  • Patent number: 8450254
    Abstract: The present invention provides a modified solid stick composition comprising a thermosetting plasticizer, a resin, a lubricant, a friction modifier, or a combination thereof. The solid stick compositions may be used for application between two metal surfaces in sliding and rolling-sliding contact such as steel wheel-rail systems including mass transit and freight systems. A method of reducing energy consumption, or controlling friction between a metal surface and a second metal surface by applying the solid stick composition to one or more than one of the metal surfaces, is also provided.

  • Publication number: 20130096039
    Abstract: A method for heating materials by application of radio frequency (“RF”) energy is disclosed. For example, the disclosure concerns a method and apparatus for RF heating of petroleum ore, such as bitumen, oil sands, oil shale, tar sands, or heavy oil. Petroleum ore is mixed with a substance comprising mini-dipole susceptors such as carbon strands. A source is provided which applies RF energy to the mixture of a power and frequency sufficient to heat the mini-dipole susceptors. The RF energy is applied for a sufficient time to allow the mini-dipole susceptors to heat the mixture to an average temperature greater than about 212° F. (100° C.). Optionally, the mini-dipole susceptors can be removed after the desired average temperature has been achieved. The susceptors may provide advantages for the RF heating of hydrocarbons, such as higher temperatures (sufficient for distillation or pyrolysis), anhydrous processing, and greater speed or efficiency.

  • Publication number: 20130079262
    Abstract: This invention relates to carbon-based materials as anti-friction and anti-wear additives for advanced lubrication purposes. The materials have various shapes, sizes, and structures and are synthesized by autogenic reactions under extreme conditions of high temperature and pressure. The lubricant compositions comprise carbon-based particles suspended in a liquid hydrocarbon carrier. Optionally, the compositions further comprise a surfactant (e.g., to aid in dispersion of the carbon particles). Specifically, the novel lubricants have the ability to significantly lower friction and wear, which translates into improved fuel economies and longer durability of mechanical devices and engines.

  • Patent number: 8349774
    Abstract: Provided are a mixed nano-lubricating oil and a method for preparing the same. The method for preparing a mixed nano-lubricating oil includes the steps of: (a) preparing a mixed solution by adding and mixing a nanopowder and a dispersant to a solvent and pulverizing the nanopowder to a primary particle level; (b) modifying the surface of the nanopowder; (c) substituting the solvent of the mixed solution to a lubricating oil; and (d) mixing at least two nano-lubricating oils prepared using physically and chemically different nanopowders. According to the present invention, it is possible to improve the wear resistance and the load resistance at the same time by mixing at least two kinds of lubricating oils having excellent wear resistance or load resistance.

  • Publication number: 20130005619
    Abstract: The present invention provides a lubricating oil composition for reducing a friction coefficient adjacent to the surface of being subjected to lubrication. In particular, the present invention provides nanoporous particles capable of being dispersed in a lubricating oil composition comprising base oil having a lubricant viscosity. Since the nanoporous particles having nano-sized, oil soluble pores according to the present invention reduces a friction coefficient, and in the long term, gradually releases an effective ingredient, the lubricating oil composition comprising the same of the present invention can act as a reducing agent for reducing friction for a long period of time, and thereby, exhibit excellent lubricant effects.
