David M Dickens is an accomplished inventor based in Sunnyvale, CA. He holds a total of 3 patents that showcase his expertise in heating technologies. His innovative contributions have made significant impacts in various industries.
Latest Patents
One of his notable inventions is the dual surface heater. This device features two parallel temperature self-regulating heater plates or wire mesh made from ferromagnetic material. It includes one or more electrically energized coils that are positioned parallel to and located between the heater plates. When energized by a constant or controlled current, these coils heat the plates to their Curie temperature. The design incorporates a flat spiral of thin conductive copper wire embedded in a heat conductive, electrically non-conductive material. This setup allows the heat energy generated in the coil to be effectively supplied to the heater plates. The dual plate heater is particularly useful for heating plastic pipes to their butt welding temperatures, after which the heater can be removed, allowing the ends of the pipes to be joined under pressure. Additionally, these heaters can be utilized in various arrangements, such as shelves in dispensing machines.
