  • Liquid dispensing method for manufacturing an electrowetting device
    Patent number: 9625704
    Abstract: A method of manufacturing an electrowetting device includes dispensing a first liquid on a surface of a support plate and dispensing a second liquid to adjoin the first liquid. The first liquid is an emulsion. A first portion of the first liquid transfers into the second liquid to form a first layer of liquid and a second layer of liquid substantially immiscible with the first layer. The first layer comprises a second portion of the first liquid and the second layer comprises the second liquid and the first portion.

  • Determination of vitamin D metabolite and displacement from plasma or serum binding proteins
    Patent number: 7482162
    Abstract: We disclose methods for measuring vitamin D metabolite in plasma or serum samples. The methods comprise a step of adding to the plasma or serum samples a non-competitive displacement agent comprising 8-anilino-1-naphthalenesulfonic acid ammonium salt, 3-(acetonylbenzyl)-4-hydroxycoumarin and a water miscible solvent. The non-competitive displacement agent separates vitamin D metabolite from binding proteins in the sample, such that the displaced vitamin D metabolite is available for capture and detection in subsequent binding assays. Thus, our invention finds use in methods of separating and detecting vitamin D metabolites otherwise tightly bound to plasma or serum binding proteins.

  • Method for separating fluids
    Patent number: 6989103
    Abstract: Methods of treatment of fluids produced by an oil or gas well following a stimulation operation, allowing separation from the fluids and re-injection of oil and gas hydrocarbons in a production pipeline under pressure, and allowing achievement of suitable quality for the residual fluids compatible with their rejection, for example into the sea, including the following three elements; neutralization of the fluids by mixing with a high pH chemical, until the resulting pH reaches a level compatible with the equipment and pipes; use of optimized emulsion breakers in a phase separator, selected for best results with the fluids produced by the well, to accelerate the separation of oil from the fluids, and to lower the residual oil content in the fluids to levels compatible with environmental regulations; and use of a multi-phase pump to pump the oil and gas hydrocarbons produced and reinject them in a pipeline under pressure.

  • Method of recycling water contaminated oil based drilling fluid
    Patent number: 6977048
    Abstract: A method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oil component and an aqueous component. The method includes: mixing the invert emulsion drilling fluid with a emulsion clearing agent, wherein the emulsion clearing agent is a mixture of an anionic tensid and a non-ionic tensid; and separating the oil component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaking agent that is a combination of an anionic tensid, a non-ionic tensid and an alkyl polyglycoside tensid.

  • Method for recycling of oil based drilling fluid contaminated with water and water contaminated with oil based drilling fluid
    Patent number: 6881349
    Abstract: A mobile apparatus and method for recycling an invert emulsion based drilling fluid, in which the invert emulsion based drilling fluid includes an oleaginous component and an aqueous component. The apparatus includes an emulsion breaking tank, a water treatment tank, a filter press, and hydrocarbon filters. The method includes: mixing said invert emulsion drilling fluid with a emulsion breaker, wherein the emulsion breaker is a mixture of an alkyl glucoside and an alkane sulfonate; and separating the oleaginous component of the invert emulsion drilling fluid from the aqueous component of the invert emulsion drilling fluid. The method preferably utilizes an emulsion breaker that is a combination of an anionic surfactant, a nonionic surfactant and an alkyl polyglycoside surfactant.
