Latest Patents

Larsen holds a patent for a "Metallic coating for a cadmium fuse." This invention is designed to interrupt all values of electric current in a high voltage circuit, ensuring the operation of a fuse within one hour. The patent describes a system where a plurality of parallel connected helically configured fusible elements made of cadmium are embedded within quartz sand. This setup is housed within a tubular member of insulating material, which is equipped with terminal caps connected to the fusible elements. The design allows for the interruption of high magnitude currents in a fraction of a half cycle while also managing lower magnitude currents effectively. To prevent degradation of the cadmium fusible elements, a non-porous metallic coating of uniform thickness is applied, ensuring no inter-metallic diffusion occurs at temperatures below cadmium's melting point. Larsen's innovative approach has resulted in a significant advancement in fuse technology.
