Abstract: A portable toilet is mounted on a skid. The skid has a pair of horizontal members with a terminal end with a vertically oriented hole. A leveler affixed to the horizontal member at the terminal end via a connector with a first vertical hole laterally spaced away from a second vertical hole. An anchor bolt is associated with the first vertical hole and engageable with the vertically oriented hole in the skid's horizontal member, thereby fastening the leveler to the toilet. A leveler bolt is threadingly engaging the second vertical hole for movement in a vertical direction in relationship to the toilet; and a foot associated with a lower terminal end of the leveler bolt. Whereby when the leveler is anchored to the skid and the leveler bolt is engaged with the foot, the portable toilet may be leveled by movement of the leveler bolt.

Abstract: The description relates to a process for reducing acid plume from stacks from coal-fired combustors operating at varying loads, which have typically been treated by back-end calcium carbonate (limestone) which has not been able to effectively control visible acid plume as power is ramped up from low load. According to the process, as high sulfur and high iron coals are burned in a combustor, magnesium hydroxide slurry is introduced into hot combustion gases in or near the combustion zone. And, during ramp up to high load from a period of operation at low load, additional magnesium hydroxide is introduced into an intermediate-temperature zone.

Abstract: A stepwise method of preparing homogeneous mineral granules for agriculture by coreaction of commodity acids and bases which have properties to chemically form a transient fluid adhesive which will harden to form a strong granule binding cement. Water may be added to improve the effectiveness of the adhesive. The transient fluid adhesive is comminuted by mechanically shearing, then particulate mineral solids are admixed mechanically to form a mass of plastic globules which is rolled to form spheroid granules and the fluid adhesive hardens to form the hardened binding cement. The method provides substantially dust-free and attrition resistant animal feed supplement, and plant food fertilizer and micronutrient granules. The commodity acids and bases include aqueous and anhydrous mineral and alkyl carboxylic acids and alkali and alkaline earth bases.

Abstract: The present invention teaches a technique and provides for apparatus eminently useful for the econimic recovery of Fe, Zn, and S from waste galvinizer sulfuric acid and crystals of iron sulfate and zinc sulfate.

The effecting of the instant technique requires only a minimal amount of relatively inexpensive equipment and is simply and easily placed into practice by, for example, sparging anhydrous ammonia into a stirred tank of waste acid until the Ph is elevated to about 10. Air can be sparged through the resulting slurry to oxidize the iron in the acid. After a proper incubation period, the desired stable product, e.g.

Abstract: The process allows essentially all of the nitrogen and P.sub.2 O.sub.5 values in the treated black ammonium polyphosphate liquid to be recovered in the form of valuable clarified product. In the process, a heel of black liquid fertilizer is first clarified by a prior-art procedure using flocculants. The improvement over the prior art picks up with the byproduct tops which is then diluted with the water of formulation required to dissolve additional amounts of ammonium polyphosphate melt. This diluted liquid is filtered, the filter cake containing upwards of 99 percent of the undesirable black carbonaceous material is discarded, and the clear filtrate, which contains essentially all of the nitrogen and P.sub.2 O.sub.5 originally in the tops, is then used in lieu of the prior-art water of formulation to dissolve additional ammonium polyphosphate melt to produce more black ammonium polyphosphate liquid.
