  • Patent number: 8040091
    Abstract: Stall detection apparatus for an electric motor controller has an input for receiving a drive error flag indicating if the controller is unable to achieve the required motor velocity and an input for receiving a signal in order to measure, directly or indirectly, the actual motor velocity. The actual motor velocity is determined in order to indicate whether the motor is stationary and, only if so, a stall signal is outputted in order to indicate that said motor has stalled.

  • Patent number: 8011412
    Abstract: An apparatus for protecting the exterior or polished surface of wheels as tires are removed and placed on the wheel. The apparatus includes a substantially flat base having a plurality of stanchions extending out from the base. Each stanchion has a collar positioned adjacent to the base that includes a diameter greater than the stanchion. The stanchions are sized to fit through the bolt holes of the wheel in order to generally align each stanchion with one of those holes. Each collar is sized to be preferably slightly larger than the average bolt, or lug, hole on the wheel. Additionally, each collar is sized to cover substantially the same area as the lug nut or nut that normally attaches the wheels to the vehicle upon which they are used.

  • Patent number: 8002996
    Abstract: A self-cleaning discharge system used with a wastewater treatment system. The wastewater treatment system includes a tank for collecting wastewater while the wastewater typically includes solid particles. The discharge system comprises a housing, a filter positioned in the housing, an effluent discharge apparatus positioned inside the filter, and a venturi effect flushing system positioned proximate to the bottom of the housing. The housing includes a perimeter and at least one intake aperture positioned in the perimeter to accept the wastewater. The filter is shaped to substantially restrict flow of particles into the filter and to the discharge apparatus. The discharge apparatus is in fluid communication with the wastewater in the tank and includes a discharge path to position to transport filtered wastewater outside of the tank. The venturi effect system is in fluid communication with the housing and the tank to return the particles restricted by the filter to the tank.

  • Patent number: 7994448
    Abstract: Methods and systems are provided for controlling an automatic separator apparatus of a Materials Recovery Facility. A separator for separating a stream of recyclable paper and containers into a paper stream including primarily paper and a container stream including primarily containers is provided. The separator has at least one adjustable operating parameter. A first detector detects an amount of container contaminants in the paper stream. A second detector detects an amount of paper contaminants in the container stream. A control system operably connected to the separator and the first and second detectors adjust the adjustable operating parameter so as to reduce a combined measure of contaminants in the paper stream and in the container stream.
