Abstract: A dynamic prosthetic vertebral body for use in a cavity left by resection of a natural vertebral body and adjacent intervertebral discs. The prosthesis includes a pair of rigid housings joined by a connecting structure that is operable to shift the housings apart into supportive engagement with the healthy vertebral bodies adjacent the site of the resected body. Anchoring pins project outwardly in axial directions from the respective housings for secure fixation to the healthy vertebral bodies. Within the chamber of each housing is a rigid suspension plate surrounded by an elastomeric suspension medium, and the suspension plates of the two housings are joined by the expandable connecting structure. The relative sizes of the suspension plates and the chambers in which they are received allow limited movement of the housings, resulting in a prosthesis that provides the required support but also mimics the dynamics of a normal vertebra and adjacent discs.

Abstract: A vehicle wheel assembly comprises a detachable wheel mounted on a radial wheel mounting flange using a single wheel fastener and a conical disc spring to secure the wheel to the wheel mounting flange.The conical disc spring is deflected to a preselected compressed state by the fastener to exert a predetermined axial clamping force uniformly along an annular region of contact between the wheel and the disc spring and to resiliently pre-load the wheel bearings. A lock prevents the single fastener from working loose.

Abstract: A wheel cover with a plurality of axially extending resilient prongs the free ends of which extend through prong receiving holes in the mounting bolt circle area of a disk of a vehicle wheel. The prongs have a cam surface adjacent the free edge thereof which engages the inner edge of the prong receiving holes to abut the free ends of the prongs with the mounting surface of a hub on which the disk is secured to firmly and tightly retain the wheel cover on the wheel.
