Abstract: The aim of the invention is to allow a reliable quantification and classification of brake abrasion of a brake system of a vehicle and simultaneously reduce the complexity in a practical application. This is achieved by a measuring rim with a rim interior, in which a collecting housing is arranged that extends in the circumferential direction of the measuring rim over an extension angle (?). A collecting housing interior is formed in the collecting housing, and the collecting housing is at least partly open towards the collecting housing interior on a radially inner circumferential surface extending in the circumferential direction of the measuring rim. A discharge area is provided on the rim flange on the measuring rim, and a collecting channel which connects the collecting housing interior of the collecting housing to the discharge area is provided on the measuring rim.

Abstract: Various embodiments of the teachings herein include a method for designing a traffic infrastructure on the basis of height data provided by a height monitoring object comprising: a) evaluating the height data detected by a sensor unit of the height monitoring object and generating an evaluation dataset; b) identifying a component of the traffic infrastructure from the evaluation dataset; c) identifying a user of the traffic infrastructure from the evaluation dataset; and d) determining a utilization of the component by the user.

Abstract: A mesh handler for a mining machine includes a generally U-shaped frame arranged for receiving and positioning at least one mesh against a roof portion of an underground tunnel. The frame includes at least one generally U-shaped rail and a guide mechanism arranged for guiding the mesh along the rail in a direction substantially perpendicular to a longitudinal direction of the mining machine. Moreover, a mining machine including the mesh handler is provided.

Abstract: A device for the installation of rock bolts includes a supporting structure and first and second bolting units mounted to the supporting structure. Each bolting unit is configured for drilling an installation hole and/or for installing a rock bolt into a rock face, wherein the supporting structure is configured for rotatably moving the first and second bolting units about a common axis of rotation. At least one actuator is mounted to the supporting structure and configured for additionally moving at least one of the first and second bolting units.

Abstract: In a color photographic material in which at least one of the partial images yellow, magenta and cyan is produced in a double layer consisting of a first layer of lower sensitivity and a second layer of higher sensitivity and arranged further away from the layer support than said first layer, at least one color unit, preferably the blue-sensitive and/or the green sensitive color unit consists of at least three layers.(a) a first silver halide emulsion layer of low sensitivity containing a color coupler(b) a second silver halide emulsion layer which may contain a color coupler, and(c) a third layer which is free from silver halide, but contains a color coupler,the coupler in said layers a, b and c forming on color development dyes of substantially the same color which is complementary to that of the light to which the layers are sensitive.
