Abstract: A pulling head work station for attaching the lugs of pulling heads to cables, so that the cables may be pulled simultaneously through a conduit. The pulling head work station includes staggered cable receiving jigs, each jig having two clamps to hold a corresponding cable in place during attachment of a pulling lug. A chop saw to cut the cables and a crimper to secure a pulling lug to each stripped end portion of a cable may be slidably mounted to a work surface of the work station. A wire stripper may be removably attached to the work station.

Abstract: A container for shipping transportable materials at cryogenic temperatures including a vessel which opens to the atmosphere and contains a micro-fibrous structure for holding a liquefied gas such as liquid nitrogen in adsorption and capillary suspension. The micro-fibrous structure comprises a core permeable to liquid and gaseous nitrogen and an adsorption matrix composed of randomly oriented inorganic fibers surrounding the core as a homogeneous body in stable confinement.

Abstract: A double walled nonpressurized cryogenic storage container having an elongated neck tube in combination with a closure assembly for the neck tube. The closure assembly includes a neck plug and a neck tube adapter having access means for sensor and fill lines. The neck tube adapter has an outer shell and an inner shell with a multiplicity of radially projecting spacer elements for establishing an annular space between the outer shell and the neck tube. The inner shell is preferably eccentric to the outer shell.
