Abstract: The restraining strap has a rectangular cross section with a broad side against cylindrical sections holding a release member. The moment of inertia for a rectangular cross section strap is represented by the formula I=BH3/12. The lower moment of inertia reduces the load on the fusible link.

The actuator has a catch extending between the restrainer and actuator. The catch ends engage the restrainer and actuator and, upon release from the actuator, the catch rotates to allow the restrainer to unwind from about the cylindrical sections.

Abstract: A clamping system for use in a fluid coupling assembly may include redundant locking features for connecting adjacent ends of fluid conduits such as aircraft fuel lines. The exemplary clamping system may make use of two draw latch mechanisms that each separately apply a spring loaded clamping force to a flex band assembly through corresponding draw springs which oppose one another. Thus, either latch mechanism may provide a draw latch function by providing a clamping force to the flex band assembly, which in turn holds the end flanges of the fluid conduits together, thereby providing a sealing connection to facilitate the transfer of a fluid there between. Using two opposed draw latch mechanisms provides for redundant clamping forces such that the failure of one of the mechanisms does not result in an inadvertent disconnection of the fluid conduits one from the other.

The hub structure can be engaged with the inboard end of the striker element so that a rotational movement of the hub structure provides a force on the striker element tending to cause the inboard end to pivot about the pivot structure, deflecting the pivot fulcrum such that the outboard end of the striker element moves in a generally axial direction. The mechanism can be used in a latch.

Abstract: A hook for gripping chain is asymmetrical so that the effective chain length can be adjusted to a part link tightness. The attachment end of the hook is offset from the plane of the hook end, which includes the slot for receiving a link of a chain. If the chain enters from one side of the hook, the chain and hook have a different angle than when the chain enters from the other side of the hook. The resulting change in angle and hence the way the hook interferes with the chain changes the length of chain required for the chain to reach the slot.
