Lewis L Van Kuiken, Jr

A system for supplying blasting media to a media blasting system in which a pair of pressure pots or pressure chambers are provided in which the blasting media is introduced for dispensing the media to conduits leading to blasting guns. The media supply valves and air supply valves are controlled by a cam shaft assembly. Further, a metering hopper having a media supply valve is provided between the storage hopper and upper pressure pot or chamber. The media and air valves are operated in timed sequence as determined by the cam shaft assembly.

System for supplying blasting media to a media blasting system

A method for treating an article having rust corrosion characteristics in which the article is dry-blasted by the propulsion of glass beads to compressibly peen the surfaces of the articles and thereafter preferably applying a protective coating to the peened surface. The glass beads are preferably blasted against such surfaces by pneumatic propulsion and are of a mesh size falling within the range of 70-140 mesh. Also, preferably the intensity of the glass beads striking the surface of the article is controlled so than an Almen test strip 'N' subjected to the same blasting procedure shall show an Almen gauge reading of 0.005-0.007 inches. This invention encompasses an article treated specifically for the purpose of corrosion protection employing the above method.
