Latest Patents

Cracchiolo is credited with 1 patent: “Method and Apparatus for the Production of Purified Liquids and Vapors.” The invention describes placing a liquid in a sealed vessel, cooling it below its freezing point until it substantially solidifies, and evacuating the vessel’s gaseous atmosphere with a vacuum. The vessel is then heated above the liquid’s melting point, allowing the material to return to liquid form or sublimate into vapor. The process is designed to produce liquids and vapors that are free of, or substantially free of, dissolved or trapped gases.
