Title: Electric pulse circuits
IPC: H03K5/15
Filed: 1954-10-15
Abstract: 756,415. Condenser arrangements. STANDARD TELEPHONES & CABLES, Ltd. Oct. 15, 1954 [Oct. 19, 1953], No. 29749/54. Class 38 (4). [Also in Group XL (c)] A charge is transferred successively from one capacitor to the next in a chain via switching means which are successively closed to transfer the charge and then opened, each switching means being serially connected with an E.M.F. of such value that a constant value of charge is transferred along the chain. Fig. 1 shows a ring circuit in which capacitors C1, C2... Cn are equal in value and in which initially capacitor C1 is charged from a D.C. source via impedance Z and switches I and S1 the values of the E.M.F's el, e2 ... en are such that when a switch such as S2 is closed and then opened the charge on capacitor C1 is transferred without loss to C2 and so on around the closed ring. The switches S1, S2 ... Sn may be closed sequentially by applying driving pulses to operate the switches via gates which are opened only when the preceding capacitor on the ring is charged. The circuit may function as a pulse generator the pulses being taken from across the successive capacitors. The capacitors may be charged by pulses from sources E1, E2 ... En applied successively and periodically across the capacitors. The circuit may function as a corrector of the distortion which would otherwise occur due to pulses from sources E1, E2 ... En such as those issuing from a pulse distributer being applied across .capacitive loads C1, C2 ... Cn. The pulses across the loads have substantially vertical leading and trailing edges. In a modification shown in Fig. 2, the charge across the capacitors C11, C12 ... C1n is maintained of equal value on transference around the chain by the addition of charges across auxiliary capacitors C21, C22 ... C2n which are charged from a D.C. source via resistors Ral, Ra2 ... Ran. Fig. 3 shows the application of two ring switching circuits T11 ... T14 and T21 ... T24 as pulse shapers for the pulses from two distributers (not shown) having outputs P11 .. P14 and P21 ... P24 which trigger the respective switches and outputs P<SP>1</SP>11... P<SP>1</SP>14 and P<SP>1</SP>21 ... P<SP>1</SP>24 which are applied directly across the loads C1 ... C4. When a switching means such as T11 is defective it is automatically replaced by the corresponding switch T21 of the reserve ring or vice versa. If thyratrons are used as the switches they may be replaced if faulty under the control of relays in their anode circuits, Fig. 10 (not shown). Specification 752,843, [Group XXXIX], is referred to.

Title: Control method and equipment for charging ready-mixed concrete additives batchwise
IPC: B28C7/04
Filed: 1974-07-04
Abstract: 1480395 Automatic control systems JAPANESE NATIONAL RAILWAYS KAO SOAP CO Ltd and KAYABAKOGYO KK 4 July 1974 [12 July 1973] 29788/74 Heading G3R Additives are introduced into ready mixed concrete for a predetermined time if the concrete slump, as measured using the mixer torque, reaches a preset value. Following the introduction of additives, and after a further interval, the additive control system is reset so that further additive may be introduced into the concrete if necessary. In the embodiment, the slump is measured by sensing the torque on a concrete mixer, either directly or using the pressure of a hydraulic mixer drive. If the torque exceeds a pre-set value i.e. the slump falls below a certain value, a timer is energized. An additive feed motor is turned on for a given time by the timer using a switching transistor & l.e.d. - phototransistor link. The timer continues to operate after the motor is switched off, and resets the system so that further additive may be introduced if the slump again falls below the pre-set value. The system thus keeps the slump above this pre-set value. The control system, including the oscillator timer, is supplied from a series transistor voltage regulator.

