Title: Innovations of Joseph A. Biesenberger
Introduction
Joseph A. Biesenberger is a notable inventor based in Wayne, NJ (US). He has made significant contributions to the field of thermoplastic foams and mixing apparatuses. With a total of 2 patents, his work showcases innovative methods that enhance material processing.
Latest Patents
One of Biesenberger's latest patents is a method of preparing thermoplastic foams using a gaseous blowing agent. This process involves injecting a gaseous blowing agent, such as nitrogen, air, carbon dioxide, or argon, into a melted thermoplastic polymer. The pressure is carefully controlled to form a solution of the blowing agent and the melted polymer. The solution is then cooled to a temperature close to the polymer's freezing point while maintaining specific pressure conditions. This ensures that the thermoplastic foam produced has at least 65% closed cells by volume and a uniform cell size. The cooled solution is extruded through a die, resulting in a cellular product.
Another significant patent is the back mix drag-flow apparatus. This apparatus provides both radial and axial mixing of materials through the use of at least two worms in screw form. These worms can be arranged in parallel and tangential configurations, either rotating in the same direction or in opposite directions. The design includes a barrel casing that encloses the worms and features a feed inlet and a product outlet.
