The Hatsan 135 QE Vortexis a gas piston-powered gun. A gas-powered gun works the same as a spring-powered one; however; in this case, the coiled spring in the chamber is replaced with a gas strut. The air in the strut is already compressed and when the gun is cocked, more pressure...
The optical - relay comprises a secondary mirror (m2) and a mirror tertiary (m3), each having a central opening (12, 13) and arranged coaxially with the primary mirror (m1). The secondary mirror (m2) receives the image reflected by the primary mirror (m1) through the central opening (...

air is first ingested and then compressed in the engine’s cylinders. After the inlet air is compressed, the pressure in the cylinder is very high. Assume this process to be followed by an isentropic compression stroke [a2] , the pressure in the cylinder after compression can be easily pr ...

Traditional ballistocardiograph systems are bed-based: the patient is positioned on a sensible movable and instrumentated bed: due to force, the bed oscillates and by measuring these movements, velocities, accelerations, and forces can be easily calculated. This approach measures the force component...
