**Title: Insights into the Innovations of Richard A. Cairncross**
Introduction
Richard A. Cairncross, an accomplished inventor located in Saint Paul, MN, has made significant contributions to the field of mechanical design and polymer processing. With a patented invention under his name, Cairncross showcases his expertise and innovative spirit, particularly in the application of drying technology for thick polymer-solvent layers.
Latest Patents
Cairncross holds a patent for a "Method and apparatus for a mechanical dryer for drying thick polymer." This invention introduces a dryer equipped with zone temperature controls specifically designed to dry thick polymer-solvent layers on a substrate. The innovative dryer is constructed with multiple heating elements within an air duct, allowing cool air to be heated incrementally as it passes through these elements. This method ensures that the polymer-solvent solution gradually warms as it travels through the drying apparatus. His design emphasizes achieving a zone residence time of under 10 seconds, with a heating rate of 10°F per second or lower. The most efficient iteration aims for a zone residence time of less than 5 seconds and a heating rate of under 5°F per second, particularly crucial during the final drying stages when solvent content drops below 20%.
