Abstract
523,616. Cathode-ray tubes. KOLSTERBRANDES, Ltd., and SHANNON, D. S. B. Jan. 10, 1939, No. 808. [Class 39 (i)] In a cathode-ray tube with magnetic deflection the ray is centred previous to deflection by deflecting plates arranged outside the stem of the tube. Fig. 1 shows a tube the stem of which has a conducting inner coating A in known fashion with windows in the coating outside which are arranged the deflecting plates C. The plates are supplied with suitable voltages from the potentiometers P1, P2.
