Abstract: A shock attenuation device is used to reduce the effect of a blast shock by both disrupting the propagation of the shock and by spreading, deflecting, and/or redirecting the shock. The device includes multiple layers of different materials, having different shock transmission impedances, stacked in a direction in which the blast shock travels through the device. At least one of the layers includes a material that crumples in response to the shock, undergoing an inelastic deformation in response to the shock. Also, at least one of the layers includes a material that has a directional shock transmission impedance that provides different shock transmission impedance within different directions within the material. The directional shock transmission material may be oriented such that the preferred direction of shock transmission within the material is oriented away from the direction of in which the multiple layers of material are stacked.

Abstract: A blasting system with automated detonator logging eliminates on-the-field manual logging of each detonator. Detonators are connected in sequence in an auto-logging circuit, and the blast machine initiates a logging operation in which each detonator receives and confirms an assigned sequence number along with assigned delay data. Elimination of manual logging by individuals increases safety in the blast zone and facilitates the blasting operation. The operation is simplified, likelihood of human error is reduced, and the cost of a separate logger device is eliminated. An auto-logging protocol may be incorporated into the control module of the electronic detonator. Alternately, an auto-logging module may be connected externally to each detonator similar to the conventional surface plus down-the-hole delay systems. The inventive system may include an IDC connector that facilitates the serial connection of the detonators for the logging circuit while allowing parallel connections of the blast control circuit.

Abstract: An efficient high-velocity compressed gas-powered gun includes a lower receiver having a trigger assembly. The efficient high-velocity compressed gas-powered gun includes an upper receiver having a gas distribution assembly and a bolt assembly configured to operate in response to actuation of the trigger assembly and configured to be operated by the gas distribution system. The bolt assembly has a first part and a second part that are separated by a small gap just prior to actuation of the trigger assembly, and become separated by a large gap, larger than the small gap, over a projectile-firing period of time immediately after the trigger assembly is actuated. The increase in the gap size is caused by movement of the second part in response to gas entering the small gap from the gas distribution assembly. The first part and the second part move together to cock the gun once they are separated by the large gap.

Abstract: A magazine loading device comprises an ammunition delivery interface, a shuttle or escapement, an orientation gate, a staging gate, a plunger, and a magazine receiver. The ammunition may be supplied to the ammunition delivery interface in a number of ways, including utilization of a hopper. The ammunition may be guided into an opening in the shuttle or escapement, which may then transfer the ammunition to an orientation gate. The geometry of the orientation gate is such that the ammunition will always drop through the orientation gate with the projectile down, which in this case is the desired orientation for loading into the magazine. A plunger may then push the ammunition into the magazine.
