  • Ionic liquid temperature sensor
    Patent number: 6749336
    Abstract: A temperature sensor having a capillary tube or stem, sealed at both ends, with a thin bore defined therein is applied to the measurement of temperatures having a range of about −100° to +400° Centigrade. A bulb comprising a liquid reservoir, is provided at one end of the capillary tube, in liquid communication with the bore, and is generally filled with an ionic thermometric liquid. In the operation of the temperature sensor, temperature is measured by the height of the liquid in the bore.

  • Production of metal/refractory composites by bubbling gas through a melt
    Patent number: 6343640
    Abstract: A method of making metal/refractory composites includes bubbling a reactive gas through a melt to form a foam including refractory particles. In continuous mode, the foam is separated from the melt and the melt replenished. Composites of lightweight metals reinforced with discontinuous refractory ceramic particles can be efficiently and economically produced.
