| 168 | Pistol having a barrel with synchronized cams | US12987317 | 2011-01-10 | US08621976B1 | 2014-01-07 | Yury Karfiol; John Goliber |
| A semi-automatic pistol is provided having a barrel, a frame and a slide. The slide is adapted for linear motion along the frame during a firing sequence and has a forward end and a block end. The forward end has an upper cam follower surface and a lower cam follower surface on the inside surface adjacent to the barrel. The barrel has a ramp cam surface adjacent to the chamber end of the barrel to effect locking and unlocking of the barrel relative to the slide during the firing sequence, a bottom cam surface and a top cam surface. The bottom cam surface and the top cam surface extend from the front end toward the chamber end of the barrel and each have undulating surfaces that moves against the lower cam follower surfaces of the slide to cause oscillation of the barrel while the slide moves during the firing sequence. | ||||||
| 169 | Reduced lethality gun | US13102618 | 2011-05-06 | US08516729B2 | 2013-08-27 | John Hayes; David J. W. Lovinger |
| A gun that has a plurality of frangible barrels. At the proximal end of each barrel is a chamber that receives a cartridge. The cartridge has a reduced charge as compared to a conventional cartridge. Each barrel may have an inner sleeve formed from a malleable material. The out member of each barrel is comprised of a rigid material such as, but not limited to, a filled plastic. The inner sleeve is rigid enough to withstand the pressure of the reduced charge cartridge when fired, but is malleable enough to expand from the pressure generated by a standard charge cartridge. When the inner sleeve expands, the outer member fragments and destroys the weapon. The expansion of the inner sleeve and fragmentation of the outer member upon firing a standard charge reduces the propelling force in the bullet. As a result, the weapon is destroyed and the bullet is fired with a greatly reduced force. The barrels on the gun don not rotate. The hammer is mounted in a revolving mechanism that is rotated in a circular path from one barrel to the next when the trigger is pulled. Pulling the trigger also compresses and then releases a revolving member that forces the hammer into contact with one of the firing pins. | ||||||

| A methodology and system for applying coatings onto the interior surfaces of components, includes a vapor creation device, a vacuum chamber having a moderate gas pressure and an inert gas jet having controlled velocity and flow fields. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved. The carrier gas flow and chamber pumping rate control the downstream pressure. The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. These collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit. | ||||||

| 176 | Composite firearm barrel | US11360197 | 2006-02-23 | US07934332B2 | 2011-05-03 | Vernon R. Briggs |
| A composite barrel for a firearm and method for forming by forging. The barrel includes at least two materials joined together by forging. In a preferred embodiment, at least one material is preferably lighter in weight than the other material. The barrel may include an inner tube and an outer sleeve. The inner tube defines a bore that provides a bullet path and in one embodiment may be made of steel or alloys thereof. The outer sleeve surrounds the inner tube and in some embodiments may be made of aluminum, titanium, or alloys of either thereof. The tube preferably includes an exterior surface containing recessed areas therein for receiving material displaced from the outer sleeve by the forging process. The preferred barrel forming method generally may include inserting the tube into the sleeve, striking an outer surface of the sleeve, and deforming the sleeve to force material to flow into the recessed exterior surface of the tube to bond the tube and sleeve together. The method of forming may be used to produce long and short barrels for rifles and handguns respectively, and more broadly to produce other composite components unrelated to firearms. | ||||||
| 177 | Multivalve hypervelocity launcher (MHL) | US11327479 | 2006-01-09 | US07775148B1 | 2010-08-17 | Patrick P. McDermott |
| Launching payloads at high velocity uses high-pressure gas or combustion products for propulsion, with injection of high pressure gas at intervals along the path behind the payload projectile as it accelerates along the barrel of the launcher. An inner barrel has an interior diameter equal to the projectile diameter or sabot containing the projectile. An outer casing surrounds the inner barrel. Structures at intervals attach the outer casing and the inner barrel. An axial gas containment chamber (AGC) stores high pressure gas between the inner barrel wall, the outer casing wall, and enclosure bulkheads. Pressure-activated valves along the barrel sequentially release the high pressure gas contained in the AGC in to the barrel to create a continuously refreshed high energy pressure heads behind the projectile as it moves down the barrel. A frangible cover at the exit end of the barrel allows the barrel to be evacuated prior to launch. The launcher is rapidly recyclable. The valves close automatically after the projectile has exited the barrel, allowing a new projectile to be introduced into the breech and the AGC to be recharged with high-pressure gas. | ||||||
| 178 | Method for making a barrel front for a paintball marker | US11890146 | 2007-08-06 | US20090038601A1 | 2009-02-12 | Kenneth K. Anderson |
| Disclosed is a method for making a non-metallic, fiber-reinforced barrel tube having particular application for use in a barrel system to be attached to a paintball marker in order to direct paintballs propelled by the marker towards a target. A mandrel is first dipped in a releasing agent. The mandrel is then coated with a thin layer of metal (e.g., nickel or chrome) by means of a nano vapor deposition process. Next, a fiber-reinforced resinous sheet is wrapped over the thin metal layer to establish a tube therearound. A heat-sensitive plastic tape is wound around the tubular resinous sheet. The mandrel is heated in an oven to cause the thin metal layer to bond to the tubular resinous sheet. At the same time, the heat-sensitive tape shrinks to squeeze any air bubbles from the resinous sheet. After heating and curing, the mandrel is pulled outwardly from the tubular fiber-reinforced resinous sheet to produce a hollow, cylindrical barrel tube ready for cutting to size and machining so as to be coupled to the paintball marker. | ||||||

| Provided is a methodology and system for applying coatings onto the interior surfaces of components. The approach comprises a vapor creation device (for example an electron beam or laser that evaporates a single or multiplicity of solid or liquid sources), a vacuum chamber having a moderate gas pressure (between about 10−4 to about 103 Torr) and a inert gas jet having controlled velocity and flow fields of gas jet. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved (i.e. the gas pressure prior to its entrance into the processing chamber through the nozzle). The carrier gas flow and chamber pumping rate control the downstream (or chamber) pressure (i.e., downstream of the nozzle). The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. The carrier gas molecular weight (compared to that of the vapor) and the carrier gas speed controls its effectiveness in redirecting the vapor atoms via binary collisions towards the substrate. The speed and flux of the atoms entering the chamber, the nozzle parameters, and the operating chamber pressure can all vary leading to a wide range of accessible processing conditions. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. Under certain process conditions these collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit. | ||||||
