  • Method and apparatus for determining the health and remaining service life of austenitic steel reformer tubes and the like
    Patent number: 9546982
    Abstract: Testing methods and apparatus for testing the health of steel tubes used in reformers and other tubes and pipes used in other high temperature applications. The method includes the steps of transmitting two sinusoidal electromagnetic signals, each having a different frequency F1 and F2, into the reformer tube, receiving a response signal, and analyzing the received response signal's intermodulation frequencies to determine the state of the steel reformer tube.
    Type: Grant
    Filed: December 10, 2013
    Date of Patent: January 17, 2017
    Assignee: ArcelorMittal
    Inventors: Michael A. Masleid, Zofia E. Niemczura, George B. Tsvik

  • Wireless information transmission system
    Patent number: 5040175
    Abstract: A wireless local area network (10) includes a plurality of stations (12) adapted to transmit and receive message packets via a distribution system (30). In a time division multiplexing embodiment the network (10) operates using successive timing frames (FR1, FR2, etc.) each consisting of three timing intervals (T1, T2, T3). During the first timing interval (T1) the distribution system (30) normally transmits synchronizing packets (HBT), to which a station (12) desiring to transmit responds by transmitting an information packet during the next second timing interval (T2). During the subsequent first timing interval (T1), the distribution system (30) retransmits the received information packet.
