A key piece of the testing equipment is an enclosure that surrounds the test specimen. Fabricated from high-strength, porous solid material (e.g., porous stainless steel), the enclosure (i) captures the hydrogen gas that diffuses through the wall(s) of the test specimen, and (ii) channels the flow of that gas toward a volume-calibrated reservoir. | 09-25-2008 |
20100122747 | Composite Structures for Hydrogen Storage and Transfer - Compressed hydrogen gas can be stored and transferred in hollow structures with walls that include at least one layer or interlayer of at least one porous metal, the purpose of the latter being to protect one or more surrounding layers from the damage that can be caused by diffusive flux of hydrogen gas. The masses of hydrogen gas that enter the layer(s)/interlayer(s) of the porous metal(s) are continuously or periodically removed from the interconnected pore space in the layer(s)/interlayer(s) of the porous metal(s) to ensure that the pressure(s) of the hydrogen gas remain(s) low—generally less than or equal to one atmosphere. When the structure that holds compressed hydrogen gas is a cylindrical pressure vessel, pipe or pipeline, a manufacturing technique known as “C-forming” can be used to create a wall that contains at least one layer or interlayer of at least one porous metal. | 05-20-2010 |

The update platform is further configured to recognize dependencies associated with the configuration packages. When dependencies are detected, corresponding configuration packages are marked to reflect the dependencies and activation is suspended until the dependencies are satisfied. Upon satisfaction of the dependencies, the dependencies are cleared and the configuration packages are activated.
