Title: Superconducting switching elements
Inventor: HYMAN ROBERT ANTHONY
IPC: H01L39/20
Filed: 1959-08-17
Abstract: 880,459. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Aug. 12, 1960 [Aug. 17, 1959], No. 28013/59. Class 37. The Figures show steps in the manufacture of a superconducting switching element. Initially, Fig. 1a, parallel strips 2 of niobium are evaporated on to a single crystal 1 of silicon carbide acting as a heat-conducting insulator. A layer 3 of silicon monoxide is then evaporated to cover the middle of the niobium strips. Next (Fig. 1c) a single strip 4 of tantalum is evaporated on to layer 3. Fig. 1d shows a further layer 5 of silicon monoxide over conductor 4. Finally (Fig. 1e), parallel strips 6 are evaporated on to layer 5 to join the ends of strips 1, thus forming a control solenoid encircling gate conductor 4. The silicon carbide crystal may be replaced by mica; the niobium by lead, vanadium or tantalum, and the tantalum by tin indium or vanadium, but the transition temperature of the control solenoid should be higher than that of the gate wire.

Title: Improvements in or relating to electric circuit arrangements
IPC: H04L12/26
Filed: 1966-06-23
Abstract: 1,130,460. Telegraphy. SIEMENS A.G. 23 June, 1966 [24 June, 1965], No. 28106/66. Heading H4P. In an arrangement for generating distorted telegraph signals, each pulse in a sequence of pulses triggers a variable delay whose output and input feeds an arrangement comprising a plurality of gates. The output of the arrangement of gates is a telegraph signal having certain bits lengthened and others shortened. A first embodiment, Fig. 4 (not shown), comprises a shift register stepped by clock pulses at bitrate. Each stage of the register is connected to a monostable circuit which has a variable relaxation time and which forms the variable delay. The stages are also connected to the gating arrangement, as is the output of the delay. The gating arrangement feeds a connection matrix from which are tapped off outputs corresponding to the various telegraph combinations. The distortion is such that each Mark-Space transition is delayed and each Space-Mark transition undelayed, or vice versa depending on the delay set in the monostable circuit. In a second embodiment, Fig. 5 (not shown), known circuitry generates an undistorted character which is then distorted by a gating arrangement fed by bit-rate clock signals, the undistorted telegraph signal, and the output of the variable delay fed by the telegraph signal.

Title: Improvements in integrating apparatus for measuring instruments
IPC: G01F15/02
Filed: 1929-09-20
Abstract: 340,217. Integrating -apparatus. YOUNG, A. E., 1524, Asbury Place, Pittsburg, U.S.A. Sept. 20, 1929, No. 28583. Convention date, Aug. 1. [Class 106 (iv).] Apparatus for making a summation of, or for determining the resultant of a plurality of variable quantities comprises a dual device including two rotatable and coaxial members intermittently united for simultaneous rotation about a common axis by electromagnets which are intermittently effective. The differential pressure from an orifice gas meter is transmitted to a piston which moves a pivoted lever 2 the long arm of which ends in a slot in which works a block 3 guided on a vertical guide 4. A drum 5 loose on a shaft 10 is driven by a clockwork 6 and carries on its non-conducting surface two contact strips 8, 9 of which the strip 8 extends longitudinally while the strip 9 is so curved that the circumferential distance between the strips varies as the square root of the distance of the block 3 from a zero point. When the differential pressure in the gas main is zero, the lever 2 is inclined upwardly from left to right, and as the pressure increases the lever swings downwardly. When the brush 7 carried by the block 3 meets the strip 8 the circuit of two solenoids 14 is made and spring arms 12 on the drum 5 are drawn in to engage the teeth of a wheel 11 on the shaft 10 thus clutching the drum to the shaft 10. As the arms move in, they brush past latches 15 connected by a spring 16 and these spring back behind the arms 12 locking them to the wheel 11. The solenoids 14 are only energized while the brush is in contact with the strip 8. When the strip 9 is met, solenoids 17 are energized and the latches 15 are moved against the influence of the spring 16 to release the arms 12 which spring outward declutching the drum. The shaft 10 has thus been rotated proportionately to the square root of the pressure difference during an interval of one rotation of the drum. This movement of the shaft may be transmitted to a registering mechanism, or to compensate for density the shaft 10 may carry a second drum 55 having similar strips 88, 99 and a lever 22 moved proportionately to the static pressure moves a block vertically carrying a brush co-operating with the strips 88, 99 so that a shaft 100 is moved proportionately to the product of the square roots of the static pressure and the differential pressure and a registering mechanism 23 actuated to secure these for successive intervals. An additional drum may co-operate with a temperature arm to give a correction for temperature.
