  • Quaternary ammonium salt containing compositions that provide balanced deposit control and wear performance without seal compatibility issues
    Patent number: 9683194
    Abstract: The invention relates to lubricating compositions, processes of making such lubricating compositions, and method of using such lubricating compositions. The lubricating compositions of the present invention include a dispersant comprising a quaternary ammonium salt, a phosphorus-containing compound, a metal dialkyldithiophosphate, a derivative of a hydroxyl carbonyl compound and an amine and/or an alcohol. These compositions provide balanced deposit control and wear performance without causing any seal compatibility issues.

  • Wettable polyester fibers and fabrics
    Patent number: 7842630
    Abstract: The present invention is aimed at a method of providing wettability to polyester fibers or filaments, to woven or nonwoven fabrics made therefrom and to resultant articles of manufacture. The method comprises melt extruding a mixture comprising a polyester and one or more alkyl metal sulfonates where the metal is Na, Li or K and the alkyl is straight or branched chain alkyl of 12 to 15 carbon atoms, or is straight or branched chain alkenyl of 12 to 18 carbon atoms. The alkyl metal sulfonates are present from about 2% to about 5% by weight based on the weight of the polyester. A post treatment step such as an alkaline treatment step is not included. The melt extrusion mixtures do not include certain additives such as polyoxyalkylene compounds, alkylmonoethonolamide compounds, alkyldiethanolamine compounds and polyetheramide compounds.
