Abstract: The invention relates to the use of a composition comprising a vitamin, a metal ion, and a surfactant, as a therapeutic agent or disinfectant. The composition has been known as a decontaminant because the same efficiently decomposes DNA. It has now been possible to demonstrate that the agent has surprisingly good compatibility while having a wide-ranging disinfecting effect and is therefore also suitable for other purposes, e.g., for disinfecting or dressing wounds.

Abstract: An actuating device for actuators, such as switching, throttle or swirl flaps, in internal combustion engines for motor vehicles comprises a shaft connected with an actuating motor. The shaft is connected with an actuator, such as a switching flap or the like. In a predetermined position relative to the shaft two pin-type magnets are arranged and preferably connected with a partly toothed gearwheel. When the shaft is rotated, the pin-type magnets move relative to a preferably fixed magnetic field sensor. The magnetic field sensor is a linear Hall sensor. Provision of a linear Hall sensor allows three different shaft positions to be determined. The positions are the two shaft positions defined by the pin-type magnets in which the magnets are arranged opposite the Hall sensor, and a position in which the location of the pin-type magnets does not allow the Hall sensor to detect a magnetic field. In the latter position the linear Hall sensor has a defined bridge voltage.

Abstract: In a method for controlling a switching flap (10) arranged in an intake pipe connected with an internal-combustion engine the switching flap (10) is rotated with the aid of a switching-flap shaft (12) connected with an electromotor (18). With the aid of a position-detecting device (22,26;24,26) an end position of the switching flap (10) is detected. Subsequently, a rotation force is continued to be applied to the shaft (12) to hold the switching flap (10) in the end position. For detecting a breakage of the switching-flap shaft (12), an error message is generated when the switching-flap shaft (12) continues to rotate beyond the end position.
