Abstract: A locking device for quickly attaching a wing to and removing the wing from a body of a missile, for example. The locking device is disposed in an opening in the wing and is adapted to secure the wing to the body of the missile using its attachment rail. The locking device comprises a rotatable cam, a rotatable cam follower for locking the wing to the attachment rail, and a cam latch for locking the cam follower in place. The cam has a opening disposed therein that is suitable for accepting a locking tool, such as an Allen wrench, for example, that is used to rotate the cam, and hence the cam follower, to attach the wing to and remove the wing from a m-fissile. A plurality of springs are respectively employed to retract the the cam follower when the locking device is disengaged, and to secure the cam latch in place when the cam follower is locked in place.

Abstract: A quick release mechanical attachment that forms part of a missile loading system for loading a missile onto a launch rail disposed on a vehicle. An electric crane mechanism, comprising a boom and hoist, is used to lift the missile adjacent the launch rail, and the quick release mechanical attachment is used to interface the electric crane to the deck of the vehicle. The quick release mechanical attachment comprises a base that includes a body having an internal bore and a counterbore. An electrical contact arrangement comprising a plurality of insulated conductive members is disposed in the counterbore. A plurality of electrical connectors are coupled to the conductive members, and first securing members are provided for securing the electrical contact arrangement in the counterbore. The base in its assembled condition has a predetermined internal taper. The electrical contact arrangement comprises a plurality of nonconductive spacers that surround the conductive members.

Abstract: A missile loading system for loading a missile onto a missile launcher disposed on a vehicle. The missile comprises fore and aft missile hangers that each have upper and lower hooks that have a predetermined separation distance therebetween. The improvement provided by the present invention comprises a launch rail disposed on the missile launcher that has two cut-outs disposed a predetermined distance apart that equals the separation distance between the fore and aft missile hangers on the missile. A plurality of load detent mechanisms (fore and aft) are provided that each comprise a body having the shape of the launch rail, and a lip by which the missile is secured, and an opening disposed therein. A plurality of holes are disposed in the body that are used to secure the load detent mechanism the cut-outs in the launch rail. A spring-loaded member having the shape of the launch rail is rotatably secured in the opening of the body.

Abstract: In integrated circuits having multiple gate functions, the difference between the propagation delay times of each of the gate functions is often important in that it affects the reliability of the circuits. To determine these delay differences, input signals are applied simultaneously to the multiple gate functions. The output signals of the gate functions are monitored, and a reference signal is generated at the time of sensing the first output signal. This reference signal is indicative of the fastest propagation delay time. A delay time equal to the maximum allowable differential delay time between the fastest propagation delay time and the slowest propagation delay time is added to the reference signal. The delayed reference signal is then compared with the gate function propagation delay time to determine if any of the gate function delays are longer.
