Title: Buoyant tank carbonator pump control for post-mix beverage apparatus
Inventor: ZIESEL LAWRENCE B
IPC: B01F15/04
Filed: 1990-03-26
Abstract: A carbonator unit for a post-mix beverage dispenser having a carbonator tank (10) immersed in a liquid flotation tank (14). The carbonator tank floats up and down with changes in the amount of water and head space in the carbonator tank to actuate a switch device (34) mounted externally of the carbonator tank.

Abstract: SYSTEM FOR ELECTROLYTICALLY GENERATING  STRONG SOLUTIONS OF HALOGEN OXYACIDS                          Abstract The present invention resides in a process and apparatus for the electrolytic production of strong solutions of halogen oxyacids, more specifically for the production of such acids having a normality of about 0.1 to about 3.6 from the corresponding alkali metal salts of such acids.  The present invention comprises establishing a solution of the corresponding alkali metal salt having a molar concentration less than that at which precipitation of said salt occurs.  An electrolytic cell is provided comprising an anode compartment containing an anode, a cathode compartment containing a cathode, and a middle feed compartment intermediate the anode compartment and cathode compartment.  The feed compartment is separated from the anode compartment by a diaphragm or an anion-selective membrane, and from the cathode compartment by a cation-selective membrane.  Means are provided for introducing said alkali metal Walt solution into said middle feed compartment and for applying a voltage between the anode and cathode.  Under the influence of the applied voltage, the alkali metal ions migrate through the cation-selective membrane to the cathode, reacting with hydroxyl ions to form alkali metal hydroxide, and the oxyhalogen ions migrate through the diaphragm or anion-selective membrane to the anode reacting with protons to form halogen oxyacid.  Means are provided for maintaining the cell at a temperature in the range of about 10°C to about 40°C.
