Abstract: The present invention relates to a cassette for storing cinema film rolls (7). The cassette (14) comprises a first portion (15) and a second portion (16) which are essentially plane-parallel and separated by a spacing which exceeds the thickness of a cinema film roll (7) and connected by a connecting part (17). The cassette (14) also has an opening (18). The invention is characterized in that the cassette (14) comprises bearing supports (25, 26) for weight-relief against a horizontal circular table (4, 5) when the film roll (7) is moved between the cassette (14) and the circular table (4, 5). The invention also relates to a method of transferring a cinema film roll (7) between a storage cassette (14) and an essentially horizontal circular table (4, 5). The cassette is positioned so that bearing supports (25, 26) of the cassette (14) bear against the circular table (4, 5) and so that a contact edge (27) of the cassette (14) is fitted against the peripheral edge (28) of the circular table (4, 5). In this position, the film is moved between the cassette and the circular table. The present invention also relates to a rack (40) and a relief trolley (46) intended for cassettes (14) as described above.

Abstract: The housing of a motion picture projector has a chamber for a portion of a film-containing cartridge. The inlet of the chamber is surrounded by walls at least one of which extends into the path of movement of a cartridge into the chamber to be displaced by and to thereupon bear aginst the inserted cartridge, either owing to its resiliency or under the action of a spring. The movable wall can be moved to a closing position in which it closes the inlet and it can be held in the closing position by a cover for the housing or by a locking bolt. The movable wall can constitute a centering plate for the inserted cartridge and can be mounted for movement in and counter to the direction of insertion of cartridges into the chamber.

Abstract: Storage and transport apparatus for a web such as photographic film and the like. The film, which is stored in randomly formed loops within the cassette, is withdrawn from the cassette, passed along a film gate including a projection gate by a drive wheel and pinch rollers which contact the film along its edges, and then is returned to the cassette. The design of the film channel, along with the absence of conventional film storage reels, provides a film transport system having low inertia and resulting in rapid frame access time coupled with precision frame positioning.

Abstract: A motion-picture projector is adapted for the employment of a film cartridge of such a type as containing a film supply reel with the film trailing end secured thereto, and a take-up core with the film leading end secured thereto, which core is separable from the cartridge housing through a recess built up in one end of the cartridge. The housing is preferably made from two molded hair sections, one of which is formed with an opening through which a film rewinding spindle of the projector is engageable with the film supply reel, and the other being provided on the inner surface and at a portion corresponding in position to the opening on one of the half sections with a support for supporting the film supply reel to be held in such a manner that at least a portion of spindle hole of the reel appears in the opening formed on one of two half sections. The cartridge is initially set in a first position in the projector in which the spindle of the projector engages the supply reel, and then transferred to a second position due to rotation of a reel supporting member of the projector having said spindle mounted thereon. In the second position, the take-up core is gripped by a gripper on a take-up transferring member, so that upon the rotation of the take-up core transferring member the take-up core is transferred with the film leading end to a film winding position.

Abstract: A cinematographic projector comprises a light source, an objective, a film drive mechanism, a movable support for cassettes containing a spool of film, a temporary receiving member for the projected film, and a control mechanism for these devices. The movable support of the cassettes is displaceable horizontally in a direction perpendicular to the optical axis of the objective and comprises vertical compartments juxtaposed in the direction of displacement of the movable support and open at their upper end. Each compartment includes adjacent one end of its open upperedge, a first support member around which the cassette can pivot and a second support member withdrawing when the compartment is placed in extension of the optical axis of the projector. The cassettes in waiting position above the compartments and resting on the first and second support members tilt into their respective compartment around the first support member and are placed in film delivery position when the compartment is brought into the extension of the optical axis of the projector.

Abstract: A motion picture projector wherein the top wall of the housing is provided with an inwardly extending chamber for reception of smaller or larger magazines for motion picture film or for reception of smaller or larger exposed supply reels for motion picture film. The housing contains an automatic threading unit for the leader of motion picture film in a magazine and a manually operated threading unit serving for threading of motion picture film which is stored on an exposed supply reel. The reel can be mounted for rotation in the chamber by moving a mandrel from a retracted position to an extended position in which the mandrel extends through the central opening in the core of the reel. Such movement of the mandrel is utilized to move an obstructing member away from the inlet for manual threading of motion picture film which is stored on a reel.
