Abstract:
A spaced wall container having an inner wall for containment of fuels, cryogenic liquids, and the like spaced from, and connected to, an outer structure by a plurality of tension members to create steady-state stabilizing forces on the outer structure by utilization of the radial and tangential stiffness of the pressurized inner wall. The tension members are spring-biased to ensure tension loading under all conditions. Insulation material is mounted on the tension members between the inner wall and outer structure. Protection against fluid leakage into the insulation material is afforded by a shield interposed between the inner wall and the insulation. The outer structure forms a protective enclosure for the inner wall container in addition to forming the external wall of a Dewar flask when the void between the spaced walls is evacuated.
Abstract:
A pallet suitable for supporting and transporting gas cylinders or like articles includes a baseplate (for supporting the articles) and, on top of this baseplate, a pair of tunnels for receiving the tines of a forklift truck plus a pair of upstanding frameworks at respective opposite sides of the plate, for stabilizing the upper ends of the elongated articles.
Abstract:
A tank for use in storing low temperature liquefied gas having a rigid outer vessel lined with a heat insulating layer and an inner vessel of a thin film construction with gently undulated camber. The peripheral dimensions of the material of the inner vessel are made relatively larger than those of the inner peripheral dimensions of the insulating layer of the outer vessel. The camber serves to relieve the hoop stress acting upon the inner vessel when it is subjected to the load resulting from the low temperature liquefied gas.
Abstract:
A low-temperature liquefied gas storage tank comprising an outer tank made of rigid metals and an inner tank having a thin film construction. The inner tank is provided at its upstanding peripheral inside surface with vertically extending corrugations and includes means for suspending its upper peripheral edge so as to permit contraction and expansion of the inner tank when it is subjected to a liquid load or exposed to a low temperature. The inner tank prevents undesirable cracking and damage thereof and can store the low-temperature liquefied gas in a safe manner.
Abstract:
A LIQUID STORAGE CONTAINER INCLUDES INNER AND OUTER VESSELS SPACED FROM ONE ANOTHER TO DEFINE AN INSULATING SPACE THEREBETWEEN. IN ONE FORM OF THE INVENTION, THE SIDE WALLS OF THE INNER AND OUTER VESSELS EACH HAVE RESILIENT BLANKET MEANS DISPOSED ADJACENT THERETO AND DEFINING A SPACE THEREBETWEEN. THE SPACE BETWEEN THE RESILIENT BLANKET MEANS IS FILLED WITH A MASS OF SUBSTANTIALLY FREEFLOWING LIGHTWEIGHT THERMAL INSULATING MATERIAL. THE ROOF OF THE INNER VESSEL IS SUPPORTED BY SUPPORT MEANS DISPOSED WITHIN THE INNER VESSEL AND EXTENDING VERTICALLY UPWARDLY THEREWITHIN. A ROOF OF THE OUTER VESSEL IN ANOTHER FORM OF THE INVENTION IS SUPPORTED BY SUPPORT MEANS SUPPORTED BY THE ROOF OF THE INNER VESSEL. FURTHER MODIFICATIONS OF THE INVENTIONAL INCLUDE A VESSEL HAVING ONLY ONE SIDE WALL WITH INSULATING MEANS DISPOSED IN SURROUNDING RELATIONSHIP TO THE SIDE WALL AND HELD IN PLACE ADJACENT THE OUTER SURFACE THEREOF.
