  • Patent number: 8273695
    Abstract: Improved lubricant and surface conditioner forming composition containing oxa acids and their methyl esters corresponding to general formula (I): H3C—(CH2)n—CH?CH—(CH2)m—O—(CH2CH2O)x—CH2—C(?O)—OR??(I) where each of m, n and x, which may be the same or different, is a positive integer and R represents H or CH3, when dissolved and/or dispersed in water is effective in reducing COF values on substrates that have been contacted with such a lubricant and surface conditioner forming composition and subsequently dried, even when the substrates have been conversion coated and rinsed before any contact with the lubricant and surface conditioner forming composition. Materials according to general formula (I) may be used together with other surfactants, including some constituents of previously known lubricant and surface conditioner forming compositions to provide improvements in COF, waterbreak performance, water drainage and resistance to dry-off of the conditioner.

  • Publication number: 20120199421
    Abstract: Method and System of lubricating at least one moving part with a medium. The medium includes a dissolved mixture of lubricant and compressed gas. The amount of lubricant and compressed gas may be controlled in forming the dissolved mixture in response to input conditions. A user and/or external factors may be used to determine the input conditions. In response to the input conditions the amount of lubricant and compressed gas is delivered to the moving part that is housed in a pressurized chamber. The properties of the dissolved mixture can be adjusted, whereby the properties may include, but are not limited to, the following: viscosity, temperature, and thermal conductivity. This adjustment to the gas may be accomplished, for example, by releasing gas from the pressurized chamber in an amount to adjust the properties. In a further approach, lubricant may be scavenged from the pressurized chamber by returning surplus lubricant to its original source or other designated location.
