An ultrasound reactor having a reactor body, a reactor tube disposed within the reactor body and a magnetostrictor transducer comprising at least one annular element concentric with, and mounted to an external wall of said tube and a process for ultrasonic treatment of a reaction material are disclosed. An optional accessory switch may be included to provide the ability to prevent the accessory from turning on regardless of engine speed. At the field cabinet, DSLADSL signals are removed from the metallic telephone line and are then communicated between the field cabinet and the central office using fiber optic broadband transmission. A register file 20 has a set of registers, for storing values produced by the executed instructions. In addition, the algorithm makes adjustments to the zone boundaries based upon a misalignment between the centers of the lens being used and the APS array. A high degree of operational security and redundancy may be provided, whereby the coolant in the first cooling circuit and the second cooling circuit flow counter-currently through a stator cooling circuit in the region of the electrical submarine drive motor.
