Latest Patents
One of his latest patents is a water conditioning system designed for bacterial control in evaporative cooling systems. This system reduces operating costs and microbial contamination by introducing positively charged copper-silver ions into the water used as a working fluid. Additionally, some of the recirculating water is passed through a magnetic conditioner to enhance its conductivity. By concentrating the total dissolved solids (TDS) in a portion of the water to be expelled, the remaining system water, along with new make-up water, contains significantly lower TDS levels. This innovation reduces health risks, maintenance costs, corrosion, and scaling, while extending the service life of replaceable filter elements and system machinery. Another significant patent involves a multi-piece sealing assembly for use in a torque converter of a motor vehicle. This assembly includes an inner ring, an outer ring, and an elastomer compensation layer positioned between them. The inner and outer rings are crafted from a composite wear material, and the design features interlocking tabs that enhance the assembly's functionality.
