    • A device for supporting and positioning the objective lens in an optical reading apparatus, such as, a video disc player, comprises a first pair of parallel leaf springs attached at one end thereof to a fixed support member for motion parallel to a record medium surface. A movable frame is attached to the other ends of the first springs, and a second pair of leaf springs movable perpendicularly to the record medium surface extend from the frame, the second springs being generally parallel to and between the first pair but with their faces perpendicular to those of the first pair. The objective lens is mounted at the free ends of the second pair of springs, and is movable electromagnetically in orthogonally related directions by means of coils and magnets associated with the objective lens and with the frame.

    • Apparatus and method for abrading or grinding a workpiece with great accuracy. An abrasive support unit is mounted on a vertical column for vertical and horizontal movement. The abrasive support unit is driven automatically along a linear horizontal path and transversely thereof while being driven rotationally. The abrasive support unit has an abrasive mounted thereon on a universal element that provides for universal movement of the abrasive. Servo means are provided for applying the abrasive support unit to the workpiece at a preset pressure. A detector in the form of a differential transformer detects variations in the pressure of application, due to variations in the uneveness of the workpiece, and develops a feedback input to the servo means for applying the abrasive support unit at the preset pressure.
