Abstract:
This invention relates generally to an improvement in low pressure storage and dispensing systems for the selective storing of gases having Lewis acidity or basicity, and the subsequent dispensing of said gases at pressures, e.g., generally below 5 psig and typically below atmospheric pressure, by modest heating, pressure reduction or both. The improvement resides in storing the gases in a reversibly reacted state within a reactive liquid having opposing Lewis basicity or acidity.
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.
Abstract:
A compressed-gas tank system has at least two gas vessels, the gas vessels having a base part and a removal part and openings which are assigned to the removal parts. The removal parts of the gas vessels are directly connected to a connecting rail, without any pipelines therebetween. The openings are in communication with a gas passage which runs inside the connecting rail, the connecting rail being assigned a shut-off valve which is common to all the gas vessels. The gas vessels are mechanically connected to a supporting rail, the supporting rail and the connecting rail forming a holding frame for the gas vessels.

Abstract:
An assembly for securing SCUBA gear on a boat without increased use of deck space is provided. A platform is disposed above the deck of a boat. A retainer is disposed above the platform. An opening is disposed within the retainer dimensioned to receive a SCUBA tank therein. The platform may form the upper surface of a cabinet. The cabinet having at least one SCUBA tank supporting member therein. The SCUBA tank supporting member having a radiused surface for securely retaining the SCUBA tank within the cabinet. The support member has a first end and a second end, the first end being higher than the second end.
Abstract:
A high-efficiency liquid oxygen, (LOX) storage/delivery system utilizes a portable LOX/delivery apparatus with a portable LOX container. A portable-unit LOX transfer connector is connected to the portable LOX container and is connectable to a main source of LOX in a primary reservoir LOX container. A portable-unit oxygen gas transfer connector is provided for transferring oxygen gas from the portable LOX container to an oxygen gas delivery device for delivering oxygen gas to a patient. An inter-unit oxygen gas transfer connector also is provided for connecting the portable apparatus to a stationary source of oxygen gas in the primary reservoir container, for transferring oxygen gas to the portable apparatus. A portable-unit primary relief valve is connected to the portable LOX container for venting oxygen gas out of the portable LOX container when pressure in the portable LOX container reaches a predetermined level. When the inter-unit oxygen gas transfer connector of the portable container is connected to the stationary source of oxygen in the primary reservoir container, oxygen gas can be transferred to the oxygen gas delivery device for delivery to the patient from the portable LOX container while oxygen gas is transferred to the portable container from the stationary source of gas in the primary reservoir LOX container.
Abstract:
An apparatus (10) includes a low-carbon steel tube (24). The low-carbon steel tube (24) yields plastically more than about 5% before fracturing at temperatures down to about null40null C. when stress is applied to the low-carbon steel tube sufficient to cause the low carbon steel tube to so yield.
Abstract:
A closure assembly 10 contains positive and/or vacuum pressure within a pressure vessel 16 having a neck 12. A circumferential locking member 22 supported on a door 20 locks the door to the neck, and is radially moveable between an open position and a closed position. A seal 26 between the neck and the door maintains fluid-tight integrity. A lever or other hand powered operator may be used for moving the locking member between the open position and the closed position. The locking member may include locking segments interconnected to form the circumferential locking member.
Abstract:
A pressurized gas supply system includes a pressurized container which expands and contracts. The container includes a one-piece liner molded from a polymer which is reinforced by a high tensile fiber such as KEVLARnull. A valve is molded into the liner, and a regulator is connected to the valve. A hose, having a conserver positioned therealong, extends between the regulator and a fitting allowing a user to inhale gas from the container. The container is carried in a carrying bag, which can be in the form of a carrying case, a purse, or a back-pack.
