Title: Innovations by Inventor Frédéric Cottais

Introduction

Frédéric Cottais, a talented inventor based in Lezoux, France, has contributed significantly to the field of engineering with his innovative inventions. With a total of two patents to his name, he specializes in devices that enhance the measurement and pumping of materials, particularly within the rubber industry.

Latest Patents

Frédéric's latest patents include the "Orthogonal Rheometer" and the "Gear Pump with Prestressed Gear Teeth." The Orthogonal Rheometer is a sophisticated device designed to measure the rheological properties of viscoelastic materials. It comprises an upper rotating plate and a lower rotating plate that press against the sample material from opposite sides. The arrangement of the plates, with their parallel axes of rotation offset by a distance, allows for precise measurements without angular displacement between the plates.

The Gear Pump with Prestressed Gear Teeth, on the other hand, is engineered particularly for pumping materials like rubber mixes. This innovative pump features a central gear wheel and two peripheral gear wheels that work in tandem to move material from an inlet to an outlet efficiently. A unique prestressing device ensures that the meshing teeth maintain a tight seal, preventing any leakage of material during operation.
