  • Patent number: 12370385
    Abstract: A system for delivering breathing gas to passengers includes: a face mask including a face part having a breathing cavity, a tube configured to be supplied by pressurized breathing gas, and a reservoir bag disposed between the tube and the face part. A passage connects the reservoir bag to the breathing cavity so that the system is configured to supply the breathing cavity through the reservoir bag. The reservoir bag includes a front portion and a back portion. The front portion is connected to the face mask, and the system has a stowed configuration and a deployed configuration. In the stowed configuration, the reservoir bag is maintained folded between a backing and the face part.

  • Patent number: 12344581
    Abstract: Inhibitor compositions for abating undesirable polymerization during processing of hydrocarbon stream laden with reactive vinylic monomers are provided. The polymerization inhibitor compositions include at least a first inhibitor compound having a stable nitroxide radical and a second inhibitor including phenylenediamine. Methods of inhibiting the polymerization of monomers using the compositions of the disclosure are also provided. The methods of inhibiting polymerization of monomers include a step of adding a composition of the disclosure to the monomer. In some instances, the monomer is an ethylenically unsaturated monomer. Such ethylenically unsaturated monomers include, but are not limited to, vinyl acetate, acrylonitrile, acrylates, methacrylates, 1,3-butadiene, styrene, isoprene, (meth)acrylic acid, and combinations thereof. Methods of preparing the polymerization inhibitors and compositions of the disclosure are also provided.

  • Publication number: 20250092487
    Abstract: The present disclosure relates to a method using a reagent having a thiocarbonyl functional group to liberate a precious metal such as gold from a material comprising a sulfide, wherein the sulfide encapsulates the precious metal. Such a method comprises contacting the material under acidic conditions with the reagent comprising the thiocarbonyl functional group and optionally producing a residue comprising the precious metal. The present disclosure also relates to the use of a reagent having a thiocarbonyl functional group in methods for extracting a precious metal from a material comprising a sulfide, wherein the sulfide encapsulates the precious metal, the method comprising leaching the precious metal from a residue comprising the precious metal produced from such a method for liberating a precious metal.

  • Publication number: 20240336991
    Abstract: This application pertains to methods of recovering metals from metal sulfides that involve contacting the metal sulfide with an acidic sulfate solution containing ferric sulfate and a reagent that has a thiocarbonyl functional group, wherein the concentration of reagent in the acidic sulfate solution is sufficient to increase the rate of metal ion extraction relative to an acidic sulfate solution that does not contain the reagent, to produce a pregnant solution containing the metal ions.
