Abstract: A modular desktop organizer and system including a rectangular base with a tall superstructure and shallow side trays. The superstructure includes a U-slot for holding an upright smartphone with an inductive charger, and a deep cup for holding pens, scissors, and accessories. The base includes a channel-shaped tablet holder at the back. The base is electrically powered and includes USB ports. The modular components have a self-centering bias by way of a bottom bulge with a rounded periphery that nests within the top of another modular component having a complementary rounded lip. The modular components can be stacked to two, three or more levels high in an aligned and neat fashion due to the self-centering bias.

Abstract: The present invention is directed to a method for treating a sludge containing substantial amounts of chromium, aluminum, calcium, iron, and phosphorous. The method comprises forming a slurry of the sludge; reacting the slurry with an acid to dissolve substantially all the aluminum and chromium and provide a solids residue comprising mostly calcium sulfate; separating the chromium/aluminum-containing solution from the solids residue; raising the pH of the chromium/aluminum solution to precipitate chromium as chromium hydroxide; and separating the chromium hydroxide from the remaining aluminum-containing solution. The chromium hydroxide is then enriched with an alkali or earth alkali compound and calcined in an oxidizing atmosphere to convert the chromium to a chromate. The calcine is leached in an aqueous medium at a controlled pH to yield a high concentration, high purity chromate solution suitable for producing metallic chromium or a variety of chromium chemicals.
