  • Patent number: 6063744
    Abstract: A cleaning and lubricant formulation for use on spindles on cotton picker or harvesting machines that simultaneously cleans and lubricates the surface of the spindles. The formulation features a major proportion of water and amounts of unsaturated fatty acids, glycol ether and alcohol solvents, nonionic surfactant, amide cosurfactant, and polycarboxylic acid. An alkalizing agent is added to control the pH of the resulting formulation. The cleaning and lubricant formulation exhibits excellent cleaning and lubrication properties without utilizing petroleum oil that can contaminate cotton fields, water supplies or the harvested cotton.

  • Patent number: 5985804
    Abstract: It is disclosed that succinic acid and its derivatives that contain a branched aliphatic group on the 2 or alpha position of succinic acid form surfactants that exhibit a high order of or bioresistance to bacteriological degradation. Further, it has been discovered that these novel surfactants can be employed to prepare novel oil-in-water emulsions with lube oils such as mineral oil that are effective as cutting fluids for machining operations but provide an improved resistance to biodegradation to the cutting oil so formulated, without resorting to the inclusion of conventional biocides in the formulation. It has also been discovered that the bioresistance of the cutting fluid emulsion formulation can be further enhanced by using a branched aliphatic hydrocarbon oligomer or polymer as the lubricative component in the formulation. Cutting fluid emulsions so formulated are effective fluids in prolonging tool life and facilitating machining operations.

  • Patent number: 5663130
    Abstract: The invention pertains to oil soluble copolymers derived from ethylene and 1-butene which have a number average molecular weight between about 1,500 and 7,500, at least about 30 percent of all polymer chains terminated with ethylvinylidene groups, and ethylene-derived content of not greater than about 50 weight percent, and which form solutions in mineral oil free of polymer aggregates, as determined by light scattering measurements. Lubricating oil additives, particularly dispersants, produced by the functionalization and derivatization of these copolymers have enhanced performance (e.g., improved dispersancy and pour point) in lubricating oil compositions, attributable in part to the combination of properties characterizing the copolymers.
