  • Patent number: 6791205
    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.

  • Patent number: 6020653
    Abstract: A submerged reciprocating electric generator is placed below the ocean surface and creates electric power from the surface ocean swells. The generator coil reciprocates linearly in response to an external force acting on a float by passing ocean swells. A cable connects the float on the ocean surface with the reciprocating coil of the submerged generator. A magnetic field is focussed through the coil as it reciprocates, creating an electromotive force in the coil. The magnetic field is created in such a manner as to provide uniform field of a single magnetic orientation throughout the entire length of motion of the reciprocating coil. The generator includes a base formed on the ocean floor supporting magnetic core having a generator coil movably mounted therein and connected to a float with a cable passing through cable alignment bearings. Electromagnetic windings are mounted at the closed end of the generator magnetic flux core.

  • Patent number: 5696413
    Abstract: An electric generator includes a base having an outer pole flux core supported on the base and having a linear bore extending thereinto. A plurality of permanent magnets are mounted to the outer pole along the interior of the linear bore. A center pole flux core extends into the linear bore of the outer pole flux core. A generator coil is formed on the coil support sleeve and slidably mounted over the center pole flux core in the outer pole flux core linear bore and extends from the outer pole linear bore. A float member is attached to the generator coil support sleeve for moving the support sleeve responsive to movement of the float movement whereby the electric generator produces electric power responsive to movement of the float when the float is positioned to float on an oscillated fluid, such as when the electric generator is mounted to a platform over ocean swells.

  • Patent number: 5512253
    Abstract: An irradiator apparatus has a plurality of gamma radiation sources mounted in a housing and includes an ozone generator located in the housing and using the irradiator gamma radiation sources to generate the ozone. A plurality of gamma radiation sources are mounted in the irradiator housing with a gas passageway formed around each source for irradiating air or oxygen passing therearound from a gas input through the housing. A fluid passageway is located inside the irradiator housing and adjacent the plurality of gamma radiation sources for irradiating a liquid passing therethrough. The fluid passageway is connected between a liquid input opening and a liquid output opening through the irradiator housing. The gas passageways connect the ozone generator tubes to the fluid passageway for feeding ozone into the liquid being irradiated so that the irradiator generates ozone and feeds the ozone into the fluid being irradiated.
