Abstract: A double glazing system, including a first sheet of glass, a second sheet of glass, a spacer element including a first surface for coupling with the first sheet of glass and a second surface for coupling with the second sheet of glass, a blind, or a screen, said spacer element made from low thermally conductive material including rubber and/or silicone foam. The spacer element includes support means including a housing made of a substantially “T”-shaped groove made on a surface perpendicular to the first surface and to the second surface. The support means include two lateral sections for guiding said blind, screen or the like having respective substantially “T”-shaped portions and being able to be engaged in said housing, the lateral sections including respective free ends for supporting respective end portions of said blind, screen or the like.

Abstract: Inside a glass-enclosed chamber is a Venetian blind connected to internal elements for operating it, the elements being workable from outside to raise, lower and incline the slats. The raw slats of the blind are obtained by moulding a rolled strip of aluminium alloy hardened by magnesium. The strip has not been lapped in order to maintain a degree of roughness on both surfaces, ready to receive a reflecting layer. Reflective stratification includes a layer of pure aluminium adherent to the body of the slat that serves to fix a reflective type of interferential dielectric multilayer. Average thickness of the layer of sputtered aluminium depends on the diffusivity of reflected radiation required in relation to the maximum height of the peaks of surface roughness on the body of the slats. Useful multilayers increase reflectance to levels averaging over 85% on a wide interval of wavelengths from near infrared to ultraviolet.

Abstract: System for operating a plain blind within a glass-enclosed chamber having a first end fixed to a blind-roller by means of devices that pull on said blind-roller and on the second end of the blind.

Abstract: System for operating a blind in a glass-enclosed chamber the ends of said blind being respectively fitted to a fixed upper box (40) and to a movable box (60), subjected both to a guide device for translation, parallel to itself, when opening and closing said blind by a pair of cords (85, 86) interacting between the fixed (40) and movable (60) boxes and a lower fixed box (50), and also to a pulling device comprising a small box containing permanent magnets fixed to the movable box (60) and a free knob, containing permanent magnets of opposing pole, so that by matching, through a pane of glass, the magnets in said knob with those fixed to the movable box (60), the blind can be opened or closed as desired.

Abstract: A process for the preparation of 1-(3-trifluoromethylphenyl)-propan-2-ol enantiomersthrough enzymatic resolution by a lipase.

Abstract: A process for the resolution of enantiomeric mixtures of a chiral carboxylic acid, including an esterification reaction of the carboxylic acid in an organic solvent, in the presence of a stereoselective hydrolase, characterized in that an orthoester of the formula R1—C(OR2)3, in which R1 is selected from H and C1–C4alkyl and R2 is C1–C8alkyl or —CH2—C6-10aryl, is used as the esterification reactive.

Abstract: Structure (10) for a glass-enclosed chamber (9) formed of a frame (11) consisting of four channel-shaped pieces (15, 16, 17, 18), angular joins (20) and an angular connection (30) and comprising a blind (80) carried by a box (50) inside the glass-enclosed chamber (9) worked by a device with an electric motor, inside said box (50) and electrically connected to an electric socket (60) situated at one end of said box (50), said socket (60) being shaped so as to permit conjunction, due to matching of the top of the box (50) with the upper channel (18) of the frame (11), to an electric plug (38) with pins-terminals (40-42) for connection by electric wiring to a device for electric feed and control outside the glass-enclosed chamber (9), said plug (38) being placed in the angular connection (30) of the frame (15-18), situated at said end of the box (50).
