Авторское резюмеВ статье на основе неопубликованных и опубликованных источников и материалов периодической печати реконструирована деятельность одного из крупных научно-образовательных центров СССР -г. Томска -в годы Великой Отечественной войны 1941-1945 гг. Рассмотрена динамика численности студентов и научнопедагогических кадров томских вузов и научно-исследовательских учреждений на протяжении войны, организации учебного процесса и научно-исследовательской работы. Особое внимание уделяется вкладу исследований томских ученых в дело победы над врагом, помощи промышленности, здравоохранению, сельскому хозяйству, транспорту, изучению месторождений полезных ископаемых. Статья предназначена для всех интересующихся историей Великой Отечественной войны, историей высшей школы и науки, а также советским периодом отечественной истории. AbstractThere was reconstructed the activity of one of the largest scientific and educational centers of the Soviet Union the city of Tomsk in the Great Patriotic War of 1941-1945 on the basis of unpublished and published sources, periodical materials. The problems of the dynamics of the number of students and of the teaching staff of Tomsk universities and research institutions throughout the war, the organization of educational process and scientific research were regarded. Particular attention was paid to the contribution of Tomsk scientists to the victory over the enemy, aid to industry, health, agriculture, transport, study of mineral deposits. This article is intended for those interested in the history of the Great Patriotic War, the history of higher education and science, as well as the Soviet period of Russian history.

Авторское резюме Великая Отечественная война 1941-1945 гг., семидесятилетие Победы в которой Россия отмечает в 2015 г., в полной мере отразилась и на жизни Томского государственного университета. Среди преподавателей и сотрудников, студентов, рабочих и служащих университета наблюдались большой патриотический подъем и горячее стремление своим личным участием дать отпор фашистам. Приказами ректора от 23 июня 1941 г. в связи с призывом в РККА были отчислены 90 преподавателей и студентов. В числе тех, кто в первые дни войны отправился на фронт, были доценты С.

The rich tradition of Siberian science and higher education is little known outside Russian academic circles. Using institutional history, this article focuses on the founding and pre-war period of the Siberian Physical Technical Institute, the establishment of its research focus and its first difficult steps to become a leading centre of R & D in Siberia. Based on archival materials, the article describes how local and national physicists justified the institute's creation by demonstrating ties with industry and building on the presence of a cohort of locally trained physicists, whose numbers were augmented by Leningrad specialists. The strength of local cadres enabled the institute to navigate civil war and cultural revolution successfully. Physicists were able to take advantage of ongoing industrialization campaigns to gain support to create the institute, although local disputes and economic problems slowed its further development. The article describes the circulation of scientific, political and philosophical knowledge between Moscow, Leningrad and the provinces, and the impact of Bolshevik rule and Stalinism on the Siberian physics enterprise.

power tools that are used in various industries have power take-off drives for aggregating various machines and mechanisms. In the agro-industrial complex, one of the most common power tools are tractors manufactured by the Minsk Tractor Plant. The drive of power take-off in these tractors is carried out at the expense of the planetary mechanism. The wheel and the solar gear of the planetary mechanism are connected to the drums, alternately stopping the drums is carried out on and off the drive. The brake tape of the firing drum connected to the sun gear is most susceptible to wear, as the drum is loaded with a torque of at least one third of the torque to the drive of the aggregated machine.Due to the design features of the existing control mechanism, the turn–on time is 1.5-2 times less than recommended for devices of this kind. As a result, there is an intense wear of the friction lining of the inclusion drum tape.Regulation of the control mechanism of adjusting screws is carried out untimely, as a result, the durability of the tapes is very low.To improve the durability and efficiency of the power take-off drive, a drive-on design is proposed by electromagnets.Applying force to the tape by electromagnets at four points, instead of one in the previous design, will improve the braking efficiency of the inclusion drum.It is possible to include electromagnets not at the same time, but with some time offset, with a gradual pressing of the tape, starting with the portion of the tape closest to the axis of its suspension. This improves the fit of the tape to the drum inclusion.In the transition from a mechanical drive to an electrical device, the control operation is eliminated, which reduces maintenance time, significantly increases the life of the brake belt and increases the efficiency of the power take-off drive.
