Abstract: A cryostat is provided comprising a closed cylindrical vacuum vessel and a helium vessel situated inside the vacuum vessel. The helium vessel has four mounting supports on either circular face of the helium vessel, with two supports on the upper portion and two supports on the lower portion. Eight composite straps are provided with one end of each of four of the straps rotatably mounted to each of the mounting supports on each end face of the helium vessel. The other end of the straps are mounted through a clevis arrangement to the helium vessel. The straps on each face are parallel to the circular end faces of the vacuum vessel and the helium vessel. The straps symmetrically located about the vertical and horizontal axes of the helium vessel. The radial suspension provided does not move the axial centerline of the helium vessel relative to the axial centerline of the vacuum vessel when the temperature of the cryostat varies.

Abstract: An improved heat-insulating support device is disclosed which is capable of supporting a coolant tank to a vacuum vessel in a manner such that when the vacuum tank is subjected to a great external force after the coolant tank has been cooled down to a cryogenic temperature, the coolant tank and hence cryogenic equipment mounted thereon are held in place and prevented from being displaced beyond a prescribed allowable range, without impairing the intended heat-insulating capability thereof.

Abstract: A filament wound pressure vessel or tank includes a thin metal inner liner of 1020 steel wrapped by epoxy-resin-coated fiberglass filament windings. The coefficients of thermal expansion of the windings and the inner liner are approximately equal. The filament windings are clad in a thick layer of polyurethane foam insulation. The foam-insulated cryogenic tanks containing cryogenic fluid are mounted in the front of a refrigerated transport container cooled by the release of the cryogenic fluid coolants thereinto.

Abstract: In a method and system for storing gas, especially an inert gas for elect impulse space drives which use inert gas as a reaction mass, the inert gas is filled into a storage tank in the gaseous and/or liquid state and is then cooled to solidify it into the solid state in which it is then stored. While in the earth's atmosphere, temperature regulation is achieved by means of thermal insulation of the tank and a convective heat exchange between a cryogenic coolant and the inert gas in the tank. While in the vacuum of space, temperature regulation is achieved by means of radiant heat exchange between the tank and deep space. For extracting the gas from the tank, the frozen gas is locally sublimated from the solid to the gaseous state by a controlled localized heat application, whereby the required gas pressure is developed for withdrawing gas from the tank which holds the gas in the solid state, except at a heated outlet area.

Abstract: A refrigeration installation method and system for transportable containers. The refrigeration system comprising at least one refrigeration panel readily attachable to the interior walls of the refrigerated compartment of a truck, rail car, trailer, or shipping container. Each panel includes a heat transfer member that also acts as a protective liner which forms the exterior surface of each panel. The liner protects a layer of insulation, which has its inner surface bonded to the interior surface of the liner, from contact with the goods transported within the refrigerated compartment. The layer of insulation insulates and protects a refrigeration coil which is also affixed to or is made part of the interior surface of the liner. The outer surface of the layer of insulation is placed in contact with the interior walls of the refrigerated compartment.

Abstract: A refrigerated shelf for a food display counter comprising a sheet of metal having an upper surface for supporting chilled food items and a cooling coil at the underside of the shelf, the coil being adapted for the flow of coolant therethrough for cooling the shelf. Heat transfer means in heat-exchange relation with the coil and the underside of the shelf is provided for effecting a substantially uniform temperature condition throughout the upper surface of the shelf.

Abstract: A cold storage apparatus in which a gas in a cold storage chamber is fed to a cold water spraying cyclone to make low temperature, moisture rich gas and this gas is fed to a water droplet removing cyclone to remove water droplets and then the resultant low temperature moisture rich gas is allowed to circulate through the cold storage chamber.This cold storage apparatus enables constant low temperature moisture rich cold storage at an optional temperature, and in which apparatus a stable storage of vegetables, fruits, meats and so on can be attained without producing frost and causing drying thereof.OBJECT OF THE INVENTIONAn object of the present invention is to provide a cold storage apparatus for allowing cold storage at a low temperature in a moisture rich condition absolutely without causing freezing.Another object of the present invention is to provide a cold storage apparatus wherein perishables such as vegetables, fruits, meats and the like can be preserved for a long period at a temperature from 0.5.

Abstract: A method for manufacturing a refrigerating system. According to the method, adhesive is applied either to outer faces of an intermediate insulating body or to inner faces of a pair of outer metal skins which are to engage the outer faces of the insulating body to form a wall structure therewith, or to all of these faces. Evaporator and condenser coils are introduced into grooves of the insulating body at opposed faces thereof so as to directly engage the metal skins. These coils may be introduced either before or after the application of the adhesive. Then after the skins are applied to the assembly of the insulating body and coils, the assembled insulating body, coils, and skins are situated in an evacuated atmosphere for eliminating any air bubbles in the adhesive while tightly pressing the metal skins against the insulating body and coils.

Abstract: A thermal insulation composite includes at least a first metallic skin sheet, and a plurality of non-combustible metallic filaments randomly interlocked to form a wool and affixed to said first skin sheet. A second metallic skin sheet may be affixed to said wool and said first sheet, or the second skin sheet may be a surface of the structure to be insulated. A fluid is present in the interstices of the filaments and in the zone between the skin sheets. Each of the filaments has a significant length to cross-sectional diameter ratio to minimize its thermal conductivity. The filaments also preferably have a circular cross section to minimize the area of contact and hence the heat conducted between adjacent filaments. In this manner, the conductivity of the wool is made primarily dependent upon the thermal conductivity of the fluid in the interstices of the filaments. Heat transmission by radiation is inhibited by providing a plurality of radiation shields interposed between multiple layers of the wool.
