Latest Patents
One of his notable inventions is the "Apparatus for inside-outside tube quenching." This innovative quenching arrangement is designed for long steel pipes, utilizing a tangential quench to cool the pipe's exterior and an axial flow nozzle for the interior. This dual cooling method ensures that both surfaces cool at approximately the same rate. The design includes a manifold with jet nozzles that can pivot apart, allowing for a four-bar linkage mechanism to efficiently transfer the pipe in and out of the quenching system. Additionally, a roller drive arrangement rotates the pipe while keeping it in a stationary position, minimizing bowing and enhancing cooling efficiency.
Another significant patent is the "Device for cleaning a filter used in conjunction with a galvanizing process." This device filters zinc powder from the airstream exhausted during galvanizing. It features an enclosed chamber where the airstream circulates for zinc removal. The chamber's bottom surface has multiple circular openings leading to vertically disposed bag-type filters. An arm connected to a vertical drive shaft moves a circular cover to seal the openings individually, allowing for effective cleaning of the filters.
