I 1277718 DESCRIPTION OF THE INVENTION Continuation page 发明, invention description In the example, the pipe grab assembly can be inserted in two parts. The first or front pipe grab segment is inserted into the buffalo tube toward the end of the muzzle of the female barrel. This front barrel segment is actually a barrel extension and does not contain any projectiles. The second or rear barrel section contains projectiles and can be inserted into the rear portion of the barrel of the barrel and engaged with the front tube segment to form a complete tube assembly with projectiles and launchers. The barrel assembly can be inserted from the front or rear of the gun barrel depending on the structure of the gun. The barrel assembly can be joined to the caliber of the female tube by a plurality of segments or tabs extending from the barrel assembly to form an interference with the caliber of the mother. The diameter of such spaced segments can be the same as the diameter of the female pipe. Such spaced segments may be constructed of metal or insulating material and may aid in the operation of the launch system. The position of the barrel assembly can be fixed by a one-button system that can be placed at the muzzle, the back of the barrel, or both. Where the bundle of 15 barrels is joined to the tube grab assembly, the outer casing preferably includes a plurality of spaced segments for engagement with the caliber of the barrel. A barrel assembly including one or more barrels may incorporate an electronic transmission system that is hardwired to a firing mechanism external to the barrel. In one embodiment, the trigger mechanism of the female firearm can be adapted to shoot a total of 20 shots from the barrel. Where the spaced segments are used to interface with the caliber of the bullshield, the wiring required to operate the barrel assembly can be maintained within the space defined by the barrel assembly and can be via the muzzle or the rear of the barrel. The segment exits from the mast barrel. Preferably, the launching mechanism can be a single wire that enters from a rear segment of the female barrel. 0 continuation page (inventory note page when not in use, please note and use the continuation page) 1277718 Description of the invention, invention description 5 10 In a second aspect, the present invention provides a barrel assembly for loading a firearm, The firearm has a barrel extension member, wherein the pipe grab assembly has a plurality of projectiles that are axially disposed within a barrel and are individually selectively operative for launching projectiles from the barrel The fired charge is fired, wherein the barrel assembly includes a pipe extension extension engagement device. In a related aspect of the invention, the invention provides a method of filling a weapon, the gun having a barrel extension member, the method comprising the steps of: extending a barrel assembly comprising a plurality of projectiles and a barrel The components are coupled, wherein the plurality of projectiles are axially disposed within a barrel and are accompanied by individually selectively fired charge guns for firing the projectile from the tube, wherein the tube assembly includes a gun Pipe extension part connection

In a preferred embodiment, the barrel extension member engagement means is a chamfered guide section of the barrel assembly that engages the associated surface on the barrel extension. The engagement means using the angled barrel extension member allows the pipe grab assembly to be inserted obliquely into the barrel extension and then aligned with the barrel extension and clamped or held in place. Preferably, the barrel assembly is forced forward so that the tube extension member can be closed. The pipe grab assembly and the barrel extension member can be suitably combined with a locking system for releasably locking the barrel assembly to the extension member. In another embodiment, the pipe grab extension member engagement device can include a segmented segment that engages a corresponding zero-continuation page of the barrel extension member (note that the page is not sufficient for use, please note and use continued Page) 10 1277718 玖, Section of the Invention Description Section. Another specific example is simply adjoining the barrel assembly within the tube extension extension. A sleeve can be placed at the interface between the pipe grabbing assembly and the pipe grab extension to assist the pipe grab assembly in keeping with the barrel extension. In a specific embodiment of the second aspect of the invention, the projectile containing the projectile can have a rod that is coupled to facilitate positioning and locking using the main segments of the barrel of the weapon system. The barrel of this segment. During transport and storage of the barrel segments, the rods can be folded to form a lower profile along the barrel segments. When the projectile's projectile segment is connected 10 to the weapon system, the rod can be raised to aid in the positioning and locking of the barrel segment, much like a conventional rifle. To assist in positioning and locking the pipe grab segment, a key ring set on the pipe grabber assembly can also be used. In a preferred configuration, the key mechanism is also locked to position when the lever is rotated to the locked position. In another embodiment of the invention, the pipe grab assembly is pushed obliquely into the pipe grab extension and then spring loaded into the mechanical locking system and pushed down from the rear to the lock. The same mechanical locking system can also be used as a shelling system for weakly fired barrel assemblies. In another embodiment of the second aspect of the invention, one or more of the spare barrel assemblies containing the projectile can be received on the weapon, typically below the weapon. When the last projectile in the pipe grabbing assembly is fired, the weak pipe grab assembly can be automatically retracted and a spare pipe grabbing assembly is automatically advanced and locked to the position, ready for a new one.

