  • Patent number: 10761079
    Abstract: The present invention is directed to a method of estimating an overheating temperature of an oil-immersed electric appliance in which ester oil is used as insulating oil. The overheating temperature is estimated based on a first concentration ratio representing a concentration ratio between two types of gas components contained in the ester oil and a second concentration ratio representing a concentration ratio between other two types of gas components contained in the ester oil. The first concentration ratio and the second concentration ratio are selected from a concentration ratio between acetylene and ethane, a concentration ratio between acetylene and hydrogen, a concentration ratio between acetylene and methane, and a concentration ratio between acetylene and ethylene.

  • Patent number: 10344250
    Abstract: A liquid composition according to one embodiment of the present invention contains 0.0001 mol % to 40 mol % (Z)-1,2-dichloro-3,3,3-trifluoropropene (1223Z) and 99.9999 mol % to 60 mol % (E)-1,2-dichloro-ethylene (t-DCE). The liquid composition has less influence on the global environment and azeotropic (or azeotrope-like) properties. There occurs practically no composition change even when the liquid composition is used in an open system or used for a long term. Further, it is less likely that there will occur a composition change even when the liquid composition is recovered by distillation. The liquid composition is thus suitably usable as a cleaning agent (solvent). In particular, the liquid composition of 90 mol % or less of t-DCE is classified as non-hazardous under the Fire Serves Act.

    Abstract: An active cancellation system may provide a first and second transmission gates that are fed with an input signal and a complimentary signal, respectively. The first transmission gate may be switched on/off, and a second transmission gate may remain off at all times. When switched off, the first transmission gate may provide a leakage signal resulting from leakage in current, especially at high input frequencies, which is detrimental to performance. The complimentary signal fed to the second transmission gate is out of phase with the input signal, but identical in amplitude. Thus, second transmission gate may output a signal that can cancel out the leakage signal from the first transmission gate.

  • Patent number: 8110112
    Abstract: A rapid one-pass liquid filtration system efficiently concentrates biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. Additional concentration stages may be added in “cascade” fashion, in order to concentrate particles below the size cut of each preceding stage remaining in the separated fluid in a concentrated sample suspension. This process can also be used to create a “band-pass” concentration for concentration of a particular target size particle within a narrow range.

  • Publication number: 20080308126
    Abstract: An installation for washing hand trucks of operating machines, particularly of rotogravure machines, is constructed and designed in order to receive and to treat in a wash chamber a whole hand truck along with all its parts, not dismounted. In the wash chamber of the installation there is a number of tubular bored bars which receive the wash solvent from a circulation pump and direct the same in the form of jets against the parts of the treated hand truck which require to be washed. The bars form a rotatable whole, are displaced in rotation and in translation in an alternate movement by pneumatic cylinders, and advantageously they surround a print cylinder mounted in the hand truck. A lower collecting basin receives the falling used solvent, and therefrom the solvent is sucked by the circulation pump during a first pre-wash step.

  • Patent number: 7389654
    Abstract: Gases are vented from a waste site such as a landfill, and the gases are separated into at least three streams comprising a hydrocarbon stream, a carbon dioxide stream, and residue stream. At least a portion of the carbon dioxide stream and hydrocarbon stream are liquefied or converted to a supercritical liquid. At least some of the carbon dioxide gas stream (as a liquid or supercritical fluid) is used in a cleaning step, preferably a polymer cleaning step, and more preferably a polymer cleaning step in a polymer recycling process, and most preferably in a polymer cleaning step in a polymer recycling system where the cleaning is performed on-site at the waste site.

  • Publication number: 20080115800
    Abstract: A method for treating catalysts, in particular, for the cleaning and/or regeneration of a catalyst, whereby the catalyst comprises parallel channels. The catalyst is taken out of service for treatment and flushed with a cleaning and/or regeneration fluid in-situ in the assembled state. The cleaning and/or regeneration fluid is introduced under pressure to that end of a bundle of adjacent channels away from the pressurized end of the catalyst. The channels of the bundle are flushed against gravity and the cleaning and/or regeneration fluid escapes from the other end of the channels thereupon enters the free ends of other adjacent channels and flows through the same under the effect of gravity.

  • Patent number: 7329321
    Abstract: A method for removing post-processing residues in a single wafer cleaning system is provided. The method initiates with providing a first heated fluid to a proximity head disposed over a substrate. Then, a meniscus of the first fluid is generated between a surface of the substrate and an opposing surface of the proximity head. The substrate is linearly moved under the proximity head. A single wafer cleaning system is also provided.

  • Patent number: 7287933
    Abstract: An improved process is described for the removal of organic pollutants from soil by extraction with a lipophylic solvent, wherein the improvement consists in the fact that the purified soil is treated with water to remove the residual solvent. This process allows the residual solvent to be completely removed from the purified soil enabling it to be re-inserted into the environment, with a low energy consumption and a greater guarante of safety in the running of the plant.

  • Patent number: 7282099
    Abstract: Method for processing an article by contacting the article with a dense fluid. The article is introduced into a sealable processing chamber and the processing chamber is sealed. A dense fluid is prepared by introducing a subcritical fluid into a pressurization vessel and isolating the vessel, and then heating the subcritical fluid at essentially constant volume and essentially constant density to yield a dense fluid. At least a portion of the dense fluid is transferred from the pressurization vessel to the processing chamber, wherein the transfer of the dense fluid is driven by the difference between the pressure in the pressurization vessel and the pressure in the processing chamber, thereby pressurizing the processing chamber with transferred dense fluid. The article is contacted with the transferred dense fluid to yield a spent dense fluid and a treated article, and the spent dense fluid is separated from the treated article.
