Abstract: Provided is a method for operating an internal combustion engine which includes at least one cylinder with a combustion chamber in which hydrogen fuel is combusted with air. In the combustion chamber, at least a flow of the hydrogen, at least in sections, carries out a rotational movement about at least one axis perpendicular to a longitudinal axis of the at least one cylinder. In order to provide a hydrogen/air mixture as homogeneous as possible which allows for low-emission and efficient combustion, the rotational movement of the flow about the axis perpendicular to the longitudinal axis of the at least one cylinder is induced by feeding in of the hydrogen.

Abstract: A method for severing a dough portion from a dough mass by a dough portioning device having a container, a first portioning roller having a plurality of severing edges and a second portioning roller having a plurality of severing edges, wherein a depression is respectively provided between two severing edges. The method comprises rotating the first and second portioning rollers into a receiving position, and receiving a part of the dough mass in two depressions of the first and second portioning rollers facing the container. The method further comprises rotating the first and second portioning rollers into a waiting position, decreasing rotational speeds of the first and second portioning rollers, waiting for a waiting time to elapse and increasing the rotational speeds of the first and second portioning rollers and rotating the first and second portioning rollers into a severing position.

Abstract: The invention relates to a micro-scale cooling element (1) having a mounting surface (2) for a constituent part, in particular a semiconductor component, that is to be cooled, which element is configured, in particular, cuboidally and has in the interior a micro-scale cooling structure (3) that is connected via connecting conduits (4) to at least one inflow opening (5) and at least one outflow opening (6) through which a cooling medium is conveyable to and dischargeable from the micro-scale structure (3), the micro-scale cooling element having a monolithic structure.

Abstract: A method reduces the noise in the drive train of a motor vehicle having an automatic transmission or a manual transmission with a controllable oil pressure supply and/or automatic starting clutch. An engine sided drive unit is connected to the transmission input shaft by way of a spline connection, wherein noises in the drive train are caused by a clearance fit in the spline connection between the engine sided drive unit and the transmission input shaft. The transmission control is adapted for reducing the noise when in neutral.
