The present invention is directed to solving the problems associated with the detection of surface defects on metal bars as well as the problems associated with applying metal flat inspection systems to metal bars for non-destructive surface defects detection. A specially designed imaging system, which is comprised of a computing unit, line lights and high data rate line scan cameras, is developed for the aforementioned purpose. The target application is the metal bars (1) that have a circumference/cross-section-area ratio equal to or smaller than 4.25 when the cross section area is unity for the given shape, (2) whose cross-sections are round, oval, or in the shape of a polygon, and (3) are manufactured by mechanically cross-section reduction processes. The said metal can be steel, stainless steel, aluminum, copper, bronze, titanium, nickel, and so forth, and/or their alloys. The said metal bars can be at the temperature when they are being manufactured. A removable cassette includes various mirrors. A protection tube isolates the moving metal bar from the line light assembly and image acquisition camera. assembly and image acquisition camera. A contaminant reduction mechanism applies a vacuum to remove airborne contaminants.

Systems and methods for determining an inconsistency characteristic of a composite structure, such as inconsistency density-per-unit area In one implementation, a method is disclosed for determining an inconsistency characteristic of a composite structure The method involves determining a first distance from a first reference point of the composite structure to an inconsistency; determining a second distance from a second reference point of the composite structure to the inconsistency; using the first and second distances to establish a reference area of the composite structure; and considering each inconsistency detected within the reference area and producing therefrom an inconsistency characteristic representative of the composite structure

A leak detection structure for attachment to a fire hydrant includes an enclosure, the enclosure defining a cavity internal to the enclosure and a leak detection subassembly located in the cavity, the leak detection subassembly including at least one leak detection sensor and at least one circuit.

Enclosure for leak detector

This invention relates to a Electromagnetic Acoustic Transducer which has the ability to detect flaws in assorted metallic objects, such as pipes, rods, bars and the like, including those objects which are already installed and cannot be removed without a major undertaking. The Transducer also has an embodiment which includes hinged arms for surrounding the circular objects that have already been installed such as piping. The system employs Lamb waves to move along the surface of metallic objects to affect a bounced return to thereby allow detection of flaws on the surface or in the interior of said objects.

Transducer guided wave electromagnetic acoustic

A EMAT inspection system is utiliized on sheet metal prior to it being formed or rolled to identify surface defects and sub-surface defects such as pencil pipe inclusions by using ultrasonic Lamb waves with the results being displayed on a remote screen of a display and control system which also records the inspection results and controls the EMAT system.
