Abstract: Method and apparatus for transferring a design by projecting the design onto a flat or arcuate surface and etching and/or selective plating. The design is transferred to the image surface by passing light through a transparency, or by reflecting illuminating light from a surface, bearing the design in rectangular-coordinate form and formed into a cylinder and then redirecting the light such that the design is projected upon and received by corresponding areas of an image surface which is or has been photosensitized. The design appears on a flat image surface in a foreshortened circular form, and is adapted for subsequent formation into an arcuate surface bearing the design in undistorted form. The design also may be projected either directly, or from a flat image surface transparency, upon an arcuate image surface in undistorted form.

Abstract: Method and apparatus for producing evident permanent surface markings, such as for serializing, hall-marking, identifying and/or personalizing, on a glazed surface without refiring or piercing the surface, by metal deposition and bonding from a guided contacting metal writing rod. The marking material is transferred from the writing rod and bonded to the glazed surface by progressively applying the pointed end of such rod of bondable metal to the moistened glazed surface through the desired marking pattern with sufficient pressure and motion rate to produce an evident marking.

Abstract: Method and apparatus for producing a design on a flat or arcuate image surface by projecting from a rectangularly disposed design and etching and/or selective plating. The design is transferred to the image surface by passing radially columnated light through a rectangular transparency bearing the design and formed into a cylinder and then redirecting the columnated light such that all areas of the design are projected upon and received by corresponding areas of the image surface which is or has been photosensitized. The design appears on a flat image surface in a foreshortened circular form, and is adapted for subsequent formation into an arcuate surface bearing the design in undistorted form. The design also may be projected directly upon an arcuate image surface in undistorted form.

Abstract: Method and apparatus for producing a design on a preformed arcuate surface by etching and/or selective plating. The design is transferred to the arcuate surface by progressively and successively projecting narrow images of the design from a flat form and progressively rotating an arcuate surface about its axis such that the narrow images of the design are successively projected upon and received by corresponding portions of the arcuate surface.

Abstract: Method and apparatus for producing a design on a flat surface by etching and/or selective plating. The design is transferred to the flat surface by progressively projecting successive narrow transverse images of the design from a rectangular transparency and progressively rotating the flat surface about an axis such that the narrow images of the design are successively projected upon and received by corresponding radial portions of the flat surface which is or has been photosensitized. The design appears on the flat surface in a foreshortened circular form. The flat surface is adapted for subsequent formation into an arcuate surface bearing the design in relatively undistorted form.
