Abstract: A process and apparatus for recovering at least nitrogen, oxygen and/or argon from a feed gas (e.g. air, process gas stream, etc.) can be configured to provide an improvement in operational efficiency with reduced electricity costs. Some embodiments can be adapted so that a substantially liquid feed can be fed for continuous separation processing while liquefaction of the feed may only occur intermittently during low electricity rate time periods. Some embodiments can utilize at least one tank for storage of the liquid feed received from a liquefaction processing unit for storage and use of the liquid feed for the continuous operation of the separation unit(s) utilized for separating desired product outputs from the liquified feed stored in the one or more tanks. The at least one tank can be a single tank or more than one tank (e.g. at least two tanks).

Abstract: An apparatus and process for low temperature regeneration that can be utilized in adsorption systems can include feeding low temperature regeneration gas to at least one off-line adsorber for regeneration of the adsorbent material within the vessel of the off-line adsorber(s). The regeneration time period can be set to facilitate regeneration of the adsorbent material without a need for a high temperature regeneration to occur. Some embodiments can be configured so a post-cooling operation while the regeneration gas is fed to the adsorber(s) can be avoided to permit embodiments to more effectively utilize heating time.

Abstract: An apparatus and process for oxygen production can be configured to utilize flash vapor losses, recovery of regeneration heat and/or utilize a compressor to provide better heat integration and/or less wasteful processing for the recovery of oxygen that can be obtained from electrolysis (e.g., operation of one or more electrolyzers). Some embodiments may utilize all three of these features while other embodiments may use only one of these features or a combination of two of these features.

Abstract: The stream sourcing content delivery system goes to a database and builds a physical stream, based on a schedule. The stream source content delivery system works at a station ID (SID), finds the order of the delivery of content for the station based upon the schedule, and downloads a plurality of music files to its hard drive to enable play back. The stream source content delivery system then concatenates the files, to create stream, and awaits the request of one or more stream recipients. Some preferred system embodiments further comprise a fail-safe mode, whereby a loop of music is generated from the downloaded stream, and is delivered to one or more users when further access to content is interrupted, such that recipients experience an uninterrupted delivery of a plurality of files, e.g. songs.

Abstract: Apparatus and methods of mixing and dispensing small samples are described. Samples may be mixed in a small vessel (12) which is provided with an impeller (20) located at or adjacent its base (14) and driven by a shaft (22) extending through the base. Mounted for rotation within the vessel, either with the impeller or independently thereof, is an agitator means such as a helical spring (28) which is compressible towards the impeller under applied load. Samples may be dispensed from the vessel using a piston member (40) having a through passage (44). The piston member is insertable into the vessel to force the sample therefrom through the passage.

Abstract: A method is provided which directs users to the closest mirror site for desired content. For each mirrored instance of a content store, the distance is determined to each of the networks from which users connect, wherein the determined distance is typically based upon the number of hops and or latency. The localization information is stored, such as by populating a localization database or a localization web service. Upon receipt of a user request for a web page that includes a link to localized/mirrored content, the stored localization information is queried, to determine the closest mirror to the user, based upon the IP address of the user terminal or network. A web page is then generated and transmitted to the user, which comprises a localized link to the determined mirror site. When the user selects the localized link, the user is automatically directed to the closest, i.e. local, mirror.
