Abstract: Method of manufacturing grid electrodes wherein a grid sleeve is produced by depositing pyrolytic graphite on a polished mandril of glassy carbon and provided with apertures by means of the laser beam, then the finished grid is provided, by means of hot gas pyrolysis, with a second layer of highly oriented pyrolytic graphite, and thermally and/or mechanically after-treated at 3000.degree. to 3800.degree. K and 10-500 bar.

Abstract: An impervious metal sheet is placed on top of a pair of flat grid blanks which are clamped together at their edges. An elastic sheet contacts the bottom grid blank, and a second impervious metal sheet is inserted between the two grid blanks if the grids have high percentage open areas. All of the blanks and sheets are dished simultaneously by forcing fluid to inflate the elastic sheet. The dished grids are also stress relieved simultaneously.

Abstract: A vane grid is disclosed wherein a plurality of inwardly directed vanes are bonded at their roots to the sidewalls of an array of longitudinal slots in the inside wall of a grid ring. The grid is conveniently fabricated by machining a plurality of grid rings, stacking the grid rings, and broaching the array of slots in the inside walls of the stacked grid rings. The grid rings are then plated, the vane members assembled, and the assemblies are heated to melt the plating to form, when cooled, a bonded joint between the root portions of the vanes and the grid ring.

Abstract: The effects of high field emission upon electrodes and screens in high vacuum tubes or switches is reduced by coating copper electrodes with a thin layer of titanium or zirconium. As a result of this, the allowable field strength is increased.
