Claim 1
Independent Claim
127 words
A FLAW DETECTION SYSTEM USING PULSED ULTRASONIC WAVES COMPRISING WAVE GENERATING AND RECEIVING MEANS HAVING A CURVED SURFACE CONSTRUCTED TO GENERATE AND TRANSMIT INTO A MEDIUM TO BE EXPLORED A DIVERGENT BEAM OF PULSED ULTRASONIC WAVES AND TO RECEIVE WAVES REFLECTED BY FLAWS, SAID MEANS COMPRISING A TRANSDUCER SO SHAPED AS TO PRODUCE A BEAM SUBSTANTIALLY DIVERGENT IN ONE PLANE ONLY, MEANS FOR PRODUCTING RELATIVE MOVEMENT BETWEEN SAID DIVERGENT BEAM AND THE MEDIUM IN THE PLANE IN WHICH THE BEAM IS DIVERGENT AND TRANSVERSE TO THE BEAM, AND A DISPLAY DEVICE CONNECTED TO PROVIDE A GRAPHICAL REPRESENTATION OF THE TWO COORDINATES WHICH REPRESENT RESPECTIVELY THE SAID RELATIVE MOVEMENT BETWEEN THE BEAM AND THE MEDIUM AND THE RANGE OF THE FLAW FROM THE WAVE GENERATING AND RECEIVING MEANS.
