    摘要： A signal processor is provided comprising one or more signal processor modules configured to: compare signaling containing information about historical data related to the performance of a pump; and provide corresponding signaling containing information about predicted maintenance needs of the pump on a real time basis based at least partly on the signaling compared containing information about the historical data related to the performance of the pump. The one or more signal processor modules may be configured to compare over time the hydraulic power generated by the pump and electric power consumed by a motor driving the pump, including tracking a ratio of hydraulic to electric power. The one or more signal processor modules may be configured to predict maintenance needs based on an algorithm that takes into account a trade-off between the cost of power consumed by a motor driving the pump and the cost associated with the pump maintenance in order to substantially minimize the total cost of operating the pump.

    摘要： An electronic ignition system for a reciprocating engine includes a pre-ignition prevention control sub-system which acts as an independent monitor system to ensure the ignition system can only command a spark plug to fire when the next cylinder to fire is outside its pre-ignition zone. The pre-ignition prevention sub-system is independent from the circuitry which commands the spark plug to fire to ensure a single point failure of the system can not lead to a controller erroneously commanding a spark plug to fire in the pre-ignition prevention sub-system. An advantage of the present invention is the increased safety the pre-ignition prevention sub-system provides to the engine by significantly reducing the likelihood that fuel/air mixture within a cylinder will be ignited prematurely.

    摘要： A synthetic bead for use in mineral separation is described. The synthetic bead has a surface made of or coated with a synthetic material such as a polymer that is naturally hydrophobic or a polymer that is hydrophobically modified. The synthetic bead can be made of glass having a coating or polysiloxane. The synthetic beads can be placed in flotation cell containing a mixture of water, collector molecules, valuable material and unwanted material or in a pipeline where the mixture is transported from one location to another. The collector chemical can be xanthates. The enriched synthetic beads carrying the mineral particles are separated from the unwanted materials in the mixture. The mineral particles are then released from the synthetic beads by means of low pH treatment, ultrasonic agitation, thermal or electromagnetic treatment.

    摘要： Apparatus featuring synthetic bubbles or beads and a flotation stage. The synthetic bubbles or beads are configured with a polymer or polymer-based material functionalized to attach to the valuable material in a mixture to form at least some enriched synthetic bubbles or beads having the valuable material attached thereto, and also configured to be transported through the mixture based at least partly on a characteristic of the synthetic bubbles or beads. The flotation stage has the mixture containing valuable material, and is configured to receive the synthetic bubbles or beads and to provide the at least some enriched synthetic bubbles or beads having the valuable material attached thereto based at least partly the characteristic of the synthetic bubbles or beads.
