Abstract: A plate segment for a reciprocating pump power end frame assembly, the power end frame assembly having a pair of end plate segments and at least one middle plate segment disposed between the end plate segments. The plate segment consists of the middle plate segment or one of the pair of end plate segments and includes a plate having a front wall, a rear wall, a top wall, a bottom wall and a pair of sidewalls and at least one opening forming a bearing support surface, the opening extending through the plate. The plate segment further includes at least one extension extending from at least one of the sidewalls of the plate at a position to align with and contact a corresponding extension on an adjacently positioned plate.

Abstract: An interconnection element is provided for conductive interconnection with another element having at least one of microelectronic devices or wiring thereon. The interconnection element includes a dielectric element having a major surface. A plated metal layer including a plurality of exposed metal posts can project outwardly beyond the major surface of the dielectric element. Some of the metal posts can be electrically insulated from each other by the dielectric element. The interconnection element typically includes a plurality of terminals in conductive communication with the metal posts. The terminals can be connected through the dielectric element to the metal posts. The posts may be defined by plating a metal onto exposed co-planar surfaces of a mandrel and interior surfaces of openings in a mandrel, after which the mandrel can be removed.

Abstract: A welding stud apparatus and method of manufacturing a welding stud are disclosed. The welding stud has a weld end constructed to be welded to a workpiece that has at least one recess formed therein. The recess decreases an effective arc area of the weld end to localize a current therethrough and increase the efficiency with which the welding stud can be welded to a workpiece.

Abstract: A welding apparatus is presented that includes a post-firing detection system and control connected to communicate with the post-firing detection system such that a stud welding gun is prevented from activation if a recently fired welding stud remains connected to the stud welding gun.
