A bone resection tool for resecting an end of a bone along a surface having a curvature comprises a guide, a cutting tool and a track follower. The guide is configured to be removably attached in a fixed position to the end of the bone. The guide is configured to include a track exhibiting a curvature generally corresponding to the curvature of the surface to be resected in the bone. The cutting tool includes a cutting face. The track follower is configured to couple to the cutting tool and cooperate with the track to facilitate reciprocation of the cutting tool relative to the guide to induce the cutting face to resect the bone along the surface having the curvature. A method for cutting a bone along a curved surface conforming to the curvature of a curved surface of the underside of a prosthetic component comprises the steps of incising the tissue surrounding the surface of the bone, positioning a guide alongside the surface of a bone to be cut, affixing the guide to the bone, interconnecting a cutter having a cutting face with the guide, maintaining the cutting face generally parallel to the tangent of the curved surface and traversing the cutting face along the bone while guiding the cutter along the track. The tissue incision incises the tissue surrounding the surface of the bone to be cut in a minimally invasive fashion. The positioned guide includes a track configured to assimilate the curvature of the curved surface of the underside of the prosthetic component.

The present invention provides a method of joining dissimilar materials, particularly a non-ferrous component to a ferrous component to form an assembly. In an overlapping configuration, the parts are held together under a clamping force while a self-piercing rivet is driven through the assembly by a welding electrode. The rivet pierces and passes through the non-ferrous component and then at least into contact with the ferrous component to thereby form a mechanical interlock. An electrical current is then applied to this mechanical retention to melt a portion of the rivet as well as a portion of the ferrous metal in the joining region. The flow of electrical current is then stopped after several welding cycles where the now melted material is allowed to solidify upon cooling, thereby forming a weld.

In a tunnel-like region of a sterilizing tunnel, containers are advanced by means of a conveyor device. For sterilization, a heated air flow oriented vertically in the region of the containers is used, which is generated by means of a fan and a heater.
