Abstract

190,505. Ransford, R. B., (Soc. Franþaise Radio-Electrique). June 24, 1921. Atmospherics and undesired signals, eliminating or limiting.-In a receiver designed to prevent interference, a current limiter for reducing the strength of disturbances to that of signals is arranged between two groups of resonators one of which is highly damped and the other only slightly damped. The highly-damped resonators are tuned circuits, the others may be tuned circuits of the wave or note frequency or mechanically tuned devices capable of passing on signals. Resistances w<1> - - w<4> provide damping for the aerial and the resonators R' - - R<3>. A current limiter is connected at V and resonators R<4>, R<5> having small damping pass the signals on to an indicator T.
