Title: Paul T Gray: Innovator in Foam Technology
Introduction
Paul T Gray is a notable inventor based in Laguna Hills, CA. He has made significant contributions to the field of foam technology, holding 2 patents that showcase his innovative approach to materials science. His work focuses on enhancing the properties of cement mixtures through the incorporation of foam.
Latest Patents
One of Gray's latest patents is for a 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, which increases the plasticity or flowability of the mixture. This innovation reduces the water requirements for the mixture, allowing for the creation of concrete structures with uniformly dispersed voids once the bubbles disintegrate.
Another significant patent by Gray is for a 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 supply of foamable liquid at a higher second pressure. The design includes orifices that connect the outer subchamber to the inner subchamber, allowing the foamable liquid to be atomized and carried by gas to an outlet. A second mixing chamber is then used to agitate the droplets, producing the desired foam.
