A pyrophoric powder made of an alloy of misch metal having a particle size distribution making it particularly suitable for employment in an airborne incendiary device in combination with an organic binder that serves to initiate oxidation and as an oxidizer. Incendiary devices using the powder dispersion exhibit prompt and sure ignition followed by the formation of a clinker with uniform and slow secondary burning properties.

Improved hydrocarbon fuel compositions suitable for employment in internal combustion engines, e.g., spark-ignition engines, compression-ignition engines, and turbine engines, and the operation of said internal combustion engines therewith. The hydrocarbon fuel compositions of the instant invention comprise a major proportion of a hydrocarbon fuel, especially one boiling in the gasoline boiling range, and a minor proportion of an additive which imparts to the hydrocarbon fuel composition deterge...

Asphaltic compositions are prepared having suitable softening points, needle penetration and stain values for use in paper laminates. These compositions are prepared by airblowing a blend of a major amount of asphalt and a minor amount of foots oil derived from slack wax from a medium lubricating oil distillate.

The coating composition of this invention consists essentially of a dispersion of aluminum powder and zinc oxide in an aqueous solution of soluble alkali metal silicate containing dissolved chromate. The relative proportions of the ingredients in the preferred compositions are in the range of from about 100 to 500 grams aluminum powder and 30 to 100 grams zinc oxide per liter aqueous solution containing from about 200 to 1200 grams alkali metal silicate and from about 1 to 5 grams chromate. Afte...

An hydraulic composition for setting or hardening soils comprising 100 parts by weight of a component A and 6 to 10 parts by weight of a component B. Component A is the product obtained by calcining a mixture of the following constituents: 100 parts by weight of limestone; 3 to 6 parts by weight of alumina; 15 to 30 parts by weight of silica; 4 to 10 parts by weight of magnesium oxide; 5 to 10 parts by weight of iron oxides; and 5 to 10 parts by weight of magnesium chloride. This mixture is pref...

A polyamide yarn-lubricating composition of particular value to yarns that are to be subjected to a false-twisting operation which comprises in dispersion a volatile aliphatic ester (A), optionally a volatile oil-soluble surfactant (B), an anionic surfactant (C), that is different from (B) if (B) is present and an antistatic agent (D).

Bleaching compositions, substantially free from "pinholing" textiles are prepared by mixing calcium hypochlorite, sodium tripolyphosphate and diluent salts in particulate form and in specified ratios, compacting to form aggregates, disintegrating the aggregates to form homogeneous granules and sizing the granules.

Disclosed herein are compositions of matter having valuable combustion properties. The compositions are particularly desirable in combinations having enhanced ignition and continued combustion properties in forms based on natural source and manmade (reconstituted) firewood and briquettes for heating, cooking and the like. The compositions involved contain mixtures of straight chain and branched chain olefins and paraffins of selected molecular weight with preference for the co-presence of higher...

A resistor composition in the form of an oxide containing niobium and ruthenium in which the atomic ratio of metal to oxygen is 1:2 and in which the atomic ratio of niobium to ruthenium is within the range of 1:2000 to 1:1.

In a method for preparing dry stable bleaching and oxidizing compositions containing at least one peroxygen compound and at least one organic acid anhydride, the improvement which comprises: absorbing the organic acid anhydride on a particulate inert absorbent material, providing said absorbed material in a predetermined granulated size range, and mixing said granulated product with at least one peroxygen compound to prepare a novel solid bleaching and oxidizing composition which is stable over ...
