Abstract: A suppressor for a firearm may include a core and a tube. The tube may be arranged around the core. The core may have a first longitudinal axis and include a first proximal end, a first distal, and a first end cap disposed adjacent to the first proximal end. The first end cap may include a proximal end wall and an opening for receiving a barrel of a firearm. The opening for receiving the barrel of the firearm may extend from the first proximal end to a first interior end wall. A bore may extend from the first interior end wall to the proximal end wall. The core may further include a first static vane spaced from the proximal end wall along the first longitudinal axis, and an array of baffles aligned with the bore, the array of baffles being arranged between the first static vane and the distal end.

Abstract: The present invention provides a system, method and device for locating undetonated explosive devices during the clean-up of a blasting area, the location being effected by co-locating in active or passive wireless transmitter units together with the respective explosive devices, and where the location is effected by at least one radio receiver unit that is in radio communication with the respective wireless transmitter units, where the wireless transmitter unit changes its radio frequency characteristic as a blasting operation causes destruction of the wireless transmitter unit, or in that a device in the wireless transmitter unit detects that the explosive device and the wireless transmitter unit have become separated at the blast site.

Abstract: A device is disclosed for a weapon for firing burst of several shots. The device unlocks and latches the rifle bolt in the rear position to avoid heat distribution from the chamber or barrel to the powder or explosives in the booster charge or the explosive projectile, and to prevent firing by emptying or handling the weapon. The activator moves the trigger into engagement with the stop flap of the rifle bolt, thereby releasing the spring force of the rifle bolt forwardly during firing only when the rifle bolt and the cover are in the locked position.
