The insert is inserted into and positioned within bores of the first barrel portion and the second barrel portion. The first barrel portion and the second barrel portion include corresponding connection mechanisms that allow the first barrel portion and the second barrel portion to removably couple with one another. The insert includes a ridge that is fixed positioned between the first barrel portion and the second barrel portion when the first barrel portion and the second barrel portion are coupled. The first barrel portion and the second barrel portions can receive inserts with different bore sizes (e.g., inner diameter).
Abstract: In one embodiment, an apparatus includes a collapsible workstation assembly to be used in a temporarily-mounted control system of an aircraft. The collapsible workstation assembly is mounted to a floor of the aircraft via one or more mounting plates and one or more adaptive floor plates. The collapsible workstation assembly includes a number of modules for display and user controls. Each of the modules are connected via hinges and hinge locks to be moved between a deployed position for use and a stowed position when not in use. The collapsible workstation assembly is further connected to an observer chair assembly and a temporary door plug.

Abstract: Systems, methods, and devices are provided for providing flight response to flight-restricted regions. The location of an unmanned aerial vehicle (UAV) may be assessed and used to calculate a distance between the UAV and a flight-restricted region. Different flight-response measures may be taken based on the distance between the UAV and the flight-restricted region.
Abstract: A .22 caliber rimfire cartridge includes a generally cylindrical casing having a rearward rimfire end and an opposing mouth end, wherein the rearward rimfire end has an annular rim connecting to a cylindrical casing portion extending to a casing forward edge and a bullet is disposed in the forward mouth end. In embodiments, the bullet comprises copper and a polymer binder. In embodiments, the bullet has a forward tapering portion with a central cavity, a first cylindrical portion with a first diameter and a cylindrical surface directly rearward of the tapering portion, a cylindrical driving band directly rearward of the first cylindrical portion, the cylindrical driving band having a second diameter greater than the first diameter and having an outer second cylindrical surface, a third cylindrical portion directly rearward of the cylindrical driving band, the third cylindrical portion having a third cylindrical surface with a diameter equal to the first diameter.
Abstract: The present disclosure provides rolling release launching system that is operative to receive and retain a drone or other payload in a protected launcher. The launcher helps to reduce the drag of the payload and to protect the payload from environmental factors. The payload is launched when a rotating door opens to expose the payload in a bay area. The rotating door may be parallel or concentric to a longitudinal axis of the body portion of the device. The payload may be launched using a biasing and fastening mechanism, which may include detachably coupling bracket, to induce an angular moment and releasing force on the payload during launch.

Abstract: This disclosure provides a stackable propellant module for use inside of a gas generation canister. The modules are designed to enable them to be individually fired rather than as a unitary mass, as done in conventional configurations. This enables the generation of a controlled pressure profile rather than an uncontrolled pressure profile determined by the environmental conditions downhole, such as temperature and pressure.
Abstract: For an externally powered weapon, in particular a machine weapon and a machine gun, having at least one barrel, a recoil intensifier at the front end of the barrel is proposed to intensify a weapon return of the returning masses of the weapon and to generate and intensify a signal for monitoring, in particular functionally monitoring, the weapon. The recoil intensifier is of a flared form. The signal intensified by the intensification is used for example for counting the number of shots fired, initiating an emergency stop function, etc. Depending on the further use, the mechanically intensified signal may be converted into an electrical signal.
