87.~ With particular pulsing means


DEFINITION

Classification: 331/87

(under subclass 86) Subject matter wherein an electrical network including switching or keying means is provided for producing high voltage pulses of large energy content, which pulses are applied between electrodes (cathode and anode) of the active element of the oscillator to cause the oscillator to generate oscillations in accordance with the duration of the pulses.
