ABffMCT: The radiation widths of a number of neutron resonances of zinc, mo1ybdenM,._.,
niobium, and rubidiun isotopes were investigated with the OlYaI (Joint Institute of
Nuclear Research) pulsed m-actor by tranwission, rvdiative neutrcn capture, and self-
indicat-ich-Itechniques. The use of different measuring techniques is claimed to result
in grvatiii~'accuracy and in a larger number of radiation widths, compared with the
usually employed measurement of transmission only. Several previously unknown re--
scnances were detected for, zinc, at 288 ev (Zn64) and 328 ev (Zn66), and more accurate
values of the spin and radiation widths were obtained for other resonances. A maximm.
was observed in the dependence of the radiation widths an the neutron number N at
N -_ 43 - 44, and a minimm at N = 38 -- 40, It is also concluded that the appreciable
variation in the radiation widths from nucleus to nucleus are associated with the
neutron number. "We thank L,-M. rrank and F.,L Shapiro for their interest in the

ABSTRACT: The authors studied the regions of vitrification and sequence and
character of crystallization in samples of the spinel-silica system and several
samples, the composition of which were located in the ternary field of primary
crystallization of the magnesia-alumina spinel. Particular attention was given
to the identification of metastable phases formed first which are chiefly
responsible for the structure and properties of glass-crystalline products.
X-ray diffraction and optical analysis were used to identify the crystallization
products, and the change in the microstructure of these crystalline phases as
a function of temperature and composition was studied. In samples containing

ABSTRACT: To synthesize cordierite, the authors used agalmatolite from the Aktau.
,deposit (Uzbek SSR) to find whether it would be possible to use the kaolinite-
,;-diaspore-pyrophyllite rocks of this deposit in the industry of the Central Asia
;Economic Region. Magnesium oxide was added to the agalmatolite.in the amount of
i13.7% to produce the'composition of cordierite. X-ray diffraction analysis of the
~solid-state processes combined with optical investigations and differential thermal
a
alysis
n made it possible to interpret the mechanism of dissociation of agalmato-.
.'lite and the reaction of formati.on of cordierite in the solid state. The follow-,
;ing equations represent the processes taking place at 600-13500C:

~cordierites synthesized from glass and pure oxides in the solid phase, with the ex-'
.Caption of the rate, which was faster in the case of agalmatolite. The cordierite

phases on the strei6gth of pyroceramic materials. Z5rlier, this effect was not
studied experimentally and its role in the st engtl4bof pyrocerams was considered
negligible in a theoretical study. Glass formulations were selected on the basis of
their homogeneity and fine cyrstalline structure. Microphotographs:of the same
glass anneAled atdifferent temperatures showed differences in the size, form, and
orientation of the primary dendritic spinel crystals and in the appearance of the
secondary quartz-.like and cordierite/phases. A clear correlation was shown between

was in the pyroceraml5sample with the finest dendritic spinel crystal structure and
interdendritic distribution of cordierite crystals. The increase in strength was
due to the dendritic structure~which rw the most favorable for formation of strong
intercrystalline bonds and for a minimum of crystal defects. The conclusion was

command and execution transducers of the deformation traneducerep
and that the compensation applies only to those of the static and
dynamic friction forces whilh actually exist at the mechanical
linkage after the respective deformation transducers. The experi-
ments carried out with an experimental reversible follow-up sys-
tem show#d that in a manipulator with compensation the most exact-
ing reqipirements have to be made with respect to the spring defor-
mation transducers, one of which is as an exact zeroing as possi-
kle. As a result of many trials a transducer was designed for mea-
suring the deformation with a zero return accuracy 6 < lOw which
corresponds to a change in the to-zero' of the sensing device in
the transducer of � 10 mV. The maximum useful signal from this
element was 2.5 V. Tha sensing element (whose output voltage is
proportional to the deformation of the spring) was a small dimen
sion linear transformer type J7T-386 (LT-386) having a scope

stator of the variable transformer LT-386, whose rotor was tightly
coupled to the shaft. The deformation element was a flat springo- -nt
with regulated tension,which could provide a dead-zone of action
if necessary. Although the linkage cables were replaced by shaft,
the stability of the system was good and corresponded to the spe-
cific requirements. There are 6 figures and 4 Sovie-,,-bloo referen-

Professor T. N. Sokolov at the Department of Mathematical and ATM-
logue Computer Instruments and Equipment of the Leningrad Polyte2h-
nic Institute im. M. I.. Kalinin, of follow-up systems with d.c.
and a.c. motors has shown that a typical circuit as given in the
figure may be used as a criterion of quality for may other cir-
cuits. The analysis is made in the linear plane only, Experlment
has shown that the operation of a high quality syetem is basically
affected by the characteristics of the double internal feedbaok
circuit (output to input of TA 2 and TA 3). This is so because 1ts
instability may result in the instability of the whole system.,eT.C-.

