An analysis of the process of filling cavities in articles with a control gas in leakage testing is presented. Based on the results of the analysis an algorithm that describes the process of filling cavities with a gas that produces a reduction in filling time is proposed. The proposed algorithm provides a foundation for automation of leakage testi...

Design flaws of known rotary pulsation apparatuses are analyzed. A new rotary pulsation apparatus design is proposed. The essential technical feature of this design lies in imparting an irregular shape to the flow channels, which ensures increased agitation of the emulsion flow and formation of a more uniform of emulsion structure.
