Title: Improvements in or relating to electric stabilising circuits
Inventor: WENHAM DAVID GEORGE
IPC: H02M3/338
Filed: 1958-06-30
Abstract: 885,685. Automatic control systems for electricity supplies. GENERAL ELECTRIC CO. Ltd. June 4, 1959 [June 30, 1958], No. 20866/58. Class 38 (4). In an automatic control system a load is connected to the input or rectified output of an oscillator and a parameter of the power supplied to the load is stabilized by varying, through an amplifier, the emitter-collector impedance of a transistor connected between a direct-current source and the input of the oscillator. In an embodiment, an oscillator 2 having a rectified output is supplied via a transistorized stabilizing arrangement 1 from a source connected to terminals 12, 13. The oscillator 2 comprises bridgeconnected transistors 14-17 having emitterbase feedback applied from windings 20-23 of a transformer 19. The square-wave voltage across a secondary 30 is fed to output terminals 33, 36 via a bridge rectifier 31-34. The voltage across a winding 38, proportional to the output voltage, is rectified and smoothed by a diode 39 and a capacitor 40. The stabilizing arrangement comprises parallel-connected transistors 3, 4 the emitter-collector impedance of which is dependent on the collector current of a transistor 6 amplified by a transistor 7. The transistor 6 is energized by the voltage across the capacitor 40 and a feedback voltage is applied from a tapping on a potential divider comprising resistors 42-44. The emitter voltage is stabilized by a Zener diode 9 and resistor 8. It is stated that the feedback voltage may be derived from the output across terminals 35, 36 and that the load may be connected to the input to the oscillator 2, the feedback voltage being derived from across the load. The starting of the oscillator is facilitated by biasing resistors 28, 29 and a resistor 5 by-passes oscillator current when the transistors 3, 4 are cut-off.

Abstract: 780,658. Making carbonated liquids. LEECH, H. CAYZER-. July 21, 1954, No. 21249/54. Class 14 (1). [Also in Group XXI] A device primarily designed as a fire-extinguisher but capable of use for generating soda water or making fruit drinks is brought into use on the coming into contact of two liquids to generate carbon dioxide and comprises outer and inner containers for the liquids, normally separated by valve means, a dip tube extending into the lower region of the outer container for discharging the device through a nozzle at the upper end of the tube, and an aperture in the upper end of the outer container controlled by a valve member connected to the valve means so as to be closed when the valve means is open and open when it is closed. Thus the interior of the device is open to atmosphere when the valve means is closed and closed to atmosphere when the containers are in communication. Resilient means bias the valve means towards open position, and means are provided resisting the action of the resilient means until the device is to be used. The dip tube 5 comprises a handle portion 5a, a nozzle 6 closable by a cap or a plug 7, and a rubber extension 5b. The containers 1, 2 are separated by a frusto-conical soft rubber valve 8 fixed to the dip tube 5 by collars 9. A closure head is in the form of a nut 3 screwed over the neck 1c of the outer container 1, the inner container 2 being supported by a flange 2a on the neck. Within the nut 3 is a medium-hard rubber valve 4 engageable upwardly with the interior of the nut and closed by a collar 4a on the cube when the latter is moved upwardly to open the valve 8. The containers 1, 2 are provided with separate manually removable filler plugs 12, 13 respectively. The containers can easily be washed through with the valve 8 open, and when the valve is closed can be filled with water, and the requisite substances to form the solutions introduced in the form of pastes from collapsible metal tubes screwed into the filler plugs. The inner container may be charged with citric acid and the outer with sodium bicarbonate. The outer container may also be provided with a further opening to which can be screwed a cylinder of compressed carbon dioxide, which gas is led to an expansion chamber in the container and thence through a narrow tube and into the upper part of the container. The expansion of the gas has a refrigerating effect on the liquids and also adds to the pressure of ejection.

Abstract: 1,053,019. Ferrite attenuators and phaseshifters. SPERRY RAND CORPORATION. May 20, 1965 [May 25, 1964], No. 21335/65. Heading H1W. The propagation characteristics of a coaxial line ferrite device are varied by relative rotation of the conductors, one of which incorporates a permanent magnet. In the device shown, which may be a phase - shifter or an attenuator, two ferrite elements 21, 22 are mounted upon the diametral face of a member 20 of dielectric material (e.g. alumina) which occupies about half the space between inner and outer conductors 11, 12. The outer conductor 12 together with members 20, 21, 22 is rotatable about the (fixed) inner conductor 11 which incorporates a transverselymagnetized permanent magnet 25. Such rotation alters the strength and direction of the magnetic field through the ferrite elements. The outer conductor is encased in soft iron and provides a low-reluctance flux path. In a modification, the members 20, 21, 22 are fixed to the inner conductor and the (rotatable) outer conductor comprises two hemi-cylindrical portions, one of soft iron, the other of brass. The position of the soft iron hemi-cylinder relative to the ferrite elements determines the effective magnetic field. The devices may be either reciprocal or non-reciprocal in operation.
