  • Patent number: 9040469
    Abstract: The invention relates to a lubricant in the form of grease or thick lubricating gel or transmission oil, as well as motor or universal oils with a myriad of applications. As a result of its contents presented in the patent application is characteristic of low coefficient of friction ranging from 0.055 to 0.062. As the main component, the contents of the discussed lubricant includes three or four stearates of metals or hydroxistearates of metals, which interact and cause a noticeable reduction of friction drag on the lubricated surfaces. Additionally, these substances may include a number of other solid or liquid elements, which maintain low friction drags and, furthermore, improve the lubricant through increasing its load capacity, antirust characteristics, shear strength, etc.

  • 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.
