    摘要: A circumferential seal for sealing between a rotating shaft and a stationary housing circumscribing the shaft. The seal comprises a stator mounted to said housing and having a radially inward facing carbon portion and a rotor with a ceramic sealing member having a radially outward facing surface in rubbing contact with said carbon portion. The rotor also includes a metal clamping means for mounting the ceramic sealing member to the shaft. The clamping means includes an axial flexible clamping member, and a radial flexible clamping member that together clamp onto a mounting flange of the ceramic sealing member when exposed to the compressive force of a lockup assembly.

    摘要: A T-square apparatus that facilitates intra-operative applications of orthogonal alignment to spinal reconstruction. More specifically, at least one cross member is connected orthogonally to a longitudinal member to assist in aligning the hips and pelvis perpendicular to the longitudinal access of the spine and to assist in positioning of the shoulders parallel to the hips and perpendicular to the spine. The T-square apparatus includes radiopaque markers to allow more accurate estimation of this sometimes difficult to appreciate intra-operative alignment.
