Abstract

696,187. Control systems for X-ray tubes. NEWTON VICTOR, Ltd. Dec. 28, 1951 [April 6, 1951], No. 30334/51. Class 38 (iv). [Also in Group XL (a)] A grid-controlled X-ray tube derives its operating voltage from a transformer 41, the filament 24 being energized from a transformer 44. The control grid 33 is negatively biased from an insulating transformer 47 through a network 50, the grid voltage being approximately 180 degrees out of phase with the anode voltage. Suitable values for the resistance 5 and condenser 51 are given.
