Title: Innovations by Ronald C Aufderheide
Introduction
Ronald C Aufderheide is a notable inventor based in Delaware, OH, with a remarkable portfolio of 11 patents. His work primarily focuses on advancements in metal casting technologies, showcasing his expertise and innovative spirit in the field.
Latest Patents
Among his latest inventions is the "Filtering check valve for metal casting." This innovative design features a sleeve that allows the flow of molten metal against gravity into a casting mold. The sleeve includes a body with a longitudinal axis that defines a flow conduit for the metal. A check valve is strategically positioned within the flow conduit, allowing limited axial movement between closed and open positions. In the absence of pressurized metal, the check valve remains closed. The design incorporates a spool with an internal flow conduit, capped at the top end, and flanges that facilitate the limited axial movement. When the valve is lifted into the open position, molten metal flows through the spool's flow conduit and a porous structure, promoting laminar flow and filtering out inclusions. Another significant patent is related to "Coated microspheres and their uses," which involves microspheres coated with a phenolic novolak resin. This invention outlines a process for preparing these microspheres and their application in creating foundry shapes, such as molds and cores, essential for casting metal parts.
