Patent GB-756234-A (GB)
Title: Improvements in electronic accumulators
IPC: H03K21/00
Filed: 1954-03-17
Abstract: 756,234. Digital electric calculating-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 17, 1954 [March 20, 1953], No. 7752/54. Class 106 (1). A decimal accumulator is characterized by the absence of any carry storage devices, the input pulses being sufficiently spaced in time to permit any carry necessary to occur immediately after the arrival of the pulse necessitating the carry, and before the arrival of the next pulse to be counted. A pulse to be counted, which may arrive on any of a number of parallel denominational channels is fed via a pulse-shaping triode 16 to the transfer electrodes T0-T9 of a multicathode tube G, described in Specification 734,903, and its trailing edge causes the glow, previously established between one of the digitelectrodes D0, D1-D9 and the anode A, to step to the next digit electrode. The arrival of the glow on the D0 electrode causes a rise in potential on a lead 23, which rise causes a negative carry-pulse to be passed from a carry tube 27, via a lead 32, direct to the transfer electrodes of the next higher denomination. A number may be subtracted from the number in the accumulator by first applying a complement pulse to the complement electrodes C0-C9, which causes the number in the accumulator to be replaced by its nines complement, then adding the number that has to be subtracted, and finally applying a further complement pulse. Read out is accomplished by suppressing interdenominational carry and applying ten input pulses to each tube, the differentially timed changes in potential on leads 33 then being representative of the number in the accumulator. The accumulator is initially zeroized by a switch 21. Specification 735,750 also is referred to.
Patent GB-817984-A (GB)
Title: Improvements in or relating to electrical control circuit arrangements for operationfrom an alternating-current supply
Inventor: WILLIAMS CHARLES EDINGTON
IPC: H05B39/08
Filed: 1957-03-08
Abstract: 817,984. Control systems for consumption apparatus. GENERAL ELECTRIC CO. Ltd. Jan. 30, 1958 [March 8, 1957], No. 7801/57. Class 38 (4). Relates to a system in which terminals 1, 2 are supplied with alternating current, and output terminals 3, 4 are connected to a load which may be a number of lamps for stage lighting in a theatre. Thyratrons 5, 6 are connected in parallel with each other in reverse senses between the terminals 1, 3, and are provided with trigger circuits 7, 8, each of which provides a constant negative bias voltage upon which is superimposed a voltage of peaked waveform and of adjustable phase. If the thyratron 5 has a smaller conduction-time than thyratron 6, for example, a direct component of voltage is developed between the terminals 3, 4 and a flicker at the supply frequency is introduced into the light from the lamps. However, capacitor 9 is charged to introduce into the trigger circuit 7 a voltage which reduces the resultant negative bias of the valve 5. The firing-period of the thyratron 5 is thus increased, so reducing the direct-voltage component between the output terminals. In addition, a capacitor 11 acquires a charge which increases the negative bias voltage for the valve 6, so further tending to equalize the firing-periods of the two thyratrons. The reverse effect takes place if the valve 5 has initially the longer firing-period. In a dimming circuit for a number of electric lamps, the control of brightness may be effected by variation of the trigger voltages applied to the control electrodes of the thyratrons. An adjustable potentiometer in one of the trigger circuits provides a pre-set control for initially reducing flicker to a minimum, Fig. 5 (not shown).

Title: Aeroplane brakes and their controls
IPC: B64C25/44
Filed: 1934-03-14
Abstract: 430,842. Aircraft wheel-braking systems. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, GOODYEAR, E. F., c/o Dunlop Rubber Co.,Foleshill, Coventry, WRIGHT, J., and TREVASKIS, H., Fort Dunlop, Birmingham. March 14, 1934, No. 8037. Addition to 397,897. [Class 4] An aircraft brake-control system comprises a number of valves actuated simultaneously by converging links pivoted to a pair of co-axial and spaced spindles constituting a common actuating link displaceable symmetrically or unsymmetrically relative to the axes of the valves along rotatable guideways by a flexible connection extending between the spaced spindles and guideways. The valves controlling the brakes are actuated by pairs of links 35, 36 and 37, 38 pressed together by clips 39 and mounted on spaced co-axial spindles 33, 34 which slide in slots 37 in rotatable guideways 23. The guideways are secured to a member 19 mounted in bearings in a casing 14 and rotated by an arm 20 connected by a link 11 to the rudder pedal (not shown). The inner ends of the spindles 33, 34 are mounted in a member 26 slidable between the guides 23 and blocks 25 to which the guides 23 are secured and carrying a shaft 28 connected by a flexible link or chain 29 and connecting members 30, 31 to a Bowden cable 8 operated by a finger lever on the main control (not shown). A stud 59 on the spindle 33 is engaged by the end of a coiled spring 56 arranged so that only side pressure is exerted during the initial movement of the spindles 33, 34, but increasing downward pressure is exerted when the spindles are returning downwardly to their inoperative position after release of the finger lever. On movement of the associated convergent links a cup 42, slidable in the associated valve casing compresses a spring 44, and outlet valve 47 is brought against its seat on a two part member 45 of which further movement is transmitted to the spindle 51 of an inlet valve 52 which permits compressed air to flow from a pipe line 6 to a chamber 48 and a pipe 2 leading to the associated brake mechanism. The load at the finger control is reduced during the building up of pressure in the chamber 48 by providing a conical surface 54 on which a diaphragm 49 mounted in the member 45 is deformed when the latter is moved backwardly. When the finger lever is released, the back pressure displaces the member 45 unseating the stop valve 47 which permits exhaust to atmosphere through the passage 46.

