Abstract: A deployable structure for use in establishing a reflectarray antenna is provided that includes a flexible reflectarray and a deployment structure that includes an endless pantograph for deploying the flexible reflectarray from a folded, undeployed state towards a deployed state in which the flexible reflectarray is substantially planar. In a particular embodiment, the deployment structure includes a plurality of tapes that engage the endless pantograph and are used to establish a positional relationship between the deployed reflectarray and another component of the reflectarray antenna.

Abstract: An ultrasonic tying tool for installation of a tape about a bundle of elongate articles. The tool includes an ultrasonic horn wherein the welding tip is moveable between a first position for welding of a tape to secure the tensioned loop about the plurality of articles and a second position wherein the welding tip is translated a distance from the first position to effect cutting of the tensioned loop from the stock of tape and to tack weld the loose cut end to the underlying tape of the loop to eliminate any protruding sharp edges. The tool additionally includes a belt drive mechanism for advancing the tape to the jaw assembly and for tensioning the tape following looping of the tape about the outside.

Abstract: A cable tie includes an elongate generally planar strap and a head. The head includes a tapering entrance into a passageway therethrough for inserting the strap and a flexibly hinged locking pawl adjacent the passageway. The head also includes a fixed locking tooth adjacent the entry end of the passageway for engaging the strap after full securing an article or articles to be bundled. The fixed locking tooth of the present invention is desirably positioned to allow unobstructed insertion of the tail through the head. The present invention is able to minimize the stretching of the strap body when adjacent to the locking pawl by providing an edge which frictionally engages the strap body as the strap body egresses from the passageway of the head. Furthermore, the present invention may include a pair of counter-rotatable locking elements positioned to one side of the passageway through the head.

Abstract: A cable tie includes an elongate generally planar strap and a head. The head includes a passageway therethrough for inserting the strap and a flexibly hinged locking pawl adjacent the passageway. The cable tie resists longitudinal deformation of the locking notches when adjacent the locking teeth on the pawl. Side edge-barriers are located along the strap adjacent the head so that the strap may be cut at a location between the side edge-barriers.
