Abstract:
A system and process for reclaiming metals from bottom ash material comprising a pair of rod mills each having an inlet for receiving material and an outlet for discharging material, the outlet of a first rod mill being connected to the inlet of a second rod mill, said rod mills for inclination and power, a circuit for water flow through the rod mills for flushing crushed material and metal from the rod mills to a screen where metal is separated from minerals and water and a processing device for separating minerals from the water of the screen separated minerals and water.
Abstract:
A method of automatically controlling chloramine concentration in a body of water contained in a reservoir includes: (a) determining residual chloramine concentration in a water sample; (b) automatically engaging a supply of chlorine to add chlorine when (i) the residual chloramine concentration in the water sample is determined to be below a predetermined residual chloramine concentration set-point or (ii) below a chloramine concentration percentage of a predetermined residual chloramine concentration set-point; (c) determining residual chloramine concentration in one or more additional water samples after step (b); (d) determining the rate of change in chloramine concentration; and (e) if the rate of change in chloramine concentration is below a set rate of change in chloramine concentration (i) automatically engaging a supply of ammonia and the supply of chlorine to add both ammonia and chlorine to the body of water, or (ii) stopping the supply of chlorine after step (d).

A method of automatically controlling chloramine concentration in a body of water contained in a reservoir includes: (a) determining residual chloramine concentration in a first water sample obtained from the body of water; (b) automatically engaging a supply of chlorine to add chlorine to the body of water when the residual chloramine concentration in the first water sample is determined to be below a residual chloramine concentration set-point or a first chloramine concentration percentage; (c) determining residual chloramine concentration in a second water sample obtained from the body of water after step (b); and (d) automatically engaging a supply of ammonia and the supply of chlorine to add both ammonia and chlorine to the body of water if the residual chloramine concentration in the second water sample is determined to be below the residual chloramine concentration in the first water sample or a second chloramine concentration percentage.
Abstract:
A lift for elevating an object having a base including two legs, lifting apparatus associated with each leg, vertically telescoping guard elements extending along each leg, the lifting apparatus being arranged to lift an object disposed above a plane between said legs, the guard elements telescoping vertically when the lifting apparatus is deployed to exclude a person's limb from a space above said planes.

Abstract:
A shaker table for settling randomly oriented items in a generally rectangular container with sidewalls prone to bulge at lower portions thereof, including a pan with a generally horizontal bottom for supporting the container and an underlying pallet while being shaken, a power drive for shaking the pan, container, and pallet, and side restraints limiting lateral movement of the container during shaking movement.
Abstract:
A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.
Abstract:
A method is provided for reformulating a chemical mechanical planarization (CMP) slurry for use in conjunction with a CMP tool having an active cycle during which the tool is being used to planarize a substrate, and a rinse cycle during which the tool is being rinsed. The method comprises (a) receiving a feed stream from the CMP tool, at least a portion of the feed stream comprising abrasive particles disposed in a liquid medium; (b) during at least a portion of the rinse cycle, sending the feedstream received from the CMP tool to a first location; and (c) during at least a portion of the active cycle, sending the feedstream received from the CMP tool to a second location where the feedstream undergoes processing to reformulate the slurry.
