ABSTRACT: Class 21c, 62 Nr 120244 (597507/24 of 17 April
1958). 1) A 91@vosystem as in title, containing
an amplifier to the input of which is su-pplied. the
mismatching signal, and motor connected to its out-
put and driving the control element. To increase
the accuracy of the speed synchronization by ob-
taining the mismatching sign 1 in the form of three
alternating voltages with 120 phase shift, and
with frequencies, depending upon the speed-mismatch-
ing value, two three-phase tachometer generators
are applied as the mismatch pickups. The windings
of these generators, A,, B11 Cl, and A2. B;)J C21

TITLE: Soviet Scientists on the Exposition (Sovetskiye uchenyye
o vystavke)
PERIODICALt Vestnik Akademii nauk SSSR, 1958, Nr 11, pp 112-113 (USSR)
ABSTRACTt The authors were mainly interested in exhibits from the field
of automation. In their opinion the Belgian pavilions
presented the greatest number of interesting exhibits. They
mention the exhibits of some large Belgian firms as well as
of Belgian branches of American firms (digital comp-aters which
can not only be used for office and banking operations, but
also for the automation of production processes; a -ontact-
less automatic te3qphone exchange for 36 parties, ani other
features). In the field of metalworking machinery with automatic
controls the pavilions of the USSR,Czechoslovakia, Great
Britain and Belgium are mentioned as worthwhile seeing, whereas
the corresponding exhibits in the US pavilion are called
somewhat less interesting. The Soviet pavilion contained

IM -8 and other exhibits which could be operated by the
visitors in contrast to other pavilions. Finally the author
states that some of the exhibits :in the Soviet pavi'ion
were less effectively arranged than those in the Cze@ch
pavilion. Furthermore, he expresses his astonishment at the
fact that the USSR exhibited several obsolete recording
instruments. There is 1 figure.
