Vacuum-tube circuit doubles speed of counter, with minimum of overheating and other damage to counter coil and mechanism. Operation depends on pulsed overvolting for a limited time, along with some sliding overvolting wherein excess voltage is applied to coil when circuit is first completed, then reduced so it drops below normal operating voltage during pull-in time.-R.
