Patent DE-4207379-A1 (DE)
Inventor: ERNST PETER DR
IPC: C22C33/02
Filed: 1992-03-09
Abstract: A process is suitable for producing a sintered body made of a high alloy steel powder. The steel powder is heated up to the sintering temperature, is maintained at the sintering temperature during a predetermined time period and the thus obtained sintered body is then cooled down. This process allows a high density (d) sintered body having favourable mechanical and chemical properties to be produced at temperatures as low as possible, in particular in a temperature range extending up to 600  DEG C. For that purpose, elementary boron or a boron compound is added as a sintering adjuvant to a martensitic steel powder and the added boron is uniformly mixed with the steel powder before sintering.

Abstract: The present invention relates to an environmentally compatible method for precleaning, sterilising, preserving, and for improving the serviceability of, materials to be employed in difficult environments involving strict requirements regarding purity and sterility, these steps to be carried out in a single procedure employing a high-energy compressed fluid. At least one compressed fluid is mixed with at least one physical or chemical agent and at the same time is exposed to an inhomogeneous ionising field and high-energy sound waves, in order to remove, in a process referred to as acoustic-electrolytic extraction, deeply embedded impurities and contaminants from internal and external surfaces of complexly arranged or composite substrates (80), such as e.g. biomaterials, surgical instruments or dental implants. Then the cleaned substrates (80) are exposed to a high-energy oxidative environment in a compressed fluid, in order to ensure deep penetration into the substrate (80) and sterilisation thereof, as well as the removal of biological contamination. Finally, the substrates (80) thus cleaned and sterilised are implanted with chemical agents by means of an acoustic deposition method, in order to ... long-term preservation or novel or improved material properties such as e.g. an improved electrical insulation capacity, increased electrical conductivity ...

Title: Porous film for various applications, produced by spraying
Inventor: KEPPELER MANFRED
IPC: G03C11/12
Filed: 1993-04-21
Abstract: Porous film for various applications, produced by spraying, according to Patent Application P 4134704.8-45 (main application). By spraying, a film which has pores can be produced from any adequately dilutable paint or polymer solution. The term solution is to be understood in the broadest sense, and thus also comprises dispersions, emulsions and the like and their mixtures. Accordingly, organic and/or inorganic solvents, including water, can be used in order to bring the polymers into a sprayable form. Particularly environmentally friendly production is achieved by spraying a dispersion for instance onto glass, ceramic, steel, teflon, polyethylene or other adequately smooth primary carriers, the surface of which has repelling properties. Generating the film by spraying makes a large number of modifications possible in a simple way, such as for instance very thin, uniformly open-pored films, films with small, closed pores or thicker films with large, open pores. Furthermore, it is possible in a simple way to apply barrier or colour layers, copyable, extremely hard, flexible and/or conductive layers. If the film is adhesively attached, film, adhesive and permanent carrier can form a single-material/recyclable composition. Moreover, with identical or similar properties of the components, the adhesive strength and durability of an adhesive bond are considerably improved. As well as good printing, ...
