摘要:
A lubricant composition, method for reducing a boundary friction coefficient of a lubricant composition, and method for improving fuel economy. The lubricant composition includes a base oil, a) a metal-containing phosphorus antiwear compound in an amount sufficient to provide from about 100 to about 1000 ppm by weight phosphorus based on a total weight of the lubricant composition, and b) an oxygen-polymerized vegetable oil, different from the base oil. The base oil is present in the lubricant composition in an amount from about 50 wt. % to about 99 wt. % based on the total weight of the lubricant composition.

There is disclosed an automatic transmission fluid containing an improved demulsifier additive being a combination of an acylated alkoxylated isopentylphenolic resin and a propoxylated-ethoxylated amylphenolic resin, the additive being effective at concentrations of 30 to 50 ppm.
摘要:
A sliding screen system (101) for a sliding screen comprising a linear slide bar (110) and at least one sliding member (120, 120′). The linear slide bar (110) has a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide bar (110) with low friction. The sliding system (101) is arranged to support a sliding screen (130), such as a sliding door or a sliding curtain, connected to the sliding member (120) to allow for linear movement of the sliding screen (130) along the longitudinal axis of the linear slide bar (110).

摘要:
There is provided a lubricating composition including a lubricating base containing an asymmetric sulfurized oxymolybdenum dithiocarbamate of the formula (1); a symmetric sulfurized oxymolybdenum dithiocarbamate of the formula (2); and a phenolic or aminic antioxidant. (wherein R1 to R5 are each a hydrocarbon group, provided that R1 to R4 are not concurrently the same group; and X1 to X8 are each a sulfur atom or an oxygen atom.) This lubricating composition meets both the required solubility of additives in base oils and long drain properties concurrently.
