Abstract: The present invention is directed to a continuous process for producing a foamable celluloid product by introducing a solid component (comprising nitrocellulose, chemical blowing agent (CBA), stabilizer and alcohol) and a liquid component (comprising camphor and acetone) into a mixer/devolatilizer machine where the chamber is under atmospheric pressure and having significant overhead space. The chamber is comprised of two zones wherein the first zone has a temperature that is less than the second zone and at least one rotor comprising hollow, temperature-controlled arms having a tilted angle affixed to the rotors. The rotors of the mixer/devolatilizer machine act to mix the solid and liquid components under lower shearing forces, lower mechanical stress and longer residence times than those used by twin-screw extruders.

Abstract: A safety fuze for use in military and commercial applications, includes a fuze body that is attached to a trigger mechanism, an energetic train contained within the fuze body, and a non-energetic fuze delay mixture that is formed in a rod form so that it can dropped inside the fuze body, without modification to the other components of the safety fuze. Preferably, the non-energetic fuze delay mixture is made of foamed celluloid.

Abstract: A modular artillery charge system module includes a central igniter container and cap end and body end igniter containers fixed to the central igniter container. The central igniter container is a rigid, longitudinal tube with opposing ends. The end igniter containers are fixed to the opposing ends of the central igniter container. Each end igniter container includes a large container portion and a small container portion that extends from the large container portion toward the central igniter container. The central igniter container and end igniter containers are made of a rigid material, such as foamed celluloid.
