Title: Thomas J Crossley: Innovator in Nuclear Technology and Chemical Separation
Introduction
Thomas J Crossley is a notable inventor based in Littleton, CO (US), recognized for his contributions to nuclear technology and chemical separation processes. With a total of 4 patents, Crossley has made significant advancements in the field, particularly with his innovative designs and methods.
Latest Patents
One of Crossley's latest patents is the "Dual seal nozzle dam and alignment means therefor." This invention provides a fluid-tight seal across a primary fluid nozzle in the plenum of a nuclear steam generating vessel. The design includes two fluid-impermeable seals, each featuring a circular three-section foldable seal plate covered with a flexible diaphragm. These seals are circumferentially encompassed by an inflatable seal member, which engages the inner surface of the nozzle. The apparatus is interconnected by a central tubular coupling that allows for quick disconnection and inflation of one of the seals. Additionally, the structure includes mechanisms for pressurizing and monitoring the inter-seal space.
Another significant patent is the "Method of separating molybdenum from uranium." This method involves lowering the pH of an aqueous solution containing uranium and molybdenum using an inorganic acid, such as hydrochloric acid. After removing carbon dioxide from the solution, the pH is raised in the presence of ammonium ions, leading to the precipitation of ammonium diuranate. This precipitate can then be filtered or separated from the remaining molybdenum in the solution.