termined analytically for various time constant ratios of the cir-
cuit. The analysis shows that the operation of the system as a
whole is fundamentally affected by the characteristics of the pow-
er amplifier. Of most importance, in particular, is the fact that
in practice the differential equation of the power amplifier is at
least of the third order. This,also results in a limited output
stage velocity feedback which may be applied. It is stated in cor-
elusion that some of the qualitative and quantitative aspects of

TEXT: The present article is a continuation of an earlier
worA, in which the author analyze a system with a heavy negative iner-
t1aless power amplifier and dutpu
t stage feebacks. The case is consi-
dered, in which the power amplifier of the analyzed system is describ-
ed by an approximate linearized equation; the conditions of stability,
of the inner circuits of such a system are reduced to the simplest pos-
sible form, suitable for both qualitative and quantitative assessment
of stability, of properties of these circuits and of the system as a
whole. it is shown that the results obtained previously apply also to
the present case. The relationships obtained are generalized in such a

TITLE: The effect of certain small parameters on the stability of a
typical automatic control system 1 (internal circuit)
PERIODICAL: Izv. Vuz., Priborostroyeniye, v. VI, no. 2, 1963, 14-29
TEXT: In a series of earlier publications Clzv. Vuz., Priborostroyeniye, nos. 1
and 2, 1962, and Trudy LPI im. M. I. Kalinina (Trans. of the Leningrad Polytechnic
Institute imeni M. I. Kalinin), Radiophysics Section, no. 194, 1958-7 the author
discussed problems of the stability of the internal circuit of the class of
systems investigated. There it was shown that apart from "small" parameters of
the power amplifier, the system may contain other, additional sources of inertial
lag. In the present article the author considers the effect of these additional
parameters on the stability of the internal circuit of the systems studied,
attention again being concentrated on establisbilng, the qualitative laws of this
effect. A second problem investigated is the nature of the change in the regions
O.L stability of the internal circuit as a function of the degree of compensation
of the power amplifier for the case where the latter is a dynamoelectric amplifier.

TEXT: The polycondensation of furfuryl alcohol M i;j n aqueous solution
(750C) in the presence of 1-1-5~43 H PO , has been inva ated. The time

needed for forming an emulsion before the start of the';-reaction is
30 min if (1) contains no furfural and if the molar ratio 'of (I) and water,
is 3 : I- Heating is continued for 20 min, producing a polymer with a
Viscosity of 200-250 cp. The introduction of formaldehyde in the reactioj~--
(the molar ratio of (I) and CH 0 being 0.6) increases the rate of thf.

polycondensation (15 min.), as w611 as the viscosity of the polymer

TITLE: Radiometric Titrations by Using 110 Ag Radioactive Isotope
PERIODICAL: Revista de Chimie, 1960, Vol. 11, No. 5, pp. 288 - L>91
TEXT: After a brief Introduction on development and different methods of
titration, the authors present the operation method and the results obtained at
the titration of some anions and cations, by using a titrated solution of silver
nitrate traced with 11OAg. Radiometric titrations with a solution of'silver ni-
trate have been performed before (Refs. 3 and 4), but the establishment of the
titre of the silver nitrate solution has been performed according to the proce-
dure of Mohr or Volhard. The authors worked out a silver nitrate solution with
a very high specific activity and the establishment of the titre has been per- L/
formed radiometrically. The recommended titration excludes the utilization of
an indicator for the deceleration of the equivalent point and some errors con-
nected to the visual observation of the Indicating turn point. The silver ni-
trate solution, which is titrated, is the indicator itself. Potassium iodatewas
used as titrating agent. Sodium chloride can also be used. The reaction is

KI03 + AgNO3-31-AgIO3 + KNO3 and the calculation formula is:
N - T - 107 880
TAg = 0 ~~ (mg),
n - 214,000
in which N is the number of cm3 of added KI03 titrated solution, T is the titrate
of the KI03 solution in mg and n is the cm3 of AgNO3 found in the equivalence.
The titration can be performed either by taking.a known volume of silver nitrate
solution and titrating it with potassium iodate, or vice versa, titrating the
solution with silver nitrate. Operation method, reactives and apparatus are ex-
plained. The authors performed the following titrations with titrated silver
nitrate solution: 1) Radiometric titration of cyanogen is performed classically
by using one of the procedures by Volhard or Liebig (Ref. 7). 2) Radiometric
titration of oxalic ions. 3) Titration of sulfoamides. These methods briefly
described by the authors belong to the isotopic phase of titration. A fourth
method, belonging to the "titration in the non-isotopic phase" is the radiometric
