| 20090221860 | TRANSPORT OF ETHYNE IN FORM OF A-ALKYNOLS AS ETHYNE PRECURSORS - The present invention relates to a new method for a safe transport of ethyne in form of α-alkynols as precursors for ethyne. The new method comprises three steps. In a first step the synthesis of the α-alkynol(s) is performed by reacting ethyne with (a) carbonyl compound(s). The second step comprises the transport of the resulting α-alkynol(s) in a safe manner, whereas the safety requirements for this transport are not as high as for ethyne because α-alkynol(s) are normally classified for transportation as hazardous class 3. In the third step the α-alkynol(s) can be cleaved and the ethyne and the carbonyl compound(s) can be obtained in the cleavage reaction and can be separated to yield pure products for further applications. | 09-03-2009 |

| 20080255746 | Method and Device for Influencing the Longitudinal Velocity of a Motor Vehicle - A method and device for influencing the longitudinal velocity of a motor vehicle, in which a setpoint minimum distance and/or a setpoint maximum velocity is presettable by the driver, the driver being able to influence the vehicle velocity via the accelerator pedal and/or brake pedal, and in which the distance from a vehicle traveling ahead is measured by a distance-measuring sensor and, if the setpoint minimum distance is undershot and/or the setpoint maximum velocity is exceeded by the vehicle velocity, the vehicle velocity is limited so that the setpoint minimum distance is not undershot and/or the setpoint maximum velocity is not exceeded. This function is provided, in particular, in connection with an adaptive distance and cruise control system, the driver being able to activate either the adaptive distance and cruise control system or the limiting function. | 10-16-2008 |
| 20100191436 | Device for longitudinally guiding a motor vehicle - A device is described for longitudinally guiding a motor vehicle, including a sensor system for locating preceding vehicles, a controller that regulates the speed of the vehicle to a setpoint speed, either in a following driving mode as a function of the distance from a preceding vehicle or in a free driving mode, an interface to a navigation system which provides information about the traveled route, and a limiting device for limiting the setpoint speed based on the provided information. The limiting device is designed for calculating a limiting value for the setpoint speed for each possible route when the travel route is recognized as being ambiguous and for selecting the greatest of these limiting values for limiting the setpoint speed. | 07-29-2010 |
| 20110180337 | Method and Device for Operating a Vehicle Having a Hybrid Drive - A method and a device for operating a vehicle having a hybrid drive are described, in which a first drive unit and a second drive unit contribute jointly or individually to the drive of the vehicle, the first drive unit driving the second drive unit in the manner of a generator for charging an energy storage device, the first drive unit and the second drive unit being separable by a drive train element transferring a torque of the first drive unit. In a method in which it is ensured that the vehicle may continue to drive safely even in the event of a defect in a drive train element between the first drive unit and the second drive unit, the torque portion used for charging the energy storage device is reduced to a minimum torque, while the torque excess, which is reduced in the event of a defect in the drive train element but still exceeds the minimum torque, is utilized to propel the vehicle. | 07-28-2011 |
| 20110202215 | METHOD AND DEVICE FOR OPERATING A HYBRID DRIVE OF A VEHICLE - In a method for operating a hybrid drive of a vehicle, which is driven by a combustion engine and an electric motor, the electric motor is supplied with energy from an energy store having a power reserve and the power of the combustion engine is supplemented by the power of the electric motor during a hybrid drive operation. In a situation in which the vehicle is to be removed as quickly as possible from a dangerous situation, the energy supplied from the energy store to the electric motor is supplied from the power reserve of the energy store when a dangerous situation is detected. | 08-18-2011 |
| 20110219772 | HYBRID DRIVE SYSTEM - A hybrid drive system for a motor vehicle includes an internal combustion engine and at least one electric motor, each driving wheels of the motor vehicle. The internal combustion engine is coupled to the corresponding wheels via a first multispeed transmission. The electric motor is coupled to the corresponding wheels via a second multispeed transmission. | 09-15-2011 |

| 20080243654 | Invoicing methods and systems for processing convergent contract accounts - Systems and methods consistent with the invention relate to the processing of invoices. According to one exemplary embodiment, a method for processing invoices associated with service contracts may comprise receiving data associated with a first service contract. The method may then analyze the first service contract data based on a processing rule. The method may then determine, based on the analyzed first contract data, whether the received first service contract data relates to an existing service contract. The method may then process an invoice associated with the first service contract based on the determination of whether the received first service contract data relates to an existing service contract. | 10-02-2008 |

| 20110198786 | Method and device for the continuous creation of a bainite structure in a carbon steel, particularly in a strip steel - A method continuously creates a bainite structure in a carbon steel, especially a strip steel by austenitizing the carbon steel; introducing the austenitized carbon steel into a bath containing a quenching agent; adjusting the carbon steel to the transformation temperature for bainite and maintaining the transformation temperature for a certain period of time; and then cooling the carbon steel. The carbon steel stays in the bath until a defined percentage of the bainite structure relative to the total structure of the carbon steel has formed. Residues of the quenching agent are removed from the surface of the carbon steel by blowing the same off when the carbon steel is discharged from the bath, and the remaining structure components of the carbon steel are then transformed into bainite in an isothermal tempering station without deflecting the carbon steel at all. | 08-18-2011 |
