Abstract: This invention relates to an improved reuseable bulk shipping container for the transport of liquids, semi-liquids, semi-solids, pastes and the like. The container has a pallet-type base structure including a drain and flow regulation valve assembly provided with a quick connect-disconnect coupling for connection to an exterior pumping source and a base retainer ring located on the base structure adapted to support the base of a side structure. The side structure includes removable metal panels or the like, and support structure to maintain the panels in a cylindrical form. A disposable inner liner is provided for containing the product. A top liner support bar, a top retaining ring cover structure and connecting rods are provided to secure the structure to the pallet-type base structure.

Abstract: A process for recovering the metals manganese, nickel, and cobalt from their oxides and silicates in which the metal oxide or silicate is heated with ferric chloride in the absence of air and in the presence of a volatility depressant salt which is preferably an alkaline metal chloride or ammonium chloride to form the soluble chloride of the metal followed by dissolving the metal chloride from the residue and recovering the metal from the chloride solution by electrolysis, cementation or other standard recovery procedure.

Abstract: The desulfurization of both inorganic and organic sulfur constituents of coal by treating the coal in a liquid fused salt bath in the presence of chlorine to react the sulfur containing constituents with chlorine to form chlorides and elemental sulfur. The liquid fused salt bath is comprised of the chlorides of ferric iron, alkali metals, alkaline earth metals, ammonia, and zinc.

Abstract: This disclosure deals with a pipe sleeve used to form a hole when pouring a concrete slab or the like. The pipe sleeve includes a tubular elongated side wall having an end wall closing one end thereof and a radially outwardly extending flange at the other end thereof. Longitudinally extending ribs are formed on the outside surface of the side wall, and a plurality of grooves are formed in the inner surface of the side wall. The side wall is tapered, and due to this taper, the pipe sleeves may be compactly stacked for storage or for shipping purposes. The sleeve may be used either in its original length or, if desired, in a shorter length by cutting the side wall to a desired length and then telescoping the two cut sections together. When stacked for shipping or storage, the ribs are located in the grooves but when two cut sections are telescoped, the ribs are out of the grooves and tightly bind the two sections together.
