Abstract: A desmodromic mechanism having transmission elements connected to and supported by an intermediate element and a primary and a secondary cam both in permanent contact with the transmission elements. The transmission elements, the intermediate element, the primary and secondary cams are assembled to one another to compulsorily move in rotation or linearly relative to one another. The various elements are also assembled in such a way as to form sealed variable volume chambers.

Abstract: It comprises a motor shaft (1); a driven member (5), revolving at different speeds; two reduction members (6, 7) comprising each a series of driving elements (10, 11). The two reduction members (6, 7) are coaxial between themselves and with respect to the motor shaft (1) and it comprises at least one rotor (12) driven by the motor shaft (1) comprising at least three pairs of actuating members (15, 16; 17, 18; 19, 20), one of the actuating members (15, 17, 19) of each pair cooperating with driving elements (10) of one of the reduction members (6), whereas the other actuating member (16, 18, 20) of each pair cooperates with driving elements (11) of the other reduction member (7).

Abstract: An improved six cycle internal combustion engine is provided comprised of an engine block; a crank shaft mounted within said engine block; at least one cylinder within which a piston is slidably mounted and operably connected to said crank shaft; a valve head fixedly attached to said engine block; said valve head, piston and cylinder defining a variable volume chamber; an admission duct adapted to admit air into said variable volume chamber; an exhaust duct adapted to remove exhaust gases from said variable volume chamber; said valve head further including a preheating chamber positioned between and capable of fluid communication with said admission duct and said variable volume chamber and a combustion chamber positioned and said variable volume chamber; said valve head further including (a) at least one admission valve to control the admission of air from said preheating chamber into said variable volume chamber (b) at least one exhaust valve to control the flow of gases from said variable volume chamber in

Abstract: An energy transformation cycle in which the number of strokes is higher than four, at least four of which are:a. the compression of air contained in a variable volume chamber, into a preheating chamber;b. the expansion of the variable volume chamber through the expansion of hot air contained in the preheating chamber;c. the compression of the expanded hot air contained in the variable volume chamber into a combustion chamber where fuel is introduced to cause the combustion of the mixture; andd. the expansion of the variable volume chamber through the expansion in the chamber of high temperature and high pressure combustion gases from the combustion chamber. The engine comprises a body (23) inside which is a movable member (25) defining a variable volume chamber (29). The body (23) comprises an admission duct (35) and an exhaust duct (34).

Abstract: The machine comprises at least one central pivot 7 angularly fast with a control member 1 and mounted for oscillation on said control member 1 around a direction perpendicular to the axis of the control member 1 and a first eccentric 31 the axis of the active portion of which 33 passes through the intersection of the axes of the control member 1 and of the central pivot 7.A piston 22 turns on the active part 33 of the eccentric 31 and is pivoted concentrically to the axis of the central pivot 7. This piston comprises at least one active face 24 moving within at least one chamber 8 to modify its volume. It comprises further cinematic means 37, 38, 41 imposing a relative rotation between the eccentric 31 and the control member 1.The walls 10, 11 of the chamber 8 are fast with the central pivot 7.

Abstract: The device comprises cabins allowing a front or side access, each cabin having a first part and a second part. The first part of the cabin comprises a frame (6), rolling along a rolling track (1,2), carrying a fixed floor (11) surrounded by a fixed protection wall (12). The second part of the cabin comprises a rectangular grooved plate (13). In the loading and unloading areas the plates (13) of adjacent cabins are in contact and form a continuous carpet. A rotary moving door (23) surrounds the cabin when the latter moves individually outside the loading and unloading areas.

Abstract: The invention relates to a mechanical storage installation in which the vertical axis of the elevator shaft orthogonally intersects the axis of the horizontal rolling tracks receiving the series of storage carriages. In this storage the elevator comprises at least a guide structure located outside the horizontal rolling tracks and a mobile device driven reciprocably along this vertical structure, this mobile device carries at least a retractable comb located in its active position inside the rolling tracks and in its inactive position outside of them, and the comb is connected to the mobile device by a single connection, which, during active vertical movements of the comb, traverses the horizontal rolling tracks by passages provided in these latter.

Abstract: A spherical piston machine comprises a chamber whose wall is at least partly spherical. A spherical piston, mounted within this chamber, comprises two elements, the chamber and piston delimiting a free space of variable shape. At least one of the elements of the piston is angularly fixed to a control axle, forming an angle with the longitudinal axis of the machine and extending in a direction passing through the center of the spherical chamber. The two elements of the spherical piston are articulated in a zone extending perpendicular to each control axle. Means are provided for rotatably driving about its own axis at least one of the control axles, as well as for rotatably driving each control axle about the longitudinal axis of the machine.
