Abstract: A binder system component metering apparatus for use in core sand mixing equipment comprising an elongate hollow vessel of substantially greater length than width and having upper and lower end portions, valves located in a lower end portion of the elongate vessel for introducing via hydrostatic pressure, liquid binder system components into the vessel so that as the vessel is filled the liquid presents an upper surface that rises vertically, and sensor located in the upper end portion of the elongate vessel to continuously sense the position of the liquid surface at infinite locations along the length of elongate vessel whereby the upper surface rises with minimum turbulence.
Abstract: Foundry sand testing apparatus, method and system are provided for testing foundry sand. A computer foundry sand testing system includes at least one sensor for sensing predetermined characteristics of the foundry sand and for generating a signal. A processor coupled to the sensor processes the generated signal. A display is operatively controlled by the processor for displaying predetermined test information responsive to the generated signal. Predefined displays for receiving user selections and for displaying of test information are automatically generated. The generated displays of test information include real-time stress-strain curves and multiple calculated values utilizing the stress-strain curves.
