Patent number: 7765665Abstract: A method and apparatus for assembling a fluid conduit assembly and testing the fluid conduit for leaks. Clipping devices support fasteners at a position remote from the conduit. According to the invention the fasteners can be loaded into clip nests provided by the clipping devices while leak testing of the conduit is performed. The performance of these steps simultaneously effectively eliminates the conventional requirement of pre-loading installation fasteners into the leak testing apparatus, and thus reduces the overall time required for the testing and assembly of fluid conduits by approximately one third. If the leak test is successful, all of the fasteners are then moved to the conduits and closed to integrate the conduit assembly.Type: GrantFiled: December 7, 2006Date of Patent: August 3, 2010Inventors: David Burton, Nat Rea

Patent number: 7753351Abstract: The disclosed clamp device for clamping blank pieces may comprise a mounting table, first and second clamping units, positioning units, and lock units. The mounting table is for placing thereon first and second blank pieces. The first and second clamping units have respective clamp plates that are able to be put on the first and second blank pieces while permitting a guided movement of the first and second blank pieces on the mounting table. The positioning units move the first and second blank pieces to establish a positioning of the first and second blank pieces on the mounting table. The lock units apply a given force to the first and second clamp plates to lock the first and second blank pieces.Type: GrantFiled: May 27, 2008Date of Patent: July 13, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Masatoshi Yajima, Shouhei Imai, Norio Kawano, Masamichi Miwa

Patent number: 7735815Abstract: A holding device produces a retaining pressure on a contoured airplane component (40) for holding the component in place when work is performed on the component. For this purpose the holding device (10) comprises a support (11) and at least one holding element (16) connected to the support (11) and projecting from the support (11) for contacting the contoured airplane component (40) in a holding zone. A spacing between a contact area of the holding element (16) and the support (11) is adjustable in accordance with the contour of the airplane component (40) in the holding zone. The adjustment of the position of the holding element relative to the support (11) moves the holding element (16) more or less against the surface contour so that the holding force is applied exactly where needed on the holding zone. A plurality of holding elements can be advanced toward the surface contour to variable extents so that all contact areas together conform to the surface contour.Type: GrantFiled: March 24, 2005Date of Patent: June 15, 2010Assignee: Airbus Deutschland GmbHInventor: Juergen Otten
