  • METHOD FOR PARAMETERIZING A SENSOR ARRANGEMENT COMPRISING MULTIPLE LOAD SENSORS OF A ROTOR BLADE OF A WIND POWER INSTALLATION
    Publication number: 20230417222
    Abstract: A method for parameterizing a sensor arrangement comprising multiple load sensors of a rotor blade of a rotor of a wind power installation for acquiring at least one load variable, which is representative of a load that acts on the rotor blade, wherein the rotor blade has at least three load sensors, each of the load sensors records a load-dependent physical variable of the rotor blade and outputs a variable representative thereof as the acquired sensor variable, for calculating the at least one load variable from the sensor variables, at least one overall calculation rule is used, forming a relationship between the acquired sensor variables of all the load sensors and the at least one load variable of the rotor blade, and having multiple calculation parameters, and, for parameterizing the sensor arrangement, the calculation parameters of the overall calculation rule are determined while at the same time taking into consideration acquired sensor variables of all the load sensors.

  • POLYESTER POLYMERIZATION PROCESS
    Publication number: 20130243984
    Abstract: The present invention relates to a process for producing PET based on titanium catalyst having acceptable properties for resin used in the production of bottles for beverages. More particularly the invention relates to a process in which the incoming pre-polymer temperature is higher than the final outlet temperature in the final melt phase polycondensation reactor.
