Introduction

John W. Alden, Jr. is an accomplished inventor based in Chattanooga, TN, recognized for his significant contributions to the field of engineering, particularly in the design and functionality of nuclear steam generators. He holds two patents that showcase his innovative approach to solving complex engineering challenges.

Latest Patents

One of Alden's most notable patents involves the removal of suspended sludge from a nuclear steam generator. This invention features a shell and tube heat exchanger designed with a vertical dam surrounding one of the steam-water separators. This dam creates a low flow velocity area where solids can settle out, significantly enhancing the efficiency of sludge removal. The design ensures that the area encircled by the dam is seven times greater than the average area per separator throughout the separating deck, thus facilitating optimal settling of solids. Additionally, an orifice positioned at the inlet further reduces the flow velocity, allowing for effective removal of settled solids through a blowdown pipe.

The second patent addresses the primary manway closure’s redundant restraint, which includes a vessel with an opening mechanism and a cover. The design incorporates a flange that surrounds the opening, with a primary closing mechanism secured by a series of studs and nuts. This innovative solution enhances the structural integrity of the cover, ensuring safety and reliability in its operational capabilities. The use of cylindrical clamps and a retaining ring fortified with set screws adds an extra layer of security, ultimately providing a robust assembly for maintaining safety standards in engineering applications.
