Abstract: An orbital cleaning assembly, including: an axis of rotation; a housing; a drive assembly at least partly disposed within a space formed by the housing; a tube assembly at least partly disposed within the space and including a tube including: a first end arranged to connect to a source of fluid and a flexible portion including a second end of the tube. The second end is arranged to receive a nozzle. The drive assembly is arranged to position the second end at a radial distance from the axis of rotation and flex the tube assembly such that the second end traverses a path about the axis.

Abstract: A fastening device is provided which is a variation on the conventional nut and bolt. The bolt has a longitudinal axis and threading helically affixed thereon along the longitudinal axis. A nut having a bore extending therethrough is provided. The bore of the nut has a greater diameter than the diameter of the bolt so the bolt can extend through the bore. An array of wire bristles are affixed within the bore so as to form a brush. The wire bristles extend inwardly from the bore and are constructed and arranged of the correct size, length and stiffness to guide the bolt within the bore and to restrain the bolt within the bore as required. A variety of applications of the wire brush nut are disclosed, including a bolt capture device and a test rig apparatus.
