Abstract: A high-pressure container includes a liner and a fiber layer formed of reinforcing fibers wound around an outer periphery of the liner. The fiber layer has a plurality of hoop layers in which reinforcing fibers are wound in the circumferential direction of the liner to reinforce the body portion. The reinforcing fibers used for a first hoop layer from an inner peripheral side of the fiber layer or the first hoop layer and one or more hoop layers subsequent to the first hoop layer, among the plurality of hoop layers, have a structure in which a plurality of filaments are twisted so as to be inclined with respect to a fiber bundle direction, and have a property of more easily elongating than the reinforcing fibers used for the hoop layer that is located on an outer peripheral side of the fiber layer.

Abstract: Cladding of the interior of a component part of a pressure vessel is shown. A lining which conforms to at least a portion of the interior geometry of the component is positioned in the interior of the component. The lining is then pressed into the component past its yield strength. The lining is then fused to the component.

Abstract: A fuel transfer station may provide for the refilling of fuel canisters providing fuel to combustion powered equipment. The fuel transfer station may include a base, a frame coupled to the base, a first connection port and a second connection port provided in the base, and fluid flow lines connecting the first connection port and the second connection port. A supply tank may be supported by the frame and detachably connected to the first connection port. A fuel canister to be refilled may be detachably connected to the second connection port. Fuel contained in the supply tank may be selectively supplied to the fuel canister through the fluid flow lines in response to a pressure gradient drawing the fuel into the fuel canister.
