Title: Innovations by Brian D. Cox

Introduction

Brian D. Cox is an accomplished inventor based in San Luis Obispo, California. He has made significant contributions to the field of material testing, particularly with his innovative flow-no-flow tester. With a total of two patents to his name, Cox has demonstrated a commitment to advancing technology in his area of expertise.

Latest Patents

Cox's latest patents include the flow-no-flow tester, which is designed to measure the physical properties of particulate materials. This instrument allows for the determination of flow characteristics, featuring an improved compaction assembly with a retractable sleeve and a test cell with cylindrical walls. The design includes a failure outlet smaller than the diameter of the failure piston and a removable false bottom for easy access to the compacted material. This tester is capable of determining the confined yield strength, bulk density, and permeability of materials.

Another version of the flow-no-flow tester offers significant improvements over its predecessor. It eliminates the need to invert the test cell after compaction, reducing the risk of sample failure before testing. Additionally, it measures the compaction load more accurately by assessing the force exerted by the sample against an upper piston, while a lower piston applies compressive force. This design minimizes particle binding and enhances the accuracy of the results, allowing for the measurement of viscous properties and pseudo strength of fine powders.
