Patent number: 8992638Abstract: Measurements are taken of moisture, BTU/lb (British Thermal Units per pound), ash, forms of sulfur, volatile material, grindability, and absorption properties of any of a wide variety of mine-run solid fuels. Using that information, a dry electromagnetic process technology has been developed that can be controlled and monitored to selectively alter and enhance metallurgical solid fuel properties. Specific changes include altering the mechanical structure and chemical composition of solid fuels such as coal, coal coke or petroleum coke, increasing the BTU/lb to optimum levels, decreasing all forms of sulfur, and decreasing ash, while maintaining the BTU/lb of the fuels. A new family of solid fuel designer coals not found in nature can be produced via these methods and apparatus.Type: GrantFiled: November 12, 2013Date of Patent: March 31, 2015Assignee: JY Capital Investment LLCInventors: Jerry L.

Patent number: 8592213Abstract: A first fuel and a second fuel are marked with a marker that can be detected quantitatively in a predetermined concentration range. The second fuel is marked with a binary marker. Decreased concentration of the quantitative marker, presence of a binary marker, or both may be indicative of a fuel that is altered (e.g., mixed, laundered, diluted, or adulterated). Testing a fuel includes testing the fuel for a presence of a first marker in the fuel in a predetermined concentration range, and testing the fuel for a presence of a second marker. The presence of the first marker in the predetermined concentration range and an absence of the second marker may be indicative that the fuel is unaltered. The presence of the first marker in the fuel in a concentration less than the predetermined concentration range or the presence of the second marker may be indicative that the fuel is altered.Type: GrantFiled: April 1, 2011Date of Patent: November 26, 2013Assignee: Authentix, Inc.Inventors: Timothy G. Wilkinson, Erwin Dorland

Patent number: 5759857Abstract: Leakage in a heat exchanger between two liquids which are in indirect heat exchange relationship is detected by marking one of the two liquids with a colorless chemical marker and detecting it in the second liquid by extraction and conversion to a colored material. The heat exchanger liquids are preferably organic liquids which are immiscible with water. The marker is detected in a heat exchanger liquid by extraction of the marker followed by chemical conversion of the marker to a colored material that can be detected visually. Aminoalkylnaphthalenes are suitable markers which can be extracted by an acidic aqueous solution and converted to a colored material by reaction with a diazotized aromatic amine. Phenylazoalkylphenol derivatives are also suitable markers which can be extracted and simultaneously converted to a colored material with a detection reagent which is comprised of water and a water-soluble amine.Type: GrantFiled: September 26, 1996Date of Patent: June 2, 1998Assignee: Amoco CorporationInventors: Shri K.

Patent number: 5162235Abstract: Reactions leading to insoluble sediments formation in distillate fuel are accelerated by forcing oxygen into solution in the fuel at pressures of between about 90 and 110 psig and then stressing the fuel under conditions of accelerated storage at temperatures of between about 40.degree. C. to 100.degree. C. The method then makes use of gravimetric determination of the total insolubles formed. The stability of the fuel over a period of time as well as its comparative stability to other fuels can then be predicted from the amount of insolubles formed. The method can be carried out by using a specialized pressure vessel.Type: GrantFiled: June 27, 1989Date of Patent: November 10, 1992Assignee: The United States of America as represented by the Secretary of the NavyInventors: Dennis R.
