Definitions

• Purpose of the above invention is to obtain a system whereby electric energy can be transformed into diffused heat, even at very high temperatures with simple and practical structures avoiding intermediate means of insulation and avoiding the difference between the very high tempera- tures produced and those actually used, as will be explained below
• Subject of the invention are systems and means of electric heating obtained by closing the electric circuit using a band of very thin material, of a thickness measured in microns, highly conductive and wound in the form of a serpentine Inside each bend in the band are metal laminae the external surfaces of which are treated with insulating means
• the band can be continuous or in lengths connected one to another, interrupting the flow of electricity and heat
• the band is preferably of copper though it may also be of aluminium or in any case of some highly conductive material Thickness of the band is advantageously that of 10-20 microns
• the metal laminae placed between one bend in the serpentine and the next can be of steel coated with thermally insulating paint or with some other metal
• Said laminae may be of anodized aluminium on both faces
• Strong metal sheets are laid at the two ends of the panel, said sheets being connected together by suitable mechanical means to create pressure against the various components of said panel and ensure greater structural and thermal compactness
• Said means of pressure and connection may be bolts or their equivalent
• the panel is laid in a strongly made flat box with a strong smooth base and with an upward curving front end In this way the box can be hauled along, for example over weedy ground Haulage can be done by motor-driven means, tractors and the like The ground can thus be cleared of weeds by dragging the box over it
• This method offers all the advantages of speed, simplicity and efficiency
• One or more sets of panels can be placed against the inner sides of ovens Inside these ovens heat is generated at high temperature and diffused for a variety of purposes
• Fig 4 Application of the invented system to an oven, front perspective
• the panel 10 exhibits a copper band 1 1 , bent in the form of a serpentine to form curves 12.
• Brass bars 15, 16 are fixed at the two ends 13, 14.
• terminals 17, 18 for connection by wires 19, 20 to the generator of current 21 .
• Metal laminae 30 are placed between one bend in the copper band and the next, their external surfaces being coated with an anodized layer
• the various bends 12 in the copper band 1 1 warm up generating heat and at the same time diffusing it from the large surface, from the metal laminae 30 and matching sheets 40 41 .
• the combined heat diffused from each band in the serpentine generates directly utilizable heat at a very high temperature.
• Fig 3 the tractor 50, by its linkage means 51 , pulls along the body 60 containing the panel 72 substantially the same as the panel 10 described above.
• the body 60 is joined to the linkage 51 by drawbars 52 articulated on the linkage 51 by the pin 53.
• a cover 61 Over the body 60 is a cover 61 and underneath it is a base 62 joined to the lower plane 65 by an upward curving front 64.
• the electric cable 70 connects the copper band 71 in the panel 72 to the generator of electric current 75 comprising a dynamo 76 driven by the engine of the tractor.
• FIG. 4 shows an oven 90 with door 91 turning on hinges 94 and with internal sides 92, 93 on which panels 95 are placed, substantially the same as the panels 10 already described.
• the ends 97 of the copper band 96 are connected by terminals 98 to a generator of current using wiring 99, 100, 101.
• Heating is regulated and controlled by switch 102 and pilot light 103.
• the high temperatures generated by the opposing heating panels 95 is diffused directly into the oven 105 with maximum efficiency.
