Abstract: A transparent or translucent modular upstanding seam flange panel unit comprising opposed seam flange panels mounted in metal male and female engagement members designed to interlock and provide an internal gutter for collecting infiltrating water and for accommodating lateral expansion and contraction of the panels as well as a method for erecting an architectural structure for passing sunlight into an interior region of a building using such panel units.

Abstract: The invention comprises a transparent/translucent panel system including two spaced flat panels and a series of elongated, abutting, rotatably mounted transparent/translucent light-controlling members disposed between the panels in which the light-controlling members are at least partially tubular or have annular members along their length to facilitate rotation of the light-controlling members and include a light-blocking surface whereby differently sized light-controlling members may be used and the light-controlling members, when rotated by a simple drive mechanism, can vary the light passing through the panel system from clear to opaque and can effectively block light between adjacent light-controlling members.

Abstract: The invention comprises improvements to transparent/translucent panel systems including two spaced flat panels and a series of elongated, abutting, rotatably mounted transparent/translucent light-controlling members disposed between the panels in which the light-controlling members are at least partially tubular or have annular members along their length to facilitate rotation of the light-controlling members and include a light-blocking surface including improvements to ensure continued efficient operation when the panel systems are subjected to flexure or deflection and possible permanent deformation.

Abstract: An assembly for controlling the passage of radiant energy through a skylight, a roof or a wall including at least two linked control members positioned across the defined region mounted for generally parallel linked movement relative to each other between a closed position and an open position. The control members have a plurality of transmitting areas and blocking areas arranged so that the respective transmitting areas and blocking areas of the control members are aligned when the members are in the closed position and the transmitting areas of the first control member are aligned with the transmitting areas of the second control member when the panels are in the open position. A motorized motion unit may be used for producing relative movement between the control members. The assembly is particularly well-adapted to be used with a series of adjacent dual panel glazing units where assemblies associated with each adjacent dual panel glazing unit are linked to and controlled by a single motion control device.
