Filed: 1928-03-03
Abstract: 306,292. Armstrong, J. J. V., (Telefunken Ges. f³r Drahtlose Telegraphie). March 3, 1928. Wired-wireless signalling.-In a high-frequency signalling system over power lines on which twoway communication takes place on different carrier-frequencies in each direction, the changeover from one carrier wave to another is effected when the tuned circuit is carrying substantially no current, so as to avoid sparking. To call a distant station the operator closes the switch gl, g2 by raising the microphones. This starts a motor A driving the high-frequency generator B. Simultaneously a winding U closes a contact u to switch in a condenser C2 to alter the tuning of the circuit L, Cl to the desired value, before the generator B has speeded up. When speech ends, the switch gl, g2 is again opened, but the relay U is kept energized by a contact h until the current through the coil H falls to a predetermined value, whereupon the contact h opens and throws the condenser C2 out of circuit. Should a distant station call up the station illustrated, both the contacts i are opened, so that the relays U and H are kept inactive even if the switch g1, g2 is closed, and the circuit L, C1 remains tuned to the incoming signal.
