Abstract: A fish recompression tool comprises an elongate body having and internal airtight chamber, an attachment member, a locking member, a piston, and a spring within the airtight chamber that engages the piston. The attachment member may switch between open and closed configurations, such that a fish is attached to the device in the closed configuration. The attachment member configuration is controlled by the locking member, such that a locked configuration corresponds to a closed configuration. The attachment member switches to the open configuration when the piston moves in response to reaching a water depth that results in the external pressure surrounding the airtight chamber being sufficiently greater than the internal pressure within the airtight chamber and the spring force on the piston. In preferred embodiments, a plug attaches to an open ended elongate body and may be moved to set different unlocking requirements (i.e. different release depths).

Abstract: A hydrostatic release mechanism is provided which comprises a sealed housing having an interior volume and a tunnel adapted to receive a tether extending therethrough. A depth sensor is mounted to the sealed housing and has a diaphragm covering an opening between the interior volume and the ambient conditions. A trigger is contained within the sealed housing and is operably connected to the diaphragm and a firing mechanism. The firing mechanism is actuated by movement of the trigger in response to inward movement of the diaphragm when the pressure on the diaphragm exceeds a predetermined force. The firing mechanism includes a piston having a blade which moves in response to the expanding gases from a pyrotechnic cartridge and passes through the tunnel thereby severing the tether extending therethrough.

The device comprises a body having a holding means for securing the body to the link; a releasing means for releasing the link; a pyrotechnic composition for actuating the releasing means; an igniting means for igniting the pyrotechnic composition, the igniting means being activatable by an increase in ambient pressure; and a pressure-sensing means for detecting a change ambient pressure. In one embodiment, the device can include a sliding blade actuatable by a pyrotechnic composition that is ignited by an electrical stimulus activated by an increase in ambient pressure, and the link may be for example, a cable securing an emergency position indicating radio beacon to a watercraft.

Abstract: The application describes a hydrostatic release device, suitable for releasing life-saving equipment carried on a ship or aircraft when the ship or aircraft sinks or ditches in the sea. A change in ambient pressure is detected by a pressure sensor which opens a liquid-filled chamber and thereby releases a hydrostatic pressure behind a reciprocable member. This reciprocable member then allows release of a release means. The release means can comprise a link prevented from longitudinal movement by an abutment and normally constrained against lateral movement by the reciprocable member. Thus removal of the reciprocable member away from the link enables transverse movement of the link clear of the fixed abutment. Such an arrangement provides a particularly simple and inexpensive release means.

Abstract: A hydrostatically releasable coupling assembly for releasably securing a buoyant object to a vessel with a lashing strap. The coupling assembly includes a pair of lashing plates, a cooperative latching mechanism carried by the lashing plates for releasably coupling the lashing plates together and a composite plunger assembly coupled to one of the lashing plates for movement between a release position and a locking position. The plunger assembly has a first diameter portion shaped for release of the latching mechanism for movement from an engaged position to a disengaged position when the plunger assembly is in the release position, and a second diameter portion formed of plastic and shaped to retain the latching mechanism in an engaged position when the plunger assembly is in the locking position.

Abstract: A hydrostatic pressure release for releasing a life raft or the like when a ship sinks has a flexible diaphragm sealing a chamber on one side and exposed externally on its opposite side. A ceramic vent plug is mounted on the diaphragm so that it is protected within the casing of the device. The diaphragm has a resilient plate with an integral sleeve that projects through a collar in a rigid disc mounted on the plate. The plug is retained within the sleeve, in the collar. A rod projecting from the diaphragm extends into one end of an aperture in a slider and locks it in position. When the device is submerged, the diaphragm is deflected and pulls the rod out of the aperture allowing the slider to be released. A button on the slider extends into the other end of the aperture so that when is is depressed it pushes the rod out of the aperture and releases the slider.
