ABSTRACT:
A Venetian blind is accommodated within the sealed interspace defined by the two glass surfaces of a glass-box including two or more glass surfaces spaced apart by an aluminum frame which contains the molecular sieve. The Venetian blind is provided with control members which allow adjustment of packing and/or inclination of its blades from outside the glass-box without altering the seal, and therefore the functionality, of the same. Operation from the outside of the control members inside the glass-box is achieved, for each adjustment, by magnetic coupling, through one of the glass surfaces of the glass-box, between a first magnet, positioned inside the glass-box and directly connected to the respective control system, and a second external magnet.
