Patent number: H925Abstract: An encapsulated signal illuminant flare composition is comprised of powde magnesium from about 45 to about 60 weight percent, of powdered sodium nitrate from about 32 to about 49 weight percent, and of capsular adhesives containing about 91 weight liquid materials contained within capsules having cell walls of equal parts Arabic gum and gelatin of about 9 weight percent to yield a binder from about 6 to about 12 weight percent. The composition ingredients are blended in a dry mixer to achieve a homogeneously, blended signal illuminant flare composition. The blended signal illuminant flare composition is incrementally fed into a flare press for compacting into cartridges in two increments at about 14,000 psi pressure which ruptures the capsular adhesives by hydraulic forces to achieve polymer mixing and the surrounding of the powder ingredients with the binder ingredients to form a very homogenous signal illuminant flare composition mass.Type: GrantFiled: November 22, 1989Date of Patent: June 4, 1991Assignee: The United States of America as represented by the Secretary of the ArmyInventor: David C. Sayles
