Abstract: A method and apparatus for producing liquified Alternative Supplemental Cementitious Material (ASCM) from an uncured concrete slurry. Uncured concrete slurry is received into a receiving hopper, diluted with water, and pumped upward through a slurry discharge conduit to an aggregate separator that screens the gravel and sand for separate discharge. The remaining ASCM entrained water flows into a holding tank. The ASCM settles to the lower portion of the holding tank. The holding tank stores the remaining water for re-use diluting uncured concrete slurry. The ASCM is liquified and moved towards the ASCM discharge port by an agitator system located in the bottom of the holding tank. From the discharge, a pump delivers the liquified ASCM through a conduit for discharge. The discharged ASCM can be used as a partial replacement for Ordinary Portland Cement and as an ingredient in flowable fills.

Abstract: A diverter valve housing has two outlets and one inlet for receiving a flow of air conveying a continuous strip of material, and a diverter duct or tube is pivotally supported within the housing on a pivot axis adjacent the inlet. The diverter tube has an outlet end portion supporting a pair of inclined cutting blades which cooperate with a cutting blade supported by the housing between the outlets for alternately and quickly chopping or cutting the strip of material when the outlet end portion of the diverter tube pivots between the two outlets of the housing. Sealing members connect the diverter tube to the housing and form stops for the diverter tube. A fluid cylinder is pivotally connected to the housing and has a piston rod pivotally connected to the diverter tube for rapidly pivoting the diverter tube between the two outlets.

Abstract: A continuous supply of scrap material from a papermaking or converting process is transferred by a venturi inducer system including a housing surrounding a tubular intake duct which defines with the housing an annular air chamber connected to receive pressurized air from a motor driven blower. The housing has a tapered or frusto-conical portion connected to a tapered material outlet duct and which cooperates with the inner end of the intake duct to define an annular nozzle opening. Long adjustable bolts connect the intake duct to the housing outboard of the housing and provide for externally adjusting the intake duct axially for precisely selecting the area of the nozzle opening to optimize the air flow through the nozzle opening for pulling and transferring the material while minimizing the electrical power required to operate the blower motor.

Abstract: An apparatus and method for reclaiming uncured concrete are disclosed. The apparatus includes a hopper with water inlet for introducing water to the hopper. The outlet of the hopper is connected to a separator that is suitably connected to the hopper to receive material therefrom. A screen is positioned in the separator to separate material flowing therethrough. The separator has two outlets for removing material from the separator.
