Abstract: A hydrogen generator for use with an inner combustion engine or other apparatus, even of a movable type, such as a home gas kitchen, said hydrogen generator comprises a system for separating hydrogen from ammonia, said system comprising a NH3 tank, an ammonia sucking pump, and a cracking oven containing a catalyst, an electric resistance and a H2/N2 separating centrifuge and including a suction device comprising a filter followed by a bottle for providing a feeding volume necessary for the produced hydrogen to compensate for user system requirement variations.

Abstract: In a cat and mouse type apparatus for transforming volume variations of a plurality of chambers into a rotary motion of an axis, all of the driving mechanism is housed in a cylindric cavity coaxial with the driving axis, between the cylindric cavity, a smaller diameter inner coaxial cylinder and two discs perpendicular to the axis, a toroidal cavity in which are housed rotary pistons, each longitudinally traversed by an axis and having a circular sector in cross-section shape, the rotary pistons rotating to form cavities defined therebetween, also having a substantially circular shape in cross section, where the cavities cyclically change their volumes and an apparatus driving shaft is rotatively driven.

Abstract: A reciprocating part free kinematic apparatus, designed for transforming the volume variations of a plurality of chambers into a rotary motion of an axis, is characterized in that all the mechanism for performing this function is housed in a cylindric cavity coaxial with the driving axis, between the cylindric cavity, a smaller diameter inner coaxial cylinder and two discs perpendicular to the axis, being defined a toroidal cavity in which are housed rotary pistons, each longitudinally traversed by an axis and having a cross-section schematically in the shape of a circular sector, said rotary pistons rotating so as to cause the cavities defined therebetween, also of a substantially circular sector shape cross section, to cyclically change their volumes.

Abstract: A variable compression ratio rotating engine comprises a containing cylinder forming variable volume chambers, defined by the cylinder inner wall and piston side walls, the cross-section of which has substantially the shape of a circle sector. During the operation of the engine, the pistons are rotated with an uneven circular motion, by a mechanism including a crank, having an eccentric axis with respect to that of the containing cylinder, and small coupling rods coupling the arms of the crank and the end portions of small shafts passing through the pistons, the compression ratio being changed by means of a further mechanism able of changing the eccentricity value of the crank axis with respect to the cylinder axis.
