Title: Innovations by Joseph W. Brophy
Introduction
Joseph W. Brophy is a notable inventor based in San Antonio, TX (US). He has made significant contributions to the field of pipe and tube inspection technology. With a total of 2 patents, his work focuses on improving the methods used to assess the integrity of cylindrical structures.
Latest Patents
Brophy's latest patents include a "Method for determining average wall thickness for pipes and tubes using ultrasonic and/or magnetostrictive wave probes." This innovative method analyzes the dispersive behavior of waves traveling in the tube wall volume. It examines specific wave propagation modes and identifies a cut-off frequency that is characteristic of a particular wall thickness or tube diameter. This technique allows for rapid and accurate inspection of pipes and tubes from a single location on the inside diameter, enabling comparisons with original condition data. Changes in the cut-off frequency, as determined by this method, are inversely related to changes in wall thickness and mean radius, providing a mechanism for assessing the remaining service life of such structures.
Another significant patent is the "Apparatus and method for inspection of pipes and tubes using guided wave." This invention directs ultrasonic and magnetostrictively generated mechanical waves from an exterior point to an interior point within small diameter tubes or pipes. It incorporates an external mechanism for generating waves in a cylindrical waveguide tube, which is small enough for insertion into the target tube. The design maintains mechanical contact with the inside diameter of the target tube, allowing for effective inspection. The system includes sensor devices that receive returned signals and interpret impedance mismatches, indicating flaws and geometric variations in the tubular wall.
