Abstract: 157,924. Huth Ges., Dr. E. F. March 22, 1919, [Convention date]. Void [Published under Sect 91 of the Act]. Thermionic relays and repeaters.-The anode current of a thermionic valve is varied by causing the applied energy to affect the temperature of the filament. Low-frequency variations of a microphone m react through a coupling t, with the heating-circuit of the filament K, which is made of such fineness that its temperature is correspondingly affected. The grid g is also coupled to the microphone circuit through a transformer t2. Where several strengthening-tubes are used in cascade, the microphone circuit may be coupled directly to the grid g<1> of the second valve through a transformer t3, t4, in addition to the usual anode coupling t5 between the first and second valves. The arrangement may also be used for high-frequency amplification.
