  • Patent number: 9764261
    Abstract: A suction filter for an automatic transmission utilizes two different types of filter media: a coarse filter media and a fine filter media. The two types of media are arranged in series within a housing such that fluid flows through only one of the two filter media. A hinge valve is arranged in series with the coarse media. The hinge valve passively opens in response to a pressure differential. The hinge valve defines a non-zero flow area when in the closed position and an increasing flow area as it opens. The flow restriction associated with the hinge valve permits a larger ratio of coarse media area to fine media, thereby decreasing the flow restriction when the oil is cold without decreasing the clean-up rate in normal operating conditions.

  • Patent number: 9028682
    Abstract: A system and method for efficiently removing hydrogen sulfide from a natural gas feed stream to produce a Stinson Process feed stream and an acid gas stream. A first solvent separates the majority of the carbon dioxide and hydrocarbons from the hydrogen sulfide in the natural gas feed to produce the Stinson feed stream. By removing the majority of the hydrogen sulfide prior to feeding the Stinson Process, a carbon dioxide stream suitable for use in flooding operations may be produced with the Stinson Process. The system and method also increase the concentration of hydrogen sulfide in the acid gas stream, making it suitable for sulfur recovery operations. The system and method are particularly suitable for natural gas feed streams containing 0.5%-20% hydrogen sulfide and at least 20% carbon dioxide. Operation in an anhydrous mode with the addition of nitrogen aids in solvent recovery for recycling.

In another example, operation of the motor is altered based upon the volume of water moved. In addition or alternatively, a target flow rate of water to be moved by the water pump is determined based upon the target volume amount and a time period. In addition or alternatively, a plurality of operations are performed on the water, and a total volume of water moved by the pump is determined. In addition or alternatively, an optimized flow rate value is determined based upon power consumption.

  • Patent number: 8337695
    Abstract: An apparatus, system and method for removing and treating contaminated materials on a bottom of a body of water and introducing growth packets to revitalize the treated bottom of the body of water. The structure may comprise a vessel with an open face. The vessel may be lowered down to the bottom of the body of water with the face facing down. As a result, the vessel and the bottom form an isolated space. The structure may comprise at least one agitating device(s) for stirring up the materials inside the vessel so as to form a mixture containing the sediment materials which in turn contain the contaminants. Multiple at least one pipe(s) may be coupled to the vessel for transporting the mixture out of the vessel for processing (filtering, treating with chemicals, etc.) so as to neutralize or eliminate the contaminants in the mixture. Then, the treated mixture can be returned to the inside of the vessel via the at least one pipe(s).

  • Patent number: 8206579
    Abstract: An aquarium filtration system with enhanced features comprising a continuous flow of filtered and processed water as well as a continuous drain system is herein disclosed. In such a manner, the water is continually changed over time, thus minimizing required emptying and/or cleaning. Additionally the system holds and maintains the desired pH level and water hardness, while controlling ammonia and nitrite levels. A filter on the incoming water line removes chlorine and other chemicals before the water passes onto the aquarium. The system works in conjunction with a conventional automatic water level controller. Automatic check valves control water flow and prevent back flow.

  • Patent number: 8187861
    Abstract: For extracting phosphorous from algae-in a body of water, the algae are deposited into a sealable tank (200) that is then evacuated, thereby rupturing the algal cell walls. The ruptured algae are then moved to a second tank (260), mixed with water and bacterial cultures, and allowed to settle until the lipids rise to the top and the oil-less debris settles to the bottom. The second tank also contains sacrificial (295) and rusted electrodes (320). The phosphorous from the algae combines with the rust. The lipids and debris are then removed. Next, an electrical source (315) causes the rust to be removed from the rusted electrodes and settle. In addition, a phosphorous-rich scum floats to the top. These components are placed in storage containers for later use and the water is returned, thereby reducing its phosphorous content.
