Abstract:
A gas cartridge loading mechanism has a sensor member movable toward a collar retaining portion and mounted to undergo pivotal movement between a locked position and an unlocked position, and a stopper configured to prevent movement of the sensor member when the sensor member is disposed in the locked position and to allow movement of the sensor member when the sensor member is disposed in the unlocked position. The sensor member is configured to move in the locked position when a gas cartridge is set with improper orientation, and to move in the unlocked position when the gas cartridge is set with proper orientation.
Abstract:
An embodiment of the invention comprises an apparatus or system for withdrawing a cryogenic liquid from a container wherein the liquid may be drawn from the container independent of the orientation of the container. The apparatus comprises a conduit having a flexible metallic hose portion and a metallic head. The flexible hose portion has a first end in fluid communication with an outlet portal of the container and a second end to which the head is attached.
Abstract:
An apparatus for safely delivering a hazardous fluid substance to a receiving structure includes first and second supply cylinders containing the fluid substance and each supply cylinder having a supply cylinder release port; a high pressure containment vessel having a vessel wall and being sized to receive and safely enclose the first and second supply cylinders; a high pressure first tube extending from each of the first and second supply cylinders, and in fluid communication with the supply cylinder release ports and extending to and being in fluid communication with a vessel port in the vessel wall; and a vessel valve in fluid communication with each of the first tube for controlling delivery of the fluid substance from the first and second supply cylinders and from the vessel.
Abstract:
A system achieving a high density of transported natural gas by compressing it to high pressures typically above 5 MPa to transport the gas in a modified composition that permits a very low compressibility factor at near ambient temperature either above or below. This reduces greatly the size of the cooling systems that are required. In some cases cooling of the compressed gas may be achieved in a simple heat exchanger cooled by air or water. The transport of the gas takes place in self propelled ships or non-self propelled barges fitted with a cargo containment system capable of storing the cargo at high pressures, typically above 5 MPa and usually not above 25 MPa. The transport vessel may carry a store of higher molecular weight gases (c2 through c7) that when mixed with the incoming cargo results in a molecular weight of the mixture of at least 22 and possibly as high as 28 or higher. The store of higher molecular weight cargo may be gained from gases that condense during discharge of the vessel at its destination due to the adiabatic cooling of the cargo during discharge. These liquids may be retained aboard and transported back to the origin. If insufficient quantities of heavy gases are available at the origin they may be loaded at the destination. If required, the composition of the heavy gases transported back to the origin may be changed through partial discharge or partial receipt of additional hydrocarbons or a combination thereof at the destination point.
Abstract:
The present invention relates to a portable gas cylinder safety containment system removably and operably incorporated with a portable, self powered, toxic gas monitoring system, and both removably attached to a delivery cart system, to provide real time monitoring of the delivery cart contents while in transit. This system is designed particularly for the safe transport between storage and work areas of toxic and hazardous gases used in various research, laboratory and production process, such as those in the semiconductor and microcircuit industries.
