  • Publication number: 20150034279
    Abstract: A cold trap heat exchanger with a horizontal and vertical arrangement of vaporization chambers, with vibration pads for vehicle use. Vaporization pipes each have a series of thermo vanes mounted on horizontal arranged pipes. This fluid controls the vaporization of the liquid fluid and surface area causing a liquid film on surface area varies of both tubes and pipes to occur, and this increases the facilitate refrigeration. The pneumatic chambers are filled with liquid N2. These gases are controlled through regulated orifice for back pressure on gas turbines used to move atmosphere circuits across cold trap tubes and veins and flow through vanes for cooling control of designed areas and chambers in cooling application that may be required for cooling.

  • Publication number: 20120259866
    Abstract: A computer system automatically evaluates the performance of a content generator using content created by the content generator and user and content generator interactions with the content. Specifically, the system analyzes data regarding the content, e.g., a peer-review quality score, and analyzes data regarding user and/or content generator interactions with the content, e.g., website comments regarding the content. In addition, the system considers user and content generator interactions with the content on third-party websites, e.g., the number of Facebook® “likes” or other social media actions. The system applies rules to assign values to various data points (e.g., a value of 0.3 may be assigned for each Facebook® “like” by a user). The rules may also define weighing components to incentivize particular actions. Weighed values are summed to evaluate each content generator. The scores for each content generator may be compared to create a content generator ranking.

  • Patent number: 7377272
    Abstract: A method and apparatus for reducing the emissions and improving the performance of an internal combustion engine (40). An input air stream is separated into an oxygen-enriched air stream and a nitrogen-enriched air stream. The nitrogen-enriched air stream is received by a holding chamber (35). The oxygen-enriched air and a combustible fuel are provided to a combustion chamber (45) of the internal combustion engine (40) and a combustion process is initiated.

  • Patent number: 5238629
    Abstract: A process for the agglomeration of coal fines comprises the steps of mixing the coal fines with an agglomerating liquid which is further comprised of a reagent and a solvent portion. The coal fines are thereafter separated from the agglomerating liquid, dried, and preferentially compressed into pellet form. The process also entails the recovery and return of the agglomerating liquid. The agglomerating liquid of the present invention includes the reagent portion which is a member or a combination of the group consisting of aromatic tertiary amines, nonaromatic cyclic amines or primary organic amines. The solvent is an organic solvent, desirably a member or a combination of the group consisting of toulene, chloroform, carbon disulfide or dimethylacetamide. The pellet formed from the process of the present invention is uniquely water resistant and of controllable hardness.

  • Patent number: 5199185
    Abstract: A process for removing moisture from coal comprises transforming the coal to coal fines, polarizing the coal fines to produce an electrical charge differential between the relatively non-conductive water and the relatively conductive coal particles, and removing the water by admixing the coal fines in a drying chamber with a dry gaseous mixture having a different electrical state from the moisture, such that the moisture is selectively attracted to the gaseous media, and then separating the moisture laden gaseous media from the coal fines and collecting the fines. The admixture is accomplished with a vertically oriented cylindrical drying chamber wherein the fines are introduced at the top of the chamber and settle downwardly and the dry, gaseous media is directed upwardly through the chamber in a swirling helical path.
