Thin substrates, such as flat glass panels, are levitated on a porous media air bearing creating a pressurized film of air and preloaded against the air film by negative pressure areas. The pressure can be distributed most uniformly across the pressure areas by defusing the pressure through a porous medium. Such a bearing can be used for glass flattening by holding the glass such that the unevenness is migrated to the side opposite the side to be worked on.

An externally pressurized porous gas bearing for operating within a refrigerant environment is disclosed. The gas bearing utilizes shear heating from rotation of a rotor, thereby increasing the pressure and load capacity of the externally pressurized porous gas bearing. The gas bearing is capable of operating when the refrigerant is in a liquid phase and when the refrigerant is in a gaseous phase.

A non-contact air bearing having electrostatic discharge properties may comprise: a porous media element having a bearing surface; a supply line configured supply an externally pressurize gas or fluid to the porous media; and an electrostatic dissipative porous bearing layer on the bearing surface of the porous media element; wherein the externally pressurized fluid flows through the porous media element and creates a thin film between the electrostatic dissipative layer and a substrate supported by the air bearing.

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.

Air bearing for use as seal

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.
