Abstract: A glass laminated structure includes a core of curable flowable material sandwiched between first and second glass panels. A pair of frame members sealed to the panels with an ultraviolet curing adhesive overlap marginal portions of the panels so that an overlapping portion of the core abuts the peripheral edges of the panels to absorb stress and inhibit delamination. The laminating apparatus includes platens with vacuum ports for securing the panels to the platens without excessive panel deformation, recessed portions for proper frame member alignment, and elastomeric seals supplanting the usual vacuum grease. The methodology proceeds by retaining the glass panels and frame members in position using the platens, and sealing the frame members to the panels. Then, the curable flowable material is introduced so that it flows between the frame members to abut the peripheral edges of the glass panels.

Abstract: The following specification discloses the use of a nickel titanium alloy component referred to as Nitinol for purposes of providing a pre-stressed structure. The alloy component provides stiffness to shell structures and tubular members such as oil well pipes, and conduits, as well as pre-stressed loadings for head bolts on engines or other pre-stressed fasteners. Pre-stressing is accomplished by deforming the Nitinol component below its transformation temperature which can be a cryogenic temperature, after which the Nitinol component returns by its memory to a desired shape for pre-stressing. The foregoing develops a large pre-load on a structural joint, so that successful design applications of Nitinol can pre-load joints with minimum load path offset for a shell or other structure. This minimizes in-plane local moments, as well as eccentric loading, and provides joints of lower weight and less internal volume protrusion.

Abstract: A method of making a glass laminated structure comprising retaining first and second glass panels against first and second platens respectively, using differential fluid pressure. The panels are held in spaced, generally parallel relationship and a curable flowable material is introduced into the space between the panels. The flowable material is then cured to provide the glass laminated structure.
