The phosphorescent toy gel composition is produced by suspending phosphorescent particles in an aqueous solution, thickened with guar gum and crosslinked by a borate compound. The method for manufacturing the phosphorescent gel composition comprises, in one aspect, the steps of providing a water-based solution with a borate ion-containing compound dissolved in the water, providing guar gum and phosphorescent particles suspended and dispersed in propylene glycol, and mixing the water-based solution and the propylene glycol dispersion in a proportion to provide a phosphorescent gel composition.

Phosphorescent toy gel composition and methods of manufacture

Process for the formulation of a multi-component explosive composition from non-detonable components comprising a defined body of unconsolidated particulate aluminum fuel granules and an oxidizing liquid. Specific particulate aluminum fuel has an average particle size within the range of about 1/64-1/4 inch and is packed within a container or other confining structure to provide an average bulk density within the range of 0.2-1.0 gm/cc. The aluminum fuel particles are generally wadded-up aluminum foil granules. The oxidizing liquid added to the body of aluminum fuel fills the void space between granules of aluminum entrapping some voids within the granules to provide an average bulk density of the mixture of oxidizing liquid and particulate aluminum within the of 1.2-1.7 gm/cc, creating an explosive, formulation which is detonable in a diameter of 4 inches at 20.degree. C. by a one pound pentolite booster and normally by a 1/2 pound pentolite booster. The oxidizing liquid can comprise an aqueous solution of an oxidizing agent selected from the group consisting of alkali metal and ammonium nitrates, alkali metal and ammonium perchlorates, alkaline earth metal nitrates, alkaline earth metal perchlorates and mixtures thereof and may also include a hygroscopic freezing point depressant which may act as a sensitizer. An alternative oxidizing liquid for use with the particulate aluminum fuel comprises a nitroparaffin selected from the group of nitromethane, nitroethane, nitropropane and mixtures thereof. A specific oxidizing liquid is a nitromethane and nitroethane mixture having a nitromethane to nitroethane ratio of 0.6-1.2, more particularly, about 1.0.

Formulation of multi-component explosives

A multicomponent explosive composition and its use as a blasting agent in ditching operations and the like. The explosive comprises a fuel component and an oxidizer compnent, both of which are retained in the liquid state over wide temperature ranges and are stable over long storage intervals. The fuel component comprises a suspension of a particulate metal fuel, specifically aluminum, in a carrier liquid formed of a mixture of a water-miscible polyhydric alcohol and a pyrrolidone solvent. The carrier liquid contains a thickening agent to provide thixotropic rheological properties such that the particulate metal fuel remains in suspension at rest, but with shear forces induced by pumping, the components become more fluid for mixing and pumping easily. The oxidizer component comprises an aqueous solution of an inorganic oxidizer salt. The oxidizer solution contains void-containing materials such as glass or saran microbubbles. The void-containing materials may be suspended in the fuel component also. The fuel and oxidizer components are stored in separate reservoirs and transported to the location of the detonation site. The components are separately metered from their respective reservoirs and supplied to a static mixing zone where they are mixed together.

Multicomponent explosives

An impulse compensated continuous rod warhead including a pair of end pla; an annular or cylindrical explosive charge mounted between the end plates for providing an outward exploding impulse; a plurality of continuous rods mounted about the charge, and an annular buffer assembly disposed between the charge and the rods wherein a portion of said buffer assembly has varying mass between its ends so that the explosive impulse variation from end to end is substantially evened out before accelerating the rods.
