Title: The Innovative Contributions of Frank R. Trowbridge
Introduction: Frank R. Trowbridge is an accomplished inventor based in Macon, GA, recognized for his significant contributions to the field of materials science. With a total of three patents to his name, Trowbridge has dedicated his career to advancing processes related to the production and mixing of materials, particularly in the realm of calcium carbonate.
Latest Patents: Among his latest innovations, Trowbridge developed a patent for a "Method of producing ultrafine ground calcium carbonate." This process involves slurrying dry feed stone to create a 15 to 60% by weight solids slurry, which is then dispersed with an organic dispersant. The dispersed slurry is processed in an attrition mill to achieve particle sizes less than 2 microns. Additionally, Trowbridge's method incorporates the use of ozone to enhance product brightness and returns the slurry to a non-dispersed state. His other notable patent is for a "Dispersing apparatus with grooved impeller," designed to efficiently mix solids within liquids. This impeller, made of ultra-high molecular weight polyethylene, features radially extending grooves that enhance its longevity and mixing efficacy.
Career Highlights: Throughout his career, Trowbridge has made significant strides in materials processing. His tenure at J.M. Huber Corporation and Morehouse Industries, Inc. provided him with invaluable experience that influenced his innovative approaches to production and materials science.
Collaborations: Collaboration has played a vital role in Trowbridge's success. He has worked alongside respected colleagues such as Charles R. Price and Walter B. Bryan, which has enriched his invention journey and fostered a creative environment for innovation.
Conclusion: Frank R. Trowbridge stands out as a dedicated inventor whose work continues to impact the materials science sector. His patents demonstrate a commitment to improving production techniques and material quality, ensuring that his contributions will be felt for years to come.
