This work has both theoretical and practical value. The dependence of the heat of
wetting of silica gel by water, on the quantity of previously adsorbed -water, was
measured on a homogeneous, coarsely porous silica gel made from SiCl and having
a known specific surface. Results of the measurements established the abs decendence
of the heat of wetting by water and the differential heat of adsorption of the water
irapor on amount of water adsorbed per unit of surface. The differential heat of ad-
,:orption of water vapor decreases in proportion to the increase in the degree of
filling of the surface.

Abstract : A glass instrument war develor~ed --r'or determining the surface
tension CK and the density V of liquid metals in a vacuum. The
instrument is suitable for temperatures to 5500. The accuracy
in the determination of ? is 0.2'j", that of C-Z is approximately
1%~. The value of 9 is determined by measuring the height
of a column of the investigated liquid required to balance
a known gas pressure (H.). The value ofC~' is determined from
the maxJmum pressure of th(, column of the investigated liquid,
corresponding to the encape of a drop from a capillary stub.
The value of CKwas moasured for refinod tin at 250 -- 5500;
the effec+.L or impurities contained in commercial tin of "02"
grade onC~( were established. The values of ~ for aommercial
and refined tin were measured at the seine temperatures.

(USSR)
ABSTRACT: Experimental data are given which characterise the phase
transformations and structural properties of the polyesters
obtained from aliphatic dicarboxylic acids and glycol.
To elucidate the phase states of the polymers, thermal,
thermographic, X-ray and microscopic methods of analysis
have been applied, supplemented by the calorimetric
determination of the latent heot of crystallisation of the
polyesters. X-ray data confirmed the existence of long
range or-der and crystal-optical studies showed that,
depending on their rhemical structures, polyesters
crystall1se as spherulites of two types. The polyesters
ifere oDtained by the direct condensation, without catalysts,
of tile poly-inethylene series of acids, from succinic to
sebacle, with various glycols. In appearance, the polyi:iers

uras s'udied. It was established that grinding the prep-,
arations at the time of crystallisation did not eliminaTe
the spherulites but promoted the formation of more and
finer spherulites which occurred in chains. The reasons
for spherulite formation are still obscure and must be
examined further as they are of great importance.

TITLE: The Investigation of Adsorption Layers on the
Liquid Metal Surface
PERIODICAL; Doklady Akademii nauk SSSR, 1959, Vol 128, Nr 6, pp 1228 1231
(USSR)
ABSTRACT: A survey of relevant papers is given as an introduction: on the
surface activity of alkali metals on liquid 9g, Sn, Pb, and Bi
(Ref 1), furthermore Te on Sn (Refs 2,3), S on Cu (Ref 4),
0 and S on Fe (Ref 5). The authors investigated the surface ten-
sion 6 of thaliium and antimony on liquid tin. 5n had been p4ri-
fied by means of zone malting and contained less than 1.10_-')~
by weight of impurities. TI and Sb had a degree of purity of
99*99%. The surface tension of the Tl solutions in Sn was in-
vestigated at temperatures between 270 and 4000 and a Tl con-
centration of 0.18-1.96 at %. Figure I shows the function
6 - f(K) (N - T1 concentration). The isothermal lines approach
each other as N increases, and at 1.96 at % of TI the tempera-
ture factor K of the surface tension equals zero. The foothermal

oped by Shishkovskiy. The surface activity G 0 of the TI dis-
solved in tin decreases as the temperature increases. The sur-
face tension of the solution of antimony in tin was investigated
at a 3b content of between 0-5-5.90 at ~ and tomperatures of
300-4500 (Fig 2). The linear course of the a isothermal lines
is remarkable. The adsorption r of Tl and Sb on the surface of
liquid S?v7as calculated according to the Gibbs equation. The
curves P . f(N) for Tl - Sn are also contained in figure 1,
and for Sb - Sn in figure 2. From the adsorption of Tl and 3b
the area covered by one atom of the said elements on the sur-
face of liquid tin was calculated. As is shown in figure 3, the
calculated values lie along the ideal isothermal line of a
gaseous two-dimensional layer, the course of which is deter-
mined by the equation no - kT (n - surfaco tension in dyn/cm,
W a area of one atom of Tl or Sb on the Sa in V ). The adsorp-
tion heats calculated for Bi, Tl, Sb on the surface of liquid
Sn correspond as to their order of magnitude to the values for
the adsorption of gases and vapors on solid surfaces ( Ref 12).

