A bump foil for a compliant foil gas bearing having parallel rows of corrugations or bumps, a first series of bumps of equal height spaced equidistant from one another and a second series of bumps of a lesser height with each bump of the second series disposed between bumps of said first series. The bump foil can be fabricated from metals having a thickness greater than that of conventional bump foils to increase load capacity of the gas bearing without sacrificing compliance required for Coulomb damping.

Bump foil design for improved damping and load capacity from compliant

A method and apparatus for increasing the load capacity and damping capability of a three pad compliant foil gas bearing by establishing a gas pressure force between each pad and a shaft supported by a sleeve containing the bearings.

A process for the integration of a chemical absorption separation of oxygen and nitrogen from air with a combustion process is set forth wherein excess temperature availability from the combustion process is more effectively utilized to desorb oxygen product from the absorbent and then the sensible heat and absorption reaction heat is further utilized to produce a high temperature process stream. The oxygen may be utilized to enrich the combustion process wherein the high temperature heat for desorption is conducted in a heat exchange preferably performed with a pressure differential of less than 10 atmospheres which provides considerable flexibility in the heat exchange.
