Abstract: An electric machine having a stator arranged in a machine housing and a rotor mounted rotatably relative to the stator about an axis of rotation, wherein the machine housing includes at least one coolant inlet port for supplying coolant to the machine housing and at least one coolant outlet port for draining coolant from the machine housing. It is provided that the coolant inlet port empties into a distribution annulus and several housing coolant ducts emerge from the distribution annulus and extend beyond the stator, when viewed in the axial direction, and are connected fluidically, on their side facing away from the distribution annulus, to stator cooling duct inlets of stator cooling ducts formed in the stator, which pass entirely through the stator in the axial direction.

Abstract: A lighting device having a cell structure (101) of polygonal cells (105), which is a heat sink, and light sources (103) arranged to be cooled by the cell structure. The light sources are arranged in at least some of the cells, one light source in each cell. The light sources are attached to the cell structure and electrically connected with the cell structure, which in turn is arranged to provide the light sources with power.

Abstract: A mixing element has a grid which includes a plurality of rows parallel to each other and a plurality of deflector elements which project from the grid and are inclined in relation to the grid plane normal. All deflector elements of one row are inclined in the same direction. The deflector elements of at least two immediately adjacent first rows are inclined in the same direction. The mixing element is used in an exhaust system of an internal combustion engine.

Abstract: The invention relates to an improved red light emitting material of the formula M1?yA1+xSi4?xN7?x?2yOx+2y:RE whereby M is selected out of the group comprising Ba, Sr, Ca, Mg or mixtures thereof, A is selected out of the group comprising Al, Ga, B or mixtures thereof, RE is selected out of the group comprising rare earth metals, Y, La, Sc or mixtures thereof and x is ?0 and ?1 and y is ?0 and ?0.2. This material is believed to crystallize in a novel structure type that comprises two individual lattice sites for rare earth metal incorporation, which leads to an improved lighting behaviour.
