    摘要: According to a method, initial temperatures (T1) of strip points (101) are detected when the hot-rolled strip (6) is fed to the production line. The strip points (101) are monitored on their way through the production line. The hot-rolled strip (6) is subjected to temperature influences (delta T) in the production line (3). The strip points (101), the initial temperatures (T1), the monitored values (W(t)) and the temperature influences (delta T) are supplied to a model (9) for the production line (3). The model (9) determines expected actual temperatures (T2) of the strip points (101) in real time and allocates them to the strip points as the new actual temperatures (T2).

    摘要: In a computer aided design system, a geometric object is defined as a function, preferably a B-Spline, of a piecewise polynomial function. In order to make a local modification of said geometric object, a point of origin (P) is picked. A second point (P') is defined as a target point through which the modified function should pass. The move from the point of origin (P) to the target point (P') is transformed into a move, preferably a parallel shift, of the control points of the associated control polygons.

    摘要: A method is disclosed for operating a mill at continuous input and output mass flows, and to the mill, wherein a process model based on power balance equations and mass balance equations is used. Characteristic process variables can be measured in a simple manner outside the mill. Characteristic process variables which are still not known can be ascertained by means of inserting the measured values into a respective power balance equation, assuming that the other process variables are in each case known or are insignificant. On this basis, the mill can be actuated in an optimum manner in order to provide a high output power.

    摘要: An adsorption unit for combustion gas of an internal combustion engine has an adsorption housing having a chamber section with an inner wall. An adsorption element disposed in the adsorption housing is made of a gas-permeable adsorption medium that is formed to a hollow body and encloses an interior of the adsorption element. The hollow body has opposed open ends. A main flow passage extends through the hollow body and the combustion gas flows in main flow direction through the hollow body. The adsorption element has an exterior circumferential side facing away from the interior and delimiting together with the inner wall of the chamber section a bypass chamber surrounding the absorption element outwardly. In the main flow direction, the bypass chamber has a downstream end that is closed off and an upstream end that has at least one bypass opening that communicates with the main flow passage.
