  • Device for measuring subsurface temperatures of liquid bodies, useful for determining optimum fishing locations
    Patent number: 4883365
    Abstract: The device of the invention consists of a temperature sensitive device embedded in a matrix which provides a useful heat flow pattern. Apparently the device exploits the difference in the thermal conductivities of air versus other media, such as water or slurries, to function. Plastics are the preferred matrix material for most applications. The insulating and non-wettability properties of plastics may contribute to the observed useful properties as well. The chemical resistance of certain plastics can provide additional useful variations. The invention is especially useful as an aid to fishing. The device readily and simply identifies which waters have the best chance of containing fish. Other examples are municipal drinking water tanks, liquid cargo tanks, oil and water wells, etc.

  • Solvent extraction of cobalt using hydroxamic acids
    Patent number: 4882132
    Abstract: Cobalt is reversibly extracted from cobalt bearing aqueous solutions using solvent extraction techniques by contacting the aqueous solution with a hydrocarbon solvent containing a N-alkylakanohydroxamic acid having at least about 8 carbon atoms. A new class of cobalt complexes is also provided.

  • Oxidative dissolution of gallium arsenide and separation of gallium from arsenic
    Patent number: 4759917
    Abstract: Gallium is recovered from gallium arsenide by reacting and dissolving the gallium arsenide with an oxidant and a complexing agent, especially with water insoluble hydroxamic acids with mild conditions, e.g. with aqueous hydrogen peroxide and mild temperature, to effect separation of gallium hydroxamic acid chelates from water soluble arsenic compounds.

  • Gallium complexes and solvent extraction of gallium
    Patent number: 4741887
    Abstract: Gallium is extracted in the presence of other metals from gallium bearing aqueous solutions, by contact with organic solvent containing N-organo hydroxamic acids, particularly at described acid and alkaline pH ranges; and recovered from the organic solvent. New gallium complexes and certain N-organo hydroxamic acids are also provided.
