Abstract: A method and device for nondestructive and noncontact detection of faults in a test piece, or electrically conductive particles in a liquid flow, moving passed the device, using eddy currents. The test piece or flow is exposed to periodic alternating electromagnetic fields. A periodic electrical signal is detected. The receiver coil signal is digitized with an A/D converter stage. A useful signal is produced from the digitized receiver coil signal with a signal processing unit, and the useful signal is evaluated with an evaluation unit for detecting a fault in the test piece or electrically conductive particles. When overdriving of the A/D converter stage by the receiver coil signal is ascertained by monitoring the curve shape of the digitized receiver coil signal, a part of the receiver coil signal truncated by the A/D converter stage is reconstructed using a mathematical approximation in the digitized receiver coil signal.

Abstract: The invention relates to methods for producing annular moldings subjected to tensile or pressure loading from plastic by using an injection mold having a main cavity, at least one extra cavity is incorporated in the injection mold. The at least one extra cavity is joined to the main cavity by a connecting duct. The main cavity is filled with plastic melt so a flow line is formed in the vicinity of the connecting duct between the at least one extra cavity and the main cavity, wherein the cross section of the connecting duct is dimensioned such that, during the filling of the main cavity, no plastic melt flows into the extra cavity. The filling pressure is increased until plastic melt flows into the extra cavity; flow taking place through the flow line produced during the filling of the main cavity. Subsequently, the injection mold is opened and the molding removed.

Abstract: An ergonomically equipped and interference signal-reducing position measurement probe for mutual alignment of bodies has a speech input device and/or a speech output device. The probe is wirelessly linked to an external control or a higher-level supervisory computer either by an infrared interface or a radio link which operates at an extremely high frequency. Error-reducing measured value acquisition is effected by averaging. The average represents several individual measured value. In the acquisition of the individual measured values, it is watched that the times of measured value recording and the time peaks of a solid-borne sound oscillation on the measurement object are essentially asynchronous to one another.
