  • Patent number: 6591783
    Abstract: A method and apparatus for packaging live fish in sealed containers. A plastic container is partially filled with water, before receipt of fish, with at least some of the air evacuated from the container and replaced with a gas. An air-tight lid is sealed to the container capturing a layer of gas, such as oxygen, in a void over the water. The use of a clear or transparent container and lid, allows the container to operate as a miniature aquarium allowing storage of the fish for an extended period of time. The fish are acclimated to a point-of-use aquarium by weighting of the container for placement in the aquarium. The container includes printed marks for puncture holes to allow the exchange of water between the container and the receiving aquatic environment. The puncture holes permit a predetermined amount of air to escape the container while slowing being displaced by the water of the aquatic environment. The container is designed to sink providing an absolute indicator that fluid admixing is complete.

  • Patent number: 5962164
    Abstract: The instant invention is an electrolyte additive for use with lead acid batteries containing antimony. The electrolyte additive consists of a mixture of natural oil such as white mineral oil or a hydro cracked and treated oil with naphthenic oil, a zinc free rust and oxidation inhibitor and an ethylene-propylene copolymer. The electrolyte additive is placed above the plate cells in lead acid batteries having antimony to inhibit gassing and misting with an ancillary benefit of increasing performance and durability of the battery.

  • Patent number: 5660949
    Abstract: The instant invention is an electrolyte additive for use with lead acid batteries containing antimony. The electrolyte additive consists of a mixture of synthetic oil, naphthenic oil, zinc free rust and oxidation inhibitor and an ethylene-propylene copolymer. So as to allow for faster mixing of the material an anti-foaming agent may be added and the additive is receptive to the addition of dye allowing the consumer to distinguish the additive from a sulfuric acid solution. The electrolyte additive is placed above the plate cells in lead acid batteries having antimony to inhibit gassing and misting with an ancillary benefit of increasing performance and durability of the battery.
