  • Patent number: 9657251
    Abstract: A wear and/or friction reducing additive for a lubricating fluid in which the additive is a combination of a moderately hydrophilic single-phase compound and an anti-wear and/or anti-friction aqueous salt solution. The aqueous salt solution produces a coating on boundary layer surfaces. The lubricating fluid can be an emulsion-free hydrophobic oil, hydraulic fluid, antifreeze, water, or a water-based lubricant. Preferably, the moderately hydrophilic single-phase compound is sulfonated castor oil and the aqueous salt solution additionally contains boric acid and zinc oxide. The emulsions produced by the aqueous salt solutions, the moderately hydrophilic single-phase compounds, or the combination thereof provide targeted boundary layer organizers that significantly enhance the anti-wear and/or anti-friction properties of the base lubricant by decreasing wear and/or friction of sliding and/or rolling surfaces at boundary layers.

  • Patent number: 9023773
    Abstract: Lubrication additives of the current invention require formation of emulsions in base lubricants, created with an aqueous salt solution plus a single-phase compound such that partitioning within the resulting emulsion provides thermodynamically targeted compounds for boundary layer organization thus establishing anti-friction and/or anti-wear. The single-phase compound is termed “boundary layer organizer”, abbreviated BLO. These emulsion-contained compounds energetically favor association with tribologic surfaces in accord with the Second Law of Thermodynamics, and will organize boundary layers on those surfaces in ways specific to the chemistry of the salt and BLO additives. In this way friction modifications may be provided by BLOs targeted to boundary layers via emulsions within lubricating fluids, wherein those lubricating fluids may be water-based or oil-based.

  • Patent number: 8182842
    Abstract: Systems and methods for the use of compounds from the Hofmeister series coupled with specific pH and temperature to provide rapid physico-chemical-managed killing of penicillin-resistant static and growing Gram-positive and Gram-negative vegetative bacteria. The systems and methods represent the more general physico-chemical enhancement of susceptibility for a wide range of pathological macromolecular targets to clinical management by establishing the reactivity of those targets to topically applied drugs or anti-toxins.

  • Publication number: 20060086550
    Abstract: An air intake system including a filter, a first pipe, a fan, and a second pipe. The filter is located behind the grill or inside the fender well outside the engine bay so the filter does to not draw any hot under-hood air. The filter is attached to the first pipe which has spiraling groves cut into the inside of the pipe to transform the turbulent air drawn in through filter into a smooth spiraling stream which provides a more consistent mixture of oxygen. The first pipe is attached to the fan wherein the fan increases the velocity of the air. The fan is attached to the second pipe which has spiraling groves in the same direction as the spiraling grooves in the first pipe. The second pipe is attached to the engine's air box by an airtight connection and delivers the smooth spiraling stream of air at a relatively high velocity to the engine.
