Abstract: Described is a valve face seal assembly. The assembly includes a moveable member, such as a poppet, and a seal having a sealing portion carried by the moveable member. A seat opposite the sealing portion of the seal has a transaxial seat face and an axial seat face extending axially toward the moveable member at an obtuse angle from the transaxial seat face. When the seal of the moveable member is brought into contact with the seat, a seal is formed with the transaxial seat face and with the axial seat face.

Abstract: A seal assembly (10) comprising a sealing body (40), a shoe (42), a first collar (44), and a second collar (46). The shoe (42) is positioned within a space defined by radially inner surfaces of the sealing body (40), the first collar (44) is positioned on a first axial side of the sealing body (40), and the second collar (46) is positioned on a second axial side of the sealing body (40). These components (40, 42, 44, 46) collectively form inter-component sealing surfaces, pocket sealing surfaces, gate sealing surfaces and/or part sealing surfaces which prevent the infiltration of outside fluid into, and the escape of operative fluid from, a fluid coupling.

Abstract: In forming a bellows-like seal from a welded metallic band, improved mechanical properties may be obtained by welding the ends of a strip forming the band at an angle off-normal to the band rims (and seal axis). The angle may be a single angle (i.e., with a straight weld) or there may be multiple angles (e.g., with a serpentine or other convoluted weld). The weld may extend through the band normal to surfaces of the band or at an angle off-normal. The metallic band may comprise an oxide dispersion strengthened alloy.

Abstract: A new and distinct Boxwood plant is provided which originated as a limb mutation of the ‘Green Velvet’ cultivar (non-patented in the United States). The new cultivar readily can be distinguished from the ‘Green Velvet’ cultivar in view of its significantly larger leaf size. The growth habit is dense, mounded and compact. Attractive deep olive green foliage is formed which well retains its coloration throughout the year in the absence of any substantial color change during the winter. Excellent winter hardiness to at least U.S.D.A. Hardiness Zone No. 5 is displayed. The plant is well suited for consistently providing attractive ornamentation in the landscape.
