A knee joint prosthesis includes femoral and tibial components, a bearing and a control arm. The bearing includes an inferior surface in sliding bearing engagement with the tibial component and a superior surface in articular bearing engagement with the femoral component. A notch extends into the posterior end of the bearing and a groove extends anteriorly from the notch in the inferior surface of the bearing. The posterior portions of the femoral component define a cam box having medial and lateral walls and a cam extending therebetween. The control arm is slidably engaged in the groove of the bearing and pivotally engage on the tibial component. The control arm further includes a post that extends into the cam box. The post includes a cam surface that engages the femoral cam to generate roll back of the femoral component on the bearing during flexion. Roll back substantially avoids climb of the femoral component on the bearing during flexion and hence reduces shearing forces on the post.

A prosthetic replacement knee joint includes a tibial component, a femoral component, a bearing and a control arm. The tibial component has a superior bearing surface and a conical recess extending into the superior bearing surface. The bearing has an inferior surface slidably engaged with the superior surface of the tibial component and formed with a dovetailed groove therein. The bearing also has a concave superior surface. A notch extends into the posterior extreme of the bearing. The femoral component has a pair of convex arcuate condyles in articular bearing engagement with the superior surface of the bearing. The femoral component also includes a posterior notch having a minor medial-lateral width at the inferior surface of the femoral component and a major width at more superior locations on the femoral component. The control arm has a conical bearing rotatable positioned in the conical recess of the tibial component. The control arm further has a dovetail guide slidably engaged in the dovetail groove of the bearing.

A physical vapor deposition apparatus and process are provided for providing a highly smooth shiny coating to a substrate. The apparatus includes a chamber with a fixture for mounting the components to be coated. The fixture is arranged such that the surfaces to be coated define a âdark sideâ that faces away from the source of ion bombardment. With this arrangement, heavier multiple ions will travel past the surface to be coated. Lighter single ions will be drawn more readily to the oppositely charged surface to be coated, and hence will undergo a non-linear travel path for deposition onto the component.

In a winding assembly for winding web rolls, an enveloper assembly is used to initiate winding of a web stream onto a pre-formed core or to initiate winding of a core-forming substrate into an in-line core. The enveloper assembly comprises a first support arm operatively coupled to a second support arm; a third support arm operatively coupled to the second support arm; and an enveloper roller operatively coupled to the third support arm. The enveloper roller is movable along a cylindrical surface from a first position to a second position. The enveloper assembly accommodates a wide range of core diameters. For winding non-adhesive web streams, a tail tucker can be used in conjunction with the enveloper assembly to initiate winding. In conjunction with apparatus for inserting core-forming substrates or adhesive tabs onto a web, the winding assembly can perform high-volume, streaming production of wound web rolls.
