Abstract: A fairing for a tractor-trailer combination to partially enclose a gap between a tractor cab connected to a chassis of a tractor and a tanker trailer having a cylindrical or oval tank. The fairing has a front section conforming to top and side surfaces of the tractor cab, a rear section having a circular element conforming to side surfaces of the cylindrical tank and a central section connecting the front section to the rear section and including an outer lateral surface having a transverse cross-section gradually transitioning between the front section to the rear section. The fairing is designed such that the rear section is sufficiently spaced from the cylindrical tank that the tanker trailer is capable of the articulated movement.

Abstract: A superconducting cable cooling system, wherein coolant continually provides cooling to superconducting cable, comprising a plurality of nodes within a superconducting cable network and a plurality of legs of superconducting cable which interconnect each of the nodes of the superconducting cable network.

Abstract: A cryogenic biological preservation unit having a removable lid and an integrated cryocooler positioned apart from, or within a fixed portion of, the lid and which provides refrigeration to the upper portion of the interior of the unit which also contains a pool of liquid cryogen and at least one biological sample preferably positioned above the pool of liquid cryogen.

Abstract: A method of storing biological samples in which the biological samples are stored in a stack within a vessel interior of an insulated vessel. A pool of liquid cryogen is maintained within the vessel interior by condensing cryogenic vapor boiled off of the pool of liquid cryogen with a cryocooler having a cold finger. The cryocooler and cold finger are positioned so that a cold heat exchanger of the cold finger is in thermal contact with the cryogenic vapor and is positioned above the stack, so as to also maintain a temperature difference within the insulated vessel, between a bottom region of the stack and a top region of the stack, of no greater than about 65K.

Abstract: A cryogenic tank system wherein cryogenic liquid from a primary cryogenic liquid storage tank is subcooled by refrigeration generated by a cryocooler, passed into an auxiliary tank, pressurized, and returned to the primary storage tank, preferably by way of the cryocooler, thus cooling the storage tank contents and reducing the pressure within and the vapor losses from the storage tank.

Abstract: Apparatus for collection and removal of settled solids from the bottom part of a sedimentation zone, comprising a scraper blade attached to a bridge and drawn reciprocatingly and repetitively in a longitudinal path along the sedimentation zone. Means are provided whereby the scraper blade is drawn toward the end walls of the sedimentation zone for transverse alignment therewith at the approach of the bridge to the end walls, so as to eliminate solids accumulation adjacent thereto.
