Latest Patents
Among his latest patents is the "Dynamic consolidation of powders using a pulsed energy source." This invention involves a gas-operated part forming die apparatus that utilizes compact high tonnage presses. These presses are operated by high-pressure gas generated within chambers, which control high-pressure pistons and dies for compressing particulate material into dense formed parts. The combustion chambers are filled with pressurized mixtures of combustible gases and diluents, featuring elongated chambers with insulating walls and spaced electrodes. The invention also includes mechanisms for igniting combustible gases or creating arcs between electrodes, producing rapidly expanding high-pressure gases that drive pistons and movable dies.
Another significant patent is the "Switch contact device for interrupting high current, high voltage, AC and DC circuits." This high voltage switch contact structure is capable of interrupting high voltage, high current AC and DC circuits. The design confines the arc created when contacts open to a thin area between two insulating surfaces in intimate contact. This innovative approach forces the arc into a thin sheet shape, which loses heat energy more rapidly than a circular arc column. Consequently, this invention can rapidly interrupt both AC and DC circuits without relying on current zero crossings.
