摘要： A firearm includes a moveable bolt assembly that absorbs energy associated with the discharge of the firearm. An energy absorbing mechanism within the bolt assembly may include a dampening spring that provides recoil energy dissipation. With this arrangement, one or more actuators may be provided that are operative to compress the dampening spring with respect to the bolt assembly in response to the discharge of the firearm.

摘要： A hammer release apparatus for a hand held firearm which reduces the force required to discharge the firearm is disclosed which includes a hammer, a pivotably mounted trigger, and a restraining lever. The restraining lever engages the cocked hammer which is biased towards a firing position by a hammer spring. The restraining lever counteracts the force of the hammer spring to reduce the pull resistance associated with the trigger of the firearm.

摘要： A window assembly for transmitting light into and from a vessel containing a high pressure, high temperature, highly reactive environment includes a truncated conical window which is substantially transparent to radiation, a truncated conical metal seal which circumferentially engages the window, and a case to which the window and the seal are secured. To facilitate automatic cleaning of the window, the surface of the window which is exposed to the high-pressure environment is seated substantially flush with the high-pressure surface of the case. By initially seating the window assembly by means of mechanical pressing, then subjecting the window assembly to a series of successively higher transient combustion pressures, a window assembly can be fabricated which can withstand prolonged service in a harsh environment such as that encountered in a large caliber artillery cannon or equivalent scientific and industrial applications.

摘要： A weapon includes a barrel; a breech ring attached to a rearward end of the barrel; a groove provided in the breech ring; a movable breechblock mounted in the breech ring and having open and closed positions; a slide mounted in the breech ring and being guided by the breech ring groove for displacements relative to the breech ring; a connecting element for coupling the slide to the breechblock for causing motion of the breechblock between the open and closed positions by the displacements of the slide; and a control cam rotatably supported in the breech ring. The control cam has a cam track coupled to the slide for effecting displacements of the slide upon rotation of the control cam Further, an external drive is provided for rotating the control cam.

摘要： In order to provide a gun in which the recoil force attendant with actuation is reduced, a prototype model of a telescoping barrel gun has been designed. In this design, an inner barrel, which contains and directs the projectile, is made to slide forward within an outer barrel when the gun is actuated. The motion of the inner barrel is then stopped while the projectile moves unimpeded. The telescoping barrel design functions together with a design which requires a portion of the cartridge's propellant energy be used to produce a reduction in the force of the gun's recoil when fired. Upon firing, some of the propellant gases are channeled forward in the gun to an air space, which lies between the two concentric barrels. The forward motion of the inner barrel forces the gases in this air space from the gun through small holes located in the distal area of the outer barrel. The discharge of these gases is rearwardly directed in order to counteract the gun's recoil. After firing, the gun must be manually reloaded and the member's reassembled to their pre-actuation positions before firing again.

摘要： A short bolt rifle that enables increased barrel without an increase in weight. A longer barrel increases bullet velocity, which increases the range and accuracy of the weapon and the bullet impact energy. In this action, the bolt is simply pulled back and pushed forward. The design includes a loader mechanism that ejects spent cartridges and loads a new cartridge. This happens while the bolt is drawn back and pushed forward. A rotating lock secures the bolt in the firing position. A second version of the action uses a pistol grip. A lock holds the pistol grip, which can be released. After it is released, the user pulls down and back on the grip to open the action. The grip is pushed forward and upward, to load a shell, while the bolt is moved forward and locked. The action also can easily be adapted to fully automatic operation.
