Abstract :
ELECTROMECHANICAL relay circuits, which recognize the appearance and disappearance of electric pulses representing events to be counted and which establish unique conditions during and after each successive pulse, or after a particular number of pulses, are termed relay counting circuits. With such circuits, the number of preceding events can be determined by the operated combination in which the relays comprising the circuit stand. Electrical paths through the contacts of these relays may therefore represent digits in a numerical system.
