Abstract: A launch assist system for supplementing the launch acceleration forces of a projectile, rocket or missile. An airtight chamber covered by a flexible elastic membrane supports a platform in the center of the membrane; the platform is electromagnetically coupled to a cocking mechanism that withdraws the platform into the chamber. Air within the chamber is removed and compressed to be stored in a holding tank as the platform is lowered into the chamber and as the flexible elastic membrane extends into the chamber. The electromagnetic coupling may be triggered to release the platform to permit the stored energy in the extended flexible elastic membrane, and in supplemental force members, to apply acceleration forces to a launch vehicle; the compressed air stored in the tank is simultaneously released to fill the chamber as the flexible elastic membrane is withdrawn.
Abstract: A safety locking device for engaging the trigger guard assembly of a firearm. A preferred embodiment includes a housing having a slot formed therein and configured to receive the trigger and trigger guard portion of a firearm, and a locking mechanism to prevent removal of the firearm from the device. The locking mechanism further comprises a locking assembly operably attached to a locking rod which can be moved into or out of a channel containing a ball that when held in place by the rod causes the slot that contains the trigger guard to narrow sufficiently to prevent the removal of the trigger guard and thus the firearm. The lock may comprise a conventional key-operated lock or an electronic lock. The locking device is designed primarily to be incorporated into a holster.
Abstract: Cartridges (5) are guided during a loading phase shortly before reaching the automatic cannon (1) onto a first track, which differs from the conveying direction of the conveyor chain (14) and are guided at a greater distance from the revolving drum (13) around the shaft (15) of the revolving drum, and conveyed on. In a firing phase, the cartridges (5) are guided shortly before reaching the automatic cannon (1) onto a second track, which differs from the conveying direction of the conveyor chain (14), are guided around the shaft (15) of the revolving drum (13), and are sequentially brought into a firing position directly behind the revolving drum. After having been fired and ejected, the empty cartridge cases (6) are caught and are transported on the first track into a magazine (4).
Abstract: 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.
Abstract: According to the present invention, a firing mechanism adapted to discharge a non-impact fired ammunition cartridge in a revolver comprises a trigger, a hammer, a stirrup, a transfer bar, a link, and a rebound. The trigger is hung conventionally on a frame of the revolver and adapted for rotation to and from a firing position. The transfer bar is engaged with the trigger and configured for movement into and out of engagement with a firing probe during actuation of the firing mechanism. The hammer is coupled to the stirrup via the link such that the hammer and stirrup rotate in opposite directions. The rebound has a front end coupled to the trigger and a rear end which receives a main spring. The main spring is captured between the stirrup and the rebound to bias the trigger toward recovery and the stirrup and hammer toward their respective firing positions.
Abstract: A device for automatically putting revolvers on safety is provided. The device includes a trigger (16) in a mounting position and a percussion or firing position for the control of the hammer. The hammer is stressed by a release spring (15). A spring-loaded (22) safety piston (20) is arranged between the hammer (14) and the stock (11) of the gun, and is intended for spacing the hammer with the firing pin in the case of a percussion, automatically placing it in a neutral position, after each firing action and with the trigger released.

In particular, the launch vehicle mounting system of the present invention is adapted to support either the first or the second launch vehicle as the arms are at least radially adjustable relative to the mounting frame to at least first and second radial positions corresponding to the booster diameters of the first and second launch vehicles.
Abstract: A line charge for deploying explosive charges across obstacles and mines to clear a safe lane has explosive charges spaced apart on a common detonating cord, and axial passageways in the explosive charges are sized to permit free longitudinal travel of the detonating cord through them. A composite strength member includes an inner fabric sleeve of high strength flexible material covered by an outer sleeve of thermoset/thermoplastic material and contains the explosive charges and detonating cord. Heat-curing the inner fabric sleeve and outer sleeve shrinks and conforms them to the outer contours of the explosive charges and combines the high strength flexible material and thermoset/thermoplastic material. Composite strength member absorbs energy during deployment of the line charge over its entire length and circumference and absorbs more energy prior to structural failure to allow the use of more powerful rocket motors to fly longer line charges from much greater and safer standoff distances.

Abstract: A portable, hand-held forcible entry device is provided for opening locked or barricaded doors in emergency situations. The device comprises a firearm secured to a hollow cylindrical housing. A piston is positioned in a chamber in the housing and drives a striker. An interchangeable tool bit is mounted to the striker. When the firearm is fired, the percussive force causes the piston to move forward in the interior chamber toward the striker. The piston strikes the base of the striker causing the tool bit mounted on the striker to forcibly move forward into a target object, such as a locked or barricaded door. Compression springs are positioned in the chamber to return the piston to the firing position. The device is particularly suitable for use by law enforcement and emergency personnel for forcing locked doors open and for freeing victims trapped in automobile accidents.
