  • Patent number: 10049767
    Abstract: A prescribed diagnostic blood test panel is directed to countering autistic and mentally affected births and assessing the continued healthy mental state of the elderly. Six neurotoxins in the blood are analyzed, five of which can produce damage to the brain, namely aluminum, arsenic, lead, mercury and manganese. The sixth, selenium, although a toxin at high levels is in fact a protective element for the brain within a certain concentration range providing important cleansing mechanisms for the alien neurotoxins. This test establishes a baseline set of values for these six neurotoxins and provides guidance for preventive measures to minimize potential risk of neurological consequences. This reduces the risk of autism in new births and is especially valuable to the general public in providing a tool to possibly avoid the consequences of diseases in old age such as dementia, Parkinson's or Alzheimer's.

    Abstract: A prescribed new diagnostic blood test panel is directed for countering autistic and mentally affected births and assessing the continued healthy mental state of the elderly. Six neurotoxins in the blood are analyzed, five of which can produce damage to the brain, namely aluminum, arsenic, lead, mercury and manganese. The sixth, selenium, although a toxin at high levels is in fact a protective element for the brain within a certain concentration range providing important cleansing mechanisms for the alien neurotoxins. This test establishes a baseline set of values for these six neurotoxins and provides needed guidance for preventive measures to minimize potential risk of neurological consequences. This will reduces the risk of autism in new births and is especially valuable to the general public in providing a tool to possibly avoid the consequences of diseases in old age such as dementia, Parkinson's or Alzheimer's.

  • Patent number: 7854910
    Abstract: A conventional air preheater or the conventional design of a preheater is split into two separate sections which are then communicated or connected by a thermally insulated reaction section that is maintained within a predetermined temperature range selected for optimization of heterogeneous chemi-deposition of mercury. The reaction section contains thin stainless steel sheeting which provide an enhanced area of collisional surfaces. Testing has confirmed that this design modification alters the energy heat exchanger to also enhance the oxidation of gaseous elemental mercury in combustion or high temperature source flue gases by providing the surfaces and time for the heterogeneous mechanisms to occur and so control mercury emissions in exhaust gases from coal combustion or other high temperature systems that contain traces of mercury.

  • Patent number: 7517511
    Abstract: Mercury emissions in an exhaust gas are mitigated. Mercury dichloride is formed upon a surface from a substantial portion of the mercury in the exhaust gas. The mercury dichloride sublimes from the surface, and the sublimed mercury dichloride is subsequently removed from the exhaust stream.

  • Publication number: 20080056973
    Abstract: The illustrated embodiment of the invention is a method for mitigating mercury emissions in an exhaust gas. The method includes the steps of noncatalytically forming a chemically deposited compound of mercury on a surface from a substantial portion of the total amount of mercury in the exhaust gas. The deposited compound of mercury is sublimed back into the exhaust gas as volatile mercury dichloride from the surface without any substantial production of elemental mercury. The sublimed mercury dichloride is removed from the exhaust gas by scrubbing.

  • Patent number: 6602445
    Abstract: An additive to a flame reaction forms noncorrosive deposits on cooler metal surfaces, which deposits are more stable than Na2SO4 or K2SO4. By adding molybdenum salts to the flame, an alkali polymolybdate is produced on the cooler metal surface and corrosion is inhibited. Deposition appears to closely reflect the relative thermodynamic stabilities of these salts. The flame processes all chemical molybdenum salt precursors as equivalent sources of molybdenum. The level of molybdenum required is equal to 2 times or more that of the alkali on an atomic basis in the flame environment. The nature of the fuel purity and possible alkali reduction schemes invoked will control the actual quantity and mixing method of the additive. The additive may be directly mixed into the fuel or injected into the burned gas regions of the combustor.

  • Patent number: 6328911
    Abstract: An additive to a flame reaction is provided which forms noncorrosive deposits on cooler metal surfaces which are more stable than Na2SO4 or K2SO4. The additive preferentially combines with the sodium or potassium, and sulfates of these will not be formed. By adding tungsten, tungsten salts or tungsten percursors to the flame, a complex sodium tungstate is produced on the surface of the cooler metal object in a dense form and corrosion is inhibited. The level of tungsten preferably present at an atomic concentration is equal to 1.5 to 2 times that of the sodium in the specific flame environment and possibly a little higher for potassium. The nature of the fuel and possible alkali reduction schemes will control the quantity and mixing method of the additive. The additive may be directly mixed into the fuel or injected into the burned gas regions of the combustion, Ta and Nb also appear as possible substitutes for W in the invention.
