Abstract
434,999. Solidifying carbon dioxide. MASCHINENFABRIK SURTH ZWEIGNIEDERLASSUNG DER GES. FUR LINDE'S EISMASCHINEN AKT.-GES., Surth, near Cologne, Germany. Sept. 20, 1934, No. 27094. Convention date, Oct. 14, 1933. Addition to 404,833. (Class 8 (ii)] Liquid carbon dioxide under pressure higher than triple point pressure is cooled further, in absence of its vapour, in a vessel m by the expanded gas before passing to the icemaking vessel b, the pressure in the vessel b being maintained in equilibrium with that in the supply vessel a through a valve e. Vapour is drawn off from the ice - making box through the diaphragms c controlled by valves d.
