Abstract: A pressure vessel includes a carbon fiber reinforced plastic with an integrated permeation barrier as its innermost layer. Alternating layers of permeation barrier and carbon fiber reinforced plastic may also be used. During manufacturing, the permeation barrier is sprayed on and integrated into the composite. The vessel, which is well-suited for high pressure gas storage is lighter weight than prior art vessels and has more usable volume than same-dimensioned prior art vessel. The permeation barrier encapsulates one or more ports or fittings of the vessel to reduce or eliminate the potential for gaps through which gas can escape. In one embodiment, a removable tooling process is employed in the manufacture of the vessel. In another embodiment, a permanent tooling process is employed and the tooling serves as a sorbent material for the vessel.

Abstract: Methods and systems for treating oil sands tailings streams at an elevated pH using lime are disclosed herein. In some embodiments, the method comprises providing a tailings stream including 10-55% solids by total weight, increasing the pH of the tailings stream by combining the tailings stream with lime to produce a lime-tailings mixture having a pH of at least 11.0, and dewatering the lime-tailings mixture to produce a first stream having 10% or less solids by total weight and a second stream having 50% or more solids by total weight. The first stream can correspond to a release water stream, and the second stream can correspond to a cake. The lime slurry can include about 10% lime by total weight, and can comprise lime hydrate, quicklime, or a combination thereof. Dewatering the lime-tailings mixture can include routing the lime-tailings mixture to a centrifuge unit and/or a pressure or vacuum filtration unit.

Abstract: A virtual private network (VPN) service is provided through a shared network infrastructure comprising interconnected provider edge (PE) devices having customer edge (CE) interfaces. Some of the CE interfaces are allocated to a VPN supporting virtual LANs. A correspondence between a CE interface and a virtual LAN is learnt on the basis of tagged frames received at this CE interface and including an identifier of this virtual LAN. The learning process permits the detection of pairs of CE interfaces which correspond to a common virtual LAN. Upon such detection, a virtual circuit is established in the shared network infrastructure between the PE devices having these CE interfaces, and subsequently used for forwarding frames including the identifier of the common virtual VLAN.

Abstract: A method is suitable for processing a plurality of electronic documents designated for processing and delivery to a plurality of recipients, each recipient having a zip code associated therewith. Each electronic document is assigned a plurality of attributes, and the documents are sorted into one or more attribute groups based on the attributes, such that the electronic documents of each attribute group share at least one of the attributes. Output groups are then formed from the electronic documents of each attribute group based on the zip code associated with each electronic document, such that the electronic documents of each output group have similar zip codes. The output groups can then be routed to processing sites for processing the electronic documents to form physical documents for delivery to the recipients.

Abstract: With Reconfigurable Optical Add Drop Modules (ROADMs) gaining popularity in the fiber optic market, many network designers are seeing the benefits of this technology. But the industry standard has been to make ROADMs automatically configurable, which adds considerably to the cost. Significant savings can be achieved by creating a manual ROADM for locations that do not require frequent configuration changes. This is achieved using a unique front panel configuration of a simple Optical Add Drop Module (OADM) system.

Abstract: A platform is connected over a synchronous network using a GFP encapsulation scheme to a provider device having a first Ethernet interface with a customer device, said platform being arranged for exchanging tagged frames including a virtual LAN identifier (VID) with a service unit over a second Ethernet interface. If an error condition is detected at a GFP port of the platform, a correspondence is retrieved between said GFP port and a VID and a deregistration message including said VID is forwarded to the service unit. If an error condition is detected at the second Ethernet interface responsive to reception of a deregistration message including a VID from the service unit, a correspondence is retrieved between said VID and a GFP port and said deregistration message is forwarded through said GFP port to the provider device in a GFP error message. When several Ethernet interfaces concentrated by a bridge face the provider device, another VID is taken into account in the correspondence retrieving.

Abstract: Engines and methods for operating the engines are provided. The engine includes a means for limiting overspeed in flow communication with a turbine section flowpath, wherein the means for limiting overspeed is adapted to block a first portion of an airflow received along a first direction vector from flowing into an exhaust section flowpath and to redirect a second portion of the airflow received along the first direction vector or a portion of the blocked first portion of the airflow to flow along another direction vector that is closer to parallel with a longitudinal axis than the first direction vector.

Abstract: A heat-exchanger (1) consists of a series of closely-spaced, essentially planar, pressure elements (11). Each pressure-element comprises a laminated plate-pair having surfaces formed to provide a plurality of ribbon like cavities between the plates, through which a working fluid can flow. Each plate-pair is joined around the common perimeter to produce a pressure-tight envelope having fluid-inlet and outlet ports at suitable locations. Between adjoining pressure-elements, heat-conductor plates (20) of corrugated profile are located; providing a series of narrow, approximately triangular-sectioned channels, distributed across each pressure-element, through which hot exhaust-gases can form a counter-flow with that of the pressure-element working fluid. The heat-conductor plates are engineered to react pressure-loading from the pressure-elements.

Abstract: A method and apparatus for maintaining data throughput in a data element includes receiving a clock and a first plurality of instances of data having a first width on an input, sampling consecutive ones of instances of the data having the first width at consecutive ones of a first rising edge and a first falling edge of the clock, respectively, to generate two plurality of instances of sampled data having a first width. The plurality of instances of sampled data is then sampled at a second rising edge of the clock and parallelized to generate a second plurality of instances of parallel data having a second width greater than the first width. The parallel data may then be processed to for example generate statistics to monitor link integrity, prior to being transmitted. A 10 Gbps data transmission speed may be maintained using the IEEE 802.3ae-specified media independent interface clock.

Abstract: This invention relates to a method for determining whether a bovine animal possesses a gene for ?-casein A2 or the gene for ?-casein A1 in its milk by testing the DNA of the bovine animal for the presence of at least one DNA marker (excluding those DNA markers present in the sequence of the genes themselves). In particular, the method uses SNPs as DNA markers for the ?-casein A2 and ?-casein A1 genes.

Abstract: A virtual private network (VPN) service is provided through a shared network infrastructure, with customer edge (CE) devices each having a provider edge (PE) interface having a single layer 3 address in the VPN. An address resolution request message is transmitted by a first CE device on plural layer 2 virtual circuits of its PE interface. The address resolution request message including the layer 3 address allocated to a second CE device of the VPN. In response to reception of such request message at the second CE device, an address resolution response message is returned to the first CE device. In response to reception of this response message, the first CE device maps the layer 3 address allocated to the second CE device to a virtual LAN identifier of the layer 2 virtual circuit on which the response message is received.
