摘要： A method for operating a water electrolysis device for produces hydrogen and oxygen from water. A throughflow direction is reversed by way of a suitable activation of valves (17, 18) in order to increase a service life of a PEM electrolyzer (1). This is effected periodically such that an equal throughflow in both directions is effected, by which the service life is increased.

摘要： A method for reversing a tubular knitted article (S) is disclosed. According to the method, the tubular knitted article (S), engaged at a first end thereof by a pick-up device (5) and hanging with a second end thereof from the pick-up device, is introduced in a reversing tube (15). The reversing tube (15) is moved through the pick-up device (5) so as to project with the upper end (15B) thereof above the pick-up device; and the reversing tube (15) is moved reciprocatingly up and down between an upper position and a lower position, while co-acting with a top clamping device (31) and a bottom clamping device (35) until the tubular knitted article (S) is entirely everted on the outer surface of the reversing tube (15).

摘要： A method for roughening a cylinder bore wall to be coated of a component, at least one groove, running around the central longitudinal axis, and at least one associated groove web, are generated such that the at least one groove web, in a radial direction directed toward the central longitudinal axis, forms first undercuts for a coating which is to be applied. Axial grooves running in the cylinder bore wall transversely to the at least one groove are generated such that the at least one groove web, in a peripheral direction about the central longitudinal axis, forms respective second undercuts for the coating which is to be applied. An adhesion of the coating which is to be applied, in the peripheral direction, is improved, so that stress cracks or detachments owing to a different thermal expansion of the component and of the coating which is to be applied are avoided.

摘要： A mixer for an exhaust system of an internal combustion engine includes a mixer housing (40) with an inflow opening central axis (LE) and with an outflow opening (38). A first flow duct (48) following the inflow opening (24) in the mixer housing (40) and a second flow duct (50) lead parallel to one another to a third flow duct (54) and open into same. The third flow duct (54) leads to the outflow opening (38). The first flow duct (48) and the second flow duct (50) are provided between an outer wall (16) of the mixer housing (40) and a flow divider wall (36) enclosed by the outer wall (16), and the third flow duct (54) is enclosed by the flow divider wall (36).

摘要： A system (100) detects hazardous situations in a medical setting. A sensor unit (110) has optical sensors (112) to determine a sensor signal (114), and to output same in real time, which includes sensor data indicating a sequence of three-dimensional views of a monitored area (102) over a monitoring time. A processor unit (12) identifies a number of objects (122) to be protected based on the three-dimensional views, detects hazardous objects (124) based on the three-dimensional views, determines a number of object pairs (105), monitors positions of the protected objects and hazardous objects of the object pair over the monitoring time, assigns hazard values to the object pairs, calculates current hazard values for object pairs up to a current time over an analysis time interval and outputs a corresponding alarm signal (126) if a calculated hazard exceeds a threshold value. An output unit (130) triggers an alarm.

摘要： A mixer for an exhaust system of an internal combustion engine includes a first mixer part (12) with a plate shape body (14) having an incoming upstream flow side (18), with respect to an exhaust gas main flow direction (A) and a downstream outflow side (22), and a second mixer part (24), on an outflow side, with a bottom wall (26) spaced apart from the plate shape body and with two side walls (28, 30), extending from the bottom wall (26) towards the plate shape body and fixed at the first mixer part. The mixer parts define a reactant injection duct (32) receiving reactant in a main injection direction (R). An exhaust gas main passage opening (54) the plate shape body opens towards the reactant injection duct with a plurality of exhaust gas secondary passage openings (78, 80, 82, 84, 86, 88, 90, 92) run past the injection duct.
