Patent number: 10087634Abstract: A method includes providing a production line configured for continuous fabrication of polymer or predominantly polymer roofing boards by setting and expansion of precursor materials on a conveyor. A first polymer or predominantly polymer material foam precursor is dispensed to the production line, and allowed to rise and at least partially set to form a foam core layer for an insulation board, the foam core layer for the insulation board having a first density. A second polymer or predominantly polymer material foam precursor is dispensed to the production line and allowed to rise and set to form a core layer for a cover board, the foam core layer for the cover board having a second density greater than the first density. The combined thickness of the foam core layer for the insulation board and the core layer for the cover board is set by constraining the expansion of the combined foam precursors using a downstream forming conveyor disposed above the rising foam precursors.Type: GrantFiled: January 18, 2018Date of Patent: October 2, 2018Assignee: Johns ManvilleInventors: Walter Alexander Johnson, Joel Evan Hazy, Duane Paradis, Christopher J Griffin, Raymond C Swann, Brad C Burdic

Publication number: 20180246988Abstract: The present invention addresses deficiencies of the art with respect to collaborative computer networks consisting of mixed data, control functions, analysis functions, and sensors in complex systems of systems. The method involves a database framework for representing complex heterogeneous characteristics of processes, systems, and systems of systems that feature many to many interrelationships. The homoiconic graph framework takes the form of an executable graph database, which is often faster for associative data sets, and maps more directly to object-oriented computer applications for large-scale operations. The invention provides a method to execute the graph database, in that the graph comprises nodes that are both data fragments and executable components. The graph is characterized as one or more homoiconic or executable graph frameworks, to distinguish this unique feature from the concept of a graph database, which generally is a repository of connected data only.Type: ApplicationFiled: April 16, 2018Publication date: August 30, 2018Inventors: Caryl Erin Johnson, Kay E. Aikin, Alexander Johnson, Trevor Gionet, JR.

Publication number: 20180136291Abstract: A magnetometer containing a crystal sensor with solid-state defects senses the magnitude and direction of a magnetic field. The solid-state defects in the crystal sensor absorb microwave and optical energy to transition between several energy states while emitting light intensity indicative of their spin states. The magnetic field alters the spin-state transitions of the solid-state defects by amounts depending on the solid-state defects' orientations with respect to the magnetic field. The optical read out, reporting the spin state of an ensemble of solid-state defects from one particular orientation class, can be used to lock microwave signals to the resonances associated with the spin-state transitions. The frequencies of the locked microwave signals can be used to reconstruct the magnetic field vector.Type: ApplicationFiled: November 8, 2017Publication date: May 17, 2018Inventors: Linh M.

Publication number: 20170348835Abstract: A torque fastening system and method for applying torque to secure a fastener, includes actuating a torque tool to provide an initial command torque value to the servo drive of an electric motor for applying torque to a fastener. The initial command torque value is less than a target command torque value corresponding to a desired maximum target torque value entered by an operator. The torque fastening system operates at the initial command torque value to rotate a threaded fastener. Thereafter, in response to a spike in torque that corresponds to a decrease in motor speed, the torque tool output changes from the initial command torque value to a jump command torque value having a greater power value to increase torque applied by the torque tool to a fastener. The command torque value is ramped from the jump command torque value toward the target command torque value to increase the torque provided by the torque tool.Type: ApplicationFiled: June 1, 2016Publication date: December 7, 2017Inventors: Jeffrey Gerard Skelly, George T. Prince, Rodolfo Favian Gomez, Richard Carlton Steinfeldt, Mark Alexander Johnson, Christopher John Kolbe
