Abstract: A method for determining a concentration of an analyte in a sample stream containing the analyte and a solvent includes: preparing a measured stream by diluting the sample stream with a solvent stream; ascertaining a concentration of the analyte in the measured stream; and ascertaining the concentration of the analyte in the sample stream as a function of the measured stream concentration and a dilution ratio of sample stream and measured stream. An apparatus of the invention includes: a first Coriolis mass flow measuring device for measuring a solvent stream as a function of the sample stream for diluting the sample stream; a second Coriolis device for ascertaining a mass flow of the measured stream; a density measuring device for ascertaining a density of the measured stream; and a computing and operating unit for computing the concentration of the analyte in the sample stream.

Abstract: A method for checking the association of structure-borne noise sensors of an internal combustion engine having a plurality of cylinders, which internal combustion engine can be operated in diesel operation or with individualized gas injection and in the case of which internal combustion engine a structure-borne noise sensor is arranged in the region of each cylinder, wherein the output signals of the structure-borne noise sensors reflect a knock index and are captured by a computing unit, wherein the internal combustion engine is operated in order to perform the method. The output signals of all structure-borne noise sensors are determined during at least one working cycle, which is formed by two revolutions of a crankshaft, in the respective positions of the crankshaft. The output signal of a cylinder is compared with the average value or the median value of the output signals of other cylinders.

Abstract: The invention relates to a mechanical seal arrangement for sealing on a rotating component (21), comprising a slide ring seal (2) having a rotating slide ring (3) and a stationary slide ring (4), which define a sealing gap (5) between the sliding surfaces (3a, 4a) thereof, a recirculation conveyor (7) arranged adjacent to the rotating slide ring (3) wherein the recirculation conveyor (7) comprises a recirculation line (19) in which a cooling device (20) for cooling the recirculated fluid is arranged, a recirculation rotor (8) and a hollow cylindrical housing (9), wherein the recirculation line (19) leads to a cavity (6) in the region of the sealing gap (5) of the sliding ring seal (2), wherein the hollow cylindrical housing (9) comprises an inner shell surface (11) and an outer shell surface (12) and wherein a conveyor channel (10) is provided on the outer shell surface (12), which conveyor channel (10) is formed along the outer shell surface (12) from a start portion (13) to an end portion (14) wherein the s

Abstract: A system and method for filling liquid products into bottles are described. The system comprises a machine block with a blow-molding machine for providing a flow of bottles, with a labeler for labeling the flow of bottles, with a first and second transport stretch, each comprising a filler for filling the bottles, and with a distribution unit dividing the labeled flow of bottles to the transport stretches when the transport is fully populated at all circulating labeling positions of the labeler and all circulating filling positions of the fillers. The filling system comprises outflow conveyors downstream of the fillers, with a combining device for combining the transport stretches to form a common outflow for the flow of bottles, thereby reducing the transport speed during filling and subsequent handling of the bottles, as well as problems due to the product in the bottles spilling over during the closure process.

Abstract: Methods and computer-readable media for producing at least one portion of a layer of a three-dimensional component by irradiating at least one powder layer by at least one high-energy beam, e.g., a laser beam are disclosed. The methods include irradiating the powder layer by the at least one high-energy beam in a processing field, wherein the at least one high-energy beam is moved in a continuous oscillating movement over the powder layer in a first direction to produce a line-shaped irradiation region in which the powder layer is melted, and wherein the line-shaped irradiation region is moved over the powder layer in a second direction that differs from the first to produce the portion of the layer of the three-dimensional component.

Abstract: A method for generating a sectional view of a body of a vehicle includes displaying a first sectional view of the vehicle body on a screen, where the first sectional view comprises two surfaces of two components of the vehicle body which adjoin one another at a first transition point. The method includes displaying a joint catalog with a plurality of predefined joint types, where one joint type of the plurality of predefined joint types defines a predefined joint section for a joint between two surfaces. The method also includes detecting a selection of a first joint type from the joint catalog, and automatically inserting the predefined joint section for the first joint type at the first transition point into the first sectional view displayed on the screen, with the result that the surfaces of the two components are connected to one another at the first transition point by the joint section.

Abstract: A machine element, in particular for a shaping machine, includes a lubricated bearing and/or a seal and a primary drainage conduit for catching a fluid medium issuing from the bearing and/or the seal, preferably substantially pressure-lessly. A collecting device is provided for collecting the fluid medium which is caught in the primary drainage conduit over a period of time, and a measuring device is adapted to directly and/or indirectly measure an amount of the fluid medium collected by the collecting device over the period of time.

Abstract: The disclosure provides methods of additive manufacture of components in layers in a powder bed by at least two laser beams that can be deflected two-dimensionally over the same powder bed region. Each laser focal spot is projected onto the power bed and is or is set to a diameter of less than or equal to 300 ?m. Components to be produced in the powder bed region are manufactured by each of the laser beams, and each individual surface contour of the component is manufactured solely by one of the laser beams.
