In a direct drill bit drive for tools for comminuting brittle materials and penetrating into brittle materials by percussive impact on the basis of a heat engine operated with a gaseous working medium, the heat engine is a hot gas engine operating in accordance with a real Stirling cycle process.

Direct drill bit drive for tools on the basis of a heat engine

The invention relates to a novel family of oligomeric and polymeric s-triazine and s-heptazine derivatives and to their use as an intermediate, e.g. as precursors for producing Si/(M)/C/N/(O) ceramics, as mesoporous materials such as, e.g., catalyst carriers for storing gas or as a stationary phase for chromatography, as flameproofing agents, plastic additives or for other organic/inorganic functional materials.

Silicon- and polysilyl cyamelurates as well as -cyanurates, methods for the production thereof and their use

The present invention relates to unsymmetrical and symmetrical phosphorus-comprising heptazine derivatives, represented by the formula (1): in which R, Rand Rare, independently of one another, an azide group &#x2014;Nor an &#x2014;N&#x2550;PRRRgroup, with the proviso that at least one radical from R, Rand Ris an &#x2014;N&#x2550;PRRRgroup, to a process for the preparation thereof and to the use thereof.
