Abstract:
The present invention relates to additives for use in lubricant compositions to processes for producing the additives, and to the use of the additives in lubricants and in systems that are lubricated. More specifically, the additive includes a capped particle comprising: (i) one or more core particles wherein the core particle is an inorganic particle having a dimension less than about 5 μm; and (ii) one or more multi-block copolymers attached to the inorganic particles, wherein the multi-block copolymer comprises a) at least one nonpolar polymer block; b) at least one first polar polymer block; and c) at least one second polar polymer block; wherein the nonpolar polymer block is interposed between the first polar polymer block and the second polar polymer block, the first polar polymer block is attached to the core particle, and at least a portion of the second polar polymer block is not attached to the core particle. When used in a lubricant to lubricate a metallic surface of a workpiece, the capped particle preferably adhere to the metallic surface of the workpiece.

Another method provided is a method comprising: providing a tubing comprising a first fluid located within a well bore such that an annulus is formed between the tubing and a surface of the well bore; providing an aqueous-based insulating fluid that comprises an aqueous base fluid, a water-miscible organic liquid, and a synthetic polymer; and placing the aqueous-based insulating fluid in the annulus.
Abstract:
A method and combustion system for reducing the formation of intake manifold deposits, such as including intake valve valves, and exhaust valve deposits in combustion engines by delivery of an organomolybdenum source from the vapor phase of an engine lubricant into a combustion chamber.
Abstract:
A coating and bonding composition is disclosed which includes a suspending agent, bonding agent, thinning agent, and a particulate fluoride anti-seize agent designed to bond a particulate fluoride film to the thread surface to prevent seizing and galling. A anti-seize lubricating composition is also disclosed where an environmentally friendly lubricating composition is applied as a top coat to the bonding composition and to methods for making and using the compositions.
Abstract:
The present invention is directed to a stable, soluble, antimicrobial composition concentrate comprising pyrithione or a pyrithione complex in an amount of from about 0.5% to about 30 weight percent, a zinc source in an amount of from about 0.1% to about 10%, and an organic amine component in an amount of from about 30% to about 80%, said percents being based upon the total weight of the composition concentrate. The invention is also directed to methods of controlling the growth of free-living microorganisms or biofilms using the antimicrobial composition of the invention, and products made using the antimicrobial composition of the invention.
Abstract:
The production of solid lubricant agglomerates by combining solid lubricant powder, an inorganic binder, other fillers if optionally desired, and a liquid to form a mixture, and driving off the liquid to form dry agglomerates which are subsequently classified by size or milled and classified by size to yield agglomerates of a desired size range. These agglomerates are then treated to stabilize the binder, thereby strengthening the binder and rendering it nondispersible in the liquid. The undesired size ranges can be readily recycled because the agglomerates with untreated binder can be reprocessed, thereby promoting high recovery rates.
Abstract:
A method for disinfecting microorganisms in metalworking fluids without leaving behind unacceptable amount of chemicals in the treated fluids. The method comprises passing the fluid in a recirculating cooling system through a filter, which contains a demand disinfectant, preferably an iodinated resin. The iodinated resin inhibits the growth of microorganism in the fluid, which is then cycled back into the system. The present invention also relates to a filter and system for disinfecting microorganisms in metalworking fluids.
Abstract:
The invention concerns a method for preparing a multiple emulsion comprising an invert emulsion consisting of an internal aqueous phase dispersed in an internal organic phase, dispersed in an external aqueous phase: the internal aqueous phase comprising optionally at least a hydrophilic active substance; the internal organic phase comprising optionally at least a hydrophobic active substance; the invert emulsion comprising at least an internal surfactant and/or at least an internal amphiphilic polymer; the external aqueous phase comprising optionally at least a hydrophilic active substance and at least an external surfactant and/or an external amphiphilic polymer.
