摘要:
A PSA system that purifies a feed gas, such as a reformate gas in fuel cell system. The PSA system includes a series of vessels housing an adsorbent or combination of adsorbents that adsorb carbon monoxide, carbon dioxide, nitrogen, water and methane in the reformate gas. The adsorbent vessels are connected to each other and a feed manifold, a product manifold and an exhaust manifold through suitable conduits, where the gas flows are controlled by a product rotating valve and feed rotating valve or a series of open/shut valves. A specialized PSA cycle controls the valves so that the vessels cycle through various stages of equalization, blow-down, purge, pressurization and production to purify the feed gas.

A method of supplying hypoxic gas includes supplying a hypoxic gas with a hypoxic gas supply at a continuous flow rate; and delivering the hypoxic gas intermittently with a conserving mechanism so that an effective hypoxic gas flow rate at least twice the flow rate from the hypoxic gas supply is realized.

A basketball system may include a basketball goal and a support structure sized and configured to support the basketball goal at a desired height. The basketball goal may include a rim assembly, which may include a ring, one or more rim braces and one or more reinforcing members connected to the ring and the rim braces. The support structure may include a support pole. The basketball system may include a support member connected to a lower end of the support pole, which may form a generally T-shaped configuration. The support member may have a generally rigid construction and may be connected to a support surface to help secure the support pole in a generally fixed position. The basketball system may also include one or more braces that may have a low profile and that may be connected to the support pole and/or the support member.

A trailer may include an extension that is sized and configured to extend the length of the trailer. Advantageously, the extension may allow the trailer to be shipped in a standard-sized container. In particular, the extension may allow the trailer to be shipped within a 92 inch container. The extension may also extend the length of the trailer to allow, for example, items that are about 96 inches or 8 feet in length to be positioned in the trailer. Thus, the extension may allow the trailer to be shipped in a standard-sized container and allow the trailer to carrying items such as drywall or sheets of plywood that are 8 feet in length.

A table that includes a table top with a first half which is pivotally connected to a second half. The first and second halves of the table top are movable between a first position in which the halves are generally aligned and a second position in which the halves are generally placed adjacent to each other. The first and second halves of the table top are preferably constructed from blow-molded plastic and each of the halves desirably have a generally hollow interior. The first and second halves of the table top may include interlocking portions that are interconnected when the halves are in the aligned position. Desirably, the interlocking portions have generally hollow interiors that are integrally formed with the generally hollow interiors of the halves of the table top during the blow-molding process. The table top may also include one or more overlapping portions that are interconnected when the halves of the table top are in the aligned position. The overlapping portions may also have generally hollow interiors that are integrally formed with the generally hollow interiors of the halves of the table top during the blow-molding process.

A modular enclosure, such as a shed, may include sidewalls and a roof. The roof, for example, may include one or more roof panels. The roof may also include a truss that is sized and configured to support the roof panels. The shed may also include one or more support beams that may be connected to the truss and may be connected to one or more panels. The shed may include one or more brackets used to connect a pair of panels that are positioned at an angle to form a corner of the shed. The shed may also include a cover, which may include one or more receiving portions sized and configured to receive at least a portion of the brackets. A plurality of roof panels may be positioned within a shipping container to form storage areas or cavities sized and configured to receive all or at least a portion of one or more floor panels.

A table may include a table top, a frame and one or more support members such as legs. Advantageously, the table top may include a generally planar upper surface and a generally planar lower surface. In particular, the lower surface of the table top may be substantially free of any downwardly extending projections such as a lip. Desirably, the table includes a frame and at least a portion of the frame is exposed and visible when the table is being used. In addition, the table may include one or more guard members that are sized and configured to protect portions of the table, such as the corners. Significantly, the guard members may be selectively connected to the table top or the frame, which may allow the guard members to be repaired or replaced.

A table and bench system may include a table and one or more benches that may be selectively attached and detached to the table. Advantageously, this may allow the table and benches to be easily moved, transported and stored. In addition, the table and bench system may include a handle that may assist in moving, transporting or storing the table and benches. Preferably, when the benches are attached to the table, the benches top are generally aligned to facilitate stacking of the table and benches. In addition, when the benches are attached to the table, the legs of the table are preferably disposed generally adjacent to the legs of the benches. Further, the upper surfaces of the benches tops preferably face in an opposite direction than the upper surface of the table top because that may create generally aligned surfaces, which may facilitate stacking and shipping of the table and bench system.

The present invention relates to methods and systems for streaming content and in particular, live content. The method includes the steps of: receiving a content stream; periodically encoding the received stream into a sequence of content files to thereby create a plurality of sequential content files; assigning a sequence identifier to each content file; storing the files on a host; delivering a data file to a media player responsive to a request for live content, said data file including information enabling the media player to sequentially and individually request each content file from the host and play the requested content file; and delivering requested content files responsive to each request.
摘要:
A lighting system for a basketball system may be movable between a first position in which the lighting system is disposed behind the backboard and a second position in which the lighting system is disposed in front of the backboard to allow maintenance to be performed on the lighting system. When the lighting system is in the second position, the lights are preferably disposed at least proximate the rim. Advantageously, the lighting system may be pivotally connected to the support pole of the basketball system by at least some of the same structure that connects the basketball goal to the support pole. In addition, if the height of the basketball goal is adjustable, that may allow the height of the lights to be adjusted when the lighting system is in the second position.
