Acoustic Gas-Jet Generators of the Hartmann Type,lerated by means of high-intensity elastic vibrations. Among these processes are some that take place in a gas medium. Thus, by using sound vibrations at intensities in excess of 0.01 W/cm., it is possible to realize the ultrapurification of dust-ridden gases , to accelerate considerably the br

Ferrite Magnetostrictive Radiators, equipment for the active technological application of ultrasound in the frequency range from 15 to 60 kc. The materials used for these transducers are usually metals and alloys having magnetostrictive properties: nickel, iron—cobalt alloys (of which Permendur is the best-known representative), iron

Ultrasonic Focusing Radiators,radiator material and heating due to electrical and mechanical losses; besides lowering the durability, heating can reduce the electromechanical coupling coefficient of the transducer material. Artificial cooling greatly complicates the device itself and the way in which it is used, and its very pur
