Abstract: The product includes an upright launch tube adapted to be self-supporting on a horizontal surface and a self-propelled aerial pyrotechnic device adapted to be received within a fairly closely confined relationship within the tube in preparation for launch. In its preferred form, the tube is slightly taller than the aerial device so that the aerial device is fully received within and surrounded by the side wall of the tube in the launch mode, except for a long fuse leading to the engine of the device and hanging out over the open upper edge of the tube. Except for a tapered nose cone, the device is substantially the same cross-sectional width along its entire length, including the lower regions thereof which are occupied by a plurality of stabilizing legs that support the device in an upright condition within the tube and balance the device during flight.

Abstract: A breech block firearm safety device for the prevention of injury to children having unauthorized access to loaded firearms. This device will also protect gun owners from injury due to mishandling or the dropping a loaded weapon. The safety device utilizes a two piece blocking assembly having a breech member and a bore member. The breech member is inserted into the breech just as you would insert a live round to arm a weapon. The bore member is inserted into the muzzle of the firearm and screw connected to the breech member using special tooling. The chamber blocking assembly can be easily extracted but the overall length is such that the end of the bore member remains in the breech making ejection impossible. The assembly can only be returned to the breech, making manual or automatic loading of live ammunition impossible. When the above safety device is installed in a revolver the overall length prevents the rotation of the cylinder and prevents the loading of live ammunition into firing position.

Abstract: A system and apparatus for preventing unauthorized access to a trigger of a firearm comprises a database of PIN numbers associated with a plurality of trigger locks and access tokens, each corresponding trio being represented by a common identification code. At a point of purchase, a consumer receives a two-piece trigger lock secured about the trigger of a purchased firearm as well as an access token. Each token includes a unique number or configuration of ferro-magnetic wires. Each trigger lock includes a magnetic read head which generates voltage pulses when a token is positioned in close proximity thereto. This positioning causes the ferro-magnetic wires to switch magnetic states, thus invoking electromagnetic impulses. If a background check of the firearm purchaser, initiated at the point of purchase, is approved, a central computer coupled to the database and to a computer network displays a personal identification number (PIN).

Abstract: A semi-automatic handgun is disclosed including a frame having a barrel housing mounted thereon. A barrel is movably mounted on the barrel housing and has a cartridge chamber at its rearward end for receiving a cartridge therein. The barrel is movable between a rearward position and a forward position with respect to the barrel housing and is normally in its rearward position. The barrel moves forwardly in a straight line from its rearward position upon firing of the cartridge in the chamber to counteract the rearward energy of discharge, thereby reducing recoil. The handgun may be fired in either a single action or double action manner. The firing hammer of the handgun is re-cocked, upon firing of the cartridge, by means of a movable piston having a firing pin positioned therein with the firing pin engaging the hammer to move the hammer to its re-cocked position.

Abstract: Two-way pressure release valves in a shutter reduce the force needed to rotate it from a torpedo tube while the submarine is underway at high speeds. The valves are each mounted in a separate aperture in the shutter and have a pair of biasing springs that hold opposite end surfaces coplanar with outer and inner surfaces of the shutter to prevent generation of objectionable flow-noise while underway. When the shutter is rotated to expose a muzzle door of a torpedo tube, the valves are automatically displaced by pressure differentials created to free pathways for pressure equalization. The water flowing through the valves eliminates the pressure differentials, and consequently, reduces the total amount of force that would otherwise be needed to rotate the shutter.

Abstract: A deployable nose is used on an underwater vehicle to provide a shorter length when in a retracted position and to provide a reduced drag when in the deployed position. The deployable nose includes a plurality of nose sections and a deployment mechanism that moves the plurality of nose sections from the retracted position to the deployed position. The nose sections include a base nose section attached at the end of the underwater vehicle, an outer nose section having a rounded contour, and one or more intermediate nose sections between the base nose section and outer nose section. In the retracted position, the outer nose section and one or more intermediate nose sections are retracted generally within the base nose section. In the deployed position, the outer nose section and intermediate nose sections extend outwardly from the base nose section and interlock proximate the edges of the nose sections to form the deployed nose.

Abstract: An aerial fireworks product has an exploding part that produces desired sights and sounds upon reaching an appropriate height above the ground, and a non-exploding part that returns to earth following the explosion. An air brake as part of the device is integrated into the structure in such a manner that it provides little or no in-flight drag during launching of the device. However, upon explosion, the brake bursts out into petals or flaps that remain secured to the non-exploding part so as to create additional air drag to retard the descent of the non-exploding part. In its preferred form, the brake is in the nature of a paper collar secured to the stabilizing base of the product yet positioned in close proximity to the exploding part so as to burst into the air drag-creating configuration upon denotation of the exploding part.

Abstract: A phosphorescent or light-reflective member is disposed on a holder supporting an elongated light-gathering optical fiber formed of a light-gathering fluorescent plastic material. The sight is adaptable for use on rifles, handguns, bows, and other weapons requiring an aiming indicia. The light-gathering fluorescent optical provides a brilliant dot that is readily identifiable under bright light conditions, and the phosphorescent or light-reflecting member provides a supplemental light source which serves to provide an illuminated dot under low-light or dark conditions. The sight 10 effectively solves the problem of providing electrically-powered light sources for illumination of the aiming indicia under low light or dark conditions, or the requirement to precisely align the fiber or hollow tube with a light source disposed at the distal end of the fiber or tube spaced from the viewing end of the fiber or tube.
