Abstract: Des programmes audiovisuels sont transmis sur un réseau à faible bande passante sous une forme compressée dans lequel le nombre d'images vidéo a été réduit en sélectionnant images « significatives ». L'utilisateur voit une série d'images fixes accompagnant un canal audio apparemment complet. Les images sont téléchargées à l'utilisateur dans un ordre visant à assurer, en premier lieu, que les prochaines images nécessaires pour la visualisation sont présentes, mais aussi pour que l'utilisateur puisse faire défiler à travers le programme même si en cours de téléchargement. Ceci est réalisé en téléchargeant tout d'abord l'audio complet pour la partie de programme demandée par le logiciel de visualisation de l'utilisateur, et ensuite en téléchargeant les images vidéo sur la base de demandes provenant du logiciel de visualisation, qui a accès à une table indiquant quelles images vidéo sont associées à quelles parties audio. Le logiciel utilise la table pour télécharger des images nécessaires immédiatement, ainsi que pour télécharger des images d'avance en fonction de leur importance.

Title: Process for the production of endotropine
Inventor: SCHAUPP ALBERT
IPC: C07D471/04
Filed: 1998-05-21
Granted: 2005-10-25
Abstract: The invention relates to a process for the production of endotropine by reducing tropanone with hydrogen catalytically activated by Raney nickel or Raney copper. The prior art processes known from US patents 2,366,760 and 2,746,976 use an overpressure and organic solvents, so that there is a high fire and explosion risk when working up the reaction batch. This problem is obviated by the invention in that the tropanone, in aqueous solution with hydrogen, in a closed system, at atmospheric pressure and ambient temperature, is subject to turbulent action at 1000 to 1500 r.p.m. The process according to the invention leads to average yields of 94%.
