Abstract: A system for firearm barrel modification includes a firearm, a collar and an auxiliary barrel. The firearm has a barrel with holes extending inward from the first muzzle end. The barrel has rifling. The collar surrounds the barrel to serve as a securing anchor for an auxiliary barrel. A sleeve slidably engages onto the firearm from the muzzle. The sleeve contains a tubular component, serving as a barrel extension. The tubular component extends from within the sleeve to form a second muzzle at the opposite end. The mating end of the barrel extension is situated within the sleeve. It butts up against the muzzle and is aligned with the rifling of the gun. Alignment rods protrude from the mating end of the tubular component and insert into corresponding holes at the muzzle end of the firearm. A spring member attached to the sleeve sets in place over the collar.

Abstract: A bullet defines a chamber and mechanism for extending an explosive body from the chamber. The chamber has a broader top portion than a lower portion. The bullet further defines a channel passage leading out of the top end of the bullet. The bullet contains the explosive body slidably engaged within the channel passage. A shaft is connected to the body and passes down from the body into the lower portion of the chamber. A thrust plate is connected to the shaft end in the chamber. The thrust plate is spring metal and when the cartridge is fired, the thrust plate rises pushing the body so that it extends from the leading end of the bullet. When the thrust plate rises to the second portion of the chamber, it springs open to prevent subsequent downward motion of the thrust plate and consequently prevents subsequent retraction of the body during flight.

Abstract: A self-propelled explosive system is configured to fit within a barrel mounted on a tank. The system includes: a carrier body defining an interior volume; an explosive within the interior volume; a wheel extending from the carrier body to propel the system to a position within the barrel; a foot extensible from the carrier body, preferably so as to hydraulically lock the system in place within the barrel; a proximity fuse at the front end and the rear end of the carrier body to set off the explosive if tampering is detected; a motor operably connected to the wheel to rotate the wheel and propel the carrier body to a desired position within the barrel and to extend the foot from the carrier body to press against the inner wall of the barrel and lock the carrier body in place.

Abstract: An auxiliary projectile for a firearm includes: an exhaust vessel to allow a bullet to pass through it yet capture muzzle blast, a barrel socket to slide onto the barrel of the firearm; and a ring magnet to attach to the end of the barrel. The exhaust vessel has opposed openings at each end to permit the unimpeded passage of the bullet discharged from a regular cartridge for a firearm. The opening nearest the muzzle is a muzzle-end opening and the opposite opening is an exit-end opening where the bullet exits. The barrel socket is attached to the exhaust vessel so as to surround the muzzle-end opening and project outward therefrom. The barrel socket is what slides over the muzzle end of the barrel of the firearm. The ring magnet fits within the barrel socket and is what attaches to the muzzle end of the firearm.

Abstract: A capsule is configured to have the outward appearance of a cartridge for a firearm and the capsule is designed to explode within a chamber of a firearm and disable the firearm when fired from the firearm. The capsule includes a casing; a bullet shaped container; a high explosive and a primer. The casing is made to fit within a firing chamber of the firearm. A bullet-shaped container holds a high explosive and fits within the casing to give an outward appearance of an ordinary bullet in a regular cartridge for that firearm. The primer is accessible to a firing pin of the firearm acting on the casing. The primer includes a small charge of a mixture in contact with the high explosive such that when the primer is struck by the firing pin of the firearm, the primer causes the high explosive to detonate disabling the firearm.

Abstract: A tool box assembly for a truck is formed of nested boxes that telescope out to add additional storage space. There is an outer box and one or more inner boxes slidably engaged so that the inner boxes telescope out of the outer box, which is normally fixed to the truck's cargo bed across the width of the truck so that when they slide out, the inner boxes move out horizontally toward the rear end of the truck. The rear wall of each inner box locks in extended telescoped position to fill in the hole in the wall created by its having been telescoped out. Each inner box preferably has a top cover that slides around the bottom and sides of the inner box to close the top opening of the inner box.

