Abstract

205,038. PÚri, F. Oct. 7, 1922, [Convention date]. Vacuum tubes.-The anode of a thermionic valve is in the form of a straight prism consisting, either of two plates 10 intersecting in a straight line parallel with the filament, or of a triangular prism. A groove is provided at the junction of the plates for attachment to a support. The grid 12 may be of folded zigzag form. The support for the filament 9 may be protected by a quartz or other sheath. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an anode formed by two parallel plates. This subject-matter does not appear in the Specification as accepted.
