Abstract: An apparatus for marking a component by applying readable identifying information is provided. The identifying information has at least one identifying feature, in particular an identifying symbol. The apparatus includes a detection device which is designed to detect, on the basis of an eddy current measurement, identifying information applied or to be applied to a component by way of the apparatus.

Abstract: An embossing device for embossing a marking on a motor vehicle component includes a fastening device via which the embossing device can be fastened to a tool, by which tool the motor vehicle component can be processed. An embossing unit is held on the fastening device and has the marking in negative form, by which embossing unit the marking can be embossed into the motor vehicle component by the tool. A spring device is provided, by which the fastening device can be spring-mounted on the tool.

Abstract: A microbiological culture for triggering microbiological processes in bodies of water, soils, sediments, and/or muds contains chemo-lithoautotrophic bacteria that are immobilized. The bacteria are immobilized in a matrix having the form of capsules, gels, or gel spheres. The matrix material is selected from a wide range of natural and synthetic polymers.

Abstract: The device for securing people against a fall has a rail which is fastened by means of holders, and a runner which is guided along the rail. The rail is held movable in its longitudinal direction in the holders. The rail preferably has a closed hollow profile with roughly square cross-section and with flanges pointing away from each other on each of two opposite-facing side surfaces of the cross-section profile, the cross-section profile of the rail being symmetrical about the horizontal and the vertical axis. At least one end of the rail is preferably held in a path force limiter, which opposes a pre-set resistance to a movement of the rail.
