Title: Wilhelm Polhede: Innovator in Vacuum Technology
Introduction
Wilhelm Polhede is a notable inventor based in Bruchkobel, Germany. He has made significant contributions to the field of vacuum technology, holding a total of three patents. His work focuses on improving the efficiency and safety of vacuum furnaces.
Latest Patents
One of his latest patents is an apparatus for detecting gaseous discharge in vacuum furnaces. This invention features an electrically heated vacuum furnace equipped with special lead-through devices for transmitting current to the heating elements. To recognize gas discharges that may occur between a lead-through and a tank wall, the insulation of the lead-through is surrounded by an auxiliary electrode. Alternatively, a thermocouple can be used instead of an auxiliary electrode. A signal derived from the auxiliary electrode can be utilized to shut off the furnace power, thereby preventing potential damage. Another significant patent involves the heat treatment of materials. This installation is designed for vacuum heat treatment and subsequent hot isostatic redensification of materials. It comprises a work space inside a container, a heating unit, work-space insulation, and an outer chamber with both vacuum and pressure-gas connections. Notably, insulation is also provided at the interior of the chamber wall, which is water-cooled.
