Latest Patents

Patsfall's latest patents include a design and processing method for manufacturing hollow airfoils. This innovative method involves preforming three metal sheets into initial shapes and sealing them together to create an in-process assembly. Internal cavities are formed in the assembly prior to sealing, and the assembly is subjected to high temperature and pressure to diffusion bond the sheets together at selected points. The cavities are then inflated and superplastically deformed to achieve the desired shape, with excess material machined off after inflation. Another significant patent is for an apparatus for bonding an article projection. This method involves repairing or manufacturing an article, such as a bladed disk, by first removing a damaged projection to create a stub. A collar is then bonded to the stub, followed by the bonding of a replacement or new projection member to complete the article.
