Abstract: A system and method for registering the frames of film with respect to an aperture in a motion picture projector. A registration reference mark is applied to each frame corresponding to the location of the frame on the film. When the film is intermittently stopped in the projector's film gate, the registration reference mark is read to determine the location of that frame relative to the immediately preceding frame. If the frame in the gate is misregistered, the gate is moved to correctly register the frame prior to projection. By properly registering the frames, the “jitter”and “weave” associated with conventional projectors is eliminated and resolution of the projected film image is enhanced.

Abstract: The invention relates to a system and mechanism of film feeding, traction, shuttering and adjustment in programmable audiovisual apparatus, with rapid frame change, which executes the indexing of one frame to the next one in accordance with a pre-established programmed signal, indexing only one frame at each signal, characterized by apparatus which renders the time taken to effect the frame change imperceptible and also allowing the establishing of all the stages of projection of animation, varying from one static frame at a time, up to the particular frame change speed desired.

Abstract: An apparatus for centering each film frame within a film gate of a motion picture projector. An intermittant film pull-down mechanism is mounted on a plate which is pivotally attached to the motion picture projector body so that as the plate pivots the position of the pull-down mechanism relative to the film gate changes, thereby changing each picture frame edge respective to the film gate. A specific embodiment defines a belt driven pull-down mechanism with a drive pulley located off the plate and utilizes a rack and pinion gear as a means for pivoting the plate.

Abstract: A cinematograph comprises a plurality of lenticules, a projection lens for capturing and passing optical flux from one of the lenticules, a light source for illuminating the image surface of a cine-film which is disposed in a plane which includes the focus of the lenticule and feed means for synchronously feeding the film and the lenticules.

Abstract: A modular film transport and control mechanism for selectively advancing either regular 8mm or super 8mm perforated motion picture film through a projection gate is provided. The module comprises a film transport shuttle having a film engaging claw biased for engagement with the perforations of the film, a rotatable drive cam in operative engagement with the shuttle to reciprocally move the claw along horizontal and vertical paths to advance the film through the projection gate, and a pivotally mounted projection mode shifter interposed between the shuttle and the cam to transmit the desired horizontal motion from the cam to the shuttle, and selectively movable between at least two positions along a surface of the cam to change the mode of operation from normal projection to still projection. A control linkage connected to the shifter permits manual selection of the desired operating mode. The module also comprises a rotatable shutter mounted on a common shaft with the shuttle drive cam.
