Abstract

777,030. Welding by pressure. RANGABE, A. R., and BUCKINGHAM, J. Jan. 13, 1953 [Jan. 16,1952], No. 1262/52. Class 83 (4). [Also in Groups XI, XXXVI and XL (a)] A collar 3 supporting the electrodes of a thermionic valve is preferably made of or coated with silver or gold and is welded within a vacuum chamber to the rim 5 of a metal envelope by pressing the parts against an anvil 35 by means of a support rod 16 and applying heat by means of an electric heating coil (not shown) arranged round the exterior of the anvil.
