Abstract:
A method is provided for producing ammonia (NH3) and introducing the produced ammonia (NH3) into an exhaust gas stream as a reduction means for selectively catalytically reducing nitrogen oxides contained in the exhaust gas stream, which is an exhaust stream generated by the combustion process of a motor, a gas turbine, or a burner. The method comprises feeding dry urea from a supply container in a controlled amount to reactor and subjecting the dry urea in the reactor to a sufficiently rapid thermal treatment such that a gas mixture comprising the reaction products of ammonia (NH3) and isocyanic acid (HCNO) is created. Also, the method comprises immediately catalytically treating the thus produced gas mixture in the presence of water such that the isocyanic acid (HCNO) resulting from the rapid thermal treatment is converted, via quantitative hydrolysis treatment, into ammonia (NH3) and carbon dioxide (CO2).
Abstract:
A device for coupling and decoupling two shafts or other elements of a drive train for transmitting rotations or torques especially to be used as a clutch segment in the field of motorcycle drives is provided. The clutch segment includes two parts one of which comprise troughs or recesses being arranged on a circle and offset by essentially the same angle. The troughs are at least approximately tangentially abutting an inner circle. The troughs linearly extend from their deepest point, beginning with a radius of the inner circle, at an angle towards an edge thereof and turn over towards the edge of a radius. A force application point for applying a force for coupling or decoupling the elements is located at a distance from a rotation axis of the clutch segment.
Abstract:
Disclosed is a rotor (1) for an electric rotor motor, consisting of a rotor bell (2) with a peripheral wall (4) and at least one one-sided rotor base (6) to enclose a stator, in particular as a part of a motor housing with a high IP rating, for example IP54 per DIN/IEC-EN 60034-5. The rotor bell (2) features a heat sink (12) with high heat conductivity that extends through the rotor base (6) in such a way that the motor heat arising on the inside can be removed via the heat sink (12) through the rotor base (6) to the outside into the environment. Further, the invention relates to an electric rotor motor, in particular with an encapsulated motor housing with a high IP-protection system, for example IP54 per DIN/IEC-EN 60034-5, consisting of a stator and a rotor (1) enclosing the stator in an embodiment of the above-described type.

Abstract:
A device for the reduction of nitrogen oxides in the exhaust gas of internal combustion engines has a thermolysis reactor (10). In the thermolysis reactor (10), urea is converted into ammonia and isocyanic acid by means of the supply of heat. In a preferred embodiment of the invention, the thermolysis reactor (10) is arranged within the exhaust gas duct (26) and is thermally coupled to an oxidation catalytic converter (30) which is connected upstream of the thermolysis reactor (10) in the flow direction. As a result of the exothermic reactions taking place in the oxidation catalytic converter (30), it is possible for heating of the thermolysis reactor (10) to take place. In order to further increase the temperature, it is possible for fuel to be injected into the oxidation reactor (30) by means of a fuel supply device. The fuel is burned catalytically in the oxidation catalytic converter (30).
Abstract:
A multi-stage gas generator comprises a housing with an outer wall and also inner walls, at least two combustion chambers filled with at least one propellant charge, one igniter each associated with a propellant charge for the independent activation of each propellant charge, and at least one thermal insulation arrangement between the propellant charges. The arrangement reduces a transport of thermal energy, generated on the ignition of a propellant charge, to the other non-ignited propellant charge to such a high extent that the non-ignited propellant charge remains below its autogenous ignition temperature. Instead of or additionally to the thermal arrangement a cooling arrangement may be provided.
Abstract:
A method for automatic sleeve filling of a winding shaft on roll cutting and winding machines is provided in which, in an exemplified embodiment, in a first step at least two empty winding sleeves are slid onto a free end of a winding shaft so that the winding sleeves are adjacent to one another, in a second step the last winding sleeve slid on by a freely positionable fork piece of a freely programmable draw-off plate along the winding shaft is slid over the winding shaft until the last winding sleeve has reached a predetermined position, in a third step the next-to-last winding sleeve slid on is grasped by tongs freely positionable along the winding shaft and is slid over the winding shaft to the point where in a fourth step the fork piece can dip into the gap produced by the tongs so that the next-to-last winding sleeve is positionable along the winding shaft by the fork piece.
