SIUI develops and manufactures a variety of ultrasound imaging systems and accessories for both human and veterinary use, and NDT equipment including phased-array ultrasonic flaw detector, [3] conventional flaw detector, [4] thickness gauge, probes [5] and accessories. The company is currently organized into three product category divisions ...
The patent is granted on April 21, 1942 as U.S. Patent No. 2,280,226, titled "Flaw Detecting Device and Measuring Instrument". Extracts from the first two paragraphs of the patent for this entirely new nondestructive testing method succinctly describe the basics of such ultrasonic testing.
Weld examination by phased array. TOP: The phased array probe emits a series of beams to flood the weld with sound. BOTTOM: The flaw in the weld appears as a red indication on the instrument screen. Phased array ultrasonics (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive ...
Since then, many other inspection cars have traversed the rails in search of flaws. In 1949 ultrasonic flaw detection was introduced by Sperry Rail Service (Named after Dr. Elmer Sperry), by the 1960s Ultrasonic Inspection Systems had been added to the entire Sperry Fleet. Rail inspection continues to advance to this day.
Peanut Butter Blossoms. As the story goes, a woman by the name of Mrs. Freda F. Smith from Ohio developed the original recipe for these for The Grand National Pillsbury Bake-Off competition in 1957.
Researchers from the federal energy department's Pacific Northwest National Laboratory found that drones have the potential to conduct detection of low levels of radiation across survey sites, but ...
If the material contains a crack or flaw which make the spatial distribution of the electrical conductivity nonuniform, the path of the eddy currents is perturbed and the impedance of the coil which generates the AC magnetic field is modified. By measuring the impedance of this coil, a crack can hence be detected.
