Abstract

304,148. Otto, W. Jan. 14, 1928 , [Convention date]. Oscillation generators; local disturbances, eliminating.-In order to minimize disturbances liable to affect wireless receivers when using high-frequency apparatus comprising an electromagnetic make-and-break for therapeutic and like purposes energized from the electric light mains, the supply paths between the mains and the trembler contact or spark-gap are made electrically symmetrical. As shown, the trembler contact e, f feeds high-frequency oscillations through a transformer i, j to an electrode k. The mains supply to the trembler inductance passes through two equal and oppositely-wound coils c<1>, c<2>. Or a separate choke equivalent to the inductance coil may be inserted in the main a<2>. The object in both cases is to prevent high-frequency leakage into the mains network.
