Abstract: A theatrical device for optically exciting and delivering objects coated with luminescent material has an enclosure with an inner reflective surface with a hollow transparent excitation passageway extending therethrough. A light source illuminates the objects in the passageway for exciting the luminescent material so that the objects glow brightly. A blower moves the objects through the passageway to an outlet where the glowing objects are projected into an audience for dramatic effect.

Abstract: Self-contained closed-loop cooling systems and related methods for rapidly cooling individual beverage containers of different sizes to a suitable target temperature, in the range of 35° F. to 50° F. Each system includes a chiller, a coolant circuit with a hyper-chilled supply reservoir, a refrigerant circuit for cooling the reservoir, and an electronic controller to operate the system upon operator command. The chiller is preferably formed like a barrel, with a cylindrical array of hollow chill elements arranged about a cylindrical area into which a beverage container, such as beverage bottle or can is placed. Then, very cold coolant from the coolant supply is pumped through the array of chill elements to rapidly cool the beverage container, which makes physical contact with the hyper-chilled elements, which are thus excellent heat absorbers. The chill elements are preferably separated from one another by keystone spacers, and are flexibly held in place with a plurality of coil springs.

Abstract: A method of preparing a desired photoluminescent color pigment having a predictable color and spectral response under ambient illuminating radiation and in the dark, comprising the steps of: choosing at least one target color having a dominant wavelength and selected spectral response in the presence of ambient illuminating radiation and in the dark; and mixing by weight about 87-97.8% phosphorescent pigments, about 2-10% fluorescent pigments and about 0.2-3% common pigments, each having a dominant wavelength and spectral response near said target color, to produce said spectral response.
