Abstract: An arrangement for locking a metal tube to a hose fitting in which the end of the metal tube is flared to form a generally conical tube end, and the conical tube end is inserted into a fitting to seat against an opposing conical shoulder. The portion of the fitting surrounding the tube is then plastically deformed around the tube firmly and sealingly to grasp the tube, but without scarring a corrosion resistant coating on the tube. A plurality of barbs preferably are formed on the radially outer surface of the flared end of the tube for engaging the fitting when the fitting is crimped over the flared end of the tube and thereby preventing rotation of the tube with respect to the body of the fitting. The other end of the fitting may be crimped or otherwise secured to a constituent part such as a fluid hose.

Abstract: A framework of magnet pods and beams or strongbacks can be quickly and easily assembled to plug a leak in a ferromagnetic container wall. The magnet pods are located on either side of the leak. One or more beams extend between the magnet pods. Each magnet pod has a yoke with plural holes therethrough. The yoke loosely receives the beam. Each beam has lines of holes therethrough all along the beam length. The plurality of holes in the yokes and beams simplifies the alignment of at least one set of holes between the yoke and beam, wherein a pin is inserted to couple the beam to the magnet pod. A clamp is pinned to the beam so as to be adjacent to the leak. The clamp is tightened to exert removable pressure on a patch over the leak.

Abstract: The method makes it possible to form a stator of an electric motor by means of a multiple-slide press (21, 22, 23). The starting point is a bundle consisting of rectilinear segments of sheets obtained by stamping and welded. The stator is formed by means of four successive operations carried out by four groups of slides of a multiple-slide press and corresponding dies. The cylinder formed is subsequently welded along its joining generatrix and is calibrated in a hydraulic press.

Abstract: An armature for a selectively engageable and disengageable coupling and a method of making the armature are provided. The armature includes a substantially annular body that is disposed about a first axis. The body may be formed by stamping or fine-blanking. One side of the body is hardened through a nitriding process. A grinding wheel is then applied at an angle to the same side of the body along a diametrical line of the body extending perpendicular to the first axis. As a result, the body is configured so that the thickness of the body increases as the distance from the diametrical line increases. In particular, the thickness of the body varies along each cross-section taken along the line from a minimum thickness at the innermost portion of the cross-section to a maximum thickness at the outermost portion of the cross-section. The inventive armature reduces galling, and the resulting noise, that occur during burnishing of couplings incorporating the armature.
