  • Patent number: 10495089
    Abstract: A method of operating a refrigeration system having at least three compressors, in which each compressor has an oil sump with oil at an oil level. The method includes separately connecting the oil sumps of the at least three compressors. Each separate connection allows oil flow only between the oil sumps of two of said compressors thereby preventing bypass flow. The method further includes flowing oil between oil sumps of the at least three compressors and along the separate connections to tend to equalize the oil levels among the oil sumps of the at least three compressors.

  • Patent number: 10426875
    Abstract: An apparatus for cleansing wounds, in which wound exudate is removed from a wound bed and selectively cleansed and returned to the wound. The cleansing means removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The associated wound dressing and cleansing means are conformable to the wound, and may have irrigant fluid circulated from a reservoir by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing.

  • Patent number: 10337768
    Abstract: A method for controlling and adjusting the refrigeration capacities of a refrigeration system equipped with a double suction compressor, the refrigeration system including first and second compartments to be refrigerated and including first and second evaporators respectively positioned in the first and second compartments. The double suction compressor is controlled to alternate its compression capacity with high-frequency between first and second refrigerant suction lines respectively associated with the first and second evaporators such that the first and second compartments are simultaneously cooled. The compression capacity of the compressor is applied to the first and second suction lines based upon respective first and second duty cycles that together account for 100 percent of the compression capacity of the compressor. First and second temperature sensors are associated with the first and second compartments and provide temperature values that are used to select the first and second duty cycles.

  • Patent number: 10286345
    Abstract: A fuel filter assembly incorporates a BLDC motor and control circuit configured to operate at a first rotational speed upon startup and switch to a second rotational speed when measured variables indicate that the filter assembly is filled with fuel. The first rotational speed is initiated as a default when power is applied to the control circuit. If the filter assembly has been serviced, it must be primed before resuming normal operation. The first rotational speed is significantly higher than the second rotational speed to reduce the amount of time necessary to prime the filter assembly. The control circuit is arranged to monitor a variable which corresponds to the torque necessary to drive the pump. When the pump is filled with air prior to priming, lower torque is required to drive the pump, which corresponds to lower current draw and power consumption at the BLDC motor.
