Abstract: A composition contains glycolipids and triethyl citrate (TEC). The TEC can assist in stabilizing a foam of a corresponding aqueous composition. A method can be used for preparing a corresponding formulation, preferably a cosmetical or pharmaceutical formulation, by providing the composition and diluting the composition. The pH of the composition may be adjusted during the dilution by adding an organic or inorganic base.

Abstract: A combustion machine comprising an internal combustion engine and a cooling system that has a coolant pump, a main cooler, a heating heat exchanger, a bypass which bypasses the heating heat exchanger, coolant ducts in the internal combustion engine, and a regulating device with an actuator which serves for the regulated distribution of a coolant as a function of at least one local coolant temperature. The invention is characterized in that, when the actuator is actuated in one direction, the regulating device—when it is in a first position, allows coolant flow through the internal combustion engine and the heating heat exchanger, and prevents coolant from flowing through the bypass and the main cooler;—when it is in a second position, additionally allows coolant to flow through the bypass; and—when it is in a third position, additionally allows coolant to flow through the main cooler.

Abstract: The invention relates to an exhaust-gas treatment device (10), comprising a) an outer tube (14) through which an exhaust-gas stream (12) can flow, b) an inner tube (20) that is arranged in a first section (16) of the outer tube (14) and that divides the interior of the first section (16) into a central flow path (22) and a peripheral flow path (24), whereby a first exhaust-gas treatment means (26) is arranged in the central flow path (22) and/or in the peripheral flow path (24), c) means (30, 32) to selectively convey an exhaust-gas stream via the central flow path (22) and/or via the peripheral flow path (24), and d) a second exhaust-gas treatment means arranged in a second section (18) of the outer tube (14) downstream from the first section (16).

Abstract: The invention relates to an exhaust gas cleaning device (10) comprising a) a housing (14) through which an exhaust gas flow (12) can flow; b) an exhaust gas cleaning component (16) that is arranged in the housing (14), which component comprises a carrier (20) which has an end face (22, 24) on the inlet side and on the outlet side and through which the exhaust gas flow (12) can flow; c) at least one separation element (26, 40) that is arranged upstream of the exhaust gas cleaning component (16), which separation element separates an exhaust gas flow path into at least two parallel flow paths (28, 30); and d) at least one sealing means (38, 42) provided in the region of the end face (22) on the inlet side of the carrier (20) and/or of a downstream end of the separation element (26, 40), and that is suitable to counteract a cross flow of the exhaust flow (12) between the at least two parallel flow paths (28, 30).

Abstract: A configuration for sealing-off two fluid-carrying subassemblies, in particular for sealing-off a case, the inner space of which is filled with a first fluid and through the inner space of which there is led a pipeline filled with another fluid which flows into a construction space that is separated from the inner space filled with the first fluid by a case wall. Between a first sealing element and a second sealing element there is disposed a supporting ring, which, on each of its side faces assigned to the sealing elements, has a contour for the reception and diversion of a fluid volume which has flowed onto the supporting ring as a result of leakage in the region of the respectively assigned sealing element.
