Abstract: A torsional moment acting on a component in a drive train of an aircraft may be determined using at least one sensor, where the determined torsional moment is used for adjusting at least one adjustable damping element located in or on the component and/or for regulating a torsional stiffness in the torque-conducting component. As a result, the torsional load in the component may be reduced.

Abstract: An electronic unit for a vehicle, comprising surface elements arranged next to one another with a visible surface side and a surface underside is disclosed. The surface elements are fixed in a housing. The housing has a top side facing the surface underside and an underside, wherein a carrier plate is provided. Each housing on its underside has at least one protruding fixing element for fixing the surface elements to the carrier plate. The carrier plate connects the surface elements together, wherein each fixing element has an index element arranged on the fixing element between the carrier plate and the underside and is releasably connected to the fixing element. The index elements are connected to the carrier plate by substance bonding so each surface element is releasably fixed to the carrier plate, and wherein by the index elements, the surface elements are arranged relative to and level with one another.

Abstract: A method for producing a feeder (10) that is intended for use in a casting mold used for the casting of metals and comprises a feeder body (11), which encloses an inner cavity (25) as a feeder volume, consists of an exothermic and/or insulating material, has at least one lateral wall region (12) and a bottom region (13) with a feeder opening (14) arranged therein for connecting the inner cavity (25) of the feeder body (11) to the mold cavity of the casting mold during the casting operation and has a mesh-like fabric consisting of a refractory material covering over the feeder opening (14) therein, is characterized in that, in the course of the production of the feeder in a core shooter, a piece of fabric (21) of the mesh-like fabric is positioned in a pattern device (17) forming the shape of the feeder (10) in a core box (30) of the core shooter, in such a way that the peripheral region (22) of the piece of fabric (21) positioned in the bottom region (13) of the later feeder (10) is at least partially bent up

Abstract: In a method for producing a riser for inserting into a casting mold used for casting metals, the riser includes a riser body (31) surrounding an inner cavity (36) as a riser volume and is composed of an exothermic and/or insulating riser material (30). To produce a single-piece riser body (31) in a two-part core box (10), a cavity (14) reproducing the outer contour of the riser body (31) is formed and, in order to produce the inner cavity (36), a reversibly expandable king (15) is set in the cavity (14) in such a way that, in the shooting of the riser body (31), the wall region (32), the cup region (33), and the base region (34) of the riser body are formed by the riser material (30) introduced into the intermediate space (41) between the expanded king (15) and the inner wall (40) of the cavity (14).

Abstract: A transmitter for collecting human pulse by means of flexible bands comprising flexible bands projecting like wings from a transmission unit of a transmitter for human pulse measurement. The flexible bands have contact surfaces of the transmission unit on the inner side and can be stretched around a rib cage by means of a stretch band. To ensure reliable contact and comfortable wearing properties of the flexible bands, the flexible bands have holes each of which widens from the inner side towards the outer of the flexible bands.
