Title: Innovations by Judith G Stevens in Aluminum Processing
Introduction
Judith G Stevens is a notable inventor based in McMurray, PA (US). She has made significant contributions to the field of aluminum processing, particularly through her innovative patent that enhances the purification of molten aluminum.
Latest Patents
Judith holds a patent for the "Purification of molten aluminum using upper and lower impellers." This process and apparatus improve fluxing gas dispersion in treating molten aluminum by increasing the fluxing gas surface area. The method involves a molten body of aluminum and a gas dispersing unit that features at least two dispersers, both upper and lower, mounted on a shaft extending into the molten aluminum. The dispersing unit is rotated while a fluxing gas is added adjacent to the lower disperser. This setup allows the lower disperser to create finely divided bubbles, which are then re-dispersed by the upper disperser, effectively increasing the fluxing gas surface area in the molten body.
