Latest Patents

One of John K. White's latest patents is the "Eddy current apparatus including cylindrical coil with flux concentrator." This apparatus is designed for testing flaws in conductive objects. It features a coil of electrically conducting wire and an associated flux concentrator made of electromagnetically active material. This design provides a desired resolution of flaw detection and ensures close coupling between the coil and the conductive object. An associated bridge circuit detects changes in the coil's impedance, which are caused by flaws in the object, and activates a display to visually indicate these changes.

Another significant patent is the "Ultrasonic nondestructive tubing inspection system." This apparatus is specifically aimed at inspecting tubing, particularly for determining the extent of erosion in the walls of heat exchange tubes in nuclear reactors. The system includes an ultrasonic transducer assembly that is movable axially and rotatably in a helical path. This movement produces both thickness and position signals, allowing for a comprehensive map of wall thickness.
