Filed: 1916-02-02
Abstract: 100,058. Bethenod, J., and Girardeau, E. Feb. 2, 1915, [Convention date]. Electric oscillations, producing.--In a method of producing electric oscillations, the discharge of the main condenser C is timed by the discharge of an auxiliary condenser K connected in parallel with the condenser C through an adjustable inductance L and resistance r. The discharge circuit of the condenser C is coupled inductively to the discharge circuit of the condenser K, the latter containing a rotary spark-gap e driven directly or through gearing from the shaft of the supply alternator. The dynamo exciting the alternator is preferably mounted on the shaft of the spark-gap e, so as to neutralize the play of the gearing due to variations in speed of the alternator. The resistance r and inductance l are so chosen that the condenser K is charged slightly in advance of the condenser U, so that the discharge current of the condenser K supplements the voltage of the supply transformer and produces a discharge at the gap E at the moment when the voltage of the condenser C is at its maximum.
