An embodiment includes a method for net shape forging of a manifold block, comprising: starting with a single bar having a first cross-sectional area, placing a work piece area of the single bar in a die; and upsetting, via longitudinal movement of the single bar, the work piece area of the single bar in the die, wherein the single bar is pressed into the die to reduce its length; whereby the work piece area of the single bar is displaced to an increased cross-sectional area as compared to the first cross-sectional area. Other aspects are described and claimed.

Open containment frame for roller applied deep compression treatment of shaft products

An embodiment includes a method, comprising: applying an overlay material to a portion of a rotatable shaft; directing a pulse of laser energy to contact the overlay material to produce a shock wave; and re-positioning one or more of the portion of the rotatable shaft and the pulse of laser energy to contact the overlay material at different positions to create a laser peened surface on the portion of the rotatable shaft; the pulse of laser energy comprising a pulse sufficient to create the laser peened surface having residual compressive stress to a depth exceeding about 3 mm. Other aspects are described and claimed.

A compact header assembly for connection to a printed circuit board comprises a header housing 20 having a central through opening 22, a pin terminal and carrier strip assembly 24 having a carrier strip 26 which is slidably connected to the header housing 20 via a rail and groove connection and which carries a plurality of pin terminals 28 which are connected to the circuit traces 14, 15 of the printed circuit board 12 and a preassembled wiring harness connector subassembly 30 having a retainer housing 32, a connector body 34 which is connected to the retainer housing 32 and which carries a plurality of female socket terminals 36. The connector body 34 after the terminals 36 are positioned therein is slidably connected to the retainer housing 32 and the retainer housing 32 in turn is then slidably connected into the central opening 22 of the header housing 20 and with the socket terminals 36 matingly engaging the pin terminals 28 when the connector subassembly 30 is connected to the header housing 20.

A filtered electrical connector comprises a selectively plated insulator housing having a plurality of pin terminals and a like plurality of small electrical components. The insulator housing is made of a platable thermoplastic part and a non-platable thermoplasitc part is a two shot molding process. The platable thermoplastic part provides a row of terminal cavities and a predominate portion of the insulator housing surfaces. The non-platable thermoplastic part lines surfaces of the platable thermoplastic part that are adjacent exposed portions of the pin terminals and also partitions portions of the platable thermoplastic part to provide individual mounting sites for the small electrical component associated with each of the terminal cavities. The surfaces of the platable part are plated with a metal coating while the surfaces of the non-platable part are not so that each mounting site comprises a pair of spaced electrical contacts that are connected by conductive paths to their associated conductive terminal cavity and to an electrical shield (ground plane) respectively. The electrical components are attached to the mounting sites so that their spaced contacts engage the respective spaced electrical contacts at the mounting site and individual circuits through these electrical components are completed by inserting the pin terminals into their respective terminal cavities.

Filtered electrical connector and method of making same

An electrical header connector is attached to a printed circuit board by a sheet metal bracket or brackets comprising a body portion that has retaining means at each lateral end in the form of runners that are inserted into narrow longitudinal slots of the electrical header connector and have lock tangs that dig into surfaces of the slots to securely fasten the sheet metal bracket to the electrical header connector. The body portion further including at least one spring clip disposed between the runners that is pushed into a hole of the printed circuit board to attach the electrical header connector to the printed circuit board. The sheet metal bracket may also include means for establishing an electrical ground connection between a ground wire and the printed circuit board.

A male circuit board terminal includes a unitary electrically conductive housing with an outboard section, a core section and an inboard section arranged to provide a sound mechnical connection and electrical connection between the circuit board and a cut electrical lead. The outboard section includes first and second pairs of crimping tabs to respectively connect the terminal to the cut electrical lead and to connect the wire strands from the cut lead outboard of the board through a distance which prevents dewetting of a solder connection between the terminal and the circuit board; the terminal also includes a third pair of crimping tabs on the core section to contain wire strands in the plane of the circuit board at a connection hole therethrough and to provide a positive electrical connection between the strands and conductive plating at the connection hole and a low pressure crimp is provided on the inboard end of the terminal which protects the lock tang and terminal during insertion thereof into the board and wherein the locking tang and terminal are configured to ensure retention of the terminal on the board while defining a solder pocket which completely wets the ends of the wire strands and the section of the wire strands within the plane of the board for providing electrical continuity therebetween.
