Title: Compact pressure swing adsorption apparatus
Inventor: BABICKI MATTHEW
IPC: B01D53/06
Filed: 2000-09-25
Granted: 2005-12-13
Abstract: Apparatus for PSA separation of a gas mixture containing a more readily adsorbed component and a less readily adsorbed component, with the more readily adsorbed component being preferentially adsorbed from the feed gas mixture by an adsorbent material under increase of pressure, so as to separate from the gas mixture a heavy product gas enriched in the more readily adsorbed component, and a light product gas enriched in the less readily adsorbed component and depleted in the more readily adsorbed component. The apparatus includes compression machinery cooperating with a number "N" of individual adsorbers or "adsorber elements" mounted in a rotary PSA module, where "N" is a factorable integer. A process for pressure swing adsorption separation is also provided.
Patent CA-2330780-C (CA)
Inventor: DAVIES STEPHEN WILLIAM
IPC: H04L12/56
Filed: 2001-01-10
Granted: 2004-07-06
Abstract: The penalties associated with relying on layer-4 to handle packets lost as a result of a handoff can be reduced by forwarding, in response to a handoff request from a first base station to a second base station, at least one layer-2 frame of a layer-3 packet destined to/from the wireless terminal that has been passed down from layer-3 to layer-2, and so is indicated to have been transmitted at layer- 3 even though not all of the layer-2 frames of the layer-3 packet have actually been transmitted. In one embodiment of the invention, each of the at least one layer-2 frames may be encapsulated together in a special layer-3 packet that is transferred from the first base to the second base station in the usual manner of inter- base- station communication. Advantageously, packets are not lost at layer-4 due to handoffs. Thus, layer-4 retransmissions are not required, and so delays in the network are reduced. Furthermore, if only the layer-2 frames that were not transmitted over the air to the wireless terminal by the first base station are transferred to the second base station, a savings may be had in use of the air interface.

Title: Systeme pour minimiser le potentiel explosif des tourelles amarrees de navires de stockage d'hydrocarbures
Inventor: YETMAN RICHARD D
IPC: B63B21/50

Granted: 2002-11-19
Abstract: L'invention concerne un système destiné au raccordement d'une bouée détachable maintenue par chaînes (24) à une tourelle interne (14) d'un navire flottant de stockage et de déchargement de produits. Des colonnes montantes (30) venant de puits sous-marins sont reliées au moyen de dispositifs de raccord rapide (38) à des tuyaux (36) traversant la tourelle (14) puis, à travers une tête d'injection pour produits (100), aux conduites menant vers les réservoirs de stockage sur le navire. Une structure délimite un espace clos (46) qui renferme les dispositifs de raccord rapide (38) au sommet de la bouée maintenue par chaînes (24). Un puits de ventilation (52) mène de l'espace clos à l'atmosphère en passant par le haut de la tourelle (14). Pendant le fonctionnement normal, une conduite d'air comprimé (48) qui mène jusqu'à l'espace clos (46) sert à ventiler cet espace à travers le puits de ventilation (52). Si une fuite de gaz est détectée dans l'espace clos (46), la ligne d'air comprimé est fermée. Le volume réduit entourant les dispositifs de raccord se remplit rapidement de gaz d'hydrocarbures afin de créer dans l'espace clos (46) un rapport élevé gaz/air et de limiter fortement le danger d'explosion.
Patent CA-2331225-C (CA)
Title: Uplink timing synchronization and access control for a multi-access wireless communication system
Inventor: UPPALA SATHYADEV VENKATA
IPC: H04B7/26
Filed: 2001-01-12
Granted: 2005-11-01
Abstract: Improved timing synchronization and access control techniques for use in an orthogonal frequency division multiplexed (OFDM) wireless system or other type of wireless communication system. In accordance with the invention, an uplink synchronization and access control system is provided in which mobile stations transmit certain timing and access signals in dedicated intervals in an uplink stream. Access control is illustratively implemented as a two-stage process in which a given mobile first transmits a generic uplink access signal in one of the intervals. If this access is accepted, the base station transmits an access acknowledgment containing initial timing and power corrections, along with initial channel assignments on which the mobile can initiate a call set-up process. For re-synchronization, mobiles transmit timing synchronization signals in the dedicated timing and access intervals. The base station measures the arrival time of the signals, and sends back appropriate timing corrections. The invention thereby ensures that orthogonality between mobiles is maintained.

Title: An autopoietic network system endowed with distributed artificial intelligence for the supply of high volume high-speed multimedia telesthesia, telemetry, telekinesis, telepresence, telemanagement, telecommunications, and data processing services
Inventor: ARNOUX LOUIS AUGUSTE
IPC: G06F19/00
Filed: 1999-05-21
Granted: 2009-08-11
Abstract: An autopoietic network is described. The invention is implemented by means of a non-hierarchical network having a fractal structure. The system and its constituent networks are structurally coupled with their environment through hermeneutic processes. The system includes a number of cybernetic devices which are adapted to function as both the infrastructure of the network and the means by which the network services are delivered to network users.  These cybernetic devices communicate with other cybernetic devices in such a manner so that the network is in the form of a fractal, non-hierarchical mesh which is self-similar. The cybernetic devices may be particularly adapted to supervise or "mind" one or more other cybernetic devices functioning at a lower level of aggregation or complexity. The supervised cybernetic devices may be clustered or distributed in space and be associated with machines, systems or people.

Granted: 2008-06-03
Abstract: New secondary amines are described which are prepared from inexpensive, commercially available raw materials, are stable at room temperature, and are reactive toward electrophiles. The secondary amines are prepared by the addition of one or more primary amines with one or more male (amide/ester) and fumar (amide/ester) Michael receptors. The above amines can be used as coreactants with aliphatic polyisocyanates for polyurea coatings. The novel secondary amines are also described as particularly useful as part of a two-part liquid pavement marking composition for pavement markings.

Abstract: Provided are methods and compositions for the photodynamic therapy (PDT) of ocular conditions characterized by the presence of unwanted choroidal neovasculature, for example, neovascular age-related macular degeneration. The selectivity and sensitivity of the PDT method can be enhanced by combining the PDT with an anti-angiogenesis factor, for example, angiostatin or endostatin, or with an apoptosis-modulating factor. Furthermore, the selectivity and sensitivity of the PDT may be further enhanced by coupling a targeting moiety to the photosensitizer so as to target the photosensitizer to choroidal neovasculature.
