20090194480 | METHODS FOR ANALYZING AND REMOVING CONTAMINANTS IN LIQUID HYDROCARBON MEDIA - A method for identifying contaminants within a liquid hydrocarbon media containing contaminants includes adding an optical tag to a water wash, adding the tagged water wash to the liquid hydrocarbon media, emulsifying the liquid hydrocarbon media and analyzing the contaminants in the hydrocarbon media with a microscope. Methods for removing contaminants and evaluating treatment are also provided. | 08-06-2009 |
20100015720 | Dynamic desalter simulator - A small-scale dynamic simulator for crude oil refinery desalters has a pressurized oil deviblis configured to hold a supply of crude oil and a water deviblis configured to hold a supply of wash water. At least one chemical feed pump selectively adds emulsion breaker chemicals to the desalter simulator and a low shear metering pump is configured to pump crude oil and wash water through the desalter simulator. An emulsion forming device forms a crude oil-wash water emulsion that is then received in a desalter vessel. The desalting vessel is fitted with electric grids which simulate those found in electric desalters. The emulsion is resolved within the desalter vessel with the assistance of the emulsion breaker chemicals so the wash water and crude oil form distinct phases, with substantially desalted crude oil removed from an upper portion of the desalter vessel and substantially oil-free wash water removed from a bottom portion of the desalter vessel. A portion of the desalter vessel is substantially transparent to allow visualization of the demulsification process and at least one light source is positioned adjacent to the desalter vessel to aid in visualization of a rag layer formed in the desalter vessel. A heated jacket surrounds the desalter vessel to maintain the desalter vessel at the desired temperature. | 01-21-2010 |
20110014087 | MATERIAL COMPOSITIONS FOR SENSORS FOR DETERMINATION OF CHEMICAL SPECIES AT TRACE CONCENTRATIONS AND METHOD OF USING SENSORS - A method of quantitatively measuring the concentration of a chemical species in a sample solution with a sensor film. A hydrogel sensor film is prepared having a chemical composition comprising an indicator that changes its optical property in the ultra-violet, visible or near-infrared spectral range upon being exposed to the chemical species in the sample solution. The film is exposed to a fixed amount of the sample solution. The concentration of the chemical species in the sample solution is quantified using the average absorbance measured from the sensor film. | 01-20-2011 |
20110301061 | HIGH THROUGHPUT EXPERIMENTATION METHODS FOR PHASE SEPARATION - A process for testing the effectiveness of demulsifying additives on oil/water emulsions includes adding samples containing differing combinations of oil, water and demulsifier to a plurality of elongate reactor vials, wherein each the elongate reactor vial has a longitudinal axis extending from its bottom to its rim. The plurality of reactor vials are placed into a reaction block mounted on a platform of a shaker, wherein the reactor vials are received in stations of the reaction block in a vertical orientation such that the longitudinal axis of each reactor vial is perpendicular to the platform. The reaction block is pivoted the so that the longitudinal axis of each reactor vial is parallel with the platform in a horizontal orientation. The method further includes agitating the reactor vials with the shaker to simultaneously form an oil/water emulsion in each reactor vial while the reactor vials are in the horizontal orientation and then pivoting the reaction block to return the reactor vials to a vertical orientation. The demulsification of the oil/water emulsion in the plurality of reactor vials is observed with the reactor vials in the vertical orientation. In one embodiment, the method further includes using an imaging device to record the demulsification of the oil/water emulsion. | 12-08-2011 |

20090095187 | High-pressure fixed munition for low-pressure launching system - A high-pressure fixed munition for a low-pressure launching system having a cylindrical body with a centrally located bore is provided. The bore of the munition has a reduced diameter on the charge end in which a primer charge is positioned. The bore is filled above the primer charge with a propellant and above the propellant with a payload. The payload may include multiple buckshot pellets, frangible buckshot pellets, tear gas, multiple slugs, frangible slugs, paint balls, rubber pellets, bean bags, or the like. The munition may also include a pressure disk between the propellant and the payload, and tactile ridges or on the outside surface of the munition body or be of a specific color for purposes of identification of the payload. | 04-16-2009 |
20110290141 | Subsonic small-caliber ammunition and bullet used in same - A bullet for use with a small caliber rifle comprises a jacket and a lead core provided within the jacket. The jacket is drawn from a copper alloy material. A bearing surface portion of the jacket has a nominal thickness less than about .010″ and the copper alloy material of at least the bearing surface portion of the jacket has a nominal hardness that is substantially greater than an as-drawn hardness of the copper alloy material of the bearing surface portion of the jacket. | 12-01-2011 |
20110290142 | Subsonic small-caliber ammunition and bullet used in same - A bullet comprises a casing engaging segment, a rifling leade mating segment, and a tip segment. The rifling leade mating segment has a frusto-conical shape tapering from a first diameter at a first end portion thereof to a second diameter at a second end portion thereof. The rifling leade mating segment extends from a first end portion of the casing engaging segment. The tip segment extends from the second end portion of the rifling leade mating segment. The first diameter is greater than the second diameter. | 12-01-2011 |
20130167747 | BULLET WITH CHAMBER SEALING STRUCTURE AND AMMUNITION COMPRISING SAME - A round of ammunition for use in a 5.56 NATO-specification chamber comprises a cartridge casing and a bullet having a casing engaging segment, a sealing band and a groove. The sealing band encircles the casing engaging segment. The casing engagement segment of the bullet is engaged within a bullet receiving opening of the cartridge casing with a rear surface of the sealing band abutting a front edge of the cartridge casing. The groove encircles the casing engagement segment. A rear portion of the sealing band intersects a front portion of the groove. A front face of the sealing band is substantially flat. An angle of the front face of the sealing band is approximately the same as an angle of a neck-to-throat transition portion of the 5.56 NATO-specification chamber. | 07-04-2013 |
