Abstract

521,589. Radio receiving systems; preventing Interference. THORNTON, A. A. (Philco Radio & Television Corporation). Aug. 26, 1938, No. 25116. [Class 40 (v)] In a system for preventing interference the time constant of a resistance-condenser circuit 4, 5 is so chosen that a diode 14 in shunt to the transmission path acts as a short circuit for brief noise impulses but is non- conducting during the reception of prolonged signals. An additional shunt may be provided by a diode 13 which becomes conductive when a received impulse exceeds a predetermined amplitude. In a modified arrangement, Fig. 2 (not shown), the elements 5, 4 are in series across the transmission path with the diode in shunt to the resistance 4. The invention may be used in a remote control system as described in Specification 531,187.
