Abstract

520,374. Cathode-ray tubes. PHILIPS LAMPS Ltd. July 10, 1939, No. 20098. Convention date, July 12, 1938. [Class 39 (i)] The core on which one or both pairs of deflecting coils 7, 8 and 9, 10 are mounted is formed of laminations 1 the spacing of the laminations being at least of the same order of magnitude as the thickness of the laminations. Between the laminations are insulating spacers 6 at their overlapping ends and thicker spacers 6<SP>1</SP> near the mounting holes 5.
