  • Patent number: 6881506
    Abstract: The invention is a new heat and fire resistant material and an improved wildland fire shelter and kit. The material is made of a woven silica-based cloth layered in several possible combinations with foil and fiberglass cloth layers. The layers can be arranged in a variety of sequences to minimize the thermal radiation to the inside of the material or shelter. However, a foil layer must always be the outermost layer to provide protection from radiant heat and a layer of foil must be present between the interior of the shelter or material and any layer of adhesive to limit accumulation of gases inside the shelter if the adhesive or other substance should break down when exposed to heat. The silica cloth, aluminum foil, and fiberglass cloth may be laminated or sewn together. The shape of the fire shelter is a half cylinder with ΒΌ sphere at each end. The shelter is contained in an easy-open polyvinyl bag which provides for quick removal and deployment of the fire shelter.

  • Patent number: 6767465
    Abstract: A process for recovering fine coals and clarifying water for recycling features with three distinct mechanisms: hydrophobic extraction, electrolyte coagulation, and macromolecular flocculation, which if desired may be integrated into a single stage. The hydrophobic extraction is accomplished using oil to form a coal-in-oil mixture. The process water is clarified using a flocculants, more preferably a combination of coagulant and anionic flocculants. With a well defined reagent addition scheme, this process allows a combustible recovery greater than 88% at an ash content less than 11%, while producing a clean water containing less than 20 ppm suspended solids from a tailing's stream. The coal-in-oil mixture may be used as a fuel for example in coal-firing boilers and power generators.

  • Publication number: 20040107963
    Abstract: A device and method for deagglomerating powder agglomerates for inhalation. The device includes an inlet connected to a chamber and to a powder source for supplying the chamber with powder agglomerates and a flow of gas that define a swirling fluid flow inside the chamber. The device also includes an outlet connected to the chamber for inhalation such that the swirling fluid flow in the chamber can exit from the chamber as a longitudinal fluid flow that is directed along a longitudinal axis of the outlet, and a secondary fluid flow that is directed away from the longitudinal axis of the outlet. A mesh in the outlet prevents powder agglomerates above a predetermined size from traversing the mesh, and reduces the secondary fluid flow relative to the longitudinal fluid flow exiting from the chamber to thereby reduce powder deposition in a mouth and throat of a user.
