This invention is directed to spiro-oxindole compounds, as stereoisomers, enantiomers, tautomers thereof or mixtures thereof; or pharmaceutically acceptable salts, solvates or prodrugs thereof, for the treatment andor prevention of sodium channel-mediated diseases or conditions, such as pain. The present invention further relates to dibenzofurans and dibenzothiophenes which comprise at least one nitrogen-bonded five-membered heterocyclic ring and at least one carbazolyl radical as substituents, to a process for preparation thereof, and to the use of these compounds in organic electronics. A motor is connected to rotate the drum. The user is allowed to control the flow speed and flow direction and select any link so as to view a full presentation of the related content in a presentation zone. An outer shell for the closure includes radial driving lugs extending in a radially inward direction from an outer skirt. A washing water tank is selectively connected to the first and second tanks 42 and, and the oven can be connected to a compressed air supply source and an inert gas source.
