Publication number: 20240110895Abstract: A testing device includes a first member to be positioned on one surface of a part to be tested. A second member to be positioned on an opposed surface of the part to be tested. One of the first and second members have an ultrasonic transmitter and the other has an ultrasonic receiver. At least one of the first and second members have at least one magnetic element and the other of the first and second member have at least one magnetic or at least one ferromagnetic metallic element such that when one of the first and second members moves along the surface of the tested part the other of the first and second members will move along an opposed surface with the one of the members.Type: ApplicationFiled: October 3, 2022Publication date: April 4, 2024Inventors: Douglas McNeil, Jeffrey J. Allen, Joyel Schaefer, Mark R. Gurvich, Michael J. King, Brayton Reed

Publication number: 20240110847Abstract: A method of testing a part includes placing a first member on a part to be tested. A second member is placed on an opposed surface of the part. One of the members has an ultrasonic transmitter and the other has an ultrasonic receiver. At least one of the members has at least one magnetic element and the other has at least one of a magnetic element or a ferromagnetic metallic element which is attracted to magnets. One of the members moves along the surface of the part such that magnetic attraction causes the other to move along the opposed surface of the part with the one of the members. A controller causes an ultrasonic signal to be sent from the transmitter through the part to be tested which is received by the receiver and then analyzed by an ultrasonic testing machine.Type: ApplicationFiled: October 3, 2022Publication date: April 4, 2024Inventors: Douglas McNeil, Jeffrey J. Allen, Joyel Schaefer, Mark R. Gurvich, Michael J. King, Brayton Reed

Patent number: 11096248Abstract: The present disclosure is directed toward a heater that includes a resistive heating element, a first power pin, and a second power pin. The first power pin forms a first junction with a first end of the resistive heating element, and the second power pin forms a second junction with the second end of the resistive heating element. The second power pin includes a first lead wire and a second lead wire. The first lead wire forms the second junction with the second end of the resistive heating element and defines a first conductive material. The second lead wire forms a primary sensing junction with the first lead wire at a first reference area, and defines a second conductive material different from the first conductive material to measure a temperature at the first reference area based on a voltage change created by the primary sensing junction.Type: GrantFiled: April 11, 2018Date of Patent: August 17, 2021Assignee: Watlow Electric Manufacturing CompanyInventors: Terry Colhour, Douglas Schaefer, Jeremy Ohse, Jacob Burnia, Eric Ellis, Louis P. Steinhauser

Publication number: 20170093843Abstract: In a method for certifying a website to be malware-free and owned by an entity fulfilling a trust criterion, such as a chartered financial institution, a request can be received via a network. The request can specify a domain name and a site map of the domain name. A processor can validate that all Uniform Resource Locators (URLs) in the site map are devoid of malware and that the domain name is owned by a chartered financial institution. A network-accessible document can certify that the domain name and all URLs in the site map are devoid of malware and that the domain name is owned by the chartered financial institution. The URLs can be validated periodically, and the document can be updated periodically. The document can be a single XML file stored in a centralized location, and can include validations from multiple website owned by respective financial institutions.Type: ApplicationFiled: September 25, 2015Publication date: March 30, 2017Inventor: Derick Douglas Schaefer

Publication number: 20050167440Abstract: A coupling for connection of a tube comprises a coupling housing which includes a first end into which the tube is inserted, a clamping ring which is positioned in the coupling housing against a first conical surface, a sealing ring which is positioned in the coupling housing, and a return ring which is positioned in the coupling housing between the clamping ring and a second end of the housing adjacent a second conical surface that is tapered opposite to the first conical surface. The return ring is expandable and comprises a central aperture which is smaller than the external diameter of the tube. Accordingly, when the tube is pushed into the coupling housing and forced through the return ring, the return ring will expand and move along the second conical surface.Type: ApplicationFiled: July 14, 2004Publication date: August 4, 2005Inventors: Doug Huffer, Fred Lowery, Gary Petersen, Keith Gausmann, Samuel Marino, Gary Myers, Jamison Float, Jay Perkins, Steve Pever, Robert Hayes, Michael Kopezewski, Paul Hsu, Douglas Schaefer, Brent Burchfield, Jeffrey DeBord
