    Abstract: Process for applying a polyvinyl ester dispersion-based adhesive by means of nozzle application and use of polyvinyl ester dispersion-based adhesives A description is given of an application process for polyvinyl ester dispersion-based adhesives through nozzles to a substrate, wherein an aqueous, primarily emulsifier-stabilized vinyl ester polymer dispersion having a solids content of at least 40% by weight, a viscosity of less than 8000 mPas, and a vinyl ester polymer glass transition temperature of −30 to +40° C. is supplied to the nozzle and is applied from the nozzle, in the form of a thin jet or of a predeterminedly interrupted thin jet, to the substrate. The process can be implemented for long periods without interruption, and the adhesive bonding takes place at high speed.

    Abstract: In the current invention, a paraffin or waxy substance is added to a solvent-based parquet adhesive to generate a contiguous film that forms a barrier layer between the adhesive and the surrounding air. This barrier prevents volatile solvents from escaping and contaminating the surrounding air before parquet laying. The protective film can then be destroyed by laying down the parquet strips on the substrate. This process overcomes disadvantages to using state of the art solvent-based adhesives which are susceptible to undesirable swelling of parquet wood and contamination of air.

    Abstract: The invention relates to a control method for the electrical actuator of a variable valve train, the actuator being embodied in the form of a worm gear in which a sensor detects a position value (measured position value) of an eccentric shaft, a control difference is generated in a feedback branch with the use of the measured position value, and the electrical actuator is actuated. To suppress interferences in the control system, an observer value is formed that is associated with the position value from the pulse duty factor of the pulse-width modulation. The observer value is composed to a comparison value formed from the measured position value. The detected measured position value is not accepted if the deviation of the observer value from the comparison value exceeds a defined limit.
