Abstract: The invention relates to improvements to the system for generating energy from the movement of the waves of the sea, according to which, given two consecutive buoys (1i), (1i+1) having respective diameters (di), (di+1) arranged relative to the vessel (2) at a distance (Zi), (Zi+1) respectively, the distances (Zi), (Zi+1) . . . (Zn?1), (Zn) of the buoys (1i) and (1i+1), . . . (1n?1), (1n) relative to the vessel (2), always have a value of Z=k·d, wherein (d) is the diameter of the smallest buoy provided in the distribution, and (k) is a value of no less than one.

Abstract: The invention relates to a system for generating energy from ocean wave movement, comprising at least: one vessel (2) having at least one rotor shaft (3) that acts on an electricity generator; at least one tank (5) which is joined and solidly connected to the vessel (2) and which is full of sea water such that it remains at the water line (f); at least one float (1) joined to the vessel (2) by means of a boom (11); and mechanical means for transmitting the movement of the float (1) to the corresponding rotor shaft (3). In addition, the vessel (2) is attached to a float frame (4). A plurality of vessels (2) can be connected to a float frame (4) and/or a plurality of float frames (4) can be connected to one another. Furthermore, one or more tanks (5) can be attached to said float frames.

Abstract: A marking machine with fixed motors comprising a first electric and fixed motor for transmitting motion to a first head sliding on a first guide in the OX direction, a second electric and fixed motor for transmitting motion to a working head sliding on a second guide in the OY direction; wherein a support is integral with the first head and the second guide; the first and second motors being controlled so as to create a differential motion between the two motors sufficient to effect displacement in the OY direction.
