Abstract

19,102. Reineke, J. H. Aug. 29, 1911, [Convention date]. Direct-call systems.-Inductive telephony is arranged for in mines by using the cage cables as conductors. A resonating circuit D connected to a telephone is used as a receiver, and a transmitting microphone m and battery B are bridge across a part x, y of the cable.
