Abstract:
A pressure vessel comprises a matrix structure extending in three dimensions. The matrix is in generally hydrostatic (triaxial, or three-dimensional) tension when carrying loading induced by pressure of the compressed fluid stored within a series of voids interlinked at their point of contact in the matrix. A fluid impermeable outer covering surrounds, and is contiguously supported by, the matrix. The pressure vessel can assume an irregular shape. Transfer means, including an artery system, is provided for admitting and discharging the fluid. A solid surface component, while in a liquid phase, can be mounted on the matrix and changed to a solid phase, anchoring the component to the matrix with an integral bond.
Abstract:
Pipeline distribution network systems are provided for transporting pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about -123 °C (-190 °F) to about -62 °C (-80 °F). Pipes and other components of the pipeline distribution network systems are constructed from an ultra-high strength, low alloy steel containing less than 9 wt.% nickel and having a tensile strength greater than 830 MPa (120 ksi) and a DBTT lower than about -73 °C (-100 °F) environ.
Abstract:
A device for spherical ship's tanks (1), especially for liquid natural gas, comprising discharge pipes and filling pipes (3, 4 respectively) which extend vertically and centrally in the tank (1). The upper part of the pipes (3, 4) is attached to the tank and they extend down to the bottom (11) of the tank (1), being suspended in the tank, and the bottom part being passed slidably into respective muffs (15), which are permanently connected to the tank bottom (1). Between the pipes (3, 4) there extend cross-members (5, 6), these together with the pipes (3, 4) forming a truss beam.

Abstract:
The bottle (1) consists of two semispherical parts (2, 3) which are fixed to each other and are equipped with a valve (7) in each end. The bottle can have an inner metal lining (9) and a semispherical membrane (5) which drags onto the one part of the lining and is welded in a flange (10) between the two parts of the lining. The metal lining (9) with membrane (5) and end pieces (6) forms a replaceable unit. By sampling the bottle (1) first is filled with a counter pressure medium, for example water, until the membrane (5) is lying tightly to the one half of the bottle. The bottle is then filled with the fluid/gas-sample caused by that the membrane (5) reverses as water is pressed out and the sample flows in. The membrane will reverse until it drags onto the opposite hemisphere, and the bottle thereby is filled with fluid/gas sample.
