Title: The Innovative Contributions of Rodney J Close
Introduction
Rodney J Close is a notable inventor based in Bristol, GB. He has made significant contributions to the field of metal casting, holding a total of 2 patents. His work focuses on improving the efficiency and effectiveness of casting processes, which has implications for various industries.
Latest Patents
Rodney J Close's latest patents include a method and mould for casting metal articles. This innovative method allows for moulding multiple castings, where each mould is fed from a source of molten metal through a thin slit ranging from 1.25 mm to 0.25 mm in width. The design enables easy removal of cast articles from the runner and riser system after casting, eliminating the need for machining operations. This efficiency allows casting moulds to be packed closer together, resulting in more castings produced from each mould assembly. Additionally, the thin slit serves as a filter, enhancing the overall quality of the castings.
Another patent by Close is a mould assembly for casting metal articles, which shares similar features to his previous invention. The cylindrical mould assembly consists of multiple wedge-shaped mould segments with mould cavities in abutting faces. The central runner passage is formed when the mould segments are assembled, allowing metal to flow into the mould cavities through narrow slits. After casting, the narrow flashing formed in the slits can be easily broken to remove the cast articles from the metal formed in the central runner passage.
