Abstract
702,504. Inductive-output tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 19, 1951 [Nov. 22, 1950], No. 27081/51. Class 39(1) In an inductive output tube the output system comprises a plurality of identically similar drum shaped cavity resonators 8, 9, 10 whose axial lengths are short relatively to the diameters and arranged coaxially in succession along the path of the beam the front and rear walls of the resonators being respectively connected by straight conductors 17, 18 lying near the beam passage apertures. The electron transit time from the front wall of one resonator to the front wall of the next is about a whole period of the oscillation frequency. The resonators are.disposed within and in good thermal contact with a metal cylinder 1 which has a closed end 20 serving as collector and coated to reduce secondary emission, and an open flanged end sealed to glass cylinder 2. The intensity modulating grid 5 is carried by disc 4 sealed between glass envelope parts 2, 3. Indirectly heated cathode 7 is carried on hollow tube 6 through which the heater supply leads are passed and tube 6 is sealed through glass envelope part 3 near to cathode 7, or remote from it as shown.