Title: Improvements in or relating to electrical oscillation generators
IPC: H03B5/22
Filed: 1949-11-22
Abstract: 666,464. Valve generating circuits; frequency modulation. GENERAL ELECTRIC CO., Ltd., and CORMACK, A. Oct. 25, 1950 [Nov. 22, 1949], No. 29957/49. Classes 40 (v) and 40 (vi). A phase shift oscillator of the type comprising a first valve arranged as a resistance capacity coupled amplifier connected in a loop with at least three cathode follower stages has its frequency varied or modulated by varying or modulating the anode load impedance of the first valve. As shown, a resistance capacity coupled amplifier 1 is followed by four cathode followers 2, 3, 4, 5, the output from the final cathode being fed back to the grid of amplifier 1. The loop will oscillate at the frequency at which the phase change produced by each cathode follower as a result of the interelectrode and stray capacitances is 45 degrees. The output is derived from the cathode of stage 2 and is fed to an output stage 23. A further cathode follower 26 is connected across the anode load 10 and owing to the grid cathode capacitance of the valve its output impedance is inductive and may be varied by varying the grid bias. In the circuit described a variation of frequency between 40 and 100 mc/s. may be obtained without changing the output amplitude by simultaneously varying the grid bias of the cathode followers 2-5 and between 100 and 150 mc/s. by varying the grid bias on the cathode follower 26, a continuous variation throughout the two ranges being obtained by means of a potentiometer 54. With the slider at its lowest point all the cathode followers are heavily biased but as it is raised an increasing positive voltage is applied through resistor 43 to the control grids of stages 2-5. This continues until the positive bias applied from a potentiometer 46, 47 to the cathode of a diode 38 is overcome when the diode conducts preventing further rise. At this point however the negative bias applied from a terminal 52 to a further diode 40 is also overcome and this diode conducts and the bias on stage 26 is thereafter reduced below the cut-off value applied from terminal 52. The voltage obtained from the potentiometer 54 may be replaced by a modulation voltage and chokes may be included in the filament leads for the cathode followers 3-5 to reduce the cathode-earth capacitance and thus increase the maximum oscillation frequency.

Filed: 1956-10-02
Abstract: 831,799. Ammunition fuzes. MARTIN, A. Oct. 2, 1956 [Oct. 4, 1955(2); Nov. 15, 1955], No. 30045/56. Class 9(1) [Also in Group XL(b)] Within a casing there is an objective which produces in a plane fixed with respect to the casing a sharp real image of everything within its field, and photoelectric devices responsive to a sharp difference of illumination between two areas thereon but unresponsive to a blurred image spread over two areas. In a proximity fuze, Fig. 10, light from a bulb 47 is directed towards a target aircraft whence it is reflected back through the objective 2 to form, when the target is at the correct explosion distance, a sharp image on an annular photo-cell 51 (the sharpness cell) responsive only to the wavelength of the light. Unbalance between the signal produced by the sharp image on this cell and the signal from adjacent image free cells 52, 53 (the balancing cells) is amplified by transistors 8, 9, 10 to operate a detonator 7. If no light is reflected from the target or if the target is out of range so as to produce a blurred image over both the sharpness and balancing cells the cell outputs balance and nothing occurs. The light source may be in the tail of the projectile or may be replaced by the light contrast of the target aircraft against the sky. The device may control steering rockets or may be used as a fire control mechanism. The cells may be connected to react when the image is produced on any of them. In a revolving projectile two cells may scan an annular image plane (Fig. 6, not shown). Barrier layer and germanium junction cells are referred to.

Title: Improvements in or relating to products obtained by the treatment of cashew nut shell oil, and to methods of obtaining such products
Filed: 1926-11-27
Abstract: 262,134. Harvey, M. T. Nov. 28, 1925, [Convention date]. Fats and fatty oils. - Reaction products, varying from jelly-like materials to hard rubber-like products, are formed from the oil found in the shell surrounding the kernel of the cashew nut and glycerine or homologues of glycerine. Reaction may be produced by heat or by acids such as sulphuric acid or by ammonia. The ingredients may be heated together, or one or both of them may be heated before mixing. The products may be vulcanized. In examples, (1) equal parts of cashew nut shell oil and glycerine are refluxed with an air condenser for about three hours, at a temperature beginning a 245‹ C. and increasing. The jelly obtained, if heated at 104' C. for 2-3 hours becomes hard and resilient. (2) 3 parts of the oil and one part of glycerine, air-refluxed at 245' C. for fifteen minutes, results in a material which if spread in a thin film dries quickly to a tough sticky layer. (3) 5 parts of the oil and 2 parts of glycerine, refluxed at 245‹ C. for thirty minutes, allowed to stand for 24 hours, and thickened by beating at 104' C., produces a rubber-like material, which on heating with varying quantities of sulphur produces materials of varying hardness. Sulphur chloride produces material similar to granular or powdered hard rubber. The vulcanizer may be mixed with the oil and glycerine initially. The reaction products, including the vulcanized products, are soluble in solvents such as carbon disulphide, naphtha, phenol, benzine, &c., and if such solution be spread on a surface and dried at 100‹ C. a tough elastic film is produced.