Abstract: A firearm flame thrower combination includes a firearm, a cartridge that is dischargeable from the firearm; and a flame thrower attached to the firearm. The flame thrower has a battery; ignitable fluid; a reservoir holding the ignitable fluid; a nozzle that optionally pivots; a high-pressure pump operable to pump the ignitable fluid from the reservoir and to eject a stream of the ignitable fluid out of the nozzle. The stream is ignitable from muzzle flash exiting the muzzle upon firing of the cartridge in the firearm. Movement of the trigger may automatically activate the high-pressure pump. A radio-frequency controller may be used to emit a radio-frequency signal to start the high-pressure pump. An off switch may be included.

Abstract: A system includes an incomplete cartridge for a firearm and a field-selectable capsule for the cartridge. The capsule contains a product that may tag a person for tracing, induce sleep, cause disease, or have other effects. Capsules are preferably removably adhered to a strip with each strip of capsules potentially serving a different purpose. The incomplete cartridge includes a bullet that has an opening at the payload end. The opening receives and retains a capsule upon insertion. The capsule is made of a frangible material that releases the product upon impact. The capsule may be formed with a snap-in ridge extending from its exterior wall, which snaps into a complementary recess in the bullet opening. Alternatively, the capsule may be coated with a contact adhesive so that it sticks to the bullet wall defining the opening. A peel-off covering atop the strip shields the contact adhesive from contamination.

Abstract: A cartridge for a firearm has a bullet that defines an internal chamber. The chamber has a broader top portion than a lower portion. The bullet further defines a channel passage leading out of the top end of the bullet. The bullet contains an arrowhead slidable engaged within the channel passage. A shaft is connected to the arrowhead and passes down from the arrowhead into the lower portion of the chamber. A thrust plate is connected to the shaft end in the chamber. The thrust plate is spring metal and when the cartridge is fired, the thrust plate rises pushing the arrowhead so that it extends from the leading end of the bullet. When the thrust plate rises to the second portion of the chamber, it springs open to prevent subsequent downward motion of the thrust plate and consequently prevents subsequent retraction of the arrowhead during flight and after impact.

Abstract: An ammunition system for a firearm includes a cartridge for a firearm, a muzzle-loaded cartridge attachment, a magnet, and a magnetic material. The muzzle-loaded cartridge attachment is loaded into the barrel after the cartridge is loaded in the usual manner. The two are adhered together by magnetic attraction. The cartridge has the magnet, the muzzle-loaded cartridge attachment has the magnet, or both have magnets aligned to draw the two together. When one magnet is present between the two, then the other must have a magnetic material to be drawn to the magnet. To enable more than one muzzle-loaded cartridge attachment to be added, a third magnet may be used within the muzzle-loaded cartridge attachment at the end opposite the cartridge to exert a magnetic field extending toward the muzzle, which will hold the next muzzle-loaded cartridge attachment added to the barrel.

Abstract: A portable fluid injector is a device that burns through and injects a fluid into a metal enclosure. A miniature cutting torch mounted to a magnetic frame. The cutting torch has a minimum of three cylinders, two for cutting gases like oxygen and acetylene, and one for an injection fluid, such as a sleep-inducing gas. The device can be started remotely after it is attached to the metal enclosure. The miniature cutting torch has a nozzle mounted to the end of a pivot arm. An igniter or spark generator is activated to ignite the cutting gases. A guide tube extends below the nozzle such that the guide tube can progress into a hole cut below the nozzle. The guide tube may serve as a means to tell when the hole is complete. The guide tube may also convey the injection fluid through the hole.

Abstract: A magazine for a firearm is adjustable for cartridge capacity using a thumb slide to select the quantity of cartridges to be held by the magazine. The thumb slide is operable in a vertical slot and below the carriage pushing up on the bullets. The thumb slide protrudes into the internal chamber through the vertical slot so as to form an obstruction preventing downward movement of the carriage beyond the obstruction. Alternatively, the thumb slide raises a platform on which a segmented spring rests. When the platform is raised, it reduces available storage in the magazine. If a capacity selection requires a smaller spring, then spring segments are removed. A set screw locks the thumb slide in place. An indicator bar shows through holes in the magazine indicating the number of cartridges remaining in the magazine. A bolt and nut is introduced to permanently prevent further adjustment.

