Abstract: A housing defines a volume to retain a fluid. The housing defines an opening along a top of the housing to receive fluid. The housing also defines a separated fluid outlet. A lid is arranged to cover the opening. In some embodiments, the lid defines a hole therethrough. Within the reservoir is a plunger with a paddle. The paddle is arranged and configured to move and retain cold materials within the reservoir, such as ice, towards the outlet. The plunger can include a shaft extending through the hole. The shaft can be attached to a handle at a first end of the shaft. In some embodiments, the paddle can be coupled to a second end of the shaft positioned within the volume of the housing. The plunger can be vertically slidably movable through the hole to vertically move the paddle within the volume.

Abstract: Various systems, devices, and methods of determining an amount of carbon dioxide in a gas source in a carbonation system are provided. A carbonation system is one example of a treatment system to which the systems, devices, and methods described herein apply. In general, a carbonation system can be configured to determine an amount of CO2 in a gas source, such as a CO2 canister, removably coupled to the carbonation system. The carbonation system can also be configured to provide a notification (e.g., audible alert and/or visual alert) to a user of the carbonation system indicative of the determined CO2 amount.

Abstract: A rotisserie system includes a cooking oven enclosure including a driven gear at one inner wall thereof. A spit assembly support framework has a drip pan and first and second side racks upstanding from the drip pan each including a spit assembly support. A spit assembly comprises a driven wheel including gear teeth driven by the driven gear, an inward bushing supported by the spit assembly support, and a socket for a spit rod. The spit assembly also includes a handle assembly with an inward bushing supported by a the spit assembly support, a yoke assembly including a center spit rod extending into the driven wheel socket, and one or more additional spit rods extending at least partially along the length of the center spit rod.
