摘要： An apparatus for ultrasonic inspection of an object. A tire is mounted for rolling along the surface of the object. It contains a liquid and a transducer assembly. The transducer assembly is positioned in the tire adjacent a portion of the surface of the tire in contact with the object. The liquid and the surface of the tire in contact with the object provide an acoustic bridge between the transducer assembly and the object. An electric signal processing system is connected to the transducer assembly. It generates electric signals which are converted to acoustic signals in the transducer assembly to place acoustic signals in the object. Acoustic signals returned from the object are converted to electric signals by the transducer assembly, and are processed in the electric signal processing system to indicate flaws in the object.

摘要： A system of transducers and electrical circuitry connecting with the transducers detects and locates flaws in the metallic walls of vessels used for containing and transporting liquids. An array of transducers is carried by a sled having rollers for facile movement about the surface of the vessel which surface is submerged within the liquid to permit the liquid to provide a sound propagating medium between the transducers and the vessel wall. The transducers are arranged in sets of two transducers, one of which is a transmitting transducer and the other a receiving transducer, the two transducers being positioned in tandem for increased azimuthal coverage of the sonic radiation.

摘要： A system for testing the fabrication of objects utilizes echo-sounding techniques. A transmit transducer and a receive transducer which provide a conversion between electric and sonic energies are acoustically coupled to the object under test. A single cable connects the transducers to a single processor which generates, receives and analyzes the signals utilized in the test process. A coupling circuit connects one end of the single cable to the two transducers and isolates a transmitted signal from a received signal so as to permit their communication by the single cable. Within the coupling circuit, a transmitted signal is communicated by a set of serially connected diodes wherein the forward voltage drop is much less than the voltage of the transmitted signal, but greater than the voltage of an incoming signal such as a reverberation of the transmitted signal or a received echo signal. The second channel of the coupling circuit provides for a series connection of a resistor with a set of parallel diodes connected with opposed polarity, the diodes being connected across the terminals of the receive transducer.

摘要： A search unit for detecting internal flaws in the web of a railroad rail includes a plastic polymer shoe having a base surface contoured to conform generally to the web surface and of sufficient width to extend substantially across the width of the web. A plurality of dual ultrasonic transducers, each transducer including a transmitter and a spaced receiver, form a linear array across the width of the shoe and are angled with respect to each other. A couplant fluid is injected between the shoe and the rail web through fluid inlets in the shoe as the unit is slid along the rail.
