Abstract:
The invention relates to a pressure vessel (01), comprising a hollow-cylinder-shaped vessel part (04), which is made of a concrete jacket (07) and which is arranged between a vessel head (02) and a vessel base (03). The cylinder axis (06) of the hollow-cylinder-shaped vessel part (04) extends from the vessel head (02) to the vessel base (03) along the axis of the pressure vessel (01). The hollow-cylinder-shaped vessel part (04) encloses a vessel interior (05), which is closed by the vessel head (02) and the vessel base (03). In a cross-section running perpendicularly to the cylinder axis (06), the hollow-cylinder-shaped vessel part (04) has at least three extensions (08), which are distributed evenly over the circumference of the concrete jacket (07) and which extend radially outward away from the cylinder axis (06). The extensions (08) extend at least so far that, at least from the free end (09) of each extension (08), at least the free ends (09) of the two extensions (08) immediately adjacent in the circumferential direction are visible in a straight line beyond the outer surface (10) of the concrete jacket (07). Linear clamping elements (11) are arranged between extensions (08) adjacent in the circumferential direction. The linear clamping elements (11) put the hollow-cylinder-shaped vessel part (04) under a pre-load, which acts in the circumferential direction and against an overpressure in the vessel interior (05) and is directed radially from the outside toward the cylinder axis (06).
Abstract:
An apparatus and method for constructing a cryogenic storage tank (700) having a welded inner tank (702), an outer shell (704) surrounding the welded inner tank (702), a concrete foundation (728) comprising a raised portion (752), a plurality of cellular glass blocks (734) positioned directly on top of the raised portion (752) of the concrete foundation (728), a leveling course of concrete (736) poured on top of the uppermost layer of the plurality of cellular glass blocks (734), and a mounting apparatus (718) affixed to the concrete foundation (728), where the welded inner tank (702) is positioned on top of the leveling course of concrete (736) and the outer shell (704) is affixed to the mounting apparatus (718) at locations around the periphery of the outer shell (704).
Abstract:
The invention relates to a pressure vessel for storing liquid or gaseous media. The pressure vessel (1) comprises a plastic inner vessel (2), at least one neck piece (4) connected thereto as a separate piece, said neck piece being arranged on the vessel neck in the area of the vessel opening (8), and a support casing (3) that at least partially encloses the plastic inner vessel (2) and the neck piece (4). The neck piece (4) is provided with means for accommodating a connection fitting (9). The pressure vessel according to the invention is characterized by an insert (5), which forms at least part of the vessel neck and which forms a sealing seat for the fitting (9) to be inserted into the neck piece (4).
Abstract:
A system and method for dispensing subcooled CO 2 liquid includes a vacuum insulated bulk tank containing a supply of the liquid CO 2 . A pressure builder having an inlet in communication with a bottom portion of the bulk tank and an outlet in communication with a top portion of the bulk tank vaporizes liquid from the bulk tank and delivers the resulting gas to the top portion of the tank so as to pressurize it. A baffle is positioned within the bulk tank. Below the baffle, a refrigeration system is connected to the heat exchanger coil so that a refrigerant fluid is supplied to and received from the heat exchanger coil so that the liquid below the baffle is subcooled and the liquid above the baffle is stratified. A liquid fill line is in communication with the interior of the bulk tank via a fill line opening that is positioned above the baffle. A liquid feed line is in communication with a bottom portion of the interior of the bulk tank so that subcooled liquid may be dispensed.
Abstract:
Protective cover for a container of fluid, particularly for a compressed-gas bottle, comprising a covering body (5, 6) and a ring (3) that forms an assembly interface designed to be placed between a container and the covering body (5, 6), said cover being characterized in that the ring (3) has an opening (13) around its circumference for positioning it on or removing it from a container.
Abstract:
A fuel cell (10) for use with a combustion tool (86) for delivery of a predetermined amount of fuel with each stem actuation is provided and includes a housing (12) defining an open end enclosed by a closure (16). A main valve stem (26) has an outlet (28), disposed in operational relationship to the open end and reciprocating relative to the housing at least between a closed position wherein the stem is relatively extended, and an open position wherein the stem is relatively retracted. A fuel metering valve (25) is located within the housing, associated with the main valve stem, including a fuel metering chamber (38) disposed in close proximity to the closure and configured so that when the stem is in the open position, only a measured amount of fuel is dispensed through the outlet. In a preferred embodiment, the fuel cell housing includes a separate fuel container (22), and the fuel metering valve includes a valve body (34) having a second end opposite the fuel metering chamber located within the container.
