INFORMATION ON THE BOOK ' RE ULATION'OF MACHINES" BY Z. SR. BLOKE
This book was based mainly on a series of special lectures organized by
the Chair of the Theory of Mechanisms and Machines, Moscow Mechanics Institute,
and intended, decor'ding tbotlie?^aut9ibr, to 6kfset,.AYie'S epBkiCj iT

The author notes that available textbooks on the theory of mechanisms and
machines almost completely ignore the important present-day aspects of regula-
tion and that machine-design engineers without this supplementary training can
hardly consider themselves qualified to solve the complex problems arising in
the design of machines with automatic controls. Furthermore, he states, engi-
neers who are presently engaged in practical work on the regulation of machines
know very little about the latest achievements in this field, particularly in
the development of methods for analyzing the stability of modern ?lectrical and
electronic systems. This deficiency in the training of engineers, the author
explains, has become even more pronounced in recent years with the advent of
automatic profiling machines, automatic-production lines and plants, jet engines,
etc.
The author acknowledges the aid of the following colleagues of the Chair of
the Theory of Mechanisms and Machines, Moscow Mechanics Institute: T. T. Beloul-
sova, Ye. R. Vanchinova, A. M. Rubinchik, and M. I. Freydlin.
