20080242893 | Process for Preparing Optically Active Diphosphanes - The present invention relates to a process for preparing optically active bisphosphinylalkanes from the correspondingly substituted, racemic 1,2-diols. The optically active bisphosphinylalkanes which can be obtained in this way are suitable as ligands for preparing chiral transition metal catalysts. | 10-02-2008 |
20090299089 | METHOD FOR PRODUCING OPTICALLY ACTIVE 3-AMINOCARBOXYLIC ACID ESTERS - The invention relates to a method for producing optically active 3-aminocarboxylic acid ester compounds. According to said method, an enantiomer mixture of a mono-N-acylated 3-aminocarboxylic acid ester, which mixture was previously enriched in an enantiomer, is subjected to deacylation and then to a further enantiomer enrichment by crystallization by adding an acidic salt-forming substance. | 12-03-2009 |
20100317866 | IMIDAZOLE GROUP-CONTAINING PHOSPHORUS COMPOUNDS - The present invention relates to phosphorus compounds containing imidazole groups, to optically active ligands prepared using them, to transition metal complexes which comprise such ligands, and to catalysts which comprise such transition metal complexes. The present invention further relates to the particular processes for preparing the phosphorus compounds, the optically active ligands, the transition metal complexes and the catalysts, and also to the use of the catalysts for organic transformation reactions. | 12-16-2010 |

20160114433 | METHOD OF WELDING IN DEEP JOINTS - The present relates to a method of welding in deep joints in narrow-gap geometry. The two metallic components are arranged next to each other such that there is nearly a zero gap between the two components. The step of joining two metallic components is performed in two stages, the first stage being a root weld and the second stage being a fill up weld. The root weld is completed at the joining of the two discs starting from a middle portion to a point up to which there is still a zero gap between the two discs. From the point there exists a non-zero gap between the two discs up to an outer portion. The filler gap is filled by fill up welding. During fill up welding, a filler wire is melted along with the two discs by using the first source of energy, and to fill the filler gap along with molten material of the two discs. | 04-28-2016 |

20130182989 | RADIAL CAGE FOR CYLINDRICAL ROLLER BODIES - A radial cage in which side rings have a material thickness of a starting material for the radial cage, straight side sections of each axial crossbar are implemented with a greater material thickness that increases their strength, and an axial center section of each axial crossbar is implemented with a smaller material thickness than the material thickness of the side rings, thus reducing centrifugal mass. | 07-18-2013 |
20130182990 | RADIAL CAGE FOR CYLINDRICAL ROLLER BODIES - A radial cage in which roll forming is carried out in such a manner that straight side sections of all axial crossbars continue to have at least approximately a material thickness of a starting material for the radial cage, while side rings of the radial cage and axial center sections of the axial crossbars are implemented by rolling down during roll forming to each have material thicknesses that are smaller than the material thickness of the straight side sections and that reduce their centrifugal mass. | 07-18-2013 |
