Abstract:
A mounting bracket assembly includes a clamping arrangement mounted for vertical movement on a mounting structure and is movable between an engaged position and disengaged position relative to a self-contained breathing apparatus held in the mounting bracket assembly. A camming arrangement is located between the clamping arrangement and the mounting structure for permitting and preventing vertical movement of the clamping arrangement relative to the mounting structure. A powered latching mechanism is engageable with a portion of the clamping arrangement for providing unlatched and latched positions. A control arrangement separate from the powered latching mechanism is operatively connected thereto to selectively control the powered latching mechanism and effect release of the self-contained breathing apparatus from the latched position when the vehicle is in a stationary and parked condition.
Abstract:
An integrated ship mounted system for loading a gas stream, separating heavier hydrocarbons, compressing the gas, cooling the gas, mixing the gas with a desiccant, blending it with a liquid carrier or solvent, and then cooling the mix to processing, storage and transportation conditions. After transporting the product to its destination, a hydrocarbon processing train and liquid displacement method is provided to unload the liquid from the pipeline and storage system, separate the liquid carrier, and transfer the gas stream to a storage or transmission system.
Abstract:
A Dewar system is configured to liquefy a flow of fluid, and to store the liquefied fluid. The Dewar system is disposed within a single, portable housing. Disposing the components of the Dewar system within the single housing enables liquefied fluid to be transferred between a heat exchange assembly configured to liquefy fluid and a storage assembly configured to store liquefied fluid in an enhanced manner. In one embodiment, the flow of fluid liquefied and stored by the Dewar system is oxygen (e.g., purified oxygen), nitrogen, and/or some other fluid.
Abstract:
A system and method for dispensing subcooled CO2 liquid includes a vacuum insulated bulk tank containing a supply of the liquid CO2. 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:
Pressure vessel assembly for a pressurized fluid system, comprises an enclosed outer casing, at least one internal tube extending within the casing, at least one fluid accumulator disposed within the at least one internal tube, and at least one cooling passage provided within the at least one internal tube and defined by a clearance between the at least one hydraulic fluid accumulator and the at least one internal tube. The pressure vessel assembly further includes a fluid storage compartment formed between the outer casing and the at least one internal tube. The fluid storage compartment is at least partially filled with a working fluid. The pressurized fluid system also includes a cooling fan allowing forced airflow through the cooling passage for forced cooling of the at least one hydraulic fluid accumulator and the working fluid in the storage compartment of the pressure vessel assembly.
Abstract:
A gas cylinder for the storage of compressed gas includes a shut-off valve in engagement with a mouth of the cylinder; an external pressure sensor device for sensing pressure in the cylinder, the pressure sensor device being in continuous communication with the interior of the cylinder; a temperature sensor device for sensing temperature of the gas in the cylinder, the temperature sensor device being in thermal communication with the interior of the cylinder; a programmable computing device for calculating information from the temperature and pressure signals concerning the amount of contents in the cylinder; and a display screen operatively associated with the programmable computing device for displaying said information.

Abstract:
Fluid storage and dispensing systems, and processes for supplying fluids for use thereof. Various arrangements of fluid storage and dispensing systems are described, involving permutations of the physical sorbent-containing fluid storage and dispensing vessels and internal regulator-equipped fluid storage and dispensing vessels. The systems and processes are applicable to a wide variety of end-use applications, including storage and dispensing of hazardous fluids with enhanced safety. In a specific end-use application, reagent gas is dispensed to a semiconductor manufacturing facility from a large-scale, fixedly positioned fluid storage and dispensing vessel containing physical sorbent holding gas at subatmospheric pressure, with such vessel being refillable from a safe gas source of refill gas, as disclosed herein.
Abstract:
A bundle trailer for containers including (i) a supporting frame on which a plurality of bundles are located; (ii) a plurality of bundles, each bundle comprising: a bundle frame, a plurality of containers containing a chemical, and at least one bundle value for controlling delivery of the chemical in the containers; (iii) at least one trailer valve; and (iv) at least one clamp for fixing the bundle is disclosed. The bundle trailer is capable of delivering high purity hygroscopic, corrosive chemicals, such as elemental fluorine and mixtures thereof, with good flexibility, high safety, and low cost.
Abstract:
The oxygen tank accessory apparatus provides a basket with accompanying hand-operated clamps for affixing the apparatus to an existing supported oxygen tank, such as those attached to vehicles like wheelchairs. The components of the apparatus are made of appropriate materials that meet medical standards and medical environment standards. Both the clamps and the basket are designed to be lightweight. The clamp's opposing convex clamp members, for example, have central cutouts to further save weight. The clamp members are interiorly lined with a frictional material for best tank retention until removal is desirable. The levers with curved extensions provide for a user to easily lever the clamp members away from an oxygen tank so that the apparatus can be easily applied and removed without tools or inordinate physical effort.
