Abstract: A non-contact seal assembly includes a plurality of seal shoes, a seal base and a plurality of spring elements. A first of the spring elements includes a first mount, a second mount and a spring beam. The spring beam extends a length longitudinally along a centerline from the first mount to the second mount. The spring beam includes opposing first and second surfaces. The first surface is disposed a first distance from the centerline, and the second surface is disposed a second distance from the centerline. The first distance and the second distance change as the spring beam extends longitudinally along the centerline to provide at least a portion of the spring beam with a tapered geometry. The portion of the spring beam has a longitudinal length that is at least about five percent of the length of the spring beam.

Abstract: Aspects of the disclosure are directed to a seal comprising: a shoe, and at least two beams coupled to the shoe, where a first width associated with the beams exceeds a second width associated with the shoe in a reference direction. Aspects of the disclosure are directed to an engine comprising: a compressor section, a turbine section, and a floating, non-contact seal that includes: a shoe, and at least two beams coupled to the shoe, where the beams extend past an edge of a flowpath surface associated with the shoe in a reference direction.

Abstract: An assembly is provided for rotational equipment with an axial centerline. This assembly includes a primary seal device, a ring structure and a secondary seal device. The primary seal device is configured as a hydrostatic non-contact seal device. The primary seal device includes a plurality of seal shoes and a seal base. The seal shoes are arranged circumferentially about the axial centerline in an annular array. The seal base circumscribes the annular array of the seal shoes. The ring structure is axially engaged with the seal base. The secondary seal device is mounted with the ring structure. The secondary seal device includes a seal ring body and an alignment tab. The seal ring body is configured to substantially seal an annular gap between the ring structure and the seal base. The alignment tab projects out from the seal ring body and into an aperture in the ring structure. The alignment tab is adapted to substantially rotationally locate and/or fix the secondary seal device to the ring structure.

Abstract: A method of moist creping absorbent paper base sheet includes forming a nascent web including at least a major portion of flattened ribbonlike cellulosic fibers of recycled fiber. A creping adhesive coating including an admixture of polyvinyl alcohol and a polyamide crosslinked with epichlorohydrin is applied to a Yankee dryer. The nascent web is passed through a nip, defined between a suction pressure roll and the Yankee dryer, having a controlled loading. The nascent web is adhered to the Yankee dryer and dried on the Yankee dryer to a moisture content corresponding to a sheet temperature, immediately prior to the creping blade, of from about 110° C. to about 121° C. The nascent web is creped at a sheet temperature of from about 110° C. to about 121° C. from the Yankee dryer with an undulatory creping blade bearing against the Yankee dryer to form a moist biaxially undulatory web, which is dried.
