  • Patent number: 10435315
    Abstract: An electrolyzed water processor chamber with an anodic chamber having an anode plate held in an anode tray, and a cathodic chamber having a cathode plate held within a cathode tray. The plates are charged by an electrical current, to separate an incoming water stream into its electromagnetically ionized alkaline and acidic components, across an ion exchange membrane sandwiched between the anode and cathode plate trays. The trays can include sets of ducts and cavities, so that when the trays are stacked together, with the cavities aligning to form plenums for the routing of water between the trays. The trays stack as modular units, so that any multiple of the anodic and cathodic tray pairs, with their plates and sandwiched membrane, can be stacked together and function as a combined processor chamber, with end caps mounted on the top-most and bottom-most plate trays.

  • Patent number: 10428430
    Abstract: An improved marine anode sled comprises a single piece casting with high surface to weight ratio providing increased active surfaces and improved reliability. In one embodiment the anode weighs about 2,000 lbs and has an active surface area of about 5,000 square inches and a current output capacity of up to 160 amps. The improved anode has considerably higher current output than existing anode sleds with similar weight. Unlike known anode sleds, the entire exposed surface of new anode sled is anode material and passes current to a surrounding medium. The single piece casting eliminates structural failure when a frame of know anode sleds is damaged, and electrical failure when cables connecting multiple anodes are damaged. Two redundant lead cable are attached proximal to opposite corners to optimize reliability and electrical performance.

  • Patent number: 10422045
    Abstract: An improved steel plate alkali electrolyzer uses an anode steel plate, by-polar steel plates, and a cathode steel plate (the number of bi-polar plated is determined by the voltage applied, the formula explained in Claim). The steel plate edges are wrapped with an insulating material to hold them in precise alignment. This unit is housed in a containment vessel, with the anode and cathode steel plates extending past the outside of the containment vessel to make electrical connections outside of liquid filled vessel. Shape and arrangement of the plates enables the gas production to create a circulating electrolyte (without the use of a pump) that produces a cooler operating and more efficient production of Brown's gas per watt, and less expensive to construction than any other known electrolyzer. Design is scalable allowing for a wide range of gas production and applications.

  • Patent number: 10364506
    Abstract: An electro-processing apparatus has a contact ring including a seal which is able to compensate for electric field distortions created by a notch (or other irregularity) on the wafer or work piece. The shape of the contact ring at the notch is changed, to reduce current crowding at the notch. The change in shape changes the resistance of the current path between a thief electrode and the wafer edge to increase thief electrode current drawn from the region of the notch. As a result, the wafer is plated with a film having more uniform thickness.
