Abstract

For lengthwise transit of a film strip from one frame at a fixed station, to bring any other selected frame thereto, a counter is charged with the initial number of frames that must pass the station. A pulse is produced as each frame passes the station, to count down the counter. The pulses are also integrated to produce a true strip speed signal. With the use of the charge on the counter, a demand value signal is produced, corresponding to a constant fast velocity for all frames that must pass the station in excess of a predetermined number, and therebelow, to a decreasing velocity proportional to number of frames still to pass. The strip drive is energized according to the difference between true and demand values, in a manner tending to maintain that difference at zero.
