Title: Preventing conflicts in distributed systems
Inventor: GEHANI NARAIN H
IPC: G06F17/30
Filed: 1997-05-20
Abstract: A token-based protocol used to prevent conflicts between copies of the same data items residing in different servers of a replicated distributed system is provided. The servers in the system with database replicas are provided with token pointers that are each associated with a token. Token pointers are used to track the current possessor of the token. Whenever a server receives or transfers a token, its corresponding token pointer is updated to reflect which server possesses the token. The use of token pointers advantageously eliminates the need for global cooperation by the servers to regenerate a lost token.

Title: Uv radiation process for making electronic devices having low-leakage-current and low-polarization fatigue
Inventor: AZUMA MASAMICHI
IPC: C23C16/48
Filed: 1996-03-14
Abstract: A precursor solution (P22) formed of a liquid polyoxyalkylated metal complex in a solvent is applied to a substrate in the formation of a metal oxide thin film (P26). The liquid thin film is baked (P28) in air to a temperature up to 500 ~C while UV radiation having a wavelength ranging from 180 nm to 300 nm is applied. The thin film can be twice-baked at increasing temperatures while UV  radiation is applied at one or both bakings. The film is then annealed (P32) at temperature ranging from about 700 ~C to 850 ~C to produce a thin-film solid metal oxide product. Alternatively, the UV radiation may be applied to the liquid precursor, the thin film may be annealed with UV radiation, or combinations of such applications of UV radiation to the precursor, to the thin film before or after baking, and/or UV annealing may be used.

Filed: 1996-04-03
Abstract: Des cellules de mammifères sont modifiées génétiquement par introduction de gènes codant des protéines à régulation négative du complexe majeur d'histocompatibilité (CMH) issues de virus. Les cellules appropriées pour une transplantation sont prélevées sur un donneur puis transfectées par un vecteur d'expression codant une ou plusieurs protéines à régulation négative du CMH issues de virus. Les cellules du donneur génétiquement modifiées sont développées ex vivo, lorsque cela se révêle nécessaire, puis transplantées sur le récepteur. Les taux plus faibles de protéines de classe I du CMH permettent aux cellules transplantées de survivre dans des conditions où des cellules non modifiées génétiquement feraient l'objet d'une offensive du système immunitaire du récepteur. Les cellules du donneur peuvent en outre être modifiées pour cibler des cellules ou pour renforcer la fonction effectrice des cellules du donneur chez le récepteur.

Patent CA-2219779-A1 (CA)
Title: Hydrostatic shear inducing short dwell coater
Inventor: WAECH THEODORE G
IPC: D21H23/00
Filed: 1996-03-15
Abstract: A coater head (22) has a housing (23) which defines a coating pond (28) supplied with coating under pressure. A plurality of bars (21) extend within the coating pond (28) in the cross-machine direction, and are spaced parallel to one another in the machine direction. A paper web (36) is engaged against a backing roll (24), and travels through the coating pond (28) past a metering blade (30) which applies coating from the pond to the web. The bars (21) induce a turbulent flow which shears bubbles of air entrained in the coating pond, thereby reducing the bubble diameters and air-induced imperfections in the coating. Greater machine speed, which tends to entrain more air, induces greater shear at the bars which causes bubble size to be more greatly reduced.
Patent CA-2221467-A1 (CA)
Inventor: SMITH CASSANDRA L
IPC: C12Q1/68
Filed: 1996-05-20
Abstract: Cette invention se rapporte à des procédés permettant la détermination rapide de la séquence de base et/ou de la longueur d'une séquence cible. Cette séquence cible peut être constituée d'une série de séquences répétitives connues ou inconnues qui sont hybridées à un ensemble de sondes. L'ensemble hybridé est digéré avec une nucléase simple brin et des groupes libres 3'-hydroxyle allongés par une polymérase d'acides nucléiques. On peut facilement différencier les éléments hétéroduplex coupés de nucléase des éléments hétéroduplex non coupés de nucléase au moyen d'un marquage différentiel. Les sondes et la cible peuvent être marquées différemment avec des marqueurs détectables. On peut détecter la cible concordante en coupant de la cible hybridée les boucles résultantes et en créant des groupes libres 3-hydroxyle. Ces groupes sont reconnus et allongés par des polymérases ajoutées au système réactif qui ajoute également ou libère un marqueur à l'intérieur de la solution. L'analyse des produits résultants est effectuée au moyen d'une phase solide ou d'une solution. Ces procédés peuvent servir à la détection de séquences d'acides nucléiques caractéristiques, à la détermination de la séquence cible et à la recherche de malformations ou de troubles génétiques. Il est possible d'effectuer des essais sur des surfaces solides, ce qui permet le déroulement de multiples réactions en parallèle, et si cela est souhaité, il est possible d'automatiser ces essais.

Inventor: SIKKEMA DOETZE JAKOB
IPC: C07C65/05
Filed: 1996-10-21
Abstract: Described is a process for dicarboxylating dihydric phenols, notably those where the hydroxyl groups are in the para- or the ortho-position vis-à-vis one another. More particularly, the invention pertains to a process for preparing 2,5-dihydroxyterephthalic acid (2,5 DHTA).
