Abstract: Vacuum insulating and construction materials are provided by producing bubble containing, solid materials such as individual bubbles, multiple bubbles, foamed material, and the like in an environment of less than atmospheric pressure and enclosing the bubbles produced in an air-tight encapsulating material while still in the environment of less than atmospheric pressure or encapsulating natural material containing chambers having gas-porous enclosing walls. On being moved into an environment of atmospheric pressure the bubbles retain their vacuum quality.

Abstract: The invention is directed to a carbonated beverage dispenser and to a method of dispensing carbonated beverage. The dispenser comprises a canister having a side wall, a bottom wall and an open end with a removable lid for closing the open end during operation. A dispensing tube having a puncturing end is provided in the bottom of the canister for puncturing a beverage container loaded into the canister. The dispensing tube is connected to a flow control valve for controlling dispensing of beverage from the container. Low pressure beverage containers such as plastic or glass bottles and aluminum cans can be used in the dispenser by shaking the canister and container of beverage therein to agitate the carbonated beverage and release dissolved carbon dioxide gas prior to dispensing a serving in order to eventually dispense the entire contents of the beverage container.
