  • Publication number: 20240093785
    Abstract: A seal for sealing a gap between rotatable shaft and a vessel wall includes an adapter plate fixed to the vessel wall. A stator plate is attached to the adapter plate. An interfacing boot rotates with the rotatable shaft and has a lip in sliding contact with the stator plate. A central boot is sealingly engaged with and rotates with the rotatable shaft. A drive ring rotates with and is axially movable with respect to the rotating shaft. An anchor ring is fixable non-rotatably and axially to the rotatable shaft. A bias member urges the anchor ring and the drive ring apart. A compression member compresses the bias member, and upon release the bias member urges the drive ring forwardly from the anchor ring. A sealing method includes steps for assembling the seal.

  • Publication number: 20170081864
    Abstract: The present invention provides a device for applying a fluid sealant with a light touch, the device comprising a wand with a fluid sealant supply, either as part of the wand or as a separate supply tube, attached to the top of an applicator head via a universal joint, wherein the applicator head has a chamber on its underside which is sufficiently large to enable a constant supply of a fluid sealant to a substrate that is to be sealed, and the applicator head has a chamber edge disposed around its lower periphery adapted to strike the sealant flat. In addition, the present invention provides methods of using the devices to form a seal, e.g. a weather-resistive barrier on a sheathed building structure, by applying a flexible and compressible foam to gaps in the structure. The foam may comprise one or more aqueous polymer having a glass transition temperature of less than 25° C.
