Abstract: A method for controlling a starting process of a vehicle includes activating a control sequence and setting a control sequence signal, defining a maximum engine drive torque, and detecting a drive request for a starting process. The method further includes, in response to the drive request, controlling a clutch-gearbox unit with an engagement process duration, controlling wheel slip of driven wheels by determining wheel speeds of the driven wheels and at least setting an output drive torque at the output shaft, and redefining the maximum engine drive torque depending on the wheel slip and a driving speed. The method also includes deactivating the control sequence and resetting the control sequence signal when limit values are reached.

Abstract: A method for producing a metal strip coated with a coating that contains chromium metal and chromium oxide and is electrolytically deposited from an electrolyte solution that contains a trivalent chromium compound onto the metal strip by bringing the metal strip, which is connected as the cathode, into contact with the electrolyte solution. An efficient deposition of coating with a high proportion of chromium oxide is obtained by successively passing the metal strip through a plurality of electrolysis tanks. The electrolyte solution in at least the last electrolysis tank, as viewed in the strip travel direction, or in a rear group of electrolysis tanks has an average temperature of at most 40° C., and the electrolysis time, during which the metal strip is in electrolytically effective contact with the electrolyte solution in the last electrolysis tank or in the rear group of electrolysis tanks is less than 2.0 seconds.

Abstract: A valve (1) has a housing base (2) and a valve seat (18) supported by the housing base (2). An annular slide (12) is displaceable linearly relative to the housing base (2) between first and second operating positions. A sealing edge (17) of the annular slide (12) bears in a sealing manner against the valve seat (18) when the annular slide (12) is in the first operating position. However, the annular slide (12) is raised from the valve seat (18) in the second operating position to enable flow through the annular slide (12). At least one flow deflecting element (27) is provided to deflect a fluid flowing between the sealing edge (17) and the valve seat (18).
