    • Seal devices of this invention are prepared by the process of depositing a polymer material onto a metallic substrate to form a composite construction, and shape forming the composite construction into the shape of a seal device. The so-formed seal device comprises a casing member that is formed from the metallic substrate, and a sealing element disposed along a surface of the casing member that is formed from the polymer material for placement against a sealing surface. Seal devices of this invention can be shaped formed into a variety of different types of seals, e.g., lips seals, L-shaped seals, and U-cup seals, which mayor may not be energized. Seal devices prepared according to this invention using such preformed composite construction enable seal formation by a single step of shape forming, without having to both make and form individual seal members, and subsequently combine or join the separately formed seal members together . 15 MAC PAS439923.1-*-6/6/02 10:34 AM 20 25 30 35 .1 -26-
    • 本发明的密封装置是通过将聚合物材料沉积到金属基底上以形成复合结构的方法制备的,并将形成复合结构的形状制成密封装置的形状。 如此形成的密封装置包括由金属基底形成的壳体构件和沿着壳体构件的由聚合物材料形成的用于放置在密封表面上的密封元件。 本发明的密封装置可以成形为各种不同类型的密封件,例如嘴唇密封件,L形密封件和U形杯密封件,其可能不会通电。 使用这种预制复合结构制备的根据本发明制备的密封装置可以通过形成一个单一步骤形成密封,而不必制造和形成各个密封构件,并且随后将单独形成的密封构件组合或连接在一起。 15 MAC PAS439923.1 - * - 6/6/02 10:34 AM 20 25 30 35 .1 -26-

    • A bypass seal (56) for a rotary regenerative air preheater includes primary and secondary seal leaves (58, 60) that are joined at a single position longitudinally intermediate their first and second sends. The first end portion (90) of the primary seal leaf (58) extends longitudinally beyond the first end (92) of the secondary seal leaf (60) and the second end portion of the secondary seal leaf (60) extends longitudinally beyond the second end of the primary seal leaf (58). When installed in the air preheater, the first end portion of the primary seal leaf (58) of each bypass seal (56) in one of the seal rings overlaps the second end portion of the secondary seal leaf (60) of an adjacent bypass seal in the seal ring.

    • A gasket assembly (11) for securing a pair of surfaces (19) together wherein an electrically conductive gasket base (12) having a central opening is provided with a pair of layers (28) secured to opposite sides of the gasket base, with the layers being a fusible alloy, a brazing alloy or a synthetic, thermoplastic material which will melt, without degrading, when the gasket base is heated. The surfaces may be secured to each other by a plurality of bolts (26) to squeeze the gasket assembly therebetween or by some other clamping means. An electrical current is passed through the gasket base to heat it to a temperature sufficient to melt the layers to seal the surfaces to opposite sides of the gasket base.

    • A radial lip seal (10) having a sealing lip (16) made of first and second materials arranged in alternating regions (20, 22) and forming a continuous contact band. The seal is a rotational seal for contacting a shaft or sleeve in a relatively rotatable relationship. The first and second materials have differing physical characteristics to increase hydrodynamic activity at the sealing lip (16). The first material may be a polytetrafluoroethylene material and the second material disclosed may be silicone, fluoroelastomer, nitrile, ethylene acrylic or polyacrylate elastomers. The boundaries (42) between the first and second materials at the contact band preferably intersect the circumferentially extending contact band at an angle. A method of making a radial lip seal is also disclosed wherein an annular wafer (32) of a first material having an undulating circumferential edge (34) with spaced radially recessed portions (36) is placed in a mold (44). A ring (45) of elastomeric material is placed in the mold (44) with the wafer (32). The radial lip seal (10) is then formed by molding the ring (45) of elastomeric material and wafer (32) into the desired seal configuration. The process is completed by forming the sealing lip (16) by cutting the molded wafer (32) and molded elastomeric material contained in the recesses (36) of the wafer (32).
