  • Invasive medical device, especially for guided tissue regeneration
    Patent number: 7348020
    Abstract: Biodegradable invasive medical device, in particular for guided tissue regeneration, which device comprises a biodegradable polymer, composed of a thermoplastic and/or thermosetting polymer admixed to a solvent that is miscible with any aqueous and/or aqueous alcoholic and/or alcohol-group-containing solution and/or with physiological liquids, whether of a synthetic or natural type. The said water-insoluble thermoplastic and/or thermosetting polymer and the water-miscible solvent for the polymer and mixed together in such a proportion as to form an organogel or a plastigel or a xerogel, or a solid-containing pasty product of the slurry type.

  • Apparatus for preserving food by generating preservative gas
    Patent number: 4411918
    Abstract: The gas generating device according to the invention comprises a basin-like main container containing a solid chemical reagent substance, and an auxiliary container, arranged at the interior of the main container, containing a liquid chemical reagent substance.The main container is closed at its top by a cover lid in such a manner as to permit the outflow of gas generated at its interior. The gas generating device is accomodated at the interior of a storage or transport receptacle formed by a stack of superposed crates of fruits or vegetables, enclosed in a gas-tight wrapping of suitable plastic sheet material.
