Title: Superconductive circuit
IPC: H01L39/10
Filed: 1969-03-15
Abstract: 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.

IPC: G11B7/1381
Filed: 1975-11-11
Abstract: In an apparatus for reading a record carrier on which information is stored in an optically readable structure, the radiation which is supplied by the radiation source is split into a read beam and an auxiliary beam for determining the focussing of the read beam on the record carrier. Said auxiliary beam is intercepted by two radiation-sensitive detectors. By disposing a radiation-absorbing knife between the radiation source and the Wollaston prism a part of the auxiliary beam is blocked. Thus, an accurate indication can be obtained of the magnitude and the direction of a focussing error.

Title: Micrometer head for internal measurement instrument
IPC: G01B3/18
Filed: 1977-06-22
Abstract: In a micrometer head for an instrument for measuring internal dimensions there is included a casing in which at least one measurement contact piece having an inclined base is radially mounted in a slot or groove. The contact piece is driven by the axial displacement of a measuring cone and is maintained in contact with the inclined lateral surface of the cone by means of a return member. The axial displacement of the measuring cone, the base of which is guided in an axial cylindrical recess of the casing, is effected by the thrust of a spindle which has a micrometer screw mounted thereon, the screw being engaged in a threaded member connected to the casing. The cone and spindle have coaxial axes of rotation, and the cone, spindle and micrometer screw are so arranged that the path of movement of the inclined base of the contact piece on the cone is in the form of a tapered ramp having a long length and shallow inclination, the movement being caused by the combined axial and rotational movement of the cone. The cross section of the spiral ramp is formed at least by the contact line of the inclined base of the contact piece with the cone.

Abstract: Fibres of limited length form strip-shaped regions of higher and lower fibre density which are arranged in an alternating sequence adjacent and parallel to one another. The fibres are present in a uniform distribution in the said regions. At least some of the fibres extend beyond the limits of adjacent regions. The majority of the fibres or fibre parts (20) in the strip-shaped regions of higher fibre density are folded transversely to the strip in a zigzag-like manner (22). The segments of the folded fibres are arranged at least approximately parallel to one another and are oriented virtually in the longitudinal direction of the strips. The majority of the fibres or fibre parts in the strip-shaped regions of lower fibre density are oriented transversely to the strip. The quotient Tensile strength transversely to the strip direction DIVIDED Tensile strength in the strip direction always has a value of less than 2. The composite textile material is produced by introducing a carded fibre fleece (31) between a stretched screen (32) and a set of strip-forming bars (33) and by directing, for example via nozzles (35), a flowable medium, preferably water, onto the strip-forming bars.
