Abstract: Device for rapidly transferring thermal energy from a heat source to a point of arrival at a velocity greater than the convective capacity of the adjacent element, enabling the thermal energy to be converted into electrical energy via a conversion device positioned at the point of arrival, the thermal energy being transferred via a coating composed of one or more nanomaterials with atoms which form an ordered geometrical structure.

Abstract: A machine tool (1) for machining by chip removal, in which a machining head (2) operates while being positioned in a horizontal plane and is mounted on a vertical bed (3) to which it discharges the forces (F) by which it is axially stressed, this vertical bed (3) being connected to a supporting structure (4). The vertical bed (3) is pivoted on the supporting structure (4) and there are interposed between the vertical bed and the supporting structure one or more bars (5) whose axial length (L) can be varied by magnetostriction produced by electric currents whose characteristics are determined continuously by a control device (6) in such a way as to counteract the horizontal movements of the vertical bed (3), thus keeping the machining head (2) fixed with respect to the workpiece (7) which it is machining.

Abstract: In an electric motor having a rotor (2) and, coaxial therewith, a stator (1), both contained in a frame (3), the motor being capable of rotating a member (4) about an axis of rotation coinciding with the axes of the rotor (2) and stator (1), the rotor (2) is connected in rotation to the member (4), is hollow and its interior houses a shaft (5) that supports both it (2) and the member (4), and the frame (3) of the motor is supported by the same shaft (5) and is connected by an attachment (6) to a structure that does not participate in the rotation.

Abstract: A mounting seat (1) for machine-tools allowing coaxial engagement of the shank (2c) of a toolholder member (2) includes internally a cylindrical bush (3) supporting a plurality of ball bearings (4i) arranged without play between the internal surface (1i) of the mounting seat (1) and the external surface (2e) of the shank (2c). The bush (3) is able to perform an axial sliding movement (S) towards the outside of the mounting seat (1) over a length smaller than or equal to the axial length of its zone occupied by the ball bearings (4i), further axial travel thereof being prevented by end-of-travel stop elements (3s, 1r) and the abovementioned bush (3) having, mounted on it, elements able to prevent separation of the ball bearings (4n) when the zone thereof occupied by the latter is located outside of the mounting seat (1).

Abstract: Multiple operator station (1) for machine tools designed in particular for chip removal along several axes, comprises several operator units (3,4,5) suitable for coupling with a tool or a workpiece, these operator units (3,4,5) being fitted on a bearing structure (2) that is curved in shape with the concave part facing downwards, and positioned in such a way that below the zone (6) in which the part is positioned during machining, there are no functional parts of the machine subject to movement of one part in relation to another.
