Abstract: Surfactants capable of releasing and/or dissolving polymers to form water-soluble or water-dispersible polymer solutions are disclosed. In addition, polymer compositions containing a water-in-oil emulsion comprising the surfactant are provided and can be used, for example, in methods of dissolving a polymer. Also disclosed are detergent compositions and methods of cleaning articles and/or membranes using the surfactants herein. These surfactants and polymer compositions can be used in various industries including for water clarification, papermaking, sewage and industrial water treatment, drilling mud stabilizers, and enhanced oil recovery.

Abstract: An electronic component for guiding a magnetic field comprises a core (20) of a magnetizable material, which has at least two spaced-apart legs (11a, 11b) with opposing surfaces (O11a, O11b) separated from one another by a gap (S). The component comprises at least one compressible molding (20), which is arranged compressed in the gap (S), the at least one molding (20) being in contact with the respective surfaces (O11a, O11b) of the at least two spaced-apart legs (11a, 11b).

Abstract: In order to control access to resources of a data processing system, a priority code is determined for an access request to at least one resource. A comparison code for granting access to the at least one requested resource is determined concerning an alternative use of the resource. For a totality of resource requests to the data processing system, an extreme value for a sum is determined via products of a corresponding priority code and of a number of resource accesses which can be granted in each case, taking into account a maximum capability of a requested resource. For a resource request, it is checked whether the priority code and the comparison code show a predetermined mutual relation. Access is granted depending on the extreme value determined and on the result of the check.
