| 20110226281 | METHOD OF REMOVING MATERIAL FROM A SURFACE OF A METAL WORK PIECE - A method of 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, a 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. | 09-22-2011 |

| 20080209974 | Metal Blank with Binder Trim Component and Method - A metal blank that includes a binder trim component having at least one cut edge with a non-linear section. The creation of the non-linear section simultaneously forms a corresponding section in a binder trim component of an adjacent metal blank so that binder material can be shared therebetween. This reduces the amount of scrap metal, as the binder trim component is subsequently cut off and discarded. Furthermore, the non-linear section can include one or more strategically placed formations, such as projections, recesses, flat sections, etc., that cause it to be non-uniform along its length and to be specifically tailored to the manufacturing requirements of the part being formed. | 09-04-2008 |

| 20090096687 | METHODS AND APPARATUS FOR HIGH PERFORMANCE STRUCTURES - Methods and apparatus for components according to various aspects of the present invention operate in conjunction with reaction bonded silicon nitride (RBSN). In one embodiment, a missile radome comprises a wall defining the radome body, including a base and a tip. The wall may comprise a core and one or more skins adjacent the core, such as in a sandwich configuration. The core and the skins may have different densities. The radome wall may be configured to transmit wideband RF signals. The RBSN may be extruded to form the radome. | 04-16-2009 |
