Patent number: 10645945Abstract: A method and apparatus is provided for forming at least a portion of a beverage from a co-milled powdered composition. An amount of a co-milled powdered composition is combined with a fluid to produce at least a portion of a beverage. The co-milled powdered composition is obtained from co-milling together at least one powdered ingredient having a difficult to disperse or dissolve portion with one or more dispersion facilitator components to form a co-milled powder effective to enhance the dispersion or dissolving of the powder when forming a food or beverage.Type: GrantFiled: July 15, 2011Date of Patent: May 12, 2020Assignee: Intercontinental Great Brands LLCInventors: Gerald Olean Fountain, Philip James Oxford, Amy L.

Patent number: 9662733Abstract: Methods for welding a particle-matrix composite body to another body and repairing particle-matrix composite bodies are disclosed. Additionally, earth-boring tools having a joint that includes an overlapping root portion and a weld groove having a face portion with a first bevel portion and a second bevel portion are disclosed. In some embodiments, a particle-matrix bit body of an earth-boring tool may be repaired by removing a damaged portion, heating the particle-matrix composite bit body, and forming a built-up metallic structure thereon. In other embodiments, a particle-matrix composite body may be welded to a metallic body by forming a joint, heating the particle-matrix composite body, melting a metallic filler material forming a weld bead and cooling the welded particle-matrix composite body, metallic filler material and metallic body at a controlled rate.Type: GrantFiled: July 29, 2008Date of Patent: May 30, 2017Assignee: Baker Hughes IncorporatedInventors: John H. Stevens, Redd H. Smith, James A. Oxford, Jose E. Ramirez, Nathan D. Ames, Shuchi P. Khurana

Patent number: 9386784Abstract: Methods and systems for continuously producing foaming compositions from powders, granules, and/or particulate are provided and/or powders, granules, and/or particulates that contains high pressure gas. The methods and systems are configured to reduce energy costs and overall processing time and, thus, provide advantages over the prior batch processes that have lengthy temperature ramp-up and cool-down times due to the shortcomings of using a large pressure vessel.Type: GrantFiled: November 14, 2011Date of Patent: July 12, 2016Assignee: Intercontinental Great Brands LLCInventors: Aaron R. Colmerauer, Vijay K. Arora, Gerald Olean Fountain, Philip James Oxford, Evan J. Turek, Bary Lyn Zeller

Patent number: 8980357Abstract: A foaming composition is provided comprising a particulate ingredient having a plurality of internal voids containing entrapped supercritical fluid having a critical temperature of at least about 10° C. Additionally, a method is provided for preparing such a foaming composition. A supercritical fluid having a critical temperature of at least about 10° C. is contacted with a particulate ingredient having a glass transition temperature above ambient temperature at a temperature above the glass transition temperature of the particulate ingredient, wherein the particulate ingredient comprises a plurality of internal voids. The particulate ingredient is held at the temperature above the glass transition temperature of the particulate ingredient for a period of time effective to allow transfer of the supercritical fluid into the plurality of internal voids of the particulate ingredient.Type: GrantFiled: November 21, 2007Date of Patent: March 17, 2015Assignee: Intercontinental Great Brands LLCInventors: Thomas Philip Imison, Philip James Oxford, Stefano Ceriali, Bary Lyn Zeller
