Abstract: 1,135,161. Adding, multiplying circuits. BRITISH SCIENTIFIC INSTRUMENT RESEARCH ASSOCIATION. 21 April, 1967 [22 April, 1966], No. 17820/66. Heading G4G. [Also in Division G1] Subtraction, addition and multiplying circuits using operational amplifiers form part of a system for investigating photo-electrically geometrical properties of flat objects such as coins (see Division G1). Two identical subtraction circuits, Fig. 4A (not shown) utilize an operational amplifier (X1) having feedback resistors (R5, R6) determining the gain; balancing for zero offset by a variable resistor (RV1); variation of input signal amplitude ratio by another variable resistor (RV4); and high frequency gain reduction by feedback capacitors (CV1, CV2). Zero offset and high frequency gain reduction are provided in an amplifier circuit for summing four input signals, Fig. 4B (not shown), together with D.C. balancing. Three identical variable gain amplifiers are used of the type described with reference to Fig. 5 (not shown). Gain is variable between 1 and 5 by a feedback variable resistor (RV10) Bandwidth limitation is by feedback capacitors (C20 and C10). Output voltage limits are set by resistors (R26-R31) and saturation of the operational amplifier (X1) prevented by diodes (D2 and D3). A further diode (D1) prevents latch-up.

Abstract: 593,798. Radio direction-finding. AMALGAMATED WIRELESS (AUSTRALASIA), Ltd. Sept. 21, 1944, No. 18083. Convention date, Nov. 12, 1943. [Class 40 (v)] Relates to Adcock aerial systems suitable for use in goniometer or two -path D.F. systems in which the aerials are coupled to their associated feeders by cathode-follower stages. According to the invention, the amplification of the individual cathodefollowers is remotely controlled to facilitate balancing by adjusting the cathode impedance of the cathode-follower stages. As shown in Fig. 1, each aerial, e.g. N, is coupled to a coaxial feeder 17 by means of a cathodefollower 9, the gain of which is separately controlled from a remote panel 28 by a variable resistance 29N connected in parallel with the cathode bias resistance 12 which is byepassed by the condenser 13 to prevent loss of signal along the control line 20 ; the fixed resistance 12 is not essential and may be omitted. In a modification, Fig. 1d, the gain of the cathodefollowers in each opposed pair N-S, E-W is controlled differentially by the potentiometers 29NS, 29EW and the gains of the two pairs is controlled differentially by the potentiometer 33, a fixed resistance 35 common to all the valves being included to compensate for changes in the operating conditions. If the cathode bias produced is excessive, it may be reduced by returning the grid lead to a potential divider connected across the H.T., Fig. 2 (not shown). Specifications 552,891 and 566,286 are referred to.

Filed: 1917-12-11
Abstract: 121,337. Railing, A. H., and Angold, A. E. Dec. 11, 1917. Globe-holders.-In a miner's electric lamp, a china bulb-holder and contact base G is held frictionally against a shoulder within the lamp head by a rubber washer E so as to be easily removable when the lamp-head has been taken off. Access can thus be had to the bulb and the interior of the glass B without detaching the latter from the lamp-head. The glass may be clamped between the washer E and an upper washer B<2> by an internal flange on the sheet-metal lamp head and by a sheet-metal ring F, which is notched to pass four metal blocks D and has inclined surfaces riding in grooves in the blocks so that after insertion it can be secured by less than a quarter turn.

Abstract: 457,834. Automatic control systems. GLYNNE, A., 6, Mildred Avenue, Sedgley Park, Prestwich, Manchester. June 27, 1935, No. 18362. [Class 38 (iv)] Electro-motive force.- In an alternator voltage regulating system wherein a field winding is energized from the alternator through a rectifier, the grid of a thermionic valve is energized in dependence on the difference between a rectified voltage obtained from the alternator and a constant unidirectional voltage, and the valve anode circuit contains resistance the voltage drop across which is applied between the grid and the cathode of the rectifier. In the form shown the voltage applied to the grid 14 of the triode 12 is the difference of that of the battery 15 and that derived from the alternator through rectifier 17 whilst the anode cathode path of triode 12 includes a resistance 11 which completes the grid-cathode circuit of the rectifier 7 in the circuit of the field winding 2 of the alternator or its exciter. The voltage obtained at rectifier 17 may be modified by a transformer having a winding carrying the load current when it is desired that the alternator voltage shall increase with load current. A polyphase rectifier may be used with a plurality of thermionic valves. Specification 457,814 is referred to.
