Abstract: A rotor system for a bicycle (1), for the purpose of bearing a fork (8) and transmitting the actuations of Bowden cables (31, 32), which each having a core (31a; 32a) includes first and second transmission elements (36, 37), that rotate relative to one another and are arranged in the area of the bearing (21, 23, 25) of the fork (8). The transmission elements include an annular region, mounted on a fork steerer (12) and surrounded by a head tube (21), and connection areas (36b; 37b) for the direct or indirect attachment of the rotor-side ends of the cores (31a 32a). At least one of the transmission elements (37) includes a connection area (37b) with a connecting element, which (32b) can be form-fittingly attached, interacting with, or being integrally connected to, the rotor side end of the core (32a) that is assigned with said at least one transmission elements (37).

Abstract: The invention relates to a process and device for measuring the effective viscosity and the elastic properties of coatings. Known measuring processes and measuring devices based on the "rolling ball method" suffer from drawbacks, namely run formation and sinking of the relatively heavy solvent vapors, due to the inclination of the coated sheet metal. To overcome these drawbacks, rolling movements are imparted to a magnetizable ball (1) displaced from its rest position in a magnetic field, during movement of the horizontally disposed substrate, under the influence of the field gradient of a permanent magnet or electromagnet (4) located below the substrate. The rolling movements are used as the basis for the measurements.
