摘要： An anode for cathodically-protected steel-reinforced concrete is embedded in an ion-conductive overlay on the concrete structure. The anode comprises at least one sheet of highly expanded valve metal mesh having a pattern of voids defined by a network of valve metal strands connected at a multiplicity of nodes. This provides a redundancy of current-carrying paths through the mesh which ensures effective current distribution throughout the mesh even in the event of possible breakage of a number of individual strands. The surface of the valve metal mesh carries an electrochemically active coating. At least one current distribution member is welded to the valve metal mesh. The entire area of the structure to be protected, excluding non-protected openings for obstacles and the like, is covered by a single piece of the mesh, or several pieces in close proximity with one another.

摘要： A continuous length anode is formed of relatively small valve metal wire having a electrocatalytic coating braided into a highly flexible ribbon. The wire may be copper cored. The valve metal is preferably titanium, although tantalum or niobium are also preferred. The coating is preferably a mixed metal oxide coating. The braid is formed from wire sizes of from about 1/16 or less to about 1/8" in diameter and the braided ribbon may be about 0.1 to about 6" inches wide. Four system applications are disclosed, two for steel reinforced concrete, one for a tank bottom, and one for a buried pipe. The braided anode may be used in combination with valve metal ribbon or bar and may readily be electrically connected to power feeds or to itself by spot weld or crimp connections. Power feeds may be connected at a butt end or anywhere along the length of the braid.

摘要： A system provides impressed current cathodic protection (ICCP) of a marine structure (50) and powers a load in a load arrangement (100) arranged on the marine structure (50) and in contact with the water (10). The power source provides a supply current to generate an electrical potential of the marine structure. The load arrangement (100) has an electrode arranged (130) to extend from the load arrangement into the water for transferring the supply current via the water. The load (20) is coupled between the electrode (130) and a power node (120). The power source is connected to the marine structure and to the power node. The load arrangement is arranged to use the supply current to provide power to the load. Thereto the supply voltage may have an AC component at a high frequency. The load may be an UV-C LED for emitting anti-fouling light.

摘要： An illustrated view of an improved anode rod assembly for removing corrosive elements from the water of the tank. The improved anode rod assembly is useful for providing a longer life span for water heater units. Further, an illustrated view of an exemplary water intake assembly is presented. The water intake assembly is useful, it provides an extra port so that more anodes can be inserted into the tank. Also having the dip tube at the very bottom of the tank provides more hot water and increases the efficiency of the water heater. Having multiple anodes will give an indefinite life span for the water heater.
