Patent GB-180700-A (GB)
Abstract: 180,700. Th³ringische Landesuniversitõt Jena, (formerly Physikalische Institut der Universitõt Jena). May 27, 1921, [Convention date]. Induction, preventing and minimizing. - Comprises means for " dissociating " or preventing interference between two or more electrical circuits by the addition of current-carrying connections containing impedances which are inserted between points chosen according to instructions given in the Specification, and are adjusted by trial and error until interference is eliminated. For instance, two circuits 7, 8, Fig. 2, which are adventitiously coupled electrostatically, as shown diagrammatically at 9, 10, mav be dissociated by adding, a connection 11 containing resistance and capacity. Formulµ are given for this case and for circuits connected by contact or by mutual induction. Interference between two telephone lines or in exchanges can be prevented by one or more pairs of connections of the above type, or spontaneous oscillation in microphones and amplifiers can be prevented. Specification 147,013 is referred to.

Abstract: 657,116. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 7, 1948, No. 18204. [Class 39 (i)] The capacity of the target electrode is increased by disposing a continuous electronpervious metallic film in close proximity to, but out of contact with, the target electrode. Electrons formed at the photo-cathode 3 by the optical system 5 are accelerated by electrode 6 on to a target 2 comprising a sheet of very thin " conducting" glass, passing through a metallic film 17 carried on a metal mesh or grid 18 with a pitch of 0.001, the film being at a distance from the target 2 of less than the pitch of the mesh. The charge image is scanned from the other side of the target by a low-velocity beam from cathode 7, electrons not restoring the elemental areas of the target electrode to an equilibrium value being returned to a multiplier 14. The film 17 is at a potential of +1 to +5 volts higher than the equilibrium value of the target. The film is applied to the grid 18 by coating the latter with an organic film, sputtering or evaporating a metal on to the organic film which is later removed by solvent action. The metallic film may be used with a target scanned by a high-velocity beam.

[Class 40 (v)] Delayed A.V.C. potentials are derived from the grid current of a detector amplifier valve in which no grid current flows until the applied signal exceeds a certain value. As shown the grid current of valve 4 flowing in the resistance R7 produces an A.V.C. potential which is applied through the filter R8, C4 to the grid 2 of a previous amplifier 1. The initial grid biases of the valves 1 and 4 are determined by returning their grid circuits to selected points on a potential divider R1 ... R4, that of the former being adjustable by a variable resistance R9.

[Also in Division H3] In an electronic delayed action supply source having an oscillator 10 connected to be energized from a unidirectional input voltage 1, 2, means is provided for delaying the operation of the oscillator by a predetermined time after the input has been applied and a unidirectional output is obtained by rectifying and filtering the output from the oscillator which ceases to oscillate immediately the incoming input voltage ceases. The input to the transistor oscillator 10 is stabilized by Zener diode 6 and charges a four-terminal capacitor 15 via a variable resistor 19 which gives a variable time delay. After a predetermined time the voltage across capacitor 15 is sufficient to cause the transistors 7 and 8 to oscillate. The output from the oscillator feeds part of a tuned winding of a transformer 25 via a transistor 21. Impedance matching between the output of transformer 25 and the output circuit 3, 4 is obtained by emitter follower 27 which feeds the rectifiers 31 and four-terminal capacitor filter 32. When the input at 1, 2 is removed the oscillations cease and the output pulse ends.
