ABSTRACT: The study of the kinetics of spherulite formation was carried out in con-
nPction wth the study of the formation of spherulite structure in glasses. The
ch .r. th radius of a spherulite in time was investigated at a fixed crystalliza~
tirngem
1~era%re and a graph was constructed for the rate of growth of spherulites as
a fu-nction of crystallization temperature. Investigations were carried out with sphe-
rulites formed in glasses of the following composi tion: Li20--l.25%, %0-10.05%,
PgO-17.95%; A1263--8-99%, SiO2--61.76% and Li20-19.76%, Si02--80.24%. For each com-
position of glass, a series of specimens crystallized at the same temperature but with
different holding time were made. Each glass specimen was tempered in air after heat
treatment. A polished face of the crystallized specimen was etched in 10% acid in or-
der to develop the structure. The radii of spherulites werq measured with a MBI-6

microscope with 100 x magnification by means of an ocular micrometer. At least three
measurements were made for each spherulite. It was determined that the gmwth of
spherulites under isothermal conditions proceeds with constant radial v elocity. In the
inItial moments of the crystallization process, inhomogeneity regions developed in the
gl6ss are observed under an electron microscope in the form of drop-like particles.
Thl composition of these regions is apparently close to the composition of the future
crystalline phase. The growth of spherulites proceeds by the addition of structural
el9ments of the structural material of crystal and rejection of impurity elements. It
is!'believed that the growth of spherulites is not determined by the addition of indi-
vidual ions or atoms, but by their complexes. Orig. art. has: 2 tables, 4 figures.

ABSTRACT: The article describes the formation of spherulites as observed in four dif-
ferent silicate glasses of nonstoichiometric compositions. After heat treatment, spe-
cimens were studied by means of an EM-5 electron microscope at 20,000-40,000 x magnIfi
cation. Coarse-structured specimens were studied by means of an 14BI-6 optical micro-
scope at 400-800 x magnification. The study of the formation of spberulites was con-
ducted by freezing the crystallization process at some definite stage. Glass speci-
mens were heated at 600, 700, 800, 900, 1000 and 11000C for periods ranging from seve-
ral min to 4 hr. Each specimen was heated only once by placing it into a furnace pre-
heated to the desired temperature and upon expiration of the desired exposure time, it
was air quenched. It was found that the spherulite formation process is preceded by

the formation of 0.05-0.07 p particles or needle-like crystals 1-2 P in size. The
formation of spherulites in the investigated silicate glasses is similar to the forma-
tion of spherulites in polymers and minerals. The formation of spherulites takes
place by the following three mechanisms: 1) from the concentration ofective centers
or microcrystals produced in the initial stage of the crystallizationqro6ess by the
geometric selection process; 2) during growth of disoriented crystallization centers
on particles of some substratum; and 3) by the splitting of single crystals. Orig.

,V,STRACT,# Samples of ground Piuscovite were fired at 6oo-i4oooc at 500 intervals for
3 hr at each temperature and the products formed wore analyzed by optical oxmiiination,
x-ray diffractiong differential thermal analysis, and Infrared spectroscopy. The
first structural changes were observed at 7000C. Thermal -treatment at 1OOO0C was as-
sociated with the broakdmm of the structure and with amorphization. The formation of
now ar7stalline phases occurred attemperatures above i0000C. The following compounds
were identified by x-ray diffractions y-A120~, spinel MgA12%, .9anidine,
K20*A12(~-63ic~2, a-A1203 (corundwii). On the basis of the infrared spectra of musco-
vite samples subjected to different temperatures, a quantitative description of the
decomposition process of mica Is proposed (see Fig. 1). Authors are Grateful to G. F.
Stavitskaya, who took the IR spectra. Orig. art. gas: 6 figures and 1 table.

