Abstract

21,252. Maiche, L. Sept. 25. Wireless telegraphy and telephony.-The transmitting and receiving circuits at one station for an inductive system of telephony or telegraphy are arranged as shown. A coil a, consisting of a few turns of thick wire, is used alone in transmitting, but is connected in series with a coil b, con sisting of a large number of turns of fine wire, for receiving; the circuit of the coil b is broken automatically, during transmission, by means of a Morse key c. The circuit of the coil a includes a battery n and a microphone o for telephony, or an interrupter for telegraphy, and the coil b is connected with a telephone h.
