Title: Improvements in cable terminations
Inventor: EDWARDS DEREK REGINALD
IPC: H01B12/00
Filed: 1967-11-30
Abstract: 1,227,350. Electric couplings. BRITISH INSULATED CALLENDER'S CABLES Ltd. 29 Nov., 1968 [30 Nov., 1967], No. 54609/67. Heading H2E. A termination for a coaxial superconducting cable comprises a plurality of coaxial conductors electrically connecting the conductors of the cable to those of a coaxial terminal, a tubular insulating envelope sealed at one end and axially movable relative to the cryogenic envelope of the cable, and sealed at the other end to the coaxial terminal; and insulating spacing and vacuum sealing means between the terminal conductors, the termination being so shaped that it reduces transfer of heat by direct radiation from the conductors of the terminal to those of the cable. In a superconducting cable comprising three tubular conductors 1, enclosing an evacuated space 5 and separated from each other and from an outer tubular cryogenic envelope 2 by annular evacuated spaces 3 (the spacers not being shown), each of conductors 1 is welded at 7 to a separate part-spherical conductor 6, which itself is welded at 9 to a conductor 8 of the coaxial terminal. The conductors 6, 8 are cooled by an internal cryogenic fluid duct. The sinuous passages between the conductors prevent direct radiation reaching the cable conductors. The coaxial conductors 8 increase in diameter from the point 9 to a maximum diameter, after which they become cylindrical, the cylindrical portion being either formed integrally with the first portion, or formed separately and welded on, so that as the temperature rises away from the superconductive state, the conductors still carry the same current. At the point where the conductors 8 emerge into the atmosphere, they are spaced apart by annular insulating spacers which also form vacuum seals. Inside the innermost, spacer is a central cryogenic fluid supply duct 12, there being an expansible member 13 to permit said duct longitudinal movement. A similar member 24 permits the tubular glass insulator 25 to move longitudinally relative to the cryogenic envelope 2, there also being provided thermal and electrical shields 26 to cut off radially-entering radiation. The duct 12, which has two heat shields 14, 15, feeds a stainless steel generally spherical manifold 16, through the walls of which pass glass cryogenic fluid distributing ducts to the hollow conductors 6. The ducts are allowed relative radial movement by the expansible members, 18. The conductors exposed to the atmosphere are provided with glass outlet ducts 22, with corona shields 23 for the cryogenic fluid. The ducts for cooling fluid may alternatively be secured externally to the conductors, in which case they may also act as conductor spacers. The sinuous spaces are formed by the conductors of the cable and/or the termination first increasing and then reducing in diameter. When the innermost conductors of the cable and the termination are both evacuated tubes, a heat shield may be formed by staggered baffles projecting from the tube walls.

Abstract: 1361979 Hot gas engines UNITED KINGDOM ATOMIC ENERGY AUTHORITY 29 Nov 1972 [9 Dec 1971] 57243/71 Heading F1S In the embodiment shown the working spaces of the engine 1 are filled with helium gas and in operation heat is continuously applied to the hot chamber H by way of electrical elements 80 and is extracted from the cold chamber C by pumping air to and from the space 46. The helium gas is caused to move between the hot and cold chambers H, C in a reciprocating manner and with a cyclic change of temperature and pressure by oscillation of the displacer formed by the inter-connected inner walls 3, 4 and the regenerator 2. The cold outer wall 8 is then caused to oscillate by pressure changes occurring in the displaced gas. The displacer 2, 3, 4 and the cold outer wall 8 oscillate with a relative phase difference. Oscillation of the cold outer wall 8 causes oscillation of the power and extension shafts 65, 67. This causes alternating electrical current to be generated by the transducer 68. Feedback of energy is achieved by forces derived from the shafts 65, 67 by deflection of the flexible bars 71, 73 being transmitted through the rods 77 the beams 59 and the rods 60 to displace the inner walls 3, 4. The heat source may be a radioisotope heat source or may burn non-nuclear fuel. The working medium may alternatively be hydrogen. Resonant operation is mentioned. Specification 1252258 is referred to.

Abstract: 1,186,120. Automatic control of refrigeration. TRANE CO. Dec.9, 1968 [Dec.18, 1967], No.58292/68. Heading G3R. Fluid-pressure in the refrigerant condenser of a refrigerator is maintained uniform by an electrical resistive transducer, responsive to the fluidpressure, which controls a gated semi-conductor switch in the supply to an electric motor driving a condenser cooling fan. As shown, when the temperature inside a refrigerator 12 falls below a predetermined value a bellows 36 closes the electrical supply circuit to a motor driven compressor 14 which circulates refrigerant through an evaporator 20 and a condenser 16. A bellows 48, responsive to refrigerant pressure on the outlet side of the compressor, compresses and thereby varies the value of a crystal or semiconductor resistor 50 in series with a condenser 42 so that the period during each cycle that the condenser voltage exceeds a value sufficient to render a controlled semi-conductor 40 conductive is dependent on the fluid-pressure. Since semiconductor 40 is in series with the supply to a fan motor 32 the speed of the latter, and hence the cooling of condenser 16, is adjusted to counteract changes of refrigerant pressure. If, however, the pressure does become excessive, a pressureoperated switch 38 opens to stop compressor 14.

Abstract: 1326779 Lasers YISSUM RESEARCH DEVELOPMENT CO OF THE HEBREW UNIVERSITY OF JERUSALEM 10 Dec 1970 [19 Dec 1969 26 Oct 1970] 58780/70 Heading H1C A gas discharge laser has the gaseous active medium contained in a continuous or sectioned electrically conductive tube which is insulated from the discharge electrodes. By using a metal tube which is at a floating potential instead of an insulating tube the discharge voltage necessary may be less. In the twin tube arrangement of Fig. 1 a mixture of CO 2  and He is flowed through inlets 22<SP>1</SP>, 20<SP>1</SP> and common outlet 2<SP>1</SP> of a composite discharge tube made up of copper tubes 8, 10 insulated by spacers 12, 14 and 16, 18 from tubular cathode 2 and anodes 4 and 6 and end pieces 20, 22 carrying mirrors 26, 24. Cooling is by means of water flowing through jackets 28, 30 and the anodes, cathode and end pieces 20, 22 may also be cooled. Alternatively the tubes 8, 10 and electrodes may be formed with internal ribs extending axially thereof to improve cooling, Fig. 2 (not shown). Instead of two arms the laser may comprise only two electrodes and one metal tube or more than two arms. Modulation of the laser output intensity may be achieved by modulating the wall potential e.g. by means of the signal from a microphone, by applying the signal between the cathode/anode and metal tube wall or between the anode and cathode. The amplitude modulated output of the laser is detected and the resultant audio signal fed through an amplifier to a loud-speaker. Since the output power of a metal tube laser cannot be increased by merely increasing the length of the tube, there being an optimum tube length, this can only be achieved by using a plurality of metal tube sections each of optimum length and the effect of which is not to substantially increase the discharge voltage. The arrangement of Fig. 4 (not shown) includes a twin tube arrangement including two symmetri - cal arms each containing two optimum length metal sections. A common cathode and two anodes are provided as in Fig. 1. Cooling is by means of water jackets and the active medium flowing through the tube is a CO 2 , N 2 , He mixture.
