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.

Abstract: 1,098,635. Space satellites. GENERAL ELECTRIC CO. Aug. 6, 1965 [Aug. 6, 1964], No. 33855/65. Heading B7W. A space satellite which is stabilized by means having momentum applied to it, e.g. a closed circuit fluid system operated to flow in opposite directions by a pump, has a solar cell so positioned on the satellite that it operates the stabilizing means so that the satellite is rotated rapidly about its own axis twice in orbit to cause the main solar cells to face the stun. The satellite in end view comprises a triangular body 12 and carries on its rear vertical edges a pair of outwardly inclined solar pressure panels 14 which apply yawing stabilizing torques to the body which tend to set up prolonged oscillations. These are damped by a closedcircuit fluid system 26 operated by a pump 28 so that liquid is circulated one way or the other in the system to ensure adequate damping of oscillating movements of the satellite. The pump is energized by a plurality of solar cells, two, 32, 34, at one end and two corresponding cells at the opposite end, each respective pair being connected in parallel. Shades 40, 42 extend outwardly from the ends of the body sufficiently to ensure that the sun's rays do not fall on the cells when the satellite is facing the sun. A further cell 30 is positioned on the back of the body and is in circuit with cells 32, 34 and pump 28 (as in Fig. 4, not shown), so that when the satellite is in positions in relation to the earth and sun in which its attitude has to be changed to keep primary solar cells 20, 24 facing the sun (positions 66 and 76, Fig. 5, not shown), the energy from cell 30 operates the pump and causes rapid circulation of fluid in circuit 26 to cause the satellite to rotate. Means 16, 18 to damp oscillations in roll and pitch comprise a spherical housing in which is freely suspended by diamagnetic repulsion a sphere containing a magnet interacting with the local ambient magnetic field.

Abstract: 1,143,610. Automatic control systems for electrolytic apparatus. SPETSIALNOE KONSTRUKTORSKOE BJURO TYAZHELYKH METALLOV. Oct. 17, 1966, No.46287/66. Heading G3R. [Also in Division C7] The power supply to electrolytic apparatus of the type which includes a rotary cathode and which is used for the production of, for example, copper strip, is automatically controlled so that a pre-set ratio is maintained between the electrolyzing current and the rotational speed of the cathode, the electrolyzing current being additionally stabilized at the appropriate level for a given rotational speed. As shown, electrolytic apparatus 3 is supplied with direct current from a motor-generator 2 having a field winding 14 and has a rotary cathode 5 driven by an electric motor 6. The electrolyzing current is sensed by a detector 4 the output from which is applied to a comparator 11 which includes a magnetic amplifier and which also receives a reference signal from a source 10 and a signal, representative of the rotational speed of the cathode 5, from a tachogenerator 9. Variations in electrolyzing current due to changes in the resistance of the electrolyte cause the comparator 11 to produce an error signal which is applied over an integrating unit 12 and a magnetic amplifier 13 correctively to vary the field excitation of generator 2 so as to compensate for the said current variations. Further, the comparator 11 produces an error signal if the rotational speed of the cathode 5 varies and this error signal is again applied over the units 12 and 13 to regulate the generator 2 so that the ratio between electrolyzing current and rotational speed of the cathode is maintained constant. Suitable circuit arrangements for the system are described with reference to Fig. 2 (not shown).

In use, connections 3 and 4 of adjacent units are connected together, air being supplied to the interiors of all the housings in a row by a common fan, and the peripheries of adjacent housings being sealingly joined together where they abut. The connections 3, 4 in Fig. 7 would be joined by bellows (7) as in Figs. 4, 5 (not shown). Alternatively the connections may be longer and constructed to engage one within the other (Fig. 3, not shown), or merely to abut to enable coupling by a common sleeve. Fig. 7 shows one way of sealing the peripheral frame 21 of cell 1, which comprises coarse and fine filters 10, 11, to an enclosing rim 5 of the housing, using a gasket 12 and a mass 13 of cast material to fill the gap. Alternatively the edge of frame 21 is glued to the flat base of the housing, or the frame is recessed and encloses the base, to which it is sealed by cast material (23) (Figs. 8, 9, not shown). Figs. 10, 11 (not shown) illustrate how a filter cell 1 may be sandwiched between two pyramidal housings in mirror relation, air passing through the cell from one housing to the other.

