Abstract: An alignment cam pin system is provided. The system includes an alignment pin having a distal end and a proximal end. The alignment pin has a first flange at the proximal end, a cylindrical press fit surface abutting the first flange, and a threaded extension extending from the cylindrical press fit surface. An alignment pin sleeve is provided, which includes a sleeve body and a second flange, wherein the sleeve body includes internal threads configured to mate with the threaded extension. The cylindrical press fit surface of the alignment pin is configured to be press fit into an alignment hole of a vehicle's suspension component, such as a control arm, and the sleeve body of the alignment pin sleeve is configured to be threaded on the threaded extension of the alignment pin such that the alignment pin does not fall out of the alignment hole during vehicle use.

Abstract: An improved pull-up bolt assembly adapted to be used for supporting a high-weight structure to a hinge component using an opening or recess in the high-weight structure, the bolt assembly having a pull-up bolt member, a nut component, a tapered member, and an expandable friction member, where the improvement includes one or more threads helically disposed about the expandable friction member, the one or more threads each having a height, a width and a helical angle.

Abstract: A pull-up bolt assembly for frictionally supporting a high-weight structure to a hinge component using an opening or recess in the high-weight structure.

Abstract: A device to mount a control lever to a bicycle handlebar includes a bracket, an expanding bolt, and a fixing member. The bracket is configured to be connected to the control lever and includes an inlet opening with a center axis, a first tapered portion extending along an axial direction, and at least one tapered outer serration formed on the first tapered portion. The expanding bolt includes a tubular portion and a second tapered portion extending along the axial direction. The tubular portion includes an outer threaded surface. The fixing member is disposed on the tubular portion of the expanding bolt. The first and second tapered portions are configured to operate so as to push the fixing member against an inner surface of the bicycle handlebar when the device is mounted to the bicycle handlebar.

Abstract: A clamping nut suitable for co-operating with a threaded shank of an osteosynthesis appliance, the nut including an annular body and a tapped bore for cooperating with the threaded shank. The annular body is provided with a structure which enables turning the body and with a transverse bearing face. The osteosynthesis nut further includes a ring mounted in a housing of the annular body which is provided internally with the tapped bore, and which cooperates externally with the annular body.

Abstract: A securing device of the expandable boss or grommet type, for securing a member to a support plate, has an expandable boss of a resiliently deformable material extending through the support plate. A fixing bolt extends through the expandable boss and is screwed into an expander nut, the fixing bolt having a head which bears through a head ring on the member to be secured, and the expandable boss including a shouldered head.

Abstract: The present invention relates to an infiltrated ferrous powder metal part containing certain additives, yielding a part having improved dimensional control during infiltration and uniform and predictable distribution of dynamic properties within a given group of commonly manufactured parts.

Abstract: A dual thrust anchor shell assembly for use with mine roof bolts or rock bolts include first and second opposed pivotal upper wing elements and first and second opposed, pivotal lower wing elements disposed about a mine roof bolt between a movable upper nut and a fixed lower nut so that tightening of the roof bolt forces the upper wing elements downward toward the lower wing elements. The upper wing elements each have a plurality of sloped camming surfaces. The lower wing elements also each have a plurality of sloped camming surfaces that engage camming surfaces of the upper wing elements as the roof bolt is tightened. Tightening of the roof bolt first causes the upper wing elements to pivot outward and dig into the walls of a roof bolt hole, anchoring the upper wing elements. Further tightening of the roof bolt causes a roof plate to be drawn tightly against the mine roof, binding strata of the mine roof and reinforcing the mine roof.
