From the output of the synchronizer 4, enter ka 0dl of industrial water at a frequency of 2 kHz

FIG. 2e, w, h. The Ga-6p blocks are formed by so-called detachable converters, and the control pulses (f (P. 2i, k, p) of the transducers are excited so that the corresponding areas of the antinodes of the air) corresponding to them (using switches 7a-7n). Do not need an impulse, but also a turn-off impulse. Currents at the outputs of the 7a-7p converters

Claims (1)

shown in FIG. 2 m, n, o, p and p are the time-30 inventive formula of acoustic pressure, Device (device, intensity is ultrasonic) The device for excitation of ultrasonic vibrations due to switching of oscillations, containing ultrasonic direct current of the oscillator and nesin-generator connected to it through variable-phase excitations of control switches, variable AC current converters and Za-Zp converters (with an emitter synchronizer, the input connected to the generative generator simultaneously serves a current by a magnetometer, characterized by the fact that the current does not change and the excitation current), in order to increase the intensity alternately one after the other. In order to create ultrasonic vibrations, an ultrasonic field was inserted into it, 9f (}) an acting distributor of control pulses and a large volume of fluid with pain-controlled switches of constant current values of the average total bias magnitude, with the input the field, several converters include a control pulse divider connected to a series, in a mode that does not coincide with the synchronizer output, and the outputs of the sub-phase of short-term inclusions are transferred to the switch control units E insufficient time to form a time-variable current outputs are poEYuoedivitoy cavitation zone, and a length-Nena to respective inputs of switching off cycles, the time sufficient teley AC and switches for returning cavitation polosteyposto direct current podmagnnchivani, CONNECTION zarodyschey initial state. With these converters, the total turn-on time of the converters is adjusted to the total system operation time. Sources of information received in BHBS In order to form a large amount of information during the examination: pulsing patterns need a certain time. Therefore, by establishing Gershgal D, A ,, Fridman V, M, Ul1 UG the short periods of inclusions can be finished-developed, technological equipment, from the fact that the number of pulsating by-M., Energie, 1976, p. 100-108 .. bones formed during the time of inclusion 2, Author svIpyayutvo USSR the floor was small.
