20090050537 | Methods for Reduction of Pollutants From Carbonaceous Materials Prior to Combustion - Methods for reducing potential pollutants in carbonaceous materials such as coal, lignites and the like prior to utilization such as by combustion, the invention in preferred embodiments processes such materials by resonance disintegration including inter alia subjection to rapid pressure increases and decreases to reduce the materials to particle sizes of a preferable mean value of approximately fifty microns or less. Pollutants such as sulfur, mercury and other heavy metals bound in a mineral fraction and micronized by such processing can then removed by classification techniques based on physical differences between a micronized carbonaceous fraction and the mineral fraction. Combustion of the micronized carbonaceous fraction substantially free of the mineral fraction results in emissions having reduced levels of sulfur, mercury and other toxic substances. The methods of the invention further include removal of water from carbonaceous materials such as coal, lignites and the like by subjection of such materials to resonance disintegration. | 02-26-2009 |
20090120845 | Beneficiation of Hydrocarbons From Mineral Matrices - Methods for liberating organic carbonaceous products from mineral matrices such as oil shale and the products liberated by the present methods inter alia, the invention in a preferred embodiment subjects oil shale to resonance disintegration including inter alia rapid pressure and directional changes to essentially instantaneously vary forces acting thereon. Oil shale processed by non-impact processing according to the invention liberates kerogen from the mineral matrix to permit subsequent conversion to shale oil or other utilization. | 05-14-2009 |
20100021611 | Processing of grains and the like - Methods for processing of grains and the like and products produced by such processing, the invention in preferred embodiments subjects whole grains or portions of grains to rapid pressure and directional changes in a high velocity fluid stream to instantaneously vary forces acting thereon. Flours of reduced particle sizes having low starch value damage result, the present processing also permitting uniform blending of additives such as during comminution of the grains. Processed grains according to the invention are resistant to spoilage and clumping. Whole grain flours and white flours can be produced according to the invention. Bran, germ and endosperm of grains can also be separated. | 01-28-2010 |

20080204758 | APPARATUS AND METHOD FOR CHEMICAL SENSING - A chemical detector for detecting predetermined chemicals. The chemical detector includes an optical fiber and a polymer having a high fractional free volume higher than about 0.1 that clads a length of the optical fiber. The optical fiber is arranged within an optical resonator. The chemical detector further includes a coherent light source that excites the optical resonator and a chemical signature detector that detects a predetermined chemical based upon a change in a resonance attenuation or refractive index of the optical fiber caused by absorption of the predetermined chemical into the high intrinsic microporosity polymer cladding of the fiber. | 08-28-2008 |
20090246429 | FILLED EPOXY TUBESHEET - A filled epoxy tubesheet comprises an epoxy filled with a metal, such as aluminum flakes. Embodiments of the filled epoxy tubesheets can bend due to stress on the surface rather than crack. Embodiments of the filled epoxy tubesheet can be used to improve Air Separation Module performance by reducing or eliminating leakage through crack in the tubesheet. | 10-01-2009 |
20100269698 | THIN FILM GAS SEPARATION MEMBRANES - A gas separation membrane comprises a blend of polyethersulfone (PES) and aromatic polyimide polymers that may comprise a plurality of first repeating units of formula (I), | 10-28-2010 |
20110026870 | PHOTONIC CRYSTAL FIBER SENSOR - Systems and methods for sensing a target analyte. An example sensor includes a tunable light source that provides a substantially single optical mode of light, a detector, a processor, and a resonator. The resonator resonates light provided by the light source at a predefined frequency. The resonator includes a photonic crystal fiber having a solid region that guides a substantially single optical mode of light and at least one hollow channel adjacent to the solid region. The hollow channel receives a fluid from an external source. The hollow channel is coated with a film having a material that is reactive with the target analyte in a manner that changes the optical properties of the film. The detector detects light from the resonator. A predetermined change in the detected signal as determined by the processor indicates presence of the target analyte. The material in the film is reversible. | 02-03-2011 |
