Abstract: The removal of a deep bore pattern (14) from a sand mold is facilitated by exerting a force on the sand (12) within the bore (16) to break the bond between the sand and the internal surface of the pattern. The pattern (14) is supported on a pattern plate (18) having an aperture (20) in line with the bore (16). A stripper block (22) is slidably received in the aperture and can extend into the bore. A fixed back plate (24) is supported on the pattern plate, and a compression spring (26) is positioned between the stripper block (22) and the back plate (24). As sand is packed into the mold, and hence the bore, under pressure, the stripper block is forced out of the bore against the spring. When the pressure is removed to allow the pattern to be withdrawn, the spring exerts a force on the stripper block causing it to move back to its initial position, thus breaking the sand free from the inside surface of the deep bore.

Abstract: A method of and apparatus for chemically depositing a metal onto a substrate in the presence of a rapidly flowing chemical-depositing solution furnishing the metal. A narrow light beam is directed onto the substrate and intercepted by a localized area thereon to activate an interface between the area and the flowing solution. The metal in the solution is thereby chemically deposited on the localized area. The beam and the substrate are relatively displaced to successively shift the area of interception of the beam until a desired surface region on the substrate is rapidly deposited. Preferably, the thickness of the solution passing rapidly and traversed by the beam incident on the localized area is limited not to exceed a preselected dimension. The apparatus preferably comprises a mirror for reflecting the beam from a source thereof which is fixed in position onto the workpiece and a drive unit for translationally displacing the mirror to achieve the required displacement of the incident beam relative to the substrate. A lens is disposed in the optical path for the beam and the position thereof is controlled to maintain its focal plane to be coincident with the beam-intercepting localized area.
