Title: Improvements in variable capacitors
Inventor: SPERRY LEONARD J
Filed: 1964-08-21
Abstract: 1,073,002. Variable capacitors. GLOBEUNION Inc. Aug. 21, 1964, No. 34363/64. Heading H1M. A variable capacitor includes a first member including two portions separated by a medium having a dielectric constant lower than that of the portions and having an electrode on one of the portions, and a second relatively movable member having thereon an electrode which is adjacent the opposite surface of the first member to that carrying the first electrode. In the minimum capacitance condition the medium provides a complete physical discontinuity between the electrodes. The arrangement enables the maximum to minimum capacitance ratio normally achieved in solid dielectric capacitors to be increased. The first member may comprise a ceramic rotor disc 28 consisting of two parts 30, 32 separated by an air gap 34, and carrying a metallic electrode coating 36 on the part 30. This disc 28 is pressed firmly into a resilient disc 18 and secured to it by epoxy cement. The disc 18 is secured inside a phenolic cap 12 by means of a tab 20, 24, which also makes connection with the electrode 36. The second member consists of a steatite stator 40, carrying a second electrode 42, which is connected to a terminal arrangement 44. The assembly is held together by a resilient member 50 secured by an eyelet 56, which passes through the structure and is secured to the tab 20, the eyelet 56 thus forming the second capacitor terminal. In use, rotation of the cap 12 varies the capacitance, the maximum capacitance condition being obtained when the two electrodes are in alignment and the minimum when they are displaced 180 degrees from each other and separated by the air gap.

Title: Improvements in and relating to wireless signalling receiving systems
IPC: H01Q11/02
Filed: 1921-09-30
Abstract: 192,346. British Thomson - Houston Co., Ltd., (General Electric Co.). Sept. 30, 1921. Aerials; multiplex signalling; directive signalling.-Relates to horizontal directive receiving aerials of the kind described in Specification 175,315 wherein the received energy and the ether-wave energy build up cumulatively along the aerial, to reach a maximum at the end of the aerial farthest away from the transmitting station, and consists in an arrangement whereby the actual detecting-apparatus may be located at the end furthest away from the actual point of maximum aerial current or at any convenient distance from that end. As shown in Fig. 2, the two conductors 1, 2 forming the aerial are connected to earth at the end 3 through a transformer 6, 7, so that signal energy reaching a maximum value at that end is transferred inductively through the transformer and travels back in opposite directions along the conductors until it is transferred through the coils 26, 11, 12 to two or more detecting circuits 13, 15, 17 and 14 16, 18. Undesired or stray energy flowing to earth at the end 4 is balanced out or neutralized by being fed back to the aerial in opposition through an amplifier 25, phase-adjusters 23, 24, and the coils 11, 12. A resistance 5 having a value equal to the surge impedance of the aerial is inserted at one or both earth leads to prevent reflectious effects. As shown in Fig. 2, the detecting-circuits 13, 15, 17 and 14, 16, 18 are located at a point between the two ends of the aerial length. Specification 180,683 also is referred to.

Title: Improvements in windscreen washers for vehicles
Inventor: TAYLOR RICHARD OLIVER
IPC: B60S1/50
Filed: 1957-11-07
Abstract: 903,472. Windscreen cleaners. TRICO FOLBERTH Ltd. Nov. 6, 1958 [Nov. 7, 1957], No. 34777/57. Addition to 866,218. Class 138 (1). A windscreen washer operated by a replenishable supply of compressed gas which is independent of the power supply of a vehicle has a metering chamber filled by liquid under gravity from a reservoir between each washer operation and discharged by the gas acting on the surface of the liquid in the chamber during each operation, the liquid inlet into the chamber being closed during each operation by a valve movable between the liquid and gas inlets so that it is blown against the liquid inlet by the gas. As shown, compressed air from a spare tyre 109 passes through a control valve 110 to the underside of stem 116 of the valve 118, lifting it and pressing it against the liquid inlet 114, the top surface of the valve 118 having a layer of resilient sealing material. Liquid is forced out of the metering chamber 106 through outlet 112 to nozzles 115. When the compressed gas supply is cut off, valve 118 returns under the influence of gravity, possibly aided by a spring 124 which may be of leaf or coil type (Fig. 2, not shown). A co-ordinator 146 (Fig. 4), responsive to liquid pressure in the tube joining outlet 112 and nozzles 115, is actuated by the flow of liquid through holes 148, past non- return valve 150 into space 152 where it raises membrane 154 and plunger 156 causing the compression of spring 158 and the bridging of contacts 162 connected to the wiper motor. The motor operates after the delivery of liquid is completed until the escape of liquid past needle valve 164 allows the return of membrane 154 and plunger 156 and the open circuiting of contacts 162. To prevent the co-ordinator from operating the wipers in the absence of liquid in the reservoir 102, a float valve 142 opens hole 140 so that when compressed gas is delivered it escapes via hole 140 and the vent in plug 138 without effecting the co-ordinator. The reservoir may be in the form of a plastic bag.