Filed: 1953-03-24
Abstract: 753,467. Automatic control systems. BOART PRODUCTS, SOUTH AFRICA, Ltd. March 24, 1953 [Sept. 18, 1952], No. 8139/53. Class 38 (4). [Also in Group XXXVI] In a process for electrolytically shaping a workpiece wherein a direct current is passed between the workpiece and an electrode, the voltage is controlled below that at which arcing occurs, by means of a shunt resistor 96 in one of the supply lines 94, a signal being generated in the resistor 96 due to an alternating current component arising when sparking or arcing occurs. The signal is fed to a transformer 98 and then amplified by a triode 100, the output of which is connected through a cathode follower tube 102 to a high pass filter. The filtered signal is then passed through a transformer 112, a rectifier 114, a condenser 116 and fed from a potentiometer 118 to the control grid of a pentode 120. The output of pentode 120 is connected to control windings 85 which augment the flux produced by bias windings 86 which saturate to greater or less degree saturable iron core reactance coils 84 in the supply lines of a three-phase supply. The voltage of the supply, which is rectified, to the electrode and workpiece, thus being reduced to cause arcing to cease. Specification 753,466, [Group XXXVI], is referred to.

Abstract: 496,447. Typewriters. TRIUMPH WERKE NURNBERG AKT.-GES. March 17, 1938, No. 8291. Convention date, May 27, 1937. [Class 100 (iv)] Letter - spacing mechanism.-For silencing the escapement during carriage-return, the loose dog is arranged to drop out of the path of the escapement-wheel when carriage-return is initiated, and a stop, operated by frictionmeans in connection with the escapementwheel, is provided for re-engaging the loose dog at the end of the carriage-returning movement. In the mechanism shown in Figs. 4 and 6, a rocker 1 is provided with a fast dog 12, and a loose dog 6 which is pivoted at 7 to a support 5 pivoted on a pin 4 on the rocker. The support 5 plays between stops 13, 14 on the rocker and is provided with an eccentric stop 9 and a silent stop 8, consisting of metal plates, for the dog 6. Another stop 22 for the dog 6 is adjustably mounted on a bellcrank 21 which is pivoted at 20 to the framework and is connected by a link 25a to an arm 27a on a friction-disc 28 engaging the escapement-wheel 36. The arm 27a has pinconnection 29 with a friction-cup 31 engaging the escapement-wheel. The friction-disc and friction-cup are pressed by springs 34, 35, the spring 35 being mounted in a cap 33. Normally the dog 6 engages the escapement-wheel and abuts on the stop 8, and the support 5 abuts on the stop 13. On depression of a key, the dog 12 engages the escapement-wheel, the support 5 is moved by a spring 15 into contact with the stop 14, and the dog 6 is rocked into contact with the stop 22 by gravity, aided, in some cases by a spring 10. On release of the key, the dogs 12 and 6 disengage and engage the escapement-wheel, and letter-spacing occurs. When the carriage is returned, the arm 27a is raised by the friction-members 28, 31, movement of the arm being limited by a lug 24 on the link 25a, and the stop 22 is retracted slightly. Thereupon, the dog 6 drops on to the stop 9 and is then out of the path of the escapementwheel teeth so that carriage-return can be effected silently. At the end of the returnmovement, the spring drum moves the carriage slightly forwards, the friction-members 28, 31 depress the arm 27a, the movement being limited by a lug 26 thereon, and the stop 22 restores the dog 6 to normal position. Carriage - releasing arrangements.-The pivot 4 of the loose-dog support 5 is moved axially, in opposition to a spring 17, to disengage the loose dog 6 from the escapement-wheel 36 for carriage-release.
