Title: Innovations by Larry D Spangler
Introduction
Larry D Spangler is a notable inventor based in Yorktown, Indiana, who has made significant contributions to the field of battery technology. He holds two patents that showcase his expertise in creating advanced intercell connectors for batteries. His work is characterized by innovative processes that enhance the efficiency and reliability of battery manufacturing.
Latest Patents
Spangler's latest patents focus on an apparatus for making intercell connectors through an improved extrusion-fusion process. This process involves casting plate strap lugs from a hypoeutectic lead-antimony alloy, which contains at least 2 percent by weight of antimony. The lugs are initially extruded into contact through an aperture in a battery intercell partition, with the contact area being between 15 and 75 percent of the aperture area. The process includes gradually heating the lug extrusions through various stages, including softening and melting phases. The application of force by rapid-response, declining-force welding electrodes allows the softened extrusions to reshape before melting, ensuring a dense, void-free weld. The resulting weld features an antimony-rich ring adjacent to the aperture wall, which is crucial for evaluating weld quality and monitoring manufacturing stability.
