Assignee:

Liquid Carbonic Industries Corporation - Chicago IL

International Classification:

B01F 304

US Classification:

210743

Abstract:

A method and apparatus for carbonating a liquid by creating a pressurized atmosphere of carbon dioxide in a container, spraying a liquid, including a caustic containing liquid, into the atmosphere to cause an interaction between the liquid and the carbon dioxide, collecting a pool of liquid in the bottom of the container, and sparging carbon dioxide under pressure through the pool, and an apparatus for same.

Abstract:

A cryogenic fuel powered vehicle is disclosed. A cryogenic fuel, such as liquid nitrogen or other liquified gases, is stored in a container at a selected pressure. The apparatus includes a suitable container, a heat exchanger for adding heat to the cryogenic liquid to cause it to expand and convert to gas, a valving apparatus which controls the rate of flow of the expanded gas, and a power plant formed of at least one cylinder having a double acting piston. The double acting piston has inlet and exhaust valves connected to it. The relative timing of the opening of the intake valve is related to the movement of the piston by a cam and cam follower to reduce the gas pressure in the piston at the end of each stroke practically to zero to eliminate waste of the cryogenic fuel. The valve system is adjustable to accommodate depletion of the cryogenic storage container.
