Publication number: 20220086964Abstract: Conductors for use in heating systems are provided. The conductors are configured to have an extended current path for the current and increased resistance as seen by the current. The heating system may be an induction system. For example, the conductor may comprise a conductive material having a surface which faces an induction coil of an oscillating circuit. This surface may have a predetermined pattern of peaks and valleys. The peaks and valleys form a non-linear current path for the induced current when exposed to an electromagnetic field generated by the oscillating circuit. Other conductors such as a heat pipe may be used. The pipe may have walls with varying thicknesses over its length. The varying thicknesses may include a first thickness and a second thickness which alternate. The heat pipe may be used in an induction or direct contact heating system where AC is directly applied to the pipe.Type: ApplicationFiled: November 22, 2021Publication date: March 17, 2022Applicant: UT-Battelle, LLCInventor: Roger A.

Patent number: 11131502Abstract: A system for heating a fluid and an electromagnetic acoustic transducer EMAT system is provided. Both systems have a drive circuit. The amount of heat and the amplitude (and acceleration) of the vibrations is respectively controllable by controlling an input to a terminal of a switch. The heating system comprises a porous graphite foam conductor which is exposed to an electromagnetic field generated by an oscillating circuit. When exposed, the foam conductor conducts induced electric current which heats the same and a fluid in contact with the conductor. The EMAT system comprises at least one magnet configured to generate a static magnetic field, an oscillating circuit and a working element. The working element, when exposed to the static magnetic field and the electromagnetic field produced by the oscillating circuit, vibrates against a load. The vibrations dry the load.Type: GrantFiled: August 14, 2018Date of Patent: September 28, 2021Assignee: UT-BATTELLE, LLCInventors: Roger A. Kisner, Christi R. Johnson, Frederick K. Reed

Patent number: 10284021Abstract: A system for producing light is provided. The system comprises a sealed enclosure surrounding a porous graphite foam conductor which is exposed to an electromagnetic field generated by an oscillating circuit. When exposed, the foam conductor conducts induced electric current which heats the same to product light. The amount of light is controllable by changing the output of a drive circuit. The oscillating circuit comprises a first inductor and a first capacitor. The first inductor has a first terminal and a second terminal. The output of the drive circuit is controlled by turning a MOSFET OFF and ON. The MOSFET is turned ON when an integrated signal representative of a difference between a voltage proportional to the first terminal and a voltage proportional to the second terminal is between a first voltage threshold and a second voltage threshold and based on a timing signal.Type: GrantFiled: August 14, 2018Date of Patent: May 7, 2019Assignee: UT-BATTELLE, LLCInventors: Roger A.

Patent number: 10009526Abstract: An exemplary device includes, on a longitudinal axis, an illumination-light source, an axicon (conic) mirror, an image sensor, and a tilted optical element. The light source provides illumination light propagating forwardly on the axis. The axicon mirror reflects the illumination light radially outward, relative to the axis, to the interior surface of a tube to produce reflected light propagating, from the illuminated interior surface, as imaging light back to the axicon, which reflects the imaging light rearwardly. The image sensor receives at least a portion of the imaging light rearwardly reflected by the axicon mirror. The tilted optical element, situated between the axicon mirror and the interior surface, moves a selected first portion of the imaging light away from being incident on the image sensor, while allowing a second portion of the imaging light to be incident on the image sensor.Type: GrantFiled: February 13, 2014Date of Patent: June 26, 2018Assignee: UT-Battelle, LLCInventors: Roger A.

Patent number: 9612160Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems for determining the temperature of an object using an optical pyrometer. Certain embodiments of the disclosed technology allow for making optical temperature measurements that are independent of the surface emissivity of the object being sensed. In one of the exemplary embodiments disclosed herein, a plurality of spectral radiance measurements at a plurality of wavelengths is received from a surface of an object being measured. The plurality of the spectral radiance measurements is fit to a scaled version of a black body curve, the fitting comprising determining a temperature of the scaled version of the black body curve. The temperature is then output. The present disclosure is not to be construed as limiting and is instead directed toward all novel and nonobvious features and aspects of the various disclosed embodiments, alone or in various combinations and subcombinations with one another.Type: GrantFiled: November 5, 2013Date of Patent: April 4, 2017Assignee: UT-Battelle, LLCInventors: Dennis Duncan Earl, Roger A.

Patent number: 9504973Abstract: Particulate matter is dispersed in a fluid material. A sample including a first material in a fluid state and second material comprising particulate matter are placed into a chamber. The second material is spatially dispersed in the first material utilizing EMAT force. The dispersion process continues until spatial distribution of the second material enables the sample to meet a specified criterion. The chamber and/or the sample is electrically conductive. The EMAT force is generated by placing the chamber coaxially within an induction coil driven by an applied alternating current and placing the chamber and induction coil coaxially within a high field magnetic. The EMAT force is coupled to the sample without physical contact to the sample or to the chamber, by another physical object. Batch and continuous processing are utilized. The chamber may be folded within the bore of the magnet. Acoustic force frequency and/or temperature may be controlled.Type: GrantFiled: March 14, 2013Date of Patent: November 29, 2016Assignee: UT-BATTELLE, LLCInventors: Roger A.

Patent number: 9316078Abstract: Induction shearing may be used to cut a drillpipe at an undersea well. Electromagnetic rings may be built into a blow-out preventer (BOP) at the seafloor. The electromagnetic rings create a magnetic field through the drillpipe and may transfer sufficient energy to change the state of the metal drillpipe to shear the drillpipe. After shearing the drillpipe, the drillpipe may be sealed to prevent further leakage of well contents.Type: GrantFiled: March 15, 2013Date of Patent: April 19, 2016Assignee: TRANSOCEAN INNOVATION LABS LTDInventors: Gerard M.
