  • Patent number: 8167525
    Abstract: An unloader for unloading material from a container. In some embodiments, the unloader can include an unloader arm movable within the container, a first chain coupled to the unloader arm and movable to unload material from the container, and a second chain coupled to the unloader arm and positioned to engage material within the container upon movement of the unloader arm. The unloader can have a sensor adapted to transmit signals indicative of a force applied to the unloader arm, the first chain, and/or the second chain. A controller can receive the signal from the sensor, and can alter an operation of the unloader arm, the first chain, and/or the second chain based upon the signal received from the sensor.

  • Patent number: 8075766
    Abstract: A water treatment method is provided for helping to partially or completely remove sodium and methane gas from water. In the method, water is combined with a reactant that is formulated to combine with the sodium in the water and form a compound. The water and compound are then passed through a bed of media for helping to separate the compound from the water. The method also includes aerating the water to release gases contained therein by breaking the water into microdroplets by passing it through a screen. Additionally, the method may include a step wherein the water is passed through an acidic resin for facilitating a cation exchange where additional sodium is removed. A water treatment apparatus for performing the method is also provided.
