Abstract

716,162. Cathode-ray tubes. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 6, 1952 [Oct. 9, 1951], No. 24980/52. Class 39(1) In a cathode-ray tube having a cathode, a control electrode, and an accelerating electrode separated by ceramic plates 7 and 9, the accelerating anode A<SP>1</SP> has studs 4 which extend through recesses in the ceramic plates and are provided with fastening abutments, such as hollow rivets or eyelets 2 which engage the ceramic plate 9. The control electrode has radical extensions 6 which are bent about the edge of the plate 7. The studs 4 are secured to metal strips 3 which clamp the anode A<SP>1</SP> to the support rods 15. The cathode which extends into a central aperture of the plate 9 is secured to the rods 15 by metal strips 14. The spacing between the cathode and the control electrode may be adjusted during assembly, by observing the front surface of the cathode through grooves 11 formed in the plate 9. A second or final accelerating electrode A<SP>2</SP> is also provided.
