  • Patent number: 9447540
    Abstract: The present invention relates to a process for dewatering a slurry comprising microfibrillated cellulose wherein the process comprises the following steps of, providing a slurry comprising microfibrillated cellulose and liquid, subjecting the slurry to an electric field inducing the liquid of the slurry to flow and separating the liquid from the microfibrillated cellulose. The invention also relates to microfibrillated cellulose dewatered according to the process.

  • Patent number: 9447541
    Abstract: The present invention relates to a process for purifying a slurry comprising cellulose, such as microfibrillated cellulose, wherein the process comprises the following steps: —providing a slurry comprising cellulose and liquid, —subjecting the slurry to an electric field inducing the liquid of the slurry to flow, —separating the liquid from the cellulose thus obtaining a liquid depleted slurry, —adding a washing liquid, such as an organic solvent, to the liquid depleted slurry—subjecting the liquid depleted slurry to an electric field inducing the washing liquid of the slurry to flow and—separating the washing liquid from the cellulose, thus obtaining a purified cellulose. The invention also relates to cellulose such as microfibrillated cellulose obtainable from said process.

  • Patent number: 7491193
    Abstract: A personal care apparatus (1) is provided with a suction nozzle configuration (4) which has two different suction nozzles (15, 22) with two different suction sections (27, 26), wherein the suction nozzles (15, 22) are held adjustably in relation to each other along a path of motion (16) which is preferably perpendicularly to their suction sections (27, 26), so that by means of an adjustment of this type in each case one of the suction nozzles (15, 22) may be adjusted with its suction section (27, 26) into an operating position permitting suctorial interaction with an area of the skin.

  • Patent number: 6877251
    Abstract: A drying apparatus for a sheet-fed offset printing machine which dries sheets as they pass along a sheet path with forcefully directed air and/or heat. The drying apparatus of the present invention is adapted for more effective sheet drying by means of an electrode and a corresponding counter electrode, wherein the electrode is connected to a high-voltage source and a high voltage is applied to the electrode by the high-voltage source in dependence on the operation of the sheet-fed printing machine and/or the length of the sheets.

  • Publication number: 20020083957
    Abstract: A method and system for in-situ cleaning of a reticle. Ionized gas is directed onto the reticle by a delivery device. The ionized gas neutralizes electro-static attraction between the reticle and particulate contaminants on the reticle and thereby dislodges them from the reticle. The ionized gas and particulate contaminants are then removed from the reticle by a vacuuming pump and transported from the system by a contaminant collector. As a result of the in-situ cleaning method and system, the overall risk of chip defects due to reticle particulate contaminants is reduced, and chip and wafer yield is improved.
