  • Apparatus and method for determining the air entrainment characteristics of liquids
    Patent number: 5965805
    Abstract: Described is an apparatus and a method to accurately determine the gas entrainment characteristics of liquids, such as automatic transmission fluids. The apparatus comprises a liquid reservoir, a conduit having an inlet and an outlet connected to the liquid reservoir so as to form a pressurized recirculating loop for the liquid in the liquid reservoir, a pump for moving the liquid through the conduit, and a means for admitting gas (such as air) into the conduit to aerate the liquid.

  • Power transmitting fluids improved anti-shudder durability
    Patent number: 5840663
    Abstract: The anti-shudder durability of power transmitting fluids, particularly automatic transmission fluids, is improved by incorporating a combination of low potency friction modifiers, alkyl phosphites, specific ashless dispersants and a corrosion inhibitor. The anti-shudder durability of these fluids may be further enhanced by inclusion of a metallic detergent.

  • Power transmitting fluids with improved anti-shudder durability
    Patent number: 5750476
    Abstract: The anti-shudder durability of power transmitting fluids, particularly automatic transmission fluids, is improved by incorporating a combination of low potency friction modifiers and phosphorus-containing compounds. The anti-shudder durability of these fluids may be further enhanced by inclusion of a metallic detergent and/or a polyol ester friction modifier.
