Patents by Inventor Werner Schunk

Werner Schunk has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7045144
    Abstract: The invention relates to a plaster containing an active agent, comprising at least one cover membrane and an active membrane which is based on a skin-compatible matrix containing a molecular sieve which is loaded with at least one active agent. The molecular sieve/active agent adduct releases the active agent when the active membrane comes into contact with the skin, in conjunction with the transpired water of the skin. The inventive plaster is characterised in that the molecular sieve/active agent adduct also contains water of crystallisation, to the extent that the molecular sieve is partially hydrated compared to a sufficient basic molar quantity (m) of water of crystallisation, the molecular sieve with the reduced molar quantity (m?) of water of crystallisation being loaded with the active agent (Z, Z1, Z2) so that when the active membrane comes into contact with the skin, water is absorbed and the active agent is desorbed, whereupon the water of crystallisation content of the molecular sieve increases.

  • Patent number: 6976281
    Abstract: A medical cushion (1), in particular an anti-decubitus cushion, is in particular multicellular and is distinguished in that the cushion is equipped, at least in the area where skin contact (6) occurs, with an active membrane (3) based on a skin-compatible matrix (4) into which a molecular sieve is mixed. This molecular sieve is charged with at least one active substance (Z, Z1, Z2), and the molecular sieve/active substance adduct (5) releases the active substance when the active membrane comes into skin contact (6) in conjunction with the transpiration of the skin.

  • Publication number: 20040137296
    Abstract: The invention relates to a fuel cell (1) comprising at least the following components: a proton-conducting membrane (2) serving as an electrolyte; catalyst layers (3), which cover the membrane (2) on both sides; gas-permeable electrodes provided in the form of an anode (4) and a cathode (5), which rest against the outwardly pointing surface of the catalyst layers (3), and; electrically conductive plates (6), which contact the electrodes in an electrically conductive manner whereby being located close to one another and which, together with the electrodes, delimit gas-conducting channels. The fuel cell also comprises gas connections for supplying hydrogen (H2) on one side and oxygen (O2) on the other. The inventive fuel cell (1) is characterized in that the membrane (2) has a matrix into which a proton-conducting organic-based polymer substance is incorporated.
