| 20090242292 | Method and system for operating an electric machine - In a method for operating an electric machine which is coupled to a drive shaft, the electric machine is connected to a high voltage direct-current power supply line (HDVC) by a switch and the rotational speed of the connected electric machine or of the drive shaft coupled with the electric machine is determined and the electric machine is disconnected from the high-voltage direct-current power supply line (HVDC) when the rotational speed of the electric machine or, respectively, the driveshaft is above a predetermined threshold. | 10-01-2009 |
| 20100060098 | METHOD FOR MANUFACTURING A WINDING FOR A STATOR OF AN ELECTRIC MACHINE - In a stator for an electric machine and a method for manufacturing a winding for the stator of such an electric machine L-shaped wire segments having a rectangular cross-section are inserted into slots arranged around the stator The long leg of the L-shaped wire segment is then inserted, into or through, a respective slot and the wire segment is then bent into an S-shape resulting in a second short leg while reducing a length of the long leg. The first short leg of each one of a majority of the wire segments is then electrically connected to the first short leg of another one of the wire segments and the second short leg of each one of a majority of the wire segments is electrically connected to the second short leg of yet another one of the wire segments. | 03-11-2010 |

| 20100152051 | NOVEL METHOD FOR THE IDENTIFICATION OF CLONES CONFERRING A DESIRED BIOLOGICAL PROPERTY FROM AN EXPRESSION LIBRARY - The present invention relates to a novel method for the identification and/or characterization of clones conferring a desired biological property from an expression library. The method of the invention comprises the step of analyzing for the expression of at least one (poly)peptide, such as a tag expressed as a fusion protein, together with a recombinant insert of a clone of said expression library, wherein the clones of said expression library are arranged in arrayed form. Said (poly)peptide may be fused N-terminally or C-terminally to said insert. The method of the invention further comprises the steps of contacting a ligand specifically interacting with a (poly)peptide expressed by the insert of a clone conferring said desired biological property with a first replica of said library of clones in arrayed form and analyzing said library of clones for the occurrence of an interaction, and/or carrying out a hybridization or an oligonucleotide fingerprint with a nucleic acid probe specific for the insert of a clone conferring said desired biological property with a second replica of said library of clones arranged in arrayed form and analyzing said library of clones for the occurrence of a specific hybridization. Finally, the method of the invention requires the identification of clones wherein an expression of the at least one (poly)peptide in step (a) and/or an interaction in step (b) and/or a hybridization or an oligonucleotide fingerprint in step (c) can be detected. The present invention also relates to a kit useful for carrying out the method of the invention. | 06-17-2010 |
