  • Patent number: 10016954
    Abstract: Geocomposite articles that can provide a barrier against high conductivity water e.g., ocean water, are described and their method of manufacture, for waterproofing surfaces that contact high conductivity water. The geocomposite article mat includes a woven or non-woven geotextile sheet or mat containing a powdered or granular partially cross-linked acrylamide/acrylate/acrylic acid copolymer across its entire major surface(s). The powdered or granular copolymer has an unexpectedly high free-swell when hydrated with High Conductivity water, such as ocean water. A liquid-impermeable cover sheet is adhered to the upper major surfaces of the filled copolymer-carrying geotextile to provide a primary high conductivity water barrier layer that, if ruptured, is sealed by the swell of an underlying layer of water-insoluble, partially cross-linked acrylamide/acrylic acid copolymer.

  • Patent number: 9248478
    Abstract: A carrier assembly having at least one sealing cup, a fluid bypass and adjustable wash nozzles, as well as a spear assembly having a central through bore, are attached to the distal end of a length of continuous tubing and inserted in to the flow bore of a pipeline. Fluid is pumped through the annular space between the carrier assembly and the pipeline, providing motive force for advancing the carrier assembly within the pipeline. Fluid can bypass the carrier assembly, enter the central bore of the spear assembly, and return to the surface through the central bore of the continuous tubing. A stuck pig or other obstruction is speared, and thereafter retrieved from the pipeline on the continuous tubing.

  • Patent number: 8853299
    Abstract: Described herein, in the preferred embodiment, is a leonardite-based polyurethane resin binder that may be used, among other applications, as a binder in combination with foundry aggregate, e.g., sand, for molding or casting metal parts. The binders described herein comprise a humic substance, preferably leonardite, combined with a polymerizable polyol, an isocyanate, and a polymerization catalyst to make a polyurethane resin binder in situ in a foundry aggregate, such as sand. The lignite is mixed with the polymerizable polyol, thickening and dispersing agents as additives to improve the suspension quality and binder performance of the lignite-containing part of the binder components.

  • Publication number: 20140287975
    Abstract: A builder that is a post-manufacture addition to detergent compositions includes a total soluble salt content of about 70 wt. % to about 90 wt. %, wherein about 40 wt. % to about 90 wt. % of the soluble salts are in the form of an alkali carbonate; about 2 wt. % to about 12 wt. % polycarboxylate co-builder; and about 2 wt. % to about 12 wt. % water for solubility and bulk density control. The builder will be added to a detergent (active surfactant) composition in an amount of about 5 wt. % to about 40 wt. %, preferably about 10 wt. % to about 30 wt. %, more preferably about 15 wt. % to about 25 wt. %, and most preferably about 20 wt. % of the detergent composition based on the total weight of detergent and builder. Generally, a higher percentage of builder composition achieves better results when the wash water is harder (contains higher levels of calcium and/or magnesium, e.g. 400 ppm calcium carbonate).
