    Abstract: In a method for automated determination of the relative position between a first hole on a first microsystem component, and a second hole on a second microsystem component, the two holes lie in a liquid medium. Under the supervision of a control device, the first and second microsystem components are displaced relative to one another into different relative positions. Electrical signals are delivered to one of the two microsystem components and are recorded on the other of the two microsystem components as measurement values which depend on the relative position of the two microsystem components with respect to one another. For different relative positions between the two microsystem components, measurement values are determined to determine that relative position in which the two microsystem components are positioned with respect to one another in such a way that their holes are mutually aligned.

  • Patent number: 7776191
    Abstract: Cathodes for aluminum electrolysis cells are formed of cathode blocks and current collector bars attached to those blocks. The cathode block has a cathode slot for receiving the collector bar and has a higher depth at a center than at both lateral edges of the cathode block. Additionally, the collector bar thickness is higher at the center than at both lateral edges of the cathode block. This cathode configuration provides a more even current distribution and, thus, a longer useful lifetime of such cathodes and increases cell productivity.

  • Patent number: 7749362
    Abstract: A method of protecting steel in concrete is disclosed. 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.

    Abstract: 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).
