Abstract: System for the non invasive control of the tightness condition of apparatus, 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. The system includes (a) a first sub system including a pneumatic chamber, set at a sampling reference pressure, for the pressure control of each one of said n apparatus of each one of said m homogenous series; (b) a second sub system of treatment and feeding of pneumatic fluid to said chamber in order to support and stabilize said reference pressure; and (c) 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.

Abstract: The system for the automatically tuning of multicavity filters of high frequency signals, by means of screws sticking out from the lid of the plate incorporating said cavities, comprises a robotized movement imparting subsystem SUB-1A, a measuring subsystem SUB-2M for the extraction of the transfer characteristic, a subsystem SUB-3C to compare said measured values to reference parameters, a subsystem SUB-4G for the generation of said reference parameters, and a subsystem SUB-5CO enslaved to said SUB-4G and SUB-1.
