Latest Patents
Among his latest inventions is the "Accelerating Rate Calorimeter and Method of Operation." This instrument is designed to accurately determine the adiabatic thermal runaway characteristics of reactive chemicals. The operation involves measuring the adiabatic self-heat rate of exothermic chemical reactions to assess the acceleration of the reaction rate as a function of temperature. The basic instrument includes a sample vessel positioned inside a reaction chamber, with the surrounding environment being either air, an inert gas, or a vacuum. Separate heating mechanisms are provided for both the reaction chamber and the sample vessel. During the exothermic reaction, the temperatures are continuously monitored, and electronic controls adjust the temperature to maintain the desired adiabatic conditions. The data collected can be used to determine the adiabatic kinetics of the reaction.
Another significant patent is the "Diesel Engine with Dual Fuel Injection System and Method of Operation." This innovative engine is designed to operate on multiple fuel compositions, which may have the same or different auto-ignition temperatures. For instance, it can utilize diesel fuel oil as the primary fuel and a chlorinated hydrocarbon waste liquid as the secondary fuel. The waste liquid, having a higher auto-ignition temperature, is injected just before the diesel fuel, allowing the diesel to ignite first and serve as a spark for the secondary fuel.
