摘要： A method and apparatus which uses ultrasonic techniques to inspect critical pipe joints and other critical industrial areas that are normally inaccessible. A waveguide (20, 46) including one or more flexible fibers (72) is embedded in concrete (12) or whatever else embeds the piping which includes the critical area. One end of the waveguide (20, 46) is accessible so that an ultrasonic transducer (30) can be used to transmit ultrasonic signals along the waveguide (20, 46) and receive reflected echoes to provide an ultrasonic image of the critical area. In a case where the area to be inspected is submerged, the waveguide (20, 46) takes the form of a flexible fiber bundle which is manipulated until its end is adjacent to the critical area. Some of the fibers (72) in the bundle can be used to illuminate the critical area, and other fibers (72) can transmit optical images for display on a video monitor (78).

摘要： A method and apparatus for sizing a surface-connected planar crack (8) through a gas- or liquid-filled gap (32). Ultrasonic energy having a frequency equal to the resonant frequency of the gap is emitted toward the crack edge (24). A first portion of the energy is back-scattered by the crack edge toward the emitter (at 20) in a detection mode and a second portion is scattered by the crack edge toward a surface (18) to which the crack is connected, which reflects the second portion toward a detector (at 30). The difference between the respective times-of-flight from emission to detection of the first and second portions is measured and used to determine the depth of penetration of the surface-connected crack. The paths traveled by the first and second portions of said emitted ultrasonic energy substantially intersect at the gap. A similar method also applies in sizing buried planar cracks (8') across fluid-filled gaps.

摘要： A probe for ultrasound testing or treatment of a molten metal comprises: an ultrasound transmitting rod (10) of which one end is a "downstream" end (12) adapted to contact molten metal under test or treatment; a piezoelectric crystal (50) adapted to supply ultrasound to or receive ultrasound from the rod (10); and rod-cooling means (16) located near to the downstream end (12) of the rod (10). A method for the treatment of a liquid metal melt, to reduce the number of inhomogeneous particles distributed through the melt comprises: creating a standing wave of ultrasound energy within the melt, e.g. using a probe as defined above, whereby the inhomogeneous particles concentrate, and are encouraged to coalesce, at the nodes of the standing wave; and separating the coalesced particles from the bulk of the liquid melt.

摘要： Cast metal billets are transported on a conveyor beyond a testing unit and are tested with regard to defects by means of ultrasonic probes which respectively are mounted in guide or coupling shoes. The coupling shoes rest on the billets during the testing operation, and a liquid is supplied between the coupling shoes and the billets to provde the necessary contact between the shoes and the billets. Impulses emitted by the testing unit activates a marking device which automatically marks the billets where defects are detected.

摘要： The ultrasonic detector comprises an ultrasonic sound generator (54) and an ultrasonic sound receiver, each having a substrate (58) with at least two isolated regions (64, 66) of a layer (60) of electrically conductive material located thereon. A piezoelectric chip (72) electrically contacts the first region (64) of the conductive layer (60) and a conductive member (74) extends between the the chip (72) and the second region (66) of the conductive layer (60). An electrical signal having a frequency of the resonant frequency of the chip (72) can be applied between the first and second regions (64,66) to cause ultrasonic sound to be generated, whereby ultrasonic sound received by the chip (72) can be electrically detected by monitoring the electrical signal produced between the first and second regions (64,66).

摘要： An ultrasonic linear array water nozzle (10, 10A) wherein water is coupled with ultrasonic energy between linear array transducers (126) and a workpiece (132) under inspection. The nozzle includes a water receiving plenum chamber (22) extending for the length of the nozzle and for the length of linear array transducers. Plenum chamber (22) supplies water immediately downstream of the transducers where water is coupled with ultrasonic energy from the transducers. The nozzle has a main body (88) downstream of the transducers and has downstream water paths in the form of waveguides (190) which are spaced by air gaps (186), the waveguides each extending downstream in the shape of an exponential horn. The waveguides (190), formed by consecutive plates (168) having air gaps (186), are each in respective alignment with an individual transducer (126).

摘要： A probe (20) for longitudinally traversing and circumferentially inspecting the interior of a tube. A rotating sensor containing head (44) is driven by a rotor (40) extending from the end (38) of a cylindrical housing (12) in which it is mounted. The axially fixed rotor (40) surrounds and is driven by a helix drive connection (70) to a piston extension (36). The piston (20) reciprocates in a cylindrical chamber (14) within the housing (12) in response to selectively applied fluid pressure acting against a spring bias (60). A strain gage (62) on the spring (60) controls the fluid pressure by means of valve (2) whereby reciprocation of the piston (20) and its extension (32) rotates the rotor (40) by means of the helical groove (72) and balls (74). The various parts are hollow to accommodate the necessary wire conductors (51 and 64) and H₂O.

摘要： 57 Method and apparatus for ultrasonically inspecting coextruded plastic sheet as it is produced. The apparatus comprises means for supporting a section of sheet in position to be inspected, and means for supporting transducer means in contact with the surface of said sheet. The transducer means comprises at least one housing supporting an ultrasonic transducer and defining a chamber between the face of the transducer and the surface of the sheet. The chamber is filled with an interfacing fluid so that ultrasonic pulses from the transducer will pass through the fluid into the sheet to be reflected from any interface therein. The transducer means and interfacing fluid are moved across the surface of the sheet to permit inspection of the entire sheet. Thus, it is unnecessary to submerge the sheet in a vat of interfacing liquid or to bend or otherwise deform, and possibly damage, the sheet as is done in current systems. The apparatus further includes means within said chamber for directing interfacing fluid substantially transversely across the face of the transducer for washing away any air bubbles that may form in the interfacing fluid between the transducer and the surface, together with means for maintaining a substantially continuous flow of the fluid thereacross. The ultrasonic pulse echoes received from the sheet are analyzed to provide an indication of the presence and thickness of layers therein.
