Title: David Leon Watson: Innovator in Material Compaction
Introduction
David Leon Watson is a notable inventor based in Riceville, TN (US). He has made significant contributions to the field of material compaction, particularly in the context of electrochemical cells. With a total of 2 patents to his name, Watson's work showcases his innovative approach to solving complex engineering challenges.
Latest Patents
Watson's latest patents focus on a method of compacting material, specifically cathode material for electrochemical cells. This method involves inserting a mixture into a die cavity, where it is compacted into a disk shape. The process utilizes a first plunger that presses down on the material and a second plunger that presses upwardly. To prevent flashing of material during the ejection of the disk from the die, Watson has designed a polymeric sleeve that fits around the outer surface of the first plunger. This sleeve flexes to bulge outwardly, ensuring it does not enter the die cavity during compaction. It returns to its original position during the ejection process, preventing any material from flashing. Alternatively, a polymeric seal ring can be used around the first plunger, which also helps in preventing flashing during ejection.
