    Abstract: A fastener adapted to be installed in a hole of a composite structure includes a sleeve, a pin member, and a locking member. The sleeve has an outer surface having an outer diameter. The outer surface of the sleeve is textured. The outer diameter of the tubular portion is less than an inner diameter of the hole of the structure. The pin member has a shank portion. The sleeve is adapted to expand radially over the shank portion of the pin member to form an interference fit between the outer surface of the sleeve and the hole of the structure so as to provide an installed position of the fastener. When the fastener is in the installed position, the texture of the outer surface of the tubular portion deforms to engage with voids of the composite material present on the inner surface of the hole.

    Abstract: A latch having a housing and a latch mechanism located within an interior portion of the housing. The latch mechanism includes an arm, a pair of socket screws, a pair of torsion springs, each of which is connected rotatably to the arm and engages a corresponding one of the pair of socket screws, a bolt mechanism attached rotatably to the housing, and a link attached pivotally to the arm and attached to the bolt mechanism. The socket screws are utilized to adjust loads on the springs. The bolt mechanism is movable between a first position, in which the arm and the link are toggled with one another under the loads of the springs and the bolt mechanism is adapted to engage an external structure, and a second position, in which the link and the arm are untoggled with one another and the bolt mechanism is disengaged with the external structure.

    Abstract: A curtain wall has a plurality of hollow, extruded vertical and horizontal members. The members have a pair of spaced retainer walls which engage a shear block with a pair of tabs that twist locks onto the retainer walls before fastening the block to the member. A second member slips over the block and is fastened by screws. The abutment of the tabs limits rotation of the block and attached member, providing support for a glazing panel attached to the members. The members have longitudinal recesses accommodating wiring that may be covered with a cover. A bracket interacting with the retainer walls like a shear block may also be used.
