Abstract: An apparatus for marking the location of an article or piece of cargo which has accidentally or intentionally been dropped from a transport vehicle into a body of water. The marking apparatus includes a housing, having a wall portion, movable from a closed position to an open position when a coupler element is decoupled. A tether line and a float are packed within the housing.

Abstract: A low watch circle buoy system (LWCBS) uses global positioning system (GPS) P(Y) code coordinate sensing and transmission to mark its position in wr depths up to 40 feet to a positional accuracy of 3 meters or less. LWCBS maintains this position with a flotation unit on the water's surface that transmits signals representative of its location. A submerged unit is affixed to a surface at the bottom of the body of water and has outwardly reaching extensions that lie adjacent the surface. The extensions are tethered to the flotation unit by lines that are each connected between a distal part of each of the extensions and the flotation unit. A spool on each distal part each deploys and secures one of the lines to maintain the flotation unit substantially vertically above the submerged unit. These tether lines limit the range (watch circle) the flotation unit may traverse on the water.

Abstract: A safety or traffic marker is capable of providing a continuous physical border between two locations. A housing, or one of several adapters, are employed in a conventional traffic cone to dispense an elongated strip of tape therefrom. In one embodiment, the housing is physically incorporated into the interior of the marker, and is adapted for easy insertion and removal of a tape or safety material dispenser. In order to achieve easy insertion of the tape dispenser into the housing, the upper portion of the marker is split into separable sections. Since the marker is fabricated from a deformable material, the upper portion can be manually separated into an opened position for insertion of the tape dispenser therein. Hook and loop fasteners may be used to fasten together the two sections into a closed position. Adapters may also be used in conjunction with conventional traffic markers for creating a continuous physical border between two or more locations.

Abstract: A flotation device for causing an article to float if accidently dropped into water has protection from being triggered unless submerged. The flotation device includes a casing, a compressed gas cartridge, a pierce head biased by compression of a firing spring, at least one trigger, a dissolvable ring, and a balloon. The at least one trigger passes through, respectively, at least one trigger orifice formed in the casing. So long as a chamfered end of the at least one trigger is held by the dissolvable ring in abutment with a chamfered trigger groove in the pierce head, the pierce head is held against the biasing force of the biasing spring. A water control feature is characterized by a rim of an end cap being narrowly spaced from the casing, thereby forming a water passage therebetween. The width of the water passage between the end cap and the casing is such as to allow water to pass therethrough to the dissolvable ring only if under hydrostatic pressure of submergence.

Abstract: A marker for use by boaters to mark spots in a body of water includes a water-tight, hollow cylindrical main body that floats and which serves as a buoy member. The main body is capped at its opposite ends by end caps that are apertured. An elongate hollow tube is positioned within the hollow interior of the cylindrical main body so that it extends between the apertures. A spool member having a preselected length of line coiled thereabout is rotatably mounted atop the upper end cap and line extends from the spool through the interior of the hollow tube to the bottom of the body of water when the marker is in use, there being a weight at the free end of the line. Beads of progressively larger size relative to the free end of the line are secured to the line, each bead being positioned at a preselected length of the line that represents a particular water depth.

Abstract: A debris shedding buoy having a float body with a top and a bottom is provided. The buoy includes a slide rail, adapted for slidable engagement to a mooring line, is attached to the bottom of the float body. The slide rail is located in a generally centered position beneath the float body and is oriented in a first direction. A rudder device is affixed to the float body and adapted to produce a stabilizing force to maintain the float body in a quasi stable orientation with respect to a current direction, with the first direction being generally aligned to the current direction. Debris lodging against the float body overcomes the stabilizing force produced by the rudder device, causing the float body to rotate from the quasi stable orientation to a second orientation to shed the debris whereupon the float body rotates back to the quasi stable orientation.

Abstract: A small, lightweight, reusable marker buoy is provided for marking a selected location on a body of water. The marker buoy has a buoyant float formed with an upwardly open well within which is mounted a rotatable anchor line spool. A conduit directs anchor line from the spool, through the float body, and out the bottom of the float where it is attached to a weighted anchor. A spring biased friction plate within the well provides resistance to rotation of the spool and a nut that secures the spool on an upwardly projecting spindle can be tightened to press the spool against the friction plate with a predetermined force to provide a preselected resistance to rotation of the spool and thus a preselected tension on the anchor line. In use, the resistance is set to allow the weighted anchor to draw anchor line from the spool as the anchor sinks but to resist further deployment of anchor line from the spool due to wave and wind action after the anchor has fully deployed.

Abstract: A floatation marker is provided for locating and identifying an anchor line. A float provides an interior surface formed as a frustum of a cone. The surface defines a central hole in the float. Preferably, the float provides for a sloped exterior surface so that, with the marker floating in water, the exterior surface is visible from an elevated position. Preferably the float is shaped as a modified torus. A passageway for the anchor line from outside of the float into the central hole of the float is provided so that the anchor line passes through the central hole. A passage block blocks the passage such that the anchor line cannot be passed back through the passage. The passage block may be a sleeve formed so as to fit loosely and slidably around the float so that in one position on the float the sleeve blocks the passage, while in another position on the float the sleeve does not block the passage.

Abstract: A mounting bracket for retaining an EPIRB or similar buoy on a ship comprises a housing with a support frame pivotally mounted in the housing. The lower part of the frame has a peg engaging a recess in the underside of an enlarged central part of the buoy to prevent forward or downward movement. An upper part of the housing overhangs the upper end of the buoy to prevent upward displacement. The frame is pivoted at its lower end and is retained in the housing against the action of a spring by a hydrostatic pressure release. When the mount is submerged, the hydrostatic pressure release allows the spring to displace the frame out of the housing so that the buoy can float free. The frame is in two parts held together by a locking pin so that, when the pin is released, the buoy can be removed without releasing the hydrostatic release mechanism.

Abstract: The Locator Beacon (LB) is an 18 inch diameter hemispherical unit designed to be air dropped via parachute from a search aircraft near an aircraft crash site. The LB is self uprighting when it lands on the ground and its antenna is always oriented for maximum efficiency. When activated, the LB sends out a radio frequency signal on 121.6 Mhz and 243.2 Mhz, this signal can be tracked by aircraft or by ground parties equipped with directional locating equipment. The LB also contains a strobe light beacon to aid in visual acquisition of the unit. The LB remains in the active (broadcast) mode for approximately 20 minutes before resetting itself to the listening mode. External VHF activation of the LB repeats the LB broadcast and strobe light cycle for another 20 minutes.
