Abstract: The invention relates to pliers for changing the distance of two activation surfaces of a connection or fitting for conduits. The change of the distance correlates with an elastic or plastic deformation of at least one component of the fitting including a radial crimping process. The inventive pliers comprise two hand levers linked by a transfer mechanism with two spreading jaws. According to the invention, a closing movement of the hand levers results in a spreading movement of the spreading jaws. Such spreading movement of the spreading jaws is used for plastically deforming at least one of the components of the connection by a radial crimping process.

Abstract: A high pressure pump includes a pump housing. A piston rod located within the pump housing defines a plurality of pump cavities and a plurality of piston cavities. Movement of the piston within the piston cylinder pumps the fluid from the piston cavities out of the high pressure pump. The continuous pumping of HWBF from the pump housing provides fluid at a relatively constant flow and pressure. The HWBF pressure is also at a higher pressure than traditional single stage high pressure pumps can provide.

Abstract: A device for producing a pattern onto a work piece includes a die, an electromagnetic actuator and a base. The die includes a patterned surface, and the patterned surface includes a pattern. The electromagnetic actuator includes an plate body, a convex part and a strip unit connected to the plate body. The electromagnetic actuator is disposed in the base. When the electromagnetic actuator is activated while a work piece is being positioned between the patterned surface and the electromagnetic actuator, an inductive current is generated on the work piece by the electromagnetic actuator, and then a repulsive force is generated between the electromagnetic actuator and the work piece. The repulsive force causes the work piece to adhere to the patterned surface, forcing the work piece to deform against the patterned surface and to take on the shape of the pattern.

Abstract: A non-planar sputter target having differing crystallographic orientations in portions of the sputter target surface that promote more desirable deposition and density patterns of material sputtered from the target surface onto a substrate. A closed dome end of the sputter target is comprised of a first crystallographic orientation and sidewalls of the sputter target are comprised of a crystallographic orientation different from that of the dome. The sputter target is formed, preferably by hydroforming or other metal working techniques, in the absence of annealing. The hydroforming manipulations result in the different crystallographic orientations while minimizing, or ideally omitting, the application of heat. Quick and cost effective non-planar sputter targets that are easily repeatably producable are achievable as a result.

Abstract: The invention presents method and apparatus for forming of large thin panels and similar parts having integral stiffeners at one side of a board. The method includes progressive forming of preheated billets into sculptured dies of corresponding length and width by a forging die of substantially identical width and short length with slightly inclined and flat forging surfaces providing a smoothly convergent working zone, and a periodical transfer of the sculptured die into the working zone between successive strokes of the forging die. Control of the material flow is performed by selection of a ratio of the working zone length to the billet thickness, variable contact friction at both dies and application of additional compressive forces to the billet at ends of the working zone. For semi-continuous processing of very long parts, the sculptured die is composed by plurality of sectioned elements.
