Patent CA-2221517-C (CA)
Inventor: NG SIMON
IPC: C07K14/00
Filed: 1996-06-04
Granted: 2008-11-18
Abstract: La présente invention se rapporte à un procédé en phase solide pour la synthèse d'oligomères N-substitués, tels que les poly(glycines N substitués) (ci-après désignées comme poly NSG). Ce procédé est utilisé pour obtenir des oligomères, tels que les poly NSG présentant un intérêt thérapeutique. Ces poly NSG peuvent comporter une grande variété de substituants à chaîne latérale. Chaque monomère de glycine N-substitué est assemblé directement sur le support solide à partir de deux "sous-monomères". Chaque cycle d'addition de monomère comprend deux étapes: (1) l'acylation d'une amine secondaire liée au support avec un agent d'acylation comportant un groupe partant susceptible d'effectuer un déplacement nucléophile par -NHJ2, tel qu'un acide haloacétique, et (2) l'introduction de la chaîne latérale par le déplacement nucléophile du groupe partant, tel qu'un halogène (en tant que  alpha -haloacétamide lié au support solide) avec une quantité suffisante d'un second sous-monomère comportant un groupe -NH2, tel qu'une amine primaire, une alkoxyamine, un semicarbazide, un hydrazide acyle, un carbazate ou autres composés similaires. La répétition du cycle à deux étapes d'acylation et de déplacement permet d'obtenir les oligomères souhaités. La présente invention décrit également des bibliothèques combinatoires de composés cycliques, dans lesquelles les composés cycliques comprennent au moins une structure d'anneau dérivée de la cyclisation d'un squelette peptoïde. La variété de composés de produit est générée par l'addition séquentielle de sous-monomères substitués. L'invention décrit également des procédés pour synthétiser les bibliothèques combinatoires ainsi que les dispositifs de dosage produits à l'aide des bibliothèques, tout comme la méthodologie permettant de trier et d'obtenir des composés organiques cycliques bioactifs.

Title: Optically enhanced dual liquid crystal display backlight
Inventor: BERNARD EDWIN I
IPC: G02F1/13357
Filed: 1998-06-01
Granted: 2004-12-28
Abstract: Light emitting devices are combined with non-imaging optical elements to create a backlighting system for liquid-crystal displays (LCDs). A pair of optically isolated sub-systems, a night vision imaging system (NVIS) (14) and a daylight system (12) are combined to provide optimum display legibility in ambient illuminations ranging from bright sunlight to total darkness. The sub-systems utilize non-imaging optics based upon total internal reflection (TIR) and light reflection, both coupled to a light emitting source, such as fluorescent tubes (34) and other linearly shaped light sources. Light reflectors (32) are shaped to concentrate light onto non-imaging optics lens (30) so as to compensate for non-linear characteristics of the TIR lenses.

Title: Bidding for telecommunications traffic
Inventor: COYLE WILLIAM F
IPC: H04Q3/00
Filed: 1996-10-31
Granted: 2001-01-09
Abstract: Telecommunication switches (e.g., PBX's or local exchange carrier's switches) route calls in accordance with economic icentives (e.g., least cost routing) resulting from a bidding process between participating interexchange telecommunication carriers (Carriers) by operation of a central processor, a computer referred to as a bidding moderator (Moderator). Each of the Carriers informs (28) the Moderator of the rate it is willing to charge (or other economic incentive it is willing to offer) for service between two specific points in the telecommunication network at some particular time. The Moderator collects this bid information (20) from all the Carriers, sorts it among originating points (22) and transmits (23) it to an adjunct processor at each subscribing switch location and to all participating Carriers' network management centers (21). From the list of all Carriers providing bid information to the Moderator, each Subscriber can select those Carriers to which it wants traffic routed and can change that selection at any time. After each new bid is submitted (28) by a Carrier and is processed by the Moderator (22), it is distributed to both the relevant Subscribers (23) and all other Carriers (21). All Carriers have the opportunity to submit (27, 28) at any time a lower or higher bid for any point-to-point routes on which they wish, respectively, to stimulate or discourage additional traffic. The Moderator could offer a different class of service to end users who are calling parties by broadcasting each carrier's bid to an interface unit at each user location.

Abstract: Ce tube de ligne de transmission de signal de déclenchement (10a, 10b, 10', etc.), qui transmet efficacement un signal de déclenchement le traversant, comprend au moins une ligne de rupture (20a, 20b, 20c, etc.) dans la paroi du tube. Ces lignes de rupture (20a, 20b, 20c, etc.), qui peuvent être des cordons de soudure et/ou des rainures, sont rompues par le passage du signal de déclenchement. La carcasse du tube épuisé est divisée ou fragmentée, de sorte que de telles carcasses constituent des déchets moins encombrants que les carcasses de tube de choc intactes sur un site de travail. Si le tube est extrudé, une ligne de rupture peut être formée par mise en contact de la paraison (18) à partir de laquelle le tube est réalisé avec un moyen de formation d'entailles tel qu'une pointe ou une lame (124a, 124b). Eventuellement, le moyen de formation d'entailles peut être déplacé radialement pendant le processus d'extrusion pour produire des lignes de rupture en serpentins ou hélicoïdales. Les lignes de rupture se coupent de préférence périodiquement et, lors de l'allumage, le tube se fragmente en éclats. Dans une variante, le tube (50d) peut être extrudé en segments (62) qui adhèrent entre eux au niveau d'interfaces (64) qui constituent des lignes de rupture sur le tube. Eventuellement, certains segments (62) peuvent être formés à partir de matériaux extrudés différents des autres segments.
