Abstract: A method of improving fatigue strength in a fan blade includes fabricating a metal fan blade with an airfoil and a root and deep peening the root.

Abstract: A method for protecting a fan blade with an airfoil, a tip, a root and a sheath, the root to be inserted into a hub includes peening the airfoil of the blade; inserting a scrim cloth between the fan blade and the sheath to galvanically isolate the fan blade from the sheath; bonding the sheath to the blade with an epoxy adhesive; peening the blade root; bonding wear pads to the root with epoxy adhesive to galvanically isolate the root from the hub; applying a protective cover to the tip of the blade; and applying a coating to all exposed areas of the blade to inhibit corrosion.

Abstract: A method of extruding a glassy aluminum-based alloy billet, by soaking the billet for sufficient time to heat the billet to an extrusion starting temperature of from about 300° F. to about 600° F. and extruding the billet in a streamline die having an extrusion ratio to keep the adiabatic temperature below the starting temperature while maintaining the streamline die at a temperature of about 400° F. to about 600° F. at a ram speed less than that which would raise the streamline die temperature within this range.

Abstract: Apparatus is provided for forming aluminum alloy ingots in a sealed chamber having a source of inert gas using a crucible positioned inside the chamber for melting aluminum alloy powder. The crucible has a solid top and a source of inert gas therein. An outlet in the crucible is positioned to draw molten alloy from the crucible at a point proximate the lowest point in the crucible.

Abstract: A forged devitrified aluminum alloy of forging devitrified aluminum alloys having a desired shape. The alloy is forged in a plane strain forging die with the axis of extrusion being parallel to the direction of forging.

Abstract: A system and method for producing atomized powder for glassy aluminum-based alloys in an inert gas atmosphere. A melt chamber melts the alloy and it is atomized to form powder. The powder is deposited in at least one catch tank.

Abstract: Differential dynamic content delivery including providing a session document for a presentation, wherein the session document includes a session grammar and a session structured document; selecting from the session structured document a classified structural element in dependence upon user classifications of a user participant in the presentation; presenting the selected structural element to the user; streaming presentation speech to the user including individual speech from at least one user participating in the presentation; converting the presentation speech to text; detecting whether the presentation speech contains simultaneous individual speech from two or more users; and displaying the text if the presentation speech contains simultaneous individual speech from two or more users.

Abstract: A fan blade comprises an airfoil portion and a sheath portion. The sheath portion has a sheath head section, a first sheath flank, and a second sheath flank, both flanks extending chordwise from the forward sheath section. The sheath portion is bonded to the airfoil portion such that the sheath head section covers the forward airfoil edge, defining a blade leading edge. The first sheath flank covers a portion of the first airfoil surface proximate the airfoil forward edge, jointly defining a blade suction surface. The second sheath flank covers a portion of the second airfoil surface proximate the airfoil forward edge, jointly defining a blade pressure surface. The first metallic material is an aluminum alloy containing between about 0.5 wt % and about 3.0 wt % of lithium.

Abstract: A hollow airfoil and a method for manufacturing a hollow airfoil is provided.

Abstract: Exemplary methods, systems, and products are described for creating a virtual license document for material subject to an end-user license agreement (‘EULA’). Embodiments include identifying a licensing clause for the virtual license document; creating metadata describing the licensing clause; and inserting in a markup document the licensing clause and the metadata describing the clause. Identifying a licensing clause for the virtual license document may be carried out by identifying a known licensing clause in an existing end-user license agreement (‘EULA’) in dependence upon licensing clause identification rules. Identifying a known clause in an existing end-user license agreement (‘EULA’) in dependence upon clause identification rules may be carried out by identifying keywords in the existing end-user license agreement (‘EULA’) predetermined to be associated with a known clause in end-user license agreements; and identifying the known licensing clause in dependence upon the keywords.
