Abstract:
A fluid storage and dispensing system including a fluid storage and dispensing vessel enclosing an interior volume for holding a fluid. The vessel includes a fluid discharge port for discharging fluid from the vessel. A pressure regulating element in the interior volume of the fluid storage and dispensing vessel is arranged to flow fluid therethrough to the fluid discharge port at a set pressure for dispensing thereof. A controller external of the fluid storage and dispensing vessel is arranged to transmit a control input into the vessel to cause the pressure regulating element to change the set pressure of the fluid flowed from the pressure regulating element to the fluid discharge port. By such arrangement, the respective storage and dispensing operations can have differing regulator set point pressures, as for example a subatmospheric pressure set point for storage and a superatmospheric pressure set point for dispensing.
Abstract:
The invention relates to a method in operating a lined cavern provided for the storage of gas coming from a pipeline. During filling of the cavern with gas to a nominal pressure, at least a portion of the gas is withdrawn from the cavern and recirculated to the cavern under cooling and without substantial compression. The method also includes recirculating the gas under heating and without substantial compression.
Abstract:
A canister assembly includes a canister, a plug enclosure, a vent mechanism, a delivery valve mechanism, and a protective handle. The plug enclosure may be attached to the canister at an opening and forms a pressurized seal of the interior cavity of the canister. The vent mechanism automatically reduces pressure when pressure inside the canister exceeds a preset level. The delivery valve mechanism can be automatically and remotely activated subject to a user's control to provide gaseous flow from the canister. The protective handle is fastened to the canister and includes the handle docking element. A docking assembly includes a canister assembly, a manifold assembly, a docking station, and a docking mechanism. The docking mechanism includes a handle docking element and a port docking element. The manifold assembly includes a manifold and at least one port attached to the manifold. The docking station includes a canister bay, protective housing, and the port docking element.
Abstract:
The installation comprises, along a vertical frame (1), locations for gas cylinders, these locations being partially defined by a rack that can be used for transporting the cylinders (7), each location comprising, on the frame, a holding device (9, 10) that can be swung between a lockable closed configuration preventing the insertion or extraction of a cylinder, and an open configuration.
Abstract:
A switchover device for providing a continuous supply of a gas such as chlorine to a water system. The switchover device includes an outlet in communication with a chamber as well as with a vacuum source and two inlets also in communication with the chamber. The switchover device further contains a shuttle that may be positioned to isolate the first inlet, the second inlet, or neither inlet.
Abstract:
A fluid storage and dispensing system including a vessel for holding a fluid, an adjustable set point pressure regulator in the interior volume of the vessel, a dispensing assembly in fluid flow communication with the regulator for dispensing fluid at a pressure determined by the set point of the regulator, and an adjusting assembly exterior to the vessel for in situ adjustment of the set point of the internally disposed regulator. By such arrangement, fluid storage and dispensing operations can have respectively differing regulator set point pressures, as for example a sub-atmospheric pressure set point for storage and a super-atmospheric pressure set point for dispensing.
Abstract:
Apparatus for holding and transporting high pressure rescue air bag system components includes a rigid framework having a base member and a stanchion extending upwardly from the base member. The apparatus incorporates structure which releasably retains the deadman switch, the high pressure regulator and regulator gauge and high pressure air bottle of the system in place for transport by an individual.

Abstract:
A cover for a pressurized fuel tank has at least one heat-reflecting wall surface. Preferably, both sides of the cover wall are heat-reflecting. Preferably, the heat-reflecting property is obtained by metalizing the surfaces, e.g., with mirrored plastic films such as aluminum-coated mylar. Alternatively, the cover wall is made out of a very light (heat-reflective) color. By enclosing the tank within the cover, heat is reflected away from the tank rather than absorbed. While some heat may be transferred to the tank, in general the cover reflects enough heat to prevent a significant number of accidental gas ventings and associated fires. Other features include a slit in the top of the cover through which the fuel line may be fed to the covered tank valve; one or more small air and gas vent holes; and indicia on the inside and outside of the cover for revealing whether the covered tank is full or empty.
Abstract:
A liquid propane reserve system for providing propane to propane operated equipment including a reserve tank interconnected between a main tank and the equipment. Each tank includes a manual shutoff valve so that the main tank may first selectively be depleted of propane after which propane in the reserve tank may then be made available to the equipment without partially refilling the main tank. When the main tank is substantially full by momentarily opening both of the shutoff valves, the reserve tank is quickly refilled and held in reserve until needed by simply closing the second shutoff valve.
