20080284414 | Hysteresis Brake, Especially for an Electric Camshaft Adjuster - A hysteresis brake is provided, such as for an electric camshaft adjuster, has with an excitation coil, a stator with an inner and outer stator part, and a moveable rotor with a hysteresis band which is movable between the inner and outer stator part. The excitation coil, which produces a main magnetic flux for a magnetic adjuster is arranged between the inner and outer stator part. A sensor enables the rotor and/or the hysteresis band to receive a secondary magnetic flux caused by the main magnetic flux, or enables the excitation coil to receive the main flux. An evaluation and control unit evaluates the magnetic flux received and determines angle and/or rotational speed information from detected changes of the magnetic flux. | 11-20-2008 |
20110088643 | Valve train device - In a valve drive train device, in particular for a valve drive of an internal combustion engine, with a switching unit comprising an actuator with a solenoid unit and with a control unit for monitoring switching operations of the switching unit provided for switching an axially displaceable cam element by means of a switch gate, the control unit for monitoring the switching unit is taking into account at least one characteristic value of a voltage integral over a voltage which is induced in a coil of the switching unit during the switching operation and is adjusting the value with respect to a characteristic limit value stored in the control unit. | 04-21-2011 |
20110159339 | BATTERY WITH A HEAT CONDUCTING PLATE - The invention relates to a battery with a heat conducting plate for controlling the temperature of the battery. The battery comprises a plurality of single cells connected in parallel and/or in series to each other, the cells being connected to the heat conducting plate in a heat conducting manner. In the heat conducting plate, a channel structure for a heat conducting medium is provided. In the region of the poles of the single cells, the heat conducting plate comprises bores through which the poles of the single cells extend. | 06-30-2011 |

20120330018 | PROCESS FOR PREPARING PHARMACEUTICAL COMPOUNDS AND INTERMEDIATE COMPOUNDS - The object of the present invention is a process for preparing the 2-acetoxy-5-(2-fluor-α-cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-tieno[3,2-c]pyridine (prasugrel) of the formula (I). The process starts form crystalline 5-trityl-4,5,6,7-tetrahydro-tieno[3,2-c]pyridine of the formula (VI). Further objects of the present invention are two novel crystalline forms of 5-trityl-4,5,6,7-tetrahydro-tieno[3,2-c]pyridine of the formula (VI) and the use thereof for preparing the compound of the formula (V) and process preparing thereof. | 12-27-2012 |
20130030183 | PROCESS FOR PREPARING A PHARMACEUTICAL COMPOUND - The object of the present invention is a one-pot process for preparing the 2-acetoxy-5-(2-fluoro-α-cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-tieno[3,2-c]-pyridine (prasugrel) of the formula (I) by reacting the 5,6,7,7a-tetrahydro-4H-tieno[3,2-c]-pyridine-2-on of the formula (II) with 2-bromo-1-cyclopropyl-2-(2-fluorophenyl)-etanone of the formula (III) or with 2-chloro-1-cyclopropyl-2-(2-fluorphenyl)-etanone of the formula (IIIa) and acetylating of the formed compound of the formula (IV), wherein the reaction is carried out in the presence of an organic base with an acetylation agent without isolating the compound of the formula (IV). The coupling and acetylation are carried out in the presence of the same organic base such as triethylamine, N,N-diisopropyl-ethylamine or pyridine. At the end of the process the prasugrel of the formula (I) is purified by recrystallization from an organic solvent or a mixture of solvents. | 01-31-2013 |
