    Abstract: A fastener includes a sleeve, a core bolt, and an insert. The sleeve includes a first portion having a first inner diameter, a second portion having a second inner diameter, and a step intermediate the first and second portions. The core bolt includes a cylindrical portion having a first diameter, a threaded portion having a major diameter, and a thread run-out intermediate the cylindrical and threaded portions. The insert is disposed within the sleeve and is sized and shaped to be retained between the step of the sleeve and the thread run-out of the core bolt when the fastener is in a pre-installation position. The fastener compresses the insert between the step of the sleeve and the thread run-out of the core bolt by an installation motion of the core bolt. The insert deforms away from the core bolt to initiate formation of a bulb in response to the compression.

    Abstract: A fastener installation tool including a cylinder assembly, a handle/sleeve assembly, and a tool head. The handle/sleeve assembly includes a handle having a bore and a sleeve positioned within the bore. An inner wall of the sleeve includes a first portion with a first inner diameter and a second portion with a second inner diameter. The sleeve includes an outer wall having a first portion with a first outer diameter and a second portion with a second outer diameter, the first outer diameter of the first portion of the outer wall of the sleeve being greater than the second outer diameter of the second portion of the outer wall of the sleeve. A space is formed between the second portion of the outer wall of the sleeve and the second portion of the inner wall of the handle, which enables the sleeve to flex during operation of the tool.

    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.

    Abstract translation: 幕墙具有多个中空的，挤压的垂直和水平构件。 这些构件具有一对隔开的保持器壁，其将剪切块与一对突片接合，所述一对突片在将块固定到构件之前将锁扭转到保持器壁上。 第二个构件滑过块，并用螺钉固定。 突片的邻接限制了块和附接构件的旋转，为连接到构件的玻璃板提供支撑。 这些构件具有容纳布线的纵向凹槽，该布线可被盖子覆盖。 也可以使用与保持器壁相互作用的支架，如剪切块。
