    • A beer foaming process and apparatus in which a smooth stable foam is formed by intimately admixing a nitrogen containing gas, preferably air, by a Venturi effect in a nozzle positioned on the beer tap. The nozzle has a mixing chamber with a perforated plate at its intake end to divide the flow of beer from the keg into smaller streams of higher velocity in the mixing chamber, intake ports in the side walls of the chamber for admitting gas into the chamber, and a screen of 30 to 200 mesh at the discharge end of the nozzle to form the stable foam discharged from the chamber.
    • 一种啤酒发泡方法和装置,其中通过在位于啤酒丝锥上的喷嘴中通过文丘里效应将含氮气体,优选空气密切混合而形成平滑稳定的泡沫。 喷嘴具有在其进气端处具有多孔板的混合室,以将啤酒从小桶分流成在混合室中更高速度的较小流,用于将气体引入室中的室的侧壁中的进气口, 并且在喷嘴的排出端处具有30至200目的筛网,以形成从室排出的稳定泡沫。

    • This application discloses a composition and method for gelling volatile liquids and the gelled volatile liquid. The composition comprises a cellulose ester coated with up to about 50% paraffin. When the paraffin coated particles of the cellulose ester are used to gel a volatile liquid, the gelled structure has a slower evaporation rate than the volatile liquid alone. The process of this invention includes the steps of adding melted paraffin to a cellulose ester, cooling, and stirring until free flowing granules are formed. When the granules are added to an organic solvent, the solvent gels and has a very slow rate of evaporation.
    • 本申请公开了一种用于凝胶化挥发性液体和凝胶状挥发性液体的组合物和方法。 该组合物包含用高达约50%的石蜡包被的纤维素酯。 当纤维素酯的石蜡包覆的颗粒用于凝胶化挥发性液体时,胶凝结构的蒸发速率比单独的挥发性液体慢。 本发明的方法包括将熔融石蜡加入到纤维素酯中,冷却和搅拌直到形成自由流动的颗粒的步骤。 当将颗粒加入到有机溶剂中时,溶剂凝胶并且蒸发速度非常慢。
