Title: The Innovations of Alfred J Martenson
Introduction
Alfred J Martenson is a notable inventor based in Richland, WA (US), recognized for his contributions to the fields of material processing and nuclear technology. With a total of two patents to his name, Martenson has made significant advancements that showcase his innovative spirit and technical expertise.
Latest Patents
Martenson's latest patents include a process for expanding obsidian and a device designed for the expansion of nuclear fuel assemblies. The process of expanding obsidian involves heating obsidian with less than one percent of combined water in a two-stage heating process within a refractory-lined rotary kiln. The first stage gradually heats the material to temperatures between 1800-1900°F, followed by a second stage that subjects it to temperatures of 2400-2500°F for a brief period. This method ensures that the softened obsidian does not stick to itself or the kiln lining, thanks to the presence of dust with a high softening point. In another embodiment, the process can be executed in a single kiln or through a two-kiln system where combustion gases are recycled to aid in heating.
The second patent, a device for the expansion of nuclear fuel assemblies, features an upper tie plate assembly that includes a tie plate with holes for tie rods. The design incorporates lower and upper side members, leaf springs, and sliders that engage with the upper core plate of the reactor. This innovative arrangement allows for the expansion of the fuel assembly while maintaining unobstructed flow of cooling water, thus preventing undesirable stresses in the springs.
