Patent number: 5212235Abstract: This invention relates to the production of oil-in-water emulsifiers and emulsion stabilizers. More particularly, this invention relates to methods for the production of novel hydrophobically modified proteins which may be used as emulsifiers or to stabilize emulsions.This invention also relates to products incorporating these hydrophobically modified protein emulsifiers and emulsion stabilizers. These compounds may be used in many applications such as paints, dyes and cosmetics.Type: GrantFiled: December 27, 1990Date of Patent: May 18, 1993Assignee: Emulsan Biotechnologies, Inc.Inventors: Eirik Nestaas, Kevin R. Hrebenar, Jerome M. Lewis, George M. Whitesides

Patent number: 4934391Abstract: Methods and compositions are provided for the removal of soldering flux, screen inks and resists from contaminated surfaces. The compositions of the invention contain dibasic acid esters in combination with an appropriate emulsifying surfactant.Type: GrantFiled: February 2, 1989Date of Patent: June 19, 1990Assignee: 501 Petroleum Fermentations N.V.Inventors: Larry Futch, Kevin R. Hrebenar, Michael E. Hayes

Patent number: 4886519Abstract: This invention relates to the reduction of oxidized sulfur compound (SOX) emissions produced during combustion of sulfur (S)-containing combustible compounds. More particularly, this invention provides a method for reducing such emissions wherein the combustible compound is mixed with an admixture of a water soluble and a water insoluble sulfur sorbent. Use of such admixtures, remarkably, produces a reduction in the SOX level far greater than would be expected based on the activity of each sorbent alone. Extremely viscous hydrocarbons can be burned as preatomized fuels, which can also be mixed with sorbent admixtures. Clean burning fuels comprising sulfur-containing combustible compounds and sorbent admixtures are also provided.Type: GrantFiled: April 23, 1987Date of Patent: December 12, 1989Assignee: Petroleum Fermentations N.V.Inventors: Michael E. Hayes, Kevin R. Hrebenar, Jennifer L. Minor, Lawrence M. Woodworth
