Abstract: A method for determining the Ethanol content of the fuel in a motor vehicle uses the dependence of the lean-running limit of the internal combustion engine on the ethanol content of the fuel to determine the ethanol content, by the fact that the ethanol content is arrived at from the required reduction in the injected fuel quantity to reach the lean-running limit.

Abstract: In a method for checking temperature values of a temperature sensor of an internal combustion engine, a first temperature value is recorded during a first predefined time period close in time to an operating state of the starting of the internal combustion engine. With the method a check is made to determine whether a cold start of the internal combustion engine is present. An error in the first temperature value is detected if the cold start is detected and the first temperature value is greater than a temperature threshold value.

Abstract: The present invention relates to an epilating apparatus (10) comprising means (12) for extracting hairs from skin and means (16, 20) for reducing pain. In accordance with the present invention the means (16, 20) for reducing pain apply at least two of the following stimuli: heat, cold, vibration.

Abstract: The present invention relates to a cooling device (10) for a personal care system (10, 12), said cooling device (10) comprising a cooling device housing (14) and heatconducting means (6, 18) for transferring cold from the interior of said cooling device housing (14) to skin (20) to be cooled, said heat-conducting means (16, 18) comprising a contact piece (18) for contacting said skin (20). Furthermore, the invention relates to a personal care system (10, 12), especially to a personal care system (10, 12) comprising a depilation device (12). To ensure a proper contact between the active surface (32) of the depilation device (12) and the skin (20) as well as between the contact piece (18) and the skin (20) even in cases where the appliance angle a is not optimal, in accordance with the invention at least a part of said contact piece (18) is movable with respect to said cooling device housing (14).

Abstract: The present invention provides a process for preparing 2-amino-4-chloro-6-alkoxypyrimidines by reacting the 2-amino-4,6-dichloropyrimidine with an alkali metal alkoxide or a mixture of alkali metal hydroxides and an alcohol, in which the reaction is effected in a polar aprotic solvent (or solvent mixture), the solvent is subsequently distilled off to an extent of >30% and the product is precipitated by adding water during or after the distillation. This process, in which the polar aprotic solvent used may in particular be acetone and which can be performed at temperatures between 5 and 60° C., allows 2-amino-4-chloro-6-alkoxypyrimidines and in particular 2-amino-4-chloro-6-methoxypyrimidine to be prepared in high yields and at simultaneously very marked purity in a particularly economically viable and environmentally benign manner.

Abstract: An internal combustion engine has an intake duct, at least one cylinder that takes in air via the intake duct and an exhaust gas duct, in which the exhaust gas catalytic converter is located, and into which the combusted air/fuel mixture is ejected from at least one cylinder. Depending on measurement values that are determined by sensors, input signals for the control of actuators of the internal combustion engine are generated by means of control functions based on torsional moment and by means of a dynamic charging model of the intake duct. A measurement is determined, which characterizes the difference of a desired air mass flow into the respective cylinder from an actual air mass flow into the cylinder. Depending on the measurement, a proper or improper heating up of the exhaust gas catalytic converter is identified.

Abstract: For shaping longitudinal grooves or comparable longitudinal structures into round housings or housings which are otherwise regularly shaped with respect to a longitudinal axis, a press is provided with a deforming tool whose top tool presses a workpiece through a corresponding roll arrangement of a bottom tool. The bottom tool has an opening which is coaxial to the top tool contains an axially displaceable cage provided with a group of rolls. The rolls are rotatably disposed in the cage and are supported on radially exterior abutments which are stationarily held in the bottom tool. The rolls are constructed as profile rolls and shape the desired longitudinal structures into the workpiece when it is moved through between the profile rolls. The resulting radial reaction forces are absorbed exclusively by the abutments and not by the cage. For supporting the longitudinal movement of the cage, a transmission is formed, for example, by gear wheels which are rotatably disposed on the cage.
