Abstract
728,999. Caps for thermionic valves. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 11, 1953 [May 14, 1952], No. 13072/53. Class 38 (1). [Also in Group XL (a)] In a cathode-ray tube comprising a dished or flanged glass window 2 sealed to a glass cone 1 which has an inner conductive coating 6, this coating connects to an external terminal 4 which is secured to a metal strip 3 of U-section embedded in the seal between window and cone. The strip may be of ferrochrome, with a press-stud shaped terminal 4 welded to it.
