Abstract: This invention constitutes improvement in the art of introducing fuel additives into the fireside of coal fired boiler tubes to facilitate the removal of slag and like deposits from the fireside, to lower acid smut pollution, to control corrosion, and to improve the electrical resistivity of particulate emission. The improvement is achieved by the addition of pulverized coal to the fuel additives.

Abstract: The invention disclosed is directed to liquid detergent-germicide compositions which include an antimicrobial active phenolic derivative in combination with hydroxyacetic acid and a detergent. The present compositions are found to have significant antimicrobial activity in water, even with low concentrations of the phenolic derivative, a low skin irritation factor, and good color stability without any substantial degree of darkening under conditions of light and heat which typically convert phenolic containing disinfectants to a dark color.

Abstract: A continuous mixing device for preparing emulsions comprising a chamber with a means of providing high shear mixing, e.g., a plurality of mixing blades on a shaft in the axis of the chamber, and with a plurality of entrance nozzles, e.g., at the bottom of the chamber and one or more in the sides thereof, for sequential addition of liquids at a controlled rate.

Abstract: The invention disclosed provides a new improved slurry detergent and to a method of using same. The slurry detergent may be formulated with alkali metal hydroxides and/or silicates, condensed phosphates, sodium hypochlorite and sodium polyacrylate, or the like. The new improved slurry is found to have significant advantages over both liquid detergents and powder detergents in dispensing as well as in use.

Abstract: The invention disclosed provides a new composition and method for inhibiting corrosion. The present composition is relatively non-toxic, contains no chromates and zinc, and consists essentially of an azole and a water-soluble phosphate in an effective combination. Effective amounts of the corrosion inhibiting composition are used to provide corrosion protection in both ferrous and non-ferrous metals.

Abstract: Lignin carboxylic acid is added to raw cement mix slurry prior to wet-grinding, whereby the amount of water required is reduced.

Abstract: Control of microorganisms in industrial recirculating water systems using polyquaternary amines.

Abstract: The invention disclosed provides a new composition and method for inhibiting corrosion. The present composition is relatively non-toxic, contains no chromates, and consists essentially of an azole, water-soluble phosphate and water-soluble organophosphonic acid. Effective amounts of the corrosion inhibiting composition are used to provide corrosion protection in both ferrous and non-ferrous metals.

Abstract: Low toxicity, low pollution potential compositions and methods for inhibiting corrosion of ferrous and non-ferrous metallic parts in aqueous systems. The compositions have no chromate, no polyphosphate and no borate and consist essentially of alkali metal nitrite, alkali metal carbonate or bicarbonate and an azole. Preferably the compositions also include an alkali metal silicate and small amounts of an alkali metal hydroxide. In the corrosion inhibiting method, the aforesaid compositions are added to the system water in amounts sufficient to provide from about 100 to 10,000 parts per million ("ppm") of alkali metal nitrite, the primary inhibitor.

Abstract: This invention provides an improved composition and method for dispersing high molecular weight flocculant polymers and copolymers used for water and waste treatment by the combination of the polymer with an inert additive and a small amount of water.

Abstract: Oil-in-water or water-in-oil emulsions can be demulsified with cationic starches of the quaternary ammonium type.

Abstract: An analytical cell assembly comprising a base with a radiation source mounted on one end, an enclosure on the other end, and a cell proper, with cell heating means, within the enclosure. The enclosure and cell have cooperative fluid flow connections whereby the cell is modular and may be simply lifted out of the enclosure. The enclosure also includes a collimating lens assembly interposed between the cell within the enclosure and the source outside the enclosure on the base. The entire assemblage of source, enclosure and cell can be moved as a unit, making it modular, or just the cell can be moved as a module leaving the enclosure and the source in place in an instrument using the invention cell assembly.

Abstract: This invention provides an improved composition and method for dispersing high molecular weight flocculant polymers and copolymers used for water and waste treatment by means of an effervescing additive.

Abstract: Clarification of iron waste waters using basic dyes such as methylene blue, methyl violet or malachite green and the like, alone or in combination with organic or inorganic additives.

Abstract: A combined timer, blow down warning device, chemical pump, and controller for boilers. The circuit comprises an electro-mechanical array of relays, flashing lights and alarms and an electronic tripper which operates from the rate of change in temperature in the blow down tailpipe, to turn off the lights and alarms only after a manual blow down operation has been performed.

Abstract: The invention disclosed provides a method for boiler water treatment to retard corrosion due to dissolved oxygen. Hydroxylamine, certain derivatives thereof and their salts have now been found to be highly effective oxygen scavengers for use in boiler water and thereby effect reduction of corrosion resulting from dissolved oxygen.

Abstract: Corrosion inhibiting compositions containing hydroxyamine phosphate ester or water-soluble derivative thereof, together with water-soluble zinc salt and 1,2,3-triazole or water-soluble derivative thereof; and methods for inhibiting corrosion in aqueous systems therewith.

Abstract: The invention disclosed relates to new improved corrosion inhibitors for cooling water systems, preparation thereof and use to inhibit metal corrosion in aqueous systems. The present corrosion inhibitors are 1,3,5-triazine-4,6-diketo 2-dithio ammonium phosphamate and 1,3,5-triazine 4,6-dithio 2-dithio ammonium phosphamate.

Abstract: The invention disclosed relates to a method for using a new improved composition for inhibiting or preventing accumulation of scale or the like on heating surfaces in an aqueous system. The present composition includes (A) copolymers of styrene sulfonic acid with acrylic or methacrylic acid, and their water-soluble salts; or (B) mixture of polystyrene sulfonic acid with polyacrylic or polymethacrylic acid, and their water-soluble salts.
