Latest Patents

One of his notable inventions is the "Center-feed nozzle in a contained cylindrical feed-inlet tube for improved fluid-energy mill grinding efficiency." This invention relates to a supersonic center-feed nozzle system within the feed-inlet tube of a fluid-energy mill used for grinding particulate material such as titanium dioxide. In this design, particulate material is introduced into the supersonic feed jet of primary grinding fluid in a nearly perpendicular manner. The supersonic nozzle is installed at the center of the particulate material core, imparting momentum to the material, which is then entrained into the main grinding chamber. A secondary stream of grinding fluid is introduced annularly to enhance turbulent mixing, leading to improved grinding efficiency.

Another significant patent is the "Preparation of organic additive-treated, pyrogenic silica-encapsulated titanium dioxide particles." This invention provides a composition comprising titanium dioxide particles with a substantially encapsulating layer of pyrogenically-deposited metal oxide. The layer features at least one organic surface treatment material, which can include various compounds such as organo-silanes, organo-phosphonates, and hydrocarbon-based acids. This innovation not only enhances the properties of titanium dioxide but also outlines processes for producing the composition.
