Title: Improvements in or relating to radio receivers
IPC: H03G3/22
Filed: 1940-09-28
Abstract: 543,503. Automatic volume control. FERRANTI, Ltd., and THOMAS, G. I. Sept. 28, 1940, No. 14686. [Class 40 (v)] A triode rectifier 19 is supplied with alternating current from a mains transformer 12 and so develops a direct current potential across resistance 25 causing cathode 20 to become positive relative to the anode 26. A diode portion of valve 19 is fed from a tuned intermediate transformer 3 so as to produce across resistance 21 a D.C. voltage proportional to the signal strength, which is applied as bias to the grid 23 of the triode. Thus with an increased signal the rectified current in the triode is reduced and cathode 20 becomes less positive. By suitably fixing the anode potential, a suitable negative A.V.C. potential may be taken from lead 18. More complex arrangements using a double-diode-triode are described (Figs. 2 and 3, not shown). Specification 529,590 is referred to.

Title: Improvements in or relating to reflected pulse vision systems
IPC: B44C7/02
Filed: 1946-05-17
Abstract: 612,348. Radiolocation; pulse-generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 17, 1946, No. 15069. Convention date, Nov. 17, 1944. [Classes 40 (vi) and 40 (vii)] In a system in which an area is scanned by a pulsed radio beam to produce an image of objects in the area on a cathode-ray tube scanned in synchronism and in which the rate of scanning is low compared with the pulserecurrence frequency so that any object in the area sends back a series of reflected pulses, increased brightness in the image is produced by connecting the reflected pulses to the cathode-ray tube through a capacity storage circuit. In the system of Fig. 1, transmitter 10 feeds pulses through the T-R box 12 to the aerial 13, 14, which is so mounted that it may be scanned, rapidly about the axis 17 by motor 18, and slowly about axis 19 by motor 21. The beam of the cathode-ray tube 24 is deflected in synchronism with the aerial scanning by feeding to the deflecting plates, through amplifiers 28, 36 triangular waveforms produced by the rotary-resistance generators 27, 34 driven by the motors 18, 21. Reflected pulses R, Fig. 3, from the receiver 16 are fed through condenser 43 and diode 41, to charge the capacity 49 in the input circuit of the cathode follower 48. The capacity may be formed solely of the circuit strays and the time constant is such that the potential at the grid 47 of the cathode follower is maintained at substantially the peak voltage of the pulse as shown at R<1>, Fig. 3. On the occurrence of each transmitted pulse T, the corresponding modulator pulse T<1> is fed to the grid 54 of valve 51, which is normally biassed off. Capacity 49 is thus discharged to a datum level at each transmitted pulse and the output voltage from the cathode follower 48 is fed as brilliance modulation to the C.R. tube.

Abstract: 779,882. Multi-stable state circuits. CINEMA-TELEVISION, Ltd. May 24,1955 [May 24, .1954], No. 15212/54. Class 40(6) The Figure shows a two stable-state circuit in which,discharge tubes 1, 2 are cross-connected so that one is normally operative and the other cut-off and in which tubes 3 and 4 are shifting tubes which are switched by the applied switching pulses. The common anode connections are made to an artificial transmission line or low-pass filter network 7-12, 13-18 which has a reflection less termination in an m-derived half section at its distant end, H.T. positive being applied at terminal 25. Initially the voltage at 6 is such that tubes 3 and 4 are cut-off and at 5 such that either of tubes 1 and 2 may conduct. If it is assumed that tube 1 is conductive and 2 cut-off then when a positive pulse is applied at 5 and a negative pulse at 6 tube 1. is cut-off and tube 3 conducts, tubes 2 and 4 remaining cut-off. Thus positive and negative-going signals are applied to the transmission line from the anodes of tubes 1 and 3 respectively and on reaching the grids of tubes -1 and 2 if the pulse at terminals 5 still persists no change occurs but if on reaching the grids of tubes 3 and 4 the pulse at 6 has terminated tubes 3 will be cut-off and tube 4 will conduct. When a further pair of pulses is received at terminals 5 and 6 tube 2 is cut-off and tube 4 conducts and a reversion to the initial condition with tube 1 conductive occurs. The capacitances 13-18 may be constituted wholly or in part by the interelectrode capacities of the tubes 1-4. Specifications 475,490 [Group XL] and 779,881 are referred to.

Abstract: 130,207. British Thomson - Houston Co., (General Electric Co.). Sept. 23, 1918. Electro-magnetic switches.-In a lock-out switch of the single-winding type described in Specification 11350/11, the pivoted switch lever which is normally in the open position is moved further in the opening direction to place a spring under strain when the current in the winding is above a certain value and is moved to the closed position by the action of the spring and the closing magnetic pull when the current falls below that value. The winding 10 surrounds the upper limb 11 of a U-shaped magnetic structure, the lower limb 12 of which supplies the lock-out pull on the lower end of the pivoted magnetic lever 20, the upper end of which carries the spring- mounted contact 21. The limbs are united by the magnetic cross-piece 15 from which extend on either side of the limb 13 additional magnetic limbs 12, the others ends of which are joined by a magnetic bridge 17 which exerts a closing force on the contact-lever. The lever is pivoted in a magnetic yoke forming an extension of the limb 11. A bracket 27 on the contact-lever carries an adjustable screw 26 which rests upon a spring plunger 25 mounted in a housing 29 adjustable in a lug secured to the cross-piece 17. With excess current the holding-out flux draws in the lower end of the contact member compressing the plunger spring 28. When the current falls off, the holding-out flux and the closing flux diminish to approximately the same degree, but the pressure of the spring 28 tending to initiate the closing movement remains constant and at a certain value of current the initial movement is given by the spring, thereby bringing the contact lever under the increased action of the closing flux and producing magnetic' closure. The limbs 12 are provided with short-circuited bands to delay the growth of the closing flux.
