Publication number: 20220074317Abstract: A rotor shaft for a high speed motor that has a coating that is secured to a shaft body. The coating and the shaft body are formed from dissimilar materials. More specifically, the coating may be an alloy material, such as, for example, a copper alloy, while the shaft body may be a steel material. According to certain embodiments, the alloy material of the coating may be secured to at least a portion of a rotor body blank in a solution treated condition via a low temperature welding procedure. Additionally, the coating may be hardened, such as for example, through the use of an age hardening process. The coating and the rotor body blank may be machined together to form the rotor shaft. According to certain embodiments, such machining may configure the rotor shaft for use with a turbo-compressor that is configured for air compression.Type: ApplicationFiled: September 21, 2021Publication date: March 10, 2022Inventors: James Lawrence Robb, Juha Tuomas Saari, George C.

Patent number: 9991588Abstract: A highly conductive fiber reinforced tubular antenna is composed of metal coated reinforcing fibers in a composite structure. The conductive fibers may be disposed in a tubular or cylindrical fashion unidirectionally parallel to or at an angle to the axis of the tube or cylinder, thus providing multifunctional properties of strength and conductivity. Alternatively, the conductive fibers may be non-woven in configuration and disposed on one or more wrapped layers to form the antenna. The fiber reinforced composites disclosed are both lighter and stronger than their metal counterparts, while the highly increased conductive surface area in the composite creates enhanced electrical or electromagnetic performance than tubular or cylindrical antennas made of metal or nonmetal composite structures.Type: GrantFiled: September 24, 2013Date of Patent: June 5, 2018Assignees: CONDUCTIVE COMPOSITES COMPANY, NORTH FORK COMPOSITES, LLCInventors: George C.
