Title: Christopher William Bumby: Innovator in Superconducting Technology
Introduction
Christopher William Bumby is a notable inventor based in Wellington, New Zealand. He has made significant contributions to the field of superconducting technology, holding a total of 3 patents. His innovative work focuses on enhancing the efficiency and functionality of superconducting systems.
Latest Patents
One of Bumby's latest inventions is the superconducting switch. This invention relates to a superconducting electrical switch that comprises two parallel branches of superconducting material in a loop. A magnetic field generator is employed to create a time-varying magnetic field through the loop, allowing the switch to toggle between a low-resistance state and a higher-resistance state. In the low-resistance state, there is no magnetic field, enabling transport current to flow freely. Conversely, in the higher-resistance state, the magnetic field induces a screening current, which can be utilized in applications such as rectifiers or fault current limiters.
Another significant patent is the superconducting current pump. This device is designed to facilitate a DC electrical current flow through a superconducting circuit housed within a cryogenic enclosure. The pump features a rotor located outside the cryogenic enclosure and a stator within it, separated by a thermally insulating wall. The design minimizes heat leakage, ensuring that the cold components within the cryogenic enclosure maintain the low operating temperatures necessary for optimal performance.
