Abstract: There is described a marking method for distinguishing the kind, depth, position and area of surface defects of a metal piece as well as a method for detecting marks on the metal piece and a method for arranging detected signals in a electronic computer to automatically control scarfing. Shapes and colors of the marks respectively correspond to either the kind or depth of the surface defects of the metal piece. The marks are detected by a photosensitive means which can recognize colors of the marks, for example, industrial color television camera. Output signals of the camera are transmitted to the electronic computer. The computer arranges the signals and processes them to automatically control the scarfing machine.

Abstract: This invention is directed to a method for making intricate inlay designs in wood and other materials. The novel method of this invention uses a laser to selectively form patterns in two pieces of material by vaporizing unwanted portions thereof. One piece of material has the negative pattern of the other piece of material. Unlike previous methods of making inlays, these patterns do not penetrate completely the thickness of the pieces. A suitable adhesive is then applied to the pieces of material. The two pieces of material are then mated together so that the vaporized area of one piece mates with the raised (non-vaporized) area of the other piece. When the adhesive has set, one surface is sanded or planed until the thickness of the joined pieces is reduced to include the area where the two pieces have been mated. This area will be an intricate inlay which will be composed of both pieces.

Abstract: A static electro-optic crystal deflection element, subject to electrical control of refraction, is used as an inertialess compensating element in mechanically controlled projection systems for laser beams. Electrical signals derived from the moving parts of the control mechanism are applied to the crystal to produce compensating refractions of the laser coordinated with short increments of movement of the mechanism. In one application blurring effects associated with continuous rotation of a multifaceted deflection mirror in a photographic tracing system are nullified by electro-optic compensation. In another application distortion due to relative motion between a sensing laser and a rotating drum containing a series of hologram records is cancelled by electro-optic effects coordinated with individual record movements.
