Abstract: An apparatus for extraction of osseous tissue is disclosed. The apparatus includes a fixed portion and a clamp oriented along a generally central area of the fixed portion. The apparatus includes a first bone cutting device and a second bone cutting device coupled to the fixed portion and oriented around the clamp. The first bone cutting device and the second bone cutting device are coupled to the fixed portion using respective joints that accommodate orientations of the first bone cutting device and the second bone cutting device relative to the fixed portion along different horizontal and vertical axes. The clamp is configured to engage a first bone portion during a surgical procedure.

Abstract: Various embodiments of a non-metal retractor device for retracting an incision and retaining a shunt are described herein.

Abstract: The invention relates to a method for wrapping a long or round part, for example a steel part, for instance in the form of a steel strip coil, a steel wire roll or a round steel part such as a roller bearing ring, the steel part being wrapped in a stretch film, in particular a plastic stretch film, in a helical and covering manner. In order to realize a short term wrapping of a long or round part, irrespective of its material properties, and as a reliable transport protection the invention proposes that a strip material which is significantly more resistant than the stretch film and has an adhesive coating on the side facing the stretch film is wound over the stretch film likewise in a covering manner.

Abstract: A process and device for the laser treatment of the internal surfaces of hollow bodies such as engine blocks with cylinder bores which consist of the matrix alloys such as a light-metal or aluminum, wherein a wear-resistant coating is applied to the working surfaces of the pistons within the cylinder. A probe enters the cylinder and includes the laser beam which produces a beam spot on the internal surface of the cylinder and applies an alloying powder at the focus of the spot using a continuously conveying protective gas. The probe is displaced along the axis of the cylinder and simultaneously rotated while the alloying powder is melted in the spot of the laser beam to a depth sufficient to form a wear-resistant coating which will not break loose during the normal operation and life of the engine block. The engine block can be fixed in a stationary position while the probe or probes move simultaneously within the cylinders to apply the hardened surface coating.

Abstract: A bundling machine comprising a bundling material supply roll moving along a circular path and a gripping device for engaging and cutting the bundling material, such gripping device having two beams able to be actuated to clamp and cut the bundling material, and of which one beam is able to be swung in relation to the other beam, such beams being guided by a carrier for performing a movement into and out of the bundling plane and a carriage is able to be moved in direction normal to the direction of motion of the carrier, one such beam being pivotally mounted on the carriage.
