Abstract: Abstract of the Disclosure Chemically treated glass fiber strands can have a reduced tendency for fiber breakage and fuzz ball production through the present invention.  The present invention constitutes glass fiber strands where the glass fibers have a moisture-reduced, non-homogeneous residue having a lubricious phase, where the residue results from an aqueous chemical treating composition having:  a lubricating system; an aqueous soluble, dispersible or emulsifiable film forming polymer that produces a non-rigid film; and water.  The lubricating system has one or more polyoxyalkylene polyols and/or polyalkylene polyols with an effective high molecular weight in an effective amount of the solids of the aqueous chemical treating composition to form a lubricious phase and a cationic lubricant.  The lubricating system can also have polyethylene glycol, wax, internally lubricated organo silane esters and mixtures thereof.          The film forming polymer can be a polymer that results in a film less rigid than unplasticized polyvinyl acetate such as polyvinyl pyrrolidone, carboxylated styrene butadiene copolymer, starch, elastomeric polyurethanes and mixtures thereof.  The aqueous chemical treating composition can also have one or more organo silane coupling agents in an effective coupling amount.

Abstract: APPARATUS AND METHOD FOR CONTROLLING SAND MOISTURE             Abstract of the Disclosure An apparatus for controlling the moisture content of sand as it is transported from storage to a mold making apparatus.  A conveyor is used to transport a substantially uniform layer  of sand at a known rate.  The electrical resistance across the sand layer is measured using a series of electrically conductive members that extend into the sand.  A thermocouple or other contact device is used to obtain an average temperature of the sand layer.  The electrical resistance and average temperature measurements are used in a signal processor to calculate a starting moisture content for the sand.  The signal processing unit also calculates an amount of water that should be added to the sand to achieve a computed moisture content value.  The signal processing unit further controls the means for adding the water to the sand so that the computed moisture content value is obtained.
