Abstract: A catalyst assembly includes a housing having at least first and second recesses with side surfaces, and a catalyst carrier body fixed in said housing. The catalyst carrier body has a casing tube and a honeycomb body through which an exhaust gas can flow. The casing tube has at least first and second protuberances with side surfaces and said casing tube is connected to said honeycomb body at least in a partial region. The protuberances extend at least partially into said recesses to form a fixed mounting and at least one floating mounting with an axial mounting play. The assembly ensures that the catalyst carrier body is permanently fixed, in particular during structure-borne vibrations that occur in the exhaust system of an internal combustion engine.

Abstract: An assembly includes a honeycomb body secured by an inner casing tube in a housing, in particular a housing of an exhaust system of an internal combustion engine. The inner casing tube has an overall length which is bounded axially by two edges and is substantially smaller than the axial length of the honeycomb body. The inner casing tube is also disposed in an approximately axially central position around the honeycomb body and is connected, in particular brazed, thereto in at least one axial connection region. The inner casing tube has a region within the axial connection region in which it is connected to the honeycomb body on the inside or attached directly adjacent the latter on the outside and is connected to the housing. Regions of the inner casing tube which are not connected to the housing but are connected to the honeycomb body toward the inside are constructed as radially elastic spring elements. In this way, a resilient attachment, which adapts to deformations of the honeycomb body, is produced without tearing. That is advantageous in particular in the case of honeycomb bodies made of very thin sheet-metal layers, in particular thinner than 0.03 mm.

Abstract: A method and an apparatus produce a connection of at least at one end surface of a carrier matrix of a honeycomb body, in particular a catalyst carrier body, by a joining technique. The matrix is disposed in a tubular jacket and is laminated and/or wound from at least partially structured sheet metal foils or layers. The end surface of the honeycomb body is at least partially heated up with the aid of a surface inductor having induction coils. The induction coils are disposed in such a way that interconnections of the sheet metal foils or layers are established at least at locations, in particular at spots. Such connecting spots are preferably established variably with regard to their extent over the end surface. The surface inductor is variable with regard to the production of connecting locations and/or connecting spots, that is with regard to effective regions. The invention is suitable in particular for connections made by joining techniques such as brazing or sintering and can be applied while the process of producing catalyst carrier bodies is in progress.
