Laboratory of the Chemistry of Metallic Alloys of the InAltute, of~Metilluigy im.
A. A. Baykov, anew, eight-component, high-strength weldable titanium alloy AT13
has been developed. The alloy liquidus and solidus temodratures'were found to, be
1800 and 1675C, respectively. The alloy structure consists mainly of the 'a-ph'ase
with a very insignificant amount of the 0-phase. The 640jrah6f6rmation occurs in
the 1030-1050C range; no other transformation occurs in the 100 1000C range. At
room temperature, AT13 alloy has a tensile strength of 127.1 129 kg/mm2, a yield

ABSTRACT: The electrical resistanc of alloys of the TI-Nb-~Cr system was Investi-
gated as a function of their chemical and phase composition at room temperature.and
during beating to 11000C. The thermal expansion In the 20-IIOOOC range was also
studied. The alloys were first quenched from 10000C and subjected to prolonged
annealing. Data on the variation of the electricalresistance with the composition
were found to be In good agreement with the results of microstructural and x-ray
phase analyses. The electrical resistance data for the 20,41000C range permitte&
the determination of the temperature boundaries of existence of the phase regions.

The Synthesis of Rutin (Sintez rutina)
PERIODICALt Doklady Akademil nauk SSSR, 1958, Vol 1,23, Nr 2, pp 305-307
(USSR)
ABSTRACT; Rutin, or quereetin-3-Ilrutinosidell (VII), is the active sub-
stance of vitamin P. The importance of'rutin is great,:as
(besides other substances) it can decrease the permeability
and fragility of the capillaries (especially with ascorbic
acid). As quercetin (V) has 5 hydroxyl,groups in the molecule
its production from its 3_'gldcosides i's very difficult. Be-
sides, there are some more difficulties.,(Refs 1-4) so that the
synthesis of rutin or other quereetin-3-disaccharictes remained
unknown until recently. The authors de~scrib~e the synthesis of,
rutin from quercetin and acetobromo rutinose (see Scheme). The
initial quercetin was synthesized according to reference.6,
however, with the difference that the:protection of the
hydroxyl group in the vanillic acid was obtained bybenzyla-
tion: triethylamine (Ref-7) was used as a condensing agent.

a-acetobromo-rutinose was synthesized according to reference 8
from acetobromo-rhamnose and acetochloroglucose. The results
of the paper chromatography, and'the comparison of the ultra-
violet absorption spectra (Fig*,l)-showed a complete identity
of synthesized and natural rutin..As querDetin-under the in-
fluence of liquid ammonia partly decomposes admixtures with an
ultraviolet absorption maximum occur in the chromatograms of
synthoti'd rutin; these admixtures,characte-rize*the quercetin
de6omposition products. The rutin synthesis mentioned above is
the" final stage of its complete synthesis. An experimental
part with the usual data follows. There.are 2 figures and

ABSTRACT: The saturation vapor pressure of thallium chloride was,-de-
termined according to two methods: the method,of boiling,points,
and the method of saturated current (method potoka nasyshchez Iiiya).
The use of these two methods made it possible to cover a great
temperature range and after analysis of the results obtained
to draw conclusions on the molecular state OfL thallium chloride.
The apparatus for the determination of the vapor pressure
according to the boiling point method is shown in a scheme
and is discussed briefly. Three experimental series were carried
out; the results obtained are given in tables and are made use
of in the accompanying diagrams. An appara tUS Lbuilt according
to the instructions of Gerasimov, Dreving an&Komandiin (Ref'5)

disperse Materials
PERIODICAL: Inzhenerno-fizicheskiy zhurnal, 1959, Nr 9, pp 92-96 '(USSR)
ABSTRACr-, The authors,consider the processes of pseudo-fluidizati on of granular
materials and give formula for determining the point~of transition of a
monodisperse layer Into the state of fluidized bed, Formula 1. Making
onkov ZR-efs 1,2 for the coeffle'lent
use of the expression given by Zhavor 7
of resistance of a granular layer to gas blowing. and~of the critical-
ations proposed by Kasatkin and Akopyan ZRef 37 ax.id Todes and Bondareva
Ruef g, the authors obtain criterial equationslof pseudo-fluidization,
?
Formulae 6, 7 and 8, not only for laminar processes but also for the values
of Re up to 1,000. The experimental checking of these formulae on the mono-
disperse layers of z1hc concentrate cinder, mercury.oreand quartz sand
showed that differences between the calculated..and experimental da:ta did
not exceed 5%. The transition of a 'polydisperse layer into the.state of
fluidized bed differs essentially from that of,,a monodisperse layer. How-

TEXT. The authors studied the effect of Co. gamma,ratiiation (dose
6 6
varying from 1.10 to 18.2-10 r) upon thestrength.of starch gelatins.
Potato starch with a moisture content of 16.6% was used for the, experiment.
After irradiation in glass ampoules, gelatins containin '.12% of di-
g _ j
starch were produced, and the limiting shearing stress Pm-was, determined
by means of a plastometer. Fig. 1 shows P as a function of time and
m
Fig. 2 Fm as a function of the dose.,The ionizing radiation first caused
an increase in Pm~ then a reduction growing in proportion-with the in-
6 :2
creasing dose, so that at 7.1-10 r~ Pm, amounted to 3 g1cm only,~ and;

at 16.2-10 r no gelatin formed any more. The course.of the curve
Pm - f(D) (Fig.2) which passes through a maximum., is determined by the
change of the number of hydroxyl groups available for the formation of
hydrogen bridges. First, radiation effects depolymerizatian. Thus3
screened off OH groups are set free; which form additional hydrogen
bridges and increase P.. Then, the OH groups area however,. split off'
under the formation of gaseous products. Assuming & direct,propor-
tiona.lity between Pm and the number of H bridges, the autliors write
