Publication number: 20180354164Abstract: An apparatus 20 and a method 100 for generating and dispensing a powdered 60 release agent during an additive manufacturing build is disclosed. A solid body 28 of release agent material is ground insitu by a grinder 50 and dispensed on a surface of the part 72 to prevent adhesion of an adjacent layer of a base material 70. With the addition of the powdered 60 release agent, a support structure 76 is easily separated from the base material 70 when the part 72 is complete, saving time and preventing the part 72 from sustaining unintentional damage. Since no powdered 60 release agent is actually loaded or stored in the apparatus 20, the potential for spillage, waste, inconsistent dispensing, inadvertent dispensing, and clumping due to humidity is eliminated.Type: ApplicationFiled: August 21, 2018Publication date: December 13, 2018Applicant: U T-Battelle, LLCInventors: Randall F. Lind, Brian K. Post, Phillip C. Chesser, Andrew P. Reis, Alex C. Roschli

Patent number: 8087340Abstract: An improved ceramic tile armor has a core of boron nitride and a polymer matrix composite (PMC) facing of carbon fibers fused directly to the impact face of the tile. A polyethylene fiber composite backing and spall cover are preferred. The carbon fiber layers are cured directly onto the tile, not adhered using a separate adhesive so that they are integral with the tile, not a separate layer.Type: GrantFiled: November 5, 2010Date of Patent: January 3, 2012Assignee: U.T.

Patent number: 7257945Abstract: A method to use diesel fuel alchohol micro emulsions (E-diesel) to provide a source of reductant to lower NOx emissions using selective catalytic reduction. Ethanol is stripped from the micro emulsion and entered into the exhaust gasses upstream of the reducing catalyst. The method allows diesel (and other lean-burn) engines to meet new, lower emission standards without having to carry separate fuel and reductant tanks.Type: GrantFiled: February 10, 2003Date of Patent: August 21, 2007Assignee: U T Battelle, LLCInventors: Michael Delos Kass, Ronald Lee Graves, John Morse Elliot Storey, Samuel Arthur Lewis, Sr., Charles Scott Sluder, John Foster Thomas

Patent number: 6800203Abstract: A method is described to decompose perchlorate in a FeCl3/HCl aqueous solution such as would be used to regenerate an anion exchange resin used to remove perchlorate. The solution is mixed with a reducing agent, preferably an organic alcohol and/or ferrous chloride, and can be heated to accelerate the decomposition of perchlorate. Lower temperatures may be employed if a catalyst is added.Type: GrantFiled: May 29, 2002Date of Patent: October 5, 2004Assignee: U.T. BattelleInventors: Baohua Gu, David R. Cole, Gilbert M. Brown

Patent number: 6553133Abstract: A method and apparatus are provided by which a sheet-forming web may be characterized in four dimensions. Light images of the web are recorded at a point adjacent the initial stage of the web, for example, near the headbox in a paperforming operation. The images are digitized, and the resulting data is processed by novel algorithms to provide a four-dimensional measurement of the web. The measurements include two-dimensional spatial information, the intensity profile of the web, and the depth profile of the web. These measurements can be used to characterize the web, predict its properties and monitor production events, and to analyze and quantify headbox flow dynamics.Type: GrantFiled: September 22, 1999Date of Patent: April 22, 2003Assignee: U.T.

Patent number: 6448299Abstract: A method for regenerating strong-base anion exchange resins utilizing a sequential chemical displacement technique with new regenerant formulation. The new first regenerant solution is composed of a mixture of ferric chloride, a water-miscible organic solvent, hydrochloric acid, and water in which tetrachloroferrate anion is formed and used to displace the target anions on the resin. The second regenerant is composed of a dilute hydrochloric acid and is used to decompose tetrachloroferrate and elute ferric ions, thereby regenerating the resin. Alternative chemical displacement methods include: (1) displacement of target anions with fluoroborate followed by nitrate or salicylate and (2) displacement of target anions with salicylate followed by dilute hydrochloric acid. The methodology offers an improved regeneration efficiency, recovery, and waste minimization over the conventional displacement technique using sodium chloride (or a brine) or alkali metal hydroxide.Type: GrantFiled: January 25, 2000Date of Patent: September 10, 2002Assignee: U.T.

Patent number: 6436346Abstract: A method and apparatus are provided for detecting and monitoring micro-volumetric enthalpic changes caused by molecular reactions. Micro-machining techniques are used to create very small thermally isolated masses incorporating temperature-sensitive circuitry. The thermally isolated masses are provided with a molecular layer or coating, and the temperature-sensitive circuitry provides an indication when the molecules of the coating are involved in an enthalpic reaction. The thermally isolated masses may be provided singly or in arrays and, in the latter case, the molecular coatings may differ to provide qualitative and/or quantitative assays of a substance.Type: GrantFiled: September 14, 1999Date of Patent: August 20, 2002Assignee: U T Battelle, LLCInventors: Mitchel J.

Patent number: 6385363Abstract: An optical switch is formed by introducing light lengthwise to a microcantilever waveguide directed toward a second waveguide. The microcantilever is caused to bend by light emitted from a laser diode orthogonal to the microcantilever and at an energy above the band gap, which induces stress as a result of the generation of free carriers. The bending of the waveguide directs the carrier frequency light to a second receptor waveguide or to a non-responsive surface. The switch may be combined in an array to perform multiple switching functions rapidly and at low energy losses.Type: GrantFiled: March 26, 1999Date of Patent: May 7, 2002Assignee: U.T. Battelle LLCInventors: Slobodan Rajic, Panagiotis George Datskos, Charles M. Egert

Patent number: 6375705Abstract: Oxide dispersion strengthening of porous metal articles includes the incorporation of dispersoids of metallic oxides in elemental metal powder particles. Porous metal articles, such as filters, are fabricated using conventional techniques (extrusion, casting, isostatic pressing, etc.) of forming followed by sintering and heat treatments that induce recrystallization and grain growth within powder grains and across the sintered grain contact points. The result is so-called “oxide dispersion strengthening” which imparts, especially, large increases in creep (deformation under constant load) strength to the metal articles.Type: GrantFiled: March 26, 1999Date of Patent: April 23, 2002Assignee: U. T. Battelle, LLCInventor: Roddie R. Judkins

Patent number: 6358396Abstract: Anion exchange resins sorbed with perchlorate may be regenerated by a combination of chemical reduction of perchlorate to chloride using a reducing agent and an electrochemical reduction of the oxidized reducing agent. Transitional metals including Ti, Re, and V are preferred chemical reagents for the reduction of perchlorate to chloride. Complexing agents such as oxalate are used to prevent the precipitation of the oxidized Ti(IV) species, and ethyl alcohol may be added to accelerate the reduction kinetics of perchlorate. The regeneration may be performed by continuously recycling the regenerating solution through the resin bed and an electrochemical cell so that the secondary waste generation is minimized.Type: GrantFiled: May 8, 2000Date of Patent: March 19, 2002Assignee: U. T. Battelle, LLCInventors: Baohua Gu, Gilbert M. Brown
