Abstract: Devices and methods for stabilizing a tailbuoy attached to a streamer towed during a marine survey are provided. The tailbuoy includes a floating body configured to be connected to the streamer, and a keel attached to the floating body. The keel is configured to stabilize a motion of the tailbuoy along a towing direction while in a working state, and to be switched between the working state in which the keel is partially submerged and a retracted state in which the keel is removed from water.

Abstract: A device which will act efficiently as a float for any article (e.g. keys, mobile telephone, wallet) attached thereto when dropped into water comprises an inflatable bag (14) of substantially waterproof and air impervious material, a container (12) of compressed gas, and trigger means (16,30,32) associated with the container (12) and operable upon immersion of the device in water to open the container (12) and allow gas from the container (14) to inflate the bag (14). The trigger means comprises a valve (16) mounted on the container (12) and connecting the container to the inflatable bag (14), retainer means (30) operative to hold the valve (16) in a closed condition, and water reactive means (32) which, upon contact with water, serves to release the retainer means (30) and allow the valve to open. The water reactive means may comprise a band of material (32), at least part of which is water reactive.

Abstract: Various embodiments relate to beverage accessory devices for use within beverage receptacles. In one exemplary embodiment, a beverage accessory device generally includes a housing having sidewalls defining a cavity therein. A substantially fluid-tight container is within the cavity of the housing. The container includes sidewalls defining a chamber. At least one of the container's sidewalls is spaced apart from at least one of the housing's sidewalls such that a portion of the housing's cavity remains separating the at least one container sidewall from the at least one housing sidewall. At least one electric light source is substantially entirely within the container's chamber. The chamber can also be configured for receiving at least one power source. The at least one electric light source is operable for illuminating at least a portion of a liquid within the beverage receptacle when the beverage accessory device is within the beverage receptacle.

Abstract: A user worn man overboard beacon that provides multiple indication means to alert a ship to an overboard crew person and to assist in locating the crew person. The beacon device is contained in a housing attached to the clothing of the sailor and is activated upon contact with seawater. A battery powers the multiple indicators contained in the housing, which include a high intensity strobe light to provide a visual indication, an x-band radar patch antenna to transmit a radar signal indication that can be detected by the ship's radar system, and an acoustic transducer to project an acoustic signal indication that can be detected by the ship's sonar system.

Abstract: A rescue buoy package for use on a boat for marking the location of a person overboard and for remaining in that location until help can arrive includes an outer cylindrical tube that is mounted within arm's reach of the ship's helm and an inner cylindrical tube that fits into the outer tube and to which a heavily weighted cap is affixed. The cap extends downwardly over the open upper end of the outer tube keeping the contents dry and secure. The contents include an inflatable mast and a vest-type flotation device. The buoy can be packaged in a normal mode in which it must be deployed manually or in a second mode in which deployment is automatic. In the normal mode the buoy is deployed by pulling upwardly on a knob on the cap to remove the inner tube, the mast and the flotation device from the outer tube, and throwing the inner tube and its affixed cap into the water along with the mast and flotation device.

Abstract: The invention pertains to an electric device which can be started by immersion in a liquid by way of two electrodes. It includes a first circuit having two electrodes in series with a first voltage source and the coil of a first relay, for controlling a second circuit having in series a second voltage source, a second relay and the contact of the first relay. The second circuit also is connected to use terminals for an external load, the voltage at the use terminals of the circuit being equal to the sum of the voltages from the first and second voltage sources. The device can be applied to power submersible buoys and to detect the presence of a liquid.
