  • Fixture adapted for evacuating and filling heat pipes and similar closed vessels
    Patent number: 4881580
    Abstract: A table carries guides for receiving and guiding a heat pipe. The heat pipe has a fill port which contains a valve. The heat pipe is thrust against the seal face of a block for evacuating and filling the fluid chamber of the heat pipe. A hex driver passes through the block and engages the valve to open and close the valve while the fill port is sealed from the atmosphere.
    Type: Grant
    Filed: July 18, 1988
    Date of Patent: November 21, 1989
    Assignee: Hughes Aircraft Company
    Inventors: John E. Murphy, Joseph E. Snyder, William T. Gardner

  • Method for measuring the thickness of a refractory in a metallurgical apparatus
    Patent number: 4269397
    Abstract: A method for measuring the thickness of a refractory laid-up against the interior surface of the steel shell of a metallurgical apparatus includes placing at least one monitoring device in a critical wear area of the apparatus in a manner such that the free end of the device is at a known distance from the hot face of the refractory and the confined end extends beyond the outer surface of the steel shell. The device is connected to an electronic time-domain reflectometer by electrical connecting means. Timed pulses are generated and impressed in the device by the instrument and reflections of the pulses are received by and are visually displayed on the reflectometer. The length of the device appears on the display as a straight line bounded by two inflections. The straight line is indicative of the thickness of the refractory.The device includes a metallic conductor coaxial with an outer metallic sheath and separated therefrom by a refractory having a desired dielectric constant.
