Abstract: The invention is based on a method for detecting slip in the driving of generator or starter-generator systems. The alternators of these systems are equipped with electronic control components such as pulse-width-modulated inverters or rectifier bridges. The drive torque of the alternator is transferred to this by means of a belt drive of an internal combustion engine. When slip is detected in a comparison step (3), to which speed-dependent input variables (1, 2) are forwarded, the maximum transferrable drive torque is determined in a torque limiting step (18, 20), and a closed-loop control (23) adjusts the generator output power to said maximum transferrable drive torque.

Abstract: During laser beam welding a so-called end crater forms at the end of the weld seam. The end crater is formed by the volume shrinkage of the solidifying melt after the laser beam reaches the seam end and is switched off or repositioned. The end crater acts as a geometric notch and decreases the mechanical characteristics, in particular the operational stability, of the weld seam so that holes or tears in the area of the end crater can occur. The task of the present invention is thus comprised of providing a process for reducing end crater formation. The task is solved in that towards the seam end the focus of the laser beam is distanced from the surface to be welded and/or a transverse movement of the beam occurs.

Abstract: With many coated plates, in particular zinc (galvanized) and organic coated sheet metal as are employed in the automobile industry, the coating material has a significantly lower boiling point than the melting point of the sheet metal material. Therefore in the case of laser welding of this type of sheet metal with zero gap in the overlap abutment area to a explosion like vaporization of coating material, which take along or entrain molten sheet metal material and strongly damage the quality of the joint. For improving the connection it has already been proposed that no gap be provided between the sheets, but rather these are positioned directly over each other and then first by means of first laser beam to warm until vaporization of the coating and subsequently to weld the uncoated sheets by means of a second laser beam. The disadvantage therein is above all the elaborate apparatus set up or complexity for the two required optical systems.

Abstract: When laser beam welding two or more work pieces, the weld seam is usually visible on the work piece that is farthest from the laser beam, on the side of this work piece away from the laser beam. If this side is in an exposed area, then it must be reworked, which is expensive. The task of the present invention therefore consists of providing a method and a device for laser beam welding, with which a laser-welded seam can be formed without being so noticeable. The task is solved by determining the critical energy input per area unit and time unit into the work piece to be welded, above which an appearance of the welded seam to a degree exceeding a predetermined level will occur on the side away from the laser beam of the work piece that is farthest removed from the laser beam, and that the laser beam is controlled or regulated in such a way that the critical energy input per area unit and time unit is not exceeded.

Abstract: When laser beam welding one or more work pieces faults may occur, which lead to unacceptable losses in quality. For quality assurance, both subjective visual inspections as well as automated checks of the seam are the norm. In the automated processes the work site is conventionally monitored during welding using point or surface detectors (cameras). This type of process can not detect faults which do not occur until after the actual interaction of laser beam and work piece, in particular, solidification phenomena. Beyond this, certain irregularities relevant to quality are not recognized, since relevant process signals are overridden by stronger signals of the process illumination with no information value. It is the task of the present invention to provide a check process, which reliably recognizes seam faults.

Abstract: The use of ?-zeacarotene, ?-zeacarotene or a mixture of both as a coloring agent for food or pharmaceutical compositions. For addition to the food or pharmaceutical composition or otherwise incorporation therein during its preparation the zeacarotene (mixture) is generally first formulated to a solid or liquid colorant composition in the form of a stable water-soluble or -dispersible powder, an aqueous colloidal solution or oil-in-water dispersion of such powder, an oil-in-water dispersion of the zeacarotene (mixture), or an oil-soluble dispersion of the zeacarotene (mixture) in a triglyceride. In a solid colorant composition the zeacarotene (mixture) is generally finely dispersed in a matrix or carrier.

Abstract: During welding of higher stiffness steels there is significant tendency towards hardening in the area of the weld seam, which introduces a loss in ductility and thus strongly reduces the durability and quality of the construction components.
