Title: Vincent Hervais: Innovator in Thermoplastic Cooling Processes
Introduction
Vincent Hervais is a notable inventor based in Bully-les-Mines, France. He has made significant contributions to the field of thermoplastic materials, particularly in cooling processes. With a total of 2 patents to his name, Hervais has developed innovative methods that enhance the production and quality of thermoplastic products.
Latest Patents
Hervais's latest patents include a "Process for cooling a tubular sleeve of thermoplastic material" and a "Process and device for cooling a tubular sleeve produced by hot extrusion-blowing of a thermoplastic material through an annular die." In these processes, a stream of primary air is flowed under pressure, substantially parallel to and spaced from the tubular sleeve, reaching the sleeve at a second stage. This stream induces a secondary air flow that is laminar over most of its path. The device features a first cylindrical sleeve member that, in combination with the tubular sleeve, defines a secondary air flow space. Additionally, a second cylindrical sleeve member and the first sleeve member create a primary air flow space. A cylindrical ring near the annular die directs air into the secondary air flow space, while a source of pressurized air is in flow communication with the primary air flow space.
Career Highlights
Throughout his career, Vincent Hervais has worked with several companies, including Société Chimique des Charbonnages and Société Anonyme des Charbonnages. His work has focused on improving the efficiency and effectiveness of thermoplastic production processes.
