Abstract: Disclosed is a bullet with separable elements or projectiles which upon impact with an animal or human target, this bullet, having a high kinetic energy and under the influence of inertia, divides into 2-6 elements. The respective linear velocities of the elements are influenced by the variations in size and shape of the elements. When the bullet hits the target, the change in momentum is sufficient to break the individual or combination of internal or external connectors such as the Kevlar belts or internal rod connectors. Based on the differences in linear velocities, shapes and/or sizes the side elements proceed to varying depths within the target causing greater damage compared to a single trajectory bullet.

Abstract: This invention relates to power engineering, and more exactly, to engine building, and, in particular, to rotary internal combustion engines and pneumatic and hydraulic pump units. The invention helps to simplify the design of the rotary machine, reduce its material consumption rates, improve the manufacturing process thereof, and lower unit costs, all other conditions being equal, by using less complicated and less expensive manufacturing processes. The rotary machine comprises a housing in the form of two intersecting cylinder parts of different diameters having parallel axes; a rotor received in the housing coaxially with the smaller-diameter cylinder and comprising at least two segmental rotor parts provided with annular rotor covers. At least two pairs of annular elements are provided. Pivotal elements are interposed between the annular elements of each pair. A driving member is accommodated movably in the openings of the pivotal elements.