The invention is particularly applicable to the general type of barrels previously described by the inventors of the present application in the International Patent Application Nos. PCT/AU94/00124 and PCT/AU96/00459. The barrel assembly includes a barrel, a plurality of projectiles axially disposed within the barrel, the projectile is operatively sealed to the barrel of the gun, and is used to sequentially fire the individual through the barrel. The individual bombs are filled with gunpowder. The projectile can be round, conventional or dart-like and its flaps can be biased to produce a stable rotation, since the dart is fired from the pipe, which can be a smooth pipe. 10 Filling gunpowder can be in the form of a solid block and is operationally conducive to the separation of the projectile in the pipe. Alternatively, the filling charge can be loaded into a metal or other rigid box, which can include a buried detonator with an external contact device adapted to contact the pre-positioned electronic contact in conjunction with the tube. For example, the detonator can be provided with a contact with a spring 15 that can be retracted to allow the feed into the barrel to be inserted into the barrel and into the barrel bore when in line with the aperture, the aperture being provided for Contact with the paired tube. The outer box can be consumable or chemically assisted in burning the gunpowder if needed. Further, the stack and the combined or separated loading and projecting assemblies of the cassettes can be refilled into the barrel. Each projectile can include a projectile and an extension member means for at least partially defining a powder space. The extension member means can include a spacer assembly extending downwardly from the projectile and immediately adjacent to the adjacent projectile assembly. This extension part device is currently guiding the firing 0 continuation page (please note and use the continuation page when the invention page is not enough) 12 1277718

When the invention is invented, it can assist in the interception of the pipe to support the projectile in the barrel. A partition assembly can extend through the gunpowder space and the projectile, thereby directly passing the adjacent adjacent partition assembly. Transfer compressed 5 fillings. In this configuration, the divider assembly can increase support for the stop and extension member means. The extension member means can be a thin cylindrical rear portion of a projectile. Further, the extension member means can form an operational seal in contact with the bore of the barrel to prevent combustion leakage from passing through the projectile. The divider assembly can include a rigid collar that extends outwardly to enable engagement of the thin cylindrical rear portion of the projectile projectile with the aperture of the pipe grab with an operational seal. Thus, the axial compression charge is transferred directly between the divider assemblies to avoid deformation of the projectile projectile. 15 Complementary wedge surfaces may be provided on the divider assembly and the projectile head, respectively, thereby forcing the projectile head to engage the caliber of the barrel corresponding to the relative axial compression between the divider means and the projectile. In such an arrangement, the projectile and divider assembly can be loaded into the barrel and subsequently cause an axial displacement to ensure a good 20 seal between the projectile and the barrel. A suitable extension member device can be forced into engagement with the barrel of the barrel. The projectile can define a tapered opening at its rear end that can accommodate a complementary tapered socket that is disposed on the leading end of the divider assembly. Relative movement between the projectile head and the complementary tapered socket 0 continuation page (please note and use the continuation page when the invention page is not available) 13 1277718 Description of the invention Continued page, invention description caused to the projectile Radial expansion force. The barrel may be non-metallic and the caliber of the barrel may include a recess that completely or partially houses the ignition. In this configuration, the barrel houses an electrical conductor that facilitates electrical connection between the control device and the ignition device. 5 This structure can be utilized in discard-type pipe grab assemblies that have a limited launch life. The launcher and its one or more control wirings can be fabricated integrally with the barrel. Alternatively, the barrel assembly can include an ignition port within the barrel and an ignition device can be placed outside of the tube and adjacent to the firing port. Non-metallic 10 External pipe grabs can be around this pipe. The non-metallic outer tube may include a recess adapted to receive the ignition device. The outer barrel can also house an electrical conductor that facilitates electrical connection between the control device and the ignition device. The outer barrel can be in the form of a laminated plastic tube that can include a printed circuit laminate for the ignition device. The end of the projectile may include a skirt surrounding the inwardly reducing recess, such as a tapered recess or a partial spherical recess or the like, into which the filled powder portion may extend, and the projectile encircling the recess rearwardly Movement will cause radial expansion of the projectile skirt. This rearward movement can occur by compression caused by the projectile moving along the 20 rearward wedge movement of the pre-filled portion of the gunpowder, possibly due to metal flow from the relatively solid projectile leading portion to its less solid skirt. And it happened. Alternatively, the projectile may have a circumferentially sealed peripheral seal edge or collar that deflects outwardly to the continuation of the caliper as the projectile moves backwards (note that the page is not sufficient for use, please note and use continuation) Page) 14 1277718

