NUMERICAL DISPLAY TUBES CONTROLLED BY PULSES PRODUCED BY VOLTAGE INVERTER AND DIRECTED BY SWITCH DEVICE TO EACH TUBE IN SUCCESSION

摘要

A circuit arrangement for controlling the operation of numerical display glow tubes and including means for producing a train of pulses of sufficient voltage to operate such tubes and switching means connected between the voltage pulse producing means and the tubes for applying the pulses directly to each tube in succession and also causing the pulses to directly control the switching operations of the switching means.
