3 Method and a device for cast-loading explosive charges US339589 1982-01-15 US4421004A 1983-12-20 Stig Hallstrom; Lars Horman
The present invention relates to cast-loading of explosive charge compositions comprising at least two explosive components for cast-loading of a plurality of moulds or shell bodies (6) in a closed transportable unit (1). The moulds or shell bodies (6) are preheated to a predetermined temperature essentially corresponding to the melting temperature of the explosive charge composition. With the predetermined temperature substantially maintained the moulds or shell bodies (6) are filled with the liquid explosive charge composition after which a vibration movement of a specific frequency is imparted on the filled moulds or shell bodies by means of ball vibrators (24). Heavy particles of the explosive charge composition sink to the lower parts of the moulds or shell bodies. After a predetermined time period for sedimentation the filled and vibrated moulds or shell bodies are then cooled to a low temperature for solidification of the charges.
4 Cartridge ammunition US09903519 2001-07-13 US20010047736A1 2001-12-06 Stefan Thiesen
A cartridge ammunition includes a cartridge case having a front and a rear; a projectile inserted into the cartridge case at its front and extending into the cartridge case; an igniter provided in the rear of the cartridge case; and a propellant charge accommodated in the cartridge case. The propellant charge is formed of a compacted bulk propellant powder having a density of between 0.9 and 1.2 g/cm3.
