Title: Innovations of David R Masters
Introduction
David R Masters is an accomplished inventor based in Knoxville, TN, with a notable portfolio of six patents. His work primarily focuses on advancements in materials and construction techniques, showcasing his innovative spirit and technical expertise.
Latest Patents
Among his latest patents is a unique foam and foam/cement mixture. This invention involves a foam composed of microscopic bubbles of surfactant, which are mixed with a water/cement mixture that has a water to cement ratio of less than 0.33. The small bubbles create a ball bearing effect on the smaller cement and sand particles, enhancing the plasticity or flowability of the mixture while reducing its water requirements. The foamed cement mixture is then laid to form a desired concrete structure, with the bubbles disintegrating to leave uniformly dispersed voids throughout the concrete. Another significant patent is the foam producing apparatus and method. This apparatus features a first mixing chamber with an inner subchamber connected to a gas supply at a first pressure and an outer subchamber connected to a foamable liquid supply at a higher second pressure. The foamable liquid is atomized to form droplets carried by gas to an outlet, where a second mixing chamber further agitates the droplets to produce the desired foam.
