| 20080235473 | PROTECTION UNIT FOR A PROGRAMMABLE DATA-PROCESSING SYSTEM - A data-processing system having at least one operating memory holding operating data is provided with a protection unit having an execution environment protected from unauthorized access. At least one monitoring logic in the execution environment is connected to the operating memory for monitoring unauthorized modifications, access, or similar protection violations of the operating data stored in the operating memory and for generating an output on detection of such a protection violation. A protection logic in the execution environment holds replacement data capable of replacing the operating data and is connected to the monitoring logic for, on generation of the output, providing to the operating memory the replacement data for the operation or for a substitute operation of the data-processing system. | 09-25-2008 |
| 20090036702 | PRODUCTION OF ORGANOSILANES IN THE PRESENCE OF IRIDIUM-CATALYSTS AND COCATALYSTS - Organosilanes are prepared efficiently by hydrosilylation of an alkene in the presence of iridium compounds as catalysts and an inorganic, metal organic, or organic oxidant as cocatalyst. side reactions and catalyst deactivation are thereby minimized. | 02-05-2009 |
| 20090286899 | PLATINUM CATALYSTS SUPPORTED ON NANOSIZE TITANIUM DIOXIDE, THEIR USE IN HYDROSILYLATION AND COMPOSITIONS COMPRISING SUCH CATALYSTS - Nanosize titanium dioxide having supported thereon metallic platinum are efficient hydrosilylation catalysts whose hydrosilylation activity may be increased by irradiation. The catalysts are prepared by depositing soluble platinum compounds on a titanium dioxide sol or titanium dioxide pigments followed by drying, calcining, and reduction to platinum metal. The catalysts are particularly useful in preparing addition-curable organopolysiloxane elastomers. | 11-19-2009 |
