Title: Methode et appareil pour reduire les deficiences d'un systeme de communication optique
Inventor: DARCIE THOMAS E
IPC: H04B10/572
Filed: 1994-09-21
Abstract: L'invention est constituée par une méthode et un appareil qui réduisent le bruit dans les systèmes de communication optiques en modulant la fréquence de sortie du laser à une cadence relativement peu élevée. La fréquence du laser peut être modulée en appliquant une tension sinusoïdale basse fréquence à l'élément chauffant résistif de la section de commande de phase du laser, ou directement à la section active du laser. En modulant un laser à une fréquence peu élevée et à une amplitude suffisamment élevée pour entraîner de grandes excursions de fréquence dans le signal lumineux, on réduit le bruit dû à la présence d'une multiplicité de trajets sans accroître substantiellement les effets de dispersion nuisibles.

Patent CA-2170418-A1 (CA)
Inventor: IKI NAOHIRO
IPC: H04Q3/54
Filed: 1991-03-28
Abstract: In a reconfigurable communications system, circuit status bits are stored in a first matrix of rows associated respectively with predefined network configurations and columns associated respectively with predefined circuit configurations. Destination status codes are stored in a second matrix of rows associated respectively with the circuit configurations and columns associated respectively with switching nodes of the system. Each circuit configuration comprises one or more transmission links and each circuit status bit stored in each column of the first matrix pattern indicates the presence or absence of the circuit configuration associated with that column. Each destination status code indicates the presence or absence of transmission links from each switching node to possible destination nodes. In response to a manual command, the circuit status bits stored in one of the rows of the first matrix are respectively multiplied with the destination status codes stored in each column of the second matrix, and the multiplied binary values are summed so that network configuration data is derived with respect to a desired network configuration, which is then transmitted to the switching nodes to reconfigure the system.
Patent CA-2172107-A1 (CA)
Title: Shaped lignocellulosic-based activated carbon
Inventor: MILLER JAMES R
IPC: C01B32/384
Filed: 1996-03-19
Abstract: Extruded pellets comprising a majority of activated carbon particles and an inorganic binder are disclosed to provide improved performance when processed through tumbling equipment while the pellets are in their "green" state (i. e. , pellets which are fresh off the extruder'and contain activated carbon), binder material, and water and have not been subjected to any thermal processing (drying or calcining). The tumbling action both smooths and densifies (i. e. , reduces interparticle voids within) the pellet, thereby closing any cracks and greatly improving appearance. Improved performance results from an ability to increase the weight of carbon pellets which can be packed into a fixed volume and thereby increase the volumetric working capacity of the bed for adsorbing/desorbing vapors. Another benefit is to greatly reduce the levels of dust associated with the carbon, both the initial dust and the dust attrition.

Patent CA-2175388-A1 (CA)
Title: Bivalent thrombin inhibitors
Inventor: KONISHI YASUO
IPC: A61K38/00
Filed: 1994-10-25
Abstract: Hirudin is the most potent and specific thrombin inhibitor and is derived from the medicinal leech. It is reported to inhibit thrombin with an equilibrium dissociation constant (Ki) value of 2.2 x 10-14 M. synthetic thrombin inhibitors have been designed based on the hirudin sequence but with a dramatically reduced size. The bulky active site inhibitor segment, hirudin148, has been substituted by small non-substrate type active site inhibitors of thrombin, e.g., dansyl-Arg-(D-pipecolic acid). The linker segment has also been modified using a combination of .omega.-amino acids to reduce the molecular weight but retaining sufficient length to span the two principal binding domains. Among the inhibitors designed, dansyl-Arg-(D-pipecolic acid) (12-aminododecanoic acid) -4-aminobutyric acid) -Asp-Tyr-Glu-Pro-Ile-Pro-Glu-Glu-Ala- (L-.beta.-cyclohexylalamine) - (D-Glu) -OH showed the highest affinity and displays a competitive-type inhibition. The incorporation of the non-substrate type active site inhibitor segment and the linker of .omega.amino acids into the bivalent thrombin inhibitors not only improved in vitro thrombin inhibitory activity to the pM level, overcame proteolytic susceptibility at the level of the "normal" scissile bond and confered high in vivo activity.
