Latest Patents

One of Hanley's latest patents is titled "Method and apparatus for conducting in-situ nondestructive tensile load." This invention provides an apparatus and method for the non-contact measurement of tensile loading in ferromagnetic materials, such as wire ropes, cables, and strands. The technology utilizes the magnetostrictive effect to measure wave propagation properties within these materials, allowing for the determination of load forces based on a signature obtained from similar materials under like conditions. The system includes an active measurement application where a transmitting sensor generates a mechanical pulse within the material, and a receiving sensor detects reflected mechanical waves, all without direct physical contact.

Another significant patent is the "Method and means for detection of hydrogen attack by ultrasonic wave." This method employs ultrasound wave velocity measurements to detect hydrogen attack in steel bodies, such as pipes. By transmitting ultrasound waves and measuring their velocity with high accuracy, Hanley’s invention can identify a decrease in velocity that indicates potential hydrogen attack. The method includes various embodiments, such as using refracted longitudinal or shear waves, and measuring backscattered ultrasound to assess material integrity.
