Organic Phosphorus Compound Salt Of The 1,3-hetero Ring Compound, Or An Organic Phosphorus Compound Is Present Patents (Class 508/286)
  • Publication number: 20150141306
    Abstract: A slideway lubricating oil composition, additive concentrate, method of lubricating sliding parts. The lubricating oil includes a base oil; a metal-free friction modifier; and a metal-free, sulfur-free, phosphorus containing anti-wear/extreme pressure agent. The lubricating oil provides a lower coefficient of friction for non-metal sliding surfaces than for metal sliding surfaces.

  • Publication number: 20130130953
    Abstract: A grease with improved water resistance is based on a combination of a polyamide thixotrope with a water insoluble thickener, preferably a lithium soap/complex thickener and an antioxidant/corrosion inhibitor/antiwear additive package. The improvement is maintained when highly effective or aggressive rust inhibitors which normally tend to degrade water wash out resistance are present in the grease. Another advantage is that resistance to fretting is significantly improved to the extent that the greases containing these components are capable of achieving a high level of resistance to false brinelling. The greases are particularly useful for application in wind turbine bearings.

  • Patent number: 5866520
    Abstract: A lubricant composition is disclosed that is suitable for direct fuel injected, crankcase-scavenged two-stroke cycle engines. That lubricant composition has a major amount of at least one oil of lubricating viscosity, a minor amount of a lubricity additive, a polyalkyl amide, an imidazoline, a polyisobutylene, and a functionalized polyisobutylene. The lubricity additive contains glycerol monooleate, an acid aliphatic aromatic amine-phosphate, and sodium sulfonate. The acid aliphatic aromatic amine-phosphate has a phosphorus/oxygen atom ratio of from 4.0:1 to 4.5:1, and at least 1.2 equivalents of acid to 1.0 equivalents of base.
