Abstract: A carbonated beverage maker includes a water reservoir, a carbon dioxide creation chamber, and a carbonation chamber. The water reservoir holds ice water and has a first impeller and a shroud surrounding the first impeller. The carbon dioxide creation chamber contains chemical elements and receives warm water. The chemical elements react with each other to create carbon dioxide when the warm water is introduced to the carbon dioxide creation chamber. The carbonation chamber is connected to the water reservoir and the carbon dioxide creation chamber. The carbonation chamber has a second impeller that includes a stem portion and blades. The stem portion and the blades define conduits therein. The blades create a low pressure region in a lower portion of the carbonation chamber such that carbon dioxide from the carbon dioxide creation chamber flows through the conduits to the low pressure region.

Abstract: A peristaltic pump includes a rotor and first and second rollers mounted on the rotor. The first and second rollers rotate between a disengaged, initially engaged and a fully engaged position with respect to a section of tubing. The rollers begin to occlude the tubing when in the initially engaged positon and fully occlude the tubing when in the fully engaged position. The pump also includes an encoder and a rotor controller. The encoder monitors the position of the first and second rollers as the rotor rotates. The rotor controller is in electrical communication with the encoder and controls the operation of the pump and rotor. The controller stops the rotation of the rotor in response to a stop command and based upon the monitored position of the first and second rollers such that either the first or second roller remains in the fully engaged positon.
