  • Patent number: 8021885
    Abstract: The present invention concerns a method for the determination of the oxidative stability of a lubricating fluid, comprising the steps of: introducing a sample of the lubricating fluid under test in an reaction cell; introducing catalytic amounts of a catalyst to the reaction cell; heating the cell to the oxidation temperature of the lubricating fluid and maintaining this temperature; delivering oxygen containing gas at constant flow rate through the cell over the course of the reaction; delivering a gas comprising nitrogen dioxide at a constant flow rate through the cell for a specified time; applying and maintaining a specified vacuum on the reaction cell; allowing the mixture to react for a specified time; measuring the viscosity of the oxidized lubricating fluid. Additionally, the present invention describes an apparatus for the determination of the oxidative stability of a lubricating fluid.

  • Patent number: 7553673
    Abstract: The present invention describes use of use of a metal compound to control the quality of a functional fluid. Additionally, the present invention concerns a method for controlling the quality of a functional fluid comprising the steps of: adding a metal compound to a component of a lubricant; mixing the component with a base oil; measuring the concentration of the metal compound in the functional fluid; and comparing the expected concentration of the metal compound with the measured concentration.
