  • Patent number: 6161933
    Abstract: A device for controlling, regulating and monitoring a cine camera with a control and/or data detection unit which is connected to devices for controlling and/or detecting camera or recording functions, and connected to operating and control devices for controlling and monitoring camera and recording functions.
    Type: Grant

  • Patent number: 5175573
    Abstract: Apparatus for intermittent or continuous transport of a film using a film transport device comprising a drive motor whose shaft firstly is connected with a sprocket engaging at least one row of holes in the film and secondly with a position sensor which delivers position signals corresponding to the angular position of said motor shaft, to a control and regulating device whose output controls the drive motor through a DC amplifier, so that during intermittent transport of the film, each film pitch is subdivided into at least one acceleration phase, one deceleration phase, and one position-regulating phase, said phases preferably having variable or programmable lengths, with the set values for the acceleration and deceleration of the film transport device having their rises limited.

  • Patent number: 5121982
    Abstract: Film transport device in a film projector with winding plates located on both sides of a film gate and drivable by one winding motor, with supply and takeup devices respectively located between the winding plates and the film gate to create film loops on both sides of the film gate, a film transport device between the supply and takeup devices, and a film channel to guide the film placed in the film projector. After film (1) is placed in the open film channel, film transport device (2) and one of the two supply and takeup devices (3, 4) is brought into engagement with film (1) and film transport device (2) is operated at an rpm greater than that of one of the supply or takeup devices (3 or 4) until a first film loop of a presettable length is formed between film transport device (2) and one of the supply and/or takeup devices (3 or 4).

  • Patent number: 5106185
    Abstract: Control and regulating device for film transport in a film projector, with winding plates (62, 72) located on both sides of a film gate (8) and drivable by a single motor (61, 71), and with supply and takeup devices (3, 4) likewise disposed between the winding plates (62, 72) and film gate (8), the devices being drivable by at least one drive motor (51) to produce film loops on both side of the film gate (8) and with a transport device (2) between the supply and takeup devices (3 and 4). The drive motors (21; 51; 61, 71) for the winding plates (62 and 72), supply and takeup devices (3 and 4), and film transport device (2) are connected with sensors (25; 55; 65, 75) to detect the rpm and/or rotational direction, so that when a presettable rpm is exceeded or when one of the drive motors (21; 51; 61, 71) rotates in a rotational direction counter to the rotational direction predetermined by a higher-order operating control, all drive motors (21; 51; 61, 71) are braked simultaneously.

  • Patent number: 5082357
    Abstract: Method for correcting vertical framing errors during the projection of an intermittently transported perforated motion picture film by means of a film transport sprocket engaging the film perforations, said sprocket being driven by an electric motor whose rotor is connected with an angle indicator device which delivers to a regulating device controlling the electric motor, position signals corresponding to the angular position of the rotor. To correct device-specific vertical framing errors, the frame positions are measured with a geometrically precise measuring film over a plurality of frames, the individual frame positions are stored, and the position of the angle indicator disk is changed by a correction value relative to the film transport sprocket.
