Abstract: A multidirectional antiseismic device dissipates mechanical energy and limits loads; it can be used to connect structural sub-systems or insulate at the base entire structures, especially in cases involving significant relative displacements between connected structural sub-systems. The multidirectional dissipating device is essentially constituted by pluralities of metallic elements, especially shaped and arranged in specific configurations. Two of these are "radial" configurations whereas a third type is "annular". In each case, the configurations extend between an abutment and anchoring top construction and an abutment and anchoring bottom construction.

Abstract: The present invention relates to a spheric cap bearing device for safely connecting elements of bridges, viaducts, buildings and the like, which comprises a bottom element, in which there is provided a recess in which is engaged a spheric cap coupling element the bottom of which is slidably supported on the bottom of the recess.At the top of the bottom element there is arranged a top element provided, on the bottom side thereof, with a concave recess mating with the spheric surface of the coupling element.

Abstract: Apparatus for the removal of layers of concrete, particularly from roadways and motorways. This apparatus includes nozzles positioned at one end of respective hollow shafts supported by a ball joint and mounted on movable supports. The said nozzles are supplied with water by means of a high pressure pump upstream of which there are positioned preliminary treatment systems for treating the water itself. The nozzles, moreover, are mounted on a slide controlled by electronic apparatus operable to maintain them at a predetermined height with respect to the surface to be scarified. Means are also provided for the elimination of possible hindrances to the free downflow of the water jets against the surface to be scarified.
