Abstract: The electrical outlet safety device is placed between an electrical plug and the corresponding electrical outlet or receptacle to which the plug is connected. The safety device includes a thin body portion formed of a material adapted to expand rapidly if exposed to a predetermined temperature. A series of thin, electrically and thermally conductive blades extends from the body, with the blades being captured between the prongs of the plug and the internal contacts of the receptacle when installed therewith. If excessively high electrical resistance and correspondingly high temperature are produced in one or more of the electrical connections between the plug and the outlet, the blades of the safety device transmit the excessive temperature to the body, whereupon the body is transformed to an expansive electrically insulating foam that expels the plug from the receptacle. Springs may be included within the body to provide additional expansive force.

Abstract: The mobile buoyant aerator has a buoyant toroidal capture tray for capturing contaminants and a large diameter tube extending downward through the center of the tray. The aerator may have air or other gas pumped down through a smaller concentric tube to exit at the bottom of the larger tube to entrain and carry contaminated water up the larger tube, capturing contaminants in the capture tray. Alternatively, the aerator may have a compressed gas tank at the bottom of the larger tube to preclude the need for a smaller diameter tube. In another alternative, the aerator has an air pump at the top of the structure to pump air down through the device. In a further alternative, the aerator has a water pump at the top of the structure that draws water from outside the aerator and pumps the water down through the center to entrain contaminated water.

Abstract: The integrated aeration system utilizes a water pump for aeration. Ambient air/gas is entrained by a circulating water jet induced by the pump. The circulating water jet enters a sealed tank. The entrained gas is broken into bubbles after the impingement between the jet and a receiving pool occurs, aerating the receiving pool by water jet spray. The entrained gas/air builds up headspace pressure above the water pool, the headspace pressure being measured by a pressure gauge. The trapped air above the water pool is released when the headspace pressure increases to reach a desired value to aerate a separate tank/container as a diffused aeration or any other aeration process.

Abstract: The water aeration capsules provide a quick and highly portable system for aerating polluted water. The capsules contain bubbles of air, oxygen, and/or other gas(es) surrounded by a water soluble membrane. The capsules are ballasted to sink. Magnetically attractive ballast elements may be provided, and a magnetic sheet may be placed on the bottom of a smaller body of water to enhance the settling of the capsules. The gas burial disposal capsules may be formed of non-degradable material for substantially permanent gas storage, or of degradable material to allow the gases to slowly permeate the surrounding earth for slow and relatively harmless release. The gas may be pressurized within the capsules to approximately the pressure of the surrounding earth.

Abstract: The water aeration system using a renewable energy source is a self-contained unit having a float and a perforated diffuser plate positioned below the float. An electrically powered air pump is installed atop the structure, and a device for collecting renewable energy also extends above the structure. The renewable energy collection device may be one or more solar panels or a wind generator or wind turbine. The pump draws ambient air in through an inlet and pumps the air down through a supply tube to escape from a nozzle below the diffuser plate. The air then bubbles up through the water, the bubbles being broken up by the small perforations of the diffuser plate to provide efficient aeration of the water. An electrical storage battery and auxiliary power receptacle may be provided to power the pump motor during periods when solar or wind power is not available.

Abstract: The water aerator using a compressed gas container is a self-contained unit having a float and a container of compressed gas (e.g., air, oxygen, etc.) installed beneath a perforated diffuser plate that, in turn, is positioned below the float. High-pressure gas from the container flows through a pipe or tube to a regulator valve and pressure gauge at the top of the pipe. A larger diameter low-pressure pipe or tube is placed concentrically about the high-pressure pipe. Regulated low-pressure gas flows down through the outer low-pressure pipe to a dispensing nozzle below the diffuser plate, whereupon the gas flows upward and is broken up by the perforations in the diffuser plate to form smaller aeration bubbles. An electrical power source, pressure switch, and light may be provided to indicate when the compressed gas container is depleted. The device may be motorized.

Abstract: The encapsulated fire extinguishing agents include a sealed outer shell containing at least one fire extinguishing agent therein. The shell is formed of material that melts when exposed to extreme heat, as in a fire. One embodiment has a single outer shell with a single fire retardant agent therein. Other embodiments may have a second shell within the outer shell, each shell defining an interior volume containing a separate fire extinguishing agent. The agents may combine to form a more effective fire extinguishing agent when the two shells melt. The shells may be formed to melt at different temperatures. Another embodiment includes an outer shell filled with a large number of smaller capsules, each of the smaller capsules filled with a fire extinguishing agent. The smaller capsules may each contain identical agents, or two or more different agents from one another.

Abstract: The water aeration capsules provide a quick and highly portable system for aerating polluted water. The capsules contain bubbles of air, oxygen, and/or other gas(es) surrounded by a water soluble shell or membrane of a suitable substance, e.g., various salts, sugars, water-soluble polymers, such as polyvinyl alcohol. The capsules are ballasted to make their specific gravity greater than the water they displace. The ballast may comprise any non-toxic metal, sand, clay, or other non-organic material, and/or fish bait or other food for aquatic animals. Magnetically attractive ballast elements may be provided, and a magnetic sheet may be placed on the bottom of a smaller body of water to enhance the settling of the capsules. Various means of dispensing the capsules from various mobile carriers are also disclosed, including dispensing by hand from shore or by a diver, from a small boat or larger ship, and/or from aircraft.
