Abstract: A method analyzes risks in a technical project for developing or manufacturing a technical system or technical components or a technical process, wherein the following steps are carried out in a risk identification process: a) provision or determination of a large number of qualitative evaluations of risks in the technical project; b) determination of a large number of quantitative evaluations of the risks; c) comparison of the qualitative and quantitative evaluations for each risk, as a result of which a comparison outcome is established for each risk; d) definition of a permissible region of comparison outcomes; e) classification of the risks that are situated outside the permissible region as unacceptable risks; f) analysis of the unacceptable risks in order to identify uncertainties in the risk analysis and further risks.

Abstract: A method and apparatus for determining wear and tear in machines includes a method that determines a voltage draw and/or a current draw of a first subsystem of the machine during its operation, and wear and tear present in a second machine subsystem is determined based on the draw determined in the first subsystem. In one embodiment, a coal grinding machine includes a drive, a coal grinding mill driven by the drive, a device for determining an electrical draw of a current and/or voltage draw of the drive during operation, and a device for inferring wear and tear present in the coal grinding mill on the basis of voltage and/or current draw determined in the drive. The machine can include a device for inferring the quality or type of material (like coal) being processed in the mill based on the draw determined in the drive.

Abstract: To so improve a machine tool comprising a machine frame, a rotary table mounted on the machine frame for rotation about a center axis, machining stations arranged around the rotary table, at least one holding device mounted on the rotary table for rotation about an axis of rotation, and a rotary drive, that during rotation of the rotary table from machining station to machining station, rotation of the holding device through optionally small or optionally large angles is possible, it is proposed that the rotary drive comprise a first and a second cam track held stationarily on the machine frame and a first and a second cam element mounted on the rotary table so as to move along the cam track as the rotary table rotates, that the first cam track be located in a first surface and the second cam track in a second surface, and that the first and second cam elements be coupled for rotating the holding device and in each of their positions along the cam tracks hold the holding device in a clearly defined rotary pos
