  • Patent number: 11180858
    Abstract: The present invention provides a gas generator, comprising a water tank and an electrolysis device. The water tank has a first hollow portion for containing electrolyzed water. The electrolysis device is disposed inside the first hollow portion of the water tank for electrolyzing the electrolyzed water to generate a hydrogen-oxygen mixed gas. When the electrolysis device starts to electrolyze the electrolyzed water, the first hollow portion of the water tank is filled with the electrolyzed water for standing at a full level of water. And after the electrolysis device electrolyzed the electrolyzed water, the level of water for the electrolyzed water filled into the first hollow portion of the water tank is higher than 95% of the full level of water. The gas generator of the present invention provides the design for saving space and nearly a zero gas chamber to reduce the possibility of explosions resulting from hydrogen-oxygen mixed gas.

    Abstract: The problem of the present invention is to provide a method or the like for producing reduced water (hydrogen-enriched water), which is effective for various diseases caused by active oxygen, more efficiently than the conventional methods, by putting metallic magnesium or the like in water. Adding a metal such as magnesium, together with a solid phase contained in an anode of an oxidation-reduction reaction, to water increases the saturating amount of magnesium ions, and improves deterioration due to magnesium hydroxide being precipitated on the surface of the metallic magnesium. Thus, the abovementioned problem is solved.

  • Publication number: 20120152755
    Abstract: The alternative cellular energy (ACE) pathway provides a non-immunological defense mechanism against infectious diseases and can also function as an effective, non-scarring, tissue repair mechanism in response to injury. The ACE pathway can be activated using energy obtained from the ultraviolet light illumination of neutral red dissolved in alcohol. The effectiveness of the alcohol used in this procedure is significantly increased by first bubbling air containing “Water Gas” (otherwise referred to as Brown's Gas or HHO) through the alcohol. The Water Gas is considered as providing an additional charge to the alcohol. Water Gas can similarly be used to charge water and other liquids and to, thereby, increase the liquid's capacity to interact with various dyes, such as neutral red, and with other enerceuticals, which are regarded as being representative of the body's ACE pigments.

  • Publication number: 20110147227
    Abstract: A method and system of separating an acid from an acid-salt solution produced in an electrochemical system using an ion exchange resin bed, by processing the acid-salt solution through the ion exchange resin bed such that the acid is retarded at the bottom of the bed and a de-acidified salt solution is recovered from the top of the bed. After removing the salt solution from the bed, the acid is recovered by back-flushing the resin bed with water.

  • Publication number: 20110027166
    Abstract: The present invention provides a process whereby pre-enrichment of water streams using a hydrogen source and a catalytic isotope exchange method at one or more remote sites to supply water with augmented deuterium concentration to a central heavy water. This central heavy water plant could be a Combined Electrolysis and Catalytic Exchange (“CECE”) heavy water production plant or a Girdler Sulfide heavy water plant. The deuterium content of water at the remote sites is increased and provides water stream(s) with augmented deuterium concentration to feed to the central heavy water production plant. This could be a first stage of the central CECE deuterium enrichment plant, increasing its capacity for heavy water production approximately in the ratio of its enrichment above natural deuterium concentrations. By relatively simple utilization of available deuterium enrichment capacity at the remote sites, advantages are achieved from a larger scale of heavy water production at the central production plant.

  • Publication number: 20100230293
    Abstract: A low-voltage, low-energy electrochemical system and method of removing protons and/or producing a base solution comprising hydroxide and carbonate/bicarbonate ions, utilizing carbon dioxide in a cathode compartment that is partitioned into a first cathode electrolyte compartment and a second cathode electrolyte compartment such that liquid flow between the cathode electrolyte compartments is possible, but wherein gaseous communication between the cathode electrolyte compartments is restricted. Carbon dioxide gas in one cathode electrolyte compartment is utilized with the cathode electrolyte in both compartments to produce the base solution with less that 3V applied across the electrodes.

  • Publication number: 20100144051
    Abstract: Method and apparatus for generating an acid or base, e.g. for chromatographic analysis of anions. For generating a base the method includes the steps of providing a cation source in a cation source reservoir, flowing an aqueous liquid stream through a base generation chamber separated from the cation source reservoir by a barrier (e.g. a charged membrane) substantially preventing liquid flow while providing a cation transport bridge, applying an electric potential between an anode cation source reservoir and a cathode in the base generation chamber to electrolytically generate hydroxide ions therein and to cause cations in the cation source reservoir to electromigrate and to be transported across the barrier toward the cathode to combine with the transported cations to form cation hydroxide, and removing the cation hydroxide in an aqueous liquid stream as an effluent from the first base generation chamber. Suitable cation sources include a salt solution, a cation hydroxide solution or cation exchange resin.

  • Publication number: 20100108536
    Abstract: An electrochemical actuator system includes a membrane electrode assembly coupled to a source of electrical energy. The membrane electrode assembly includes a proton-exchange membrane disposed between a first electrode and a second electrode. A first chamber is located on a first side of the membrane electrode assembly and is configured to hold a gas generated by applying electrical energy to the first electrode of the membrane electrode assembly. The membrane electrode assembly and the first chamber are sealed to inhibit fluid communication with the surrounding ambient environment. The chamber includes a diaphragm deformable in response to a change in an amount of the gas in the first chamber. A deformation of the diaphragm in response to the change in the amount of the gas in the first chamber causes a movement of an actuating member coupled to the diaphragm.
