Abstract:
This disclosure discusses providing safer and more accessible insulating cold boxes for cryogenic equipment. A cold box of the current invention includes a housing partially extending out of the cold box jacket wherein equipment that may need to be accessed can be located. The housing includes a breakaway barrier between the main cold box and the external housing to allow overpressures to be relieved into the cold box. Cold boxes may contain cryogenic columns, sections of cryogenic columns, distillation columns, mixing columns, storage vessels, pressure vessels, heat exchangers, and combinations thereof. The housing may contain auxiliary elements such as rotating equipment, pumps, turboexpanders, instrument devices, valves, and piping. Placing auxiliary elements in a housing outside the main cold box allows for safer access to cryogenic equipment.
Abstract:
Apparatus and methods for improving the safety and efficiency and decreasing the cost of producing liquid gas, such as liquid oxygen, with a small-scale use liquefaction device, according to various embodiments of the present invention. In one embodiment, liquid oxygen barrier may be added to interface between a cryocooler and a dewar to control rate of liquid oxygen escape upon a tipping of the dewar. A boiloff vessel in fluid communication with the dewar allows expanding gas from a tipped dewar to escape while allowing the liquid to safely settle in the boiloff vessel. A temperature sensing circuit, in proximity with a heat dissipator or cold finger of the cryocooler, is operable to break an electrical power circuit of the cryocooler or cooling fan when a sensed temperature exceeds a predetermined temperature. Oxygen purity of a feed stream of gas may be sensed and/or displayed.
Abstract:
An arrangement and associated method for moving and filling multiple storage containers with pressurized contents. The arrangement includes a movable rack for receiving the multiple containers. The rack includes ground-engaging movable members for permitting the rack and the multiple containers received thereon to be moved. The arrangement includes a fixed filling station that has a plurality of dispensing devices. Each dispensing device is engagable with a storage container to provide the pressurized contents to the containers. The rack and the filling station are arranged such that the rack is movable into proximity with the filling station and the rack is movable away from the filling station. The dispensing devices are arranged within the filling station such that each container is in proximity to a respective device when the rack and the filling station are in proximity. Also, an arrangement and method for moving and filling different types of storage containers.
Abstract:
A pressure container comprising axially extending side walls formed of plastic extending between a top end and a bottom end. A metal top is attached at a top seam in pressure-containing relation to the top end of the side walls, and a metal bottom attached at a bottom seam in pressure-containing relation to the bottom end of the side walls. Optional top and bottom beads are formed in the side walls to aid in sealingly securing the metal top and bottom to the side walls. A method for containing pressurized materials by providing and filling such a pressure container is also shown.
Abstract:
A device for a pipe (10) in a cargo pressure tank of a ship (2), the pipe (10) mainly being used for loading and unloading of fluids, and the open end portion (13) of the pipe (10) being placed immediately above the lower bottom section (14) of the cargo pressure tank (1).
Abstract:
The present invention relates to a spray can and a pressure releasing structure thereof, in which the pressure in the spray can can be easily and quickly released. A spray can 200 comprises a sealed can body 14 for holding a compressed fluid such as cosmetics, paints, or propane gas, a spout path 16 for leading the fluid in the sealed can body 14 to the outside, an opening/closing means 18 for opening and closing the spout path 16, and an open-state maintaining means 202 for maintaining the spout path 16 in its open state.
Abstract:
Abstract of the DisclosureA cryogenic fluid storage/processing system which includes a tank for storing the cryogenic fluid, and a containment wall surrounding the tank and defining an impoundment area. The system further includes a vaporizer for regasification of the cryogenic fluid. Piping discharges the vaporizer heating medium into the impoundment area, and/or routes it beneath the tank to heat the ground beneath the tank. Further, the system provides for all liquid hydrocarbons to be contained within the impoundment area with the pumps inside and the vaporizers mounted on the containment walls.
Abstract:
A system and method for driving a power tool or other implement using pressurized gas delivered from a portable canister, a business method for distributing canisters for use with such a system and method, and a compact distribution block for regulating pressure and delivering fluid from the canister to the tool.
Abstract:
A housing has a vertical separation wall. The vertical separation wall forms a filling chamber on one side. The housing has a horizontal separation wall on the other side. The horizontal separation wall forms a cooling chamber. A quantity of a liquid in the filling chamber has an apertured horizontal plate at about the middle elevation of the filling chamber. A smaller end-user tank is provided on the plate. The level of liquid is sufficient to immerse the lower portion of a smaller end-user tank. An air conditioning system includes a compressor unit located in the cooling chamber. The air conditioning system includes a refrigerant coil in the filling chamber beneath the plate. A large supply tank of gas is laterally displaced from the housing. A supply tube connects the large supply tank with the smaller end-user tank within the housing.
Abstract:
A relatively low pressure inert gas hazard suppression system (20) is provided which is designed to protect a room (22) or the like from the effects of fire or other hazard. The system (20) includes a plurality of pressurized inert gas cylinders (24) each equipped with a valve unit (26); each valve unit (26) is in turn coupled via a conduit (28) to a delivery manifold (30). The respective valve units (26) are operable to deliver gas from the cylinders (24) at a generally constant pressure (usually around 10-100 bar) throughout a substantial portion of the time of gas delivery, to thereby provide effective hazard suppression without the need for expensive high-pressure gas handling and distribution hardware and a reduction in room venting area due to lower room over-pressurization. Each valve unit (26) has a valve body (48) and a shiftable piston-type sealing member (56). Gas pressure from the cylinder (24) and a spring assembly (184) biases the member 56 to the valve open position, this being counterbalanced by gas pressure within equalization and modulation chambers (180, 182) provided in the valve unit (26). When a hazard is detected, the valve units (26) are actuated by draining of gas from the modulation chambers (182), allowing gas flow from the cylinders (24). As gas discharge proceeds, gas flows into and out of the modulation chambers (182) so as to achieve the desired generally constant pressure gas output. Near the end of gas discharge, the spring assembly (184) becomes predominant and holds the valve unit (26) open until all gas is discharged.
