  • Publication number: 20120168303
    Abstract: A salt water activated emergency lighting device has a body, an anode electrode, a cathode electrode, a water supply module, a draining module and a light board. The body has a first compartment and a second compartment with a through hole therebetween. The anode electrode is mounted in the second compartment. The cathode electrode is mounted through a periphery of the second compartment. When the mains power is down, the water supply module unblocks the through hole, and salt water in the first compartment enters the second compartment. Salt water further reacts with the anode electrode and the cathode electrode in generation of power supplied to the light board for emergency lighting. When the mains power comes back, the through hole is blocked, and the draining module pumps the salt water in the second compartment back to the first compartment. Such cycling fulfills environmental protection without consuming electrode plates unnecessarily.

  • Patent number: 8147663
    Abstract: A scaffold holding one or more ion-conductive ceramic membranes for use in an electrochemical cell is described. Generally, the scaffold includes a thermoplastic plate defining one or more orifices. Each orifice is typically defined by a first, second, and third aperture, wherein the second aperture is disposed between the first and third apertures. The diameter of the second aperture can be larger than the diameters of the first and third apertures. While at an operating temperature the diameter of the ceramic membrane is larger than the diameters of the first and third apertures, heating the scaffold to a sufficient temperature and for a sufficient time causes the third aperture's diameter to become larger than the membrane's diameter. Thus, heating the scaffold may allow the membrane to be inserted into the orifice. Cooling the scaffold can then cause the third aperture's diameter to shrink and trap the membrane within the orifice.

    Abstract: Disclosed is a unit for producing sterilized water. The unit comprises an electrode module, a pair of electrode rods and a frame. The electrode module includes a pair of electrode plates and a hollow electrode separator positioned between the electrode plates to separate the electrode plates from each other. Each of the electrode plates has a plurality of elongated slots formed therein. The electrode rods apply different voltages to the respective electrode plates. The frame is positioned at one side of the electrode module and has portions for receiving the respective electrode rods. Each of the electrode plates has a pair of holes formed at the circumference thereof. The electrode rods penetrate through the respective holes. The holes have different sizes. The electrode plates are stacked in such a manner that the holes having different sizes overlap each other. This stack enables the application of different voltages to the electrode plates through the respective electrode rods.

  • Patent number: 7736475
    Abstract: The present invention relates, generally, to a method for electrowinning copper powder, and more particularly to a method for electrowinning copper powder from a copper-containing solution using the ferrous/ferric anode reaction. In accordance with various embodiments of the present invention, a process for producing copper powder by electrowinning employs alternative anode reaction technology, namely, the ferrous/ferric anode reaction, and enables the efficient and cost-effective production of copper powder at a total cell voltage of less than about 1.5 V and at current densities of greater than 50 A/ft2. A copper powder electrowinning process in accordance with the present invention also reduces or eliminates acid mist generation that is characteristic of electrowinning operations utilizing conventional electrowinning chemistry (e.g., oxygen evolution at the anode), which is advantageous.
