  • Patent number: 9493724
    Abstract: In accordance with the present invention, it has been discovered that an additive which is substantially insoluble in, has low solubility in and/or is otherwise incompatible with a functional fluid, may be supplied to the functional fluid by use of a gel composition and/or a solid additive composition containing the additive, such that the functional fluid can receive the benefit of the supplied additive and/or contain levels of the additive not otherwise achievable by conventional delivery method due to the incompatibility of the additive with the functional fluid.

  • Patent number: 7918254
    Abstract: A method for creating a design on a surface comprising providing a template to overlay the surface upon which the design is to be created, forming a pattern of the design on the template for the design which is to be created on the surface, placing the template with the pattern of the design thereon on the surface, with a tool, tracing the pattern of the design on the template to form an impression on the surface below the template and removing the template leaving the impression of the design on the surface.

  • Patent number: 7435707
    Abstract: The invention relates to a novel emulsified composition containing (a) major amount of an aqueous phase, (b) a minor amount of an organic phase (c) a thickener and (d) a minor but effective amount of at least one emulsifier to emulsify the aqueous and organic phase resulting in a water in oil emulsifeid composition, in particular emulsified greases and emulsified coatings. Further, the present invention provides a process for making the emulsified composition.

  • Publication number: 20070148356
    Abstract: The invention relates to a novel method to use an emulsified material as a surface coating comprising the steps of: (a) applying an emulsified material to a surface of a substrate and (b) drying or allowing to dry the emulsified material as a surface coating on the substrate. The method allows for the precision application of the emulsified material with increased viscosity onto a surface. Additionally, the emulsified material surface coating can easily be removed if desired.

  • Publication number: 20040237383
    Abstract: A combustion modifier for an aqueous hydrocarbon fuel emulsion that reduces nitrogen oxides (NOx), hydrocarbons, carbon monoxide (CO) and particulate matter from the emissions of internal combustion engines. A class of combustion modifiers used in this invention contain nitrogen. The nitrogen-containing combustion modifiers are nitro compounds, hydroxylamines or salts thereof, nitrogen compounds having at least one strained ring group containing from 3 to 5 ring atoms, nitrites, nitramines and mixtures thereof. The non nitrogen-containing combustion modifier comprises compounds containing at least one strained ring compound.
