is converted to a D.C. signal which is applied to either magnetic powder clutch 4A or 4B to open or close the inlet valve. A remote control arrangement may be interposed between the reference potentiometer 1 and the control circuit 2 which receives a modified reference signal whose rate of change is decreased if the reference potentiometer is set for increasing speed above a predetermined value. An amplifier receives a signal corresponding to the difference between a signal from the reference potentiometer and one from a second potentiometer which is driven by one or other of two pilot motors in a direction corresponding to the polarity of the output signal of the amplifier. The second amplifier is associated with a third which is driven in the same manner and provides the modified reference voltage. The transmission ratio between one of the pilot motors and the potentiometer driven thereby is controllable.

Abstract: 1,139,165. Producing synthetic thermoplastic fibres. K. SEIFFERT. 20 Nov., 1967 [21 Nov., 1966], No. 52635/67. Heading B5B. [Also in Division D1] Fibres of thermoplastic synthetic material are produced by heating a continuous moving layer of the material to fusing temperature, subsequently cooling the layer of material, and simultaneously drawing it apart in a direction transverse to the direction of movement. In one embodiment (Fig. 1) a film of thermoplastic material is embedded between two carriers 1 and 2 which are controlled by the pairs of rollers 3, 4 and 5, 6, rollers 3 and 4 being heated to fuse the raw material, and rollers 5 and 6 being arranged so that they may be displaced laterally over a large range so as to form fibres of different length. In another embodiment (Fig. 2) a film of synthetic material 7 is passed between two rollers 8 and 9, the latter being heated by a heater 10 so that the side of the material in contact with the carrier 11 and roller 9 is softened and at point 12 where the rollers move apart fibres are drawn. A cooling stream of air 13 coming from a pipe 14 having a wide slot nozzle 15 loosens the ends of the fibres attached to carrier 11 and cools them. When the fibres reach staple length they may be separated from the carrier by means of a cutting device. Stretching of the fibres may be effected by including a further pair of rollers between the pairs 3, 4 and 5, 6 of Fig. 1, whose distance apart is less than that of rollers 5 and 6. The fibres may be crimped if the rollers of one pair are made to alternatively approach and move away from each other. Materials mentioned which may be used to form fibres according to the method of the invention are polyvinyl acetate, vinyl acetate - ethylene copolymers, polyethylene, polyamides, copolyamides, polyurethane and polyvinyl chloride.
