Abstract: The reversing film projection system employs film having images printed substantially side-by-side to allow presentation of one set of images in a forward direction and the adjacent images in rearward direction by moving the projection head and associated aperture plate and film guide laterally with respect to the lens and lamp house for display of the film images. In a first forward drive position, the projector motor drives the film in a forward direction with a first aperture of the aperture plate and associated first set of film images aligned with the optical train. Upon completion of the image presentation in the forward direction, the projection head is displaced laterally aligning a second aperture in the aperture plate and the associated second set of film images with the optical train, with the projection motor engaged in a reversed direction.

Abstract: A game simulating a sport such as football employs film sequences of plays of an actual game, using cassettes of film of equal length regularly disposed sequences. A sequence selecting apparatus and projector projects a given sequence determined by the selection of cassettes by one player and selection of sequence by another player. The apparatus employs a take-up reel upon which the film is wound before play to align the beginning of a sequence with an optical projection system, and spiral groove control device coupled to the reel for controlling the rotation of the reel to effect the projection of a single sequence. The optical system projects through apertures in the film cassette, and the shutter is operated by a sprocket coupled to the film.

Abstract: The disclosure relates to a rectilinear transport means particularly adapted for transporting a rectangular array of individual photographic film elements one at a time into register with the axis of a projector lens or the like or for the purpose of moving or controlling the movement of other objects in a generally rectilinear manner with respect to a generally rectangular array of elements or portions; the disclosure including a simple mechanical rotary actuator and indexing means wherein the rotary actuator continuously rotates in one direction and drives the indexing means back and forth in a generally serpentine path by engaging successively indexing portions spaced in rows generally parallel to each other and whereby the rotary phase direction of the rotary indexing means when it reaches opposite ends of the rows in the rectilinear path causes a reversal of direction in the movement of the indexing means so as to progressively move in one direction and then the other and wherein the disclosure also rela

Abstract: A continuous motion picture projection apparatus for use with a film strip having two side by side data tracks each comprising a photographic image track and a synchronized sound track. The first half of the program is carried by one data track and the other half by the second data track. The apparatus includes a main drive assembly which moves the film strip through the unit alternately in a forward and reverse direction and further comprises an illumination system, a projection lens system and a sound track sensor system. These systems are movable between a first position in alignment with the first data track and a second position in alignment with the second data track. Mechanisms associated with each of the systems are operably coupled with the main drive assembly and serve to automatically move the systems between their first and second positions upon reversal of the drive assembly.
