Patent GB-1220744-A (GB)
Title: Improvements in or relating to logic devices
Inventor: UBERSCHLAG JACQUES
IPC: H03K19/00
Filed: 1968-05-14
Abstract: 1,220,744. Transistor two-state circuits. COMMISSARIAT A L'ENERGIE ATOMIQUE. 14 May, 1968 [17 May, 1967], No. 22910/68. Heading H3T. An inverting D.C. amplifier 1a, Fig. 3, has two Zener diodes 3a, 4a oppositely connected in series from output 9a to input 8a, whereby both positive and negative output voltages (Es, Fig. 2, not shown) are limited to narrow zones (11a, 11b) on the voltage output-current input characteristic, and has an odd number of inputs, for example three, 12a, 13a, 14a. The amplifier may perform NOR, NAND, and majority logic functions, according to whether the input voltage at 13a is fixed positive +U, fixed negative - U, or a free signal, respectively. Two such amplifiers Ia, 1b are connected to give a bi-stable circuit, which, as shown with + U at 13a and + U at 13b performs the function S=(C+S).#D, where D is an inhibit input. Faults in the amplifier, in the Zener feedback, in a preceding stage or in an interstage coupling are detected by departures of the output voltage from the narrow zones 11a, 11b. For example, the output voltage may reach the supply voltage (A) or the amplifier saturation voltage (V), or may have a value between the two zones, and such departures are detected by connecting at 9a a voltmeter, a moving spot galvanometer with a photo-cell having shaded areas corresponding to zones 11a, 11b and controlling a relay, or a numerical calculator. Alternatively, the voltage between two successive amplifiers is measured, a fault being indicated by this voltage being greater than the width of a zone (2#). Zero voltage means a loss of one input (there then being an even number of inputs left) in the condition where the remaining inputs are halfpositive and half negative. If this condition does not prevail, the loss of one input may be tested for, by applying a known voltage to an extra, test, input when the other inputs are known, so that zero output is expected if no fault is present. In an application, the input signals are received from an input circuit consisting (Fig. 5, not shown) of a similarly voltage limited amplifier (1c) deriving its input from a voltage source (19, 20) which may be a thermocouple, or a liquid-level measuring float-actuated potentiometer or a piezo-electric crystal, the circuit thus indicating when a given level of one of the non- electric variables is reached. The threshold is set by an adjustable voltage source (21).

Title: Improvements relating to electric arc lamps
IPC: H05B31/30
Filed: 1934-08-13
Abstract: 444,241. Arc lamps. STAHN, A., 4, Hohenzollernstrasse, Hanover, Germany. Aug. 13,1934, No. 23331. Convention date, Aug. 19, 1933. [Class 39 (i)] In a manually controlled electric arc lamp having inclined pivoted electrodes y, the electrodes are coupled by mechanism, e.g. a disc f and a pawl i in such a manner that when this pawl is actuated and then released, the ends of the electrodes first contact with each other and thereupon will be spaced apart a predetermined distance. The pawl comprises fixed and pivoted jaws h, i in a vertically slidable frame k arranged to grip the disc. On depressing the button o actuating the movable jaw i, the disc is released and the electrodes are brought together by the action of the spring g and the links d connecting the disc with the electrode holders b. The pressure applied to the button o also causes the frame k to move downwards so that when the button is released the jaws grip the disc again and the upward movement of the frame due to the springs p rotates the disc to space the electrodes apart. The spacing of the electrodes is determined by the adjustment of a stop r for the frame k. In a modification, two adjacent discs controlling two pairs of electrodes are frictionally coupled when the button o is depressed. The movement of the electrodes may be retarded by a pneumatic brake co-operating with the frame k.

Filed: 1945-09-12
Abstract: 599,031. Controlling several motors; controllers. REYROLLE & CO., Ltd., A., ROBERTSON, A. T., and HANSON, E. R. Sept. 12, 1945, No. 23524. [Class 38(iii)] [Also in Group XXXV] In an electric multi-screw ship propulsion system of the kind comprising two generators normally supplying different propeller motors and wherein means are provided whereby, in an emergency, all the motors may be driven from either generator, a three-position selector member is provided in one position of which normal connections are established, whilst in each of the other positions one generator is selected to supply all motors and the connection of the other generator to any motor prevented. In the twin screw system shown, in which the suffices s and p refer, respectively, to starboard and port equipments, the screws 10 are driven by motors 11 supplied from turbo - alternators 12, 13 over reversing switches 21 and sequence controllers 22. The last may be arranged in accordance with Specifications 578,099 and 589,749 and control the connections of the motor and alternator fields to a D.C. supply 16, as well as the turbine throttle 28 and the fields 18 of boosters 17 for the alternator fields. An emergency booster 19 may be substituted for either machine 17. A three-position selector 30, controlling a switch 29 allows, in its normal position, the motors to be supplied separately, but when moved to either of the other positions connects the motors in parallel for running from one generator. By an elaborate system of mechanical interlocks the selector and reversing switches may be moved only when the sequence controllers are in the " off " position and, when only one generator is selected, the sequence controller of the unselected machine is locked in its " off " position and the interlocks normally associated with that controller transferred to the other. The booster selector switch 64 is also interlocked with the sequence controllers to allow changeover of boosters only for a generator of which the associated controller is in its " off " position.

Abstract: 1,043,531. Drilling. H. HOBHOUSE. Oct. 1, 1962 [July 1, 1961], No. 23831/61. Heading B3C. A drilling machine comprises a hydraulic motor 6 for rotating a drill, the exhaust fluid being supplied to a ram 12 to feed the drill and means 9 for reversing the effect of the exhaust fluid if the torque on the motor exceeds a predetermined amount. When excessive torque operates the valve 9, the drill is withdrawn until a switch 13 is operated which causes drill feed to be resumed. Pressure is indicated by a gauge 15. In a modification, increased torque first causes a relief pressure to be supplied through a valve 47, Fig. 2A (not shown), but a further increase causes valve 9 to be reversed by actuation of a pressure switch 53 and to withdraw the drill. As the feed pressure drops, a switch 55A is released so that when switches 57, 57A are actuated by a plate 56, a relief valve 58 is opened, the valve 9 is reversed and the drill is advanced at rapid speed. When the switch 55A is again actuated, the valve 58 is closed and normal feed continues under the control of a throttle valve 48. Several bench or hand drills can be operated simultaneously.
