Abstract: The instant invention relates to a displacement-type rotary system steam-turbine engine that among other mainly functions as a displacing-type steam engine. Through the partial utilization of the kinetic energy generated by the impinging steam molecules upon the rotor blades said invention functions additionally similar to a radial flow turbine.

Abstract: The instant invention relates to a valveless bi-chamber rotary steam engine with turbine effect comprising two sets of rotor blades of which each set of rotor blades rotates around its own eccentric point on a stationary mutual crank shaft within a semicircular engine housing. A drum-type rotor is concentrically mounted within the engine housing thus forming two diametrically opposed radial chambers. The said two sets of rotor blades move through equidistant slots arranged within the drum-type rotor thus varying the space volume of the respective radial chamber where through the introduction of a pressurized medium through diametrically arranged inlet ports the generation of a torque moment is achieved.

Abstract: Electromagnetic projectile accelerator comprising stationary coreless coils arranged in a row thus forming a tube. On the interior wall surface of said tube electrically opposite poled plates are mounted establishing an electric field.The magnetic projectile moving through the said electric field generates an alternating switching mode in the respective electromagnetic coils whereby the acceleration of the projectile within the tube is performed.
