  • Patent number: 9874177
    Abstract: A device for mixing a gaseous fuel into an oxygen-containing gas flow of a gas-powered internal combustion engine includes a housing component having an inlet that connects to a gaseous fuel supply conduit and a slit that opens into an intake pipe. The slit has a longitudinal extension that is oriented approximately perpendicular to the axial direction of the intake pipe. A valve body is movable relative to the housing component. An annular gap between the valve body and an outlet opening of the housing component has a cross-sectional area that varies in accordance with changes in the position of the valve body relative to the housing component. The annular gap determines the flow-through cross-section of a passageway between the inlet and the outlet. Furthermore, a gaseous fuel flow exiting from the slit is directed approximately perpendicular to the axial direction of the intake pipe.

  • Publication number: 20080108506
    Abstract: The resistive current-limiting device contains a strip-shaped superconductor having a conductive structure which is made of a metallic substrate strip, an insulating, oxidic buffer layer, a super-conductive layer made of a type AB2Cu3Ox oxidically high-Tc-super conductive material, an insulating buffer layer which is arranged therebetween, and a metal cover layer. At least one of the lateral edges of the conductive structure is mechanically deformed such that the cover layer and the substrate strip are arranged in electric contact.
