Abstract: A nasal dilator capable of introducing separating forces in the nasal outer wall tissue, has a resilient member, and a pair of spaced-apart end surfaces which can be forced toward one another from an initial flat position of the dilator to thereby substantially reduce the direct spacing therebetween by an external spacing reducing force. This results in restoring forces in the dilator tending to return it to the original direct spacing between the end surfaces. The resilient member, which is asymmetrical with respect to a centerline of the dilator that is parallel to the long axis of the dilator, has an extended surface at each end surface of the dilator which increases the adhesive surface area. The extended surface is located at each end surface of the resilient member on the side opposite the nose ala (wings) and above the alar furrow.

Abstract: A nasal dilator capable of introducing separating stresses in nasal outer wall tissues has a resilient member and a pair of spaced-apart end surfaces which can be forced toward one another from an initial flat position of the dilator to thereby substantially reduce the direct spacing therebetween by an external spacing reducing force. This results in restoring forces in the dilator tending to return it to the original direct spacing between the end surfaces. Resilient members, which can be asymmetrical with respect to a centerline of the dilator that is parallel to the long axis of the dilator, have a spring rate which continuously diminishes from the centerline to the end surfaces. The edges of the resilient members are contiguous to the edge of the cushion layer so that adhesive on the cushion layer is at the same level as the bottom surface of the resilient members.

Abstract: A fast-dissolving film to be placed in the oral cavity of a person includes melatonin, or melatonin analog, with or without menthol, or menthol analog, that can be absorbed through the oral mucosa directly into the person's bloodstream. The film is thin and made from a low-moisture, non-tacky material that becomes dissolved when hydrated and that is sized so that the substrate can be placed in oral cavities of persons. From 0.3 mg to 10 mg melatonin, or a melatonin analog, and, optionally, menthol, or a menthol analog, are added to the substrate, which is then packaged in a flat, sealed container that can be unobtrusively placed into a pocket carried by the person, thereby making the container readily accessible to the person. In use, the film is removed from the container and placed into the person's oral cavity so that it contacts a mucosal membrane in the oral cavity of the person to thereby hydrate the substrate.

Abstract: A fast-dissolving film to be placed in the oral cavity of a person includes nicotine, or nicotine analog, with or without menthol, or menthol analog, that can be absorbed through the oral mucosa directly into the person's bloodstream for the purpose of reducing a temporary craving for nicotine during periods when smoking is not possible, or for therapeutic purposes, the film being thin and made from a low-moisture, non-tacky material that becomes dissolved when hydrated and that is sized so that the substrate can be placed in oral cavities of persons. From 0.1 mg to 10 mg nicotine, or a nicotine analog, and, optionally, menthol, or a menthol analog, are added to the substrate, which is then packaged in a flat, sealed container that can be unobtrusively placed into a pocket carried by the smoker, thereby making the container readily accessible to the smoker.

Abstract: A system and method for adding superheat to the hot process gas at the discharge of a compressor drive turbine of a high compression ratio gas turbine or aviation gas turbine. The superheat brings the temperature ratio (T2/T1) of the power output turbine into equality with the pressure ratio (P2/P1)(K?1)/K to effect a highly efficient and adiabatic isentropic expansion across the power output turbine. The added superheat contributes to the output power of the engine less any inefficiency of the output power turbine. All of the variables are brought together to develop the proper superheat levels for obtaining the greatest power output possible at minimum fuel consumption levels.

Abstract: A nasal dilator capable of introducing separating stresses in nasal outer wall tissues has a truss of a single body with a resilient member secured therein and a pair of spaced-apart end surfaces which, when forced toward one another from initial positions to substantially reduce direct spacing therebetween by a spacing reducing force external to said truss, results in restoring forces in the truss tending to return to the original direct spacing between the end surfaces. A resilient member, which is symmetrical with respect to a centerline of the truss that is perpendicular to the long axis of the truss, has a spring rate which continuously diminishes from the centerline to the end surfaces. An adhesive on the end surfaces adhesively engages exposed surfaces of nasal outer wall tissues sufficiently to keep the truss attached to the nasal wall surfaces while subjecting them to the restoring forces.

Abstract: A safety device for preventing accidental injury from hypodermic needles comprises an extension for attachment to a standard medical syringe. A standard hypodermic needle attaches to the opposite end of the extension and the extension has an inner cavity for conveying fluid between the syringe and the needle. An outer cover is disposed about the extension for sliding along the length of the extension to cover the needle. The safety device is easily modified to perform as a system for collecting blood or other fluid from a patient by adding a special needle and a blood collection holder at the back end of the extension. In this configuration, the outer cover guards the standard needle and the blood collection holder covers the special needle to prevent accidental injury or disease transmission.

Abstract: A pulse combustor ignitor comprising a small combustion chamber located external to the pulse combustion chamber. A spark ignition source such as a spark plug is associated with the chamber and separate inlets for fuel and air are provided. The fuel/air mixture is ignited by the spark plug and the ignited mixture is directed into the combustion chamber of the pulse combustor until a steady state operation of the pulse combustor is achieved. An air preheater may be used for the air delivered to the ignitor combustion chamber. The flow pattern of the fuel/air mixture and the flame may be controlled by an adjustable passage element located between the respective ignitor and pulse combustor combustion chambers. A flame scanner positioned external to the pulse combustor may be used to sense the entrance of the ignited mixture from the ignitor into the pulse combustor.

Abstract: A shut-off valve for use with high pressure gas cylinders is disclosed which is adapted to automatically retain a residual pressure in the cylinder. The valve includes a check plug axially moveable within the housing which has a hard sealing surface, for establishing high pressure seals and a soft sealing surface for establishing low pressure seals. The plug is spring-biased into the closed position with force selected so that it automatically closes and seals the interior of the cylinder once the gas pressure in the cylinder drops to or below a predetermined threshold pressure.

The pulse combustor includes a rotary valve, a combustion chamber, an inner tail pipe and an outer tail pipe. The combustion chamber and inner tail pipe are conical and tubular sections mounted in longitudinal compression, and the compressive forces are transmitted externally across the junction of the combustion chamber and tail pipe by a strongback assembly. The rotary valve includes first, second, and third closely adjacent cylinders defining an interior air chamber. The cylinders have radially oriented, substantially aligned apertures which define an air intake.
