  • Infrared communication repeater architecture
    Patent number: 5563728
    Abstract: A diffuse infrared communication link provides for communication directly between nodes each having a transceiver. A repeater may be present to facilitate communication. Each node is automatically reconfigurable between operation with or without a repeater. When a repeater is present each node automatically ignores any transmission by another node.
    Type: Grant
    Filed: February 22, 1991
    Date of Patent: October 8, 1996

  • Lid construction for a heating vessel and method of use
    Patent number: 4808205
    Abstract: A multilayered, cooled metal lid for a heating vessel has a main support plate fabricated from low carbon steel and a chromium steel overlay that is exposed to the hot interior portions of the vessel. The chromium steel overlay has a chromium content by weight of approximately 10 to 25 percent.

  • Glass batch feed arrangement with directional adjustability
    Patent number: 4728352
    Abstract: A pulverulent batch stream is fed into a liquefying vessel by means of an angled feed tube so as to direct the stream tangentially onto side wall portions. The tube may be rotated so as to change the location onto which the batch stream is impinged.

  • Glass batch transfer arrangements between preheating stage and liquefying stage
    Patent number: 4726830
    Abstract: In an arrangement for preheating and liquefying glass batch materials or the like, the material is transferred from the preheater to the liquefying vessel by conveyor means that isolates batch material from exhaust gas and permits feeding of the batch material to selected regions of the liquefying vessel.

  • Ablation melting with thermal protection
    Patent number: 4668271
    Abstract: In a method and apparatus for liquefying material such as glass batch, primary thermal protection for the vessel is provided by a lining of the batch material, with secondary protection being provided by forced cooling of a minor portion of the vessel in regions and at times when the primary protection is irregular.
