Abstract
The design of an automatic time-delay relay is described. For certain types of mercury-rectifier tubes no plate voltage should be applied for at least one-half minute after the filament current is turned on if the peak inverse potential exceeds 2100 volts. During a six-months´ test of this relay on a special radio transmitter it has not failed to function at any time.
