20100224622 | RADIANT PANEL OF ANODIZED ALUMINIUM WITH ELECTRIC RESISTANCE OF STAINLESS STEEL - Panel for electric heating has an outer hermetic aluminum shell, an inner shell with a rectangular base and a cover, inside which is an ohmic resistance in the shape of a planar serpentine, formed of a series of U-bends and having two pseudo-circular endings that extend to the inside of a hermetic contact module integrated with the outer shell. The serpentine is made of a rigid bar of stainless AISI 304 steel having a rectangular section, constant width and thickness, and a width-to-thickness ratio of less than 3. Two sheets of mica contact the inner shell and the cover, one on each face of the serpentine, insulate it from the outer shell and minimize the free internal spaces. The base of the inner shell incorporates a thick layer of oxide, black in colour, formed by hard anodizing, favouring infrared irradiation. An internal thermal insulator hinders the flow of heat towards the cover. | 09-09-2010 |

20140020245 | MANUFACTURING OF STACKS OF MULTILAYER PLASTIC LAMINATES FOR PRINTED CIRCUITS - In manufacturing multilayer plastic laminates for printed circuits, a press with two surfaces exerts pressure under vacuum on a stack of laminates, the packs, alternated with separator plates made of anodized aluminum. The packs include prepreg layers. The metalizations present on the two sides of each pack are portions of a copper strip repeatedly folded 180° around each pack and each separator plate. A strong current circulates in the copper strip which heats the strip with resistive behavior: the heat causes the close fixing of the various layers. An auxiliary heater is applied to each surface of the press by element of an interposed insulating plate. This includes an aluminum plate with equidistant longitudinal holes containing the same number of armored candle-like resistors, connected in parallel. A main power supply provides direct current to the copper strip, two secondary power supplies provide alternating current to the two auxiliary heaters. | 01-23-2014 |

20160135304 | MINIATURIZED HEAD FOR INDUCTION WELDING OF PRINTED CIRCUITS - The invention relates to an induction head for welding multilayer stacks for printed circuits and the like, wherein an inductor core associated with an excitation inductance is cooled by air or another gaseous fluid, which circulates in a path provided in the induction head. A second inductor core cooperates with the first one to guide a magnetic flux to at least one junction area of a multilayer stack interposed between the cores: the cooling fluid laps the junction area of the multilayer stack, thus facilitating the detachment of the head at the end of the welding process. | 05-12-2016 |