Abstract: 1,229,191. Trueing grinding wheels. COVENTRY GAUGE & TOOL CO. Ltd. 17 May, 1968 [18 Feb., 1967], No. 7831/64. Heading B3D. [Also in Division F2] Apparatus for dressing a helically-ribbed grinding wheel 3 comprises a pair of dressing tools 2 traversible together in timed relation with rotation of the grinding wheel whereby the dressing tools enter between the flanks of the wheel rib form and are traversed back and forth across the rib form in dressing contact with corresponding rib flanks in at least one direction of the traversing movement, and means for imparting incremental feed to the dressing tools after each traverse in order to progressively advance the tools radially in relation to the rib flanks. Each tool 2, which may be a diamond dressing tool, is carried by a slide 6 movable along an inclined slideway 7 on a carrier slide 9, the latter slides being movable along a slideway 9a on a dresser head 1. An arm 15 is mounted on a pivot 16a on each slide 9 and at one end has a nose 17a engaging an adjustable screw 19 on its associated slide 6 and at the other end has a nose 15a engaging a surface 14 parallel to the axis of the grinding wheel 3 on a slide 10 vertically movable by a screw 11. Each screw has a pulley 12 and the pulleys are interconnected by a toothed belt 13 engaged by a pawl 22 actuated by an hydraulic piston-andcylinder device 21. The device is operated at each traverse of the dressing head 1 to cause the screws 11 to move the slides 10 and, via the arms 15, the slides 6 so as to provide an incremental feed of the tools. On the return traverse, an hydraulic device 23 operated in conjunction with the device 21 moves the slides 9 so that the tools are withdrawn from engagement with the grinding wheel. Variation of the form dressed on the rib flanks may be provided by a cam surface 31 on each slide engaged by a lever 32 mounted on a pivot 33 on the head 1. An eccentric pin 35 on each lever co-operates with an adjustable follower 36 on each slide 9 so as to superimpose an additional movement on the slide 9 as the slides 10 move vertically. The dresser head 1 is vertically adjustable on a carriage 42, Fig. 3, by an hydraulic piston-and-cylinder device 43 or a screw 44, and the carriage is reciprocable along a roller slide 46 on a base 47 to traverse the dressing head by a screw 27 which engages a nut 28 and is connected by gearing 29 to the means for rotating the grinding wheel so that the latter is rotated in timed relation to the traverse of the dressing head. The traverse of the dressing head may be modified by advancing or retarding the lead-screw during traverse of the head by means of a cam in the form of a sine bar 62, Fig. 2, engaging a follower 64 on a slide 65 slidable on the base member 47. The slide 65 is connected to a flexible band 67 passing round a member 69 on the lead-screw and connected to a spring. The member co-operates with a nut on the screw so that as the member is moved by the band, the screw is advanced or retracted axially to modify the traverse of the head caused by rotation of the screw (see Division F2).

Abstract: 1,230,215. Switch actuation; handles. WESTHEM CORP. Ltd. 18 Sept.,1968 [3 Nov., 1967], No. 44382/68. Heading H1N. An arm 12, Fig. 1, mounted on pivot pins 20 and which may actuate an electric switch, has an integral resilient arm 22 connected by an integral flexible web 26 to an arm 25 on fixed pivots 30, whereby the arm 12 is constrained due to the moment of the tensile force in the arm 22 about the pin 20. As seen in Fig. 1, the arm 22 tends to seek an unstressed position out of the plane of the arm 12. In the arrangement shown, the distance between the axes 18, 28 of the pivot pins 20, 30 is less than the length of the arm 25, whereby the line of action of the arm 25 goes over-centre of the pin 20 to reverse the bias on the arm 12. In a modification, the distance between the axes 20, 30 is greater than the length of the arm 25, whereby the actuator 12 is always biased towards its initial position. Projections 36 of the arm 12 engage the pins 30 to provide an end stop. The pins 30 may engage alternative holes in a fixed plate 32, whereby the arm 12 may have alternative operating positions. The ends of the pins 30 may also be rounded, whereby the arm 12 may be forcibly rotated to disengage the pins from the holes 34. The arm 12 may be of a thermoplastic material such as polypropylene.

Abstract: 1,265,948. Programmed control of machine tools. ING C. OLIVETTI & C S.p.A. June 3, 1970 [June 21, 1969], No.26873/70. Heading G3N. A numerical control system, responsive to a programme unit providing a series of position and speed orders in digital form incorporates an arrangement for deriving a position error and summating it with the speed command to provide a control signal for the speed of a servomotor. As shown, a programme tape 1, bearing position and speed orders is read by a reader 2 and the orders stored in corresponding registers Kp, Rv. The digital outputs of the registers are fed to digital-to-analog converters 5, 6 and the analog output of converter 5 is compared with an actual position feedback signal on line 11 from a servomotor 10 to derive an error signal E. The error signal E is then summated with the programmed speed signal E<SP>1</SP> from converter 6 to drive a control signal which is fed to an amplifier 9 controlling the servomotor 10. During initial movement the programmed speed signal E<SP>1</SP> predominates over the position error E but, in the final positioning phase, as the programmed speed signal falls to zero the position error E determines the control of the servomotor. Additionally for rapid movement, the position error E is fed to a meter 13 producing a signal when the amplitude of the error exceeds a given level which is used to enable a gate 15 to permit a constant quantity Q to be added to, or subtracted from, the contents of a register Ri in dependence on the sign of the position error. The digital value of the contents of the register Ri is subtracted from the corresponding value from the position register Rp in an adder 4. The contents of register Ri are sent to the converter 6 in place of the contents of register Rv through a gate 16 which is enabled when the contents of the speed register is a null. The contents of the speed register Rv is fed to the converter 6 through a gate 17 which is enabled via line 18 when the contents of the register Ri are nil.
