In one example, the vehicle tyre is supplied (100) to a marking station (10), the vehicle tyre (20) is aligned and centred (102, 103) in the marking station (10), marking is performed (108) in the marking station in accordance with characteristics of the vehicle tyre (20), and marking is performed (108) using one marking device (12) from a multiplicity of different marking devices (12). The method according to the invention is distinguished by the fact that the marking device (12) for marking the vehicle tyre (20) is positioned (107) at the vehicle tyre (20) by means of a robot arm (11).

Abstract: A connection device for connecting a ventilating line to an intake air flow guide of an internal combustion engine, wherein the connection device has a non-return valve for preventing a flow from the intake air flow guide into the ventilating line. The connection device has at least one hole which is arranged upstream of the non-return valve and connects an interior chamber of the connection device to a surrounding area of the connection device.

Abstract: A vibration damper for a vehicle, includes at least one cylinder tube forming a fluid chamber, in which a piston assembly is axially and slidingly arranged and divides the cylinder tube into two working chambers, an upper and a lower working chamber, and wherein the piston assembly has an axially moveable main piston which is axially fixed to a piston rod that can move axially relative to the cylinder tube, and which has a piston valve influencing the fluid flow between the upper and lower working chambers, and wherein a further stroke-dependent piston is arranged on an axial extension of the piston rod in the direction of the cylinder base, which operates once a determined damper stroke is achieved. The stroke-dependent piston has a smaller diameter than the main piston and only operates when plunging into a smaller diameter of an inner casing surface.

Abstract: The invention relates to faceted gemstones based on a luminescent glass composition that contains particular oxides of rare earth metals and thus enables the faceted gemstones to be identified, and to a process for identifying the gemstones.

Abstract: A motor vehicle has an air intake system with an air duct. The air duct has an air inlet for taking in ambient air and an air outlet. The air duct has a curved bent section which, upstream, is closer to a vehicle running surface than downstream. In the event of a water level of water entering the air duct that is rising parallel to the vehicle running surface, the internal cross section of the bent section is closed by the water before the water can pass the bent section. A plurality of air openings downstream of the bent section is introduced through a wall of the duct in an outer surface of the duct that points away from the vehicle running surface.

Abstract: The trampoline (1) as per the invention is comprised of a frame structure (2) and a jumping mat mounted in the frame structure (2). An arrangement of sensors (8) is provided by means of which forces or accelerations acting on the jumping mat (3) are recorded. The signals of the sensors (8) are read into an evaluation unit (9). Output quantities are generated from the chronological progression of the signals.
