Title: The Innovations of John P. MacMillan
Introduction
John P. MacMillan is an accomplished inventor hailing from Renfrew, CA. With a notable portfolio of two patents, he has made significant contributions to the field of non-explosive fine metallic powders and their applications in refractory mixtures.
Latest Patents
MacMillan's latest patents focus on innovative processes and formulations in the realm of materials science. His first patent, "Non-explosive fine metallic powder mixtures for making refractories," reveals a mixed powder containing finely divided metallic particles, which is intimately combined with inert refractory particles. This mixture ensures that the Minimum Explosible Concentration, as tested in a 20-L vessel with a chemical igniter, exceeds 100 gm/m³. The inert particles are incorporated in quantities ranging from 40% to 80% of the mixture, allowing the powder to be shipped without the usual safety precautions associated with finely divided metal powders.
His second patent, "Production of non-explosive fine metallic powders," outlines a process for creating a substantially non-explosive powder by grinding a mixture of metallic pieces and inert refractory materials. This method produces a premixture where the finely divided metallic and refractory particles are delicately combined, maintaining a Minimum Explosible Concentration greater than 100 gm/m³. Like the first, this patent also emphasizes shipping convenience, as the premixed powder can be contained in drums or impermeable bags.
