Abstract: A new METHOD AND APPARATUS FOR AUTOMATICALLY PRODUCING A SMALL BLOCK OF SOLID CARBON DIOXIDE is disclosed and described. The new method and apparatus is comprised of an electrical solenoid operated liquid fill valve, a dry ice block forming chamber having porous walls and/or lining attached to or forming its walls, a hydraulic cylinder and ram, a hydraulic pump assembly, a dry ice block forming chamber door, an electronic solenoid operated pneumatic valve, a pneumatic cylinder and ram, and a digital electronic microcontroller. A pressurized cryogenic Dewar-type tank containing liquefied carbon dioxide provides the cold carbon dioxide input fluid to this invention.In operation, liquid carbon dioxide is forced out of the pressurized Dewar-type tank to form carbon dioxide snow, with said snow being deposited into a dry ice block forming chamber having porous walls and/or lining attached to or forming its walls.

Abstract: A carbonated beverage delivery system having at least two syrup storage tanks. Each storage tank is provided with a valve that allows air to vent from the tank during delivery, acts as a nozzle to deliver cleaning solution during clean-up operations and, most significantly, meters the amount of fluid delivered to the tank and prevents inadvertent overfill. The tanks are also provided with a syrup feed pipe and drain pipe for filling and discharging the tank, respectively. The drain pipe can be connected to a mixing valve that also receives carbon dioxide and water from separate sources. These components are mixed at the mixing valve to create the desired carbonated beverage which is then delivered to a beverage dispenser. The feed pipe can be connected to a delivery truck supply tank such that its supply of syrup can be replenished. The volume of syrup carried by the truck supply tank is less than the total volume of all the storage tanks to be filled from the supply tank.

Abstract: There is disclosed a syrup delivery system for carbonated beverages which provides delivery of beverage syrup from a syrup container to a beverage mixer. The syrup delivery system comprises a source of pressurized gas, conveniently the CO.sub.2 gas source which is also used to carbonate the water used to mix the carbonated beverage, and a syrup container. The syrup container comprises a rigid drum having an opening with a closure and a pressurizing fitting for connection to the source of presurized gas. A collapsible bag for holding the syrup is fitted inside of the rigid drum and is connected by means of a double ended connector through the closure to the beverage mixer. In operation, the CO.sub.2 pressurized gas is introduced into the rigid tank between the inside of the tank and the outside of the collapsible bag thereby forcing the syrup out of the bag and to the beverage mixer at a constant pressure.
