  • Patent number: 8481726
    Abstract: The present invention relates to a novel process for the preparation of specific sterically hindered nitroxyl ethers from their corresponding sterically hindered nitroxyl radicals by reacting it with an aldehyde and a hydroperoxide. This nitroxyl ether formation may be carried out from different starting nitroxyl radicals, which are subsequently further reacted to the desired compounds. The compounds prepared by this process are effective as stabilizers for polymers against harmful effects of light, oxygen and/or heat and as flame-retardants for polymers.

  • Patent number: 8303626
    Abstract: The present invention relates to a device comprising a shaped shoulder piece to rest on the shoulders of a person to be treated, and a shaped head piece to be laid on it, as support for the chin and two bottom points of the rear lower edge of the skull. This ensures a three-point support of the head on the top side of this shaped head piece. Further, the device comprises a lifting mechanism, which is inserted between the back of the shaped shoulder piece and the shaped head piece. This lifting mechanism is simply a pump in the form of a bellows with a one-way valve for discharge, by which the air cushion can be inflated and discharged arbitrarily.

  • Patent number: 8287414
    Abstract: A continuously variable transmission device comprising a variator and a secondary power splitting. For power splitting, a planetary gear set has a first shaft coupled to the transmission input, a second shaft of the gear set coupled a first shaft of the variator, and a third shaft of the gear set couples a second shaft of the variator. First and second shift elements are provided to switch between first and second gear ratio ranges. Via the variator, the gear ratio is continuously variable within the gear ratio range and the two gear ratio ranges overlap. To implement the first gear ratio range, the second shaft of the gear set is connected, via the first shift element, to the transmission output, and to implement the second gear ratio range, the third shaft of the planetary gear set is connected, via the second shift element, to the transmission output.

  • Patent number: 7884198
    Abstract: The present invention encompasses monoclonal and chimeric antibodies that bind to lipoteichoic acid of Gram positive bacteria. The antibodies also bind to whole bacteria and enhance phagocytosis and killing of the bacteria in vitro and enhance protection from lethal infection in vivo. The mouse monoclonal antibody has been humanized and the resulting chimeric antibody provides a previously unknown means to diagnose, prevent and/or treat infections caused by gram positive bacteria bearing lipoteichoic acid. This invention also encompasses a peptide mimic of the lipoteichoic acid epitope binding site defined by the monoclonal antibody. This epitope or epitope peptide mimic identifies other antibodies that may bind to the lipoteichoic acid epitope. Moreover, the epitope or epitope peptide mimic provides a valuable substrate for the generation of vaccines or other therapeutics.
