Title: Innovations by Inventor Charlotte Frederick
Introduction
Charlotte Frederick is an accomplished inventor based in Tempe, AZ (US). She has made significant contributions to the field of cleaning technologies, holding a total of 3 patents. Her innovative methods focus on improving the efficiency and environmental impact of cleaning processes.
Latest Patents
One of her latest patents is titled "Aqueous cleaning of liquid residue by etching." This invention presents a method for cleaning objects in an open aqueous cleaning system. The process involves introducing water into an open cleaning vessel, along with a reactant chemical to form an aqueous solution. The cleaning occurs through bubble formation, which vaporizes the chemical to react with the oxidizer on the exposed surface. This method effectively removes contaminants without causing dissolution or emulsion, thus conserving chemistry, water, and energy while reducing pollution.
Another notable patent is the "Method for removing particles and non-volatile residue from an object." This invention outlines a cleaning method within a controlled environment processing chamber. The process begins by applying negative gauge pressure to the chamber, followed by the introduction of solvents, water, or gases to eliminate soluble contaminants. A secondary cleaning step utilizes high-velocity vapor to remove any remaining insoluble materials. The final steps involve recovering residual liquids or vapors and returning the chamber to atmospheric pressure for the removal of the cleaned object.
