Abstract: Propellant charge component for use with a projectile (4) for muzzle-loaded weapons. The propellant charge component (5) and the projectile (4) are each capable of being loaded into the weapon separately. The propellant charge component (5) is provided with a piston (14) which is capable under the effect of gases from the propellant charge component (5) of being separated from the propellant charge component (5) in the direction of firing of the projectile until it comes up against a stop organ (17) arranged on the propellant charge component (5), whereby the impact against the stop will impart kinetic energy to the propellant charge component (5) causing it to be ejected from the weapon.

Abstract: A crash detector is provided for controlling actuation of an actuator such as a release mechanism for seat belts, an air bag or the like. A main body such as a ball is located in a bore in a housing and retained by a first, relatively weak spring. A firing pin having a portion for actuating the actuator is axially movable in the housing bore. A second spring biases the firing pin towards an inoperative position. The firing pin is moved to an actuating position when the deceleration force acting on the vehicle, and hence the mass body, exceeds a predetermined magnitude.
