Title: The Innovative Contributions of Benjamin T. Chen

Introduction

Benjamin T. Chen is a notable inventor based in Penfield, NY (US). He has made significant contributions to the field of photographic technology, holding a total of 15 patents. His work primarily focuses on the development of advanced mixing apparatuses for preparing silver halide grains, which are essential in photographic processes.

Latest Patents

One of his latest patents is titled "Scalable impeller apparatus for preparing silver halide grains." This invention features a mixer designed for the preparation of silver halide grains used in photography. The apparatus includes upper and lower impellers housed within a draft tube. The bottom impeller is equipped with flat blades for micromixing silver and halide reactants, while the upper impeller has pitched blades for macromixing the bulk fluid. The design ensures that the two impellers operate independently, allowing for effective micromixing and macromixing. Additionally, a flow disrupter is incorporated to prevent vortexing during the mixing process, and baffles may be included to further discourage vortexing.
