Abstract: An improved sacrificial galvanic anode assembly for cathodic protection of a steel reinforced concrete structure. A galvanic cathodic protection device uses an embedded sacrificial anode of metallic foam for increased reactive surface area covered with a flexible penetrating coating to provide a continuous electrolyte to keep it active. The formulated coating paste is inert to cement embedment material and is pre-applied on the anode body prior to encapsulation. An integrated conductive contact band extends from the coated anode to attachment to a reinforcement bar for establishing electrical conductively therewith within the concrete structure transferring galvanic corrosion to the anode.

Abstract: An improved sacrificial galvanic anode assembly for cathodic protection of a steel reinforced concrete structure. A galvanic cathodic protection device uses a multi-layered embedded sacrificial anode such as zinc covered with a flexible layer of paste to provide a continuous electrolyte to keep it active. The formulated paste is inert to cement embedment material and is pre-coated on the anode body prior to encapsulation. An integrated conductive contact band extends from within the coated anode to attachment to a reinforcement bar for establishing electrical conductively therewith in the concrete structure transferring galvanic corrosion to the anode.

Abstract: Galvanic protection of a reinforced concrete structure or a metallic structure immersed or partially immersed in water or seawater utilizes a sacrificial anode having a more negative electrode potential than that of the metal to be protected but connected to the reinforcement or metallic structure, and the anode immersed in electrolyte solution creating an corrosive environment for the anode. The electrolyte solution must exist for internal charge transfer by ionic conductance, and to complete the electric circuit of the galvanic cell therefore both the metal or reinforced structure and the sacrificial anode have to be immersed in an electrolyte solution. The anode will provide in that way sufficient current to protect the reinforcement or metal structure against corrosion. The present invention resides in a method where the sacrificial anode immersed in an electrolyte solution can be positioned on a remote location e.g. in a small container away from the reinforced concrete or metal structure.

Abstract: A booster (34) for a wind turbine (12) of the type containing an impeller (14) having a plurality of radial curved vanes (16) mounted on a shaft (18) connected to an electric generator (20). The booster (34) comprises a structure (36) mounted in a stationary manner about the impeller (14) for increasing rotation speed of the radial curved vanes (16) on the shaft (18) and operate more efficiently the electric generator (20), to put out more electrical energy therefrom.
