Abstract: A graft or prosthetic element suitable, e.g., for replacing a tendon or ligament is fastened in a bone tunnel or blind opening with the aid of a fastener. In a first step, the graft or prosthetic element is press-fitted in the tunnel or opening by forcing the fastener into the opening or by positioning the fastener in the opening and then expanding it, wherein the fastener is in contact with the graft or prosthetic element and with the bone wall of the tunnel or blind opening. In a second step, the fastener is anchored in the bone wall of the tunnel or blind opening with the aid of a liquefiable material which is liquefied in the vicinity of the bone wall where it is in contact with the fastener and by making the liquefied material penetrate into the bone wall.

Abstract: An apparatus and method for treating a plastic molded article. The apparatus includes a treatment chamber that can be closed and temperature-controlled. A vapor generating unit generates vapor of a treatment liquid. A fluid connection between the treatment chamber and the vapor generating unit feeds vapor to the treatment chamber and returns condensate back to the treatment chamber. A pressure equalizing device transfers waste air at atmospheric pressure and equalizes pressure with the atmospheric pressure during treatment. The pressure equalizing device retains vapor and prevents vapor from escaping into the atmosphere. A vapor phase is generated by heating a treatment liquid to its boiling point. The treatment liquid includes a solvent that dissolves or solubilizes the plastic. The article is exposed to the vapor phase for a predetermined time and removed from the vapor phase. Residual treatment liquid present on the article is removed.

Abstract: In a method for scanning the surface of metallic workpieces, during scanning, a welding torch with a consumable welding wire is moved over and towards the workpiece surface, until contact of the welding wire with the workpiece is detected, and the welding wire is subsequently moved away from the workpiece. Before scanning, slag-removal is carried out to remove slag at the welding wire end, wherein the welding current is lowered to a minimum, and the welding wire is moved cyclically with a rapid recurrent forward/backward movement over a specified path length toward the workpiece, and by a smaller distance away from the workpiece, until a short circuit between the welding wire and the workpiece is detected, whereupon slag-removal is ended, and upon the detection of no short circuit, slag-removal is repeated, and upon the detection of several short circuits one after the other, slag-removal is ended.
