Title: Innovations by Nicholas G Walker
Introduction
Nicholas G Walker is an accomplished inventor based in West Chester, PA (US). He has made significant contributions to the field of liquid treatment technologies, holding a total of 3 patents. His work focuses on improving the efficiency of impellers used in various liquid systems.
Latest Patents
One of his latest patents is a "Method for treating a liquid with a gas using an impeller." This invention features an improved impeller head designed for treating molten metals and other liquid systems with gas. The multiple-vaned impeller head is mounted on a hollow impeller shaft, allowing it to rotate within the liquid. The edges of the impeller vanes are extended by an axial groove that intercepts the hub and the vanes of the impeller head. This extension of the trailing edge of the vanes creates greater turbulence in the liquid, enhancing the impeller's efficiency. Additionally, the impeller vanes may have canted leading surfaces that generate an upward axial flow of liquid, which helps to discourage the formation of a surface vortex. Multiple impellers can also be mounted on a shaft in the vessel, with gas introduced remotely.
Another notable patent is the "Impeller for treating molten metals." Similar to his previous invention, this impeller head is designed for treating molten metals and other liquid systems with gas. The design features a multiple-vaned impeller head that is also mounted on a hollow impeller shaft for rotation within the liquid. The improvements in this design focus on increasing efficiency and reducing the likelihood of surface vortex formation.
