Abstract :
The motor-operated rheostat with its associated apparatus now is replaced by a simpler, more compact vacuum-tube arrangement. The only auxiliary power required can be obtained from an ordinary station-lighting circuit; circuit constants are chosen so that momentary dips in this supply voltage do not affect the readings.
