Abstract:
A system reclaiming contaminated water includes a heat exchanger that receives the contaminated water and converts at least a portion of the contaminated water into steam and collects at least a portion of the contaminants within the heat exchanger. A thermal transfer fluid is heated by a solar concentrator during daytime and by a biofuel combustion device during nighttime. The heated fluid is circulated through the heat exchanger to heat the contaminated water. A steam engine is coupled to a generator, the steam engine receives the steam from the heat exchanger to drive the generator to provide power for the system. Steam exhausted from the steam engine is supplied to supplemental heat loads. The collected contaminants are directed to an evaporation device to remove residual liquid.
Abstract:
The invention relates to a method for monitoring the condition of rotor blades for wind turbines. It is therefore the object of the invention to increase the accuracy of the monitoring of the condition of rotor blades of wind turbines and to allow a localization of faults or defects and their exact description. In the method in accordance with the invention, eigenvibrations of a rotor blade occurring globally at the rotor blade and locally guided elastic waves are permanently detected with time and spatial resolution using a sensor network and actuator network attached to the rotor blade or using a network arrangement of ultrasound transducers. In addition, elastic waves which are guided periodically at predefinable time intervals and which are respectively emitted by an actuator or ultrasound transducer and detected by sensors or ultrasound transducers are in so doing inspected for variations of the emitted waves.
Abstract:
The present invention related to particles and composite particles, their uses and a novel process for producing them from alkoxysilyl-group-carrying alkoxylation products.
Abstract:
Household care compositions having a linear polydimethylsiloxane-polyether copolymers with amino and/or quaternary ammonium groups, obtainable by the reaction of organopolysiloxanes functionalized with secondary aminoalkyl groups with the reaction products formed from compounds containing epoxy groups and amines, the use thereof and process for preparation thereof.
Abstract:
Alkoxysilyl-functional polyether-siloxanes and processes for preparing them by noble metal-catalysed SiC coupling of hydrogensiloxanes having SiH groups with unsaturated polyethers bearing alkoxysilyl groups or by alkoxylation of polyethersiloxanes or polysiloxanes by means of epoxy-functional alkoxysilanes in the presence of double metal cyanide catalysts.

Abstract:
Process for preparing polyether alcohols by polymerization by means of double metal cyanide catalysts (DMC catalysts), characterized in that, before or during the polymerization, one or more, optionally mixed additives consisting of compounds having one or more aromatic structures which may be monosubstituted or else polysubstituted and which have at least one hydroxyl group on the aromatic system are added to the reaction mixture.
Abstract:
A device for feeding fiber bands to a knitting machine, wherein the device includes a creel having at least one bobbin with at least one fiber band. Further, at least one feed drive driving at least one feeder roll, such that the fiber band is guided by the at least one feeder roll. Further still, a band storage including a motor driven control drive arranged to change the length of a variable length storage path for the at least one fiber band, wherein the band storage is arranged between the creel and the at least one feeder roll. A control device actuates the motor driven control drive and the at least one feed drive in a manner coordinated with one another.
