摘要:
The invention relates to implants that are implanted as temporary implants in living beings and that degrade over a period of time in the body by bioresorption, and to a method for production thereof. The implant according to the invention is composed of magnesium or a magnesium-based alloy. It is formed from fibres of magnesium, or of a magnesium-based alloy, that are interconnected by locally spaced-apart sinter bridges and form an open-pore body. The fibres can be produced by the melt extraction method and then sintered accordingly with one another.

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.

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.
