Abstract: A device for a resin-injection process for manufacturing an elongate fiber-composite component is disclosed having an upper die and a lower die, wherein the lower die forms a mold cavity for receiving a fiber-layer stack. The inner contour of the mold cavity substantially corresponds to the outer contour of the fiber-composite component to be produced. The device includes a gate 4 for introducing a matrix material into the mold cavity 5, and flow ducts which convey the matrix material are provided on the inner walls of the mold cavity. A method for manufacturing elongate fiber-composite components is disclosed, wherein a stack of a plurality of cut-to-size fiber layers is laid up in the mold cavity of a die comprising an upper die and a lower die. A higher fiber density is produced in the end regions of the stack of fiber layers than in the remaining regions when closing the die.

Abstract: The invention provides a process for coating a cylindrical carrier structure with a predetermined amount (target take-up) of a coating suspension, wherein the carrier structure has a cylinder axis, two end faces, an encasing face and an axial length L and a large number of channels running from the first end face to the second end face. The process comprises: a) vertically aligning the cylinder axis of the carrier structure and filling the empty volume of the channels up to a predetermined height H1 starting from the lower end face, b) removing the excess coating suspension through the lower end face of the carrier structure down to the target take-up, c) turning the carrier structure 180°, so that the upper and lower end faces are exchanged one for the other, and d) repeating steps a) and b), wherein the height H2, up to which the channels are filled in this case is given by H2=L−x·H1 where x is between 0.8 and 1.0.

Abstract: A method for producing a nitrogen oxide storage material that contains at least one storage component in the form of particles of an oxide, carbonate or hydroxide of the elements magnesium, strontium, barium, lanthanum and cerium on a carrier material from the group consisting of doped cerium oxide, cerium/zirconium mixed oxide and aluminum oxide or mixtures of these. The method is carried out by suspending the support material in an aqueous solution of precursors of the storage components, this suspension is then introduced into a hot gas stream, the temperature of which is calculated so that, during a residence time of the suspension in the hot gas stream of less than one minute, the solvent of the suspension is evaporated out and the precursors of the storage components are thermally broken down and converted to the storage components before the storage material that forms in this way is separated from the stream of hot gases.

Abstract: A method for partially coating a cylindrical carrier body with a coating suspension, the carrier body having a cylindrical axis, two end faces, an envelope, and an axial length L, and being provided with a series of channels extending from the first end face to the second end face. A desired coating quantity of the coating suspension is applied onto the carrier body by vertically aligning the cylindrical axis and introducing the coating suspension into the channels through the lower end face. The carrier body, measured from the lower end face, is filled with a filling volume of the coating suspension which is metered, such that the carrier body is only filled up to a height that amounts to a predetermined fraction of its length L. Subsequently, excess coating suspension is removed downward so that the desired coating quantity remains on the carrier body.
