A plastic television chassis adapted for use in combination with a cathode-ray tube within an enclosure includes a base having integral snap-together parts disposed at opposite ends thereof. A pair of side frames are attached, respectively, to the opposite ends of the base in a substantially orthogonal orientation. Each side frame has integral snap-together parts disposed adjacent a first edge thereof for mating with the snap-together parts of the base, and also has integral slidable-groove parts disposed along a second edge thereof adjacent the first edge. A panel is attached to the side frames by integral slidable-groove parts disposed along opposite sides thereof for mating, respectively, with the slidable-groove parts of the side frames.

Television chassis

A photomultiplier tube comprises an evacuated envelope having a generally cylindrical sidewall with a faceplate closing one end of the envelope. A conductive coating is disposed on a portion of the sidewall adjacent to the faceplate. A photocathode is formed on the faceplate and on a portion of the conductive coating. An electron multiplier assembly including a plurality of electrodes is spaced from the photocathode. A plurality of leads extend from the electrodes to a plurality of terminals in a base attached to the tube. A resilient electrical contact member is connected to a terminal in the base for applying a potential to the photocathode. The electrical contact member has a pair of support tabs at the opposite ends of the member. The tabs are affixed to the multiplier assembly so that the contact member assumes a substantially arcuate shape which contacts and conforms to a large area of the conductive coating on the sidewall of the envelope.

Broad area cathode contact for a photomultiplier tube

A photomultiplier tube comprises an electron multiplier assembly including a pair of oppositely-disposed insulative support spacers. A plurality of elements including an ultimate dynode and an anode are affixed to the support spacers. The ultimate dynode comprises a relatively inflexible multilateral hollow member having two plane-face surfaces lying at an acute angle to one another and terminating at a lower transverse edge. The ultimate dynode includes dynode mounting tabs extending from opposing ends thereof for affixing the ultimate dynode to the support spacers. The anode includes a substantially flat electron permeable mesh portion spaced from one of the plane-face surfaces of the ultimate dynode. Anode mounting tabs extend from opposing ends thereof for affixing the anode to the support spacers. Electrical leakage isolation slots are formed in the support spacers to increase the electrical leakage path length across the support spacers between the ultimate dynode and the anode.
