Pages of the life of M.V. Timofeev-Ressovsky in the material historical sources

Aim. To investigate and to enter into scientific circulation material historical sources related to the biography of M.V. Timofeev-ResSovsky. Methods. The paper used both general scientific (historical, logical) and special (subject-chronological, retrospective) methods. Results and discussion. The role of Kyiv in shaping the future scientific vocation of M.V. Timofeev-Ressovsky, the work of a scientist in Germany and the reasons why he did not return to the USSR in the late 1930s, outlines the facts of Timofeev-Ressovsky life after the Second World War. The scientific activity of scientist has been briefly analyzed. Conclusions. The analysis of material historical sources made it possible to investigate and bring into scientific circulation the objects of phaleristics, numismatics (medallic art), philately and a rather rare object of collecting – telephone cards of the Russian Empire, the USSR, Russia, the former GDR and Germany, to tell about some pages of the biography of M.V. Timofeev-Ressovsky. Keywords: M.V. Timofeev-Ressovsky, history of biology, phaleristics, numismatics, philately, telephone card.

Study on the Sheet Escape and Feeding Mechanism Using Ultrasonic Vibration (1st Report) - Design Concept and Its Experimental Investigation -

This paper describes sheet feeding method and its design concept using the ultrasonic vibration actuator. The ultrasonic vibration is generated by two sets of piezoelectric actuators. It is an elliptic vibration mode, which rotates two vibration modes in the <I>Y-Z</I> and <I>X-Y</I> planes. This paper also presents a direct drive method using vibratory rotor and an indirect drive method using the idling rotor about sheet feeding mechanism, and it verifies theoretical relations between amplitude UZ1 and sheet feeding speed <I>VH</I> ,<I>VH</I>* and feeding force <I>FH</I> ,<I>FH</I>*. As a result of fundamental experiments, it was proved that a sheet, such as paper and telephone card, could be easily fed using either of their methods and a the highly reliable and compact sheet feeding mechanism could be obtained.
