Abstract: A silhouette illuminating solar powered buoy with a protected illumination source such as a solar lighting unit. The buoy body can be shaped, colored, and formed to various and or necessary buoy standards or regulations. The buoy body has an accessible opening to allow the solar lighting unit to be placed in a manor which allows it to internally illuminate the buoy body.

Abstract: A Reciprocating Generator Wave Power Buoy consists of a reciprocating generator rigidly attached to the underside of an ocean buoy and creates electric power from the surface ocean swells. The generator coil maintains a stable position beneath the ocean surface while the magnetic field housing reciprocates with the vertical motion of the buoy in response to interaction with swell and waves on the surface of the ocean. Damping plates attached to the generator coil inhibit the motion of the generator coil, thus keeping it in a stable position relative to the motion of the magnetic housing. The magnetic housing focuses the magnetic field through the generator coil and the relative motion between the magnetic housing and generator coil creates an electromotive force in the coil. The design of the generator provides a uniform field of single magnetic orientation throughout the entire stroke of the generator.

Abstract: Disclosed herein is a buoy having a means for self-generating electricity using wave power. The buoy includes a float body floating on the sea, and a lower actuating unit extending though a hole formed at the center portion of the float body in such a way as to be vertically set through the body and rectilinearly reciprocating through the body in a vertical direction due to a difference in a moving velocity between the float body and the actuating body when the body is moved by waves. An electric generator is mounted on the float body and generates electric energy by a rotating force generated by conversion of a vertical reciprocating movement of the lower actuating unit into a rotating movement of a pinion engaging with a rack formed along the upper portion of the actuating unit. An upper support unit is installed on the float body for supporting the lower actuating unit. The buoy also has a lamp indicating a position of the buoy using the electric energy generated by the electric generator.

Abstract: A structure improvement of electric buoy is a buoy composed of a lower body and an upper body.

When buoyancy or lead weight varies and buoy sensitivity is poor, one may properly adjust the button to obtain optimal sensitivity.

Abstract: This nautical buoy is used to monitor the surface projection of a deployed anchor by floating above the anchor. This is accomplished by a connecting tether-line (16) from the buoy to the trip-eye of an anchor (48) attached using a shackle (18). As the anchor is lowered using the vessel's normal ground tackle, the tether-line (16) is deployed by unreeling from the buoy until the anchor rests on the bottom. The tether-line (16) is then secured from further deployment using a tether-line restraining tab (19) and the buoy is tossed overboard so as to float above the deployed anchor. A steady or flashing, light can be affixed to the top of the buoy to identify its location in subdued-light conditions. The buoy can also assist in retrieving an anchor, while aboard the vessel, that has been fouled on bottom vegetation, rocks, and/or other debris. Retrieving the anchor is accomplished by pulling on the tether-line (16), thus applying tensional forces nearly opposite to the frictional forces fouling the anchor.

A pair of conical reflectors is positioned within the housing to reflect the beacon light omnidirectionally.

Abstract: Marine buoy lantern employs a heavily damped two-axis gimbal including an outer gimbal frame supported to the lantern housing by a pair of hinges and an inner gimbal member mounted to the outer gimbal frame by another pair of hinges. The hinges are made of plastic and respond very slowly to a torque applied thereto unlike gimbals employing bearings. The inner gimbal member supports the drum lens, flasher, lampchanger, and counterweights. The hinged gimbal cooperates with the counterweights immersed in a very viscous fluid to maintain the lantern vertically disposed notwithstanding angles of inclination of .+-.9.degree., or a total of 18.degree., of the marine buoy mounting the lantern atop thereof.

Abstract: The battery operated signal device employs a gravity operated switching system with a time delay. The time delay is effected in one embodiment by having a weighted element move through a tortuous path when the signal device is thrown into the water before activating the contacts of a switch to energize a circuit. In other embodiments, the time delay is effected by pendular members which pivot when the signal device is inverted to either actuate a switch or to permit passage of a ball to actuate the switch. The time delay extends the time required to turn on the light so that forces developed on the light by the pitching, plunging and rolling action of a vessel do not result in intermittent unwanted operation.
