DEFINITION

Classification: 352/160

(under the class definition) Subject matter including means to adjust the relative position of a film strip and the projection gate such that a frame of the motion picture is in registry with the gate, and/or means adjusting the shutter or other projector elements in connection with the adjustment of the strip carrier and projection gate for eliminating travel ghosts.

(1) Note. The term travel ghosts refers to the projected picture which results from the shutter exposing the frame before the frame has come into registry which results in plural images of the frame being projected with a vertical displacement.