Abstract: A weapon system includes a long gun, such as a rifle or a shotgun, a handgun, and a bracket secured to the rifle or shotgun around the barrel. The bracket permits swiveling and firing the handgun while attached to the long gun. The bracket includes a swivel ball joint below the long-gun barrel and an attachment brace that releasably connects the swivel ball joint and the handgun. The handgun may be a semi-automatic pistol where a slide moves back and forth when fired. The attachment brace has a top section and a bottom section. The top section goes around the slide so that it does not interfere with its movement. The bottom section contacts the handgun below the slide to securely attach the handgun to the rifle or shotgun.

Abstract: A shotgun cartridge system includes a shotgun shell and a detachable cap. The cap fits within the casing atop the open end so as to close the casing and prevent the projectiles from falling out. An edge recess on the cap enables finger-nail removal of the cap. An injection port enables injection of a coating substance onto the projectiles. The inside wall of the casing may have a projection to snap connect the cap in the casing. The cap then has a mating projection recessed into the cap-wall and structured to snap in place below the projection on the casing when the cap-wall is slid into the casing. Alternatively, the projection is placed so as to form a thread around the inside wall and the cap's mating projection engages the thread when the cap-wall is slid, rotated and tightened against the thread.

Abstract: A weapon system includes a first handgun, a second handgun and a clamp removably connecting the first handgun and the second handgun. The clamp includes a bracket securing to the first handgun over the grip and above the magazine butt plate. The clamp has a ball joint connected to the bracket below the magazine butt plate. The clamp includes a beam connected to the ball joint. The clamp includes an attachment brace connected to the distal end of the beam. The attachment brace releasably holds the second handgun. The attachment brace is tighten-able to the second handgun such that the muzzle of the second handgun can be adjusted to a rotatable position in three dimensions. The second handgun can also be fired when in such rotatable position.

Abstract: Telescoping cap-rails for a trailer are extensible, hidden vertical pillars within two opposing side walls of a trailer. The extensible vertical pillars are connected at the top by a cap-rail sitting atop the side walls. A set of telescoping pillars is added to each of the two side walls bordering the bed of the trailer. When extended, either manually or via a powered option, the vertical pillars, which are joined at the top by the cap-rail, form a skeleton structure of a tall side wall. The cap-rail is a stabilizing connection. The skeleton structure can be used alone or with added horizontal beams inserted through horizontal access ports in the extended pillars. Preferably, the access ports allow passage of a standard 2×4 or other stake through the pillars to create added structural stability to each set of telescoping pillars.

Abstract: An L-shaped platform system for female breasts has a vertical leg and a horizontal leg for each breast, and a strap that holds the legs in place. The vertical leg rests against the torso under a human breast. The horizontal leg extends outward from the torso under the human breast supporting it against the pull of gravity. The strap may have two free ends that fit around the human body and attach together like a bra. Each vertical leg may be embedded within the strap so as to fix the position of each L-shaped platform on the strap. Alternatively, the vertical legs have slots that permit weaving the strap through the vertical leg and permitting adjustment of the position of the L-shaped platform. A spring hinge may be added to join the horizontal leg to the vertical leg so that the horizontal leg can pivot downward.

Abstract: Telescoping side rails for a pickup truck are extensible, hidden vertical pillars within each side wall of a pickup truck. The extensible vertical pillars are connected at the top by the side rail sitting atop the side walls.

When extended, either manually or via a powered option, the vertical pillars, which are joined at the top by the side rail, form a skeleton structure of a tall side wall. The side rail is an added stabilizing connection. The skeleton structure can be used alone or with added horizontal beams inserted through horizontal access ports in the extended pillars. Preferably, the access ports allow passage of a standard 2×4 or other stake through the pillars to create added structural stability to each set of telescoping pillars.

Abstract: A magazine for a firearm holds cartridges in three sections: a top section, a middle section and a bottom section. The top section is detachable. The middle section has a smaller width and depth than the bottom section so that the middle section can be inserted into the bottom section of another similarly formed magazine. A removable bottom cover closes the bottom section. A spring with removable segments rests on the bottom cover. A c-shaped member fixed to each spring segment permits adding segments. Two magazines may be combined by removing the top section of a second magazine, detaching the bottom cover of a first magazine, removing a spring segment of the second magazine, connecting the shorter spring to the spring of the first magazine; and slidably inserting the middle section of the second magazine into the bottom section of the first ammunition magazine over the larger spring.
