Abstract: Catalytic distillation reactions are improved by having an inert condensing component present in the reaction which is boiling and condensing within the reaction which washes the catalyst in the system and, in the case of gaseous reactants, occludes a portion of the reactants to facilitate the reaction without unduly high pressures. The iner t condensing component is boiling at the conditions within the reactor and is taken overhead for condensation and return as reflux. The ine rt condensing component may occlude the gaseous reactants allowing for better contact with the catalyst and provides the benefits of concurrent reaction and distillation, for example, the reaction of CO and H2 over a copper catalyst to produce methanol using propane as the inert condensing component.

Abstract: The present invention relates to a data communications network and a method for operating the data communications network, wherein the data communications network essentially consists of fixed stations on or near the ground and freely movable flying objects, which are linked together by means of wireless data links. The concept of the invention is based on interruption-free optical laser communications between various flying objects, which typically operate above the cloud tops. These laser-optical data links offer the greatest degree of interception security, and in addition can be advantageously built up or changed very rapidly.   Since the individual flying objects operate independently of each other over a wide range, a maximal autonomy of the communications network can be assured. In particular is it possible by means of this to reconfigure the data communications network very rapidly and to adapt it in this way to changed conditions. Moreover, redundancy, and therefore greater flexibility in the topology of the data communications network, can be created by the use of additional flying objects.

Abstract: A call center includes a recording/playback unit for recording audible signals received (during an outgoing call) from a remote party location, while a call classifier unit within the call center processes the audible signals. A  call processing unit places a call to a remote party location via a communication network to attempt to elicit a desired response from the remote party. The call classifier then processes audible signals received from the remote party location to determine whether or not the call was answered by a live party. The audible signals are recorded by the recording/playback unit and are placed in a queue while the call classifier processes the audible signals. If the call classifier determines that the call was answered by a live party, the call processing unit completes a path between the recording/playback unit and a local agent at the call center, and the recorded audible signals from the remote party are played back to the agent in an accelerated fashion. Meanwhile, the queue is being filled with incoming audible signals at normal speed. Once the queue of recorded audible signals has been emptied, the call processing unit establishes a realtime path between the remote party location and the local agent. If the call classifier determines that the call was not answered by a live party, the call processing unit will terminate the call.

Abstract: La présente invention concerne un procédé de détection des variations de nucléotides dans un premier acide nucléique. Ce procédé consiste à générer un ensemble de produits d'extension à un seul brin à partir d'un premier acide nucléique en présence de bases de nucléotides modifiées, selon lequel les produits d'extension comprennent des nucléotides modifiés, ce qui limite l'activité de l'exonucléase à la base des nucléotides à terminaison 3', et selon lequel les produits d'extension présentent des longueurs variables. Ce procédé consiste ensuite à hybrider les produits d'extension de longueur variable à un acide nucléique de référence, à placer les acides nucléiques en cours d'hybridation en contact avec une enzyme qui peut enlever et remplacer le nucléotide à terminaison 3' des produits d'extension en présence de nucléotides marqués sélectionnés, les produits d'extension qui se terminent avec un nucléotide-3' qui ne s'hydride pas avec la position correspondante sur l'acide nucléique de référence sont remplacés par un ou plusieurs nucléotides qui s'hybrident avec les nucléotides correspondant sur l'acide nucléique de référence, et -es produits d'extension qui présentaient un nucléotide sans hybridation au niveau de la terminaison 3' peuvent maintenant être différenciés de ceux qui possédaient un nucléotide en cours d'hybridation au niveau de la terminaison 3'. Ce procédé consiste ensuite à distinguer les produits d'extension possédant un nucléotide ne s'hybridant pas au niveau de la terminaison 3' de ceux possédant un nucléotide s'hydridant au niveau de cette même terminaison 3', ce qui permet de détecter la variation des nucléotides dans le premier acide nucléique. D'autres modes de réalisation du procédé sont également décrits, qui permettent de détecter aussi des mutations dans un acide nucléique au niveau de la pénultième position terminale 3' sur les produits d'extension à un seul brin.
