Filed: 1975-04-25
Abstract: 1505888 Hoses GUMMI EHLERS GmbH and CONTINENTAL GUMMI-WERKE AG 25 April 1975 [29 April 1974] 17192/75 Heading F2P An electrically conductive hose, especially suitable for use for conveying fuels in fuelling plants, is made of rubber or rubber-like plastics material and has embedded in the wall thereof textile reinforcing plies and an intermediate layer made of an electrically conductive elastomer and having a maximum thickness equal to the thickness of the plies. The hose is constructed from a mesh-covered or braided hose blank and a rubber outer layer. The intermediate layer may be sprayed directly on to the blank, painted on in solution, wound helically as a foil strip or band or, rolled on the inside surface of the outer layer in the form of a sheet or foil and then applied together with the outer layer on to the hose blank. Preferably the intermediate layer is made from a rubber mixture including carbon black and having an electric resistance of between 10<SP>1</SP> to 10<SP>2</SP> ohm/ cm. and is adhesively connected to the reinforcing plies.

Patent GB-591999-A (GB)
Title: Improvements in or relating to the production of textile yarn
IPC: D06M15/39
Filed: 1944-09-09
Abstract: Twistless yarns are produced from staple fibres by impregnating a sliver with an aqueous dispersion of a synthetic resin in a lower polymer form, which is stable on further polymerization to washing or dry-cleaning, subjecting the sliver to tension to parallelise the fibres, drying, and heating to further polymerize or condense the synthetic resin.  Adhesive substances such as starches, gums, dextrine, casein or gelatine may be added to the dispersion. Tinting, dulling, waterproofing, fireproofing or antiseptic agents may also be added.  In an example, fibres are first made into a sliver and then passed through a trough containing a mixture of 16 parts by volume of a 46 per cent dispersion of a urea-formaldehyde modified alkyd resin pre-condensate in glycol mono-ethyl ether, 1 part of ammonia (specific gravity 0.910) and 143 parts of water. From the trough the sliver is passed between squeezing rollers, stretched and dried at 180 DEG  F., then caused to travel for three minutes through a chamber at 250 DEG  F. to effect polymerization. According to the Provisional Specification, natural resin or a mixture of natural and synthetic resins may be used.  Specifications 338,381, [Class 120 (iii)], and 512,558 are referred to.

Abstract: 819,865. Fishing apparatus. JONASSON, A. June 7, 1956 [June 15, 1955], No. 17263/55. Class 48. Apparatus for catching fish in a continuous manner comprises a net 10 adapted to be suspended from the fishing vessel and having an open mouth, means such as a flexible pipe 17 attached to the end of the net for conveying fish from the net to the vessel and a plurality of flexible supporting means connected to the net mouth adapted to be relatively shortened and lengthened so as to reverse the direction in which the net mouth faces relative to the vessel. The net mouth is formed by a square frame constituted by longitudinal members of lattice construction. A steel hawser 15 is connected to each corner of the net mouth, the two hawsers on one side of the mouth being passed to the bow of the vessel and the other two to the stern. Two controlling wires 16 extend from the bow and the stern to the net mouth. Further wires 18 extend from the ship to the end of the net and to the net mouth. The flexible pipe 17 passes over a wheel 19 to a pumping unit 20 at the stern. By moving the wheel 19 along a rail on the gunwale the length of the flexible pipe extending downwardly into the water is altered. The netting is supported by eight wires which extend from the frame at the net mouth through a smaller frame at the middle of the net to the reduced end of the net. Two narrow plates extend along two opposite members of the frame at the net mouth and assist in keeping the net down.

Abstract: 1,188,792. Laminates. DUNLOP CO. Ltd. 18 April, 1967 [20 April, 1966], No. 17393/66. Addition to 929,180. Heading B5N. A method of making mechanical belting having a surface comprising polypropylene, comprises subjecting the surface of a polypropylene sheet, e.g. in the form of a film, a fibrillate or a woven fabric to the action of a liquid, e.g. a hydrocarbon which is capable of dissolving the polypropylene at elevated temperatures only, the liquid being at a temperature at which it is a solvent for the polypropylene but below the melting point of the polypropylene and the time of treatment being such that if subsequently freed from the solvent, the treated surface has a matt white appearance; cooling the sheet while still wet with liquid, to a temperature at which the liquid is no longer a solvent for the polypropylene, and then assembling the sheet with its treated surface in superposed relationship to a belting reinforcement ply to form a surface layer thereof, the assembly including a layer of a vulcanizable composition between the sheet and the reinforcement ply, the vulcanizable composition comprising an elastomer, e.g. natural rubber compatible with the polypropylene, and subjecting the assembly to pressure at a temperature at which the elastomer becomes vulcanized but is below the melting point of the polypropylene. The reinforcement ply or plies may be of textile material, e.g. cotton duck, may contain metal reinforcements and may be embedded on the elastomer. Alternatively, a thin layer of the elastomer may be applied as a calendered or extruded film or by topping or frictioning.

Filed: 1926-07-17
Abstract: 278,812. Hinton, N. P., Bell, H. G., and Metropolitan-Vickers Electrical Co., Ltd. July 17, 1926. Thermionic amplifiers.-In a high-frequency amplifier employing a tapped coil and balancing condenser for preventing self-oscillation, a damping winding is associated with the tapped coil for the purpose of eliminating parasitic oscillations. As shown in Fig. 1, the tapped coil 12, 13 is tuned by a condenser 11 and is connected at one end to tha plate of the amplifying valve 10 and at the other end through a balancing-condenser 16 to the grid of that valve. The centre tap is connected to the plate battery and is thus maintained at zero highfrequency potential. The 'damping-coil is in two equal sections 27, 28 wound in opposite directions on the respective halves 12, 13 of the main coil. Currents circulating in the tuned circuit 11 - - 13 produce no resultant voltage in the damping-coil, but other undesired currents (e.g. currents of opposite phase in the two sections 12, 13) are damped by the current induced in the damping-coil. This coil may be of resistance wire, and its circuit may be completed by a shortcircuit, a resistance, or by the capacity of its windings relatively to the main coil. When several stages of amplification are provided, the damping coil may be omitted at alternate stages. The damping-coil may be used in connection with a tuned intervalve circuit, the coil of which is connected at its centre to the filament, at one end to the grid of a valve, and at the other end through a balancing-condenser to the plate. As shown in Fig. 3, the main coil sections 12, 13 are wound in opposite directions, and the damping-circuit comprises an intermediate coil 37 closed through a resistance 38.

Methods of sighting.-A shaft A at the transmitting station of a sighting system carries a drum A' provided with a series of distance graduations, and drives a transmitter B and the disk R of a commutator switch. The transmitter B drives synchronously a receiver D operating a pointer D<1> co-operating with a mark e' upon a disk E. The disk E is operated from a shaft H which also drives a transmitter J and a sighting- device N<1>. The transmitter J drives synchronously a receiver Q connected to the contact arm Q<2> of the commutator switch. The disk R carries two contacts r<1>, r<2> connected in the circuits of lamps W, W<1> respectively and adapted to illuminate direction arrows x, y. When the shaft A is operated to drive the pointer D<1>, the lamp x or y is energized, according to the direction of rotation, before the pointer D<1> has made a complete revolution. The operator at the receiving station operates quickly the shaft H in the appropriate direction until the lamp x or y is de-energized, after which the shaft H is operated slowly until the pointer D<1> registers with the mark e'. Lamps in series with lamps W and W<1> may be provided at the transmitting station.
