Abstract: A drive link assembly includes a case having a spherically formed inner ring. A clevis is affixed to a surface of the case such that is disposed horizontally between a first end and a second end of the clevis. A spacer having a spherical inset portion is positioned on the surface horizontally between the clevis and the spherically formed inner ring, such that the spherical inset portion is aligned with the spherically formed inner ring. A spherical bearing is seated within the spherically formed inner ring. A rod is affixed to an outer surface of the spherical bearing.

Abstract: A turbine engine fuel delivery system includes a mounting platform, a spray bar assembly and a leaf spring damper with a stack of a plurality of leaf springs. The stack includes a base segment connected longitudinally between a first spray bar contact segment and a second spray bar contact segment. The base segment is connected to the mounting platform and is located a first distance from the spray bar assembly. The first spray bar contact segment engages the spray bar assembly and is located a second distance from the mounting platform. The second spray bar contact segment engages the spray bar assembly and is located a third distance from the mounting platform.

Abstract: An augmentor for a gas turbine engine includes an augmentor spray bar with a spray bar outlet, and an augmentor spray bar tip. The spray bar tip includes a tip body, a tip bushing and a tip support strut. The tip body includes a first flow passage extending therethrough between a tip inlet and a tip outlet, wherein the tip inlet is connected to the spray bar outlet. The tip bushing includes a bushing bore. The tip body extends through the bushing bore defining a second flow passage between the tip body and the tip bushing. The tip support strut connects the tip body to the tip bushing across the second flow passage.

Abstract: A piano key cover having a body of synthetic material pigmented to resemble natural ivory defines a top playing surface having a random orientation of peak-to-valley texture and a multiplicity of fine pores to replicate a surface of natural ivory. A multiplicity of the pores have diameters generally in the range of 0.0002 to 0.0012 inch (0.005 to 0.030 mm). The synthetic material is selected from the group consisting of acrylic polymer, polyurethane, epoxy and the like. A method for forming such a piano key cover and a piano having key covers of the invention are also described.

Abstract: A piano key cover is formed of synthetic material pigmented to resemble natural ivory and having a top playing surface with a random orientation of peak-to-valley texture and a multiplicity of fine pores replicating natural ivory. The key cover is formed by providing a mold, engraving a surface of the mold with a randomly-oriented pattern of peak-to-valley texture replicating natural ivory, placing in the mold a composition of suitable synthetic material pigmented to resemble natural ivory and filler, the filler having the characteristic of being removable from a molded article by further treatment, forming the piano key cover within the mold, and treating the piano key cover to remove the filler thereby causing the surface of the paino key cover to define a plurality of fine pores replicating the surface of natural ivory. A piano including the key cover of the invention, and formed by the above method, is also described.
