Abstract

296,829. Wade, H.,' (Naamlooze Vcnnootschap Gloeilampenfabrieken). June 14, 1927. Arc and spark-gap apparatus; vacuum or lowpressure apparatus, arrangements of.-In a method of obtaining;'under the control of primary oscillations, secondary oscillations of lower frequency, the primary oscillations from a source 1 are impressed upon a circuit in which the secondary oscillations are generated by means of a battery 4, resistance 5, condenser 3, and discharge device 2. By adjusting the capacity of the condenser or the value of the resistance so as to control the rate of increase of the potential applied to the discharge device as indicated at a, Fig. 1, the frequency of discharge may be made equal to any desired integral submultiple of the frequency of the primary oscillations indicated at b.
