Title: Mark Lieberman: Innovator in Recycling and Dental Technology

Introduction

Mark Lieberman is an accomplished inventor based in Bloomfield Hill, MI (US). He has made significant contributions to the fields of recycling and dental technology. With a total of 3 patents to his name, Lieberman continues to push the boundaries of innovation.

Latest Patents

One of Lieberman's latest patents is a thermoplastic closed loop recycling process. This innovative process includes the step of testing particulated processed plastic material to determine its properties. The tested properties are compared with targeted near virgin properties of the processed plastic material to identify any differences. Additives based on the property differences determined during testing are mixed with the particulates in a twin screw extruder. During the extrusion process, volatile constituents are simultaneously withdrawn from the fused particulates. The twin screws of the extruder are designed with various screw sections, each featuring a thread with predetermined degrees of chamfer and pitch length. Kneading blocks are mounted on certain screw sections prior to a vacuum vent port along the feed path of the melt stream in the extruder. The extruded material is then tested to determine if any property differences exist. If no unacceptable differences are found, the extruded material is prepared for reuse alongside virgin plastic material that has the same properties and characteristics.

Another notable invention is the radiolucent dental dam clamp. This innovative dental tool enhances the efficiency and effectiveness of dental procedures.
