摘要： 591,738. Dielectric heating. BRITISH INSULATED CABLES, Ltd., QUAYLE, J. C., and JONES, P. May 12, 1945, No. 11969. [Class 39 (iii)] In a tool for spot heating insulating materials by dielectric losses, a central conductor 8, 9 and a barrel 1, 3 carried by a handle or other support 2, constitute two telescopic, co-axial conductors which are connected to a high-frequency electric supply, e.g., 1,000-10,000 megacycles per second, and form at one end two concentric electrodes 23, 38 to be pressed on the work, whereupon the tool telescopes against the action of a controlling resistance such as a dashpot 33, so that the effective electrical length of the barrel reduces and passes through one or an odd multiple of quarter of the wavelength of the electric supply. At this value the electric stress in the work is a maximum. Conveniently, the barrel has an initial length greater than one or an odd multiple of quarter of the wavelength by less than quarter of the wavelength, and.telescopes through approximately quarter of the wavelength. In the example shown, the barrel comprises telescopic elements 1, 3 guided by metal collars 4, 6 and by a piston 5 carried by the element 3. The ends of a metallic bellows 31 containing oil are closed by the piston 5 and the wall 32 of an air chamber 30 into which the oil can flow through an annular plug 35. Thus different plugs can be used to regulate the rate of telescoping of the tool. The oil can return through a discharge valve 37 as the tool returns to its normal length. The central conductor comprises an element 9 slidably received in an element 8 which is fixed to the element 1 by an insulating spider 12 having arms extending through slots 14 in the element 3. Screens 41 for the slots 14 are carried by the element 1 in electrical contact with the element 3. The element 9 includes the electrode 23 which projects beyond the electrode 38 and retracts, on engaging the work, against the action of a spring 21. A spring 18 between insulating annuli 11, 19 acts to return the tool to its normal length. The high-frequency supply is connected to co-axial conductors 24 and 29 attached respectively to the elements 8 and 1. The conductor 24 extends through apertures in the elements 1, 3. The mean diameter of the electrode 38 is preferably one quarter of the wavelength, e.g. 2 inches..The ratio of the diameters of the adjacent electrode surfaces may be 2 : 1.

摘要： A ceramic body, particularly for use in the manufacture of dielectrics for condensers, is made by mixing the powdered ceramic material with polyisobutylene, the mixture being then shaped and heated to drive off the binder and finally to cause the ceramic material to sinter. The polyisobutylene may be of an average molecular weight of 50,000-200,000, and it may compose 50-60 per cent. by volume of the total mixture. The ceramic material, e.g., rutile, may be incorporated by working on rolls heated to 100 DEG C., and then in a Banbury mixer, a vacuum being applied to remove entrapped gas. The product may then be calendered or pressed in moulds. Firing may be carried out in two stages in a single-chamber or two-chamber furnace, the first stage involving heating to 500 DEG C. to remove the binder, and the second requiring heating to 1400 DEG C. to sinter the ceramic material.

摘要： 562,830. Electric heating. BRITISH INSULATED CABLES Ltd.. WALTON, G. H., QUAYLE, J. C., and JONES, P. Jan. 1, 1943, No. 10. Addition to 554,176. [Class 39 (iii)] [Also in Group XXV] In a, machine as claimed in the parent Specification, the two sheets 1., 2 of insulating material are kept apart until they are close to the grooved rolls 3 and at the rolls are subjected to a high frequency electric field produced between the wires 7 and the rolls by using the wires as a resonant line of about a quarter wave length fed at the end remote from the rolls. The wires 7 may, as shown, be arranged in two similar groups to form the two sides of the line, being connected together at the low potential end 9 of the line and coupled near that end either inductively or directly to the terminals of an oscillator 19. Alternatively, the wires may form one side of the line and a stationary conductor is disposed parallel. with the wires to form the other side of the line. The conductor is connected to the wires at the low potential end and is coupled to the rolls at the other end.

摘要： 559,585. Wave guides. BRITISH INSULATED CABLES, Ltd., and QUAYLE, J. C. July 10, 1941, No. 8696. [Class 40 (v)] A wave-guide has the form in cross-section of a long narrow rectangle folded over in a smooth curve on itself. This shape may be obtained by providing a strip of T-section to form the centre while the outer wall is formed by strip 2, 3 of sheet metal, Fig. 2, or alternatively a single strip could be used and sprung over the head of the T. Fig. 3 shows a U-section using a central strip 4 and an outer casing 5, 6 of thin sheet metal. The guide may be made of non-metallic material, e.g. the normally solid polymers of ethylene with the inside metallized. With the guide of the section shown in Fig. 2 the wave may be led into the guide by an extension of the T- section with the head and leg of the T cut away to form a tapered line.

