Claims
- 1. Ultrasonic searching apparatus for use in locating a valve within a fluid conduit network, said apparatus comprising:
- a transducer mount for placement against the conduit, said transducer mount comprising a housing structure and a transducer supporting means for supporting a transducer search unit for movement within said housing structure;
- a transducer search unit held by said transducer supporting means, which search unit transmits an ultrasonic signal beam;
- beam representing member oriented parallel to the centerline of said signal beam;
- plumb means suspended from said beam representing member for defining a vertical axis;
- first protractor means for indicating the angle between said beam representing member and said vertical axis;
- flow representing member for orientation in a vertical plane which plane is parallel to the direction of fluid flow through the valve; and
- second protractor means for indicating the angle between said beam representing member and said flow representing member.
- 2. Apparatus of claim 1, wherein said flow representing member is suspended from said plumb means in a horizontal plane.
- 3. Apparatus of claim 1, wherein said transducer mount further comprises:
- a channel defined through said housing structure from an upper rim of said housing to a lower rim of said housing; and
- said transducer supporting means being mounted within said channel, displaced from said lower rim.
- 4. Apparatus of claim 3, further comprising:
- a flexible membrane bordering said channel adjacent said lower rim and displaced from said transducer support means, defining a couplant chamber within said channel between said membrane and said transducer supporting means; and
- coupling material occupying said couplant chamber.
- 5. Apparatus of claim 4, wherein said transducer supporting means comprises an annular rim mounted within said channel, a ball member mounted for movement in said annular rim and a threaded cylindrical passage formed through said ball member; wherein said transducer search unit comprises a cylindrical body, a head end of said body, and external threading on said body; and wherein said search unit is threaded into said passage of said ball member with said search unit head immersed in coupling material within said coupling chamber, whereby as the ball member moves, the search unit moves within the housing structure while the head remains immersed in the couplant material.
- 6. Apparatus of claim 5, wherein said transducer mount further comprises:
- anti-skid means associated with said housing structure for resisting slippage of said transducer mount on the conduit; and
- strap means for strapping said transducer mount to the conduit.
- 7. Ultrasonic searching apparatus for use in locating an object within a casing, said apparatus comprising:
- a transducer mount for placement against the casing, said transducer mount comprising a housing structure and a transducer supporting means for supporting a transducer search unit for movement within said housing structure;
- a transducer search unit held by said transducer supporting means, which search unit transmits an ultrasonic signal beam;
- beam representing member oriented parallel to the centerline of said signal beam;
- plumb means suspended from said beam representing member for defining a vertical axis;
- first protractor means for indicating the angle between said beam representing member and said vertical axis;
- Z axis reference member for orientation in a vertical plane which plane is parallel to the direction of a chosen Z-axis; and
- second protractor means for indicating the angle between said beam representing member and said Z-axis reference member.
- 8. Apparatus of claim 7, wherein said Z-axis reference member is suspended from said plumb means in a horizontal plane.
- 9. Apparatus of claim 7, wherein said transducer mount further comprises:
- a channel defined through said housing structure from an upper rim of said housing to a lower rim of said housing; and
- said transducer supporting means being mounted within said channel, displaced from said lower rim.
- 10. Apparatus of claim 9, further comprising:
- a flexible membrane bordering said channel adjacent said lower rim and displaced from said transducer support means, defining a couplant chamber within said channel between said membrane and said transducer supporting means; and
- coupling material occupying said coupling chamber.
- 11. Apparatus of claim 10, wherein said transducer supporting means comprises an annular rim mounted within said channel, a ball member mounted for movement in said annular rim and a threaded cylindrical passage formed through said ball member; wherein said transducer search unit comprises a cylindrical body, a head end of said body, and external threading on said body; and wherein said search unit is threaded into said passage of said ball member with said search unit head immersed in couplant material within said couplant chamber, whereby as the ball member moves, the search unit moves within the housing structure while the head remains immersed in the couplant material.
- 12. Apparatus of claim 11, wherein said transducer mount further comprises:
- anti-skid means associated with said housing structure for resisting slippage of said transducer mount on the casing; and
- strap means for strapping said transducer mount to the casing.
