Abstract: A machine for making ice cream or other frozen comestible from a liquid. The machine includes an outer housing in which is inserted a removable freezing chamber which can be independently frozen and replaced in the chamber. Internally of the freezing chamber is a compartment in which can be placed a rotary assembly including a plurality of radially extending blades rotatable with the compartment. The blades include slits at their outer edges defining fingers for atomizing, aerating and moving the frozen liquid through the freezing chamber to its outlet. The blades are of a hard, elastic, low friction material with the outer tips of their fingers lying on an outer diameter larger than the inner diameter of the freezing compartment. The blades are then stressed when inserted into the freezing chamber to forceably engage the inner cylindrical surface of the freezing chamber and are twisted like a helix towards the outlet of the freezing chamber.

Abstract: A grilling appliance having a lower housing section containing a lower grill plate and an upper housing section containing an upper grill plate. The upper section is movable between an open position for placing a food article to be grilled on the lower grill plate, and a closed position defining with the lower housing section a heating chamber containing the two grill plates for grilling therebetween food articles. A water container is included in one of the housing sections for receiving water to saturate the heating chamber with water vapor during the grilling of the food article.

Abstract: An ice-cream making machine, comprises a receptacle for receiving the liquid ingredients to be used for making the ice-cream, a cooling duct conveying the ingredients from the receptacle to an ice-cream outlet of the machine, an air inlet into the cooling duct, a rotor including a plurality of blades rotatably driven within the cooling duct and effective to atomize the liquid ingredients as particles mixed in air and to direct freezing, and a valve controlling the rate of flow of the air from the air inlet to the cooling duct thereby enabling the machine to vary the density of the ice-cream produced. The machine includes a further valve for controlling the rate of flow of the liquid ingredients from the receptacle to the cooling duct to selectively effect a first rate of flow for producing ice-cream, a lower rate of flow for producing ices, or a higher rate of flow for producing cooled beverages.
