| 20100081680 | N-SULFONAMIDO POLYCYCLIC PYRAZOLYL COMPOUNDS - The current invention provides compounds having a structure according to Formulae 1, 2, 3, and 4: | 04-01-2010 |
| 20110034691 | Process for the Production of Fused, Tricyclic Sulfonamides - The present invention provides methods, i.e., scalable or large-scale processes for the production of fused, tricyclic sulfonamido analogs, such as substituted or unsubstituted 5-(aryl-sulfonyl)-4,5-dihydro-1H-pyrazolo[4,3-c]quinolines and 5-(heteroaryl-sulfonyl)-4,5-dihydro-1H-pyrazolo[4,3-c]quinolines. Exemplary methods of the invention include an intra-molecular cyclization step, in which a carbon-nitrogen bond is formed, and which employs a copper-based catalyst that contains at least one organic ligand, such as DMEDA. The invention further provides compounds, which are useful as intermediates in the methods of the invention. | 02-10-2011 |

| 20110073590 | Inductor and use of such an inductor - An inductor is provided for the simultaneous inductive heating of two tracks or ways which are formed next to one another on a metallic workpiece, having a first segment which is associated with the first track or way and a second segment which is associated with the second track or way, and having two supply arms via which the segments can be connected to a power supply. To enable two tracks or ways to be heated simultaneously to the hardening temperature without heating the material portion situated between the tracks or ways the segments of the inductor and the supply arms are connected together in an inductor in such a way that the fields travelling at right angles to the longitudinal extent of the tracks or ways neutralize each other in the region of the material portion which separates the tracks or ways from one another. | 03-31-2011 |
| 20110084062 | Device for inductive heating and use of such a device - A device is provided having at least one inductor for the inductive heating of a zone formed in a metallic workpiece, which zone is adjoined by a narrow material portion which is to be protected against heating up. To enable two tracks or ways arranged next to one another to be heated simultaneously without the portion of material situated between the tracks or ways being heated throughout to this temperature in the process, the invention provides a cooling means which delivers a cooling fluid onto that material portion of the workpiece which is to be protected against heating up. The device is particularly suitable for the simultaneous inductive heating of two tracks or ways which are formed on a workpiece next to one another and at a distance from one another and which are separated by a narrow material portion. | 04-14-2011 |
| 20110089164 | Device for hardening a cylindrical section of a workpiece and use of such a device - The invention relates to a device for hardening the surface F of a cylindrical workpiece section Z which has an undercut H | 04-21-2011 |