TEXT: The effect of indium and germanium admixtures on the surface ten-
sion d of tin was examined, as In and Ge show a similar value of d as
tin, possess different melting temperatures, and are soluble in li uid
and solid tin (Table, physicochemical properties of In, Go, and Sn~.
The surface tension was determined by the capillary method. The value d
was measured on two tin samples in the temperature range from 250-5000C.
i.e., on tin purified by zone melting, and on tin purified by long heat-
ing at IOOOOC in vacuo. Both samples showed the same d value within the
limits of the error in measurement. The surface tension of Sn - In
solutions was determined in the temperature range 250-4500C with additi.ons

of 0.34 to 2.42 at% In, and the Sn - Ge system at 400-500'C with addi-
tions of from 0.5 to 2 at% Ge. It was established that In and Ge do not
change the surface tension of tin. Tests on the microstructure of
alloys and crystallization kinetics with additions of from 0.005 to
'L
0-05 at% Ge or In showed that these quantities of admixtures do not
alter the structure of the tin, whilst additions of from 0.4 at%
strongly affect the dispersion degree of tin. Germanium refines the tin
structure to the same degree by crystallization by rapid or slow cooling,
whilst with In admixtures, the effect on the structure of tin depends
on the rate of cooling. With a cooling rate of 0.70C per minute, a coarse
structure is obtained, and with a rate of 70C per minute, a fine one.

TITLE- The effect of sodium and zinc additions on the

PERIODICAL- Fizi.ka metallov i metall.ovedeniye. v. 12. no. 5~,
1961, 7o8 - 713
TEXT. One of the methods of refining the structure of
metals consists of adding a small quantity of a suitable,
so-called, modifying alloying constituent. In studies of the
modifying effect of various additions, it is important to use
high-purity metals,to ensure chemical and thermal stability of
the moulds and to prepare the experimental alloys by vacuum-.
melting, All these conditions are easier to meet for low-
melting point metals and it was for this reason that tin was
selected as being particularly suitable for the purpose of
the present investigation, whose object was to study the effect
of a surface-active (Na) and a surface-inactive (Zn) metal
on the structure and microhardness of zone.-refined high-plarity
(99.9992?~) tin. The experimental specimens, containing

methods were used in the preparation of metallographic specimens.
In one. the surface of cast metal was filed with a barette file
and polished with a velvet cloth covered with a special paste
recommended i.n Ref- 5 (Metall., 1952, 17/18, 528), In the
ser,ond aietbod a liquid alloy was poured in vacuum through a
capillary into a cylindrical gl.ass mould, at the bottom of which
a flat polished optical glass disc had been placed. Aft er
solidification, the flat end of the cylindrical ingot in
contact with the polished glass disc had a iiurror !,-.urface i,~Iiich

solidification and acts as a grain-refining addition. The
effect of Zn is much less pronounced.
2) The effect of the additions studied on the degree of
dispersion of the structure of the surface layer, plastically
deformed and recrystallized during mechanical polishinm., is
different. In this case Zn is the more active addition, which
can be attributed to the fact that Zn, being soluble in Sn,
raises it--:; recrystallizat-ion temperature. It is also for the
same reason that the hardness of Sn, unaffected by Na additions,
increases with increasing Zn content. This is shown by data
reproduced in atable. where the microhardness values of various
alloys, tested under a load of 30 %.-. are given: the mi-crohardness
of pureSn being H = 6.2 1-zglcm2.
3) The grain growth in the surface 1'.qLyer. plastically deformed
during polishing and subsequently annealed for 3 hours at

Zn additions.

