Abstract: An optical deflection system for deflecting a light beam for the purpose of scanning a computer store or matrix location, the apparatus including means for producing at a first mirror a line image which is reflected to a second mirror so that the line image at the second mirror is at right angles to the image on the first mirror and means for rotating the second mirror about an axis parallel to said line image at the first mirror thereby to deflect the line image reflected from the second mirror.

Abstract: A system for accelerating and decelerating a movable element of an actuator includes an inductive energy storage means, a circuit for producing a predetermined current condition in the inductor which holds the element in a balanced position and stores energy in the storage means, and switch means for discharging the storage means through the actuator to accelerate the element. The back E.M.F. developed by the motion of the element produces a current which opposes the accelerating current and thus applies to the energy store kinetic energy developed by the movement of the element.

Abstract: Apparatus is disclosed for simultaneously lapping spaced parallel faces on a workpiece by means of an elongate lapping tool which has a plurality of spaced lapping faces. The lapping faces may be formed as a helical surface on the lapping tool so that rotation of the lapping tool results in the faces on the workpiece being lapped by a number of separate portions of the helical surface and results in the workpiece being moved along the lapping tool so that each face is lapped successively by a number of different portions of the helix.
