Abstract

575,962. Cathode-ray tubes. CHANCE BROS., Ltd., HOLMES, J. G., and ENGLISH, J. March 17, 1944, No. 5025. [Class 39 (i)] A cathode-ray bulb has the end part b formed as a cylindrical lens ; preferably it is separately moulded with a flange c which is subsequently fused to the body part a. If the outer surface is flat the viewing area may be formed with a raised portion e, Fig. 6, to facilitate grinding and to serve as a register for locating the bulb end accurately in its mounting.
