A superconductor circuit, comprising a winding of a tube of superconductor material having an electrically insulating outer sheathing, is completed by electrically joining together the outer surfaces of the ends of the tube where there is no sheathing and leaving inlets and outlets for cooling fluid flowing through the tube independent of one another. As shown, Fig. 1, the circuit comprises a superconductor tube carrying the cooling fluid forming a coil 10 connected to a superconductive switch 16. The outer surfaces of the tubes 19, 21 extending from the switch 16 and the coil 10 respectively are electrically connected together by means of clamp members 20 which surround the tubes at areas free from the outer insulating sheath. The ends 23, 24 of the tubes extend from the clamping members 20 and are connected to a self-contained cryogenic coolant system which pumps liquid helium through the tube. An electrical lead 22 is connected to the clamping members 20 to provide a connection to an external circuit. The tubes 13, 15 at the other ends of the coil 10 and switch 16 are buttjointed and secured by a clamp 14 to which a second lead 17 is connected. The clamping members 20, 14 are covered with a layer of insulating material (not shown). Switch 16 comprises an enlarged diameter tube section surrounded by a coil 18 by means of which a magnetic field can be applied to drive the tube section normal. The insulating sheath provides electrical and thermal isolation and the whole circuit may be mounted in an evacuated container. The superconductor material may be a Nb-Ti or Nb-Zr alloy or may be Nb 3 Sn and the tube may be provided with a liner of high thermal conductivity metal such as copper. The liner may comprise a tube, Fig. 2 (not shown), or a solid core having a plurality of bores for the coolant, Fig. 4 (not shown). A further layer of high thermal conductivity metal may be inserted between the superconductor tube and the insulating sheath, Fig. 3 (not shown), and the superconductor tube itself may comprise alternate layers of superconductor material and high conductivity metal. The superconductor may be applied to the liner by codrawing, evaporation in vacuo, cathode sputtering, plasma spraying, or by electrolytic or chemical deposition. The clamping members may be of copper and may be further supported by a stainless steel fitting. The superconductor tubes may be welded together or soldered with indium. A further circuit for storing and recovering power from a superconductor coil is described, Fig. 7 (not shown). The clamping members 20 may be omitted, the outer surfaces of the superconductor tubes being welded directly together.

[Also in Division H1] In producing a multilayer coated film assembly having a pair of electrically conductive elements in different layers with a layer of electrically insulating material between them, after deposition of the first of said conductive elements the deposit is electropolished before deposition of the insulating materiaL Typically the coatings are formed by vapour deposition. As shown a polished glass plate 16 is coated with a layer 18 of SiO, a thin layer 20 of Cr or Ni, and then a layer 10 of Cu or Au forming the first conductive element layer. The desired circuit formation may be obtained either by depositing the material of layer 10 through a suitable mask or by chemically etching away, e.g. with FeC1 3  or Cr0 3  for Cu, portions of the layer through a resist layer formed for example by photographic methods or silk screen printing. After removal of the etch resist, the layer elements 10 are then electropolished in a viscous electrolyte by sandwiching the assembly between a pair of phenolic resin frames, the face of that frame which contacts the layer 20 being clad with a conductor, e. g. Cu, to which anodic connection is made. For Cu, the polishing electrolyte may be phosphoric acid with either sodium lauryl sulphate or sodium carboxymethylcellulose. Glycerol is unsuitable as a thickener if the layer 20 is Cr. For Au, the polishing electrolyte is ammoniated potassium cyanide together with rochelle salt, potassium ferrocyanide and sodium carboxymethylcellulose. The exposed areas of layer 20 are then selectively etched away, e. g. using a solution of AlCl 3 , ZnCl z  and H 3 PO 4  or of HCl for Cr, zinc pellets being included in the bath in contact with the Cr layer, or HCl for Ni. Layers 14, 22, 12 of SiO, Cr, Cu respectively are then deposited, masks being used in the metal depositions to provide the desired circuit elements. In place of SiO other insulating materials may be used, including mixtures of SiO and SiO 2 .

[Also in Division H1] An alloy contact is provided on a rare-earth semi-conductor body by depositing the alloy on the semi-conductor body, heating the alloy and the body in an inert atmosphere to the melting point of the alloy to cause the alloy to melt, and continuing the heating to cause the alloy to partially diffuse into the body, the alloy comprising a rare earth metal such as cerium, praseodymium, neodymium, lanthanum, gadolinium, terbium, dysprosium, halmium, erbium, thulium, ytterbium or lutetium, and a metal of good electrical conductivity such as gold, silver, copper, zinc, nickel, cobalt, palladium or platinum. In one embodiment a mixture of powdered lanthanum and silver is placed in a crucible in an inductively heated furnace in an argon atmosphere and fused to form an eutectic alloy. In a second embodiment rods of lanthanum are placed with gold foil on the hearth plate of a conventional D.C. furnace and the arc struck to form an ingot of alloy which is inverted and remelted at least three times to ensure homogeneity. A table of various alloy compositions is given. The semi-conductor material is an alloy of the equation Eu x RE 1-   x A where Eu is the rare earth europium, RE is a rare earth element, A is a chalcogen and 0<x< 1.

Abstract: 1,226,206. Domestic baths. H. G. PRESTON. 19 May, 1969 [30 May, 1968], No. 25920/68. Heading A4N. A bath 4 has a door 1 vertically slidable into an opening in one side of the bath, with sealing means (16), Fig. 3 (not shown) between side and bottom edges of the inner face of the door and the said bath side. A panel 5 having a corresponding cutout covers the said bath side, which side has a slot 15 below the opening into which the door may be pushed until the top 2 of the door is approximately at the height of the bottom of the opening, top 2 being level with the rim 3 of the bath when the door is raised. Vertical T-sectioned edges 11 of the door slide in T-sectioned slots (10), Figs 2, 3 (not shown), in the said bath side adjacent the opening and continuing into slot 15. The sealing means (16) comprises a sealing strip fitted into a groove down the inner faces of "necks" (12), Fig. 3, of the T-sections 11 and across the bottom of the door inner face, the strip also providing a friction grip to retain the door in the raised position when its inner face is stated to be substantially flush with the inner surface of the bath. Surfaces (13), Fig. 3, on the door extend obliquely from the "necks" 12 towards the inner face of the door and slide over surfaces (14) on the said bath side extending from the slots (10) obliquely towards the bath inner face. The bottom of slot 15 may be connected to the bath waste pipe. The bath is supported by cradles 16A having pegs 17 locating in recesses in the bath, other pegs locating in holes in bath panels 5, 6. Cradles 16A are formed from the same material as the bath, which material may be fibre-glass, high density polythene or cast iron.

Abstract: 1,230,100. Potted electrical components. ENGLAND HUGHES BELL & CO. Ltd. 16 Dec., 1968 [15 Dec., 1967], No. 57019/67. Heading C3F. [Also in Divisions H1 and H2] The insulation in potted electrical components, e.g. junction boxes, comprises at least one thermoplastic polymer and at least one plasticizer therefor, the composition being non- adhesive to metals, being solid at temperatures up to the maximum operating temperature of the component and being capable of forming a stable pourable liquid. Exemplified compositions are based on cellulose acetate butyrate with chlorinated diphenyl, dibutyl phthalate, cyclohexyl phthalate, methyl cyclohexyl phthalate, dibutyl sebacate, butyl stearate, methyl abietate, mineral oil, ester gum, castor oil and sorbitan mono-oleate as other specified ingredients.
