Abstract
895,451. Making electrodes. ELECTRIC & MUSICAL INDUSTRIES Ltd. June 18, 1958 [July 6, 1957], No. 21466/57. Class 83 (2). [Also in Group XL (a)] A method of making an electrode for a photomultiplier tube (see Group XL (a)) having a plurality of inclined slats comprises forming a plurality of interconnected slats and deforming the interconnections so that the longitudinal edges of inclined slats are brought closer together. The electrode is formed from a flat metal sheet 1 which is severed along the lines 4, 5 to form the slats 2 and the interconnecting side portions 3 are deformed by corrugating in a forming tool. The electrode is mounted in a frame 6 having a bent-over portion 10 and welded-on strip members 11 to locate and hold the corrugated side portions. The electrode may be of cylindrical or other curved form.
