  • Patent number: 11655320
    Abstract: A mixture includes at least two radically curable compounds as a backbone resin, and is useful in reactive resins. In particular, the mixture reduces the viscosity of such reactive resin-containing mixtures and thus the dispensing forces required for ejecting the reactive resin components produced therefrom. The mixture also increases the performance of the reactive resins containing such mixtures and of the reactive resin components produced therefrom. Further, said reactive resins and the reactive resin components thereof are useful for construction purposes, in particular for chemical fastening.

  • Patent number: 11284566
    Abstract: A combine harvester for carrying out an agricultural harvesting process has a plurality of working units and a driver assistance system for controlling at least some of the working units. The combine harvester accommodates as working units a chaff cutter for comminuting harvested produce and a produce distributing arrangement in the rear area of the combine harvester downstream of the chaff cutter for distributing harvested produce on the field soil in adjustable throw directions. The respective throw direction comprises vector components of a horizontal throw direction and a vertical throw direction. The driver assistance system is adapted to optimize the control of the produce distributing arrangement by at least one of the substrategies including “throw direction correction” and/or “inclination-dependent produce distribution” and/or “produce distribution in longitudinal direction” and/or “produce distribution in transverse direction” with respect to at least one optimization criterion.

  • Publication number: 20200095367
    Abstract: Low-viscosity urethane methacrylate compounds are used as a backbone resin in reactive resins. In particular, the compounds are for lowering the viscosity of reactive resins containing such mixtures and thus the extrusion forces of reactive resin components produced therefrom and also for increasing the performance of reactive resins and reactive resin components produced therefrom containing such compounds. Furthermore, said compounds and their reactive resin components are used for construction purposes, in particular for chemical fastening.

  • Patent number: 10506748
    Abstract: A corona shielding system for an electric machine, for example a high-voltage machine, such as a generator, for generating electrical energy, an electric motor or else other electric operating means having a relatively high rated voltage, such as transformers, bushings, cables, etc, is disclosed. The corona shielding system may include a filler mixture including both planar and spherical particles. Therefore, the electrical conductivity, which is good in the presence of only planar particles in two spatial directions but is very poor in the third, can be adjusted anisotropically in a targeted manner.

    Abstract: An energy supply unit for a measuring device for determining and/or monitoring a physical or chemical, process variable of a medium. Included is at least one voltage limiting unit and/or at least one current limiting unit in the energy supply unit, wherein the voltage limiting unit is embodied in such a manner that arising voltages remain under a value, which leads to an explosion in an explosion-endangered area, and wherein the current limiting unit is embodied in such a manner that arising currents and/or heatings associated therewith remain under a value, which leads to an explosion in an explosion-endangered area.
