Patent GB-1335447-A (GB)
Title: Superconductor and method of production thereof
IPC: H01L39/06
Filed: 1971-04-19
Abstract: 1335447 Super-conductors NATIONAL RESEARCH INSTITUTE FOR METALS, DIRECTOR OF 19 April 1971 [9 Feb 1970] 21353/71 Headings H1A A5 and A4D A super-conductor is produced by forming a composite comprising a first member of Cu, Ag or Cu-Ag alloy which also contains 0À1 to 30 At. per cent or 0À1 to 10 At. per cent Si, and a second member of pure V or V-alloy containing 0À1 to 10 At. per cent Ti, Zr, or Hf, working the composite to shape and heat-treating to selectively diffuse the Ga or Si into the V to produce a layer of V 3 Ga or V 3 Si. The composite may be formed into a wire, tape or pipe by drawing, rolling or swaging. The core may be completely reacted and may comprise a plurality of filaments. The remaining Cu, Ag or Cu-Ag alloy forms a stabilizing layer on the surface of the super-conductor. Specific examples are described in which the composite is produced  by casting a rod of the normal metal containing Ga or Si, shaping on a lathe and boring one or more holes into which V rods are inserted, or by casting the normal metal round one or more V rods arranged in a mould. A plurality of the composite structures may be covered with Cu, Ag or Al followed by working to shape and heat-treating. For A.C. use the resistivity of the normal metal sheath may be increased by using a high proportion of Ga or Si in the starting material.

Title: Apparatus for testing for leakage
IPC: G01M3/10
Filed: 1972-05-08
Abstract: 1384164 Testing watch cases OMEGA LOUIS BRANDT & FRERE SA 16 April 1973 [8 May 1972] 21386/72 Heading G1S To test a watch case 14 for leaks, the case is placed in an upper chamber 7 connected by a manometric tube 9 to a larger lower chamber 8, each chamber having an inlet/outlet valve 11, 12 and a closed-ended manometric tube 13 being provided to measure the pressure in the apparatus. Valve 12 is closed and valve 11 opened to feed pressurized gas to the chamber 7 and, via the tube 9, to the chamber 8 which is partially filled with liquid 10. The valve 11 is then closed to allow pressures to equalize, then valve 11 is opened briefly to allow the liquid to rise in tube 9 to a zero mark 15 on a scale 16. Thereafter any leaks in the case 14 will result in a lowering of pressure in chamber 7 and a further rise of liquid in the tube 9. As in Fig.3 (not shown) an auxiliary  container (20) may be provided for supplying liquid to chamber 7 after this test such that the case 14 is immersed. Alternatively, as in Figs.4-7 (not shown), the chamber 7 can be permanently partly filled with liquid and the case 14 mounted on a plunger (36) for immersion. Then if valves 11 and 12 are opened to atmosphere, gas which has leaked into the case will leave the case and form a detectable train of bubbles in the liquid.
