    • The invention relates to rifled and smoothbore firearms and can be used in barrel-mounted devices for firing in the air and in the water. The inventive barrel-mounted device for firearms comprises a unit for joining to the barrel, a cap and a starting part with gas vents. The starting part bore is the continuation of the barrel bore, and there are N≧1 compartments formed between the casing and the starting part. Each compartment includes at least two gas vents and provides the possibility of gas exhaust from the starting part bore to the compartment through the first of the mentioned gas vents and gas exhaust from the compartment to the starting part bore through the second gas vent. The compartment length is 0.5-3.0 of the bore caliber and in the cross-section plane of the barrel-mounted device the minimal cross-section area of N≧1 compartments, designed for the gas flow between gas vents, ranges within 0.4-4.5 of the barrel bore area. The barrel-mounted device can comprise a muzzle compartment, which projects beyond the muzzle face of the starting part and has a front wall with a muzzle opening. The diameter of the muzzle opening equals to 1.05-1.2 of the barrel bore caliber. The said invention makes it possible to reduce recoil momentum, shot blast and muzzle flash while firing in the air, as well as to reduce recoil momentum and hydraulic impact in the course of underwater firing.

    • A coupler for use in sealing a joint between two pipes. The coupler is comprised primarily of two center sections and two end caps. The two center sections are engagable with one another and the two end caps are engagable with the center sections. Gasket rings create seals between the two center sections as well as between the two center sections and the cap rings. The center sections are dimensioned to create a volume of space within the coupler, thus permitting the coupler to accommodate offset joints. The gasket rings between the cap rings and the center sections can be longitudinally spaced apart, minimizing the angular deflection of the coupler with respect to the pipes when the pipe joint is offset. The center sections and end caps can be lockably engaged.
    • 用于密封两个管道之间的接头的联接器。 耦合器主要由两个中心部分和两个端盖组成。 两个中心部分可以彼此接合,两个端盖可与中心部分接合。 垫片圈在两个中心部分之间以及两个中心部分和盖环之间形成密封。 中心部分的尺寸设计成在耦合器内产生一定的空间,从而允许耦合器适应偏移接头。 在盖环和中心部分之间的垫圈环可以纵向间隔开,当管接头偏移时,使联接器相对于管的角度偏转最小化。 中心部分和端盖可以锁定接合。

    • The invention relates to ammunition for missile weapon and firearm. The cavitating core of the invention comprises a head part conjugated with a secant nose surface along the cavitating edge, a central part, and an aft part with a gliding surface, wherein the caliber of the core is defined by the maximum diameter of the circle describing the core cross-section. The contour line enveloping the cross-sections from the cavitating edge to the core caliber in the plane of the core axial longitudinal section is limited by the dependence: Dx=d×[1+(1x/d)×(2×sin φ/π)1/N]N, where Dx—is the current diameter of the core enveloping contour R, mm; d—is the cavitating edge diameter, mm; Lx—is the current distance from the cavitating edge to the core caliber, mm; φ=60° . . . 270°— is the apex angle of the tangents to the secant nose surface at the points of its conjugation with the cavitating edge measured from the side of the head part; N=(2π/φ)0.4 . . . (2π/φ)0.2— is the core volume factor, wherein the core caliber is equal to the current diameter of the core enveloping contour Dx. As a result the invention makes it possible to increase the effective distance for hitting underwater targets when shooting from the air to the water and/or during underwater shooting using arbalests, harpoon guns, artillery, small and sporting-and-hunting weapons.
