| 20090117358 | Extruded Polymer Foams Containing Brominated Fatty Acid-Based Flame Retardant Additives - Extruded polymer foams are prepared using brominated fatty acids, an ester, amide or ester-amide of a brominated fatty acid, a glyceride of one or more brominated fatty acids, or a polymerized brominated fatty acid as an FR additive. The brominated FR additives unexpectedly are stable at the extrusion temperatures, and provide excellent flame retardancy to the foams. | 05-07-2009 |

| 20090038961 | Process and System for Treating Radioactive Waste Water to Prevent Overloading Demineralizer Systems - A process and system for treating waste water containing contaminants to prevent excessive accumulation on demineralizer media of a driver contaminate capable of such accumulation before another contaminant can reach a predetermined level of accumulation. The waste water is treated upstream of the demineralizer media with removal means for specifically removing the driver contaminant while leaving the other contaminant for subsequent removal by the demineralizer media. The amount of accumulation on the demineralizer media of the other contaminant is monitored, and the supplying of treated waste water to the demineralizer media is terminated when its accumulation reaches the predetermined level. | 02-12-2009 |

| 20100173811 | ADDITIVES AND LUBRICATING OIL COMPOSITIONS CONTAINING SAME - Para-alkylated substituted diphenylamines are made by catalytically alkylating diphenylamine with a branched-chain alkene, such as propene, oligomer mixture in which the oligomer present in the greatest percentage has 15-24 carbon atoms. The alkylated diphenylamines are useful crankcase lubricant additives such as for reducing piston deposits and engine sludge. | 07-08-2010 |
