    • Friction stir welding (FSW) processes, systems and the resulting friction stir welded components are disclosed whereby first and second workpieces are welded to one another using a first workpiece having mutually orthogonal structural components and a junction region therebetween which defines a bearing surface of predetermined geometry. A shoulder of a FSW tool may be brought into bearing contact with the bearing surface so that a pin extending from the shoulder of the FSW tool may be advanced into and through the one structural component of the first workpiece at an angle relative thereto so as to thereby form a friction stir weld region between the first and second workpieces. Some preferred embodiments will provide a bearing surface which defines an arcuately concave geometry, in which case the shoulder of the FSW tool defines an arcuately convex geometry conformably mateable with the bearing surface. According to other preferred embodiments, the bearing surface defines an arcuately convex geometry, in which case the shoulder of the FSW tool defines an arcuately concave geometry conformably mateable with the bearing surface. According to yet other preferred embodiments, the bearing surface and the shoulder of the FSW tool are each planar.
    • 公开了摩擦搅拌焊接(FSW)工艺,系统和所产生的摩擦搅拌焊接部件,由此使用具有相互正交的结构部件的第一工件和它们之间的接合区域将第一和第二工件彼此焊接,从而限定了预定几何形状的轴承表面 。 可以将FSW工具的肩部与支承面承载接触,使得从FSW工具的肩部延伸的销可以相对于第一工件的一个角度前进并穿过第一工件的一个结构部件,以便 从而在第一和第二工件之间形成摩擦搅拌焊接区域。 一些优选实施例将提供限定弓形凹形几何形状的支承表面,在这种情况下,FSW工具的肩部限定了与支承表面一致地适配的弧形几何形状。 根据其它优选实施例,支承表面限定了弧形凸起的几何形状,在这种情况下,FSW工具的肩部限定了与支承表面一致地适配的弓形凹形几何形状。 根据其他优选实施例,FSW工具的支承表面和肩部都是平面的。

    • The present invention relates to a bullet. More particularly, the present invention relates to a bullet including concentric and sequentially ordered cylindrical fore, intermediate and aft portions. The aft portion comprises a cross-sectional diameter about equal to the diameter measured across the rifle landings of the riffled barrel operatively to create a gas pressure build up there-behind while the rifling grooves and lands deform and/or cut the aft portion thereby to impart spin to the bullet about the central axial axis thereof. The intermediate portion comprises a cross-sectional diameter smaller than that of the aft portion, which acts as a bearing surface for operatively riding along the rifling lands thereby to inhibit yawing of the bullet while operatively travelling through the rifled barrel. The fore portion comprises a cross-sectional diameter smaller than that of the intermediate portion with an annular stamping surface, for operatively providing a clean cut circular hunting wound, located at or near an interface between the fore and intermediate portions.
