Abstract: A process for stabilizing strip in a plant for coating strip material, in which a metal strip is taken through a container holding molten coating material that has, below the melt surface, a through channel, in which induction currents are induced by an electromagnetic travelling field in the coating material and, in interaction with the electromagnetic travelling field, generate an electromagnetic force to retain the coating material. In the region of the through channel, a controllable magnetic field superimposed on the modulation of the electromagnetic travelling field is applied, whose field strength and/or frequency are adjustable as a function of sensor-detected position of the strip in the coating channel.

Abstract: The invention involves a suspended trolley line, particularly an electric monorail line with at least one undercarriage movable along running rails and with a running wheel that may be driven along the rail. At least two frictional wheels are spaced from each other and positioned on the running wheel. The frictional wheels are guided on the undercarriage by a connecting element and are braced against each other by a spring element, such that the frictional wheels additionally contact the supplemental rail and impinge upon the running wheel with pressure when in an operating position. The supplemental rail is located at least partially parallel to the running rail and spaced therefrom. The driven undercarriage is simple in its construction and has improved traction characteristics and therefore is particularly capable of being used in ascending and descending sections of the trolley line. The frictional wheels, the connecting element and the spring element form an assembly unit lying on the running wheel.

Abstract: A process for automated vehicle-autonomous detection of a particular traffic situation by continuously detecting an instantaneous vehicle speed onboard a vehicle. The detected vehicle speeds are classified using guidelines which may be based on rigid values or on fuzzy logic relationships, into one or more of a plurality of traffic categories by assigning a weight for that detected vehicle speed to each of the traffic categories. Thereafter, for each traffic category the weights associated with the detected speed values are integrated over time to calculate an integrated result for each traffic category. The integrated results of the traffic categories are then evaluated based on predetermined rules or criteria to generate a probabilistically-based traffic detection value indicating the traffic category representing the vehicles' current traffic situation. The traffic categories and guidelines or membership functions or relationships are defined for use with a particular type of road.
