Abstract: Beverage carbonation devices employing carbon dioxide-containing molecular sieves. Upon contact with aqueous solutions carbon dioxide is released from such molecular sieves and thereupon dissolves in the liquid to provide a carbonated beverage.

Abstract: A rigid composite body containing crystalline molecular sieves and having liquid-permeable channels extending in a substantially vertical direction from one surface of said body to the interior thereof, preferably to an opposite surface, is charged with carbon dioxide so that when brought in contact with water or an aqueous beverage, the carbon dioxide will be released from the molecular sieve composite body to carbonate the solution. Such rigid, composite bodies are secured in a sealable, nestable, stackable container which provides a convenient and efficient means for dispensing such composite bodies in combination with a dry instant beverage mix for the preparation of carbonated beverages upon the addition of water.

Abstract: A process for producing uniformly shaped chip-type products having a surface design thereon. The process provides chip-type products having a series of substantially parallel alternate arcuate ridges and grooves extending across both surfaces which effect a rippled appearance to the products wherein the rippled configuration is impressed only on one surface of the dough by a mill roll having an annularly grooved surface.
