  • Patent number: 8636869
    Abstract: A liner for repairing damaged pipes, such as underground sewer or gas pipes is disclosed. The liner comprises a TPU coating on a fibrous mat of non-woven fabric. The TPU coating is a high heat resistance polyester TPU which allows an epoxy resin/amine to be saturated in the non-woven fabric and the cure initiated by the use of steam or hot water. The cured epoxy resin converts the liner from a flexible state to a rigid state as the liner is cured in place inside the pipe. The TPU containing liner may also be used with thermoset resins other than epoxy resins, such as polyester resins and vinyl ester resins.

  • Patent number: 8117774
    Abstract: A hanging file folder having fold-up label features can be comprised of a sheet of flat, foldable material having two doubled over ends. A first hanger member can be disposed within one of the doubled over ends and configured to couple to a hanging file drawer rail. A second hanger member can be disposed within the other of the doubled over ends and configured to couple to the hanging file drawer rail. A plurality of tab members formed of the flat, foldable material can be attached to at least one of the doubled-over ends and have pairs of ears extending to the sides of the tab members. The tab members can be positioned to be extended beyond an edge of the doubled over end to which they are attached by folding the tab members and inserting the ears into pairs of slots formed in the doubled over ends.
