Title: Improvements in or relating to electrical switching circuits which derive pulses from changes of state of a magnetic core
IPC: H03K19/16
Filed: 1954-06-22
Abstract: 760,437. Circuits for bi-stable magnetic devices. WESTERN ELECTRIC CO., Inc. June 22, 1954 [June 24, 1953], No. 18285/54. Class 40 (4). A magnetic core 10A having a plurality of input windings 16, a reset winding 13, an " advance " winding 14 and an output winding 15 is arranged as a " joint denial " circuit, i.e. it produces an output only when no input has been applied to any of the input windings 16. The core is initially magnetized clockwise by the reset winding 13. Then the inputs if any are applied and these magnetize the core anticlockwise. The advance pulse applied over winding 14 then also magnetizes the core anticlockwise. Thus, a big change in magnetization then occurs to produce an output pulse only if no input has been received. Such a circuit is thus seen to produce an output function f = x<SP>1</SP>y<SP>1</SP> (in the usual Bodlean notation), where n and y are the inputs and may clearly be extended to any number of such inputs. The Specification demonstrates that any switching function may be constructed by a suitable combination of such circuits with or without OR circuits. Application to a binary adder. Such a circuit requires a switching function f = xy<SP>1</SP> + x<SP>1</SP>y. In one embodiment this function is obtained in the form (x<SP>1</SP>y<SP>1</SP>)<SP>1</SP>. (xy)<SP>1</SP>. Accordingly two joint denial circuits 10A, 10B are fed with inputs x, y and n<SP>1</SP>, y<SP>1</SP> respectively and their outputs are combined in a further joint denial circuit 11. A cyclic pulse generator 24 provides information gating, resetting and advancement pulses at instants t1 ... t4 as shown in Fig. 2. At time t1 resetting pulses are applied to rings 10A, 10B. At time t2 the information from sources a ... d are fed to the respective inputs. At time t3 the advance windings 14 are pulsed and the outputs from windings 15 applied to the inputs of the circuit 11. At time t4 the advance winding 19 is pulsed to produce the required output from winding 21. The reset pulse for circuit 11 is made to last over periods t1 and t2. This arrangement eliminates spurious registrations on core 11 due to registrations on cores 10A, 10B. A resistance 41 minimizes the interaction of the application of the reset on circuit 11, during the application of an information pulse to circuit 10A. In this embodiment the polarity induced by energization of the advance winding 19 is given by the arrow 36. If instead the polarity is given by arrow 35 the circuit 11 then behaves as an OR circuit and the required binary addition may be effected by feeding the joint denial circuits 10A, 10B with x<SP>1</SP>, y and x, y<SP>1</SP> respectively.

Abstract: 1384786 Measuring mains impedance SIEMENS A G 20 April 1972 [24 April 1971] 18471/72 Heading G1U [Also in Division H2] Electrical apparatus such as an x-ray set comprises a resistor 4 connectible as a load across voltage supply terminals 20, a capacitor 9 for producing a control signal which represents a drop in the supply voltage when it is loaded by the resistor, the control signal also representing the internal resistance of the supply, and circuitry 2, 13-16 responsive to the control signal for automatically matching the apparatus to the internal resistance of the supply. The apparatus includes a high voltage generator 1 and an internal resistance matching circuit 2. Initially switches 11, 12, 19 are in their illustrated positions with the resistor 4 loading the supply. When a capacitor 5 is fully charged a time switch 10 changes over the switches 11, 19 to un-load the supply and the capacitor 9 therefore charges to a voltage equal to the difference between the loaded and un-loaded supply voltages, i.e. to a voltage proportional to the internal resistance of the supply. A time switch 17 then changes over the switch 12 to enable the voltage on the capacitor 9 to change the state of one of the Schmitt triggers 13-16 which supplies a signal to the matching circuit 2 to adapt the x-ray set to the internal resistance of the supply. A constant current circuit including a transistor may be connected between diodes 6, 7 to prevent variations in the un-loaded supply voltage affecting the internal resistance measurement.

