  • Patent number: 7955790
    Abstract: The present invention relates to in vitro cultured skin substitutes, and in particular to in vitro cultured skin substitutes that have improved barrier function. In some embodiments, improved barrier function is a result of improved culture conditions, while in other embodiments, improved barrier function results from genetic modification of keratinocytes. Improved culture conditions to improve barrier function include organotypic culture in the presence of linoleic acid and/or linoleic acid at about 75% humidity. Suitable genetic modifications for improving barrier function includes transfection with a DNA construct capable of expressing GKLF.

  • Patent number: 7913518
    Abstract: A process and a device for pushing hollow glass objects off a glass forming machine onto a moving conveyor belt are disclosed. Each hollow glass object is pushed by a push-off unit from a dead plate along a curved path onto the conveyor belt in such a way that the curved path is brought tangentially to a contact point in a movement direction of the conveyor belt. Subsequent to the contact point each hollow glass object is pushed further by the push-off unit by a further linear path portion in the movement direction of the conveyor belt as far as a release point at which the push-off unit is released from the hollow glass object. The push-off unit is then moved back to dead plate.

  • Publication number: 20110060855
    Abstract: The invention relates to a bus coupler which converts a network-specific telegram arriving from an external network to an internal data telegram which transmits only the payload data from the network-specific telegram. The internal data telegram also contains at least one state information field for internal control information. The internal data telegram is transferred from the bus coupler to an internal bus system to which multiple bus users are connected in series. Each bus user connected to the internal bus system is able to monitor, in a decentralized and preferably autonomous manner, the communication quality of the lower-level bus system, and to initiate actions, depending on the implementation, on the basis of the internal control information received from the bus coupler, the internal control information generated by the particular bus user, and/or the internal control information received from the directly adjacent bus users.

  • Patent number: 7897120
    Abstract: A charging device for a tube reactor has a plurality of metering chambers which can be filled with filling material, for example a catalytically coated carrier material. Each metering chamber is adjoined by a drop tube or some other filling device via which a tube of the filling device can be filled in each case. The metering chambers can each be filled via antechambers which are combined into one replaceable antechamber unit.

  • Publication number: 20110009955
    Abstract: The invention concerns oligosaccharides and polysaccharides as well as the use of these oligosaccharides and/or polysaccharides, which contain the sugar unit N-acylglucosamine or N-acylgalactosamine for the production of hemocompatible surfaces as well as methods for the hemocompatible coating of surfaces with said oligosaccharides and/or polysaccharides, which imitate the common biosynthetic precursor substance of heparin, heparan sulphates and chitosan. The invention further describes methods for producing said oligosaccharides and/or polysaccharides and discloses various possibilities of using hemocompatibly coated surfaces. The invention relates particularly to the use of said oligosaccharides and/or polysaccharides on stents with at least one according to invention deposited hemocompatible coating, which contains an antiproliferative, antiinflammatory and/or antithrombotic active agent, methods for the preparation of said stents as well as the use of said stents for the prevention of restenosis.

  • Patent number: 7865648
    Abstract: The invention pertains to a modular data transmission system with several modules or bus nodes that can be arranged adjacent to one another in a row. The data transmission system comprises a first bus node that features a first transmitter for the wireless transmission of data and an electrical connector, as well as a second bus node that features a first receiver for the wireless reception of data and an electrical connector. Both bus nodes are detachably fixed on a mounting rail such that they are arranged adjacent to one another in a row. The first and second bus nodes are respectively detachably connected to a bus receptacle, wherein each bus receptacle features an electrical mating connector that is coupled to the electrical connector of the respective bus node in the connected state in order to transmit energy, as well as a positioning device for positioning the respective bus node.
