Patent number: 5705132Abstract: The present invention is a reactor for combustion synthesis of inorganic powders. The reactor includes a reaction vessel having a length and a first end and a second end. The reaction vessel further has a solution inlet and a carrier gas inlet. The reactor further has a heater for heating both the solution and the carrier gas. In a preferred embodiment, the reaction vessel is heated and the solution is in contact with the heated reaction vessel. It is further preferred that the reaction vessel be cylindrical and that the carrier gas is introduced tangentially into the reaction vessel so that the solution flows helically along the interior wall of the reaction vessel. As the solution evaporates and combustion produces inorganic material powder, the carrier gas entrains the powder and carries it out of the reactor.Type: GrantFiled: December 30, 1994Date of Patent: January 6, 1998Assignee: Battelle Memorial InstituteInventors: Gary D. Maupin, Lawrence A. Chick, Randal P. Kurosky

Patent number: 5704890Abstract: The invention is a real time sensor for therapeutic radiation. A probe is placed in or near the patient that senses in real time the dose at the location of the probe. The strength of the dose is determined by either an insertion or an exit probe. The location is determined by a series of vertical and horizontal sensing elements that gives the operator a real time read out dose location relative to placement of the patient. The increased accuracy prevents serious tissue damage to the patient by preventing overdose or delivery of a dose to a wrong location within the body.Type: GrantFiled: May 31, 1995Date of Patent: January 6, 1998Assignee: Battelle Memorial InstituteInventors: Mary Bliss, Richard A. Craig, Paul L. Reeder

Patent number: 5697043Abstract: The present invention is a novel method for freeform fabrication. Specifically, the method of solid freeform fabrication has the steps of:(a) preparing a slurry by mixing powder particles with a suspension medium and a gelling polysaccharide;(b) making a layer by depositing an amount of said powder slurry in a confined region;(c) hardening a selected portion of the layer by applying a gelling agent to the selected portion; and(d) repeating steps (b) and (c) to make successive layers and forming a layered object. In many applications, it is desirable to remove unhardened material followed by heating to remove gellable polysaccharide then sintering.Type: GrantFiled: May 23, 1996Date of Patent: December 9, 1997Assignee: Battelle Memorial InstituteInventors: Suresh Baskaran, Gordon L.
