It consists of connecting the steel (6) to a discrete sacrificial anode assembly (7) comprising a base metal (1), a relatively small quantity of catalytic activating agent in contact with the base metal and a substantially inert porous layer (3) that surrounds the base metal and catalytic activating agent. The inert porous layer efficiently maintains a sustainable concentration gradient of the catalytic activating agent between the base metal and the surrounding environment as a result of the electric field across this layer. The preferred porous layer comprises a material that exhibits a net repulsion of negative ions from its pore system and the preferred catalytic activating agent comprises doubly charged sulphate ions as small electric fields maintain very high concentration gradients of these ions resulting in high concentrations at the base metal surface and insignificant concentrations at the assembly periphery.Type: GrantFiled: October 17, 2005Date of Patent: July 6, 2010Inventors: Gareth Glass, Adrian Roberts

Publication number: 20090241336Abstract: An apparatus and method for making cored wire filled with a powdery and/or granular fill material are disclosed. The present invention controls automatically the depositing of fill material used in cored wire manufacturing by accounting for a variety of process changes, such as, for example, variations in strip width, strip thickness, fill material flow, and fill material density. Such automatic monitoring and control uses detected strip measurements and detected fill material volumes to produce a high quality tubular welding wire (e.g., about±0.5% variation from a desired core ratio).Type: ApplicationFiled: July 6, 2007Publication date: October 1, 2009Applicant: REVWIRES LLCInventors: Donovan Karnes, Philip V.
