Abstract: A flat grid of pyrolytic graphite is obtained by cutting a disc from a cylindrical blank followed by deformation under pressure and by means of a partial vacuum. The grid is then machined and stretched within a stressing frame which also serves to mount the grid within the electron tube.

Abstract: In an electron tube having coaxial cylindrical electrodes and at least one cylindrical grid of pyrolytic graphite, the grid is joined to the upper portion of a central conducting mast by means of a bell which is also of pyrolytic graphite and fixed on the mast. Slits are cut at uniform intervals around the periphery of the bell in order to form resilient strips which serve to establish an electrical contact between the grid and the conducting mast.

Abstract: The method according to the invention comprises winding a metal wire substantially helically both round a fitting constituted by a flexible strip and around two rods arranged parallel to the fitting axis and on either side of the fitting. The rods are eliminated when the metal wire is wound. The fitting comprises means limiting the displacement of the wire in accordance with the fitting axis, which coincides with the axis of the helix according to which the wire is found. These means are constituted by two rows of slots made in the lengthwise direction on two opposite edges of the strip constituting the fitting.

Abstract: A directly-heated cathode for power electron tubes such as triodes, tetrodes or pentodes comprises a cylindrical sleeve constituted by a lattice of crossed wires forming the emissive portion of the cathode and by two conductive plates attached respectively to each end of the sleeve. In order to permit free deformation of the cathode, a flexible metallic bellows element is fixed between one of the plates and the corresponding end of the cylindrical sleeve.

Abstract: A thin-walled grid of pyrolytic graphite for a high-power electron tube such as a triode or tetrode has a lower end in the form of a bell-shaped sleeve provided with uniformly spaced longitudinal slots which stop short of the edge of the sleeve. The solid edge portion thus formed beneath each slot serves to fit the sleeve over a metal ring of the electron tube base. The grid sleeve is clamped against the metal ring by means of screws engaged in internally-threaded bores of the ring. The edge portions of the graphite sleeve are thus fractured so as to form longitudinal strips which compensate for differences in expansion between the graphite and the metal while ensuring good electrical contact.
