Electronic Light-Change Device

This paper describes a means of actuating scene-to-scene light changes in motion-picture printing. A conducting tape is applied to the printing negative by a special punch. This cues an electronic device which fires the light changing mechanism. The electronic device has a delay circuit which assures adequate time for the completion of the light-change operation.
