Frozen/chilled fluid for pipelines and for storage facilities
Methods of, and apparatus for, storing and transporting a hazardous fluid, such as a combustible fuel, include methods and means, respectively, for: (a) treating the fluid to reduce its hazardous condition; (b) storing and/or transporting the treated fluid in such a manner that the risk of its hazardous condition remains reduced; (c) thereafter retreating the fluid to restore it to its original hazardous condition so that the fluid may be used in its restored condition. The hazardous fluid may be treated by adding a substance to, or removing a substance from, the fluid, or by changing the state of the fluid. For example, if the fluid is a fuel, it may be treated by cooling it to near or below its freezing temperature to reduce its combustibility, volatility, explosivity and/or ease of ignition.
Valve configured for regulating the flow of fluid between a device and a cooler
A fluid circuit includes a device, a cooler, and a valve. The valve includes a housing, a sealing member, a biasing device, and an actuator. The sealing member moves inside the housing between a first position and a second position. The actuator includes a smart material that is activated when the temperature of a fluid inside the housing exhibiting at least a first temperature, causing the sealing member to move to the second position. The smart material is deactivated when the fluid is a sufficient number of degrees less than the first temperature, causing the sealing member to move to the first position. The fluid flows from the housing to the device and then to the housing when the sealing member is in the first position. The fluid flows from the housing to the cooler and then to the device when the sealing member is in the second position.
Multifunctional restrictive valve
A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.
Lightweight plenum system for spacecraft application
A gas distribution system for use in an enclosed volume wherein the system includes a distribution duct and a first inflatable duct portion in fluid communication with the distribution duct. The system further includes a passageway defining an opening which extends through the passageway, wherein: the opening is in fluid communication with the first inflatable duct portion; the passageway includes a valve with a flapper positioned within the opening of the passageway; and the flapper is moveable in relationship to the opening by way of a bi-metallic temperature sensing member. The system further includes an inflatable enclosure in fluid communication with the opening of the passageway, wherein the inflatable enclosure is configured to define a volume within and separated from the enclosed volume.

Method and apparatus for gas flow control
A method and apparatus for self-calibrating control of gas flow. The gas flow rate is initially set by controlling, to a high degree of precision, the amount of opening of a flow restriction, where the design of the apparatus containing the flow restriction lends itself to achieving high precision. The gas flow rate is then measured by a pressure rate-of-drop upstream of the flow restriction, and the amount of flow restriction opening is adjusted, if need be, to obtain exactly the desired flow.
