313,527. R÷hm & Haas Akt.-Ges., (Assignees of Ges. f³r Strahlungschemie Ges.). June 12, 1928, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes.-Alloys particularly for the production of foil, sheets, membranes, or the like permeable to cathode, R÷ntgen, and like rays, consist of 85-97 per cent of beryllium and 3-15 per cent of gold. The metals may be melted together in a vacuum, or the gold may be used in the form of gold amalgam, the mercury distilling off during the fusion.
