Abstract
The magnetic cuing device was designed to eliminate the necessity of cutting notches in the edges of motion picture originals used in film printers. — The method of magnetic cuing consists in painting a small dot of magnetic material on the edge of the film between two perforation holes. The paint may be placed on either the emulsion or base side of the film and still be detected by the low impedance (50-ohm) magnetic detector. — The equipment as designed contains two independent cuing channels, one for controlling printer-light changes and the other for controlling a fade-in or fade-out device which is built in on some printers. A mounting for two extremely small pickup heads has been designed to allow direct replacement of existing notch actuator switches in film printers.