玖, invention instructions Sealed connection. Further, the sealing action can be produced by inserting the projectile into the heated barrel which is shrunk in the individual sealed portions of the projectile. The projectile can include a relatively rigid mandrel portion that cooperates with the deformable annular portion. The deformable annular portion is moldable about 5 mandrels to form a single projectile that depends on the metal flow between the tip of the projectile and its tail to expand outwardly around the mandrel portion to the barrel The caliber seal is connected. The projectile assembly can include a rearwardly expanding anvil surface that supports the sealing neck surrounding it and is adapted to radially expand to engage the pipe caliber seal as the projectile moves forward through the pipe. In such a structure, preferably, the filling powder has a cylindrical leading portion which is w to the flat end surface of the adjacent projectile. The projectile can be adapted to be seated and/or provided in the form of a circumferential groove or in an annular rib or caliber in the caliber, and can include a metal jacket that receives at least the outer end portion of the projectile. The projectile can have a retractable peripheral retaining ring that extends outwardly into the annular groove in the barrel and that retracts within the projectile upon launch to allow it to pass freely through the barrel. The electronic ignition 20 for the charge of the continuous firing gun barrel assembly preferably includes the step of igniting the pilot charge by transferring the ignition signal through the stacked projectiles. The ignition of the pre-filled gunpowder can be filled with the next batch of filled gunpowder for activation by the next ignition signal. Appropriately, by inserting individual insulation fuzes placed between the generally close electronic contact points, all filling guns are renewed. (Note that the page is not sufficient for use, please note and use the continuation page) 1277718 Description of the invention DESCRIPTION OF THE INVENTION The end of the barrel that has been filled is removed inwardly. These fuses are installed for combustion to ensure that the contacts are close when the appropriate trigger signal is transmitted, and that each insulation fuse is opened to individual pilots to fill the guns for ignition. 5 The ignition of the gunpowder can be accomplished electronically or by ignition using conventional launch pin methods, such as the use of a central-shot detonator to ignite the outermost projectile and the subsequent ignition of the control to cause sequential firing of the subsequent filled charge. This can be achieved by controlled back venting of the combustion gases or by 10 controlled combustion of the fuse column of the projectile. In another form, the ignition system is electronically controlled relative to the filling of the charge with the detonator that is triggered by a different firing signal. For example, the detonators in the stacked charge charge can be ordered for increased pulse width ignition requirements, whereby the electronic control can selectively transmit the pulse pulses of increased pulse width for sequential firing in a pre-selected time sequence. Fill the gunpowder. Preferably, however, the filling of the gunpowder is carried out by a set of pulse width signal ignitions and the combustion of the pre-filled gunpowder to fill the next batch of filled powder for priming by the next pulse. 20 Most projectiles can be fired, for example, simultaneously, or in rapid succession, or with repeated manual actuation of the trigger. In such an arrangement, the electronic signals may be transmitted from the outside of the barrel or may be transmitted through the added projectiles, which may be in close proximity to each other to continue through the circuit of the tube, or adjacent to each other for electrical contact. The projectile can have a control circuit or it can be continued with the 0 page (please note and use the continuation page when the invention page is not available) 16 1277718

发明, INSTRUCTION DESCRIPTION The device is or is manufactured integrally with a barrel, such as those described by the inventor of the present invention in a prior international patent application. In this configuration, the 40 mm pipe 21 can be converted into an electronically controlled 20 mm weapon. The Steyr rifle 30 shown in Figures 7, 8 and 9 includes 5 an upper front barrel section 31 and a rear tube section 32. After the rear segment, the barrel assembly 33 houses a plurality of projectiles 35 and has a chamfered leading end 34 for preparation for engagement with the rear end of the barrel extension member 31. The upper 40 mm barrel is held in position by a cover 37 which is identical to the barrel of the tube assembly 33 containing the projectile 35. Figures 10, 11 and 12 show FM with 40 mm upper barrel 41 -FMC to bless 40. As shown in Fig. 12, the 40 mm upper pipe grabber is divided into two sections, grabbing the port 42 and/or its barrel extension 43 and retaining it within the outer casing 44. The rear barrel section 15 includes a barrel assembly 45 containing a projectile 46 that is disposed at the chamfered leading end 47 to permit preparation for engagement with the complementary trailing end 48 of the barrel extension member 43.

发明, invention description, can provide significant advantages in durability, accessibility and cost, especially during manufacturing, can be extended to the operational capabilities of firearms or other weapons. The second aspect of the invention allows the barrel assembly preloaded projectile to be easily attached to the barrel section of the weapon. Once all projectiles have been fired, the new barrel assembly containing the projectile can then be discarded and the projectile can be attached to the weapon system. Because the rear section with the projectile can also be used as part of the barrel, the weight of the projectile can be reduced by 10%. Quality control can be enhanced by pre-loading the projectile in the segment of the pipe grab. The transport and storage of projectiles and gunpowder can also be made easier. In a special application, the single-use grenade's grenade on a one-step weapon is generally hung below the main pipe, replacing the 5 or 6 projectile with a higher muzzle speed of 15 Degree of electronic shooting barrel. The conventional grenade throw-off cartridges need to be reloaded after each use, requiring the target to be re-targeted and re-targeted, including any misalignment errors in the previous shot. The present invention reduces reloading motion, provides improved accuracy, and a better trajectory approach when used, wherein only 20 adjustments to the aiming error are required while the weapon is still aiming at the target. Most importantly, this weapon delivers a shot firepower more quickly and accurately within 10 seconds of the key to connecting the military.
