  • Patent number: 5032372
    Abstract: An improved dilute phase chlorination procedure characterized by providing extremely finely divided oxygen-containing metallic material and a carbonaceous material co-milled together to a particle size size of less than 20 microns. The finely divided charge material is introduced into a tubular reaction zone, preferably at the bottom, with the gaseous chlorination agent where reaction occurs at a temperature above 800.degree. C. for a period of time sufficient to fully react the chlorinating agent in a single pass. Metal chloride is recovered from the tubular reactor and, most advantageously, there is little or no need to separate any dusty unreacted solid material from the off-gases for recycle to the chlorination zone.

  • Patent number: 5031456
    Abstract: The present invention provides a method of detecting a void-related fault in a metal or metal alloy component. The method comprising filling the fault with a fluid, preferably liquid; treating the component and fluid so as to produce thermal-excitation in the component and fluid; and thereby cause a detectable acoustic signal. The detection of the signal detects the presence of a void-related fault. The invention also provides a method of locating and characterizing a void-related fault which comprises detection of the fault as described, measuring the parameters of the acoustic signal and the conditions for producing the signal, and correlating the parameters and conditions with the location and characteristics of the fault. The invention is particularly useful for the detection of microbiologically induced corrosion (MIC). The invention also concerns a method of evaluating a component for the severity of a void-related damage.

  • Patent number: 4999336
    Abstract: There is provided a substantially fully dense powdered metal composite comprising a highly conductive metal or metal alloy matrix having dispersed therein discrete microparticles of a refractory metal oxide and discrete macroparticles of a mechanical or physical property-conferring additive material. The respective components undergo minimal alloying or interdispersion because sintering is not utilized in forming the composite. These composites are characterized by high thermal or electrical conductivity and a desired property (controlled thermal expansion, high strength, wear and arc erosion resistance, or magnetic) attributable to the composite forming material, like refractory metal, alloy, or compound. The composites are useful in forming lead frames for integrated circuit chips, electric lamp lead wires, electrical contact members, and discrete component leads.
