Abstract: An actuator assembly is capable of manipulating a fluid flowing around a flow body, the fluid being received or able to be received in a volume of at least one cavity arranged in the flow body, and the fluid passing through at least one opening in the at least one cavity during manipulation of the fluid. In this process, the volume of the at least one cavity can be changed by moving a wall portion delimiting or defining the cavity. The actuator assembly has a drive unit with at least one actuator, which executes a periodic movement over time when actuated, causing a translational movement of the wall portion delimiting or defining the cavity and the wall portion being shaped in terms the topology thereof in such a way that it is adapted to the shape of the at least one cavity with the at least one opening thereof.

Abstract: A composite material includes a magnesium alloy and a layer consisting of nanoscale graphene platelets on at least a part of the surface of the magnesium alloy. A process for manufacturing such a composite material includes providing a magnesium alloy, providing nanoscale graphene platelets and applying the nanoscale graphene platelets to at least a part of the surface of the magnesium alloy.

Abstract: A method for manufacturing an electrode comprises the steps of applying a suspension of a suspension medium containing a solvent and electrically conductive carbon allotropes on a substrate, generating an electric field that penetrates the suspension and has a predefined field direction in order to align the carbon allotropes in the field direction, and removing the solvent from the suspension medium in order to harden the suspension in the aligned state of the carbon allotropes. A thusly manufactured electrode leads to a higher capacity, a higher charging and discharging rate, i.e. the delivery of a higher electric current, as well as shorter charging and discharging times of secondary batteries.

Abstract: The invention provides a method and apparatus for forming a freeform metal structure by wire feed additive manufacturing, wherein a metal wire end is moved along an area of deposition and is melted by a heat source, the melting being deposited on the metal structure as a metallic build-up material, wherein during the cooling process build-up material is subjected to at least one pulsed magnetic field effecting plastic deformation of the build-up material.

Abstract: A structural element, in particular for an aircraft, such as an airplane, contains a laminate having a plurality of layers made of a fiber composite plastics material with carbon fibers, a lightning protection layer and optionally an electrically insulating dielectric protection layer. The laminate contains at least one hybrid layer, which comprises a carbon fiber-absorption fiber composite, the elongation at break of the absorption fiber being greater than the elongation at break of the carbon fibers.

Abstract: Specified is a lightning protection layer for an aircraft. The lightning protection layer has a first stratum and a second stratum. The second stratum is coupled to the first stratum along a connecting surface. The first stratum has a metal foil and the second stratum has carbon allotropes. It is thus made possible that damage to a structure of the aircraft by lightning strike is reduced.

Abstract: An induction heating system and a method for controlling a process temperature for induction heating of a workpiece. The induction heating system comprises an inductor configured to generate an alternating magnetic field in response to an alternating current supplied thereto, a magnetic load comprising a magnetic material, the magnetic material having a Curie temperature and being configured to generate heat in response to the alternating magnetic field being applied thereto, the magnetic load being connectable to the workpiece in a heat-conducting manner so as to transfer the generated heat to the workpiece, and a control unit configured to control the process temperature for manufacturing the workpiece by adjusting the alternating magnetic field when the temperature of the magnetic material is in a temperature control range around or below the Curie temperature of the magnetic material, the temperature control range being dependent on the magnetic material of the magnetic load.

Abstract: A device for pressing a gear rack against a pinion meshing with the gear rack, e.g., in a rack-and-pinion steering system for a motor vehicle, includes a thrust piece, which is loaded by a spring in the direction of the gear rack and is slidably guided in a housing. The thrust piece takes the form of a sintered part, which has a plurality of depressions on its circumferential surface. The regions of the circumferential surface, which are elevated with respect to the depressions, produce the contact of the thrust piece with the housing.

Abstract: A rack-and-pinion electro-steering system, e.g., for motor vehicles, has a rack extending in a housing, which is operatively connected to a thrust member/pinion pairing. At least one bearing between the rack and the housing is provided for guiding the rack. The bearing is arranged as a friction bearing. A construction of the bearing between the rack and the housing as a sliding bearing may be particularly suited for a reliable, durable and cost-effective guidance of the rack in the housing. In addition, for mounting the sliding bearings on the rack, a lock geometry is provided by which the sliding bearings may be locked after having been mounted on the rack. The lock geometry for example may be based on the lock geometry customary in sealing rings in automatic transmissions.
