Abstract: A manufacturing device for additive manufacture of components includes a beam generation device configured to generate energy beams, a scanner device configured to locally and selectively irradiate a working region with the energy beams, a protective gas device configured to generate a protective gas flow over the working region, and a control device configured to drive the scanner device. The control device is configured to define a first irradiation region along which a first irradiation section is displaced from a first starting position to a first end position, to define a second irradiation region along which a second irradiation section is displaced from a second starting position to a second end position, and to begin irradiation of the second irradiation region when the first irradiation section and the second starting position are not arranged within an interaction zone defined by a protective gas flow direction relative to one another.

Abstract: The invention relates to a fail-safe rotary actuator (1) for a coolant circuit, in particular for a coolant circuit of an internal combustion engine (2) having a plurality of sub-circuits (3) and (4), includes a coolant delivery pump (5) for circulating the coolant within the coolant circuit, and having a rotary-slide housing (8) which has a plurality of housing pass-through openings (6) and (7) and in which at least one rotary slide (9) having at least one rotary slide pass-through opening (11) and (12) is rotatably supported, wherein the housing pass-through openings (6) and/or (7) are fluidly connected to at least one sub-circuit (3) and/or (4), and can be brought into at least partial coincidence with the rotary slide pass-through openings (11) and/or (12) by a rotary motion of the rotary slide (9), wherein a thermostat valve (13) opens a flow path running parallel to the rotary slide (9) from one of the sub-circuits (3) or (4) to the coolant delivery pump (5), when a temperature limit of the coolant is e
