Abstract: A surface active compound is supplied into contact with an oilfield production fluid that comprises a mixture of water and oil including water soluble organics. The surface active compound comprises at least one alkoxylate chain and at least one end group attached to each of the at least one alkoxylate chain. The surface active compound is supplied into the oilfield production fluid at a dosage rate that is effective to self-associate at interfaces between the water and oil and inhibit the water soluble organics in the oil from entering the water when the oilfield production fluid is depressurized.

Abstract: The invention discloses synergistic combinations of surfactants blends and cleaning composition. In certain embodiments a surfactant system is disclosed which includes extended anionic surfactants, linker surfactants, and a multiply charged cation component. This system forms emulsions with, and can remove greasy and oily stains, even those comprised of non-trans fats. The compositions may be used alone, as a pre-spotter or other pre-treatment or as a part of a soft surface or hard surface cleaning composition.

Abstract: The invention is a disposable cover handle cover for a surgical light head, and more particularly to a single-piece, integrally-formed disposable handle cover for a surgical light head and the like. The disposable cover includes a single-piece hollow member having a first open end adapted to receive the positioning handle of the surgical light head housing a camera and a second open end generally opposite the first end. The second end is closed off by a lens disposed within and integral with the hollow body.

Abstract: Disclosed herein are systems and methods for automated real-time monitoring and controlling desalting in a crude distillation unit. Crude oil and wash water are mixed by a pressure drop across a mix valve, thereby forming a crude oil/water phase stream. The crude oil/water phase stream is supplied into a desalter vessel, whereupon an emulsion forms at an interface between the crude oil and the water phase. The crude oil/water phase stream is contacted with a dosage of an emulsion breaker in an applied electric field. At least one property associated with the emulsion is measured using an emulsion level indicator. A total chlorine and a water percentage of the crude oil are measured. At least one of the pressure drop and the dosage of the emulsion breaker is adjusted substantially in real time in response to at least one of the measured properties, total chlorine, and water percentage.

Abstract: A dryer monitoring system receives dryer information from one or more sensors concerning operation of one or more dryers, such as clothes dryers. For example, the dryer monitoring system may receive temperature, humidity, and/or dryer on/off information concerning the dryers. The dryer monitoring system may analyze the dryer information and generate reports communicating the dryer information, identify possible maintenance issues with the dryers, identify ambient environmental conditions that may lead to inefficient drying, identify possible operator errors, and/or diagnose other dryer conditions that may be determined based on the dryer information.

Abstract: The invention provides a method and apparatus for continuously feeding wet gel polymers into a drying step of a dry polymer synthesis operation. A number of pistons are arranged having inner chambers through which monomers and other reagents are fed and polymerized into wet gel polymers. Each piston operates according to a coordinated schedule so that as one piston finishes extruding polymer into the drying step, a second piston has completed polymerizing more polymer and continues to feed more polymer without interruption. The then finished is re-fed more reagents so as to be ready again when needed next. As a result, cost effective continuous feeding can be achieved without the contamination and impurity problems that have plagued previous attempts to accomplish this.
Abstract: Synergistic combinations of extended chain surfactants and co-surfactants, emulsions or microemulsions and cleaning compositions incorporating the same are provided. In certain embodiments a surfactant system is disclosed which includes extended nonionic surfactants, and a linker surfactant. This system forms stable emulsions or microemulsions with oils, including non-trans fats and fatty acids and these emulsions or microemulsions are stable, irreversible and can be created at low temperature. The cleaning compositions may include the surfactant system alone, a stable emulsion or microemulsion with oil and the surfactant system, a pre-spotter or other pre-treatment or soft surface and hard surface cleaning compositions comprising the surfactant combination.

Abstract: The present invention relates to high alkaline-solvent cleaners, cleaning systems and methods for removing polymerized zero trans fat soils. The high alkaline-solvent cleaner of the present invention generally includes one or more soil wetting and cleaning solvent(s) and one or more alkaline wetting and saponifying agent(s) that wets and saponifies the soil. In various embodiments, the cleaners may include, at least one cleaning agent comprising a surfactant or surfactant system and/or a at least one chelating/sequestering/threshold agent. In some embodiments, the cleaners may include one or more components to modify the composition form and/or the application method. All components described above can also be optimized optionally, to provide emulsification of a composition (both as a usable product or a concentrate that can be diluted to form a usable product).
Abstract: Stability enhancement agents for use in a solidification matrices and solid detergent compositions are described.

Abstract: The passage of a container along a conveyor is lubricated by applying to the container or conveyor a mixture of a water-miscible silicone material and a water-miscible lubricant. The mixture can be applied in relatively low amounts, to provide thin, substantially non-dripping lubricating films. In contrast to dilute aqueous lubricants, the lubricants of the invention provide drier lubrication of the conveyors and containers, a cleaner conveyor line and reduced lubricant usage, thereby reducing waste, cleanup and disposal problems.
