Heavy Metal Or Aluminum In The Same Compound With Alkali Or Alkaline Earth Metal Patents (Class 508/381)
  • Patent number: 8772208
    Abstract: The present invention provides an additive agent to be added to oil and comprising weak basic hydrotalcite. At the time of adding a mixture of hydrotalcite of 1 weight % and water by 3 weight % to the oil where a hydrogen ion exponent is within a range of 6 to 7 for stirring, the weak basic hydrotalcite is hydrotalcite where the obtained oil indicates the hydrogen ion exponent within a range of 6 to 7. Such an additive agent can be accommodated in an oil filter (36) for use.

    Abstract: An ionic compound is represented by formula (1): AM(OY1)(OY2)(OY3)(OY4). A is a group 1 element. M is a group 13 element. Y1 is one selected from an oligoalkylene ether group, an oligoalkylene thioether group, and an oligoalkylene amino group and includes an electron donating group on carbon that is located in one of ?-? positions with respect to oxygen atom adjacent to M. Y2, Y3, and Y4 are the same each other or different from each other or cross-linked to each other. Y2, Y3, and Y4 are each any one of an alkyl group, an alkyl group with a fluorinated terminal, an aryl group, and one selected from the group consisting of an oligoalkylene ether group, an oligoalkylene thioether group, and an oligoalkylene amino group and including an electron donating group on carbon that is located in one of ?-? positions with respect to oxygen atom adjacent to M.

  • Patent number: 8188016
    Abstract: A lubricant composition capable of preventing a rolling surface of a bearing from flaking owing to hydrogen embrittlement. The bearing is lubricated with the lubricant composition which is a lubricating oil or grease. The lubricant composition contains a molybdate and an organic acid salt. At least one molybdate is selected from sodium molybdate, potassium molybdate, and lithium molybdate. The organic acid salt is a sodium salt of an organic acid having one to 20 carbon atoms. The lubricant composition forms a film containing a molybdenum compound in addition to an iron oxide film on a worn surface of the bearing or on a fresh surface of an iron-based metal generated by wear. The bearing is used as a rolling bearing for use in electric parts and auxiliary machines of a vehicle. The bearing is also used as a bearing, for a motor, in which the lubricant composition is sealed.

  • Patent number: 6858568
    Abstract: Lubricants are taught that can quickly and easily form a lubricating layer on a metal surface of a metal before plastic processing. Such lubricants preferably include a primary lubricating agent or component having a bridge complex that satisfies the following conditions: (1) the complex contains at least two central metal atoms; (2) at least one first multidentate ligand forms a bridge between two central metal atoms; and (3) at least one second multidentate ligand is bound to at least one central metal atom and has at least one coordinating atom that can coordinate with metal atoms, but which is not coordinated with any of the central metal atoms or is only partially coordinated with at least one of those central metal atoms. A third multidentate ligand is preferably also bound to one of the central metal atoms and may preferably include at least two sulfur atoms that are coordinated to the central metal atom.
