  • Patent number: 10670366
    Abstract: A dual and omnidirectional mortar base plate to be used in mortar carrier vehicles comprising a bottom base plate coupled to a mortar and a top base plate; wherein the dual base plate is adapted to move along a movement path from a resting position, associated with a position for movement of the vehicle, towards a work position associated with a firing position for the mortar, and vice versa. Likewise the dual base plate has elements for fast stowage in the mortar carrier vehicle. The dual base plate consists of a bottom base plate, a top base plate, and connection and repositioning elements between the two to facilitate the transfer of the forces generated by said firing to the ground, isolating the mortar carrier vehicle from the forces generated by firing the mortar. Truncated cone shaped hoppers allow the bottom plate to move in any direction in which the mortar is fired.

  • Patent number: 9862505
    Abstract: A technique is directed to launching an unmanned aerial vehicle (UAV). The technique involves positioning a UAV launcher over a ground location. The technique further involves installing, after the UAV launcher is positioned over the ground location and prior to launching the UAV, an anchor into the ground location to anchor the UAV launcher to the ground location. The technique further involves operating, after the UAV launcher is anchored to the ground location, the UAV launcher to impart launching force onto the UAV to launch the UAV, the anchor holding the UAV launcher substantially in place at the ground location to minimize energy loss as the UAV launcher imparts launching force onto the UAV. In some arrangements, the UAV launcher is capable of pivoting while remaining anchored between launches to accommodate changes in wind direction while maintaining substantial connection to the ground location for enhanced consistency and performance.

    Abstract: A gun whose barrel (2′) is connected to a breech ring (16), and is seated to be displaced in a cradle barrel (3). To prevent a lifting effect of the barrel (2′) inside the cradle barrel (3) upon firing, a slide-bushing bearing is disposed on at least the muzzle side of the barrel (2′).

The radial sliding guidance of the barrel (2′) during firing is effected by tab-shaped protrusions (10′), which extend into corresponding, groove-shaped recesses (9′) of the barrel bushing (7′) and hold the barrel (2′) in the center of the barrel bushing (7′).

    Abstract: A detachable mount for a telescopic sight which can be operated using only one latching mechanism. The mount uses a front base attached to the ring of a rifle receiver and a rear base attached to the bridge of a rifle receiver. The upper surfaces of both the front and rear bases open into a pair of slots. A separate scope mount is attached to a scope sight by conventional means. Two sets of lugs descend from the lower surfaces of this scope mount. These sets of descending lugs are configured to fit securely within the slots in the front and rear bases when the scope mount is placed over the bases. The forward facing surfaces of the rear set of descending lugs mate with a corresponding set of rearward facing surfaces in the slots within the rear base. These sets of mating surfaces are offset from the vertical to create a wedging effect that pulls the rear of the scope mount down when it is pushed forward relative to the rifle receiver.
