20140152483 | METHOD AND DEVICE FOR TESTING THE MATERIAL OF A TEST OBJECT IN A NONDESTRUCTIVE MANNER - A method for testing the material of a test object ( | 06-05-2014 |
20110259108 | ELECTROMAGNETIC-ACOUSTIC TRANSDUCER AND ULTRASONIC TEST SYSTEM HAVING THE SAME - An electromagnetic-acoustic transducer for ultrasonic testing of test objects which are composed substantially of an electrically conductive material includes a magnet system that produces a magnetic field intended to penetrate into the test object, and an inductive coil arrangement that produces an electromagnetic alternating field superimposed on this magnetic field in the test object, and that detects electromagnetic alternating fields emitted from the test object, wherein magnet system is arranged in a magnetization unit, the coil arrangement is arranged in a probe unit separate from the magnetization unit, the probe unit is mounted such that it can move relative to the magnetization unit in the area of the magnetic field. | 10-27-2011 |
20110234213 | TEST METHOD AND TEST APPARATUS FOR TESTING ELONGATED OBJECTS USING COIL - A test method for testing elongated objects comprising moving an elongated object in a feed-through direction through a feed-through coil arrangement having at least one feed-through coil, wherein the feed-through coil arrangement is secured to be transversely movable with respect to the feed-through direction of the object and is guided on the object passing through such that the feed-through coil arrangement can follow transverse movements of the object occurring transversely with respect to the feed-through direction of the object. | 09-29-2011 |
20110037461 | METHOD AND DEVICE FOR DETECTING NEAR-SURFACE DEFECTS BY MEANS OF MAGNETIC LEAKAGE FLUX MEASUREMENT - In a method for detecting near-surface defects in a test sample consisting at least partly of a ferromagnetic material, a test volume of the test sample is magnetized and scanned for the detection of magnetic leakage fields caused by defects. The test volume is magnetized by means of a magnetic constant field and simultaneously by means of a magnetic alternating field superposed on the constant field. Leakage field test devices suitable for carrying out the method are described. | 02-17-2011 |
