Abstract: 182,107. Jouaust, A. June 22, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic detectors; heterodyne receiving systems.-In a system for receiving continuous waves the signals are modulated at the receiving end by a source of high-frequency oscillations and are not rectified. As a result, frequencies of N+N<1> and N-N<1> are produced where N and N<1> are the frequencies of the signal wave and the local source. The frequency N-N<1> is audible. In case the received waves are modulated at the transmitter, N is made equal to N<1>. As shown in Fig..1 signals are led to the grid of an amplifying-valve 1 the anode circuit of which is supplied from a high-frequency generator such as the valve 15. The signals are audible in the telephones 11 shunted by a condenser 12. In a modification the anode circuit of valve 1 is supplied from the ends of an impedance in the anode circuit of valve 15 instead of from condenser 10. In a further modification, Fig. 3, a single valve is used oscillating at a frequency determined by the circuit 24, 25, for both receiving and modulating the signals. The back coupling is provided by the condenser 29.
