A separable connector assembly includes a connecting member having a threaded end, and a hollow housing having a cylindrical wall that contains a body rotatably mounted therein. This body is threadably engageable with the threaded end of the connecting member. A first mechanism releasably restrains the body from rotating, and a second mechanism is included for winding a spring about the cylindrical wall of the housing. A third mechanism is included for releasing the spring. A fourth mechanism is included for restraining the threaded end from rotating. A fifth mechanism is included for applying a selected tensile load. When the load is applied, a thread geometry of the connecting member causes the load to be resolved as a torque applied to the body sufficient to cause the body to rotate enabling the connecting member to translate out of engagement with the body and subsequently separate from the body.

In detail, the system includes at least one first pulley mounted on the first structural member and at least one-second pulley mounted on the second structural member. A cable is attached by one end to the first structural member and wound about the first and second pulleys and is attached by its second end to the second structural member. Preferably there are two or more first and second pulleys with the cable alternately wound between said first and second pulleys with one end of cable attached to the first structural member and the opposite end attached to the second structural member. Thus the cable holds the first and second structural members together. A system to sever the cable is included, which upon actuation will sever the cable allowing the two structural members to separate.

An alignment tolerant fastening system for interconnecting first and second members having first and second bores therethrough, respectively, is disclosed. The fastening system may include a fastening member having a shank portion which is receivable within the bores of the first and second members, a nut member for engaging at least a distal portion of the fastener shank portion proximate the second member, and first and second washers, at least one of which includes a plurality of serrations, positionable within the first bore of the first member, about the shank portion of the fastener. More specifically, for purposes of accommodating a misalignment between the first and second bores, the inner wall of the first washer is slidably engagable with the fastener shank portion and the outer wall of the second washer is slidably engagable or interconnectable with the first bore wall which defines the first bore of the first member.

An improved hinge assembly is disclosed that is particularly apt for use with deployable trusses utilized on satellites and other spacecraft. In one arrangement, the inventive hinge assembly comprises a tapered roller bearing assembly having tapered rollers angled towards a hinge axis, and a needle roller thrust bearing assembly positioned radially about at least a portion of the tapered roller bearing assembly to yield a compact and lightweight bearing arrangement, while providing satisfactory radial and axial loading bearing characteristics. An axial preload assembly may also be employed with the roller bearing assemblies in the invention to yield enhanced hinge stiffness and repeatability benefits. Such characteristics are of particular importance with deployable spacecraft truss assemblies for supporting instrumentation during orbit. An additional needle roller bearing assembly may be included at an axially spaced position from the tapered roller bearing assembly to provide overload protection (e. g.

A harmonic traction motor for converting linear motion to rotational motion. A driven shaft is surrounded by the annulus of a shaft driving member having a circumference slightly larger than the circumference of the shaft. At least two actuating devices are connected between the support and the driving member at 90. degree. with respect to each other and sequentially energized to cause the annulus to exert a force around the shaft in a hypocycloidic motion. This motor has high torque, high stiffness, zero backlash and small volume and can be operated in a stepping mode and can be used as a brake or clutch, if desired.

A lock assembly portion may include a housing assembly, first and second latches, at least one latch drive, and at least one actuator. The housing assembly includes a first end portion and an opposite second end portion. The first latch is associated with the first end portion. The second latch is associated with the second end portion. The at least one actuator interfaces the latch drive to the first and second latches. Operation of the latch drive causes the first and second latches to move relative to one another between respective extended and retracted positions.

A locking apparatus for limiting displacement of a fastener relative to first and second members interconnected thereby is disclosed. The locking apparatus may include a locking member which is insertable within a first bore of the first member. In particular, the locking member may have an elastically deformable upper portion and a leg which extend between the fastener and the first member to substantially inhibit displacement (e. g. , rotational) of the fastener relative to the first member.

A connection apparatus utilizes a structural element made of fusible material supported directly in the connection load path of the device. A carrier mechanism is axially translatably supported in the device and utilizes a connecting member to connect two desired structures. The connection mechanism engages and holds the connecting member in a first axial position. In one embodiment, the connection mechanism releases the connecting member when translated to a second axial position. In another embodiment the connection mechanism tensions the connection when translated to the a second axial position. The fusible member is heated to transition from solid to liquid. In the liquid state, the fusible member no longer opposed axial load on the carrier mechanism. The fusible alloy comprises a low melting temperature alloy, such as bismuth-lead or bismuth-tin.

A fastening system for substantially inhibiting slippage between first and second members interconnected thereby is disclosed. The fastening system is particularly useful in instances where at least one of the first and second members is subject to shear loading. The fastening system may include a fastener having a shank portion which is receivable within first and second bores of the first and second members, respectively, and a nose portion of a nut member for engaging a proximal segment of the shank portion of the fastener proximate the second member to substantially inhibit tilting of the fastener relative to the first and/or second member(s).

An improved truss is disclosed that is deployable from a folded, or stowed position to an extended, or deployed position. The truss design facilitates compact storage and is particularly apt for space craft applications. In one aspect of the invention, a truss assembly is provided that includes at least three interconnected truss member sets, each of the truss member sets including first and second truss members that are pivotably interconnected, wherein the truss member sets combinatively define a polygonal structure in the deployed position. The first and second truss members of at least one of the truss member sets are pivotably interconnected to fold inwardly when in the folded position, and the first and second truss members of a second of the truss member sets are pivotably interconnected to fold outwardly when in the folded position. Inboard and outboard supports may be provided at each end of the truss assembly for supportable mounting within a bay of a spacecraft, and for supportably receiving instrumentation and/or additional truss assemblies thereupon, respectively.