ABSTRACT: The kinetics of the grain growth of Sn in the presence of small
concentrations (0. 001-0. 5 at Jo) of surface-active (Na, Bi, Sb, TI), surface
neutral 4n, Ag), and surface-active (Zn) impurities are studied. A certain
parallelism has been found in the influence of these impurities on the surface
tension of molten Sn, at the interface with the vacuum, and on the rate of grain

growth V. For Bi, TI, Sb, and In, the following linear dependence holds well:
. ig V;-A'g(CV-rO)H P where c-impurities in at.jo concentration; and
r and ro-the atomic radii of P and Sn impurities. Noticeable deviations from
linearity are observed for other impurities, and may be explained in some cases
by the very small solubility of the impurities (Na, Ag), and in other cases by the
non-activity of the impurities (Zn). It is determined that all impurities studied
greatly increase the activation energy of the grain growth of Sn. B. Summ.

ABSTRACT; The surface tension a of the Sn-Bi (14 alloys) and Sn-Pb
(13 alloys) systems has been investigated by the gravitational method. The
isotherms and po~ytherms obtained did not show extreme or bend points. The
eutectic fields of both systems were carefully analyzed. The study of the relation

ABSTRACT: Two groups of workers composed of 995 male metal workers and machine tool
workers a-es 17 to 55 yrs were investigated to determine the effect of machine shcp
noises on blood pressure. The first group (508 workers) was exposed to medium
frequency noise of 80 to 85 db intensity, and the second group (487 workers) was
exposed to high frequency noise of 90 to 95 db intensity. Blood pressr-re was
measured before and during the work shifts and evaluated according to Ya. A. Rosin's
system In which the systolic and diastolic pressures are considered as parts of the
same process. ECG data were recorded for 71 persons ages 20 to 40 yrs of the fi--st
group and 113 persons of ages 20 to 40 yrs the second group. Study data shorw that

the blood pressure of' subjects in the second group (90 to 95 &.b) devia-.6s more
frequently from the norm; statiscally reliable results were established for ages 21
to 30 yrs and 31 to 4.0 yrs. In the second group, su]bjects ages 17 to 20 yrs displayed
-J
mostly low blood pressure (hypotonia and diastolic hypotonia and subjects ages 41 to
55 yrs displayed mostly high blood pressure (systolic hypertension and hypertonic
disease). For the second group, the mean systolic pressure value for subjects ages
17 to 30 yrs was 4 to 5 mm lower than the norm, and for subjects ages 31 to 55 yrs
was 3 to 4 mm higher than the norm. In the second group, the diastolic prossuros of
all age groups did not differ significantly from those working under relatively quiet
conditions. ECG data showed that the heart contraction frequency of subjects ages
20 to 40 yrs of the second group is marked by greater deviations, both higIner and
lower. The author concludes that the blood pressure of persons exposed to more
intense. noise is si*iject to more expressed fluctuations. Orig. art. has: 2 tables.

ABSTRACT: The authors present a study on materials for impregnation of
hydraulic engineering concrete structures. Prefabricated
reinforced concrete structures are especially considered.
The results of these studies are given in graph form. Syn-
thetic materials such as styrolmonomer and metacrylate were
proposed as insulating agents, but they were too expensive,
toxic and inflammable. Bitumens BN-III and BN-IV were
tested as soaking-impregnation materials. They proved to
be unsuitable because of their high viscosity. The BN-II,
BN-I and BN-C; bitumens, as well as paraffin, ozokerite and

Glucose serves as a nutrient for.erythrocytes in
preserved blood, but increases their vol (a
phenomenon which leads to hemolysis). Sucrose does
not act as a nutrient, but counteracts the harm-','
ful effect of glucose by preserving the size and
shape of erythrocytes. Expts showed that addn of
both glucose and sucrose to citrate used for

preservation of blood delays hemolysis by a period
Of 10-15 days as compared with other hydrocarbon
preservatives. In testing the quality of blood, the
