Abstract: A method determines state information relating to a belt grinder. The belt grinder has at least one abrasive belt for grinding a workpiece. The method includes providing measurement data relating to the belt grinder, and determining the state information from the measurement data using a machine learning system. The machine learning system is configured to determine the state information based on the provided measurement data.

Abstract: The invention relates to a temperature measurement system for measuring a temperature of a tube, comprising a temperature sensor contained in a housing having a contact surface which is connected to an outer surface of the tube, wherein the contact surface has a concave form matching a form of the outer surface of the tube, and wherein a temperature-conductive, flexible intermediate layer is arranged between the contact surface and the outer surface of the tube. A further object is a flowmeter, particularly a Coriolis mass flowmeter, comprising the temperature measurement system.

Abstract: The invention relates to a Coriolis mass flow meter with improved zero point stability. The Coriolis mass flow meter has a pair of U-shaped measuring tubes. According to one embodiment of the invention, the Coriolis mass flow meter comprises a special housing for vibration compensation or vibration suppression in the region of the process connectors. Additionally or alternatively, a specific mass distribution of the vibration exciter and/or vibration sensor is provided, in order to neutralize unwanted vibrations by actively causing vibration.

Abstract: A filter device, especially for filtering the intake air of an internal combustion engine, which includes a housing with an unfiltered air inlet and a clean air outlet, and a substantially cylindrical, replaceable filter insert disposed in the housing, which separates an unfiltered air zone within the housing from a clean air zone. An axial seal is provided on at least one end disk of the cylindrical filter insert, which seal interacts with a sealing surface on the housing to seal the unfiltered air zone from the clean air zone. A clamping wedge is also provided, which exerts a force on the filter insert to urge the axial seal reliably against the sealing surface of the filter housing.

Abstract: An intake system 10 which can be used for cooling a battery in a motor vehicle. This intake system 10 has a raw air inlet 11, a raw air duct 12, a filter housing 13, a filter element 14, a clean air outlet 15, a clean air duct 16 and an intake air manifold 17. The filter element 14 is placed in the filter housing 13 such that the air which flows from the raw air inlet 11 through the raw air duct 12 into the filter housing 13, must pass through the filter element 14 before it reaches the clean air duct 16 to the intake air manifold 17. The filter element 14 also has a curvature by which it at least partially follows the contour of a battery box wall 18 of an adjacent battery box 19. The filter element 14 can be made curved or in multiple parts.
