  • Patent number: 9757775
    Abstract: Elemental fluorine is often manufactured electrochemically from a solution of KF in hydrogen fluoride and contains varying amounts of HF as impurity. The present invention provides a method for chamber cleaning using F2 which contains more than 0.1% by weight and equal to or less than 10% by weight of HF. Surprisingly, such an F2 is very well suited for the purpose of chamber cleaning. In a preferred embodiment, the F2 which contains more than 0.1% by weight and less than 2.5% by weight of HF is electrolytically produced, cleaned, delivered and used on site, without any pressurizing treatment. Omitting cleaning steps and process and using process conditions leaving a relatively high HF content in the F2 allows at the same time to omit pressurizing steps. The advantage is that less cleaning steps.

  • Publication number: 20130068627
    Abstract: A control device receives an output signal from a liquid level sensor disposed in an anode chamber. This output signal indicates whether the liquid level of the electrolytic bath in the anode chamber is higher than a reference level. When the liquid level of the electrolytic bath in the anode chamber is higher than the reference level, the control device increases, by a prescribe value, the frequency of a compressor driving voltage that is generated in an inverter circuit. This increases the rotational speed of a motor in the compressor, increases the discharge pressure of hydrogen gas being discharged from the compressor, and decreases the pressure inside the cathode chamber. As a result, the liquid level of the electrolytic bath in the cathode chamber rises, and the liquid level of the electrolytic bath in the anode chamber falls below the reference level.

  • Patent number: 6699712
    Abstract: A shocking chamber for performing electroporation is constructed in the form of a base and a hinged lid which when lowered forms an enclosure with the base that fully encloses a cuvette and impresses a high voltage across the cuvette, the voltage connection becoming disengaged upon the simple raising of the lid. The base contains two pairs of electrical leads, one pair engaging the cuvette with spring-loaded contacts that provide electrical connections to the cuvette while helping to secure the cuvette in place, and the other pair joined to high-voltage terminals. A shunt built into the lid bridges the two pairs of leads in the base when the lid is closed and pivots out of the way to clear all leads when the lid is opened. These and other features of the construction provide the user with a safe and secure means of forming the high-voltage electrical connections used in electroporation in an apparatus that can be operated with one hand.

  • Publication number: 20030230495
    Abstract: One embodiment of a method of operating an electrochemical cell system comprises: flowing supply water to an anode electrode of an electrolysis cell, applying a first current density to the electrolysis cell, electrolyzing the supply water at the anode electrode wherein hydrogen ions and a first portion water migrate to a cathode electrode of the electrolysis cell, collecting the first portion of water in a chamber in fluid communication with the cathode electrode, monitoring a first portion water level in the chamber, when the first portion water level attains a first selected level, decreasing the supply water flow to the anode electrode a sufficient amount to draw the first portion water from the chamber to the anode electrode, and electrolyzing the first portion water.

  • Patent number: 6319390
    Abstract: A method of and system for cleansing a toilet or urinal are proposed which require less maintenance work and are safer to users than conventional methods using acid substances, and which can prevent the formation of stain on the toilet or urinal effectively and suppress the generation of ammonia sufficiently, thus accomplishing a sufficient countermeasure to the stench. A urinal (A1) is provided with a continuous electrolytic cell (1) having at least a pair of electrodes, a passage formed between the electrodes, and an inlet and an outlet that lead to the passage. Tap water is electrolyzed by the continuous electrolytic cell (1), whereby free chlorine is produced. Then the water containing free chlorine produced is supplied to the urinal (A1), and the water containing free chlorine sterilizes the inside of the urinal, thus preventing urease, an enzyme carried by bacteria, from acting to decompose urea.

    Abstract: A machining solution for removal-machining an object to be machined 103 is introduced to an inside of a machining solution container 101, and a predetermined voltage is applied to between the machining electrode 104 and the object to be machined 103 to cause electrochemical reaction thereby fabricating a part cast mold. Then the machining solution is changed to a machining solution for metal layer formation to effect additional machining on a surface of the cast mold, forming a metal layer. Then the machining solution is changed to a machining solution for part formation to effect additional machining inside the cast mold, forming a part. Finally the machining solution is changed to a machining solution for dissolving metal layer to dissolve the metal layer to taking out the inside part, fabricating a part.
