Abstract: The invention relates to a wedging arrangement to plug a blast hole accommodating an explosive charge. The wedging arrangement comprises a body comprising a first part and a second part arranged to angularly slide relative to each other. Each of the first and second parts defines a holding arrangement for holding the first and second parts relative to each other. The wedging arrangement is configurable between a default configuration in which the holding arrangement holds the first and second parts relative to each other, and a stressed configuration in which the body is subjected to external stress forces thereby causing the holding arrangement to be disengaged to allow the first and second parts to angularly slide relative to each other, in use to locate and lock the wedging arrangement in place within the blast hole in order to plug the blast hole and contain the blast energy resulting from the explosive charge being detonated.

Abstract: The biometric firearm chamber lock is a biometric electro-mechanical locking system integrated firearm safety device. The device safely locks firearms by securing the firearm lock into the firearm chamber through the ejection port to prevent rounds from being fired. An electrical biometric sensor quickly unlocks the firearm lock from the firearm. A mechanical backup unlock mechanism is used if a replacement battery is unavailable or if the electrical components fail and cannot be used to unlock the firearm lock. The firearm lock is an independent structure requiring no installation process.

Abstract: Improvements in a projectile launcher with a two-part bolt is disclosed. The two-part bolt has a forward bolt that moves and locates the projectile from the magazine to the breach. The ball is maintained in the breach until pressurized air pushes the projective out of the launcher. A ball holder is biased by a spring and when the bolt is moved, the bolt will lift the ball holder and blocks loading of a second projectile. An adjustable barrel detent alters pressure on top of the projectile to create backspin. The two bolt parts forms a piston to drive the projectile forward. A spring between the forward bolt and the rear bolt to maintains an extended biased location between the two bolt components. Travel between the two bolt elements if maintained by a pin that is retained in the rear bolt with a pin keeper spring.

Abstract: An explosive booster for initiating, and thus causing detonation of, a bulk explosive, includes a hollow body comprising a base member and a sidewall projecting from the base member. The body defines an interior space between the base member and the sidewall for containing a detonable booster formulation in use. A hollow elongate initiator locating formation projects longitudinally into the interior space at least from the base member and defines an initiator channel that is open through the base member, for locating an explosive initiator in initiating proximity relative to a detonable booster formulation contained in the interior space in use. The initiator channel extends longitudinally along a central longitudinal axis thereof that is radially spaced from, and parallel to, a central longitudinal axis along which the interior space longitudinally extends.

Abstract: Disclosed is an extractor for an autoloading firearm, the extractor having an extractor body extending a proximal end portion to a distal end portion. A knuckle is between the proximal end portion and the distal end portion and defines a pin opening extending crosswise through the extractor, where the pin opening has an elongated shape. During rearward movement of the bolt after firing, the elongated opening enables the extractor to shift downward and/or forward so that part of the extractor contacts the bolt, thereby preventing the extractor from pivoting about the extractor pin.
