Latest Patents

Frey's latest patents include an incendiary fragmentation particle and a device for the rapid generation of smoke screens. The incendiary fragmentation particle consists of a metal carrier body with ribs and a polymer incendiary mass containing a pyrophoric metal formed around the carrier body. The carrier body may be made from steel wire, which is coated with a curing agent of a two-component epoxy resin. This is then joined with the incendiary mass of pyrophoric metal and epoxy resin under raised temperature and high pressure. These fragmentation particles can be embedded in a matrix of epoxy resin for use in active components of ammunition bodies.

The second patent focuses on a device for generating smoke screens for both civilian and military applications. It utilizes briquetted, combustible masses that are spread in a buckshot-like manner through scattering charges. The invention features nontoxic, hygroscopic smoke charges fully encapsulated in a moisture-impervious ignition layer. This design allows for the laying of smoke screens over large target areas using ammunition bodies that comprise smoke charges of varying sizes and geometries.
