Title: Paul Niessen: Innovator in Metal Processing Technologies
Introduction
Paul Niessen is a notable inventor based in Waterloo, Canada. He has made significant contributions to the field of metal processing, particularly in the development of methods and apparatuses for producing metal strips and improved gear pumps for molten metals. With a total of 2 patents, his work has had a considerable impact on the industry.
Latest Patents
One of Paul Niessen's latest patents is a method and apparatus for producing metal strips. This innovative process involves casting a strip on a chilled casting surface of a rotating drum from a pool of molten metal contained in a tundish. The tundish features a graphite lip insert that works in conjunction with the casting surface to form and maintain the pool of molten metal. This design includes a feed chamber, a return chamber, and a diverting chamber, which effectively reduces turbulence in the molten feed. The return chamber is equipped with a vertically adjustable weir that controls the surface level of the molten metal pool, enhancing the overall efficiency of the casting process. The method is particularly effective for producing expanded mesh battery grids with improved electrochemical properties, such as corrosion resistance.
Another significant patent by Niessen is an improved gear pump designed for pumping molten metals, including lead and lead alloys. This innovative pump incorporates sealing mechanisms to prevent the loss of metal flowing along the pump drive shaft. Additionally, a cooled annulus surrounds the pump drive shaft, solidifying molten metal to create an effective seal and bearing, thereby enhancing the pump's performance and reliability.
