  • Testing method using ultrasonic energy
    Patent number: 4080839
    Abstract: A convergent ultrasonic beam is formed by an emitter made as a sphere and directed to a piece under test. Having been reflected from the surface of the piece and from the defect, the ultrasonic beams are separated in space. The ultrasonic beam carrying information on the defect is displayed.

  • Method of ultrasonic echo flaw detection and device for effecting same
    Patent number: 3978714
    Abstract: In the course of checking an article, there are directed at the point on the article being checked, whereat ultrasonic oscillations generated by an ultrasonic flaw detecting transducer are applied, pulses of ultrasonic oscillations focused at this point, which pulses are sent by a side focusing ultrasonic transducer. The ultrasonic oscillations reflected from the surface of the article, in the form of a divergent beam, are received by two receiving ultrasonic transducers. The received ultrasonic oscillations are compared to obtain a difference signal; a detector head housing is then turned, depending on the magnitude and sign of said difference signal.
