  • Publication number: 20150275126
    Abstract: This disclosure relates to lubricating engines using formulated lubricating oils to reduce wear and improve engine fuel efficiency. The formulated lubricating oils contain a major amount of a nonpolar lubricating oil base stock and a minor amount of one or more polar lubricating oil additives. The one or more polar lubricating oil additives include swollen inverse micelles dispersed in the nonpolar lubricating oil base stock. The swollen inverse micelles include (i) a liquid polar core containing a polar solvent and one or more polar lubricating oil additives having solubility in the polar solvent, and (ii) a layer of liquid surfactant molecules enclosing the liquid polar core in which polar heads of the liquid surfactant molecules are oriented towards the liquid polar core. A method of improving solubility of polar lubricating oil additives in a nonpolar lubricating oil base stock is also provided.

  • Patent number: 8623796
    Abstract: This invention is directed to a lubricant composition that is comprised of a continuous phase and a discontinuous phase, i.e., a two phase lubricant composition. The continuous phase and the discontinuous phase of the lubricant of this invention are oil or oil type compositions that are essentially insoluble in one another. The lubricant composition is comprised of a continuous phase base oil that is comprised of a low viscosity Group II, III, IV or GTL base stock or a blend of at least two of the Group II, III, IV and GTL base stocks, optionally including a low viscosity Group V base stock, with the continuous phase base oil having, independently, a viscosity of from 1 to 100 cSt at 100° C. The lubricant composition is further comprised of a discontinuous phase that is comprised of an ester composition having a mean average droplet size of from 0.01 microns to 20 microns, in which the ester composition is comprised of an ester compound having no ether linkages.

  • Publication number: 20120302478
    Abstract: This invention provides a method for producing a lubricant composition that is comprised of a continuous phase and a discontinuous phase. The method involves mixing together high viscosity ester, ether or combination thereof, and polar diluent or solvent, to produce a solution. The solution is then added to a low viscosity Group IV base oil to produce a discontinuous phase dispersed throughout a continuous phase.

  • Publication number: 20040240318
    Abstract: A method and apparatus for slowing the rise of air bubbles for large-scale applications such as bubble curtains for suppressing noise in marine seismic surveys. Bubble rise time is increased by a chemical additive which either retards bubble coalescence or produces smaller bubbles through wetting agent properties, or a combination of both.

  • Patent number: 5618329
    Abstract: The present invention provides an enhanced biodegradation process by applying to petroleum contaminated soil or water essential microbial nutrients in a form capable of releasing the nutrients over time at a rate which, at 25.degree. C., is substantially linear. Importantly, in a preferred embodiment of the present invention, the microbial nutrients that are applied to the soil or water are in a form such that the release of nutrients at 38.degree. C. will be greater than that at 25.degree. C. by a factor of about 2.5 to 6.0, and preferably from a factor of about 3 to about 5.0.
