Abstract: A surgical instrument bolt for use with an orthopaedic prosthesis inserter includes a bolt head and a bolt shaft that extends away from the bolt head. The bolt shaft includes a threaded end and a shank located between the threaded end and the bolt head. The bolt shaft also includes an inner surface that defines an axial passageway that extends through at least a portion of the bolt shaft. In some embodiments, the axial passageway may extend completely through the bolt shaft and bolt head or may be embodied as a blind passageway in other embodiments.

Abstract: An orthopaedic surgical instrument includes an insertion tool having a threaded end configured to engage an acetabular cup. A gauge is provided including a pair of clamp arms configured to engage the insertion tool to secure the gauge to the insertion tool. A clamping lever is rotatable to move the clamp arms into engagement with the insertion tool. A visual indicator is configured to indicate a predetermined orientation of the insertion tool relative to a patient's body.

Abstract: A method of reproducing a central axis of a femoral neck prior to resection during an implantation process includes the step of attaching a frame to the acetabulum of a patient, wherein the frame includes first and second movable arms and a lockable swivel bearing. The method further includes the steps of orienting and locking the swivel bearing in position and utilizing the position of the swivel bearing to position acetabular instrumentation to match a planned acetabular implant orientation.

Abstract: An extrusion resistant ring that is radially expandable and contactable to accommodate the relative movement of two joined bodies relative to each other. The extrusion resistant ring in combination with an elastomeric diaphragm provides a high pressure seal for down-hole oil drilling apparatus.

Abstract: A known gland 11 includes first and second members 12 and 13. Prior art seals 33 (FIGS. 1A and 1B), 40 (FIG. 2A and 2B) or 50 (FIG. 3) can be used to seal the gland 11. Also, a novel, double acting, over center cone, articulating compression seal 60 (FIGS. 4 and 5) can be used to seal the gland 11. The seal 60 includes a base 61, an articulating compression arm 62, and a rocker 63. The arm 62 is connected to the base 61 at one hinge region 73 and to the rocker 63 at another hinge region 83. The articulating compression arm 62 is cone shaped, and the cone inverts as the seal 60 is displaced from a relaxed position (FIG. 4) to a sealed position (FIG. 5). The rocker 63 extends radially and longitudinally in the relaxed position and extends longitudinally in the sealing position.

Abstract: A hollow seal for use in sealing between relatively movable first and second panels, such as between a fixed window panel and a slidable window panel of a rear window of a pick-up truck or the like. The hollow seal has an internal geometry that supports an outside layer or portion of the seal under pressurization to prevent leakage and seal blowout. The outside portion is shaped to provide a pair of laterally spaced-apart sealing lips that have a pressure-activated sealing geometry for tight sealing against the panels when under pressurization.

Abstract: A multi-piece seal preferably for a sealed joint of a fuel tank assembly. An outer member has in an uncompressed state a cross-sectional shape defined by substantially semi-circular-shaped portions that define a substantially semi-circular channel and that terminate in free ends. An inner member is disposed at least partially in the channel of the outer member and has in an uncompressed state a substantially round cross-sectional shape. Preferably, the outer member is composed of a permeation-resistant material, and the inner member is composed of a relatively less expensive material capable of better elasticity performance at relatively lower temperatures compared to the outer member. The outer member preferably has lobed ends and the inner member preferably includes one or both of a stress-relieving feature or an orientation feature to orient the inner member relative to the outer member.

Abstract: A ring seal includes a sealing ring including an asymmetric body portion having axially-opposed and radially-offset seal beads. The ring seal may also include a reinforcement ring carried at least partially in the sealing ring to distribute load across the seal beads. The ring seal may further include a skirt depending generally axially from the body portion and defining an inner diameter of the sealing ring and preferably having frusto-conical cross-sectional shape.

Abstract: Seal ring or other construction for providing a fluid seal intermediate a pair of opposing surfaces. The seal includes a body formed of a resilient material which is configured as having a series of projections which extend radially outwardly from lateral surfaces thereof such that the seal is self-retaining in a dovetail or other undercut groove.

Abstract: Composite seal or gasket for inhibiting the release of a volatile organic compound such as fuel. The seal includes a deformable portion interconnected to a vapor barrier portion via a mechanical or adhesive interlocking connection. The deformable portion can be formed from an elastomeric material. The vapor barrier portion can be formed from a wide variety of materials that inhibit permeation of the organic vapor. Examples of the materials for the vapor barrier include ductile metals, plastic polymers, and fluoroplastic polymers. The gaskets and seals can be, but are not restricted to be, used between the connections of the components in an automotive or consumer product fuel system.

Abstract: A compact closure assembly for a capless filler tube for a fuel tank includes a housing having a passageway extending therethough for receiving a fuel filler nozzle, and a door moveable from a first position sealing the passageway to a second position permitting insertion of the fuel filler nozzle into the passageway. The door is contoured such that when in the second position, the outer surface of the door is generally concentric with a wall of the housing about a longitudinal axis of the passageway. Accordingly, much of the additional space found in conventional closure assemblies that is needed for accommodating the flat door in the open position can be eliminated.

Abstract: A bellows structure (10) comprises a first end (50), a second end (52), and a wall (54) extending axially therebetween. The wall (54) includes a plurality of lobe portions (80) and furrow portions (82) connecting adjacent lobe portions (80). The furrow portions (82) are radially recessed relative to the lobe portions (80) when the bellows wall (54) is in an unstressed state. To increase the volume of the bellows chamber (56) in response to fluid condition changes, the furrow portions (82) unfold and move radially outward.
