Applications of Transfluxors to an Electromechanical Control System

A control system using multiaperture magnetic cores of the transfluxor type provides a reliable method of commanding paper advance and auxiliary functions in a photographic printer. The transfluxors are operated in a mode which permits larger variations in drive control pulses and which is less sensitive to extraneous signals. Coupling to the mechanical system is done via thyratrons to clutches and relays. Advantages over a purely relay or flip-flop logic for this control purpose are discussed briefly.
