This citation summarizes a one-page announcement of technology available for utilization. A proposed single-axis acoustic resonance system incorporates concave drivers and reflectors to increase the levitation force up to a factor of 6 as compared to conventional flat-shaped elements. A ring element inserted between the concave surfaces controls the standing-wave pressure pattern, particularly critical in levitating liquids. In the new arrangement a cylindrical aluminum reflecctor and a driver have spherically-machined concave surfaces facing each other and separated by a distance equal to the smaller raduis of curvature of one of the elements. ...FOR ADDITIONAL INFORMATION: Contact: The Patnet Counsel, Marshall Space Flight Center, Alabama.
