  • Method and device for detecting microbiologically induced corrosion
    Patent number: 6960288
    Abstract: The invention concerns a sensor and a method for detecting microbiologically induced corrosion in a metal structure, which consists in performing the following steps: providing a sensor comprising at least a first circular electrode (4) and a ring-shaped electrode (2) concentric with the first electrode, proximate to the structure (30) in contact with a corrosive medium; imparting for a time interval t a conditioning current between the two electrodes so as to initiate corrosion, the current being such that the central electrode is cathode and the ring-shaped electrode is anode; after the time interval t, coupling the two electrodes and measuring the current between the two electrodes; calculating the speed of corrosion from the measurement.

  • Use of fucane for regulating the reconstruction of connective tissue
    Patent number: 6559131
    Abstract: The invention concerns the use of fucanes for obtaining medicines for modulating metalloprotease and inhibiting leukocytic elastase. Said medicines help activate collagen synthesis inhibit proliferation of gingival fibroblasts, and activate proliferation of dermal fibroblasts. They are useful in particular for treating periodontal pathologies and dermal lesions.
