20160122686 | DEVICE AND METHOD FOR SOLUBILIZING, SEPARATING, REMOVING AND REACTING CARBOXYLIC ACIDS IN OILS, FATS, AQUEOUS OR ORGANIC SOLUTIONS BY MEANS OF MICRO-OR NANOEMULSIFICATION - The present invention is directed to solubilizing compounds, a device and a method for solubilizing and removing carboxylic acids and especially fatty acids from oils, fats, aqueous emulsion, aqueous media and organic solutions. Devices utilizing the inventive method shall be used for separating carboxylic acids from oils, fats, aqueous emulsion, lipophilic media or organic solutions, respectively by preparing an aqueous micro- or nanoemulsion of the carboxylic acids especially the fatty acids and the solubilizing compound which contains at least one amidino and/or gianidino group. Solubilization effects of solubilizing compounds combined with the inventive use of separation methods for carboxylic acids can be used to treat persons in need of removal of fatty acids or analyze carboxylic acids from blood or process other solutions in food, pharmacy, chemistry, bio fuel industry or other industrial processings. | 05-05-2016 |

20110049032 | DEVICE FOR DISSOLVING OXYGEN INTO WATER AND APPARATUS FOR MAKING SUPEROXYGENATED WATER EMPLOYING THE SAME - An apparatus for making oxygenated water capable of producing super oxygenated water and retaining the dissolved oxygen for long time periods, while being applicable to an open reservoir as well as a closed reservoir and having simple structure so as to be implemented in small as well as large size machines. According to an aspect of the present invention, the oxygenating apparatus circulates water contained in a water reservoir and dissolves oxygen from an oxygen source into the circulated water flow. A pump is coupled to the outlet of the water reservoir in fluid communication, and circulates the water contained in the water reservoir. An oxygen dissolving device has an inlet coupled to the pump in fluid communication and an outlet coupled to the water reservoir in fluid communication, and dissolves oxygen from the oxygen source to water supplied by the pump. A plurality of trays are installed in cascade vertically in a housing of the oxygen dissolving device. A water supply tip is coupled to the inlet in fluid communication and provides the water supplied by the pump to a highest tray of the plurality of trays. Pressure maintaining means is coupled to the outlet in fluid communication and maintains internal pressure of the housing in a predetermined range while allowing oxygenated water to return from the outlet to the water reservoir. | 03-03-2011 |
