138	Method for regenerating the sand of sand molds and sand cores	US14188377	2014-02-24	US08985184B2	2015-03-24	Harald Schwickal; Matthias Huebner
For regenerating the sand, which is obtained from sand molds and/or sand cores, which are produced from the sand and soluble glass as a binder and are used in metal casting, the sand obtained from the sand molds and/or sand cores is subjected to a mechanical regeneration stage and a thermal regeneration stage. During or after the mechanical regeneration stage, the obtained sand is mixed with a hardener for soluble glass.

140	Method for controlling an expandable mixture	US11921956	2006-06-09	US07766543B2	2010-08-03	Yusuke Kato; Toshihiko Zenpo; Norihiro Asano; Kazuyuki Nishikawa
A method is disclosed that monitors and controls the condition of an expandable mixture before injecting it in a mold and that maintains the conditions for filling so as to make a casting mold having a uniform strength.The method comprises (a) a step of measuring the temperature of the expandable mixture, (b) a step of determining each reference value of the one or more characteristic parameters that show a characteristic property of the expandable mixture based on the measured temperature and the predetermined relationship between a characteristic property of an expandable mixture and its temperature, (c) a step of measuring the one or more characteristic parameters that show the condition of the mixing of the expandable mixture, (d) a step of determining whether each characteristic parameter is within the corresponding reference value, and (e) a step of determining whether the expandable mixture has been made under the normal condition or if it needs to be adjusted.
