Abstract: 585,619. Electromagnetic interrupters. VENNER TIME SWITCHES, Ltd., and HORGAN, W. F. Sept. 29, 1944, No. 18723. [Class 38 (v)] [Also in Group XXXV] High tension impulse apparatus for electrifying wire-fencing comprises a transformer which is energized intermittently by a make-and-break switch which initiates the functioning of an overriding time' control, and a panel carrying a battery condition indicator and battery testing and output controlling switches; each of the parts, transformer, switch, control and panel being separately mounted on a base. On the base 1 are mounted a transformer 4 by angle supports 5 at the ends; an impulsing switch comprising a winding 9 on angle supports 7, and an armature 10 pivoted at 7a and carrying a contact 12 on a metal strip 13 from which the armature is insulated; and a time-control unit comprising a die-cast aluminium disc 17 biassed by a spiral spring 25 and mounted in bearings described more fully in Specification 585,618 in an insulating carrier 18 formed in two equal parts 18b and secured to the base 1 by screws 32. One end of spring 25 is fixed to the disc and the other to a pin 27 adjustable in an arcuate slot 18a. Pillars 34 on base 1 carry a panel 35 on which are mounted parts as shown and labelled in Fig. 1, which also shows the base 1 mounted in a case 2. When base 1 is inserted in case 2, a bolt 57 and a pillar 60 engage spring contacts permanently mounted in the case 2 in connection with battery leads in cable 80, and a spring 73 contacts the end 45a of a fence-lead terminal 45. When fence-switch 39 is put on current flows from a battery (not shown) through the battery leads and a circuit including the following parts, switch 39, fuse 37a, pm 27, spring 25, disc 17, contact 19 which is mounted directly on the wheel 17, contact 12, armature biassing spring 15 and cable 48a in parallel, coil 9 of the electromagnetic switch, and the transformer primary. Coil 9 now being energized, armature 10 is pulled downwards until a leaf spring 13 engages a stop 14 and co-operation of contacts 12 and 18 give a clockwise impulse to wheel 17, which moves to separate the contacts and is brought back by spring 25 when it again receives an impulse and is thus kept in oscillation. Upon each closing and opening of contacts 12, 19 an electric impulse through the transformer primary generates a high tension impulse in the two secondary windings bought out to leads 63, 64. According as the weather is wet or dry one of these leads is connected by a bridge 44 to the fence-lead terminal 45 through lead 65 and spring 73. A condenser 67 is connected across the switch contact. The battery condition indicator 36 is connected across the battery leads upon depression of push-button 40. Specification 585,617 also is referred to.

Abstract: 344,742. Carburetted water-gas. HUMPHREYS & GLASGOW, Ltd., Humglas House, Carlisle Place, London.-(Assignees of Perry, J. A. ; Broad Street, Phila. delphia, U.S.A.) June 19, 1930, No. 18748. Convention date, July 27, 1929. [Class 55 (i).] In the manufacture of mixed oil gas and water gas in apparatus comprising two generators and a superheater, after blasting both fuel beds, oil is supplied above and steam below one fuel bed, and the mixture of water gas, oil gas and undecomposed steam is passed in part through the other fuel bed and in part through the superheater. The apparatus comprises two generators 1, 2, and a superheater 19, air blast pipes 7, 8, and steam pipes 9, 10 at the bottom of the generators, secondary air pipes 11, 12 oil supply pipes 16, 17, and steam pipes 13, 14, 15, a conduit 18 connecting the gas spaces of the generators. The fuel beds are blasted simultaneously, the blast gases being burned to heat the spaces 4, 6 and passed through the superheater. Oil is then admitted to generator 2, for instance, and steam through pipe 10, the oil being vaporized and coke deposited on the fuel bed, and the mixed oil gas and water gas are passed partly through the superheater to the outlet 26, and partly through the fuel bed in generator 1 to the outlet 33, and storage where they may be mixed with the gases from the superheater. This process is then reversed, steam being supplied to generator 1 and the gases passed partly through generator 2 and partly through the superheater, the coke residues from cracking the oil being deposited in fuel bed 5. Steam from pipe 15 is then passed through the superheater 19 and through both fuel beds to generate water gas from the carbon deposited from the oil. In a modified method steam is supplied below one fuel bed on to which oil is sprayed and some steam is supplied below the other, the mixed gases passing through the superheater; the steam supply is then increased and the water gas passed through the generator to which oil was supplied, this process being then reversed.

Title: Improvements in or relating to pulse controlled oscillator arrangements
Inventor: MORTLEY WILFRED SINDEN
IPC: H03L7/24
Filed: 1953-04-02
Abstract: 724,282. Valve generating circuits, pulse radar. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. April 2, 1953 [July 24, 1952], No. 18810/52. Classes 40 (6) and 40 (7). In an arrangement for producing oscillations the phase of which is controlled by periodic pulses of oscillation the pulses cause a first oscillator to be switched off and a second oscillator to be started in the correct phase, the first oscillator then being restarted in the correct phase by the second oscillator which is thereafter switched off. In the so-called radar " coherent " oscillator circuit shown, the occurrence of an R.F. synchronizing pulse at the grid of valve V1 causes the second valve V2R of a " flip-flop " circuit to be cut off. The pulse at the anode of V2R renders valve V3 of a cathode feedback oscillator circuit conductive and the.pulse at the cathode starts oscillation in the resonant circuit of the oscillator in the correct phase. The fall of the anode voltage of the oscillator valve V3 renders inoperative the valve V4 of a more stable oscillator, comprising valve V4 and circuit T.C. so that the existing oscillations in the circuit die out. At the same time the oscillatory output from the anode of valve V3 is fed to the left-hand end of the circuit T.C. to cause oscillation in the correct phase to commence. After a brief period the " flip-flop " returns to its original condition and so switches off V3 which thus switches on V4 causing oscillations to be sustained in the circuit T.C. An output is taken from a capacitive tap on this circuit to an amplifier valve V5.

Abstract: 1,125,847. Common correction circuit. PHOTO ELECTRONICS CORP. 2 May, 1966 [4 May, 1965; 10 Dec., 1965], No. 19168/66. Heading G4G. [Also in Division H4] A non-linear circuit, which is used as a gamma correction circuit in a local viewing television system for examining colour negatives (see Division H4), comprises an amplifier including a transistor 244 which has in the emitter circuit a number of biased diodes 264, 264A, 264B which become conductive at predetermined signal levels to introduce resistors 266, 266A and 266B in shunt with the main emitter circuit 246, 248, 256 to vary the amplifier gain, whereby the input-output characteristic of the circuit, Fig. 5 (not shown), comprises a "curve" formed of a number of linear sections of different slope. The slopes of the sections are determined by adjustment of resistors 256, 266, 266A, 266B, whilst the signal levels at which the slope changes are determined by adjustment of the diode biases. The bias values are determined by resistors 274, 274A, 274B which are connected to the diode circuits via transistor pairs 270, 272; 270A, 272A; 270B, 272B which function as low impedance current sources so that the bias adjustments do not modify the slope adjustments. One or more of the diodes may be reversed so that the changes of slope are not all of the same sign. A limiter 276 connected in the collector circuit reduces the slope to zero at the peak (picture white) level of the input signal. Feedback from the emitter circuit is applied via lead 250 to one input of an input differential amplifier 242.
