Latest Patents

Marshall Tulin holds a patent for an "Apparatus for Measuring the Representative Parameters of Rheological Fluids." This revolutionary device consists of two similar cylinder-piston assemblies that conclude at identical flow orifices. The conjointly pushed pistons, operated by a motor at an adjustable speed, allow for precise measurements of fluid parameters. The setup includes a differential manometer located between the cylinders just before the orifices. One cylinder is filled with the fluid under study, while the other contains a Newtonian comparison fluid. By controlling the flow rates, Tulin's apparatus measures strain rates and calculates the elongation stress of the viscoelastic fluid. This invention is pivotal for the rheological evaluation of dilute solutions of macromolecular compositions.
