Osmotically-Driven Pump for Use in High Pressure Applications

Current designs of osmotic pumps that are used to deliver small amounts of fluids have limited control over the flow rate. The technology presented here is a high pressure osmotic dispense pump having a substantially continuous delivery rate and extended delivery times. The operation of the pump i...

Electrochemical Method of Reducing Scale on or in Metal Pipes

Nearly all industries rely on hard water transport through pipelines for process water or heat exchange. In most cases the dissolved salts in the water deposit gradually on the pipe walls, restricting fluid flow and increasing pumping cost. Sometimes these deposits become so large that the pipelines...
