Abstract: Filler neck, including a passage extending along a longitudinal axis, at least one permanently magnetic element being arranged annularly around the longitudinal axis, at least in regions, outside the passage and able to generate a permanent magnetic field in the passage, and either at least one ferromagnetic element arranged annularly around the longitudinal axis, at least in regions, outside the passage, the at least one permanently magnetic element and the at least one ferromagnetic element being arranged so as to be adjacent and so as to overlap, at least in regions, viewed in the direction of the longitudinal axis, or the at least one permanently magnetic element having a height, viewed in the direction of the longitudinal axis, that is different from 10 mm, and arranged in the filler neck such that a magnetic field generated by the at least one permanently magnetic element has a maximum attractive force, towards the longitudinal axis, in a specified position in the passage.

Abstract: A multi-abrasive tool is constituted by a support on which abrasive elements are present. Such abrasive elements are arranged in a manner so as to form one or more paths along which the successive abrasive elements have grain size sequentially increasing or decreasing by an arbitrary quantity when passing from on element to the next. Such principle gives rise to abrasive tools with different conformation both for polishing machines and for grindstones. For roto-orbital and planetary polishing machines, and optionally orbital, such support is circular and the grain sequence is circumferential, or radial, or in both directions. A first tool is constituted by contiguous (or non-contiguous) circular rings, that are differently abrasive. A second tool comprises differently abrasive elements arranged along the circular peripheral edge. A third tool comprises differently abrasive elements arranged along a spiral path of 360° starting from the edge.

Abstract: The present invention relates to an electric generation plant (110) of the type without connection to an distributed electric supply network for generating an alternating electric current destined for a plurality of utilities (105) comprising: a first generator (101) fed with fuel of a fossil origin for generating a first alternating electric current in continuous service, i.e.

Abstract: Abrasive tools of the disposable type applicable to many types of equipment to sand materials of various types are provided. In particular, the invention relates to devices using rotating abrasive discs for sanding machines, which include a plurality of flexible abrasive discs open at a radial cut and arranged in an overlapping and staggered configuration such as to define an abrasive, lamellar-like work surface with overlapping flaps, wherein each flap is formed of a protruding portion of an abrasive disc. Methods of making such abrasive tools are also provided.
