Patent number: 11727120Abstract: Technology related to blockchain cybersecurity solutions and a blockchain applicability framework is disclosed. In one example of the disclosed technology, a system is configured to store, in a database, a plurality of cryptographically-signed records of data transmitted between an asset and a utility historian, and store, in a distributed ledger, a respective hash value corresponding to each record of the database. The system can be further configured to verify a selected record by recomputing a hash value corresponding to the selected record and comparing the recomputed hash value to the respective hash value stored in the distributed ledger in correspondence with the selected record.Type: GrantFiled: July 10, 2020Date of Patent: August 15, 2023Assignee: Battelle Memorial InstituteInventors: Sri Nikhil Gupta Gourisetti, Michael E. Mylrea, Craig H. Allwardt, Beverly E. Johnson

Patent number: 11206287Abstract: Technology related to evaluating cyber-risk for synchrophasor systems is disclosed. In one example of the disclosed technology, a method includes generating an event tree model of a timing-attack on a synchrophasor system architecture. The event tree model can be based on locations and types of timing-attacks, an attack likelihood, vulnerabilities and detectability along a scenario path, and consequences of the timing-attack. A cyber-risk score of the synchrophasor system architecture can be determined using the event tree model. The synchrophasor system architecture can be adapted in response to the cyber-risk score.Type: GrantFiled: January 29, 2019Date of Patent: December 21, 2021Assignee: Battelle Memorial InstituteInventors: Seemita Pal, Arun Veeramany, Christopher A. Bonebrake, Beverly E. Johnson, William James Hutton, III, Siddharth Sridhar, Sri Nikhil Gupta Gourisetti, Garill A. Coles

Patent number: 4834650Abstract: The furnace has a hearth which rotates inside a stationary closed chamber and is supported therein on vertical cylindrical conduit which extends through the furnace floor and is supported by a single center bearing. The charge is deposited through the furnace roof on the rim of the hearth as it rotates and is moved toward the center of the hearth by rabbles. Externally generated hot gases are introduced into the furnace chamber below the hearth and rise through perforations in the hearth and up through the charge. Exhaust gases are withdrawn through the furnace roof. Treated charge drops from a center outlet on the hearth into the vertical cylindrical conduit which extends downwardly through the furnace floor to which it is also sealed.Type: GrantFiled: June 14, 1988Date of Patent: May 30, 1989Assignee: Salem Furnace Co.Inventors: James P. Docherty, Beverly E. Johnson, Joseph Beri

Patent number: 4818222Abstract: The furnace has a hearth which rotates inside a stationary closed chamber and is supported therein on circumferentially spaced rollers the shafts of which extend outside the furnace and are cantilevered in bearings. The shafts are sealed to the furnace wall by mechanical and pressurized gas sealing means. The charge is deposited through the furnace roof on the rim of the hearth as it rotates and is moved toward the center of the hearth by rabbles. Externally generated hot gases are introduced into the furnace chamber below the hearth and rise through perforations in the hearth and up through the charge. Exhaust gases are withdrawn through the furnace roof. Treated charge drops from a center outlet on the hearth into a soaking pit which extends downwardly through the furnace floor to which it is also sealed.Type: GrantFiled: June 14, 1988Date of Patent: April 4, 1989Assignee: Salem Furnace Co.Inventors: James P. Docherty, Beverly E. Johnson

Patent number: 4669977Abstract: Apparatus for drying and heating wet particulate materials comprises a furnace with stationary circular hearth and sidewalls and a rotating roof. The hearth is perforated to receive hot gases from a plenum chamber below it, which gases are drawn off from the hearth through conduit openings out of its sidewalls, the major portion of the gases are externally heated, and are returned to the hearth through the plenum chamber. A feed bin is positioned on the roof at its center and through a conveyor feeds charged material onto the hearth through an opening in the roof near its outside edge. Rabbles are mounted in the roof to move the charge toward the center of the hearth as the roof rotates. From the center of the hearth a soaking pit extending through the plenum chamber discharges the heated material.Type: GrantFiled: March 25, 1986Date of Patent: June 2, 1987Assignee: Salem Furnace Co.Inventors: Beverly E. Johnson, William E. Solano

Patent number: 4096038Abstract: Method and apparatus for the heat treatment of volatile containing materials in a rotary hearth type furnace wherein the flue gases emanating from the calciner are employed to create either a positive or negative pressure within the calciner hearth as well as the soaking pit area of the said calciner.Type: GrantFiled: October 1, 1976Date of Patent: June 20, 1978Assignee: Salem Furnace Co.Inventors: Ray E. Kranz, William E. Solano, Beverly E. Johnson
