Abstract

1,213,420. Electron guns. TELEFUNKEN PATENTVERWALTUNGS G.m.b.H. 29 Nov., 1968, No. 56840/68. Heading H1D. A cathode cylinder 2 is attached to a ceramic disc 10 provided with wedge-shaped circumferential portions 8 adapted when rotated to wedge the disc between a spacer 4 depending from the control electrode 1 and projections 3 pressed in the side of the electrode 1. This facilitates replacement of the cathode if the gun is to be salvaged from a scrapped cathode-ray tube. The invention is specially applicable to a triple electron gun with a convergence electrode for a colour television tube.
