Abstract: The centrifugal rotary device for heating and/or vaporizing liquids comprises a casing (1) within which is positioned a truncated conical chamber (12) having an inlet orifice (18) through which a liquid, such as water, to be heated is introduced, and an outlet orifice (19) through which a heated liquid and/or vapor emerges. It comprises a pair of hollow truncated conical rotors (2, 3) positioned coaxially one inside the other, both being inside the truncated conical chamber (12), the inner rotor (3) of this pair being fixed to the end of a first drive shaft (30) passing through an aperture (17) formed in the major base (15) of the truncated conical chamber (12), while an outer rotor (2) of the pair if fixed to the end of a drive shaft (20) passing through an aperture (16) formed in the minor base (14) of the truncated conical chamber (12).

Abstract: The invention relates to a modular system for realising furnishing elements characterised in that it comprised a plurality of different kind of modular elements, each kind of modular element providing at least a base module (10, 20, 30, 40, 50, 60, 70, 80) and an upper cover element (11, 21, 31, 41, 51, 61, 71, 81), said base module (10, 20, 30, 40, 50, 60, 70, 80) being provided above with a fixed joint coupling element, coupling with a corresponding fixed joint coupling element provided under the same base module or the upper cover element, said different king of modular elements providing at least straight modular elements (10; 20), 45° bent modular elements (30; 40), and modular elements with a round fixed joint (70; 80).
