Title: Improvements in or relating to valve amplifiers
IPC: H03F17/00
Filed: 1944-08-04
Abstract: 585,419. Photo-electrically controlled amplifiers. GALL, D. C. Aug. 4, 1944, No. 14973. [Classes 40 (iii) and 40 (v)] [Also in Group XXXVI] In an amplifier employing a galvanometer responsive to the voltage to be amplified and having a zeroising feed-back from a gasdischarge valve or relay controlled by a photoelectric cell actuated by light from the mirror of the galvanometer and in which the relay has A.C. voltages applied to its anode and grid as described in Specification 537,784, means are provided for adjusting the relative phase of the voltages appearing in the grid and anode so that the relay affords an output representative of the input voltage to be amplified and does not oscillate readily. An A.C. feed-back to the galvanometer is also provided for preventing oscillations developing in the case of sudden movement of the instrument. In the drawings 1, 2 are the terminals over which the input voltage is applied to galvanometer G. Zeroising feed-back is derived from resistance 3 in the anode circuit of relay 5, which,has A.C. voltage applied to its grid and anode from windings 13, 19 of transformer 14, the phase of the voltage appearing on the grid being controlled by condenser 21 and resistance 22, one or both of which is or are adjustable, and by the impedance of the photo-electric cell 23. The adjustment is such that within the range of impedance variation of cell 23 the relay 5 is conductive at times when its anode is positive. The A.C. feed-back to the galvanometer is derived across resistance 35 and applied via transformer 33. The cathode of relay 5 is earthed, thus reducing unwanted pick-up.

In a magnetic store in which row and column conductors extend through a plurality of matrix planes while inhibit conductors are individual to each plane, the row, column and inhibit currents are derived from a common driving source which produces a composite signal at least one of the components of which is an alternating current. As shown in Fig. 1, a driving source S is selectively connected through row and column gates RL 1 -RL n and RC 1 -RC n  to row and column conductors L, C which extend through the cores T of four matrix planes M 1 -M 4 . Also inhibit gates RP 1 -RP 4  selectively connect the driving source to inhibit windings P 1 -P 4  of respective planes. The source S is fed by two current generators S 1 , S 2  of which one may be a D.C. generator and the other an A.C. generator. Alternatively, the two generators may produce fundamental and second harmonic frequencies respectively. Reversal of effective polarity for reading and writing is obtained in the source S which reverses the D.C. polarity or the phase of the second harmonic as the case may be. Reading and writing in the magnetic store is effected in the usual manner.

Abstract: 239,830. British Thomson-Houston Co., Ltd., (Assignees of Winter, F. H.). Sept. 15, 1924, [Convention date]. Selective distant control systems.-Selective distant control of a number of electric circuits is effected by unbalancing a relay which sets in action a travelling contact device arranged to restore the balance of the relay and thus bring the contact device to rest when the selected position is reached. In the system shown in the Figure a master rheostat 5 when set in a selected position puts a corresponding amount of resistance into the circuit of one of the relay balancing magnets 2, which closes the relay contacts 24, 25 and thus starts a distant motor 28 through reversing switches 59, 60 and a brake-releasing switch 40. The motor, through worm and screw gearing, drives the travelling contact member 22 over the successive contacts of the circuits to be selected 43 - - 51 and simultaneously puts sections of a resistance 6 into the circuit of the relay balancing magnet 3 which reopens the contacts 24, 25 when the selected position is reached. To make sure that the travelling member 22 takes up a position in the middle of the selected contact, hold-circuits for the magnets of the switches 59, 60 are kept alive by intermediate contacts 98 - - 106 for the necessary short interval after balance has been attained. Specification 26295/04, [Class 38, Electricity, Regulating &c.] is referred to.
