Abstract: A device for laser projection comprises a first laser diode configured to emit a first linearly polarized laser beam extending along a first polarization axis and a second laser diode configured to emit a second linearly polarized laser beam extending along a second polarization axis that is perpendicular to the first polarization axis. A polarization combiner is configured to combine the first and second linearly polarizing laser beams into a combined laser beam, wherein the combined laser beam comprises one of: (1) circular polarization; and (2) elliptical polarization. A measuring device is configured to measure an intensity of the combined laser beam. A control unit is configured to receive the measured intensity of the combined laser beam and is further configured to adjust an intensity of at least one of: (1) the first laser diode; and (2) the second laser diode.

Abstract: Flat gasket with a gasket plate which has at least one sheet metal layer which consists of a spring steel sheet, has elastic properties and is provided with at least one bead, which can be deformed elastically in its height and is subject to a dynamic pressure load under conditions of use of the flat gasket, and in order to achieve a greater operative range of the bead without reducing its durability consists of an austenitic steel according to the European standard EN 10088-2-1.4372.

Abstract: A gassing incubator for cultivating human or animal cells or tissues is known that has an inner case which can be closed by a door and is surrounded by a thermally insulating outer case. The outer case is spaced away from the side walls, back wall and roof of the inner case. Electrical heaters are disposed under the floor of the inner case and in the area of the side walls. The incubator has a means for humidifying the inner chamber atmosphere.
