20090176903 | FOAMABLE COMPOSITIONS BASED ON EPOXY RESINS AND POLYESTERS - Expandable, thermally curable compositions containing at least one epoxy resin, at least one polyester, at least one blowing agent, and at least one curing agent are useful as adhesives and structural reinforcement materials. When foamed and adhered to a metal substrate surface, such polyester-modified foamable compositions can exhibit improved adhesion to the substrate surface after exposure to a corrosive environment, as compared to compositions that do not contain polyester. Furthermore, these compositions can exhibit improved flow properties in the uncured state at temperatures between 50 and 100° C. They are granulatable, with the granules produced thereby having non-tacky surfaces at room temperature and being capable of being readily processed into molded objects by injection molding processes. | 07-09-2009 |

20120187884 | METHOD AND APPARATUS FOR FAILSAFE MONITORING OF A MOVEMENT VARIABLE ON AN ELECTRICAL DRIVE - A first and a second drive current for an electrical drive are generated as a function of a nominal value for a movement variable, such as drive torque or rotational speed. An alternating magnetic field is generated in the drive by the drive currents. The alternating magnetic field causes movement of the drive. A first measurement signal and a second measurement signal are determined by a measurement device. The two measurement signals represent the first drive current and the second drive current. A field-producing direct-axis current component and a torque-producing quadrature-axis current component are determined as a function of the first and second measurement signals. In addition, an actual value of the movement variable is determined as a function of the measurement signals. At least one of the drive currents is generated with a variable test current component which forms a test pattern for checking the measurement device. | 07-26-2012 |

20100253079 | WIND ENERGY INSTALLATION WITH A HEATING DEVICE - A wind energy installation connected to a network. The installation includes a tower and a pod having a wind rotor and a generator driven by the wind rotor. The installation further includes a converter configured to output electrical power, a control device provided with a temperature sensor and a heating device, and a preheating module. The preheating module includes a thermal switch configured to monitor a temperature of at least one component of the wind energy installation and a monitoring unit having an output device. The monitoring unit operates the heating device until the thermal switch reaches a threshold, whereupon the output device transmits an enable signal to start the wind energy installation. Operational reliability of the wind energy installation in low ambient temperatures can be thus improved. | 10-07-2010 |
