    摘要： In order to effect a seal a porous material which comprises one side of two opposing surfaces is used to restrict and evenly distribute externally pressurized gas, liquid, steam, etc. between the two surfaces, exerting a force which is opposite the forces from pressure differences or springs trying to close the two faces together and so may create a non-contact seal that is more stable and reliable than hydrodynamic seals currently in use. A non-contact bearing is also disclosed having opposing surfaces with relative motion and one surface issuing higher than ambient pressure through a porous restriction, wherein the porous restriction is part of a monolithic porous body, or a porous layer, attached to lands containing a labyrinth, the porous restriction and lands configured to not distort more than 10% of a gap created from differential pressure between each side of the porous restriction.

    摘要： In order to provide web handling which mitigates marking of the web, externally-pressurized porous media gas bearings are used for vacuum rollers, which provide differential tension, and also for air turns, which provide non-contact turning of webs. The porous media gas bearings mitigate three of the biggest issues with the current technology, including cost, high flow rates and low pressure, and web marking. By introducing positive pressure or both, various configurations are presented which allow for improved differential tension, or non-contact conveyance. By also employing externally-pressurized radial bearings, more alternatives are provided, including conveyance and lateral motion of webs without the use of motors. Lastly, employing novel lightweight materials allows for yet other configurations which also employ some of the same aforementioned benefits.

    摘要： A long travel aerostatic linear stage includes a plurality of rails, a plurality of planar bearing plates, and a plurality of porous media gas bearing. The plurality of planar bearing plates are aligned with and attached to the rails. Each planar bearing plate includes a plurality of metal plates having machined air bearing surfaces. The plurality of porous media gas bearings float on the bearing plates in a non-contact frictionless manner to support a traversing load and control lateral motion of the rails. The rails may include at least one rail which supports the traversing load and at least one rail which controls the lateral motion. The bearing plates are restrained and attached to the rails in a manner that ensures the planar nature of the bearing plates are maintained and the air gap is effective.

    摘要： A porous media ventless thrust bearing seal is disclosed. The porous media thrust bearing may include a primary porous media thrust bearing also serving as a seal ring including porous media positioned over a plenum and a port connected to the plenum, and conductive passages for communicating pressurized fluid to the plenums through the ports of the primary ring. The porous media ventless thrust bearing may also include a treated process gas supplied to a port which is closest to the untreated process gas, at a pressure which is higher than the untreated process gas. An inert gas (or fluid in a liquid state) may be supplied to the remaining port, at a pressure which is the same as the untreated process gas. A certain amount of treated process gas may flow into the untreated process gas, and may prevent the untreated gas from entering the porous media seal.

    摘要： The use of externally-pressurized porous media in shaft sealing for turbomachinery is provided for single seals, tandem seals, double-opposed seals, and a ventless seal. These arrangements provide for significant benefits, such as the following: (a) external pressurization allows frozen seal faces to lift open before rotation, (b) pressure is distributed uniformly across the seal face, as opposed to allowing leakage to pass over it, (c) low flow rates of injected gas are possible, (d) the seal faces are self-defending due to the uniform pressure in the gap, and (e) complete elimination of venting process gas is possible. By employing externally-pressurized porous media sealing, a drastic simplification of seal design, as well as gas treatment and seal panel design, is possible.
