Patent number: 4171895Abstract: A photographic apparatus wherein the objective is movable by a focusing mechanism in response to manual rotation of a ring from a starting position. A spring biases the ring to the starting position through the medium of a follower which carries a blocking lever for the focusing mechanism. The blocking lever is moved from the path of a reciprocable spring-biased toothed rack of the focusing mechanism prior to unlocking of the rack by a lever which is disengaged from the rack during that stage of movement of the ring from its starting position which follows retraction of the blocking lever from the path of the rack. The focusing mechanism has a certain amount of inertia so that it does not change the position of the objective during movement of the photographic apparatus between different positions in which the objective is or may be trained upon objects located at different distances from the apparatus.Type: GrantFiled: December 1, 1977Date of Patent: October 23, 1979Assignee: AGFA-Gevaert, A.G.Inventors: Peter Lermann, Dieter Engelsmann, Herbert Wilsch

Patent number: 4104664Abstract: A still camera has a housing adapted to hold a roll of film having a succession of frames. An openable shutter is provided on the housing alignable with the film and a takeup wheel in the housing is connectable to the roll of film and rotatable to wind the film up and displace the frames one-by-one past the shutter. A film-advance slide is displaceable on the housing between a pulled-out position projecting from the housing and a pushed-in position fitting snugly with the housing. A transmission and a one-way coupling are provided in the housing between the slide and the take-up wheel so that the take-up wheel is rotated to wind up the film only on displacement of the slide from the pushed-in position to the pulled-out position. Furthermore, a frame-sensing mechanism in the camera arrests displacement of the slide or a portion of the slide in the direction toward the pulled-out position when a fresh frame is properly aligned with the shutter.Type: GrantFiled: January 28, 1977Date of Patent: August 1, 1978Assignee: AGFA-Gevaert, AGInventors: Alfred Winkler, Peter Lermann, Dieter Engelsmann, Gunter Fauth

Patent number: 4103993Abstract: A motion picture camera with variable focal length lens wherein the zooming collar and the distance selecting or focusing collar on the lens barrel are rotatable to neutral positions by an actuating member which is movable at right angles to or in parallelism with the optical axis of the lens. In such neutral positions of the collars, the focal length of the lens is satisfactory for the making of exposures in daylight or artificial light, and the distance setting corresponds to a distance of 4 to 6 meters to thus guarantee an acceptable depth of field for exposures of subjects located anywhere between closeup and infinity. The actuating member can further close a master switch to allow for starting of the camera motor in immediate response to depression of the release trigger.Type: GrantFiled: September 2, 1976Date of Patent: August 1, 1978Assignee: AGFA-Gevaert, AGInventors: Friedrich Winkler, Anton Theer, Peter Lermann, Volkmar Stenzenberger, Peter Griessner, Dieter Sandl, Hermann Muller, Herbert Wilsch

Patent number: 4097133Abstract: A cinematographic camera has a housing composed of a main section which carries at its narrow front side a photographic lens, and a cover section which straddles the main section and is provided with a viewfinder. The main section can be telescoped into and out of the cover section and in so doing respectively blocks and unblocks the viewfinder. A handgrip is pivoted to the main section and can be displaced between a position in which it hugs the main section and overlies the photographic lens which it thereby protects, and a position in which it projects from the main section so that it can be gripped by a user.Type: GrantFiled: February 28, 1977Date of Patent: June 27, 1978Assignee: AGFA-Gevaert AGInventors: Otto Stemme, Peter Lermann, Gabriele Ehgartner

Patent number: 4096491Abstract: The camera has a shutter release, a shutter, a device responsive to activation of the release for performing a retarded opening of the shutter, and a device operative when activated for causing the shutter to close. The exposure duration is controlled by an exposure control circuit. When the scene brightness level is within a first range, the automatically selected exposure durations are so short that, during a substantial part of the exposure, the shutter is in the process of changing from its closed to its fully open state. When the scene brightness level is within a second range, the automatically selected exposure durations are so long that, during a substantial part of the exposure, the shutter will already be in its fully open state.Type: GrantFiled: March 9, 1977Date of Patent: June 20, 1978Assignee: AGFA-Gevaert AGInventors: Eduard Wagensonner, Peter Lermann, Gunter Fauth

Patent number: 4096500Abstract: A scene-pause counter, a scene-production counter, and a repetition counter are connected in a series. Each counter furnishes its count to an associated comparator which also receives a signal from an addressable read-only memory. Pulse trains are applied to the counters. When a comparator in the series detects coincidence, it initiates counting by the next counter. When the last comparator in the series detects coincidence it can restart the first counter. A program-selector switch causes different address signals to be applied to the memory, resulting in different operations of different durations, in different combinations and sequences. This makes possible projection or exposure of single frames or series of frames with intermediate pauses between the projection or exposure of successive frames or series of frames, as well as repetitions of such combinations of operations.Type: GrantFiled: May 23, 1977Date of Patent: June 20, 1978Assignee: AGFA-Gevaert AGInventors: Peter Lermann, Eduard Wagensonner
