Apparatus for generating, directing and receiving ultrasonic wave trains

Claim 2

IN AN ULTRASONIC WAVE DIRECTOR FOR USE IN THE NONDESTRUCTIVE TESTING OF OBJECTS UTILIZING AN ULTRASONIC GENERATOR, A BODY FORMED OF MATERIAL CAPABLE OF CARRYING ULTRASONIC WAVE TRAINS, SAID BODY HAVING AN INPUT SURFACE FOR ULTRASONIC COMMUNICATION WITH AN ULTRASONIC WAVE GENERATOR AND HAVING AN OUTPUT SURFACE ADAPTED TO BE PLACED IN COMMUNICATION WITH THE TEST OBJECT FOR TRANSMITTING AND RECEIVING ULTRASONIC WAVE TRAINS THEREFROM, THE REGION OF SAID BODY BETWEEN THE INPUT AND OUTPUT SURFACES DEFINING ULTRASOUND PATHS THROUGH SAID BODY, THE PORTIONS OF SAID BODY ADJACENT AT LEAST ONE SIDE OF SAID PATHS BEING PROVIDED WITH A PLURALITY OF SPACED SLOTS, SAID SLOTS MAKING A SUBSTANTIAL ANGLE TO SAID PATHS, SAID OUTPUT SURFACE HAVING A SURFACE AREA GENERALLY COMMENSURATE WITH THE AREA OF CONTACT BETWEEN THE ULTRASONIC GENERATOR AND THE INPUT SURFACE, SAID INPUT SURFACE, SAID OUTPUT SURFACE AND SAID PATH BEING IN GENERAL ALIGNMENT AND COOPERATING TO DIRECT ULTRASONIC WAVE TRAINS FROM SAID INPUT SURFACE THROUGH THE BODY AND TO AND FROM SAID OUTPUT SURFACE, SAID BODY FURTHER INCLUDING A PORTION ADJACENT SAID PATHS FOR ATTENUATING AND DELAYING RECEIVED ULTRASONIC WAVE TRAINS WHICH TRAVEL IN DIRECTIONS OTHER THAN ALONG SAID PATHS.

Claim 3

IN AN ULTRASONIC WAVE DIRECTOR ASSEMBLY FOR NONDESTRUCTIVE TESTING OF OBJECTS USING AN ULTRASONIC TRANSDUCER, A BODY FORMED OF MATERIAL CAPABLE OF CARRYING ULTRASONIC WAVE TRAINS, SAID BODY HAVING AN OUTPUT SURFACE ADAPTED TO BE PLACED IN ULTRASONIC COMMUNICATION WITH THE TEST OBJECTION FOR TRANSMITTING AND RECEIVING ULTRASONIC WAVES THEREFROM, THE BODY HAVING A CURVED INPUT SURFACE, SAID INPUT SURFACE HAVING A RADIUS OF CURVATURE INTERSECTING THE OUTPUT SURFACE, THE REGION OF SAID BODY BETWEEN THE INPUT AND OUTPUT SURFACES DEFINING ULTRASOUND PATHS THROUGH SAID BODY, SAID BODY FURTHER INCLUDING A PORTION ADJACENT SAID PATHS FOR ATTENUATING AND DELAYING RECEIVED ULTRASONIC WAVE TRAINS WHICH TRAVEL IN DIRECTIONS OTHER THAN ALONG SAID PATHS, AND A MOVABLE TRANSDUCER HOLDER MOUNTED ON SAID BODY, SAID MOVABLE TRANSDUCER HOLDER INCLUDING A SURFACE IN INTIMATE CONTACT WITH THE INPUT SURFACE OF SAID BODY AND INCLUDING A SECOND SURFACE FOR RECEIVING ULTRASONIC WAVE TRAINS FROM A TRANSDUCER, SAID SECOND SURFACE BEING SPACED APART FROM SAID SURFACE IN INTIMATE CONTACT WITH THE TRANSMIT INPUT SURFACE OF THE BODY, MEANS FOR PIVOTALLY MOUNTING SAID MOVABLE TRANSDUCER HOLDER SO THAT THE HOLDER IS CAPABLE OF BEING MOVED ALONG THE INPUT SURFACE WHILE MAINTAINING INTIMATE CONTACT THEREWITH, POWER MEANS CARRIED BY THE BODY, AND MEANS CONNECTED TO SAID TRANSDUCER HOLDER AT POINTS LYING ON A LINE PASSING THROUGH THE AREA OF CONTACT BETWEEN THE TRANSDUCER HOLDER AND THE INPUT SURFACE OF THE BODY FOR TRANSMITTING FORCES SUPPLIED BY SAID POWER MEANS TO SAID TRANSDUCER HOLDER FOR MOVING THE SAME.

Claim 4

IN AN ULTRASONIC WAVE DIRECTOR ASSEMBLY FOR NONDESTRUCTIVE TESTING OF OBJECTS USING AN ULTRASONIC TRANSDUCER, A BODY FORMED OF MATERIAL CAPABLE OF CARRYING ULTRASONIC WAVE TRAINS, SAID BODY HAVING AN OUTPUT SURFACE ADAPTED TO BE PLACED IN ULTRASONIC COMMUNICATION WITH THE TEST OBJECTION FOR TRANSMITTING AND RECEIVING ULTRASONIC WAVES THEREFROM, THE BODY HAVING A CURVED INPUT SURFACE, SAID INPUT SURFACE HAVING A RADIUS OF CURVATURE INTERSECTING THE OUTPUT SURFACE, THE REGION OF SAID BODY BETWEEN THE INPUT AND OUTPUT SURFACES DEFINING ULTRASOUND PATHS THROUGH SAID BODY, SAID BODY FURTHER INCLUDING A PORTION ADJACENT SAID PATHS FOR ATTENUATING AND DELAYING RECEIVED ULTRASONIC WAVE TRAINS WHICH TRAVEL IN DIRECTIONS OTHER THAN ALONG SAID PATHS, AND A MOVABLE TRANSDUCER HOLDER MOUNTED ON SAID BODY, SAID MOVABLE TRANSDUCER HOLDER INCLUDING A SURFACE IN INTIMATE CONTACT WITH THE INPUT SURFACE OF SAID BODY AND INCLUDING A SECOND SURFACE FOR RECEIVING ULTRASONIC WAVE TRAINS FROM A TRANSDUCER, SAID SECOND SURFACE BEING SPACED APART FROM SAID SURFACE IN INTIMATE CONTACT WITH THE TRANSMIT INPUT SURFACE OF THE BODY, MEANS FOR PIVOTALLY MOUNTING SAID MOVABLE TRANSDUCER HOLDER SO THAT THE HOLDER IS CAPABLE OF BEING MOVED ALONG THE INPUT SURFACE WHILE MAINTAINING INTIMATE CONTACT THEREWITH, POWER MEANS CARRIED BY THE BODY, AND MEANS CONNECTED TO SAID TRANSDUCER HOLDER AT POINTS LYING ON A LINE PASSING THROUGH THE AREA OF CONTACT BETWEEN THE TRANSDUCER HOLDER AND THE INPUT SURFACE OF THE BODY FOR TRANSMITTING FORCES SUPPLIED BY SAID POWER MEANS TO SAID TRANSDUCER HOLDER FOR MOVING THE SAME.
