Abstract: A coupon for measuring the corrosion rates of metals in a hostile environment, including two or more thin-film resistive conductors formed on a substrate and positioned in close physical proximity so that they are subjected to essentially the same physical environment. One or more of the thin-film resistive conductors is directly exposed to the potentially corrosive environment while at least one of the thin-film elements is protected from the corrosive nature of the environment. The element or elements that are protected from corrosion are either shielded from the corrosive effects of the environment by the presence of a thermally thin protective layer or by being isolated from the corrosive environment while being maintained at essentially the same temperature as the elements exposed to the corrosive environment. The invention is also directed to a system for measuring the corrosion rate by measuring the change in resistance of the exposed conductor in comparison to the protected chamber.

Abstract: An electrostatic separation apparatus or system is provided for separating a particle mixture into two constituent species. The system includes a distributor for differentially tribocharging the particle species forming the mixture and supplying the charged mixture to a plurality of electrostatic separation cells. Each cell includes at least one separator having an inlet, a separation chamber having an electric field zone for drawing selected charged particles from the particle mixture, a collector, and a transition outlet. The length of the electric field zone is selectively adjustable for varying the charged particle drawing action. A curtain gas flow introduced into the separation chamber carries the selected charged particles drawn from the particle mixture in the electric field zone to the collector. Flow vanes or straighteners are provided for both the particle mixture flow and the curtain gas flow to reduce turbulence in the separation chamber and improve separation efficiency.

Abstract: An electrostatic separation apparatus includes of a plurality of separators is provided for separating a particle mixture into two constituent species. Each separator includes one and preferably a plurality of modular separation stages. Each stage of the separator includes a pair of separation subchambers each having an electric field zone for drawing selected charged particles from the particle mixture. A curtain gas flow is provided for each subchamber to entrain and carry the selected charged particles drawn from the particle mixture in the electric field zone to a collector associated with each subchamber for recovery. The inlets for the particle mixture and curtain gas flows are adapted to straighten and smooth the respective flows to reduce turbulence in the separation subchambers and improve separation efficiency.

Abstract: A triboelectrostatic separation apparatus includes a mixing chamber having opposed first and second charging ports, a separator having a separation chamber, first and second electrodes, and a variable voltage source for applying respective positive and negative voltage potentials to the electrodes. First and second particle streams are delivered through the first and second charging ports resulting in the impingement of the particle streams upon each other within the mixing chamber, thus enhancing the electrostatic charging of the particles contained within the particle streams. The apparatus may also include a pre-separator having a pre-separation chamber, a charged particle collection chamber and a plurality of feed passageways providing fluid communication between the pre-separation and the charged particle collection chambers.
