Patent GB-991718-A (GB)
Title: Superconductor memory cells
Inventor: BALDWIN JOHN PATRICK
IPC: H01L39/10
Filed: 1962-11-16
Abstract: 991,718. Superconductor devices. MULLARD Ltd. Nov. 12, 1963 [Nov. 16, 1962], No. 43465/62. Heading H1K. A superconductor device immersed in a refrigerant comprises a substrate carrying a film of superconductor having a portion which is narrow compared with K 1 α 3 /(α2)<SP>2</SP>; where K 1  is the thermal conductivity of the substrate; α 2  and α 3  are the heat flux per degree of temperature discontinuity for the film substrate and substraterefrigerant interfaces, respectively; the switching from the superconducting to the normal phase being effected by heat generated in the narrow portion by current passing therethrough. The device is arranged to be switched from the superconducting phase to the ordinary phase by the propagation of Joulean heat, and if the film is sufficiently narrow then fast switching times can be achieved. The device is normally run with a steady current passing through it which is insufficient to switch it from the superconducting to the ordinary state, but is sufficient to maintain it in its ordinary state by virtue of the joule heat generated thereby. Switching from the superconducting state to the ordinary state is effected by a momentary increase in current, which generates centres of resistivity which generate joule heat to complete the switch-over. Switch-over to the superconductive state is achieved by momentarily reducing the current. The super conductor may be of tin, indium, mercury, thallium or lead. The substrate may be of quartz, glass or synthetic fibre. The superconducting film may be vapour deposited on the substrate and reduced to a width of less than 10Á by electron beam etching. In a modification switching may be effected by modulating a magnetic field applied transversely to the superconductor. This may be achieved by the provision of a further conductor parallel to the superconductor through which switching pulses may be applied. The switching conductor, which may be of gold, silver, copper or a further superconductor, may be supported on the substrate being separated from the superconductor by a layer of silicon monoxide. The refrigerant is preferably liquid helium.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B25/12
Filed: 1962-11-20
Abstract: In a method of manufacturing flat glass of a desired thickness, a ribbon of glass is advanced along a molten metal surface, is diverted upwardly from said surface and a ribbon of glass is then drawn upwardly from the diverted glass by a tractive effort applied to the ribbon, the speed of drawing and the viscosity of the glass as the ribbon is raised being controlled such that the ribbon is attenuated to the desired thickness and is sufficiently stiffened to arrest further dimensional change when that thickness is achieved.  A ribbon of glass 27 is fed at a controlled rate on to the surface 11 of a bath of molten metal (e.g. tin or tin alloy). The bath is covered by a roof structure and has an adjustable front wall 13 defining a predetermined entrance 16 and a drawing chamber 20, 21 situated at the outlet end.  Temperature regulators 28, 30 in the molten metal and 29, 31 in the superstructure control the glass temperature so that on entry to the bath the glass is permitted to form a buoyant body by flowing laterally unhindered to the limit of its free flow, and as the ribbon advances along the bath it is cooled sufficiently to be raised from the bath. The ribbon is raised from the bath preferably with the aid of rollers 37, which also control its width, and the ribbon is drawn upwardly through the chamber into a vertical annealing lehr 34.  The speed of upward draw and the viscosity of the glass in the drawing chamber <PICT:1064328/C1/1> (through thermal regulators 36) are controlled. Alternatively, the updrawn ribbon 41 on emerging from the drawing chamber may be passed over a bending roll 46, Fig. 2, and thence into a horizontal annealing lehr 48.  The atmosphere above the bath of molten metal and in the drawing chamber is one inert to the molten metal.  In a further embodiment two ribbons of glass are advanced along a molten metal surface towards each other and diverted upwardly at their confluence to form a single ribbon of glass.  A seal such as described in Specification 1,017,752 may be used at the exit 26 of the drawing chamber and the inlet 16 to the bath.

