405,176. Discharge apparatus. MULLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. June 9, 1933, No. 16575. Convention date, June 23, 1932. [Class 39 (i).] An X-ray or other high voltage tube has a protective casing which comprises a metal cover and which forms a unitary structure with the tube and a rounded solid body is connected to the anode and extends beyond the insulating parts of the structure into the space defined by the metal cover. The body may be connected to the anode by a rod of diameter less than that of the anode, or by a rod of a material having a lower heat conductivity than that of which the anode is made, e.g., of aluminium if the anode is of copper. In one form Fig. 1 a metal casing 1 surrounds the end of an X-ray tube 2 which is enclosed in an insulating jacket 5. The anode 4 is roughened and blackened and is connected by a rod 6 to a rounded body 7. In a modification the anode is mounted on a ring of ferrochromium sealed to the outer glass wall of the tube.
