Latest Patents

One of his latest patents is a method of making structural members using waste and recycled plastics. This composite formulation consists of agglomerated industrial and residential sewer sludge combined with recycled high-density polyethylene (HDPE) and/or polypropylene (PP) materials. The recycled plastic materials serve as a binder for the pozzolan industrial and residential sewer sludge. The composite formulation can be produced through a batching process, where the sieved dried sewer sludge and appropriately cut recycled plastic pieces are fed into a large plastic extruder, heated, and extruded into specific structures. Additionally, the formulation can be compounded using a compression mold, where sieved dry sewer sludge is added to heated chopped recycled plastics, mixed, and directed into a compression mold to create a structural member of a predetermined shape.

Another notable patent is the heated wiper blade using conductive elastomer. This innovative wiper blade features a conductive elastomer body with a pair of electrodes along each side. The elastomer has a resistivity in the range of 20-128 ohm-cm and a hardness of Shore A 64-70. It comprises a rubber compound that includes carbon black in the range of 37-60 parts per hundred rubber (phr), a small amount of graphite in the range of 13 to 20 phr, and a low concentration of plasticizer oil in the range of 20-40 phr.
