Process for the distillation of mixtures containing salts with a melting point below 200 ° C at 1 bar (ionic liquids) contained, characterized in that - contains the cation of ionic liquid, a heterocyclic ring system with at least one nitrogen atom and all nitrogen atoms of the heterocyclic ring sys...

The present invention provides novel hydrolytically decomposable ionic copolymers. These ionic copolymers are made up of a cyclic ketene acetal A, an anionic or cationic methacrylic acid derivative B selected from 2-methyl-methacrylate, [2-(2-methyl-1-methylen-allyloxy)-ethane sulfonate, [2-(2-methy...

Removal of undesirable/toxic inorganic contaminants from waster water and drinking water is a major challenge owing to the stringent EPA regulations. Although, several methods have been proposed and shown to be effective for removal of these contaminants, large scale, economic removal will most lik...

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...

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...

This invention meets the needs of those expressing an interest in inexpensive sensor measuring tools for the measurement of water quality, clarity and environmental ground truth measurements in support of field experiments. The sensor can be launched using any of the three inch signal ejectors and w...

The present invention is a heated element sensor for detecting the flow rate of a fluid or other physical characteristics of a fluid. The invention teaches driving the thermo-resistive element along a profile having at least two states and measuring the power and temperature of the sensor at each st...
