  • Patent number: 10035101
    Abstract: The specification and drawings present a new apparatus and method for a partial gas separation technique which can be used, e.g., for continuously providing, using a predefined atmospheric air (normally atmospheric air comprises 78% of nitrogen N2 and 21% of oxygen O2), oxygen-enriched gas/air and/or nitrogen-enriched gas/air in fossil-fueled combustion devices/systems to a combustion area/chamber and the like for improving combustion, exhaust and related properties of the apparatus. The partial gas separation technique can be based on forming a predefined directional pattern of a gas mixture of a plurality of gases, using a direction forming element, subsequently moving an output gas from the direction forming element at least along/against one surface of a gas separation element to spatially separate in part the plurality of gases having different molecular weights.

  • Patent number: 9863633
    Abstract: The specification and drawings present a new apparatus and method for continuously providing oxygen-enriched gas/air produced from a predefined atmospheric air (normally comprising 78% of nitrogen N2 and 21% of oxygen O2) to a combustion area/chamber, using an impeller-based apparatus having a duct system. The impeller system can comprise at least one plurality of gates for capturing the oxygen-enriched gas/air to automatically improve processes of combustion, exhaust and/or related properties of the apparatus. The impeller can comprise a plurality of blades which, when rotating/spinning, may create the desired gas density/mass separation of oxygen and nitrogen. Furthermore, a nitrogen-enriched gas/air can be further provided from a predefined atmospheric air using the impeller-based apparatus with at least one plurality of further gates system/duct, gates rotating in sync with impeller blades, for collecting the nitrogen-enriched gas/air to further improve one or more apparatus parameters.

  • Patent number: 9803859
    Abstract: The specification and drawings present a new apparatus and method for continuously providing an oxygen-enriched gas/air using a relative motion of selected surface(s) of an apparatus (such as fossil-fueled combustion device/vehicle) relative to an atmospheric air with a speed exceeding a threshold value for, e.g., improving combustion, exhaust and related properties of the apparatus. An oxygen-enriched gas/air layer can be formed along/near each aforementioned surface from the atmospheric air due to pushing the atmospheric air along the surface(s) during that relative motion and collected by corresponding collector gate(s) located inside the apparatus near/adjacent to the corresponding surface. The apparatus can be an object (e.g., a vehicle) moving through the atmospheric air with a relative speed exceeding the threshold value. Alternatively, the apparatus can be a stationary object (e.g.

  • Publication number: 20130186240
    Abstract: A adjustable jar opener comprising a pair of handles and a pivot connecting the handles is described herein. The pivot provides movement of the handles to rotate relative to each other and the pivot can be disengaged and re-engaged allowing one handle to slide along a blade increasing or decreasing in size to accommodate a variety of jar and bottle sizes. The pivot generally remains engaged by the action of a spring. Rubber grips used on the handles provide compliance between the jar opener and the jar or bottle lid and to increase the contact friction between the jar or bottle and the jar opener.
