    摘要： A switch (10) comprises a switch housing (11), a plunger (12) located within the switch housing (11), one end of the plunger (12) extending out of the housing (11), the plunger (12) being capable of limited movement relative to the housing (11). An electrical contact (17) is provided on the plunger (12) and is adapted to engage an electrical contact (19, 20) associated with the housing (11) at an outward limit of movement of the plunger (12). A stop (25) is provided coaxially of the plunger (12) for engagement of the end (18) of the plunger (12) at a normal inward limit of movement of the plunger (12). The stop (25) is displaceable axially when a load in excess of a predetermined magnitude is applied thereto by the plunger (12) to permit movement of the plunger (12) beyond its normal inward limit of movement relative to the housing (11).

    摘要： A marine diesel cylinder is lubricated using a lubricant having a total base number (TBN) of at least about 25, comprising an oil of lubricating viscosity and a metal-containing detergent component. Forty to 90 percent of the TBN derived from the metal-containing detergent component is provided by calcium detergent; 5 to 40 percent of the TBN by sodium detergent; and 5 to 45 percent by magnesium detergent. At least 50 weight percent of the total detergent substrate is sulfonate and less than 50 weight percent is monomeric or oligomeric substrate comprising one or more units of alkyl-substituted phenol having an alkyl group of 8 to 14 carbon atoms. The lubricant is useful when the marine diesel engine is fueled with a liquid fuel containing at least 2 ppm vanadium.

    摘要： An apparatus for mounting an object precisely in a specific plane. An object is mounted on small support points rather than flat pads or other flat surfaces. The support points are stiff but not completely rigid. Exactly four support points are used. Mechanical forces are sufficient to slightly compress the two higher support points on a diagonal and to slightly compress the object so that the object presses against all the support points, with a higher amount of compression for one pair of diagonal points relative to the other two points. In an example embodiment, the support points are formed at the intersection of curved surfaces or at the intersection of multiple planar surfaces. In a specific example embodiment, the points are formed at the intersection of cylindrical surfaces. The points are fabricated by a cylindrical cutting bit that has partial-cylinder grooves formed circumferentially in the bit. The outer surface of the bit is used to mill two intersecting planes, and the grooves result in cylindrical surfaces intersecting at the same angle as the intersecting planes. The resulting support points are true singular points, but with limited compressibility because of the shallow angle of the material just below the points.

    摘要： Grounding technology is provided for a short-wire, circuit board test fixture. As a result of the grounding technology, the ground between a circuit board test system and a circuit board under test can be reliably controlled. The grounding technology provides testing at extremely higher speeds by minimizing ground bounce. An internal ground plane is situated in the test fixture. Pursuant to one embodiment of the invention, a coax assembly at ground potential surrounds critical signal paths between the internal ground plane and an alignment plate situated at the bottom of the test fixture. Either a conductive alignment plate or a conductive ground comb affixed to a non-conductive alignment plate is implemented to permit conduction of the ground signal between the board test system and the coax assembly. In another embodiment, an array of ground personality pins provides conduction of the ground signal between the internal ground plane and the board test system. The ground personality pins are clustered around critical signal paths to control impedance.
