Abstract: A method for analysis of complex spatio-temporal data within a dynamic system that includes spatial positions and fields, at least a portion of which are interacting, includes determining values of mean field at every spatial position, determining spatio-temporal eigenmodes in spatial-frequency space assuming interacting fields, and determining spatial and temporal interactions between the eigenmodes. The resulting display indicates space/time localization patterns that are indicative of connectivity within the dynamic system.

Abstract: An efficient electrolytic recovery system, having several safety mechanisms, for recovering precious metals from a liquid medium is described. The system includes at least oen electrolysis cell unit having a plurality of reticulate metal foam cathodes. The system of the invention will efficiently recover such precious metals as Au, Ag and Pt. The system may also include a pH adjust means and a means for oxidizing cyanide in the liquid medium.

Abstract: A method of continuously producing a one-side-only zinc coated ferrous metal strip initially having zinc coated on both wide surfaces, as by differentially hot-dip coating, and with the zinc on one of the wide surfaces being in the form of a thin film which is transformed into a thin zinc-iron intermetallic layer by applying heat to only the wide surface of the strip having the zinc in the form of a thin film and abrading the surface of the intermetallic layer thus formed by brushing to effect complete removal thereof, leaving the other wide surface of the strip coated with zinc.
