  • Patent number: 4602212
    Abstract: A technique for detecting flaws in a metal product which uses a combined eddy current and magnetic flaw detection technique. A first magnetic field having flux lines parallel to the surface of the test object and a second field having flux lines perpendicular to the surface of the test object are generated. The resultant magnetic field is affected by faults in the metal test object. A magnetic field detector adjacent the test object detects the resultant magnetic field and produces an output signal which is processed by a circuit to provide a pair of component signals representing the portion of the output signal corresponding to the individual components of the resultant magnetic field, thus providing an indication of the type of faults that are present in the test object.

  • Patent number: 4247818
    Abstract: The present invention is an automatic sensitivity adjustment apparatus for calibration of a nondestructive inspection instrument with a reference standard. Calibration is performed by setting the gain of a variable gain amplifier while a reference standard containing a standard flaw is passed before the sensing means of the instrument. A discriminator circuit connected to the sensing means detects when the output of the sensing means exceeds a predeterminedlevel. A hold time controller sends a sampling enable signal to a peak hold circuit which is also connected to the sensing means to cause the peak hold circuit to sample the sensing means output. The hold time controller senses the peak in the response of the sensing means and causes the peak hold circuit to hold that peak value. The output of the peak hold circuit is applied to the input of a variable gain amplifier. A comparator compares the output of the variable gain amplifier with a reference voltage produced by a reference voltage setting means.

  • Patent number: 4127813
    Abstract: A method is provided for balancing the sensitivity of two channels comprising intermittently-appearing pulse waves, such as the signals generated by respective sensors in a detecting couple which is used in the so-called differential detection of flaws in materials. The balancing of the levels of the pulse signals is accomplished by the use of, essentially, a pair of sample and hold circuits, one or two variable gain amplifiers and the same number of comparison loops as variable gain amplifiers.
