Abstract: Aqueous carbonaceous slurries having reduced viscosity, a stabilized network of carbonaceous material in water and improved pumpability are obtained by having present a salt of naphthalenesulfonic acid formaldehyde condensate and at least one water soluble polymer selected from the group consisting of sodium alginate, guar gum, locust bean gum, carboxymethylhydroxypropyl guar gum, hydroxypropyl guar gum and guarpak guar gum. For example, a mixture of 96.8% by weight of ammonium naphthalenesulfonic acid formaldehyde condensate and 3.2% by weight of sodium alginate can be added to an aqueous coal slurry in an amount of 0.31% by weight of the slurry.
Abstract: Flatting agents, such as silica, talc and carbonates are present in radiation hardenable compositions in order to reduce gloss and obtain a flat appearance in cured coating. However, the flatting agent settles in the radiation-hardenable composition. To reduce settling of the flatting agent, one or more stabilizers are added to the composition. Useful stabilizers are alkylene oxide adducts of particular siloxane copolymers.
Abstract: Aqueous carbonaceous slurries having reduced viscosity, a stabilized network of coal in water and improved pumpability are obtained by having present a salt of naphthalenesulfonic acid formaldehyde condensate and at least one water soluble polymer selected from the group consisting of gum karaya, mixtures of gum karaya and polyacrylamide and polysaccaride modified with polyacrylate. For example, a mixture of 61.5% by weight of ammonium naphthalenesulfonic acid formaldehyde condensate and 38.5% by weight of gum karaya can be added to an aqueous coal slurry in an amount of 0.13% by weight of the slurry.
Abstract: Additives for cementitious materials are formed from mixtures of (1) salts of naphthalene or lower alkyl substituted naphthalene sulfonic acid formaldehyde condensates and (2) water-soluble resins selected from the group consisting of resorcinol- formaldehyde and catechol-formaldehyde resins. Addition of these mixtures to cementitious materials results in improved slump and compressive strength.
Abstract: Increased antibiotic content of oxytetracycline injectable compositions containing glycerol formal as the solvent is achieved by utilization of particular magnesium compounds, viz., magnesium oxide, magnesium hydroxide, magnesium carbonate, magnesium acetate and magnesium chloride. Magnesium chloride is utilized with oxytetracycline base only.
Abstract: Superplasticizers with improved water reducing properties for cement, cement slurries, mortar, grout and concrete are formed from synergistic mixtures of (1) aromatic sulfonic acid formaldehyde condensates, such as the sodium salt of naphthalene sulfonic acid formaldehyde condensate and (2) hydroxy aromatic compounds such as pyrogallol and gallic acid. Addition of these mixtures to the same cementitious materials also results in improved compressive strength.

Abstract: Extremely rapid ambient curing of polyepoxide resins and mixtures of polyepoxide resins and polyacrylate esters is achieved by use of a curing system composed of at least one polymercaptan and at least one catalytic co-curing agent which is the condensation product of:(a) aliphatic amine or substituted aliphatic amine containing at least one primary aliphatic amine group where the aliphatic moiety is ethylene or greater with(b) at least one amino acid, its corresponding lactam or other amide forming derivative.Optionally, known Lewis Base catalysts for the epoxy/mercaptan reaction, such as tertiary amines, may also be used.

Abstract: Radiation curable diluents have been developed which are acrylic acid esters of alkoxylated 1,6-hexanediol, neopentyl glycol and tripropylene glycol, each having a relatively low degree of alkoxylation. Examples are diacrylates of adducts of neopentyl glycol with two moles, four moles and six moles, respectively, of ethylene oxide and with two moles and four moles, respectively, of propylene oxide.

Abstract: Pressure sensitive recording sheets are prepared characterized by containing on one side thereof color former dissolved in a solvent which is one or a mixture of alkoxy diphenyl alkanes having the following structure: ##STR1## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or a straight or branched chain alkyl group of 1 to 8 carbon atoms and can be the same or different; R.sub.5 is a straight or branched chain alkyl group of 1 to 9 carbon atoms; R.sub.6 is a straight or branched chain alkyl group of 1 to 8 carbon atoms; x is 0, 1 or 2; y is 1 or 2 and n is 1 or 2, with the proviso that the sum of the carbon atoms in R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 does not exceed 9 and with the further proviso that where the alkoxy diphenyl alkane is a solid to viscous liquid, at least one diluent or at least one other generally liquid solvent or mixture thereof is present. The treated side of the sheet is brought into contact with a developer.
Abstract: Trace minerals when in contact with vitamin A in animal feed supplements and in animal feed have a deleterious effect upon vitamin A. This effect is reduced by treating trace minerals with lignin sulfonates before bringing the trace minerals into contact with vitamin A.
Abstract: Microemulsion defoamer compositions which are oil in water colloidal dispersions are useful in defoaming aqueous systems such as in paper machines and latex paints. These compositions are prepared by mixing a water dispersible organic material, ethylene oxide condensate, coupling agent, water, basic material and antigelling agent.
Abstract: 6-Hydroxyhexyl perfluoroisopropyl ether is prepared by reaction of hexafluoroacetone and potassium fluoride to obtain an alcoholate which is then reacted with 1-chloro-6-hexanol. One mole of the ether may be reacted with about 1 mole to about 20 moles of ethylene oxide to produce a hydroxyethyl ether. One mole of 2,2,3,4,4,4-hexafluorobutanol may be reacted with from about 1 to about 5 moles of propylene oxide to produce a hydroxypropyl ether. One mole of hexafluorobutanol may also be reacted with about 1 to about 5 moles of propylene oxide and then about 1 mole to about 20 moles of ethylene oxide to produce a hydroxyethyl ether. The hydroxyhexyl ether, hydroxylpropyl ether and both hydroxyethyl ethers may be sulfated to produce anionic surfactants which are useful as antistatic agents and lubricants for polymeric shapes such as nylon films and filaments.
