Title: The Innovative Contributions of Carl K Johnson
Introduction
Carl K Johnson is a notable inventor based in Manchester, Connecticut, who has made significant contributions to the field of engineering through his innovative patents. With a total of 3 patents to his name, Johnson has focused on developing advanced methods that enhance the efficiency and effectiveness of various technologies.
Latest Patents
One of Johnson's latest patents is the "Uniform Braze Application Process." This method involves forming thin, uniform braze joints using curtain coating. In this process, braze powder is mixed with a liquid polymeric binder to create a slurry. The slurry is then forced through slots in a curtain coating head and deposited on the metal surfaces to be bonded. This technique is particularly useful for bonding fin/plate sections of heat exchangers, ensuring maximum contact for high heat transfer and strong joints.
Another significant patent is the "Method for Producing a Fuel Cell Manifold Seal." This invention addresses the challenge of maintaining a low leak rate in manifold seals for fuel cell stacks. The seal system is designed to prevent sliding against rough surfaces as the stack undergoes compressive creep. By utilizing a polymer seal frame that moves with the stack, the invention ensures a reliable seal without the issues associated with relative motion.
