Abstract: A themed water amusement ride that raises guests in rafts on a lift platform to a dome. The lift platform has bays containing the rafts. The bays have tilting floors. The lift platform rotates, selectively aligning the bays with elevated slide entrances. The floors of the bays tilt the rafts into the slides, where the raft moves down the slide to a pool of water. The platform, dome, slides, lift structure, and pond are further provided with lights, sound production equipment, mechanical figures, water hoses, water outlets, and animation media to produce a show in accordance with the theme.

Abstract: Treatment of molten steel in a ladle, which comprises blowing inert gas into the ladle from its bottom, partially immersing a receptacle which covers the portion of the molten steel where the inert gas bubbles out and maintain non-oxidizing atmospheres within the receptacle with the gas so as to prevent oxidation of the molten steel by the slag.
