The present disclosure describes a roller blind assembly configured for deployment along a curved window segment. The roller blind assembly including a housing having a hollow body formed with a longitudinal passageway. A guide with a profile being conformable to the curved window segment. The guide having a guide channel and being alignable with the longitudinal passageway. The roller blind assembly including a flexible toothed gear rack to be received within the longitudinal passageway and guide. A drive assembly mountable within the hollow body of the housing; the drive assembly including a motor, a worm operatively connected to the motor and a toothed worm wheel configured to engage the teeth formed on the upper portion of the toothed gear rack to urge lateral displacement of the toothed gear rack relative to the longitudinal passageway and the guide, and a blind attachable to a lower portion of the toothed gear rack.

Auditorium

A structure is provided having two opposing nested pairs of outwardly convex roof arches mounted for rotation about a generally horizontal axis. Each pair of nested roof arches can be rotated about its axis from a lowered nested condition to a raised condition where the inner portion of one arch partially overlaps the other arch of the nested pair. In a preferred arrangement the arches extend between supports on diametrically opposing sides of a stadium building, which has an upper opening. The arches in their raised condition cover the stadium opening and in their lowered condition maintain the stadium substantially open to the elements. The turning moment exerted by the arches is sustained through struts by floats within liquid contained in caissons forming a foundation of the structure. The floats are shaped and guided to follow a path within the liquid as the associated arch rotates such as to substantially balance the turning moment of the latter as they move. A double acting hydraulic cylinder arrangement is connected to the arches at a distance from their horizontal axes to move them between their raised and lowered positions.
