Abstract
Abstract The device for ultrasonic machining of articles in a liquid medium comprises two groups (2, 3) of acoustical-electrical transducers (4) arranged on an elastic element (7), filled with a liquid medium (8), in staggered order at a predetermined distance from articles being machined. The acoustical-electrical transducers (4) of the group (2) are connected to the output of an ultrasonic generator (1). The acoustical-electrical transducers (4) of the group (3) are connected to the output of the ultrasonic generator (1) through a phase-pulse modulator (5) connected to a saw-tooth voltage generator (6).

Claim 1
Independent Claim
123 words
A device for ultrasonic machining of articles in a liquid medium, comprising an ultrasonic generator and two groups of acoustical-electrical transducers, one of said groups being directly connected to an output of the ultrasonic generator, while the other group is electrically coupled to said output, both groups being arranged on an elastic element, filled with a liquid medium at a predetermined distance from articles machined in the liquid medium so that acoustical-electrical transducers of one group are disposed between acoustical-electrical transducers of the other group, characterized in that it includes such series-connected components as a sawtooth voltage generator and a phase-pulse modulator, electrical connection of one of the groups of the acoustical-electrical transducers with the ultrasonic generator being accomplished through the phase-pulse modulator.
