Abstract: The present invention relates to an improved method for solubilizing an oil-soluble pigment efficiently in an oil or fat by extraction of a solid preparation containing the oil-soluble pigment, where the extraction takes place in the presence of water, an edible oil or fat and a nonionic surfactant. It also relates to the composition prepared by the extraction, and the use of this composition in animal feed to produce feed pellets. The combination of water and nonionic surfactant increases the amount of pigment that is extracted and solubilized.
Abstract: The present invention relates to a process for manufacturing an electrode comprising depositing on an electrode substrate a binder dispersion comprising a precursor of a conductive or semiconductive oxide, forming a conductive or semiconductive oxide coating from the precursor on the electrode substrate, depositing an electroconductive titanium oxide and electrode particles on the conductive or semiconductive oxide coating, adhering the electroconductive titanium oxide and the electrode particles to the formed conductive or semiconductive oxide coating. The invention also relates to an electrode obtainable by the process, and the use thereof in an electrolytic cell.
Abstract: The invention relates to novel cellulose derivatives comprising a ligand capable of forming a complex with a polyvalent metal ion. The invention further pertains to a process of preparing such cellulose derivatives.
Abstract: Described are coccidia strains and microbiological cultures comprising such strains. The coccidia strains are selected for tolerance to one group of coccidiostatic drugs, sensitivity to a second group of coccidiostatic drugs, and decreased proliferative capacity. Also described are compositions and vaccines based on such coccidia strain.

Abstract: A process for forming a coating on a substrate, including the steps of effecting tribostatic charging of a body of powder by establishing a fluidised-bed of the body of powder in a fluidising chamber at least a part of which is conductive, applying a voltage to the conductive part of the fluidising chamber, immersing a substrate which is electrically non-conductive or poorly conductive, either electrically isolated or earthed, wholly or partly in the fluidised bed, withdrawing the substrate from the fluidised-bed and forming adherent particles of the powder into a continuous coating over at least part of the substrate.
Abstract: The invention relates to thermally expandable thermoplastic microspheres comprising a polymer shell made from ethylenically unsaturated monomers encapsulating a propellant, said ethylenically unsaturated monomers comprising from 20 to 80 wt % of acrylonitrile, from 20 to 80 wt % of monomers selected from the group consisting of esters of acrylic acid, from 0 to 10 wt % of methacrylonitrile, from 0 to 40 wt % of monomers selected from the group consisting of esters of methacrylic acid, the total amount of acrylonitrile and esters of acrylic acid constituting from 50 to 100 wt % of said ethylenically unsaturated monomers, and said propellant comprising at least one of methane, ethane, propane, isobutane, n-butane and isopentane. The invention further relates to the production and use of the microspheres.
