Abstract
589,135. Cathode-ray tubes. MULLARD RADIO VALVE CO., Ltd., and SHELTON, E. E. June 1, 1944, No. 10566. [Class 39 (i)] In a cathode-ray tube having magnetic deflecting coils, the internal cross-section. of the neck 1, Fig. 5, where it joins the bulb 3 is rectangular whereas the rest of the neck is cylindrical apart from a transition portion, the magnetic deflecting coils, 2 covering the whole of the transition portion and part of the cylindrical portion of the neck. The shorter side of the rectangle may be equal to the internal diameter of the circular portion of the neck, and the transition portion, which may be bounded by six substantially triangular plane surfaces 5, 6. 9, 10, 11 and 12, and two substantially trapeziform plane surfaces 7, 8, Figs. 4, 5, preferably extends over about half the length of the neck occupied by the deflection coils. The pressed glass bulb may also be of substantially rectangular cross-section. Specification 525,181 is referred to.
