Abstract: Panel (10) for generating and diffusing heat obtained from a heat-radiating board (30) comprising one or more pieces of electrothermal fabric, with strips of fibreglass laid side by side to form the warp, the weft (50) consisting of a continuous copper wire (51), small in diameter and of considerable length, coated with insulating material, that extends serpentinewise passing alternatively above and below the strips of fibreglass, said board (30) being completed by intermediate and external layers (35, 36) of epoxidic thermoadhesive material and clad on both surfaces with sheets of micanite (31, 32), so that on connecting the ends of the wire (51) forming the weft (50) to a source of electric current, boring holes (65, 66) using means, that may be a laser beam, on the thermoadhesive layer (35, 36) covering the weft (50), this latter converts electric energy into thermal energy.

Abstract: Panel (10) for heating by an electric resistance obtained from a serpentine (55) of highly conductive material formed of a thin continuous strip of constant width, having a high ratio between width and thickness, that generates radiant heat by means of electromagnetic waves, placed inside a flat metal chamber (96) given a hermetic seal by continuous welds (90-95) along all its joins, obtained from a basic rectangular tray-shaped structure (11) and from similarly tray-shaped closing structures (80, 81) placed side by side in the basic structure (11).

Abstract: Process for producing tubular shaped pieces (105) having a rectangular cross section of low height, to transform electric current into diffused heat, by means of pultrusion, with continuous formation, added to known reinforcing materials such as roving (60) and mats (65) of fibreglas, on one broad side of the shaped piece (105), of one or more parallel nets (72, 73) of a weft woven (80, 81) fabric made from a continuous wire (77) of highly conductive material coated with insulating material (78), connected at set intervals to devices (111, 112) of electric sockets incorporated in the plastic material (50) so that, when the shaped piece (105) is cut through at the position of the devices (111, 112) to form electric sockets, and by filling the panels with insulating foam material (145) oblong panels (116) are obtained utilizable for innumerable purpose

Abstract: A system for transforming electrical energy into thermal energy, already diffused has a flat support, and a substantially continuous heat-emitting surface formed by one or more electrically conducting continuous strips, each having a constant thickness, laid flat in parallel lengths and spaced for electrical insulation, the strips being arranged on the flat support and mechanically connected to it.
