Abstract: The invention relates to a transmission coil (10) configured for inductive energy transfer, comprising a carrier (17), a coil arrangement (11) having a plurality of turns (12), and a capacitance. It is thereby provided that the capacitance is formed of a plurality of capacitors (22), wherein each capacitor (22) is assigned to an individual turn (12) or to a group of at least two turns (12) of the coil arrangement (11), and together with the coil arrangement, the capacitors (22) are arranged on the carrier (17). The invention further relates to a stationary charging station and to a vehicle, each comprising such a transmission coil (10), and to a system for the inductive charging of vehicles.

Abstract: A method for identifying electrical faults in a generator assemblage, in particular of a motor vehicle, which assemblage includes a generator having a generator regulator and a rectifier having rectifier elements, the method encompassing ascertaining, in the context of at least one excitation current value of an excitation current through an excitation winding of the generator, at least one respective parameter that corresponds to a current conduction time proportion of at least one of the rectifier elements, and determining that an electrical fault exists if the at least one parameter deviates by more than a predetermined amount from an associated expected value. Also described is an apparatus for implementing the method.
Abstract: The invention relates to a measuring device, especially for a machine tool and/or a manual measuring device, comprising a measuring unit (12a-d) that is adapted to measure and an external signal recognition unit (14a-d). The invention is characterized in that the external signal recognition unit (14a-d) is adapted to recognize an external signal during and/or prior to a measurement of the measuring unit (12a-d).

Abstract: A tubular valve housing includes a guide body for pressure fluid that is disposed between a valve body having a hollow-conical valve seat and a chamber of the valve housing, in which actuating means of the valve are received in the chamber. The guide body is penetrated by a closing body of the valve which divides the chamber from an annular conduit. The annular conduit carries the pressure fluid and communicates with the valve seat and has circumferential outlet openings of the valve housing. The guide body is braced on the valve body, with a face end contacting the valve body, and has guide conduits, fitting over an outline of the valve seat, which on the outlet side discharge into the annular conduit. The face end of the closing body, which cooperates with the valve seat, is a spherical portion that makes a transition with sharp edges to the cylindrical shaft of the closing body.
