Abstract

189,339. Welch, A. P. Nov. 16, 1921. Vacuum tubes.-A holder E has 'barriers H on the top, or underside, or both, between the contacts A - - D, so as to provide long leakage paths between contacts at different potentials. An additional contact F, engaging with the valve cap, may be connected to one of the contacts, or to a separate contact, for earthing.
