Title: Improvements in and relating to overload protective equipment
IPC: H01F27/40
Filed: 1964-02-28
Abstract: 1,016,126. Protective arrangements. BROWN, BOVERI & CO. Ltd. Feb. 28, 1964 [March 1, 1963], No. 8345/64. Heading H2K. An overload protective arrangement includes means for indicating the period of time a circuit or apparatus may continue in operation under overload before a predetermined maximum temperature limit is reached. In Fig. 1, thermocouples 3, 4 are arranged in the oil of a protected transformer 1, the thermocouple 4 being associated with heat insulation and a heater energized in accordance with the transformer load current so that the output of the thermocouple 4 represents the temperature of the transformer windings whilst that of the thermocouple 3 represents the temperature of the oil. The outputs of the thermocouples 3, 4, after amplification at 7, and the output of a current transformer 2 are applied to a digital computer 8, which is rendered operative on the closing of an overcurrent relay 6 and is programmed to compute the period of time which will elapse before the transformer windings reach their maximum permissible temperature. A relay 9 trips a circuit-breaker (not shown) when this temperature is reached. In Fig. 2 the relevant temperatures are simulated by an RC circuit arrangement including resistors 31, 46, 47 and capacitors 44, 45 having time constants corresponding to those of the protected circuit 1. A second RC circuit arrangement including resistors 32, 16, 17 and capacitors 18, 19 is normally connected by contacts 22, 23 to the first circuit arrangement so that the voltage U 4  across the capacitor 18 is the same as that across the capacitor 44. When an overload condition occurs, a device 21, automatically or manually controlled, opens contacts 22, 23 and closes contacts 28 to connect the second RC circuit arrangement directly to the amplified and rectified output of the current transformer 4 supplying the first RC circuit. The capacitors 18, 19 have smaller capacities than the capacitors 44, 45 and so charge quickly. The time taken for the capacitor 18 to charge to a voltage corresponding to the permissible maximum temperature is determined by a timing device 25 and is used to indicate the time remaining before capacitor 44 becomes sufficiently charged to cause the tripping of a circuit-breaker 13. In a further arrangement, Fig. 3 (not shown), thermocouples are periodically connected to a computer, which from the rise in output, i.e. temperature, occurring between successive connections, determines the time which will elapse before the maximum temperature is reached.

Title: Control circuit for cathode ray tube
IPC: H04N3/20
Filed: 1955-03-25
Abstract: 771,509. Cathode-ray tube circuits. STANDARD TELEPHONES & CABLES, Ltd. March 25, 1955 [April 2, 1954], No. 8855/55. Class 40(7) A control circuit contains a valve which is rendered conducting during the return trace of the deflection signals of a C.R.T. and also during the absence of such signals, and non-conducting during the sweep portions of the signals, thereby reducing the potential of the accelerating electrode of the C.R.T. and cut out the visible trace on the fluorescent screen of the tube. The anode of the output tube VO of a frame sweep oscillator is connected to the primary T1 of the transformer feeding the deflection plates, and to the grid of the detector V1 via a condenser C, and resistor R1. The grid detector circuit of tube V1 comprises a resistance R3 shunted by a condenser C2. The anode of tube V1 is connected to the first anode A1 of the C.R.T. The condenser C2 is charged negatively by the 'positive pulses of the frame sweep and cannot discharge owing to the high value of R3. The grid of V1 is therefore polarized negatively and the tube is only rendered conductive at the apex of the pulse, i.e. during the return trace. When tube V1 is conductive, the voltage drop in Ra lowers the potential of the first anode Al of the C.R.T., and decreases the acceleration of the beam. This occurs therefore when (a) the beam is on the return trace of the frame sweep and (b) the frame sweep oscillator is inoperative, the tube V1 in this case being permanently conductive. The control is applicable to the line sweep, e.g. in cathode-ray oscillographs.

Title: Radiation translation by rotary transducer scanning
IPC: G03H3/00
Filed: 1973-03-18
Abstract: 1446022 Ultrasonic imaging system HOLOTRON CORP 18 March 1973 9102/73 Heading H4D An ultrasonic scanning system for investigating an object includes an ultrasonic source, a point-like receiver, and an acoustic lens for directing ultrasonic waves from the object on to the receiver. The source and/or receiver is scanned in a curved path about an axis of rotation and either the axis is moved relative to the object or the radial distance of the source or receiver from the axis is changed. In the Fig. 1 holographic system reflected ultrasonic waves from an object 11 in a liquid container 19 are detected by a receiver transducer 17 on a rotating disc 21 moved at right angles to the axis of rotation. The transducer output is mixed at 23 with an electrical coherent reference signal and the resulting hologram signal modulates the brightness of either a CRT beam or a lamp 31. The CRT beam or lamp is scanned in synchronism with transducer 17 and is photographed to give a hologram which can be reconstructed by convergent laser light (Fig. 7, not shown). The rotating disc may carry one or more (in the latter case sequentially-used) transmitting and/or receiving receiving transducers instead of the single transducer shown, and may be moved parallel to (instead of at right angles to) the axis of rotation (Figs. 2 to 6, not shown). Alternatively the transducers may be mounted along a radius of the disc, on a slide which is moved radially by a cam at a selectable rate, to give a spiral scan providing selectable resolution (Fig. 9, not shown). In the Fig. 10 embodiment, for direct imaging underwater, ultrasonic energy from transmitters 193, 195 is reflected by an object field on to an acoustic lens 197 and hence directed to a scanning plane in which are arranged radially-aligned and movable receivers 185 on a rotating disc 181. The receiver outputs are displayed on a synchronously scanned CRT 191. The lens comprises a liquid-filled chamber with two flexible films as its boundary, and its focus is variable by moving the fluid to or from a supply 199. Housing 189 contains a coupling fluid. Alternatively the lens may comprise a chamber with one flexible film as its boundary, the disc 181, receivers 185 and coupling fluid being arranged within the chamber (Fig. 13, not shown). The invention is applicable also to systems in which ultrasonic energy is transmitted through, rather than reflected from, an object to be imaged.

Title: Improvements relating to lamp holders for tubular lamps

IPC: H01R33/08
Filed: 1959-03-17
Abstract: 874,811. Lamp caps and holders. CROMPTON PARKINSON Ltd. March 17, 1960 [March 17, 1959], No. 9242/59. Class 38 (1). A lamp-holder for a fluorescent tubular lamp having a bi-pin cap is provided with contact holes each of which is situated approximately at the centre of a D-shaped recess 5 which increases in depth from the edge to a maximum at the contact hole. The two recesses are separated by a diametrical ridge 6. When the pins 3 of a lamp are moved against the end face of the lamp-holder they will normally be out of register with the holes 4 and will engage the surface of the recesses 5. A turning action is thus produced on the lamp and the pins are brought into correct location preparatory to being pushed home. The main housing 11 of the holder carries a sliding part 12 having lugs 16 which engage in slots 17. Outward movement of the part 12 is limited by engagement of the lugs with a wire ring 18.
