Abstract: Apparatus for inspecting flexible packages is provided. The apparatus includes an inspection chamber having a closeable opening for the passage of a sample to be examined and associatable with means capable of generating a decrease in the pressure inside the inspection chamber, a programmable electronic processing unit, a measuring unit controlled by the programmable unit for measuring at least one geometric parameter of a sample received in the inspection chamber, and a pressure sensor unit comprising at least one pressure sensor associated with the programmable unit and capable of measuring the pressure inside the inspection chamber. The electronic unit is programmed to determine a variation, if any, of at least one geometric parameter of the sample as a result of pressure variations with the inspection chamber.

Abstract: Anti-seismic isolator for isolating of a structure provided with support feet with respect to a ground subject to vibrations induced for example by an earthquake, said isolator comprising an oscillating element that can be associated with at least one of the supporting feet of said structure and a supporting framework provided with a supporting base adapted to support the isolator with respect to the ground, in which said oscillating element and said supporting framework are associated with each other by means of connecting elements sliding in pairs of substantially parallel arched guides, arranged in at least one out of said oscillating element and said supporting framework, whereby said oscillating element and said supporting framework are mutually oscillating and the mutual oscillation of the oscillating element and of the supporting framework causes the simultaneous mutual sliding thereof along two directions perpendicular to each other.
