hermetically sealed, which permits use of flight altitudes at 

 10,000 meters. Through further improvement of this type of 

 aircraft, there appeared the more comfortable, multi-seat (170) 

 passenger airplane, the TU-114 (1956) with turboprop engines. 

 Continuing the work of N. E. Zhukovskii, Tupolev worked on 

 aerodynamic calculation for airplanes and on the strength of 

 material. Besides the designing of airplanes, Tupolev con- 

 structed various types of naval torpedo boats. 



In March 1962, Tupolev was re-elected Deputy from 

 R.S.F.S.R. to the Supreme Soviet. He has attended Pugwash 

 Conferences.

USHAKOV, SERGEI NIKOLAEVICH (Organic Chemist) 



S. N. Ushakov was born September 16, 1893. In 1921 he 

 graduated from the Petrograd Polytechnic Institute. He was 

 made professor at the Leningrad Technological Institute in 

 1930; at the same time, 1931-41, he worked at the Scientific 

 Research Institute of Plastics of which he was Director in 1931- 

 38. In 1945-49, he was Director of the Scientific Research 

 Institute of Polymerized Plastics. He was also the Director, 

 in 1948-53, of the Institute of High Molecular Compounds of the 

 U.S.S.R. Academy of Sciences. Ushakov has been a member of 

 the Communist Party of the Soviet Union since 1943. He was 

 elected, in 1943, a Corresponding Member of the U.S.S.R. 

 Academy of Sciences. In 1942 and 1950 he received Stalin 

 Prizes, and in 1943 was an Honored Scientist of the R.S.F.S.R. 



The investigations of Ushakov are concerned with phenol 

 aldehyde condensation, the synthesis of vinyl polymers, cellu- 

 lose esters, the polymerization and copolymerization of unsatu- 

 rated compounds, the preparation of polyvinyl alcohol and its 

 acetals, and the reactions of high molecular compounds. He 

 developed the technology of producing synthetic camphor, ethyl 

 cellulose, benzyl cellulose, poison of phenolic resins, polyvinyl 

 acetate, and polyvinyl alcohol.
