Patent ID: 7726178

Claim:
System for the non invasive control of the tightness condition of apparatus and/or relative containers, in particular of the constancy of said condition of m homogenous series, each one of n apparatus, which in the absence of said pressure constancy would have not acceptable, not uniform characteristics and performances, especially of electronic mechanical, hydraulic and similar, apparatus, comprising: a first sub system comprising a pneumatic chamber, set at a sampling reference pressure, for the pressure control of the n apparatus of each of the m homogenous series, wherein the first sub system includes: a pneumatic chamber closed at its distal end and open at its proximal end, the proximal end of the chamber being provided with hooks; means for cadenced mechanized or robotized insertion of said n apparatus of each one of said m series in said chamber; and means for the tight closure of said chamber after each insertion of an apparatus “on duty” comprising a door provided with an external handle on a drummed double wall, within which shear pins and door latches are disposed which, under the action of said handle, engage solidly with said hooks; a second sub system of treatment and feeding of pneumatic fluid (generally compressed air) to the chamber of said first sub system in order to support and stabilize said reference pressure; and a third sub system of comparison and detection of undesired deviations over said reference pressure, of the detected pressure in the chamber occupied, on turn, by each one of the n apparatus of each of the m series; and a platform to support each apparatus, sliding on a rail for the transport of said “on duty” apparatus at the inside of the chamber.
