Abstract: This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.

Abstract: A locking mechanism for the folding chassis of electric cutting machines. The chassis (1) comprises: a supporting base (11), a tilting arm (12), and an end arm (13) bearing wheels (14) that are collapsible with respect to a principal arm (10) between a folded and an unfolded position of the chassis. The locking mechanism (2) is installed on the tilting arm (12) and comprises: a locking clip (21) capable of being turned manually between an operative position for the locking of the chassis (1) wherein it is coupled with a number of locking rods (112, 113), and an unlocked position of the chassis (1); a manually displaceable trigger for the retaining of the locking clip in the operational position or the free position; and an elastic element that tends to displace the locking clip (21) and the trigger (22) towards the unlocked position of the chassis (1).

Abstract: The propulsion system for vessels comprises at least one suction sail (3), comprising the suction sail (3) a suction system (10) and a driving unit (8) for driving the rotation of said at least one suction sail (3), in which at least one suction sail (3) also comprises a plurality of sensors (12, 13, 14, 15) connected to a control unit (9), whose control unit determines the operation of the suction system (10) and the transmission unit (8). It permits to provide a propulsion system for vessels that permits to optimize their performance using suction sails.

Abstract: The invention relates to an adjustment device for machines for cutting floor tiles and similar, which is provided with a base (1) and an arm (2) carrying a head with a cutting disc (5), and which comprises an adjustment bolt (3) rotatably mounted on the base and provided with a cam (33) that acts against the inner contour of a square hole (21), the cam (33) having a profile suitable to cause, by means of the rotation of the adjustment bolt (3), the arm (2) to move along a square path (T) and the cutting disc (5) to be adjusted in two directions (x, y), parallel and perpendicular to the longitudinal direction (x) of the base.