摘要： 555,645. Supply systems employing high-frequency currents. BRITISH INSULATED CABLES, Ltd., WALTON, G. H., QUAYLE, J. C., and JONES, P. Feb. 25, 1942, No. 2488. [Class 38 (iv)] [Also in Groups XI, V, XXIII and XXXVII] A hand tool for heating and joining thermoplastic materials comprises a pair of relatively movable electrodes 1, 2, Figs. 1 and 3, in insulating housings 3, 4 carried by the jaws 5, 6 of the tool. The electrodes are of square cross section and are connected to a switch 17 between the handles which controls the supply of high frequency energy to the electrodes. The strips of thermoplastic material 18, 19 to be joined are located by spring pressed stops 20 which are pressed into their recesses as the jaws approach one another when the material softens. Additional similar stops may be formed on the ends of the housings 3, 4, to control the width of the joint. A spherical or cylindrical mould in two parts may be fitted to the apparatus instead of the stripjointing mould, and small side channels may be provided to receive surplus material forced out of the mould, Fig. 6 (not shown). The insulating housings and stops may be of steatite, ebonite, or a borate glass containing mica such as " Mycalex " (Registered Trade Mark). A similar apparatus, Fig. 7 (not shown) is operated by a pedal instead of by hand pressure. The switch 17 is preferably inserted in the supply line to an oscillator generator or other frequency converter supplying high frequency energy to the electrodes and may comprise an oil filled tube 51, Fig. 8, the cap of which carries a spring loaded plunger 53 operated by the movement of the handles of the tool to close contacts 54, 55, the latter of which is carried by a spring loaded plunger 56 mounted in insulating guides 61. As the material becomes plastic under heat, plunger 56 descends and plate 58 is depressed against spring 63, contacts 59, 60 remaining closed until compression of the material is almost complete, when the spring contacts 60 have no further travel and further movement of the olunger 56 breaks the circuit and cuts off the high frequency field. On releasing the pressure, the plate 58 moves unward slowly, due to oil resistance, and contacts 54, 55 are opened before contacts 59, 60 are closed again. In a modification. Fig. 9 (not shown), the arrangement is such that the time at which the contacts 59, 60 open is independent of the rate of approach of the electrodes, since movement is transmitted between plunger 56 and plate 58 by a spring. In an alternative control, Fig. 10, a simple switch 17 actuated by movement of the mould parts is in series with a thermal delay switch 65 which closes the supply circuit 66, and then opens it after a period determined by the heater 70. The apparatus is suitable for materials such as polyvinyl chloride, the strength of field being adjusted to the nature and thickness of the material. The strength may be varied during heating by controlling the supply frequency voltage to the frequency changing apparatus by a rotary potentiometer, Fig. 11 (not shown) actuated by a bimetallic helix which is heated when the switch 17, Fig. 10, is closed. The field strength may be gradually increased or decreased, or first increased and then decreased as in Fig. 12. The output of the frequency converter is controlled bv a group of impedances 75a, 75d each controlled by a thermal delay switch 76a, 76d which successively short circuit the corresponding impedances 75a, 75b, and open the impedances 75c, 75d. Alternatively the helix 74. Fig. 11, could be replaced by a motor. Instead of controlling the supply of energy to the oscillator, the reactance of the tuning circuit may be varied.

摘要： 554,749. Vulcanizing indiarubber. BRITISH INSULATED CABLES, Ltd., WALTON, G. H., QUAYLE, J. C., and JONES, P. April 18, 1942, No. 5192. [Class 39 (iii)] Wire covered by an insulating rubber coating and by an outer coating of rubber heavily loaded with carbon black is continuously vulcanized while passing through successive coils c each of a few turns of spaced copper tubing, which are connected to an oscillator working at a frequency of 20-200 million cycles per second and are approximately in resonance with it. A strong magnetic field is produced, which generates eddy currents in the outer conducting layer thereby heating it. while an electric field between the different parts of the coil c extends through the inner insulating rubber and heats it by dielectric losses. The coils are enclosed in a metal casing d with a diametral insulating separator p, and insulating bushes f through which the ends of the coils are passed. A rubber gland j has a small clearance over the insulated wire, and a similar gland is provided at the opposite end of the casing or at the end of a series of adjacent casings. The wire is subjected to gas or vapour under pressure, admitted at 1.