ABSTRACT: The effect of temperature on formation and recrystallization of quartz-
like phases during the crystallization of K-1 to K-9 glasse .th rious silicaand
titanium dioxide contents was studied. The individual oxi V omponent in glass/'sam-
pies was (in wt %) 27.69 to 42.02 for A1203, from 10.96-t6 16.63 for ffgU_,_=4. 5 to
61.35 for Si02, and from 0 to 15.0 for Ti02. The glass samples (K-1 to K-9) of
various compositions were prepared by fusing mixtures of oxides in platinum cruci-
bles at 15500C for 4 hrs. The glass samples were subjected to thermal differential

and x-ray analysis. It was found that an increase in Si02 content in glass leads to
increased thermal stability of the quartzlike phase. Low Si02 content is reflected~
in low content of the quartzlike phases. No quartzlike phase could be detected by
,x-ray analysis for glasses containing 41.35 wt % Si02- Introduction of Ti02 to
glasses resulted in greater contents of quartzlike phases and in an extension of the
1ower limit of these phases to 800-8501C (while for Ti02-free glasses this lower
limit was equal to 10000C). Orig. art. has: 3 figures and 2 tables.

-.ABSTRACT: Amicrophotographic study has been made of the crystal phases formed at
differe9t crystallization (annealing) temperatures in magnesium aluminosilicate
glassesPof different composition to ascertain the effect of morphology of crystal
phases on the strength of pyroceramic materials. Eylier, this effect was not
studied experimentally and its role in the strengtI4 of pyrocerams was considered
negligible in a theoretical study. Glass formulations were selected on-the basis ofL
their homogeneity and fine cyrstalline structure. Microphotographn;of the same
glass anneAled at -different temperatures show-ed-differences- in the size, form, and-
orientation of the primary dendritic spinel crystals and in the appearance of th:
secondary quartz-like and cordierite/phases. A clear correlation was shown betw en

microhardness, As a measure of strength of crystallized glass, and morpholog of the
crystals. Tabulated data showed that the highest microbardness (1400 kg/mm
was in the 2yrocera %ample with the finest dendritic spinel crystal structure and
interdendritic distribution of cordierite crystals. The increase in strength was
due to the dendritic structure~wbich was the most favorable for formation of strong
intercrystalline bonds and for a minimum of crystal defects. The conclusion was
made that the morphology of the crystals is one of the main factors of developmqnt
,of high-strength pyroceramic materials. Orig. art. has: 2 figures and 1 table. JJK'

ABSTRACT: The authors studied the regions of vitrification and sequence and
character of crystalli7ation 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 ciystalline phases as
a function of temperature and composition was-studied. Ir samples containing

of thermal, x-ray diffraction, microscopic, and crystal optical analyses. The
system is found to have six chemical compounds with BaO:GeO2 ratios equal to
3:1j 2:1, 3:2, l:lj 1:49 and 1:19; three of these compound3were obtained for the
first time: Ba3GeO5, Ba.3GeZO7,and BaGe19039. An approximate scheme of.the

TOPICTAGS: pattern recognition, Booleanspace, automatic machine teaching, algorithm
A13STRACT: As one of the ways of solving the problem of pattern recognition and teaching of
pattern recognition deserving of attention, the authors Investigate appropriate models In
Boolean space. The following Is assumed as a working hypothesis: the pattern is a Boolean
function having a sufficiently simple disjunctive form, 1. e,, with a small number of low-rank
conjunction.s. In this case it becomes possible to teach pattern recogn!tlon on the basis of
relatively short teaching sequences, the length of which is appreciably less than the power of
the set. Under these conditions effective algorithms of teaching pattern recognition are con-
structed on the basis of methods of minimizing weakly determined Boolean functions. For
example, the use of the following principle Is reasonable: for a given teaching sequence of

fixed length It is assumed that the pattern corresponds to a Boolean function having the simp]
disjunctive form (minimal or briefest) and taking from the elements of the teaching sequence
the values prescribed by this sequence. By Increasing the fixed length and forming a corre-
sponding sequence of Boolean functions It Is possible to expect that with a sufficiently simple
pattern this sequence will converge at a certain limit corresponding to the pattern sought.

binary elements whose states can be described by a 10-digit binary word
C - (CIO R cl , . . . , C, ). Under the influence of control pulses at the generator
input, the word c will consecutively take on all values that correspond to all
possible combinations of k ones and 10-k zeros. The field unit comprises one
principal and 13 auxiliary fields. Each field comprises Z' a 1024 elements with
numbers j, where j a 0, 1, .... 1023. Block diagrams of the above units are
shown, and their operations are briefly described. Orig. art. has: 4 figures,
