Abstract

523,712. Electron oscillators ; wireless circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Oct. 10, 1938, No. 29310. Convention date, Oct. 11, 1937. [Classes 39 (i), 40 (iii) and 40(v)] In an ultra-short wave oscillation generator a beam of electrons is passed through an oscillating field which causes cyclic variations of the electron velocities in the beam and results in groups of electrons travelling along the beam, these groups supplying power to a resonant circuit. In a self oscillator a beam formed by a cathode 4 and grid 20 enters a first "grid," resonator 21, with grids 9, 10 at its entrance and exit spaced apart a distance giving an electron time flight from 9 to 10 equal to less than a half cycle or a half cycle of the oscillating field or an odd multiple thereof. Some electrons are accelerated and some retarded by this resonator and after passing through the unipotential space 24 where the electrons form spaced groups they enter a second "anode" resonator 25 with grid 27 at its entrance and anode plate 12; the plate 12 may be replaced by a permeable part, the beam passing out of this second resonator. The time of flight between grid 27 and plate 12 is an odd number of quarter cycles given by 4n Π1. The bunched electrons impart oscillations to the second resonator ; its oscillation period is adjustable by making the walls resilient by means of slits, an adjusting screw 34 being attached to the plate 12. The oscillations in the two resonators are stated to take place wholly on the inner surfaces so that they are shielded from each other ; the resonators are earthed and are coupled by a loop 30. Radiations can be taken from this loop or if the slits in the walls of the resonator 25 were big enough power would be resonated thereby. Electrical or magnetic focusing may be used to direct all the electrons from the cathode through the resonator 21 and the grid 27. In a modification annular resonators 21<SP>1</SP>, 25<SP>1</SP>, Fig. 7, toroid in cross section are used with a ring-shaped cathode 50 carried on a plate 4. For work as an amplifier a grid loop 54 is carried by the first resonator and an anode loop 15 by the second. The first grid 9 may be in the form of wires running in one direction only and the grid 27 then has the wires in a direction at right angles to those in the grid 9. Specification 517,264 is referred to.
