Abstract: A method for manufacturing a multilayer fiber structure includes providing a receiving surface being formed by a first surface region of a contoured tool surface of a forming tool component and a support surface of a support component. Further, at least one fiber layer is formed on the receiving surface by laying down a plurality of fiber tapes onto the receiving surface. A roller device is positioned so as to press the at least one fiber layer against the tool surface and the support component and the roller device are synchronously moved along a curved transition region connects the first surface region to a second surface region of the tool surface. Thereby the at least one fiber layer is abutted against the transition region and the second surface region of the tool surface. Further, a tool system for manufacturing a multilayer fiber structure is disclosed.

Abstract: A fiber composite component having a first and a second fiber composite element each bent along a transverse axis opf the fiber composite component to have, respectively, in succession, a first and second base flange, a first and second web section, a first and second top flange and a first and second stiffening web. Respectively, the first and second base flanges are parallel to the first and second top flanges, the first and second web sections are angled with respect to each of the first and second base flanges and the first and second top flanges, the first and second stiffening webs are at right angles with respect to the first and second top flanges, and the first stiffening web and the second stiffening web are congruent with respect to one another, and are connected to one another, along a longitudinal axis of the fiber composite component.

Abstract: An exhaust gate, in particular for a heavy-goods vehicle, has a housing, which has an inlet and first and second outlets, on which first and second valve seats are formed, and a valve flap, which can be pivoted between the two valve seats to close the first or second outlet. The housing is formed as a cast part, which connects the inlet and at least the first outlet integrally to each other. The valve flap has a larger cross section than the inlet and the first and second valve seats.

Abstract: A waste heat utilization device for a motor vehicle includes a waste heat utilization circuit in which a working medium circulates. The water heat utilization circuit includes a conveying device, an evaporator, an expansion machine, and a condenser. The waste heat utilization device also includes an electrical generator in direct or indirect drive connection with a power take-off shaft of an internal combustion engine. The expansion machine is in direct drive connection with the power take-off shaft of the internal combustion engine for purposes of energy recirculation.

Abstract: In a method for manufacturing components from composite fiber materials, at least one placeholder is inserted into a recess in a molding tool, wherein the unfinished component is subsequently produced, the placeholder is removed, at least one lifting pad is inserted into the recess and the unfinished component is removed from the molding tool by inflating the lifting pad. In a system for manufacturing components from composite fiber materials, the component removal process is monitored and controlled by a computer unit in order to prevent predetermined maximum component loads from being exceeded. The gentle component removal process makes it possible to avoid consequential costs for repairing or reworking the components.

Abstract: Described herein are devices and methods for implementing a transceiver with independently controlled components. The components may include a programmable digital portion, a dedicated digital portion, and an analog portion. Each independently controlled component includes a programmable controller that resides in the programmable digital portion of the component that controls components in the dedicated digital or analog portions using state transition information.
