Latest Patents

Corcoran is credited with 1 patent: “Apparatus and a Method of Ultrasonically Inspecting a Component.” The invention describes an apparatus designed to inspect a gas turbine engine component ultrasonically at a required centre frequency.

The apparatus includes an ultrasonic transducer and a waveguide mounted in a holder. The holder moves within a carrier, which in turn moves within a frame. The waveguide has a circular cross-section, a concave surface between its ends, and a diameter that decreases from the first end to the second. Its length is between 0.5 and 3 times the wavelength of an ultrasonic signal at the inspection’s required centre frequency.

Career Highlights

The patent reflects Corcoran’s work on inspection equipment for gas turbine engine components. Its adjustable mounting arrangement and specified waveguide geometry are central features of the disclosed design.

Collaborations

The provided information identifies Alejandro Jeketo and Eli Leinov as Corcoran’s coworkers. It does not specify their roles in the patent or the nature of their collaboration.

Conclusion

Joseph J. Corcoran’s patent focuses on an ultrasonic inspection apparatus with a carefully defined waveguide and movable mounting system for examining gas turbine engine components.
