  • Patent number: 8551306
    Abstract: A permanent cathode that is to be used as electrode in the electro-refining and/or recovery of metals, such as copper, zinc, cobalt or nickel. The permanent cathode comprises a planar mother plate that is made of metal and comprises two sides. The mother plate comprises an edge, which at least partly surrounds the metal plate. The edge comprises a groove portion that is provided with a groove. The groove portion comprises at least one bridging section for joining together, over the groove portion of the edge of the metal plate at the at least one bridging section, the cathode metal halves, such as cathode copper halves, cathode zinc halves, cathode cobalt halves or cathode nickel halves, which are formed on the sides of the mother plate in the electro-refining of the metals.

  • Patent number: 6342136
    Abstract: This invention applies to an electrolytic cell busbar construction for the purpose of the electrolytic recovery of metals. The construction is formed so that the gap between the electrodes can be changed easily. All parts of the construction are in the form of an integral profile longitudinally to the cell and the support lugs of the electrodes in the cell are unnotched.

  • Patent number: 6187156
    Abstract: The invention relates to an anode used in the electrolytic refining of copper, said anode (1) comprising two support parts (2), whereby the anode (1) is suspended during the electrolytic process against the electrolytic tank walls. According to the invention, in the anode support parts (2) there are formed brackets (3) for gripping the anode (1) and for supporting the anode (1) when it is being transferred from one position to another.

  • Patent number: 5420012
    Abstract: The invention relates to diagnosis of reactive conditions, such as malignant tumors. According to the invention, the amount of cellular fibronectin in a body fluid is determined, and an elevated amount is used as a marker for a reactive condition. The method is especially suitable for the diagnosis of carcinomas, such as colon carcinoma.
