摘要： The invention relates to a device and a method for aftertreatment of exhaust gases from combustion engines, especially internal combustion engines. According to the invention, the device and method should be able to be constructed simply and be run cheaply, without exhaust gas flow characteristics being influenced in a detrimental manner. In order to solve this task, at least one area (3) containing metal balls, preferably hollow metal balls, is incorporated into an engine's exhaust flow stream. The combustion engine's exhaust gases are conducted through said area, thus enabling a simultaneous particle agglomeration and particle separation to take place. In addition to said area, the exhaust gases can be conducted through additional areas (5) filled with metal fibres that can be connected to at least one of the previous areas (3) filled with metal balls.

摘要： The invention relates to hollow balls comprising shells consisting of a sintered inorganic material, such as metals, metal oxides or ceramics. The invention also relates to methods for producing lightweight structural elements by means of such hollow balls. The aim of the invention is to enlarge the field of application, to technologically simplify the treatment for producing structural components and to improve the application characteristics of the hollow balls and the structural components produced therewith. An additional solid functional layer is designed on the hollow balls and on a shell. The material of the functional layer can be formed in a free-flowing, plastic and/or elastic manner owing to a physical and/or chemical treatment.

摘要： The invention relates to the field of mechanical engineering and concerns a thermal radiation shield for vacuum and protective atmosphere furnaces, which is used for effecting a thermal radiation shielding that is a good at possible. The aim of the invention consists in providing thermal radiation protective shields with a reduced weight while having an identical or lower effective emissivity. To this end, the invention provides a thermal radiation protective shield for vacuum and protective atmosphere furnaces that is comprised at least of a porous ceramic and/or metallic material, which comprises, on a surface in the direction of the heat source, high thermal radiation-reflecting properties.

摘要： According to the invention, the shaped bodies are comprised of at least one heavy metal, preferably Fe, Ni, Co, Sn, Mo or W, which can be reduced from a corresponding metal compound at a temperature of less than 1,500 °C. The shaped bodies have an outer diameter ranging from 0.05 to 0.5 mm and a diameter to wall thickness ratio ranging from 0.5 to 3 %. According to the method, starting materials are applied as a covering layer to supporting elements of any shape, and the green products produced in such a manner are subsequently heat-treated. During the heat-treatment, the supporting elements are pyrolyzed, the covering layers are, in essence, thermally decomposed, and the decomposition products are sintered. The outer dimensions of the supporting elements are selected such that they are larger than the shaped bodies to be produced. Metallic compounds, preferably metal oxides, metal hydroxides, metal carbonates, or organometallic compounds are selected as starting materials and can be reduced at a temperature of less than 1,200 °C. The heat treatment is carried out in a reductive atmosphere containing hydrogen and/or carbon in such a way that the starting materials are essentially reduced to the sintered metal which provides the foundation for the respectively used metal compound.

摘要： The invention relates to a sound absorber that can be used to absorb sound waves transmitted by fluids. The aim of the invention is to obtain a high maximum absorption at individual frequencies with high amplitudes, and absorption of sound waves in a spread frequency spectrum, in a simple manner. To this end, the inventive sound absorber is formed, at least in certain areas, from hollow balls that are interconnected in a material fit and/or hollow cones in bulk. Furthermore, regions having different sound speeds, and a characteristic impedance and/or thickness, are adjacently arranged in the flow direction of a fluid, in a laterally successive manner or in relation to sound wave incidence angles.
