With a total of 6 patents to his name, Rigby's work has had a considerable impact on various technological applications.

Latest Patents

One of Rigby's latest patents is a method of making low wear glass for magnetic heads. This innovative glass is created by combining a specific lead borosilicate glass with a specific borosilicate glass in a 60/40 weight percent ratio. The resulting glass exhibits compatibility with ferrite and demonstrates reduced wear characteristics. By controlling the anneal temperature, Rigby has provided a means to regulate the residual stress of the closure glass, thereby enhancing its wear properties.

Another significant patent involves the process of hot isostatic pressing of ferrite material. This process allows for the production of MnZn ferrite material that approaches theoretical density without a significant increase in grain size. The method includes pressurizing an entire ferrite sample surrounded by similar composition pieces while in alumina crucibles. By introducing an inert atmosphere and elevating pressure and temperature, Rigby optimizes density while maintaining or improving the magnetic properties of the ferrite.
