Title: Chemical reactor with pressure swing adsorption
Inventor: KEEFER BOWIE G
IPC: B01D53/04
Filed: 2000-06-09
Granted: 2010-07-27
Abstract: A chemical reaction is performed with separation of the product(s) and reactant(s) by pressure swing adsorption (PSA), using an apparatus having a plurality of adsorbers cooperating with first and second valve assemblies in a PSA module. The PSA cycle is characterized by multiple intermediate pressure levels between higher and lower presures of the PSA cycle. Gas flows enter or exit the PSA module at the intermediate pressure levels as well as the higher and lower pressure levels, entering from compressor stage(s) or exiting into exhauster or expander stages, under substantially steady conditions of flow and pressure. The PSA module comprises a rotor containing the adsorbers and rotating within a stator, with ported valve faces between the rotor and stator to control the timing of the flows entering or exiting the adsorbers in the rotor. The reaction may be performed within a portion of the rotor containing a catalyst.

Abstract: The illustrative embodiment of the present invention provides a platform that enables a content developer to distribute uniform content to multiple types of requesting mobile devices. By authoring content in a generic markup language and using the technologies includes in the Mobile Content Framework (MCF), the content developer is able to provide content to multiple types devices without providing different versions of the content. The content may be authored originally in the generic markup language or translated from other languages into the generic markup language by the MCF. The MCF exploits the capabilities and accommodates the limitations of different types of wireless devices by converting generic markup language content to device-specific content. The MCF interacts with device registries holding records of the device attributes in order to provide the device-specific content. The MCF handles these issues for current mobile devices while also being extensible for future mobile devices.

Abstract: Les procédés décrits se rapportent à un réseau (200) de diffusion satellite qui transmet des informations de programme en temps réel et des données <= best effort >= (de service dit<= au-mieux >=) àde noeuds (230) de routage multiples à partir d'une source (201). Le noeuds de routage sont conçus spécifiquement pour extraire les flots de données <= best effort >= du signal multiplexé reçu p. ex. via un satellite. L'invention concerne une pluralité de procédés d'administration. Un de ces procédés consiste à former un paquet (150) comprenant un en-tête (152) de couche réseau qui contient une adresse permettant l'acheminement du paquet à sa destination, un second en-tête définissant une syntaxe et une sémantique au moyen desquelles le paquet peut être analysé selon un mode (156) prédéfini, et des données (158) utiles contenant une commande devant être exécutée par le noeud ou chaque noeud (230) auquel le paquet est destiné. Le paquet est transmis à plusieurs reprisesà une pluralité de noeuds, comprenant le(s) noeud(s) à administrer, mais la commande contenue dans un paquet particulier n'est exécutée qu'une seule fois. Dans d'autres procédés, les noeuds (230) sont divisés en groupes. Dans un de ces procédés, un identificateur unique est attribué à chaque groupe, l'identificateur étant inclus dans le paquet qui contient la commande. Le paquet est transmis une seule fois mais tous les noeuds le reçoivent, y compris le groupe de noeuds auquel un identificateur identique a été attribué. Seuls les noeuds du groupe possédant un identificateur identique exécutent la commande. Dans un autre procédé, un noeud (212) administrateur tient à jour une liste des adresses de tous les noeuds d'un groupe, et transmet automatiquement un paquet une seule fois à chaque adresse, permettant ainsi la transmission automatique d'un même paquet à des noeuds multiples.
