Abstract

163,117. Macrorie, A. K., Airey, H. Morris-, and Shearing, G. Feb. 11, 1920. Frequency, measuring.-In a thermionic system for generating high-frequency oscillations for wireless signalling, a tuning circuit P, Q, which is tuned to the same frequency as the aerial, may include a low-voltage, low-resistance lamp E to indicate resonance, and may be calibrated to serve as a wave-meter.
