Title: Dean Alhorn and High-Temperature Sealing Innovation.
Introduction
Dean Alhorn is an inventor associated with Huntsville, Alabama, and Raytheon Company. His patent work addresses the challenge of sealing an axially expanding volume operating at high temperatures.
Latest Patents
Alhorn is credited with 1 patent: “High Temperature Sealing System for an Axially Expanding Volume.” The invention uses a piston seal rated for temperatures below the volume’s operating temperature, supported by two backup sealing stages. Its primary backup seal uses opposing wedge-shaped rings that move axially together and radially apart, closing a gap and creating a tortuous path to impede liquefied piston-seal material. A secondary backup seal is a metal face seal positioned at the end-of-travel stop.
Career Highlights
Alhorn’s listed patent reflects work on layered sealing protection for high-temperature applications. His association with Raytheon Company connects this engineering contribution to a company active in advanced technology and aerospace-related fields.
Collaborations
The available information identifies Raytheon Company as Alhorn’s employer but does not specify collaborators or co-inventors for the patent.
Conclusion
Dean Alhorn’s patent describes a multi-stage sealing system designed to help protect an axially expanding volume under high-temperature operating conditions.
