Abstract
530,869. Valve-modulating circuits. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. March 17, 1939, No. 11654/40. Convention date, April 14, 1938 Divided out of 530,785. [Class 40 (v)] Ultra high frequency oscillations produced by passing an electron stream through an oscillating field so that cyclic variations in velocity are produced resulting in grouping in the electron stream, are modulated by applying potential at a point or points in the path of the electron stream. The Fig. shows a transmitting arrangement in which back coupling of the devices 104, 105 is effected through an additional resonant hollow body 106 of a lower frequency but operating at one of its harmonic frequencies to act as a master oscillator. The output is applied through a frequency multiplier 111 and amplifiers 112, 113 to an aerial 116. Modulation may be effected at any of the three tubes 117 and will produce both amplitude and frequency or phase changes, the former may be suppressed by applying the source through amplifier 120 to grid 121. Alternatively amplitude modulation may be supplied to grid 121 or to spaced plates 122 which deflect the electron beam. The plates 122 may be excited at the oscillating frequency and may be replaced by a deflecting resonant device as described in Specification 529,771 to increase the output. Amplitude modulation may be applied through transformer 118 between the electron source 114 and the resonant device 112. Specifications 517,264, 518,015, 523,712, 530,785, 530,870, 530,871, and 531,067 also are referred to.
