20100166243 | Ear warming article including electronic device and easily interchangeable advertising areas - An ear warming article that can be comprised of a C-shaped resilient band, an outer sleeve and a speaker or other electronic device is described. The outer sleeve is dimensioned to contain the resilient band, and includes two insulating, ear-receiving portions as well as a first opening through which the resilient band can be inserted or removed to yield an assembled or disassembled article, respectively. In a preferred embodiment, the article includes an electronic device having one or more speakers located at the ends of the resilient band; additional openings in the outer sleeve may exist for any control functionality associated with the electronic device(s). The outer sleeve can be comprised of a washable fabric material, particularly suitable as a means for interchangeable advertising (team logo, branding, etc.). In other embodiments, the ear warming article includes additional advertising and/or securing features. | 07-01-2010 |

20080245705 | Upgrading of petroleum resid, bitumen or heavy oils by the separation of asphaltenes and/or resins therefrom using ionic liquids - Petroleum resid, bitumen and/or heavy oil is upgraded by the separation of asphaltenes and/or resins from such resids, bitumen and/or heavy oils by contacting them with an ionic liquid with which the asphaltenes and/or resins interact. | 10-09-2008 |
20080251418 | Upgrading of petroleum resid, bitumen, shale oil, and other heavy oils by the separation of asphaltenes and/or resins therefrom by electrophilic aromatic substitution - Heavy, high molecular weight multi ring aromatics present in petroleum resid, bitumen and heavy oils in the form of asphaltenes, heavy resids and polycyclic hetero (N) aromatic molecules are separated from the petroleum resid, bitumen and/or heavy oils, by the process comprising electrophilic aromatic substitution of polar groups onto the heavy high molecular weight multi-ring aromatics thereby rendering them insoluble in and facilitating their separation and recovery from the petroleum resid, bitumen and/or heavy oil. | 10-16-2008 |
20090057196 | Production of an enhanced resid coker feed using ultrafiltration - This invention relates to a high-pressure ultrafiltration process to produce an improved coker feed for producing a substantially free-flowing coke, preferably free-flowing shot coke from an atmospheric and/or vacuum resid feedstock. The process of this invention utilizes a high-pressure ultrafiltration process to produce an intermediate product stream with improved the Conradson Carbon Residue (CCR) content which is utilized in either an improved delayed coking or a fluid coking process. | 03-05-2009 |
20090184029 | Method to alter coke morphology using metal salts of aromatic sulfonic acids and/or polysulfonic acids - A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of oil dispersible or oil soluble metal salts of aromatic sulfonic acids and/or polysulfonic acids is added or contacted with the resid or heavy oil at a point before or after the step of heating the heavy oil to coking temperatures. The addition of additives facilitates the formation of shot coke and inhibits the formation of sponge coke. | 07-23-2009 |