Abstract: 1,214,920. Glass fibre manufacture. OWENS-CORNING FIBERGLAS CORP. 17 Sept., 1968 [22 Nov., 1967], No. 44164/68. Heading C1M. Apparatus for manufacturing glass filaments comprises a single melting and refining furnace 10, a feeder passage 11 receiving molten glass from the furnace, a cross channel 14 receiving molten glass from feed passage 11, a plurality of parallel laterally spaced feed channels 48 leading from the cross-channel 14 and an H- shaped channel configuration 16-16d connected to each feed channel 48, there being heating means in all channels, and each H- shaped channel having a plurality of orificed feeders along each of its branches, and there being means associated with each orificed feeder for attenuating molten glass into filaments. The cross-channel 14, central channel 50 of each H and each branch 52-55 of each H are heated by gas-burners located in the channel side walls above the glass, the burners being controlled by thermocouples immersed in the glass. In channels 14 and 50 the burners are located immediately above the glass surface, but in the branches 52-55 the burners are located at the top of the headspace above the glass. Waste gases from all channels are exhausted through stacks 70-73. The branches of each H are so aligned to form two spaced parallel rows of feeders 66 which are located in the ceiling of a forming chamber 20. The filament from each feeder 66 is drawn conventionally between shoots 150 located between elongated slots 146 in the floor of chamber 20 and elongated slots 156 in the floor of a washing room 22. A lower room 23 is provided in which waste glass from broken filaments is collected. Water from nozzles 121 is sprayed on to the fibres immediately after drawing, and the fibres then pass over a coating device 130. The temperature of the forming chamber 20 is partially controlled by cooling elements 198 and 202 (not shown). Each H-section is provided with an air-condition unit 170, 170a which is controlled for temperature and relative humidity (spray nozzles 171). This controls the temperature and humidity in chamber 20 and room 22, purges such rooms of dust, broken filaments and fuzz and enhances the drawing operation. Air is fed into room 20 through grilles 184 in its ceiling for uniform distribution and flow down shoots 150 into room 23 and into return pipe 170a, 188. The used air can be either completely exhausted or partly recycled. It is preferred to pass the air at at least 1000 to 1200 c.p.m.

Filed: 1965-10-22
Abstract: 1,089,720. Starting prime movers; control of motors. C.A.V. Ltd. Oct. 7, 1966 [Oct. 22, 1965], No. 44765/65. Headings H2H and H2J. To prevent overspeeding of the starter motor for an internal combustion engine the motor is arranged to be automatically de-energized when the I.C. engine is running. The starter motor 13 is energized over a contactor 12 which is closed when a manually operated switch 14 is closed to energize a solenoid 16 over a pair of normally closed contacts 17. The contacts 17 are associated with a solenoid 18 and each contact is carried on a separate support. During starting the heavy current through the solenoid 18 moves the two supports to an operative position without opening the contacts 17. When the engine is running the, current through the solenoid will be reduced to a value insufficient to hold the, supports in the operative position. Energization of a solenoid 15 when the switch 14 is closed is provided however so that one support does remain in the operative position when the current flow in the solenoid is reduced thus causing the contacts 17 to open to de-energize the solenoid 16 and release the contactor 12 thereby de-energizing the starter motor 13. The solenoid 18 may be in the form of a straight bar and is associated with the solenoid 15 and contacts 17 in a single assembly.

Filed: 1963-11-15
Abstract: 992, 535. Gyroscopic apparatus. LITTON INDUSTRIES Inc. Nov. 15, 1963, No. 45310/63. Headings G1C and G1N. A gyroscope includes a casing, liquid in the casing, a rotor and motor assembly 11 in the casing and electrostatic means for causing the assembly to rest in a null position in suspension in the liquid. The casing comprises a centre casing 13 and end covers 14,16 and the assembly 11 is generally spherical and supported inside the casing by the combined effect of the upthrust due to the liquid and the electrostatic means, the upthrust providing the major part of the supporting force. Lateral and angular movements of the assembly 11 from the null position in which the spin axis of the rotor coincides with the X-axis are detected by three pairs of diametrically opposed pick-offs carried in recesses in the casing 13 and the pickoff signals are fed to a circuit described in the Specification which supplies D.C. voltages to diametrically opposed pairs of electrostatic pads 19 and 21, 15 and 17, and 23 and 25 arranged in the casing or X<SP>1</SP>, Y<SP>1</SP> and Z axes the X<SP>1</SP> and Y<SP>1</SP> axes being displaced in the XY phase from the normal X and Y axes. These voltages correct lateral movements of the assembly 11 and angular movements are corrected by three diametrically opposed pairs of torques as 41, 45, Fig. 1 fed with appropriate voltages from the circuit referred to above. The assembly 11 is at earth potential and the electrostatic correction voltages are fed, by the circuit described to only one of a pair of pads, although voltages may be fed simultaneously to both pads of a pair if desired. The pads are initially positioned by use of a positioning ball of larger diameter than the assembly 11, the spaces behind the pads being filled with an epoxy resin, the pads being urged to contact the ball by means of adjusting screws or leaf springs, and the resin then being allowed to harden. When the ball is replaced by the assembly 11, the pads will then be correctly positioned. The pick-off assemblies are arranged as shown in Fig. 3 each with a flat coil carried by the assembly 11 and positioned between C-shaped polepieces 38a, 38b having windings supplied with a suitable A.C. voltage. With the flat coil positioned centrally no resultant signal will be developed in the flat coil, but movements along the AA<SP>1</SP> axis in the A and A<SP>1</SP> directions are arranged to produce signals respectively 180 degrees out of phase and in phase with the excitation voltage, and proportional to the displacement. Thus a signal indicative of the magnitude and direction of the displacement is provided. The torques each consist of a magnet as 45m carried by the assembly 11 and a coil as 45c mounted in the casing 13. Specification 958,229 is referred to.
