Latest Patents
One of his latest patents is titled "Method for forming microporous fluorocarbon polymer sheet and product." This invention describes a method for creating a microporous sheet of fluorocarbon polymer, specifically polytetrafluoroethylene. The process involves forming an aqueous dispersion of polytetrafluoroethylene with a dissolved water-soluble, crystallizable metallic organic salt, such as sodium benzoate. By evaporating water from the sheet's surface, crystals of the organic salt grow throughout the sheet. The sheet is then sintered, and after cooling, the salt crystals are leached out by dissolving them in water, resulting in a porous structure suitable for applications like filtration membranes or separation barriers in batteries.
Another notable patent is for a "Non-clogging microporous filter with cross flow operation." This invention features a microporous filter equipped with a pleated filter cartridge. It includes inlet and bypass ports that establish tangential flow across the outside boundary of the cartridge's inlet side, leading to a slow clogging operation. This design enhances the efficiency and longevity of the filtration process.
