Abstract: A gas-fired atmospheric pressure steam humidifier having high efficiency and ultra-low NOx(3) emissions is disclosed. In some examples, the gas-fired humidifier can have an efficiency of greater than 90 percent and a NOx(3) output of less than 20 parts per million (ppm). In one aspect, the humidifier includes a secondary heat exchanger having a first heat exchange section for pre-heating combustion air and a separate second heat exchange section for pre-heating make-up water, wherein the first and second heat exchange sections are in heat transfer communication with exhaust gases generated by the gas-fired burner and combustion blower assembly. In some examples, the first heat exchange section includes orifices for enabling flue gas recirculation.

Abstract: A system and method for reducing the amount of caffeine in an existing volume of brewed coffee. The brewed coffee contains a predetermined level of caffeine. To reduce the caffeine, a caffeine filter is provided. Furthermore, a coffee receptacle is provided to hold the decaffeinated coffee. A filter chamber is positioned over the coffee receptacle. The caffeine filter is placed in the filter chamber. Brewed coffee is dripped, poured, or otherwise advanced into the filter chamber. At least some of the brewed coffee flows through the caffeine filter and into the coffee receptacle. This reduces the level of caffeine of the filtered coffee entering the coffee receptacle. The system also enables a single source of brewed coffee to produce cups of both regular coffee and decaffeinated coffee, using only one type of regular ground coffee.

Abstract: The present invention is a device and method for selectively dispensing at least one target compound into a selected environment. A target compound is dissolved within an elastomer compound in a concentration that supersaturates the elastomer compound. The elastomer compound is then shaped into a selected form that is conducive to placement within the selected environment. The target compound within the elastomer compound begins to bloom to the surface of the elastomer compound where it is exposed to the surrounding environment. The bloom of the target compound into the surrounding environment continues until the concentration of the target compound within the elastomer compound reaches its saturation point. As such, the duration of the bloom of the target compound from the elastomer compound can be regulated by the concentration of the target compound within the elastomer compound, the volume of the elastomer compound and the surface area of the elastomer compound.
