Abstract: A high voltage transformer includes a first core and a second core coupled to the first core. The first core includes a protruding portion isolating the second core into a first winding portion and a second winding portion. The first winding portion is wrapped by a first primary winding and a first secondary winding to define a first magnetic circuit, and the second winding portion is wrapped by a second primary winding and a second secondary winding to define a second magnetic circuit. Direction of the first magnetic circuit is reversed to that of the second magnetic circuit. Width of the protruding portion is adjustable to achieve different leakage inductances between the first secondary winding and the second secondary winding, so as to balance current flowing through the first secondary winding and the second secondary winding.

Abstract: A battery cover latching mechanism is provided. The battery cover latching mechanism includes a body member, a battery cover, and a button mounted on the body member. The body member defines a battery receiving space and includes a latching block. The battery cover is placed on the body member to cover the battery receiving space, the battery cover includes a clamp. The button resists the clamp and slides between a first position and a second position. When the button is at a first position, the clamp is released from the latching block. When the button slides from the first position to the second position, the button resists the clamp to move towards the latching block and then latch with the latching block.

Abstract: A circuit that tracks the maximum power point of the solar cell is disclosed in the present invention. Unlikely conventional way of maximum power point tracking (maximum power point is referred to as MPP hereinafter; maximum power point tracking is referred to as MPPT hereinafter) which tracks MPP in the time frame of second or minutes, in the disclosed invention, MPP is tracked within the switching cycle, using the natural current ripple of the downstream converter circuit. The switching cycle is in the order of 10s of micro-seconds. Within the switching cycle of the converter, there is a natural current ripple which will result in the power change. The MPPT circuit tracks the power change and adjusts the current reference value accordingly to operate at MPP of the solar cell.

Abstract: Waste containing sulfur and nickel sulfide is heated to volatilize sulfur and reacted with hydrogen chloride to form nickel chloride.

Abstract: The present invention is for a method of regenerating diluted brine containing hardness from a water softening process. The process includes the steps of contacting the diluted brine with a weak acid ion exchange resin to remove the hardness from the brine and evaporating part of the water from the brine using heat from a production casing gas. The production casing gas comes from a producing oil well of a steam injection secondary oil recovery process. The regenerated brine can then be used to regenerate further quantities of strong acid resin which are used to soften water. The softened water can be used for making steam for use in a steam injection secondary oil recovery process.

Abstract: A settling tank for resolving a mixture of oil, water, and solids from an oil and solids-in-water influent includes two inclined and parallel baffles about which the influent water successively passes. Each baffle preferably has parallel V-shaped grooves in the under surface thereof for entrapping, guiding, and coalescing the oil droplets into large globs for channeling and passing through the openings between the baffles and the tank wall for rising to the surface for draw off. The clear water outlet is positioned on a horizontal plane intermediate horizontal planes through the low forward end of the upper baffle and the high rear end to ensure delivery of an oil-free and solids-free water. An upper oil outlet ensures delivery of a solids-free and water-free oil from the settling tank. A new method for assembling a settling tank is disclosed.

Abstract: A method for resolving a mixture of oil, water and solids including flowing the mixture under and over two forwardly inclined baffles for settling out the solids and for causing oil drops to rise, collect, and flow in V-shaped grooves in the under side of the two baffles for coalescing the drops of oil into larger globs. The final steps of flowing the mixture over the upper forwardly declining baffle left all coalesced oil on the surface for being drawn off as solids-free and water-free oil, and draw off water between the oil outlet and the solids outlet for producing oil-free and solids-free water.
