Abstract:
Relatively high speed methods for increasing the bulk density of coal particles without impacting the coal particles and an apparatus for compacting coal for making metallurgical coke. The method includes depositing coal particles onto a charging plate external to a coking oven. The charging plate has side walls, and at least one movable end wall to provide an elongate bed of dry, uncompacted coal having an upper surface on the charging plate. The uncompacted coal is compacted by passing a vibratory cylindrical compactor along a length of the uncompacted coal for a number of passes sufficient to decrease a thickness of the bed of coal to less than about 80 percent of an original thickness of the uncompacted coal. The vibratory cylindrical compactor has a length to diameter ratio ranging from about 1.4:1 to about 2:1.
Abstract:
An apparatus for providing reaction of fluids and separation of products with increased residence time. The apparatus includes a stationary shell, a rotating hollow cylindrical component disposed in the stationary shell, a residence-time increasing device external to the stationary shell, a standpipe for introducing fluid into an interior cavity of the hollow cylindrical component from the residence-time increasing device, a first outlet in fluid flow communication with the interior cavity of the hollow cylindrical component for a less dense phase fluid, and a second outlet in fluid flow communication with the interior cavity of the hollow cylindrical component for a more dense phase fluid.
Abstract:
A system and method for documentation, analysis, and/or diagnosing of dermatological aspects of a human body. The system has a predetermined arrangement of at least two image sensors selected from visible light sensors, ultraviolet (UV) light sensors, infrared (IR) sensors and other spectral sensors. Each of the image sensors has an effective normalized focal length of from about 8 to about 80 millimeters, an aperture stepped-down to at least f/4 or higher F-stop, and a shutter exposure length of no longer than about 125 milliseconds. Output from the image sensors provide a single relatively high resolution image of a skin surface of the human body obtained from a distance of at least about 0.1 meters. A data collection and processing system is integrated with the image sensors to provide storage, analysis, and output of in-situ dermatological information to a system operator.
Abstract:
A method for improving air filtration efficiency of a fibrous non-woven media and a fibrous non-woven air filtration media having improved filtration efficiency. The method includes applying to fibrous material at least about 0.05 wt. % based on a total weight of the fibrous material of chemical treatment comprising an alkoxylated silicone copolymer. The chemical treatment is effective to provide an improvement in an E3 filtration efficiency value of the filtration media as tested according to ASHRAE 52.2 of about 20 % or more compared to an E3 filtration efficiency value of fibrous material devoid of any chemical treatment.
Abstract:
A fuel composition for a direct fuel injected gasoline engine comprising, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for an internal combustion gasoline engine. The fuel composition includes a major amount of fuel and a minor, effective amount of a quaternary ammonium salt having a thermogravimetric analysis (TGA) weight loss of greater than 50 wt.% at 350° C. The amount of quaternary ammonium salt present in the fuel is sufficient to improve performance of the direct fuel injected engine having combusted the composition compared to the performance of such engine having combusted a fuel composition that does not contain the quaternary ammonium salt.
Abstract:
A system for reducing the occurrence of fires in a fabric filter dust collection system. The system includes an elongated housing having a first end and a second end distal from the first end. A gas flow inlet is provided in flow communication with an interior portion of the housing for flow of gas and particulates from a source into the housing. A gas flow outlet is provided in flow communication with the housing for flow of gas and particulates out of the housing and into the dust collection system. An elongated spark arrestor is disposed in the housing between the first end and the second end. The spark arrestor has a plurality of spaced-apart, wedge-shaped members having a gap between adjacent members sufficient to interrupt the flow of combustible particles from the source to the dust collection system.
Abstract:
A separator for an energy storage cell having a microporous matrix including a reversible porosity-controlling agent. The porosity-controlling agent is selected from the group consisting of agents that change size as a function of temperature, agents that change size as a function of electrolyte concentration, and agents that change size as a function of temperature and electrolyte concentration to provide a change in an overall porosity of the separator.
Abstract:
The invention provide a method and apparatus for decreasing gas flow rates in a sole flue gas system for a coke oven during at least an initial coking operation after charging a coking oven with coal (43). The method includes providing a duct system (96, 98) between a first coke oven having a first coking chamber (18) and a second coke oven having a second coking chamber (18) to direct at least a portion of gas from a gas space (41) in first coking chamber (18) to the second coke oven thereby reducing a gas flow rate in the first sole flue gas system of the first coke oven. Reduction in sole flue gas flow rates has a beneficial effect on product throughput, the life of the coke oven and environmental control of volatile emissions from coke ovens.
Abstract:
A process for stabilizing lignin fibers, stabilized lignin fibers made by the process and carbonized fibers made from stabilized lignin fibers. The process includes heating lignin fibers to a temperature ranging from about 100° to about 220° C while the fibers are in an atmosphere of air and HC1 gas, generated as air is bubbled through concentrated hydrochloric acid for a period of time sufficient to stabilize the lignin fibers.
Abstract:
A method for reducing an iron-containing material to a metalized iron product. The method includes feeding from about 5 to about 25 percent by weight, based on a total weight of iron-containing material having a total iron content of from about 60 to about 85 % by weight and hot coke to a coke dry quenching (CDQ-SP) apparatus. The iron-containing material is reduced in the CDQ-SP apparatus to metalized iron product having a degree of metallization of greater than about 90 % by weight. The metalized iron product is then separated from a quenched coke product.
