  • Patent number: 9417155
    Abstract: A calcareous deposit wipe-test apparatus and method. The apparatus includes a motor, frame, with the motor and the replaceable cartridge attached to the frame. The replaceable cartridge includes a calcareous deposit roller for growing calcareous deposits thereon, which typically cause abrasive wear. The wipe-test apparatus also includes a trough which is filled with seawater. The frame positioned in the trough, and shaped so that when positioned in the trough, the motor is perched above in a dry location and the replaceable cartridge is below, at least partially submerged so that the calcareous deposit roller simulates shipboard wet operating conditions. The apparatus and method evaluates the removal of the calcareous deposits under shipboard working conditions.

  • Patent number: 7971303
    Abstract: A scraper tool for removing material such as surface treatments, metal coatings, and other material layers from an edge region of a metal work piece where they could potentially contaminate a nearby weld. According to one embodiment, the scraper tool includes a body having a base portion and a tab portion, and several scraping elements attached to the base portion. During operation, the scraping elements scrape one or more surfaces of the edge region so that the depth to which the scraping element engage the metal work piece is generally affected by the amount of rotation of the scraper tool about a pivot axis.

  • Patent number: 6481075
    Abstract: A peeling machine through which a rod workpiece is moved along a workpiece axis has upstream and downstream guides centering the workpiece on the axis is and axially flanking a rotary scraper engaging the workpiece and carried on an upstream end of a scraper tube coaxially surrounding the downstream guide and rotatable about the workpiece axis. The downstream guide has a stationary tubular housing extending coaxially in the rotatable scraper tube, a plurality of shafts pivotal in the tubular housing about respective guide axes angularly spaced about the workpiece axis, and respective axially elongated guide bars fixed on the shafts, extending axially therealong generally a full length of the scraper tube, and projecting radially of the guide axes therefrom. Guide elements—rollers or blocks—carried on the bars are engageable radially of the workpiece axis with the workpiece.
