Title: The Innovative Contributions of Daniel Gregory Tynan
Introduction
Daniel Gregory Tynan is a notable inventor based in Wilmington, DE (US). He has made significant contributions to the field of polymer technology, holding a total of 12 patents. His work focuses on developing advanced mixing apparatuses and processes for polymers, which have applications in various industries.
Latest Patents
Among his latest patents is the "Polymer mixing apparatus and method." This invention features a mixing apparatus designed for mixing and conveying solid, particulate, polymeric materials. It includes a barrel that can be heated and cooled, along with at least two co-rotatable, self-wiping extruder screws. These screws are connected through a laterally flexible coupling to a drive means that can reverse their rotation direction when a predetermined event occurs. The apparatus also has a closeable feed port and discharge port, both capable of being made gas-tight, with seals that withstand elevated gas pressures inside the barrel.
Another significant patent is the "Staged feeding process for mixing polymers." This process prepares a composition by mixing at least a first polymer and a second, dissimilar polymer. It results in a final composition that comprises a uniform, small-particle dispersion of the first polymer within a matrix of the second polymer. The process involves feeding the first polymer in a first feed stage and the second polymer in at least two subsequent feed stages, initiating a chemical reaction between the two polymers.
