摘要： Stable suspensions can be made from acidic metal salt solutions and finely divided acid-insoluble solid particles that have a particle size of less than twenty-five microns, preferably less than ten microns, and most preferably, about one micron. These suspensions can be used to treat surface waters to remove organic materials therefrom. The suspension forms a floc that includes the solid particles and organic materials, which floc rapidly settles out of solution, leaving purified water as the supernatant liquid.

摘要： The addition of an effective amount of a liquid modified diethanolamide which is suitably a reaction product of cocoamide and phthalic anhydride to a calcium chloride composition, which can be a brine solution or a solid, reduces the amount of corrosion of metals by the resulting composition. The calcium chloride/diethanolamide composition can be used as a deicer composition.

摘要： Shrimp and other seafood can be preserved to extend their freshness shelf life by immersing them in an aqueous solution prepared by dissolving a dry mixture containing sodium metabisulfite with from 30 to 50% by weight of sodium sulfite. These solutions have excellent preservative action yet have very little or no odor of sulfur dioxide. The solutions are useful in a concentration of up to about 3% by weight.

摘要： The action of the bacterium Nitrobacter agilis to oxidize nitrite ions to nitrate ions in aqueous solutions is well known. We have found that if the nitrite ion concentration in solution is maintained at a level of at least 2.5 percent by weight and higher, that the activity of this bacterium is completely inhibited and the nitrite salt solutions remain stable over long periods of time.

摘要： An improved hydrator apparatus for the transfer and slurry storage of dry particulate matter comprises a sealed solvation hopper chamber in combination with a liquid driven eductor and equipped to be connected to a storage container as provided. The improvement resides in the provision of a flushing device that functions periodically and automatically in timed intervals, and without the need to shut down the operating hydrator, to remove solids accumulation in the hopper chamber.

摘要： Sodium (bi)sulfites are produced by the steps of:(a) introducing a stream of aqueous sodium carbonate into the top end of a main packed column reactor;(b) introducing a stream of sulfur dioxide gas into the top end of the main packed column reactor concurrently with the stream of aqueous sodium carbonate;(c) allowing the aqueous sodium carbonate and sulfur dioxide to cocurrently flow downward from the top end of the main packed column reactor to the bottom of the column in a cocurrent flow, during which flow reaction occurs between the aqueous sodium carbonate and the sulfur dioxide to produce sodium (bi)sulfite; and(d) recovering the product sodium (bi)sulfite and a gas stream containing any excess sulfur dioxide from the bottom of the main packed column reactor. The product (bi)sulfite can be separated from the gas stream in a separate receiving vessel and then the gas is sent to a scrubber to remove residual SO.sub.2. The scrubber may be a second packed column reactor operating with cocurrent flow.

摘要： An elevated roadway for use with a self-propelled continuous haulage unit in underground mining consists of a multiplicity of substantially identical roadway units joined together end to end. Each unit has a pair of elongated bottom side beams joined by bottom cross beams, columns arranged in laterally opposite pairs and supported on the side beams and a pair of elongated track members supported on the upper ends of the columns and defining a track for trams to move over the roadway above the haulage unit. Longitudinal brace beams and transverse brace beams join the columns. The durability and rigidity of the unit is enhanced by diagonal brace beams connecting selected ones of the columns and by gussets at each joint between the bottom side beams and the bottom transverse beams.

摘要： Permanganate based fabric bleaching processes, such as stone-washing processes, are substantially improved by utilizing a reducing composition comprising a metabisulfite and a sulfite in the washing step. The relative amounts of metabisulfite and sulfite in the reducing composition are selected so as to substantially eliminate the odor of sulfur dioxide during the washing step at the particular temperature selected. For washing temperatures of 100.degree.-140 .degree. F. the preferred weight ratio of sodium metabisulfite to sodium sulfite is 7:3, which produces a reducing composition having a pH of 6.2 (in a 5% by weight solution). Such a composition not only allows operation at elevated temperatures without an odor of SO.sub.2, it also allows a reduction in the washing time and in the amount of reducing composition used.
