Publication number: 20150034279Abstract: 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.Type: ApplicationFiled: March 18, 2014Publication date: February 5, 2015Inventor: JAMES G.

Publication number: 20120259866Abstract: 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.Type: ApplicationFiled: December 9, 2011Publication date: October 11, 2012Inventors: L. Suzie AUSTIN, Kevin BRIDGES, James G. DAVIDSON, Rebecca DILWORTH, David T. RAGER, James T. RIDGEWAY, II

Patent number: 5199185Abstract: 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.Type: GrantFiled: June 20, 1991Date of Patent: April 6, 1993Assignee: Western Dry, Inc.Inventor: James G.
