.~ Plural-parallel-section cathode with electrode surrounding each section
DEFINITION
Classification: 313/304
(under subclass 293) Discharge devices which have a cathode which is composed of a plurality of parallel sections, the apertured or grid-like electrode being provided with a plurality of tubular parts, each tubular part of the apertured or grid-like electrode completely surrounding a different one of the parallel sections of the cathode.
(1) Note. The tubular apertured or grid-like electrode sometimes has the form of a figure 8 in cross-section, a cathode section being disposed within each loop of the figure 8 with the cathode extending parallel to the longitudinal axis of the tubular apertured or grid-like electrode.
