Abstract: This disclosure teaches synthetic polyurethane sponges manufactured with at least 5% of one or more additives dispersed therein. The additives may be soap, lotions, detergents, pesticides, lanolin, scouring particles, silicone oils, bath oils, or the like or combinations thereof. The sponges' skeletons are developed by reaction of a polyether or a polyester with a suitable isocyanate in the presence of a catalyst with the additives entrapped in voids of the sponges. An additive bearing material, i.e. a carrier material containing the additive is prepared. The carrier material is then mixed into a foam forming reaction mass. By this expedient the additive does not impair desired foam formation. The sponges are provided with high liquid absorbency and fine "hand" by virtue of manufacturing methods and specific catalysts employed.

Abstract: Acid drainage from exposed pyritic material such as coal mine tailings is reduced through the controlled application of anionic detergents which inhibit the bacterium Thiobacillus ferrooxidans. The controlled application of anionic detergent comprises an initial application of anionic detergent in sufficient quantities to satisfy the adsorptive capacity of clay or clay-sized particles overlying the pyritic material coupled with the application of an anionic detergent inhibitor of Thiobacillus ferrooxidans from a slow release matrix containing the inhibitor. The two applications are to intercept infiltrating water up-gradient of the pyritic material or strata. The amount of matrix employed is calculated in accordance with a described formula. The method can be used to reduce acidity in drainage from pyritic mine tailings, coal mines, coal refuse piles and construction sites at which acid drainage is a problem.

Abstract: Water-based hydraulic fluids and metalworking lubricants are disclosed which are thickened with a polyether polyol having a molecular weight of about 1000 to about 75,000 modified with an alpha-olefin epoxide having about 12 to about 18 carbon atoms. Unexpectedly, synergistic thickening results from a combination of said polyether polyol with the components of a water-based hydraulic fluid or metalworking lubricant. The particularly effective components of the hydraulic fluid or metalworking lubricant are the phosphate ester and water-soluble amine corrosion inhibitor components. The hydraulic fluid and metalworking fluids of the invention also contain a water-soluble polyoxyethylated ester of an aliphatic acid and a monohydric or polyhydric aliphatic alcohol, either one or both said acid and said alcohol being polyoxyethylated, a sulfurized molybdenum or antimony compound and a metal deactivator as well as other adjuvants conventional in this art.

Furthermore, in this soap composition, the viscosity is hardly changed with the lapse of time.

Abstract: Gelation and setting of desirably miscible and pumpable aqueous crutcher slurries comprising sodium bicarbonate, sodium silicate and sodium carbonate are retarded and often are prevented by the addition of sodium sesquicarbonate (which serves as a source of sodium carbonate and sodium bicarbonate) after admixing of sodium bicarbonate, sodium carbonate (if added earlier) and sodium silicate.
