Title: The Innovations of Hans Wilhelm Wieking
Introduction
Hans Wilhelm Wieking is a notable inventor based in Goslar, Germany. He has made significant contributions to the field of metallurgy, particularly in the refining of cadmium. With a total of 2 patents to his name, Wieking's work showcases his expertise and innovative spirit.
Latest Patents
Wieking's latest patents include a method and apparatus for refining crude cadmium through vacuum distillation. This innovative method involves passing crude cadmium into a reflux condenser, where higher boiling point impurities are condensed alongside a portion of pure cadmium vapor. The condensate flows in counterflow with the crude cadmium vapor, allowing for efficient separation. The remaining pure cadmium vapor is subsequently condensed. The apparatus features an inverted U-shaped vacuum chamber, which includes an evaporator and a reflux condenser in one leg, and a further condenser in the other leg. A feed pipe for liquid crude cadmium enters the one leg adjacent to the evaporator, while a residue outlet pipe leaves the same leg. This design prevents any back-flow from the residue pipe to the feed pipe. An outlet pipe for the refined cadmium issues from the other leg of the vacuum chamber.
