  • Patent number: 12276488
    Abstract: A multi-compartment mortar increment container (MIC) enables burning of two propellants to broaden the pressure-time curve providing additional energy and force behind a mortar shell while maintaining allowable pressures. During the ballistic cycle, the mortar increment container burns allowing the faster propellant to mix with the slower propellant. The slower propellant will burn later in the ballistic cycle generating higher pressure behind the projectile leading to higher velocity.

  • Patent number: 8696838
    Abstract: A method of manufacture of foamed celluloid molded products, involving three steps for the manufacture of higher density (0.7 to 1.25 gm/cc) foamed celluloid products or simple geometry lower density (0.2 to 0.7 gm/cc) foamed celluloid products, and four steps for the manufacture of lower density foamed celluloid products of any geometry. The three step process involving: (1) providing small, uniform, pieces of celluloid; (2) presoaking the pieces in a physical blowing agent (PBA) under pressure; and (3) foaming at raised temperature a controlled quantity of the presoaked pieces in a mold—to obtain the desired shape and density. For a lower density foamed celluloid product, of any moldable geometry, the steps are to: (1) small pieces of celluloid, that (2) have been presoaked in a PBA, are (3) pre-expanded to an intermediate density, and then (4) foam the desired lower density foamed product in a mold at raised temperature.

  • Patent number: 8597444
    Abstract: By using generally known chemically, physically, or a combination thereof, means to foam celluloid, a foamed celluloid material is invented with a density of less than about 1.25 gm/cm3, which material is relatively low cost, very fast burning, very low residue, easily moldable, and which material exhibits good mechanical strength, and provides a good water barrier. These characteristics make this foamed celluloid a preferred choice for military artillery propellant charge bags, military mortar and civilian fireworks increment charges, combustible cartridges, flare housings, igniter tubes, as well as, closure disks, combustible enclosures and components thereof, among other applications.

  • Publication number: 20050217572
    Abstract: Particle coating processes and systems employ UV curable materials to form tack-free surfaces rapidly. By applying UV curable compositions on well suspended particles a UV particle coating technology enables a scalable process of coating fine particles at desirable coating thicknesses with a wide spectrum of obtainable properties. Processes in accordance with the present invention decouple the particle suspension and film formation steps, enabling ample time to first deliver evenly the coating materials to the particle surfaces, followed by rapid polymerization/curing reaction induced by the UV light to rapidly create tack-free surfaces, thus preventing particles agglomeration while achieving uniform and thin-layer coating.
