Cue Analog: A Nonphysical Negative Cuing System

Cue Analog is a system whose purpose is to eliminate notching, tape application, gratings and the handling of negative material during cuing. Foot and frame information is punched into the same tape containing additive light information and is read consecutively. A photoelectric transducer mounted on the printer feeds frame information to a counter. When the counter matches the punched tape, foot and frame data for a scene change, the system gates a signal to the additive light system for a modular or valve change. Also described is the bidirectional cue analog on a new panel printer, a unidirectional cue analog on a new panel printer, a unidirectional system on a new high-speed step-reduction printer and the programer for the new tapes.
