Abstract

611,101. Filament supports for thermionic valves. HIVAC, Ltd., RANGABE, A. R., and WRIGHT, C. S. Feb. 6, 1945, No. 7663/48. Divided out of 611,034. [Class 39 (i)] The filament of a thermionic valve secured by tags to one insulating support is held under tension by a helical spring under compression located on the side of a second insulating support, the spring having a central hook 60 which supports the filament so that the coils 56 of the spring screen the electron emission occurring beyond the range of the grid. At the base, the wire is parallelogram-shaped 57, 58, 69 to fit neatly in a hole in the insulating mica support. The spring has an insulating cover. The Specification also comprises the subject-matter of Specifications 611,033, 611,034 and 611,035 which are referred to.
