Patent CA-2322755-A1 (CA)
Title: Network device and information representation using objects
Inventor: LUDTKE HAROLD AARON
IPC: H04L12/24
Filed: 1999-03-09
Abstract: Object lists and object entries provide a general hierarchical model for representing functions and capabilities of a network of devices in a uniform standardized format. The object lists and object entries are used to represent devices, subdevices, supported media, installed media and available services. Preferably, the devices are coupled together in an IEEE 1394-1995 serial bus network. The list of devices within the network are included within a unit object list, including unit object descriptors each representing a corresponding device. For devices having subunits, the unit object descriptor is associated with a subunit object list, including subunit object descriptors each representing a corresponding subunit within the device. Each subunit object descriptor then also has associated object lists, as appropriate, including a supported media object list including entries representing types of media supported by the subunit and an installed media object list including entries representing information available on the media currently installed within the subunit. For subunits capable of providing services, the subunit object descriptor has an associated object list, including an available services list including entries representing the services currently available through the subunit. The uniform standardized format of the object lists and object entries of the present invention allow two devices coupled together within the IEEE 1394-1995 serial bus network to exchange information including their respective object lists and entries.

Title: Systeme de securite et de perennite de couche optique
Inventor: MONMA CLYDE
IPC: H04B10/85
Filed: 2000-01-25
Abstract: L'invention se rapporte à une technique d'en-tête de signalisation optique applicable à des réseaux optiques, selon laquelle des informations d'acheminement des paquets sont transportées sur le même canal ou à la même longueur d'onde que la charge de données de sorte que l'en-tête et la charge de données se propagent dans les éléments du réseau sur le même chemin et avec les mêmes temps de propagation associés. Cette technique entraîne la pérennité et la sécurité des réseaux optiques du fait qu'elle superpose à la sécurité (121-123) électronique classique une couche (131-133) de sécurité optique grâce à la génération de versions dupliquées de la charge de données d'entrée au niveau du noeud d'entrée, et à l'émission de chacune des versions dupliquées sur une des liaisons correspondantes de l'ensemble des liaisons. De plus, chacune des liaisons est composée de multiples longueurs d'onde de manière à propager les signaux optiques ou les paquets optiques, et chacune des versions dupliquées de la charge de données peut se propager à une longueur d'onde sélectionnée parmi les longueurs d'onde de chacune des liaisons correspondantes de l'ensemble des liaisons.

Title: Method for preparing aminonitrile and diamine
Inventor: LECONTE PHILIPPE
IPC: C07C255/24
Filed: 1999-05-11
Abstract: The invention concerns a method for preparing aminonitrile and diamine by catalytic hydrogenating dinitrile. It consists of a method for preparing aminonitrile and diamine by catalytic hydrogenating aliphatic dinitrile having 3 to 12 carbon atoms, characterised in that the final reaction mixture, from which the catalyst has been previously separated, is acidified by adding a sufficient amount of a mineral or organic acid before it is subjected to an operation distilling the reaction products and the non-transformed dinitrile. The invention more particularly concerns the preparation of amino-6-capronitrile and hexamethylenediamine by hydrogenating adiponitrile. The amino-6-capronitrile can be hydrolysed in liquid phase or gaseous phase to lead to caprolactame. The hexamethylenediamine can be used in particular for preparing polyamide-66 by reaction with adipic acid.

Title: Carbonyl-stress improving agent and peritoneal dialysate
Inventor: MIYATA TOSHIO
IPC: A61M1/28
Filed: 1999-08-23
Abstract: Drugs for relieving carbonyl stress in the peritoneal cavity to be used in peritoneal dialysates which contain carbonyl compound-trapping agents as the  active ingredient. Carbonyl compounds formed and accumulated during peritone al dialysis are inactivated or eliminated by carbonyl compound-trapping agents such as aminoguanidine. Carbonyl compounds formed during the sterilization a nd storage of peritoneal dialysates are eliminated by preliminarily bringing in to contact with the trapping agents. Further, addition of the trapping agents t o peritoneal dialysates or circulation of the trapping agents by using a cartridge for trapping carbonyl compounds makes it possible to eliminate carbonyl compounds originating in the blood of the patients which flow into the peritoneal cavity as the dialysis proceeds. Thus, modification of protei ns in the peritoneal cavity can be inhibited and peritoneal damage in associati on with peritoneal dialysis can be relieved.
