  • Patent number: 9550247
    Abstract: A cathodic protection device enclosing a reference cell and a conductive media and having two coupon assemblies mounted, facing opposing direction, on an exterior surface. The coupon assemblies each have a disc-shaped coupon seated in a coupon jacket and are electrically coupled to a wire. The coupon jacket defines a pocket in a first surface and a groove in a second, opposing surface thereof. The disc-shaped coupon is seated in the pocket and the wire is seated in the groove with the electrical junction therebetween aligned with an aperture connecting the pocket to the groove. A sealing material is used to form a watertight seal between the disc-shaped coupon and the pocket and fills the groove. The device includes a hydrophilic porous member having a first surface in communication with the conductive media and a second surface in communication with an external environment.

  • Patent number: 9534305
    Abstract: Disclosed are electrolysis catalysts formed from cobalt, oxygen and buffering electrolytes (e.g. fluoride). They can be formed as a coating on an anode by conducting an electrolysis reaction using an electrolyte containing cobalt and an anionic buffering electrolyte. The catalysts will facilitate the conversion of water to oxygen and hydrogen gas at a range of mildly acidic conditions. Alternatively, these anodes can be used with cathodes that facilitate other desirable reactions such as converting carbon dioxide to methanol.

  • Patent number: 9499915
    Abstract: Embodiments of a system and method for providing cathodic protection to a vessel include encapsulating a dimensionally stable anode with a wax-repellant cementitious coating. The anode, with the encapsulant, is inserted into a structure to be protected, such as a vessel for handling wet crude. A power supply is connected to the anode and to the vessel, making the vessel a cathode. When power is applied, ions flow from the anode, through the encapsulant and fluids in the vessel, to the vessel structure. The encapsulant prevents paraffin wax from building up on the anode.

  • Patent number: 9441307
    Abstract: Embodiments of systems and methods for providing cathodic protection to a fluid-containing vessel include measuring two distinct voltages at a junction box exterior to the fluid-containing vessel. The first voltage is measured across a shunt in the junction box such that a current magnitude through the shunt can be determined using Ohm's Law that is representative of a current output of one or more sacrificial anodes disposed within the fluid-containing vessel. The second voltage is measured by depressing a pushbutton of a momentary switch to open the switch and interrupt current flow through the shunt. The second voltage is representative of a voltage difference between the one or more sacrificial anodes and the a wall of the fluid-containing vessel.

  • Patent number: 9428301
    Abstract: A self-destructive aquatic device for use in a water environment is formed with a body having a metallic portion and a covering preventing exposure of the metallic portion of the body from the water environment. A gap in the covering is used to expose the metallic portion of the body to the water environment. The covering has a cathodic property with respect to the metallic portion of the body, so that the gap and the covering establishing a cathodic-anodic ratio of areas exposed to the water environment to promote erosion of the metallic portion of the body in the water environment. This, in turn, results in controlled break-up of the aquatic device.

  • Patent number: 9382631
    Abstract: This invention is a device that provides a multi use cathodic protection system for steel and reinforced concrete and method of use that will permit a user to more easily and accurately place an impressed current cathodic protection system, a sacrificial or galvanic anode cathodic protection system, or combination thereof around a reinforced structure to be protected and thereafter fill with concrete by use of a uniquely engineered fiberglass reinforced plastic form. This invention once put in place around the structure being protected can more easily be filled with concrete without having the attached titanium mesh or zinc anode mesh bend or move outside of the effective proximity from the protected structure. The fiberglass reinforced plastic form has a corrugated or roughed surface that provides an increased surface area to bind or grip the fiberglass reinforced plastic form to the poured concrete once cured.
