摘要： A method for detecting flaws in a railhead, which railhead (1) is provided with a top side (T), a bottom side (B) and longitudinal sides (S) extending between that top side (T) and bottom side (B), wherein at least one ultrasonic first signal (10) is transmitted into the railhead (1) via said head top side (T) and traverses such a transmission path (9) that: - the signal (10) is only once reflected by the railhead bottom side (B), and not by a railhead longitudinal side (S); - the signal (10) reaches at least one substantially central railhead part (C); and - the signal (10) can exit the railhead (1) via the head top side (T); wherein first ultrasonic signals exiting the head top side (T) are detected, wherein the transmission path (9) of the at least first signal (10) extends in a virtual transmission plane, which transmission plane extends substantially transverse to a longitudinal direction (L) of the rail. In addition, the invention provides an apparatus for detecting flaws in a railhead. The invention further relates to a positioning method.

摘要： A method for ultrasonic testing of an object, wherein at least one test moment an ultrasonic test signal (S1, S2) is transmitted into the object (2), while after a particular verification period (Δt 1 , Δt 2 ) measured from said test moment, an ultrasonic verification signal (S1’, S2’) is transmitted into the object (2), a possible echo of said test signal (S1, S2) being received from said object (2) at a particular first measuring moment, the possible echo being accepted as being the echo (E1, E2) of said test signal (S1, S2) only when the echo (E1’, E2’) of the verification signal is received at a particular second measuring moment. In addition, the invention provides an apparatus, evidently intended and designed for carrying out such a method and a use of such an apparatus.

摘要： A device (100) is described for generating a measuring signal (M) being indicative for surface properties of an object (3) which is substantially manufactured of a ferromagnetic material (1). The device comprises: at least one magnet (20) with a magnet axis (21); two magnetic field sensors (30; 40) arranged at mutually different axial positions with respect to the said magnet axis (21); a control member (10) provided with inputs (12; 14) coupled with the magnetic field sensors (30; 40) for receiving the sensor signals (S1; S2) generated by these magnetic field sensors (30; 40), and provided with an output (19) for issuing the measuring signal (M). The control member (10) is adapted for generating the measuring signal (M) based on the sensor signals (Sl; S2) received from both magnetic field sensors (30; 40), according to the formula M = αSl - αβS2, wherein α and β are multiplication factors.
