| 20110034657 | Reactor Systems and Processes for Using the Same - A process for the polymerization of olefin's, including: introducing an olefin and a polymerization catalyst into a polymerization reactor to form a polyolefin, the polymerization reactor including: a fluidized bed region having a top and a bottom; and a motive bed region; wherein a first end of the motive bed region is fluidly connected to the top of the fluidized bed region; and wherein a second end of the motive bed region is fluidly connected to the bottom of the fluidized bed region; and wherein a diameter of the fluidized bed region is greater than a diameter of the motive bed region; circulating at least a portion of the olefin, the catalyst, and the polyolefin through the fluidized bed region and the motive bed region; maintaining a dense-phase fluidized bed within the fluidized bed region; recovering polyolefin from the fluidized bed region, is provided. A reactor system directed to the process is also provided. | 02-10-2011 |

| 20110059454 | FLUORESCENCE ENERGY TRANSFER BY COMPETITIVE HYBRIDIZATION - A method is provided for detecting the presence of nucleotides or monitoring nucleotide amplification. It utilizes fluorescence energy transfer by competitive hybridization. Competitive hybridization is achieved by using unequal length complementary probes which have a fluorophore on one probe and a quencher on the other. The fluorophore and quencher are juxtaposed in a manner wherein the proximity of the quencher to the fluorophore produces quenching of the fluorescence of the fluorophore. | 03-10-2011 |

| 20100314109 | GRAVEL PACK COMPLETIONS IN LATERAL WELLBORES OF OIL AND GAS WELLS - A technique enables an efficient, dependable approach to gravel packing lateral wellbores. The technique employs alternate path gravel placement technology which includes alternate path equipment deployed along a gravel pack screen positioned in an open hole lateral wellbore disposed above a lower lateral wellbore. A crossover system is positioned in the lateral wellbore, and the alternate path is provided by connecting a shunt tube or other appropriate alternate path equipment to the crossover system. A flow of gravel slurry is directed along an exterior of the gravel pack screen through the alternate path equipment to enable uniform distribution of the gravel pack along the gravel pack screen. | 12-16-2010 |

| 20100324340 | SHORT CHAIN POLYETHER POLYOLS PREPARED FROM ULTRA-LOW WATER-CONTENT STARTERS VIA DMC CATALYSIS - The present invention provides a process for the polyoxyalkylation of a starter involving establishing oxyalkylation conditions in an oxyalkylation reactor in the presence of a double metal cyanide (DMC) catalyst, continuously introducing into the reactor at least one alkylene oxide and an acidified, ultra-low water content starter, in which the starter contains greater than about 100 ppm and less than or equal to about 500 ppm water, based on the weight of the starter, and recovering an oxyalkylated low molecular weight starter polyether product. The inventive process allows the production of short chain polyether polyols which have hydroxyl numbers of from greater than 250 up to about 500, from hygroscopic initiators, such as glycerin, without DMC catalyst deactivation. | 12-23-2010 |
