| 20080269443 | Methods of oligomerizing olefins - The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene. | 10-30-2008 |
| 20080293899 | Methods For Oligomerizing Olefins - The present invention provides a method of producing oligomers of olefins, comprising reacting olefins with a catalyst under oligomerization conditions. The catalyst can be the product of the combination of a chromium compound and a pyridyl amine or a heteroaryl-amine compound. In particular embodiments, the catalyst compound can be used to trimerize or tetramerize ethylene to 1-hexene, 1-octene, or mixtures of 1-hexene and 1-octene. | 11-27-2008 |
| 20090131619 | METHODS OF USING HETEROCYCLE-AMINE LIGANDS, COMPOSITIONS, COMPLEXES, AND CATALYSTS - Ligands, compositions, and metal-ligand complexes that incorporate heterocycle-amine compounds are disclosed that are useful in the catalysis of transformations suchas the polymerization of monomers into polymers. The catalyst have high performance characteristics, including higher comonomer incorporation into ethylene/olefin copolymers, where such olefins are for example, 1-octene, propylene or styrene. The catalysts also polymerize propylene to form isotactic polypropylene. | 05-21-2009 |

| 20100213930 | Integrated micro actuator and lVDT for high precision position measurements - A single housing with a non-ferromagnetic piezo-driven flexure has primary and secondary coil forms of different diameters, one coaxially inside the other, integrated in the flexure. The cylinders defining the planes of the primary and secondaries do not spatially overlap. The secondary coil forms may be wound in opposite directions and wired to provide a transformer device. Movement of the primary relative to the secondaries in the direction of the central axis of the coils can be differentially detected with high precision. | 08-26-2010 |
