  • Patent number: 6410147
    Abstract: The present invention is directed to a low gloss crosslinkable coating composition that produces a low gloss coating upon cure. The crosslinkable composition includes a binder component and a crosslinking agent. The binder component includes a combination of at least two partially compatible crosslinkable components retained in an evaporable medium, such that the low gloss coating exhibits a 60° specular gloss that is at least 5% lower than gloss of coatings from coating compositions containing any one of the crosslinkable components. The low gloss coating composition of the present invention is especially suited for OEM and refinish automotive coating applications, such as automotive fenders and automotive side boards, typically used in sport utility vehicles.

  • Patent number: 5766949
    Abstract: An apparatus for cultivating cells as disclosed includes a cell culture chamber having inlet and outlet ports, a substrate (7) with an anchorage surface for attachment of cells, and a system for circulating a culture medium in the cell culture chamber through the inlet and outlet ports. The medium circulating system cooperates with valves to control the surface level of the medium in order to submerge the anchorage surface in the culture medium and intermittently expose the substrate from the culture medium, thereby increasing the rate of gas exchange through a thin film of the culture medium formed on the anchorage surface. A method for cultivating cells by using the apparatus is also disclosed.
