20130021019 | Device and method for detecting a polarity reversal on a low voltage side of a dc voltage transformer in a dual-voltage vehicle electrical system - A device and a method for detecting a polarity reversal on a low voltage side of a DC voltage transformer in a dual-voltage vehicle electrical system, particularly in a motor vehicle. A current flow is enabled, in this instance, in a connecting line on the low voltage side of the DC voltage transformer by a controllable switching element, a current is detected in a connecting line on the low voltage side of the DC voltage transformer, with the aid of a current sensor system, the direction of the detected current is evaluated by an evaluation unit and a polarity reversal is detected if the direction of the detected current differs from an expected current direction. | 01-24-2013 |
20130085635 | METHOD FOR DETERMINING A POWER LIMITING VALUE FOR AN ELECTRIC MACHINE IN A VEHICLE, COMPUTER PROGRAM AND CONTROL UNIT FOR CONTROLLING AN ELECTRIC MACHINE IN A VEHICLE - In a method for determining a power limiting value for an electric machine in a vehicle, the electric machine being assigned an energy storage device, an intermediate power value is calculated from a maximally allowable current of the energy storage device and an instantaneous voltage. A corrected intermediate power value is determined by adding at least one power loss to the intermediate power value. A first correction value is determined for reducing the absolute value of the corrected intermediate power value if an instantaneous power of the energy storage device is greater than the absolute value of the calculated intermediate power value. The power limiting value is determined by superimposing the first correction value on the corrected intermediate power value. | 04-04-2013 |

20140125268 | METHOD AND DEVICE FOR OPERATING AN ELECTRICAL MACHINE HAVING SEPARATE EXCITATION - A method and a device for operating an electrical machine having separate excitation, especially a synchronous machine. With the aid of a sensor system, a variable characterizing a rotor temperature and/or a stator temperature are/is determined, and an excitation current and stator currents for the electrical machine are specified by a control unit as a function of the variable characterizing the rotor temperature and/or the stator temperature, at least in specifiable operating ranges. | 05-08-2014 |

20110269999 | PROCESS FOR DEHYDROHALOGENATION OF HALOGENATED ALKANES - A process for the manufacture of halogenated olefins in semi-batch mode by dehydrohalogenation of halogenated alkanes in the presence of an aqueous base such as KOH which simultaneously neutralizes the resulting hydrogen halide. During the process, aqueous base is continuously added to the haloalkane which results in better yields, lower by-product formation and safer/more controllable operation. | 11-03-2011 |
