Abstract: A cylindric grid electrode for electronic tubes formed by a set of carbon threads or filaments which have been coated with pyrolytic graphite. The coated carbon threads or filaments can be arranged in various configurations within the superfices of the cylinder such as in circumferentially spaced relation parallel to the cylindric axis alone, or in combination with another set of the coated threads or filaments located in spaced relation perpendicular to the axis or obliquely thereto and which overlay the first set and are soldered to the latter at the points of intersection. The coated carbon threads or filaments may also be arranged in two sets of helices oblique to the cylindric axis and which criss-cross and are soldered together at their points of intersection.

Abstract: In mesh grids of comparatively large dimensions, measures are taken to prevent that said grids which are mainly used in metalceramic tubes deform under the influence of their own weight at high temperature. A sufficient increase of the mechanical stability of the grid is obtained if said grid comprises a few thicker wires in addition to the thin wires.

Abstract: A metal-ceramic tetrode or triode which comprises a cylindrical rod grid which is manufactured by means of a spark erosion process. In order to improve the mechanical stability of the grid and also to shift the resonant frequency to higher frequencies, the grid comprises wide and narrow rods. Since the wide rods bend inwardly or outwardly during the spark erosion process, the slots, to avoid said drawback, adjoining the wide rods extend in at least one inwardly extending flange of the cylinder farther in the direction normal to the curved surface of the cylinder than the slots present between the thin rods.
