  • On-line reactant analysis system
    Patent number: 5507935
    Abstract: A reactant monitoring system for monitoring certain properties of, e.g. a BHP reactant solution is provided. Such system incudes a diagnostic conduit loop having one or more sensors in the conduit to measure, e.g. pH and/or ORP of such solution. The solution is pumped through the conduit loop by a pump and the sensors are preferably mounted in the loop, upstream of such pump. The sensors are made of inert materials relative to the monitored solution in the loop, which solution is returned to its source after testing.

  • Oxidation resistant fine metal powder
    Patent number: 4833040
    Abstract: A fine iron powder, being a carbonyl iron powder is electrolessly plated with an oxidatively resistant metallic coating. The coating is obtained from a bath containing nickel and copper salts. Oxidation resistance is improved at temperatures greater than 100.degree. C. Products containing these fine powders include liquids to provide increased oxidation resistance for coating a substrate, and articles formed by such powdered metals with or without other materials, such as ceramic or refractory materials.
