Filed:

Nov 2, 2010

Appl. No.:

12/917594

Inventors:

Charles Ringer - San Diego CA, US

Assignee:

The United States of America, as Represented by the Secretary of the Navy - Washington DC

International Classification:

F16K 17/36

US Classification:

137 812, 405193, 166356, 114312

Abstract:

A pressure equalizer for an underwater vessel can include a pneumatic reservoir and a pressure compensating valve (PCV). The PCV can be in fluid communication with the surrounding underwater environment and the vessel interior, and in selective fluid communication with the reservoir. The PCV can further include a valve body and a valve plug. As the PCV opens, the plug moves within the body to establish a path of fluid communication from the reservoir, through the PCV to the vessel interior, to allow flow of high pressure compressible fluid from the reservoir into the interior to pressurize the vessel interior. As the vessel interior pressure equalizes with the surrounding environment, the plug moves within the body to close the fluid communication path with the reservoir, thereby stopping the flow of compressible fluid into the vessel interior to maintain the equalized pressure.

Abstract:

Sensors, such as optical sensors and other sensors used in an aqueous environment are protected from biological contamination by applying a biocide behind a shutter. The shutter is capable of covering a subject portion of the sensor or surrounding mounting surface adjacent the sensor in at least a semi-sealing manner. A well or reservoir forms a chamber in the shutter that is capable of holding a biocide having a limited water solubility and a low environmental toxicity in the aqueous environment, for example, anhydrous iodine crystals. The reservoir is in communication with the portion of the sensor while positioned against the portion of the sensor or surrounding mounting surface adjacent the sensor.

International Classification:

G02B 6/28

US Classification:

385 24

Abstract:

An optical coupler is used to transmit optical data across a temporary connection. A housing is configured with a transparent interface window and positioned in front of a receiving optical coupler so that optical signals pass through the transparent interface window for reception by receiving optical coupler. The receiving optical coupler has a capability of accepting alignment errors caused by aligning the housing with a mating housing in an aquatic environment. Alignment is achieved via an alignment mechanism that mechanical positions the mating optical coupling components with sufficient alignment accuracy to permit the optical coupler to receive and transmit signals.

Abstract:

A system for supplying hydrogen gas to a lighter-than-air (LTA) vehicle includes a manifold having multiple vessels. Each vessel has a first chamber that is separated from a second chamber by a barrier. A trigger assembly integrated with the barrier allows a liquid to be combined with a reactant and a catalyst in the second chamber to form a chemical reaction to generate hydrogen gas. A pressure relief valve located on each vessel opens to allow the hydrogen gas to exit when a predetermined pressure is reached, and the hydrogen gas is supplied to the LTA vehicle connected to the manifold.
