  • Patent number: 11970313
    Abstract: An insulating container having a base and a lid is provided. The lid may be rotatable about a hinge from a closed configuration to an open configuration and may be secured, via one or more latching devices, in the closed configuration. In some examples, the insulating container further includes a pull handle assembly with a telescopic three-stage arm configuration defined by a stowed configuration, a partially extended configuration, and a fully extended configuration. In other examples, the insulating container further includes a wheel assembly with a pair of wheels mounted with one or two axles, and further including a wheel grommet for absorbing shock and cushioning the axle. In still other examples, the insulating container further includes a drain plug assembly on the rear sidewall adjacent to the bottom portion of the base, the drain plug assembly comprising a main tube that cooperatively engages with an outer tube with a plurality of ratchet teeth that engage one or more ratchet keys on the main tube.

  • Publication number: 20220169506
    Abstract: Methods for producing cyclododecasulfur are disclosed, that include the steps of: oxidizing a bromide in aqueous solution to produce a mixture of molecular bromine, tribromide, and bromide; reducing water to produce hydrogen and a hydroxide; and reacting a metallasulfur derivative with the molecular bromine, to produce cyclododecasulfur and a metallabromide derivative.

  • Publication number: 20220169505
    Abstract: Methods for producing cyclododecasulfur are disclosed that include the steps of: reacting a metallasulfur derivative with a molecular halogen to produce cyclododecasulfur and a metallahalide derivative; and reacting the metallahalide derivative with a sulfide or polysulfide to produce the metallasulfur derivative and a halide.

  • Publication number: 20220162068
    Abstract: Methods for producing cyclododecasulfur are disclosed that include the steps of: reacting a bromide with molecular chlorine to obtain molecular bromine and a chloride; oxidizing the chloride in aqueous solution with removal of electrons to obtain molecular chlorine; reducing water with electrons to obtain hydrogen and a hydroxide; and reacting a metallasulfur derivative with the molecular bromine, to produce cyclododecasulfur and a metallabromide derivative.

  • Publication number: 20220162761
    Abstract: Method for producing molecular halogen are disclosed, that include the steps of: oxidizing a halide to produce a mixture comprising one or more of a molecular halogen, a trihalide, and a halide; reducing a polysulfide comprising a higher rank polysulfide dianion to produce a lower rank polysulfide dianion; and recovering molecular halogen from the mixture comprising one or more of a molecular halogen, a trihalide, and a halide.

  • Publication number: 20170196310
    Abstract: A footwear accessory can include an inner strap having a first attachment mechanism and a second attachment mechanism. The inner strap can be sized and configured to wrap around a perimeter of a person's lower leg. In some embodiments, the inner strap is releasably coupled to the lower leg via the first attachment mechanism. The footwear accessory can include an outer strap configured to couple to the second attachment mechanism. In some embodiments, when the outer strap is coupled to the second attachment mechanism, the outer strap covers a majority of the inner strap.

  • Publication number: 20120071432
    Abstract: The present invention concerns compositions, methods and/or apparatus of central administration of various CNS-ac-Live agents. In particular embodiments, intrathecal administration is advantageous for decreasing the systemic concentrations of CNS agent, thereby decreasing side effect toxicity, while allowing more effective delivery of the agent to the site of action, simultaneously decreasing the dosage delivered to the subject. In particular embodiments, ICV delivery may be of use for patients who have previously proven to be refractory to systemic administration of CNS agents, in some cases due to systemic side effects, or for those patients whose symptoms are of sufficient severity to warrant more aggressive therapeutic intervention. ICV administration allows not only lower systemic concentration but also higher therapeutically effective concentration within the CNS.

  • Publication number: 20080047872
    Abstract: In a process for converting methane to liquid hydrocarbons, a feed containing methane is contacted with 0 de-hydrocyclization catalyst under conditions effective to convert said methane to aromatic hydrocarbons, including benzene and/or naphthalene, and produce a first effluent stream comprising hydrogen and 0t least 5 wt % m>35 aromatic hydrocarbons than said feed. At least part the aromatic hydrocarbons from the first effluent stream is then reacted with hydrogen to produce a second effluent stream having a reduced benzene and/or naphthalene content compared with said first effluent stream.
