  • Patent number: 8066833
    Abstract: A novel non-toxic IR tracer composition is provided herein which, when incorporated into an IR tracer projectile which is then fired, generates a dim visibility IR trace. Such IR tracer composition is a non-toxic, boron-containing, IR tracer composition comprising: from about 20 to about 30% by weight, or from about 45 to about 60% by weight, of potassium perchlorate; from about 5 to about 16% by weight of a metallic fuel which consists of boron; from about 20 to about 25% by weight, or from about 40 to about 50% by weight, of a non-metallic fuel which consists of sodium salicylate; from about 5 to about 10% by weight of a retardant which consists either of iron carbonate or magnesium carbonate; and an effective amount of binder, wherein the total percentage of such ingredients add up to 100%. A novel IR tracer projectile containing such IR tracer composition for generating a dim visibility IR trace is also provided.

  • Patent number: 7985311
    Abstract: Novel non-toxic, heavy-metal free, zinc peroxide-containing, IR tracer compositions are provided herein, which, when incorporated into a medium caliber IR tracer projectile and fired, produce a dim visibility IR trace. Such IR tracer compositions comprise from about 65 to about 75% by weight, of zinc peroxide; from about 15 to about 25% by weight of a fuel which consists of sodium salicylate; and an effective amount of a binder which is selected from the group consisting of calcium resinate and cellulose acetate butyrate. The total percentage of the ingredients adds up to 100%. Medium caliber, i.e., 0.50 caliber, IR tracer projectiles containing such IR tracer compositions are also provided.

  • Publication number: 20100300319
    Abstract: A primer composition with reduced toxicity suited for reduced-energy ammunition comprises bismuth (III) oxide as the principal oxidizer and contains a portion of propellant composition mixed therein. This composition may also be used in a cartridge which is otherwise substantially free of any other propellant compound and preferably produces a residue which is substantially free of toxic substances.

  • Publication number: 20080257194
    Abstract: A novel non-toxic IR tracer composition is provided herein which, when incorporated into an IR tracer projectile which is then fired, generates a dim visibility IR trace. Such IR tracer composition is a non-toxic, metallic-boron-containing, IR tracer composition comprising: from about 20 to about 30% by weight, or from about 45 to about 60% by weight, of potassium perchlorate; from about 5 to about 16% by weight of a metallic fuel which consists of metallic boron; from about 20 to about 25% by weight, or from about 40 to about 50% by weight, of a non-metallic fuel which consists of sodium salicylate; from about 5 to about 10% by weight of a retardant which consists either of iron carbonate or magnesium carbonate; and an effective amount of binder, wherein the total percentage of such ingredients add up to 100%. A novel IR tracer projectile containing such IR tracer composition for generating a dim visibility IR trace is also provided.

  • Publication number: 20060231179
    Abstract: A novel non-toxic IR tracer composition is provided herein which, when incorporated into an IR tracer projectile which is then fired, generates a dim visibility IR trace. Such IR tracer composition is a non-toxic, metallic-boron-containing, IR tracer composition comprising: from about 20 to about 30% by weight, or from about 45 to about 60% by weight, of at least one of potassium chlorate or sodium nitrate; from about 5 to about 16% by weight of a metallic fuel which consists of metallic boron; optionally, from about 15 to about 25% by weight, or from about 40 to about 50% by weight, of a non-metallic fuel which consists of sodium salicylate; from about 5 to about 20% by weight of a retardant which consists either of iron carbonate, or magnesium carbonate or calcium carbonate; from about 5 to about 15% by weight of a first binder which consists of calcium resinate; and up to about 7.
