Abstract: A DC circuit breaking device is provided for interrupting the transmission of direct currents to an electric power system by making external changes to an arc generated upon contacting or separation of contacts in order to rapidly extend and vibrate arc currents. In a self-excited commuting DC circuit breaking device, coils opposed to a fixed and a movable contact are disposed around the outer circumferences of the contacts, and currents flowing through a commutation circuit or the contacts are allowed to flow through the opposed coils so as to apply magnetic fields to the neighborhood of an arc.      This constitution provides the DC circuit breaking device with high performance that it can rapidly extend and vibrate arc currents to thereby interrupt direct currents.

Title: Correlating information between internet and call center environments
Inventor: BROWN SANFORD SAMUEL
IPC: H04M3/51
Filed: 1997-07-29
Granted: 2001-05-22
Abstract: Coordination of information at the network-based level between call centers connectable over a telecommunications network, such as the telephone network, and a packet network, such as the Internet, creates improved integration of and bonding between a customer's interaction with a Web site and with a call center.  Information about the customer and the customer's Web interaction are delivered to the call center agent along with the call, leading to increased productivity and efficiency in call handling as well as improved call routing.     Calls may be routed to existing call centers based upon information from the Web experience, and information from the user's Web interaction is shared with the call center.  Web interaction information is passed to existing call centers using known call center external control methods, such as DNIS signaling. Information about the Web experience may also be "whispered' to the call center agent, and an agent may "push" Web pages for review by the customer.  As a result, customer acquisition and sales tools more powerful than a mere click-to-callback tool can be made available with a combined marketing approach using the Web and call centers.

Abstract: Système et procédé permettant à des émetteurs multiples (400) de partager un seul canal à multiplexage par répartition de code (MRC) ou à accès multiple par différence de code (AMDC) en utilisant des formes d'ondes orthogonales. Un ensemble de codes orthogonaux de découpage en canaux Wi(t) est généré et à chaque émetteur (400) sont attribués des codes orthogonaux de découpage en canaux et des polynômes de pseudo-bruit de façon prédéterminée. Les émetteurs découpent en canaux chaque signal d'utilisateur au moyen d'un code orthogonal de découpage en canaux Wi(t) et étalent chaque signal d'utilisateur au moyen d'un code d'étalement de pseudo-bruit (PN). Chaque émetteur utilise les mêmes codes de PN et les mêmes décalages temporels. De plus, aucun code orthogonal de découpage en canaux n'est attribué à plus d'un émetteur pendant leur période de partage d'un canal MRC. Les signaux d'étalement sont additionnés au niveau de chaque émetteur (404) avant leur transmission en tant que signal composite. Les décalages sont précorrigés dans le temps (406, 510) afin d'assurer un alignement temporel au niveau des récepteurs. Les fréquences des signaux sont précorrigées (408, 512) afin d'assurer l'alignement de fréquence au niveau des récepteurs.

Title: Machine for synthesizing oligonucleotides
Inventor: HOLMBERG LARS
IPC: B01J19/00
Filed: 1996-08-16
Granted: 2008-05-06
Abstract: A machine (8) for synthesizing oligonucleotides has individual pumping modules for connection to each of a number of different monomers and to other fluids used in the synthesizing process. Each pumping module includes a pump (50-59) and a three-port/three-way valve (30-39) with the first inlet port connected to receive the fluid, and the second port connected to receiving a flushing agent, such as acetonitrile. A valving arrangement (98, 102) downstream from the pumping modules selects a monomer. The selected monomer and other fluids pass through flow sensors (110, 112, 114) which provide signals to a controller, which uses these signals to regulate the pumping of the pumps (50-59). At least some of the valves allow multiple inlet ports to be kept open at the same time, thus allowing certain of the liquids to be mixed within the valves. The various pumps, valves and sensors are mounted to the exterior of a cabinet (170) and arranged such that the liquid handling portions are exterior to the cabinet (170), while electrical portions are within the cabinet (170). Air is continuously purged within the cabinet (170) in order to prevent the introduction of solvent fumes near electrical components. The machine (8) can produce up to 100 millimoles of oligonucleotides, and the arrangement provides for the efficient use of materials.
