    Abstract: THE HOUSING OF A MOTION PICTURE PROJECTOR FOR 8MILLIMETER FILM HAS A GUIDE CHANNEL FOR AN ARCUATE MAGAZINE PROVIDED WITH COMPARTMENTS FOR FILM-CONTAINING CASSETTES. THE MAGAZINE IS MOVABLE ABOUT AN AXIS WHICH COINCIDES WITH OR IS NORMAL TO THE OPTICAL AXIS OF THE PROJECTION LENS, AND THE MAGAZINE CAN BE MOUNTED AT A LEVEL ABOVE OR BELOW THE OPTICAL AXIS. THE MEANS FOR INDEXING THE MAGAZINE CAN BE OPERATED BY HAND OR BY A REVERSIBLE ELECTRIC MOTOR WHOSE POLARITY IS AUTOMATICALLY REVERSED WHEN THE MAGAZINE REACHES THE ONE OR THE OTHER OF ITS END POSITIONS. THE DETENT MECHANISM WHICH SERVES TO YIELDABLY HOLD THE MAGAZINE IN A SELECTED ANGULAR POSITION IN WHICH A SELECTED CASSETTE OCCUPIES THE PROJECTION POSITION CAN FURTHER SERVE TO AUTOMATICALLY ARREST THE MOTOR FOR THE INDEXING MECHANISM, AND THE FILM WHICH IS BEING REWOUND ONTO THE SUPPLY REEL IN THE CASSETTE WHICH OCCUPIES THE PROJECTION POSITION ACTUATES A SWITCH WHICH STARTS THE MOTOR TO AUTOMATICALLY INDEX THE MAGAZINE BY A STEP.

    Abstract: A camera wherein the shutter is opened in response to closing of a first electric switch on deformation of a diaphragm which also effects movement of a holder for the switch with reference to the camera housing to thereby actuate a second switch or a mechanical device which triggers the operation of the exposure control or of an indicator for scene brightness. The holder is movable against the opposition of a spring or a rubber ring which yields to permit closing of the second switch or the operation of the mechanical device before the diaphragm closes the first switch.

    Abstract: A photographic camera for repeatedly exposing a single film through a grating in accordance with the carrier frequency method has a release element which indexes the grating with reference to the film prior to opening of the shutter. The film is pressed against the grating while the shutter is open and the cassette for film has a shade which overlies the film before the cassette can be removed from the housing of the camera.

    Abstract: THE HOUSING OF A MOTION PICTURE PROJECTOR IS FORMED WITH A CHANNEL FOR A SET OF CLOSELY ADJACENT CASSETTES EACH OF WHICH CONTAINS A SUPPLY REEL FOR CONVOLUTED MOTION PICTURE FILM. THE CASSETTES ARE MOVABLE STEPWISE BY AN ADVANCING MECHANISM SERVING TO PLACE SUCCESSIVE CASSETTES INTO A PROJECTION POSITION IN WHICH THE FILM IS AUTOMATICALLY DRAWN FROM THE RESPECTIVE SUPPLY REEL, THE IMAGES OF ITS FRAMES PROJECTED ONTO A SCREEN, AND THEREUPON RETURNED INTO THE CASSETTE, EITHER WHILE THE CASSETTE DWELLS IN THE PROJECTION POSITION OR WHILE THE CASSETTE DWELLS A REWINDING POSITION IMMEDIATELY DOWNSTREAM OF THE PROJECTION POSITION. THE MOTOR FOR THE ADVANCING MECHANISM IS STARTED IN RESPONSE TO TENSIONING OF FILM DURING THE LAST STAGE OF WITHDRAWAL FROM THE CASSETTE OCCUPYING THE PROJECTION POSITION, AND THE MOTOR IS ARRESTED BY A PORTION OF THE ADVANCING MECHANISM WHEN THE TRANSPORT OF CASSETTES BY A STEP IS COMPLETED.
