1. An inspection system, comprising the combination of:

  • (a) a receptacle having interconnected walls defining a cavity for holding energy coupling liquid and receiving an object to be inspected in the liquid, at least one wall having interior and exterior surfaces, a longitudinal bore defined between and spaced from said surfaces and extending within said one wall from one end of said longitudinal bore to an opening at an opposite end of said longitudinal bore located at a top of said one wall above said cavity, and a transverse bore intersecting with said one end of said longitudinal bore and open at both said interior and exterior surfaces of said one wall;

    (b) a transducer having first and second opposite ends, said transducer being operable for sending waves of energy from said first end into said cavity toward the object and receiving echoes of energy at said first end from the object for measuring a parameter of the object, said transducer having means at said second end for transmitting input and output signals to and from said transducer;

    (c) means removably disposed in said longitudinal and transverse bores of said one wall for removably mounting said transducer in said transverse bore of said one wall such that said first end of said transducer communicates with said cavity and said second end of said transducer communicates with the exterior of said receptacle; and

    (d) a transverse cylindrical recess defined in said one wall and intersecting with said transverse bore at said one end of said longitudinal bore intersected by said transverse bore;

    (e) said mounting means including a cylindrical bearing mounted in said cylindrical recess and extending across said transverse bore and said one end of said longitudinal bore, said bearing having a central opening for receiving and holding said transducer, said mounting means also including a member mounted in said longitudinal bore and adjustably engageable with said bearing for holding said bearing and thereby said transducer in a stationary position.
