Abstract: Lower weight shielded cable assemblies with an enhanced level of shielding effectiveness, e.g. in the range of 0.1 MHz to 20 GHz, comprising a core of at least one insulated conductor element overwrapped with metallized fabric, e.g. characterized as having a surface resistivity less than 100 milliohms/square or as being a metallized fabric coated with at least a layer of copper having a metal density of greater than 50 grams/square meter. Cable assemblies can employ a shielding subassembly comprising braided wire and one or more layers of copper-metallized fabric where the shielding subassembly has a transfer impedance at 10 MHz of less than 50 mo/m. For example, it has been found that cable assemblies employing a four layer wrap of certain metallized fabrics can provide up to 20 decibels improvement in shielding effectiveness over a wide range of frequencies with a 74 percent reduction in weight compared to a standard wire braid/foil laminate shield.

Abstract: Nickel and cobalt are reversibly extracted from nickel and cobalt bearing aqueous solutions using solvent extraction techniques by contacting the aqueous solution with a hydrocarbon solvent containing a N-alkylalkanohydroxamic acid having at least about 8 carbon atoms.

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.
