摘要: The invention relates to a single-part, biocompatible hip-joint socket moorable without cement, which hip-joint socket can be used universally in combination with hip-joint endoprostheses and is especially suitable for the treatment of dysphasia hips. The joint socket is made of Ti or Ta metals forming a barrier layer or of alloys thereof and is provided with a perforated flange ring for screwing to the pelvic bone, as well as being provided over its entire surface with specific function characteristic oxide layers containing bioactivators. For the implantation of the hip-joint socket, there are not required any special operating instructions, and additional operations, such as pelvic osteotomies, plasties of the roof of the acetabulum and repeated operations are prevented or minimized.

摘要: A ceramic-coated metal implant is used in medicine as a hemiprosthesis or endoprosthesis. A metal implant base body having at least a surface comprised of a barrier layer metal is imparted with a surface roughness of 100-400 .mu.m by means of a mechanical and/or chemical and/or electrochemical pretreatment, thereby increasing the effective surface by more than 400%. Using anodic oxidation through spark discharge in aqueous electrolytes, an outer thickness of the roughened barrier layer metal is converted into a ceramic layer comprising oxides of the barrie layer metal and, optionally, a resorbable calcium phosphate. A maximum amount of calcium phosphate ceramic in the oxide layer faces an implantation bed of the implant. The calcium phosphate ceramic concentration decreases in the direction towards the phase boundary of the base body and oxide layer, so that bone can grow into the ceramic-coated metal implant and attain a high tenacity. In order to attain characteristics which are specific to bone, an after treatment in specific media, such as, for example, amino acids or antibiotics, can be performed. The implant can remain in place for a long period, is highly compatible with tissue and provides a large surface of bone contact, which automatically regulates bone growth in accordance with healing and growth processes.

摘要: The invention relates to a method of producing epoxy resins from hydrocarbons with olefinic double bonds, especially alkenes, by heterogeneous catalyzed oxidation in the gaseous phase. According to said method, and oxidic solid catalyst is released which contains iron as its active component at a concentration of 0.001-1% and alkali and/or alkaline earth elements as the promoters. N2O is used as the oxidizing agent. The granulated oxidic solid catalyst, especially on the basis of SiO2 as the carrier, has a specific surface of greater that 50 m2/g. The ratio of the concentrations of the active components to the promoter components is preferably between 1:100 and 10:1. The partial oxidation of hydrocarbons with olefinic double bonds, especially propene, results in propene selectivities of 10-70% at reaction temperatures of 300-500° C. and conversions of 2-30%. The catalyst repeatedly used in the reaction process can easily be regenerated by oxidation in air so that it retains its high activity even after 50 or more regeneration cycles.
