Abstract:
The water jet peening device of the present invention is provided with: a swiveling mechanism for swiveling a spray nozzle in the horizontal direction centered on a positioning member that is positioned at the upper end of an instrumentation tube support; a lift mechanism for raising and lowering the spray nozzle in the vertical direction with respect to the positioning member that is positioned at the upper end of the instrumentation tube support; and a rotation mechanism for supporting the spray nozzle so as to be able to rotate centered on a downward-inclined rotation shaft center on the positioning member end of the vertical direction, disposing a spray port aimed toward the side of the rotation shaft center in a direction that is at a slant from the rotation shaft center, and rotating the spray nozzle centered on the rotation shaft center.
Abstract:
An apparatus for coating the internal surface of a tubular object having an irregular internal surface which comprises a combination of arms which enable the torch to be in the optimal coating position as it moves over and coats the internal surface.

Abstract:
Refractory material is applied to the interior surface of a vessel by advancing a boom carriage on a frame positioned externally of the vessel through an opening in the vessel. The boom carriage supports a collapsed telescoping mast and a nozzle boom. The carriage supporting the mast and nozzle boom is advanced through the opening to an elevated position within the vessel. At the end of travel of the boom carriage, the telescoping mast is pivoted through approximately 90.degree. to a vertical position and the nozzle boom is pivoted to a position perpendicular to the mast. The mast is progressively extended as the nozzle boom is rotated and refractory material is sprayed from a nozzle assembly on the end of the boom onto the vessel interior surface. The nozzle boom is transversely and pivotally movable on the mast to adjust the position of the nozzle assembly to follow the irregular contour on the interior surface as the mast is telescopically advanced or retracted.

Abstract:
A machine for spray coating a rotating irregular shape which moves a spray coating device in three paths to provide constant relative speed; standoff distance; and angular relationship between the spray coating device and surface of the shape to be coated.
