Abstract: Bar soap for personal use having a structural center selected from an open celled sponge material, or woven or non-woven organic filamentary material, which is preferably fully soap-impregnated. The sponge core is revealed after the soap bar is reduced to a sliver, providing support, preventing breakage and making washing more effective and reducing wastage. Water soluble oxycellulose polymers may be used. The sponge may be configured in the form of a character or animal shape for children. The core may extend to at least one surface and can be configured to provide a hanger support. The core permits dipping to build up the bar, and layered soap of different compositions or colors is disclosed.

Abstract: A multi-stage, batch or continuous, manual or automated process and apparatus for safely depressurizing, de-capping (decrimping plus pulling caps), and recycling aerosol cans, propellants, solvents, chemicals, dip tubes, and can tops. The apparatus includes a synchronized sorting and loading unit for guiding the cans onto an advancing line. The cans are first depressurized by a vacuum head unit comprising a vacuum seal and a reciprocable hollow needle which punctures the can recessed top cap and removes the propellants by suction for later reuse or disposal. The cans are advanced to a decapping unit where the cap member is removed by decrimping to crack the seal followed by being vertically pulled off without damage to the can's rolled lip.

Abstract: Combination mailer comprising postcard-weight stock having therein at least two areas, a first right hand area for an address and postage and a left hand area which includes a partially perfed (die cut) index card which may be removed from the combination mailer. The index cards may be standard small size or a larger size depending on the size of the mailable card used. The index card may be oriented horizontally or vertically. A vertical boundary between the left and right side areas is defined by a scoring, perf line, printed line or dashes in order to assist in removing the index cards from the mailer. Only partial perforations are used to define the index card margins to prevent the mailer from being folded, mutilated, lost or delayed in the mailing. Microperfs are preferred. Preferably, the index card is oriented vertically with only the T-shaped notches along the bottom margin being perfed out, leaving the bottom margin or top margin to be cut with scissors.

Abstract: Process for control of SO.sub.x emissions from copper smelter operations involving pyrometallurgical reduction of copper ores to elemental copper in which the gases from reverberatory furnaces, roasters, and/or converters are scrubbed with a sodium alkali sorbent to produce sodium sulfate and sulfite wastes. The cleaned flue gases are exhausted to the atmosphere. The waste sodium sulfate/sulfite material is then reacted with excess acid from the smelter acid plant and ferrous ion-rich barren solution from the associated cement copper operations to produce co-precipitated double salts of sodium ferric hydroxy-disulfates and/or sulfites (SFH), having low water solubility and being suitable for landfill type disposal without posing serious water pollution problems. This disposes of the sodium sulfite/sulfate waste materials from the air pollution control process and also strips the barren solution of iron prior to its recycle to heap or dump leaching operations.

Abstract: Process for insolubilizing water soluble wastes from alkaline sodium or ammonium type sulfur dioxide control systems used in conjunction with industrial or power plants. The sodium or ammonium sulfite or sulfate wastes are reacted in solution with ferric ions and sulfuric acid to produce an insoluble basic, hydrous or anhydrous, sodium and/or ammonium hydroxy ferric sulfate or sulfite compounds of the generic type M.sub.v (Na, NH.sub.4).sub.w Fe.sub.x (SO.sub.u).sub.y (OH.sub.z)nH.sub.2 O, wherein M is selected from an alkali metal other than sodium, or an authigenic metal or other cation present in industrial or power plant wastes, v is selected from zero to six, w is selected from zero to five, x is selected from zero to six, y is selected from one to five, u is 3 and/or 4, z is selected from zero to 12, and n is selected from zero to 20. Principal end product compounds include Natrojarosite, Ammoniojarosite, Metasideronatrite, Sideronatrite, Depegite, Rosarite, Iriite, and mixtures thereof.

Abstract: Method for disposal of water soluble sodium sulfur oxide-containing wastes resulting from industrial processes producing fly and/or bottom ash from fossil fuel utilization and waste or excess sodium sulfur oxide compounds, particularly disposal of sodium sulfite and/or sodium sulfate resulting from wet or dry sodium alkali scrubbing of tail or flue gases to reduce SO.sub.x emissions therefrom as from smelters, power plants, paper plants, glass plants and industrial boiler operations. Process involves mixing sodium sulfur oxide wastes with an alumina and silica-containing fly ash and/or bottom ash, forming an agglomerate, such as a pellet or briquette, and sintering in the range of about (1000.degree.-2300.degree.F). The resultant sintered particle shows lower solubility than the current standard of calcium sulfate, being 10.sup..sup.-2 to 10.sup..sup.-4 as soluble as the starting sodium sulfur oxides, has increased density (as high as 2.
