Patent number: 11980939Abstract: An electromagnet alignment system for in-situ alignment of a magnetic particulate material is provided. The magnetic particulate material is dispensed through an orifice of a dispensing nozzle used for 3D printing. The system has an electromagnet assembly having a coil. The coil is configured to generate a pulsed magnetic field having a target magnetic flux intensity upon energization of the coil when the magnetic particulate material is being heated and moved through the dispensing nozzle. As a result, the magnetic particulate material is at least partially aligned with respect to a direction by the pulsed magnetic field. The system further includes a power source for implementing the energization of the coil.Type: GrantFiled: April 15, 2021Date of Patent: May 14, 2024Assignee: UT-BATTELLE, LLCInventors: Mariappan Parans Paranthaman, Brian K.

Patent number: 10586640Abstract: A bulk high performance permanent magnet comprising a neodymium-iron-boron core having an outer surface, and a coercivity-enhancing element residing on at least a portion of said outer surface, with an interior portion of said neodymium-iron-boron core not having said coercivity-enhancing element therein. Also described herein is a method for producing the high-coercivity bulk permanent magnet, the method comprising: (i) depositing a coercivity-enhancing element on at least a portion of an outer surface of a neodymium-iron-boron core substrate to form a coated permanent magnet; and (ii) subjecting the coated permanent magnet to a pulse thermal process that heats said outer surface to a substantially higher temperature than an interior portion of said neodymium-iron-boron core substrate, wherein said substantially higher temperature is at least 200° C.Type: GrantFiled: January 25, 2017Date of Patent: March 10, 2020Assignees: UT-BATTELLE, LLC, IOWA STATE UNIVERSITY RESEARCH FOUNDATION, INC., LAWRENCE LIVERMORE NATIONAL SECURITY, LLCInventors: Mariappan Parans Paranthaman, Michael A.

Patent number: 5812729Abstract: A new light-transmitting device using a SCIN glass core and a novel calcium sodium cladding has been developed. The very high index of refraction, radiation hardness, similar solubility for rare earths and similar melt and viscosity characteristics of core and cladding materials makes them attractive for several applications such as high-numerical-aperture optical fibers and specialty lenses. Optical fibers up to 60 m in length have been drawn, and several simple lenses have been designed, ground, and polished. Preliminary results on the ability to directly cast optical components of lead-indium phosphate glass are also discussed as well as the suitability of these glasses as a host medium for rare-earth ion lasers and amplifiers.Type: GrantFiled: July 21, 1995Date of Patent: September 22, 1998Assignee: Lockheed Martin Energy Systems, Inc.Inventors: Stephen W. Allison, Lynn A. Boatner, Brian C. Sales

Patent number: 5298329Abstract: A glass composition and method of preparation utilizes a mixture consisting of phosphorus oxide within the range of about 40 to 49 molar percent, lead oxide within the range of about 10 to 25 molar percent, iron oxide within the range of about 10 to 17 molar percent and an alkali oxide within the range of about 23 to 30 molar percent. The glass resulting from the melting and subsequent solidifying of the mixture possesses a high degree of durability and a coefficient of thermal expansion as high as that of any of a number of metals. Such features render this glass highly desirable in glass-to-metal seal applications.Type: GrantFiled: April 28, 1992Date of Patent: March 29, 1994Assignee: Martin Marietta Energy Systems, Inc.Inventors: Lynn A.

Patent number: 4847008Abstract: Lead-iron phosphate glasses containing a high level of Fe.sub.2 O.sub.3 for use as a storage medium for high-level radioactive nuclear waste. By combining lead-iron phosphate glass with various types of simulated high-level nuclear waste, a highly corrosion resistant, homogeneous, easily processed glass can be formed. For corroding solutions at 90.degree. C., with solution pH values in the range between 5 and 9, the corrosion rate of the lead-iron phosphate nuclear waste glass is at least 10.sup.2 to 10.sup.3 times lower than the corrosion rate of a comparable borosilicate nuclear waste glass. The presence of Fe.sub.2 O.sub.3 in forming the lead-iron phosphate glass is critical. Lead-iron phosphate nuclear waste glass can be prepared at temperatures as low as 800.degree. C., since they exhibit very low melt viscosities in the 800.degree. to 1050.degree. C. temperature range. These waste-loaded glasses do not readily devitrify at temperatures as high as 550.degree. C.Type: GrantFiled: May 23, 1986Date of Patent: July 11, 1989Assignee: The United States of America as represented by the Department of EnergyInventors: Lynn A. Boatner, Brian C. Sales
