Latest Patents
Among his latest patents, the "Modified Nozzles for Polymer Finishers" stands out. This invention involves an apparatus designed to separate entrained matter from a flowing fluid. The apparatus features a passage that diverges at an angle of 3 to about 20 degrees in the direction of fluid flow, along with at least one helical flight that maintains a consistent twist direction. Additionally, a straight cylindrical pipe is attached to the outlet end of the passage, which contains a straight baffle interlocking at about 90 degrees with the helical flight. The design allows for the edges of the flight to be either spaced from or in contact with the wall of the diverging passage.
Another significant patent is the "Diamine Recovery Process." This innovation improves the efficiency of a rectifying zone for recovering diamine vapor from water vapor. The process involves adding a dicarboxylic acid to the reflux water at the top of the rectifying zone, which enhances the separation of vapor from a reaction zone where a polyamide-forming salt is heated to create a prepolymer.