Title: Improvements in and relating to the treatment of chocolate and the like for coating sweetmeats and the like
IPC: A23G3/02
Filed: 1937-12-16
Abstract: 507,584. Coating confectionery. PRESCOTT, W. E., BAKER PERKINS, Ltd., and ANCIENS ETABLISSEMENTS A. SAVY, JEANJEAN, ET CIE. Dec. 16, 1937, No. 34888. [Class 28 (i)] In an enrobing machine the layer of chocolate flowing to the curtain forming position is cooled on one side to produce graining and means are provided to mix the grained with the ungrained chocolate. The invention is shown as applied to the curtain-forming means described in Specification 431,228, the said' means comprising a conduit 3 'having a slot 4 adjacent the lip of an inclined curtain-forming plate 5. A cooling-coil 6 is arranged under the plate 5, and may extend over the whole area of the plate. At the upper and lower ends of the plate are mounted rollers 7 and 8 around which is arranged an endless wire net band or apron 15, one lap of which lies close to the front face of the plate. The roller 7 is driven through a gear 11 and is connected to the roller 8 by a chain-and-sprocket drive. The lap in contact with the chocolate is moved preferably in the same direction as the chocolate flow, and at the same speed as, or slightly slower than, the natural flow. The operative lap of the band 15 is maintained in position by bars 16 carried on transverse supports 17. The grained and ungrained chocolate are mixed by the band 15 which serves also to equalize the temperature gradient by reason of the conductivity of the wire mesh. The operative lap of the mesh and the plate 5 may converge slightly in the direction of flow of the chocolate. The rollers 7, 8 may be mounted on a slide or reciprocating 'frame and given a longitudinal reciprocating movement either alone or in combination with a .transverse movement. The combined orbital movement may be communicated by a crank-pin. Alternatively, the band 15, or the operative lap thereof, may be given vibrations in a direction transverse to the plate and the amplitude of the vibrations may be adjusted to effect a mixing action upon the flowing chocolate. The band 15 may be replaced by a series of endless strings or narrow bands, or endless means may be dispensed with and the mixing effected by rakes movable transversely or longitudinally or both, or a pair of chains, one on each side of the plate, may be joined by bars which act as mixers in their travel down the plate. Moreover, the coil 6 may be dispensed with, and the cooling effected by a current of cold air directed upon the upper surface of the chocolate, and instead of supplying the chocolate from a single source, such as the slot 4, it may be supplied from two sources, one of which is pre-cooled.

Title: Method of joining superconductors
IPC: B23K31/02
Filed: 1970-07-17
Abstract: 1322799 Welding by pressure and fusion THOMSON-BRANDT 17 July 1970 [18 July 1969] 34902/70 Heading B3R [Also in Division H2] In making a superconductive joint having superconductive properties superconductors are joined together by metallurgical bonding and the joint is treated by cold working and heating to regenerate its superconductive properties. Superconductors clad with copper are stripped of the copper at their ends and the ends are joined by an electron or laser beam in a butt or lap joint. The fused zone is cold rolled or hammered and heat treated, e.g. in the case of NbTi heated at 400 C. for 20 hours to restore the superconductivity of the joint. The bared ends may alternatively be joined by placing them alongside one another in a tube of the same superconductive material as that of the ends to be joined and the assembly is compressed to effect cold welding. In another alternative an element 7, Fig. 1, of the same superconductive material as the ends 1, 2 is friction welded between the bared ends 1, 2 of the superconductors. Superconductors 8, 9, Fig. 2a, clad in copper 10, 11 and insulation 12 either single or multifilament, have their end faces pressed together for cold welding.

Title: Improvements in and relating to liquid atomizing devices
IPC: B05B15/522
Filed: 1937-12-16
Abstract: 492,852. Atomizers. HUGHES, R. M. (Parks-Cramer Co.) Dec. 16, 1937, No. 34905. [Class 69 (iii)] A self-cleaning atomizer comprises conduits for liquid and compressed gas respectively, and is provided with relatively movable outlet nozzles for the fluids, the outlet members being positioned by the compressed gas to co-operate in maintaining continuous atomization of the liquid, and means responsive to changes in pressure of the gas incident to the interruption of the supply thereof to cause the outlet member of one of the conduits to penetrate and clean the other outlet. The atomizer comprises a head 1 provided with a nipple 3 for connection to a compressed air supply leading by an inclined passage 5 to a whirl chamber 6 and carrying a cap 7 provided with a central spray orifice 8. The rear part of the head 1 is secured to a casing 10 formed in two parts connected by a nut 21. Between the two parts is clamped a flexible diaphragm formed of a synthetic resin such as sold under the trade names Neoprene and Prenite. To the diaphragm is attached a tube 27 carrying at its outer end a liquid nozzle 28 which forms a cleaner for the atomizer nozzle 8. The inward movement of the nozzle 28 is limited by a flange 34 engaging the end of a nipple 12. Access of air to the chamber 17 is effected through a passage 32. The rear part of the casing forms a cylinder 26 in which is a hollow piston 39 having a flange 43 engaging the outer part of the diaphragm 16 and acted on by a relatively strong spring 42 and carrying a valve 45 controlling the liquid inlet and also a triangular rod 36 carrying a needle 37 for cleaning the liquid nozzle. Within the piston is a light spring 44 bearing against a collar 31 attached to the tube 27 between which and a flange 30 the diaphragm is clamped. On admitting compressed air to the apparatus the inner part of the diaphragm moves against the action of the spring 44 and the nozzle 28 is withdrawn until the part 34 engages the nipple 12. Rise of pressure now causes the outer part of the diaphragm to engage the flange 43 and force the piston 39 back against the action of the spring 42, withdrawing the needle 37 from the nozzle 28 and simultaneously opening the liquid valve 45. In a modification, the atomizing outlet may be formed in a flat disc adjustably clamped on the spray head.