Abstract: 530,492. Bridge &c. lighting fittings. GENERAL ELECTRIC CO., Ltd., BEGGS, S. S., and THOMAS, E. R. June 26, 1939, No. 18555. [Classes 75 (ii) and 75 (iv)] In a lighting fitting having a linear source of light and reflectors which direct substantially all the light to one side of a plane BC through the source in a manner such that the light distribution in all other planes through the source is substantially the same and such that a maximum of intensity is formed in these planes at an angle to the source, one at least of the reflectors, BAC, CE or BD as the case may be, takes the shape formed by the semi-revolution of a parabolic arc having its axis in the direction of maximum intensity about an axis BC through its focus, F, in the case of BAC, F 2  in the case of CE or BD, and one end of the linear source lies at or near the said focus and the opposite end inside or outside the axial cone (or plane) traced out by the axis, F,Y or F,X, of the parabolic arc accordingly as the reflector lies on the same or opposite side of the plane BC as that to which the light is directed. Rays reflected from the paraboloidal reflector are thus distributed beneath or mainly beneath the cone of rays of maximum intensity. In an extreme case the angle of the or each parabolic axis to the axis of revolution may be a right angle. Preferably each reflector is a parabolic half surface of revolution about the axis BC with the light source, such as a HPMV lamp, extending between the focus F, of reflector BAC and the common focus F. of reflectors CE and BD and with the axes F 2 Y, F,X parallel. Alternatively, Fig. 3, one of the reflectors, GH, may be spherical with its centre F 3  between the foci F 1 , F 2  of the reflectors AB, BD, and a part conical reflector JK may be arranged to direct upward rays downward. HG and AB may be spaced or continuous. A slightly diffusing glass with ribs parallel to the axis BC or a refractor which concentrates the light into particular vertical planes through BC may also be used with the reflectors. The fitting is particularly adapted for lighting streets and bridges, and for floodlighting.

Title: Improvements in and relating to apparatus for recording the consumption of commodities, such as gas
IPC: G01F15/07
Filed: 1948-07-08
Abstract: 668,828. Recording-apparatus. SMITH METERS, Ltd., CHARLES, A., and CHARLES, J. A. July 8, 1949 [July 8, 1948], No. 18559/48. Class 106 (iv). Apparatus for recording the consumption of gas comprises one or more strikers each acted on by a corresponding cam that is rotated at a speed dependent upon the rate of rotation of a metering spindle to produce a record on a timedriven record surface. The metering mechanism of the gas meter is coupled to a shaft 5, Fig. 1, through a stuffing box, and through worm 6 and worm wheel 8 drives a shaft 9 to which are fixed two cam discs 10, 11 with diametrically opposite cam recesses 12, Fig. 5, co-operating with bell-crank levers 13, 14 pivoted about an axis parallel to but below the shaft 9 and carrying heads 16 in which are screwed pins 17 with coned heads 18 which are caused to strike a record surface 31, which may bear time graduations, with a frequency depending on rate of consumption. Clockwork mechanism 22 drives a gear-wheel 24 which is frictionally. engaged with and drives through gears 27, 29 a spindle 20 carrying a spiked drum 19 which thus draws the record surface from a spool 32 and feeds it to a spool 33 at constant speed, the spools being held frictionally by spring washers 40 and clips 41 on bosses of gear-wheels 34 (not shown), and 35 both engaging a gear-wheel 38. To accommodate the varying diameters of the rolls on the spools the gear-wheel 35 is half the diameter of gear-wheel 34 (not shown) and slipping occurs. In order that the strikers may mark the record surface an ink ribbon 43 is drawn from a spool 44, which may be frictionally driven from an extended washer 51 with pins 55 for manual rewinding, to a spool 47 frictionally mounted on a spindle driven by worm and worm wheel from the cam-shaft 9. The ribbon is guided over the record surface 31 in the path of the strikers by superposed wire loops 46 held in a spindle 64, Fig. 3, which may be turned from operative position to inoperative position as determined by a plunger in a plate 65 entering one of two holes in the supporting framework. The apparatus may be closed by a casing having a window for observing the record and formed with key-holes to engage headed pins 68 and spaced eyelets for embracing a lug 69 for padlocking. Change-speed gearing may be introduced between the meter mechanism and camspindle to allow for adjustment to space the marks. Other forms of cam may be used so long as they release the strikers suddenly. Ribbon reversing mechanism may be included. The clockwork mechanism may be replaced by other time mechanism. The recording may be by punching, the drum or other support being formed with channels into which the punches may enter on perforating the paper, means being provided for immediate withdrawal of the punches.

Title: An electronic oscillator
IPC: H03B5/34
Filed: 1955-06-30
Abstract: 792,510. Crystal oscillator circuits. BENDIX AVIATION CORPORATION. June 30, 1955 [Aug. 6, 1954], No. 18980/55. Class 40 (6). An oscillator comprises a valve having its cathode connected to earth through a first parallel resonant circuit L2, C3 and to its grid through a second parallel resonant circuit L1, C1, C3, the grid also being connected to earth through a selected one CR of a number of crystals covering a frequency band. The first tuned circuit resonates below the lowest crystal frequency and is accordingly always capacitive and the second above the highest crystal frequency and accordingly is always inductive. It is explained that a phase shift of a little less than 90 degrees takes place at the cathode and that at the frequency of oscillation the crystal is reactive so that a phase shift of little over 90 degrees takes place due to the combination of the second resonant circuit and the crystal. Accordingly regenerative feedback occurs with all the crystals. The selected crystal may operate in a harmonic mode in which case the resonant frequencies of the first and second circuits are chosen to avoid operation in modes other than the desired one.
