  • Publication number: 20090302729
    Abstract: A flat lighting device includes a layer arrangement, anode and cathode contact regions. The layer arrangement includes an anode layer, a cathode layer, and an organic light-emitting layer arranged between the anode and cathode layers, the layer arrangement having a flat shape which is laterally bounded by an edge region. The anode contact regions contact the anode layer and are implemented along the edge region. The cathode contact regions contact the cathode layer and are implemented along the edge region. The flat shape has a rotational invariance toward rotation by discrete angles. The anode and cathode contact regions may be contacted from one side of the flat shape of the layer arrangement and are arranged to be laterally distributed over the edge region such that the lateral distribution of the anode and cathode contact regions is maintained upon rotation of the layer arrangement by the discrete angles.

  • Publication number: 20090285736
    Abstract: The invention provides a process for reducing the amounts of carbon monoxide, hydrocarbons and soot particles in the lean exhaust gas from an internal combustion engine using a particle filter, wherein the soot particles have a soot ignition temperature TZ and the particle filter is regenerated from time to time by raising the temperature of the particle filter to above the soot ignition temperature and burning the soot particles, wherein the temperature of the filter is increased to the temperature required to initiate soot ignition by burning additional fuel on the catalytic coating when the exhaust gas back pressure reaches a predetermined value. The process is characterised in that the particle filter is provided with a catalytic coating comprising a first group of components for reducing the ignition temperature of soot, said first group of components contains at least one oxygen storage component and at least one platinum group metal selected from the group consisting of platinum, palladium and rhodium.

  • Patent number: 7278282
    Abstract: A device for transferring an object from a dead plate of an Individual Section glass-forming machine to a conveyor belt is disclosed. The device includes a first shaft rotatable about an axis. A housing is attached to the first shaft. A carrying arm is slidably mounted on the housing and has a finger at one end for engaging the object. A guide piece having a groove is attached to the other end of the carrying arm. A crank arm engages the groove. The crank arm is connected to a second shaft coaxial with the first shaft. The shafts rotate independently of one another. Each shaft has its own drive unit. Rotation of the first shaft rotates the carrying arm about the first axis and rotation of the second shaft causes sliding motion of the carrying arm along its longitudinal axis.

  • Publication number: 20070032753
    Abstract: A massage device having a permanent magnet with a central opening. Disposed within the central opening of the permanent magnet is an electromagnetic coil. The coil is connected to a musical source adapted to generate an electrical signal corresponding to the music output. A flexible cover is fitted over an open end of the permanent magnet. The charge of the electrical signal causes the coil to interact with the permanent magnet and move back and forth within. As the coil moves, the coil engages the flexible cover pushing the cover away from the open end of the permanent magnet.
