Abstract: A sensor assembly for attachment underneath a screen of a combine harvester is provided with a plurality of sensor units having sensor elements, a plurality of which sensor units are arranged one behind the other within a hollow profile which extends in the longitudinal direction of the screen.

Abstract: A sensor unit for use in the multiphase flow of a harvesting machine, wherein the sensor unit exhibits sensors for transmitting and/or receiving electromagnetic radiation. In addition, the sensor unit has at least one device for acquiring flow parameters of the multiphase flow. The measuring values of the sensor unit can advantageously be used for controlling the operating mode of the harvesting machine.

Abstract: A locking system comprises a lock cylinder which has a cylinder housing, a cylinder core rotatably supported in the cylinder housing and having a keyway, and has a plurality of tumblers which partly project into the keyway, and which furthermore comprises a key which has a key bow and a key shaft which has a shaft profile for acting on the tumblers. An abutment section is formed at the key shaft between the key bow and the shaft profile, said abutment section having an abutment profile having at least one projection and an undercut formed between the projection and the shaft profile. The lock cylinder furthermore comprises a movable counter-abutment.

Abstract: In a method of producing an exhaust-gas heat exchanger of a motor vehicle, at least one component of the exhaust-gas heat exchanger, e.g. an outer jacket or ducts arranged in the outer jacket or metal sheets, is subjected to an electrochemical machining process to produce a homogenous and smooth surface. The electrochemical machining process may involve plasma-polishing or electro-polishing.
