  • Patent number: 3968506
    Abstract: Image display from a continuously moving image carrier with the aid of a repeatedly advanced and reset optical compensator is improved by omitting the traditional compensator bias spring and resetting the compensator with electric power pulse doublets. A substantially constant driving torque may be provided for the compensator in proportion to a damping term of the compensator equation of motion. An electric bias may alternatively or additionally be provided for biasing the compensator during image display against the direction of advance motion. Decelerating power may selectively be applied to the compensator to prevent or correct overshooting in the advance direction.
    Type: Grant
    Filed: December 19, 1972
    Date of Patent: July 6, 1976
    Assignee: Bell & Howell Company
