Title: "An Alignment Lever Assembly" Inventor: Francs H.A. Mee An alignment lever is provided for aligning a load item with respect to a target. The alignment lever has a body which has a V-shaped alignment seat. The body is pivotally mounted to displace the seat through an arc of about 45.degree.. A plurality of these alignment levers are used to provide an alignment assembly that is effective for aligning a load item with respect to a target area as the load item moves toward the target area. The alignment levers are located at spaced locations about the perimeter of the target area and serve to provide a target zone which is larger than the target area. An orbital replacement unit is provided which is releasably attachable to a target area of a support structure in which a first electrical connector and nut are mounted in a predetermined spaced relationship. The orbital replacement unit includes a housing in which a threaded shaft is mounted for engagement with the nut. A load transfer mechanism is provided for connecting the shaft to a connector assembly on which a second electrical connector is mounted to mate with the first electrical connector. The mechanism serves to apply a preload at the interface between the orbital replacement unit and the support structure before the electrical connectors are mated. The mechanism also serves to ensure that the electrical connectors can be forcibly separated from one another when the orbital replacement unit is being disconnected from the support structure. |
