Title: Apparatus for controlling the shape of a flexible spline
Inventor: BERNARDON EDWARD
IPC: D05B39/00
Filed: 1987-05-21
Granted: 1992-01-14
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for controlling the shape of an elongated flexible spline to substantially match a third order polynomial curve extending between first and second end points where the spline extends along a deformable central axis.  A spline support member extends along the central axis. The spline is pivotably coupled to the support member at a first point along said central axis, and is slidingly coupled to the support member at second, third and fourth points along the central axis.  The support member establishes a first predetermined distance (L) along a reference line passing through the interior two of said first, second, third and fourth points, A first spline deflector selectively deflects one of the exterior two of the first, second, third and fourth points by a distance DL in a direction perpendicular to the reference line.  A second spline deflector selectively deflects the other of the exterior two of the first, second, third and fourth points by a distance DR in a direction perpendicular to the reference line.  A controller controls the first and second spline deflectors so that the central axis of the spline is deformed and the intermediate two points substantially match points of the polynomial curve and so that the exterior two points are offset with respect to the reference line and the spline central axis overlies the first and second end points of the curve.

Title: Aluminum plate curtain wall structure
Inventor: TING RAYMOND M L
IPC: E04B2/92
Filed: 1987-05-22
Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a metal plate curtain wall structure.  The joints of the metal plate structure are sealed weathertight without exposed caulking. A second line defense against water infiltration is formed by a concealed internal drainage system without exposed weep holes eliminating the water stain problem under the weep holes and enhancing the archi-tectural appearance.     A plate connection system securely fastened to the stru-ctural support is slidable in the direction parallel to the plate surface allowing free thermal expansion of the plate without weakening the resistance against wind load acting normal to the plate surface.  The connection system is also designed to absorb any conceivable dimensional tolernace of the support frame facilitating the easiness of field erection.
