Patent number: 6575852Abstract: An apparatus for centering a ball is disclosed. The apparatus comprises a base, an upright member supported on the base for pivotal movement with respect to the base, and a pivot arm pivotally supported relative to the upright member for pivotal movement between a first, cocked position and a second, released position. A ball cradle is supported on the pivot arm for releasably supporting a ball to be centered. A bias member urges the pivot arm towards the second, released position and a pivot arm lock is operable, in a first condition, to hold the pivot arm in the first position. The pivot arm lock, in a second condition, releases the pivot arm so that the bias member moves the pivot arm to the released position, thereby centering the ball. The apparatus preferably includes sound actuated means for changing the condition of the pivot arm lock from the first condition to the second condition, to center the ball.Type: GrantFiled: November 8, 2001Date of Patent: June 10, 2003Inventor: Randy Orner

Patent number: 6523443Abstract: The present invention is a process by which optical surfaces of lenses, particularly plastic progressive lenses and molding shells for producing lenses are manufactured directly in a single step according to didicidual data. A blank from which an optical surface or a molding shell is to be manufactured is held at the workpiece carrier of a spindle axis (Z axis) of a shaping machine and is directly turned into its final form by a turning tool which can move relative to the blank (in the X axis), i.e., transversely to the direction of displacement of the tool. During each rotation of the spindle, the turning tool is incrementally adjusted towards or away from the blank depending on the characteristic surface data, which may be predetermined or calculated on-line.Type: GrantFiled: December 30, 1998Date of Patent: February 25, 2003Assignees: Carl-Zeiss-Stiftung, Heidenheim/Brenz, Fraunhofer-Gesellschaft zur Forderung der angewandten Forschung e.V.Inventors: Albrecht Hof, Klaus Mehlkopp
