摘要： 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.

摘要： Friction stir welding equipment control force spindle for mounting in an orbital head housing uses a coaxial sensor to measure downforce. Simultaneously, an axial electrical actuator is controlled to dynamically correct the axial tool position during the welding, by a direct axial force system control, in order to maintain controlled downforce according to parameters previously set, based on numerical control. The equipment also sets up, monitors and controls spindle rotation speed, welding speed, acceleration speed and downforce using for example closed loop control functions. A laser system may scan the backing surface before welding and correct original tool path, in order to get an offset tool path. A precision alarm system may provide safe welding while preventing the tool from colliding with the backing surface.

摘要： The present invention relates to a bullet (10). More particularly, the present invention relates to a bullet (10) including concentric and sequentially ordered cylindrical fore (22), intermediate (20) and aft (18) portions. The aft portion (18) comprises a cross-sectional diameter about equal to the diameter measured across the rifle landings of the riffled barrel (12) operatively to create a gas pressure build up there-behind while the rifling grooves and lands deform and/or cut the aft portion (18) thereby to impart spin to the bullet (10) about the central axial axis thereof. The intermediate portion (29) comprises a cross-sectional diameter smaller than that of the aft portion (18), which acts as a bearing surface for operatively riding along the rifling lands thereby to inhibit yawing of the bullet (10) while operatively travelling through the rifled barrel (12). The fore portion (22) comprises a cross-sectional diameter smaller than that of the intermediate portion (20) with an annular stamping surface, for operatively providing a clean cut circular hunting wound, located at or near an interface between the fore (22) and intermediate portions (20).

摘要： A piston and cylinder combination driven by linear motor with cylinder position recognition system, including a support structure forming an air gap; a motor winding generating a variable magnetic flow along part of the air gap; a cylinder having a head at one end; a piston connected to a magnet, the magnet driven by the magnetic flow of the motor winding to move inside a displacement path including at least partially the air gap; the displacement of the magnet making the piston reciprocatingly move inside the cylinder; and an inductive sensor disposed at a point of the displacement path of the magnet, such that when the piston reaches a position of closest approach to the cylinder head, the inductive sensor detects a variation in the magnetic field resulting from the corresponding position of the magnet, and generates a voltage signal arising from this magnetic field variation.
