Abstract: The present invention relates to a reactor having a multilayer structure, wherein the different layers are structured in a particular manner, in preferred embodiments comprising square openings to enable an improved heat transport during catalytic reactions. Furthermore, the present invention relates to multi-reactor structures, methods for providing the reactors and multi-reactor structures, as well as uses and applications.

Abstract: A spindle drive for an adjustment element of a motor vehicle, including a tubular drive housing having a first housing pipe, a spindle/spindle nut transmission configured to produce linear drive movements, a first drive connection and a second drive connection configured to discharge the drive movements, the first drive connection forms with one of the transmission components a first drive train component and the second drive connection forms with the other of the transmission components a second drive train component. A housing cover axially closing the drive housing and arranged in an axially secure manner relative to the first drive connection. The first housing pipe arranged in an axially secure manner relative to the first drive connection. A housing collar in a first coupling portion of the spindle drive connected to the first housing pipe and in a second coupling portion coupled to the housing cover.

Abstract: A drive arrangement for adjusting a front hood of a motor vehicle including a first drivetrain for producing a first drive movement between a flap-side drive connection and a body-side drive connection and when the first drivetrain is in a normal state the first drive movement opens the flap from a closed position to an open position. A second drivetrain for producing a second drive movement between a flap-side drive connection and a body-side drive connection to open the flap from the closed position to a collision position so that by means of the second drive movement of the second drive the first drivetrain changes from a normal state to a bypass state, in which a first strand component of the first drivetrain moves relative to a second strand component of the first drivetrain.

Abstract: A spindle drive for an adjustable element of a motor vehicle is provided with a drive unit having a drive unit housing formed in a materially uniform manner, the spindle drive having two drive portions which run in opposition to one another, the spindle-side drive portion having a torsion tube formed in a materially uniform manner with an engagement portion, and the spindle nut being in rotationally fixed but axially displaceable engagement with the engagement portion to form a torque support. The torsion tube has a fastening portion which is fastened to the drive unit housing in a rotationally fixed and axially fixed manner.
