Patent application number	Description	Published
20080251427	Flotation Separation Device and Method - A flotation separation system is provided for partitioning a slurry that includes a hydrophobic species which can adhere to gas bubbles formed in the slurry. The flotation separation system comprises a flotation separation cell that includes a sparger unit and a separation tank. The sparger unit has a slurry inlet for receiving slurry and a gas inlet to receive gas with at least enough pressure to allow bubbles to form in the slurry within the sparger unit. The sparger unit includes a sparging mechanism constructed to disperse gas bubbles within the slurry. The sparging mechanism sparges the gas bubbles to form a bubble dispersion so as to cause adhesion of the hydrophobic species to the gas bubbles substantially within the sparger unit while causing a pressure drop of about 10 psig or less across the sparging mechanism. The sparger unit includes a slurry outlet to discharge the slurry and the bubble dispersion into the separation tank.	10-16-2008

20090242479	AROMATIC HALOSULFONYL ISOCYANATE COMPOSITIONS - The present invention provides a polymer composition comprising structural units derived from an aromatic halosulfonyl isocyanate having structure I	10-01-2009
20090242831	AROMATIC HALOSULFONYL ISOCYANATE COMPOSITIONS - The present invention provides a monomer composition comprising an aromatic halosulfonyl isocyanate having structure I	10-01-2009
20100216917	ALIPHATIC POLYCARBONATES FOR USE IN THERMOSETTING POWDER COATINGS - A thermosetting polymer material capable of being used in powder coatings. The thermosetting polymer material includes at least one hydroxyl functional aliphatic polycarbonates that is formulated and crosslinked with isocyanates to yield a thermoset organic coating material. These materials provide improved weatherability as compared to prior art powder coating materials while also being less expensive than prior art materials utilizing fluorinated polymers.	08-26-2010
