Abstract: A burner that includes a primary air or gas duct delimited by an exterior wall and a concentric interior wall of axis X and ducts for radial primary air or gas injection is described. The air or gas duct includes a ring that is rotationally mobile and has axial protrusions constituting distributors which collaborate with the radial primary air ducts arranged on the interior wall and form two passages of different angles in each duct. Rotating the ring making it possible to vary the angle of injection of the radial primary air. Thus, the regulation is situated just at the tip of the burner, in the region of the outlet of the primary air into the kiln, by modifying the outlet angle of the radial component for fixed section, thereby greatly simplifying the regulating of the burner.

Abstract: An engine with expansion piston located on the end of a motion arm connected to the engine shaft. On the shaft, rotating compression pistons are mounted. The distance between the two piston types allows for the production of great torque. The geometry of expansion chamber and compression chamber is concentric toroidal. A pressure chamber stores the air-fuel mixture coming from the compression chamber to the expansion chamber and is therefore interposed between the two. The timing of the two or more sliding ports attached to the compression chambers determines the compression volume, while the valves control the communication of the pressure chamber with the other chambers.

Abstract: A rotary internal combustion engine has a hollow stator with inner surface formed by two concentric cylindrical surfaces, which fluently transit one into the other via ramp surfaces, and a cylindrical rotor, having the same radius as smaller concentric surface of the stator. The rotor has vanes that move radially within the rotor tightly contouring the inner surface of the stator during rotor rotation. The cavities within the stator where its inner radius equals that of the rotor constitute combustion chambers, which connect to the variable-volume working chambers formed by outer surface of the rotor, inner surface of the stator with bigger radius and the side of the vane via valve-controlled orifices ending in the areas of the stator ramp surfaces. During rotor rotation the vanes provide compression of fuel mixture into combustion chambers and accept the energy of expanding gasses following fuel mixture ignition in the combustion chamber.

Abstract: A rotary internal combustion engine has a double pivot center and allows for efficient communication between a central cylindrical intake/compression chamber and a crescent-shaped expansion chamber. Power packs rotating about the upper pivot location receive compressed gases from the compression chamber located within a flywheel which is positioned to rotate about the lower pivot location. Intake gases are ultimately compressed within the power packs before being ignited and causing a delayed powering of the power packs through the expansion chamber. Intermeshing of the power packs with the flywheel allows for the conversion of the power of the expanding gases acting on the power pack into rotation of the flywheel to power a drive shaft intimately mounted to the flywheel.
