Abstract: This application describes powdered fuels, methods of producing powdered fuels source, and dispersions of powdered fuels, as well as systems, kits, and methods for producing and adapting combustion devices to burn powdered fuel, either as a sole fuel source or in combination with existing fuel sources. Exemplary embodiments include engines and furnaces adapted to combust powdered fuel.

Abstract: Methods, systems, and devices convert biomass from the field to provide heat, motive working gas, electrical energy, or fuel such that the biomass directly replaces or supplements liquid fossil fuels wherever these fuels may be used. The methods include procedures for harvesting the biomass, reducing it to a transportable form, purifying it and blending additives as necessary, and finally reducing the refined biomass to an explosible particle size distribution generally finer than 80 mesh for heating applications or 200 mesh for application in internal or external combustion engines. The present invention preferably includes transportation of the finished powder to storage units at the end user site, where the fuel is used by continuous delivery, metering, and dispersal in air to produce a continuous supply of an explosible fluid dispersion for direct energy conversion. Systems of automatic production for a variety of applications are also described.

Abstract: A wound dressing comprising, an elastomeric film permeable to water vapor and having adhesive on a front surface thereof. The dressing has a pair of release sheets extending to a central portion of the film to releasably cover the adhesive. The release sheets are treated throughout with a coating to permit release from the adhesive, with end margins only of the release sheets being additionally treated to more aggressively adhere to the adhesive than a central portion of the release sheets.

Abstract: There is disclosed a bandage which permits drying of a wound or the wound exudate and yet which provides a barrier to bacteria, said bandage comprising an absorbent pad, a barrier film positioned over the surface of said pad, said barrier film being gas permeable and yet substantially impermeable to bacteria, an adhesive coated film or fabric positioned over and around the periphery of the pad and barrier film, said adhesive coated film or fabric being bonded to the periphery of the barrier film thus creating an open window in the center portion of the adhesive film, the adhesive coated film or fabric extending beyond the perimeter of the barrier film and said pad such that when the bandage is applied to the skin of a patient, the portion of the adhesive coated film or fabric extending beyond the perimeter of the pad and barrier film will contact the skin of the patient and form a means of attachment to the skin, the adhesive coated film or fabric and barrier film together forming a bacteria impermeable barri
