Latest Patents

One of Prenn's latest patents, titled "Process for upset forging of long stands of metal bar stock," describes a method and apparatus capable of upset forging a long stand of solid malleable metal bar stock in a single pass. This invention is designed to gather a large volume of bar stock into a complex shaped element. The process involves selectively heating the end of the bar stock to achieve two different forging temperatures in various sections. The heated bar is then positioned in an upset forging die cavity, where a forging punch enters to upset the long stand, effectively filling the cavity with the heated sections. Additional friction-reducing materials in the cavity facilitate the process by allowing a smooth movement while the end section upsets and gathers the intermediate section.

Another of his noteworthy inventions is the "Composite electrode with non-consumable upper section," which features a metallic, water-cooled upper portion and a consumable lower portion. This innovative design includes conduit means to ensure that cooling water or other liquids maintain intimate contact with the inner surfaces of the upper portion, thereby improving efficiency during use.
