  • Field assembled gas riser
    Patent number: 5590914
    Abstract: A field assembled gas riser includes an adapter having plural inner grooves that receive the outer surface of a plastic gas line as it is plastically deformed by axial insertion of a stiffener into the gas line. The gas line is terminated at a desired location, the adapter slid over the terminated end, and a stiffener manually inserted into the gas line. Continued axial advancement of the stiffener acts as a mandrel to plastically deform the gas line into the grooves and provide a secure, sealed arrangement.

    Date of Patent: June 5, 1990
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Paul J. Berrigan, Michael J. Brennan, Jr.
  • Device for automatically ascertaining capacitor breakdown voltage
    Patent number: 4906939
    Abstract: Test fixtures, each being adapted to receive a capacitor, are connected through a relay network to a time variable high voltage source. Predetermined relays are energized in a predetermined sequence to connect a given capacitor to the source. A high voltage signal having a predetermined waveform is applied to the capacitor associated with an energized relay. When the current through the given capacitor exceeds a threshold, the voltage value then being applied to the capacitor determines the breakdown voltage of the capacitor.
