A mill for pulverizing rock and other material. The mill includes a series of rings each having nine flat faces extending around the interior surface of the ring. The rings are arranged in a vertical column. A baffle plate possessing a central aperture is disposed between each pair of adjacent rings. A vertically extending axle extends through each of the central apertures of the baffles. A rotor is disposed between each pair of adjacent baffles and is mounted on the axle for concurrent rotation therewith. The periphery of each rotor possesses a plurality of curved blades so that when the axle is rotated, the rotor creates a suction force, which hurls the rocks forcibly toward the flat surfaces of the rings. Some of the rocks ricochet off the flat surfaces and collide into the rocks being hurled toward the flat surfaces, which collision causes the rocks to break apart. The rocks are delivered into the top of the mill, are hurled by the top-most rotor toward the faces of a ring, pass through the central aperture of the lower, adjacent baffle plate, are hurled by the next lower rotor toward the faces of the next lower ring, etc., in continuous operation until the rocks are disintegrated to the desired particle size.

This invention is directed to a method and an apparatus for carrying out that method of transferring an unsealed container of a liquid containing dissolved gas from a filling station to a sealing station where a closure is applied while avoiding foaming and frothing of liquid from the container and the attendant loss of liquid by subjecting the container and contents during such transfer to an ambient super atmospheric pressure.

A transducer assembly which generates a cone shaped radiation pattern concentric with a selected axis is formed by a piezoelectric element mounted in a cylindrical resonant cavity defined by a Helmholtz chamber. Circumferentially spaced apart and radially aligned circular apertures are formed in the chamber's cylindrical side wall and an inclined reflecting plate is spaced apart from the apertures a selected distance. The plate extends outwardly from the chamber at an angle of less than 90.degree. to the chamber axis. The cone shaped radiation pattern is produced by generating a plurality of discrete spherical radiation patterns, combining these patterns to form an annular radiation pattern and partially reflecting the annular radiation pattern from an inclined reflection plate extending at an angle to the chamber axis of less than 90.degree. to produce a cone shaped radiation pattern.
