Abstract: A phosphate-free and silicate-free aqueous alkali composition consisting essentially of water, a water soluble base selected from the group consisting essentially of alkali metal hydroxide, alkali metal carbonate and mixtures thereof, wherein the base is present in an amount sufficient to yield a composition pH of about 11 to about 12 at a composition concentration of about 0.1 wt % to about 1 wt % in a dye bath, and an aminopolycarboxylate sequestrant in an amount sufficient to sequester metal ion impurities and prevent destructive reactive dye hydrolysis when the composition is used to dye fabric in the presence of reactive dye and metal ion impurities. Also disclosed is a dye bath containing the composition and a method of using the composition in reactive dyeing.

Abstract: An apparatus for directing a liquid spray against the interior walls of a vessel from a nozzle spray means comprising a housing mounted externally to a vessel. A spray support assembly is mounted within the housing which includes a spray support assembly having a rigid fluid supply tube and a nozzle spray means mounted to the forward end of the fluid supply tube. A gear rack disposed on an outer surface the tube which extends along a predetermined length of said tube. A drive assembly mounted to the housing for engaging said gear rack and moving said tube into and out of the vessel.

Abstract: A fluid driven tank cleaning apparatus which uses part of the cleaning fluid supplied to the device for lubricating the gear train located in a separate compartment. Passageways are positioned and sized so as to maintain the separate compartment substantially filled with the cleaning solution at a relatively low pressure and flow rate therethrough. The device is constructed to minimize the corrosive effects of cleaning fluid on the moving parts.

Abstract: A fluid driven tank cleaning which includes a housing having a fluid receiving chamber, and inlet for connecting the receiving chamber to a source of fluid under pressure, and a secondary chamber separated from the receiving chamber by a common wall as a primary drive shaft rotatably mounted within the receiving chamber. A drive impeller is connected to the primary drive shaft and disposed within the inlet is provided for rotating the primary drive shaft in response to fluid entering the housing. A second drive shaft is rotatably mounted within the secondary chamber. A magnetic drive coupler is provided for magnetically coupling the primary shaft with the secondary shaft such that the secondary shaft will rotate in response to rotation of the primary shaft. A fluid nozzle assembly is rotatably mounted to the housing and is fluidly connected to the receiving chamber. A drive train is provided for rotating the fluid nozzle assembly in response to the rotation of the secondary shaft is also provided.

Abstract: A fluid device tank cleaning apparatus having a stationary housing, an outer Tee-housing which rotates about a first axis and nozzle assembly rotatably mounted to the Tee-housing for rotation about a second axis. The stationary housing is provided with passageways for communication with the Tee-housing. The passageways are configured so as to provide a substantially constant cross sectional area to the outer of the Tee-housing.

Abstract: An electrical capacitor which contains a dielectric fluid, said fluid consisting essentially of ditolylmethane.

Abstract: A process for controlling algal growth in wastewater, lagoons and ponds which comprises treating the algae containing water with a high concentration of a selected actively growing species of pseudomonas product which products an exudate which exhibits antialgal characteristics.

Abstract: A system for treating soil contaminated by petroleum hydrocarbons which comprises applying a suitable bacterial culture capable of degrading petroleum hydrocarbons in a dry form to the bottom of an excavated cavity, applying gravel to a suitable depth over said dry cultures, providing a system of distribution piping capable of supplying nutrients directly to said cultures, and also an air flow through the area containing said cultures, and placing the appropriate tank in place within said cavity and covering with gravel and dirt.The system is activated by providing said cultures with a source of nutrients through said piping followed by flowing air through the piping to facilitate metabolization of the hydrocarbons contained in the soil.

Abstract: A device suitable for seeding bacterial cultures to waste flowing through or which has accumulated in a collection system which comprises a porous outer covering member which forms an enclosed package with a source of bacterial cultures contained within said package, said cultures suitable for seeding a collection system as a waste stream flows through the porous covering member of said enclosed package causing the bacteria to be released into said waste stream.

Abstract: Monosodium phosphate is highly soluble in water and can be used as an ingredient for a low pH liquid buffer in a concentration of about 13-40 percent by weight. Tri potassium phosphate has good solubility in water and is a suitable ingredient for a high pH liquid buffer in a concentration of about 20-50 percent by weight. By a combination of these two ingredients, a system has been developed for using liquid buffer mixes in place of solid phosphate buffers, especially for use as a direct textile bath additive.
