  • Patent number: 11406745
    Abstract: This disclosure relates to a method for determining a fluid balance between a first volume flow in a first section of a fluid circuit and a second volume flow of a second section of the fluid circuit. The method may also include adjusting, assuming or detecting a first temperature in the first section of the fluid circuit and a second temperature in the second section of the fluid circuit, or detecting a temperature difference between the first and the second sections. The method may also include detecting a second volume flow in a second section of the fluid circuit and forming a balance from at least the first volume flow and a corrected value of the second volume flow. The corrected value is determined from the detected second volume flow and the second temperature and/or the temperature difference.

  • Patent number: 9750668
    Abstract: The present invention relates to an emulsion concentrate containing water-insoluble oil components (A), hydrophilic non-ionic emulsifiers (B), lipophilic co-emulsifiers (C), polyols (D) and water; which comprises less than 50% by weight of water-insoluble oil component (A), based on the total weight of the concentrate, and comprises components (A), (B) and (C) and (D) in a ratio by weight A:B:C:D=1:(0.25-0.6):(0.25-0.6):(0.45-0.65). The invention further relates to the use of these emulsion concentrates, and also to preparations and paper products, non-woven products or textile products for body care and personal cleansing, which comprise water-insoluble oil components (A), hydrophilic non-ionic emulsifiers (B), lipophilic co-emulsifiers (C), and polyols (D) in a ratio by weight A:B:C:D=1:(0.25-0.6):(0.25-0.6):(0.45-0.65).
