  • Patent number: 8983667
    Abstract: A system is provided to control fluid flow in a wastewater treatment system through wastewater level manipulation. The wastewater treatment system may include a wastewater treatment plant connected to a plurality of pump stations by a main. Each of the plurality of pump stations may include a wet well with a pump therein. The system may include a central server in communication with a sensor to sense a level of wastewater within the wet well. The pump may be automatically moved to an on position when the level of the wastewater in the wet well is at or above a first level and may be automatically moved to an off position when the level of the wastewater in the respective wet well is at or below a pump cutoff level. The central server may systematically manipulate the first level to selectively set the level of wastewater within the wet well.

  • Publication number: 20150068609
    Abstract: A blanket apparatus for accepting and distributing a pressurized flow of conditioned air into a zone around the body of a bed occupant. The apparatus includes an upper layer and lower layer of differing air permeability, joined to form a flow cavity between them for the pressurized air. A plurality of joining methods between the upper and lower layer is provided within the flow area to prevent the blanket from ballooning under the pressurized air flow. The blanket apparatus contains means to cover an entire bed while directing pressurized conditioned air to specific zones of the bed. The invention also contemplates connection of two independent supplies of conditioned air into a single top layer of bedding under which multiple bed occupants sleep, to evenly distribute such independent supplies into specific dual zone areas. The apparatus achieves its function by utilizing materials that are ordinarily used in existing bed linens and comforters.

  • Publication number: 20150047711
    Abstract: A method supplies a gas, stored in multiple vessels, to a drive assembly of a motor vehicle. Each vessel is assigned a valve for opening and closing the vessel and a gas sensor, in the form of a temperature sensor, for determining a temperature as a state variable of the gas in the vessel. The vessels are connected to the drive assembly via a common line. Along the common line, there is arranged at least one gas sensor, which is common to all of the vessels, for determining at least one state variable of the gas. For the supply to the drive assembly, in each case only one of the valves is opened and all of the other valves are closed. The open valve is closed when at least one determined state variable deviates from a setpoint value by a tolerance value.

  • Patent number: 8955763
    Abstract: A system and method for operating a building heating system. The system includes a controller that operates the heating system in three modes of operation. The controller controls a valve that regulates the flow of steam to the building water loop. By maintaining a constant steam flow rate during peak demand periods, steam consumption during peak demand periods are reduced while maintaining a comfortable environment within the building.

  • Patent number: 8945476
    Abstract: A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.
