Title: The Innovative Contributions of William A. Pfeiler
Introduction
William A. Pfeiler is a notable inventor based in Norris, TN (US). He has made significant contributions to the field of high-temperature applications, particularly through his innovative designs in crucible technology. With a total of 3 patents to his name, Pfeiler's work has had a lasting impact on melt-casting operations.
Latest Patents
One of Pfeiler's latest patents is for a non-graphite crucible designed for high-temperature applications. This multi-piece crucible features a tubular side wall member with a lip on the inside surface and a bottom member that forms a container for holding a melt during high-temperature melt-casting operations. The innovative design prevents cracking and leakage during the melt-casting process. The lip of the tubular member supports the bottom member, while the contacting surfaces are sealed with a ceramic material to ensure no leakage occurs. The crucible is constructed from materials that are chemically inert to the melt and maintain structural integrity at high temperatures. An embodiment of this design includes a vertical slot filled with ceramic sealing material, allowing for expansion without cracking during operations.
