  • Film advance mechanism for motion picture apparatus
    Patent number: 5841514
    Abstract: A motion picture apparatus and method for intermittently advancing motion picture film by forced air. The film is initially placed into successive loops formed by a cam-driven flipper. The loops and thus the film are advanced through the projector or camera pathway by a forced air blower which propels the successive loops through a projection pathway. Vacuum pressure may also be applied to the film through a gate to secure the film to the gate with linearly arranged register pins steadying the film over a projection aperture. The film is rewound through the projector by a motorized rewind with a positive pressure applied to the film through the gate.

  • Film advance mechanism for motion picture apparatus
    Patent number: 5633696
    Abstract: A motion picture apparatus and method for the advancing motion picture film through the apparatus sequence by forced air. The film is initially placed into successive looped configurations formed by a cam-driven flipper. The loops and thus the film are advanced through the projector or camera pathway by a forced air blower which propels the loop through a projection pathway. Vacuum pressure is also applied to the film through a gate to secure the film to a gate with linearly arranged register pins steadying the film over a projection aperture. The film is rewound through the projector by a motorized rewind with a positive pressure applied to the film through the gate.

  • Motion picture projection apparatus
    Patent number: 5341182
    Abstract: A motion picture apparatus for the projection of motion picture film which advances the film through the projection sequence by forced air. The film is initially placed into successive looped configurations formed by a cam-driven flipper. The loops and thus the film are advanced through the projector pathway by a forced air blower which propels the loop through a projection pathway. Vacuum pressure is also applied to the film through a gate to secure the film to a gate with linearly arranged register pins steadying the film over a projection aperture. The film is rewound through the projector by a motorized rewind with a positive pressure applied to the film through the gate.
