  • Device for marking out buried objects
    Patent number: 8981903
    Abstract: A method and apparatus for marking the location of a buried object in which the location of the buried object is determined and a barhole driver or plunger bar having a detachable plug element and a marking material for marking the location of the buried object is driven into the ground proximate the location of the buried object. The detachable plug element detaches from the plunger bar as the plunger bar is removed from the ground, leaving a substantially continuous path of the marking material in the ground extending substantially continuously from proximate the detachable plug element to the ground surface.
    Type: Grant
    Filed: May 5, 2010
    Date of Patent: March 17, 2015
    Assignee: Gas Technology Institute
    Inventors: Nickolas Daniels, Christopher Ziolkowski, Frank Hennessey
  • Method and apparatus for underground line crossing detection
    Patent number: 8555722
    Abstract: A method and apparatus for detecting contact between an underground electric wire conduit and an underground utility pipeline in which a detectable signal is applied to an electric line wire disposed within the underground electric wire conduit and the underground utility pipeline is monitored for a presence of the detectable signal. When there is a contact between the underground electric wire conduit and the underground utility pipeline, the signal applied to the electric line wire is detected by a suitable signal detector disposed on the surface of the utility pipeline and/or within the utility pipeline.
