  • Process for the enantioselective epoxidation of C═C double bonds
    Patent number: 6225482
    Abstract: A process for the enantioselective epoxidation of C═C double bonds and use of the epoxides. The present invention provides a process for the enantioselective epoxidation of compounds of the formula I by means of a diastereomer and enantiomer enriched homopolyamino acid and an oxidizing agent. The epoxides prepared according to the invention are used as intermediates in organic syntheses.

  • Modular video control system
    Patent number: 4700230
    Abstract: A modular video switching system for switching a video signal from one of many video cameras to a video monitor. The system includes one or more individual modules each containing a limited set of input channels. The modules can be cascaded with each other to permit scanning of the video signals from all modules on to a single video monitor. Also provision is made for modular camera controls, requiring only a single control for all cameras, using modular circuitry to rout the control signals to the appropriate camera.
