`SPECIFICATION
`
`AQUATIC OXYGEN GENERATOR
`
`Tames ANKE w SEN Kru
`
`An oxygen generating device used to extendthe life of fish in bait buckets andlive wells.
`
`The device is placed in a waterfilled bait bucketor live well, and cyclically turns on an
`oxygen evolving anode.
`
`The product consists of the following components:
`
`1. Power Source; (external 12 volt de or internal rechargeable 6 or 9 volt dc)
`2. Anode;Iridium Oxide Coated Titanium or Stainless Steel 1.5" x 1.5" x .0156".
`3. Cathode: Stainless Steel mesh 1/32 spacing
`4. Control/Timingcircuit;
`5. Power management system, in which the Oxygen Button poweris separated from the
`control/timing system. This allows for a predictable operating time. which can be as long as
`96 contiguous hours.
`
`An enclosure which houses the Oxygen Button and the control circuitry.
`
`The main componentof the device is the Oxygen Button.
`
`It consists of:
`
`The Oxygen Evolving Anode consists of a 1.5 x 1.5 x .0156 inch thick titanium
`sheet coated on one side with iridium oxide
`
`The cathode is made of 1/32 inch stainless steel screen mesh
`
`The anode and cathode are separated by a 1/64 inch fiberglass spacer which
`electrically isolates the anode and cathode
`
`Electrical connections are made mechanically to the anode and the cathode the
`above assembly is installed in an enclosure and sealed with epoxy or similar
`potting material to insure the interior of the enclosure does not get contaminated
`with water.
`
`The oxygen button is connected to a power source via a control relay. The coil of
`the relay is connected to a timer control circuit.
`
`The timerdeviceis regulated via a temperature sensing device to determine the on/off ratio
`to regulate the amount of oxygen generated by the device.
`
`Powersources for the timer control circuit and the oxygen button are batteries which
`are connected to a charging circuit which allow for recharging batteries from a
`commercially available power source. Recharge time for the generatoris approximately
`one hour. The run time for the device on a full charge is approximately 96 hours.
