Abstract
1,214,560. Dosing Ca(OH) 2 . S. A. J. LILJENDAHL. 23 Dec., 1968 [29 Dec., 1967], No. 60969/68. Headings B1C, B1F and B1X. A method of dosing an aqueous Ca(OH) 2 paste 17 from a vessel 1 comprises filling the space in the vessel above the paste with water and supplying a volume of water corresponding to the desired dosing volume to the vessel so as to displace a corresponding volume of paste through outlet valve 9, the supply of water to the vessel being controlled by an automatic timing device whereby waiter is supplied for a predetermined period of time. A vibrator 12 may be mounted on the vessel to assist the settling of the paste. The automatic timing device may control a magnetically operable valve 10.
