Latest Patents
One of Larson's latest patents is a method of cold working holes using a shape memory alloy tool. This invention enhances the fatigue lifetime of holes formed in structural members by introducing a cold working tool or interference fit fasteners made from shape memory alloy materials. The tool expands the wall of a hole when heated above a critical transitional temperature and contracts upon cooling, allowing for easy withdrawal. This method ensures that bushings and interference fit fasteners can be installed effectively, thereby improving the fatigue life of structural members.
Another significant patent is the computerized multi-zone crystal growth furnace. This heating system features a cylindrical hollow muffle made of alumina ceramic, surrounded by heat-generating windings. A light-actuated power control is connected to these windings, while a computer monitors the temperature of the article being heated. This precise temperature control is crucial for the fabrication of crystals with uniform properties, making the system particularly valuable for specialized growth requirements.
