This stress disappears at low temperature when the portion 3p assumes the full line shape.

Title: Improvements in electrical counting circuits employing gas discharge tubes
Inventor: BEZDEL WINCENTY
IPC: H03K23/82
Filed: 1954-08-11
Abstract: 785,216. Electronic counting - apparatus. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. July 27, 1955 [Aug. 11, 1954], No. 23352/54. Class 106 (1). [Also in Group XL (c)] Fig. 1 shows a two stable-state circuit in which resistor R1 has a value much greater than resistor R2 and in which the H.T. supply has a value between the breakdown and maintaining voltages of the cold-cathode gas tube VK. The trigger electrode is biased by a D.C. voltage, or a pulse waveform applied to lead 10, to a maximum value just below the triggering potential of the trigger gap of the tube. A train of steep-fronted positive going pulses are applied at input 11 such that the first pulse causes the tube VK to fire and capacitor C2 which was charged to the value of the H.T. supply discharges through the tube. A posi. tive output pulse, Fig. 2 (not shown), is produced across cathode resistor R2, when capaci. tor C2 has discharged only a very small current flows through resistor R2, as resistor R1 has a very large value compared with R2. When a second pulse on the input pulse train at 11 is applied, since the current in the tube is very small, ionization is transferred from the main to the trigger gap so that when the pulse ceases the tube is extinguished. Capacitor C2 now charges to the H.T. potential and a third pulse at the input fires the tube and gives an output pulse. Thus the circuit functions as a scale-of-two counter. Fig. 3 shows a multistage circuit counter circuit employing a cascaded connection of stages of the type described in connection with Fig. 1, and in which feed-back between tube VK4 and tubes VK2, VK3 via capacitors C3 and C4 respectively enable a count of 10 to be obtained.

Title: Improvements in or relating to electrical servo or follow-up systems
IPC: G05D3/14
Filed: 1944-11-23
Abstract: 604,914. Valve amplifying circuits. SPERRY GYROSCOPE CO., Inc. Nov. 23, 1944, No. 23380. Convention date, July 19, 1943. [Class 40 (vi)] [Also in Group XXXVIII] In a remote control system, signal voltages are applied to the grid of an electron tube, the cathode of which is coupled to means for providing degeneration and means for delaying the degeneration when a change in signal voltage occurs, so that the plate output comprises components proportional to the signal voltage, and rate of change of signal voltage. Fig. 1 shows a signal generator 1, the output of which is reversible in phase and is applied through transformer 19 to the grids of valves 21, 22. Alternating biassing potential is supplied to the grids from source 9 through winding 29 of transformer 26 and the anodes are supplied with potential in phase agreement from winding 25. When a signal voltage is impressed on the grids of valves 21, 22, the output of one increases and that of the other decreases, the resultant being applied to transformer 24. In order to provide a signal proportional to rate of change of displacement, resistors 35, 39 each having a resistance value of the order of magnitude of the impedance in the plate circuit of the valve, are connected in parallel with capacitors 38, 40 in the cathode circuits of the valves. Assuming that the signal is such as to cause valve 21 to become more conductive, the voltage drop across resistance 35 is greater than that across resistance 39. As .the signal voltage decreases in magnitude, condenser 38 delays change in the self-bias voltage across resistance 35, causing the output of the tube to decrease faster, thus producing components proportional to signal voltage and rate of change of signal voltage. The output from transformer 24 is fed through amplifying valves 41, 42 to one phase 49 of a two-phase motor, the other phase 51 being supplied from source 9. The ratio of the D.C. component to the A.C. in the primary of transformer 24 is controlled by varying the value of condenser 54. Due to the mutual inductance of the transformer windings a changing D.C. voltage in the primary produces a voltage in the secondary proportional to changes of D.C. voltage so that a further rate component and an acceleration component are applied to the motor. In a modification. Fig. 2 (not shown), the A.C. component is byepassed and only the D.C. component proportional to the displacement and rate of change of displacement is applied to the motor.

Title: Improvements in or relating to electric protective systems
IPC: H01H71/10
Filed: 1930-08-05
Abstract: 360,057. Protective cut-out arrangements. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, and ANDREW, T. S., 10, Appletree Gardens, Walkerville, Newcastleon-Tyne. Aug. 5, 1930, No. 23437. [Class 38 (v).] Relates to a protective system for a group of feeders, each with its individual circuit-breakers of relatively small interrupting capacity, all supplied through a group circuit-breaker of large interrupting capacity wherein the tripping of the individual circuit-breaker in the faulty feeder takes place only after the fault has caused the group feeder to open, as in Specification 297,702, [Class 38 (v), Electric switches &c.]. The invention consists in obtaining the correct sequence of operation without the use of field circuits. As shown in Figs. 1 and 2, the main circuit F containing the main overload circuit-breaker G has a branch feeder B containing the feeder circuit-breaker B<1>. The feeder supplies through a current transformer A<1>, a solenoid A having a core C with a lateral pin C<1> normally engaged in a cam-slot D<2> in the core-guide D. With excess current in the feeder due to fault, the core is raised and slightly rotated to bring the pin into line with the vertical slot D<1>. The excess current brings out the main circuit-breaker and the resulting loss of current in the solenoid A causes the core to drop and, through the links E, E<1>, knock out the trip of the feeder circuit-breaker. The group circuit-breaker may reclose after a time interval, automatically, and the feeder circuitbreaker may then be reclosed. The core of the feeder circuit-breaker may be reset with the pin C<1> in the slot by the opening movement of the circuitbreaker itself through a cam-operated lever. In a modification to deal with surges or faults outside the protected feeder, voltage-excited additional coil K<1>, Fig. 4, is used. The core of the coil K, in the raised position, serves to hold a latch lever M, M<1> under a pin J<1> corresponding to the pin C<1>. On fault, the pin J<1> is lifted, the group circuit-breaker opened and the latch lever swung clear, so that the current core may fall and trip the feeder circuitbreaker as before. In the event of a heavy surge, unaccompanied by a collapse of voltage, the pin will be lifted but on falling again will encounter the latch. In the event of a collapse of voltage, due to the tripping of the main circuit-breaker on fault in some other feeder, the current core remains latched in the raised position a projection M<3> on the latch engaging the side of the unraised pin. The current coil may be energized in accordance with the earth-leakage current.
