  • Ultrasonic reactor and process for ultrasonic treatment of materials
    Patent number: 7504075
    Abstract: An ultrasound reactor (30) having a reactor body (1), a reactor tube (9) disposed within the reactor body and a magnetostrictor transducer (11) comprising at least one annular element (28a-d) concentric with, and mounted to an external wall of said tube and a process for ultrasonic treatment of a reaction material are disclosed. The transducer is mounted on the reactor tube in such a way so as to transmit ultrasound radiation to the interior of the tube and to induce an upwardly flowing cavitation stream whose longitudinal axis substantially coincides with a longitudinal axis of said tube, causing physical changes to the reaction material.
    Type: Grant
    Filed: May 29, 2003
    Date of Patent: March 17, 2009
    Assignee: Nano-Size Ltd.
    Inventor: Evgeny Marhasin
  • High power ultrasonic reactor for sonochemical applications
    Patent number: 7157058
    Abstract: Ultrasound device having a reaction chamber, which includes a magnetostrictive transducer and a horn transmitting ultrasound radiation substantially uniformly throughout the reaction chamber. The horn is hollow and is constituted by a cylinder having an empty inner chamber at its core defining a resonance chamber, which may be cylindrical and may comprise a plurality of sections of cylindrical shape or a central section of larger diameter and two terminal sections of smaller diameter.
