  • Patent number: 11965451
    Abstract: The invention relates to a mixer for an exhaust gas system for mixing an additive into an exhaust gas flow of an internal combustion engine, having a first shell and at least a second shell which are arranged successively in the circumferential direction in relation to a center axis, each shell having at least two shell edges that are arranged offset in the circumferential direction and which each form a flow edge, wherein the flow edges of two circumferentially adjacent shell edges of two different shells delimit an inflow opening, such that at least one pipe end arranged coaxially with the center axis is provided with a circumferential pipe profile that has a nominal radius Rn and is used for connection to an exhaust pipe, the pipe end being formed by the circumferentially adjacent shells.
    Type: Grant

  • Patent number: 9440276
    Abstract: A shell muffler for an internal combustion engine that is formed of a first shell and at least one second shell, which shells are connected at their respective edge regions BS so as to form the shell muffler, each edge region BS having a box-like inner contour KSi, which has four corner regions (E1)-(E4) and a width (B) and a length (L), and an outer contour KSa, and each shell being produced from a shell blank R, which is formed by deforming a sheet metal strip using a deep drawing tool having the shape of the shell, the blank R, after deforming, having an edge region BR with an outer contour KR, said edge region being removed at least partially after the blank R has been cut to size so as to form the outer contour KSa of the edge region BS of the shell.

  • Patent number: 4451438
    Abstract: A process for recovering one or more non-radioactive transition metal compounds from an ore containing one or more compounds of said transition metal or metals and further containing at least one complex of a member selected from the group consisting of uranium, thorium, radium, titanium, and rare earth metals, which comprises decomposing said ore in crushed condition by means of an acid so that a portion of the ore is brought into solution in a liquid phase and another portion of the ore remains in a solid phase, said compound or compounds of the transition metal or metals to be recovered passing into only the liquid or into only the solid phase, the uranium in the crushed ore being treated so as to cause substantially all of said uranium to be present in an oxidation state in which it cannot, during the decomposition step, pass into the phase containing the transition metal compound or compounds.
