-like tons as well. The primary
i activated not only with thallium, but with other mercury
purpose was to determine to what degree the mercury-like tons can serve as
"luminescent probes" In the study of different physical phenomena in crystals (for
example, the phenomenon of energy migration), which develop as the result of the effect
of electrons *on the crystals. 7%e author has shown that the mercury-like luminescence
cen ters in these phosphors can easily be excited by an electron beam. The experimental
results clearly show the appearance of activator emission In cathode luminescence of i
the phosphors mentioned above. The spectrum of this emission is very close to (if not
Identical with) the fluorescence spectrum; that is, the emlasion under electron excitation
corresponds to 3 p 1 _+ IS 0 transitions In Ga-~ Ge2+, In+, Sn2+, and Tl+ centers. The
author has examined cathode luminescence spectra as a function of the activator concen-
tration In the surface layer of KI-TI. Possible mechanisms for the cathode lumines-
cence of the phosphors under discussion are considered. "In conclusion, the author
wishes to express her sincere gratitude to Ch. B. Lushchik for proposing the subject
and supervising the work, to N. Ye. Tmshchik for assistance In designing the equipment,
to N. A. Yaanson and 1. A. Muuga for furnishing some of the oboe s of the Investigation,

TOPIC TAGS: hermetic seals metal seal
ABSTRACT: An attempt was made to develop a model for the operation of a contact
metal seal for liquid media. The seal (see Figure 1) consists of two metal surfaces
ground dawn and pressed togetherp having the same microgeometry and width b., and
separating region Al with a liquid under excess pressure p from region Aa with air at
atmospheric pressure. The problem is assumed to be two-dimonsionalp. is e., an the
quantities are indeDendent of the coordinate y (which is perpoudicular to the plane 0
the figure)~ and hence the sealing surfaces are absolutely Aane and coincident. A
theoretical equation is derived expressing the nominal specific pressure qO on the
sealing surfaces necessary for tightness as a function of the pressure of the mediua
p, sealing width bs allowed leakage Q) . viscosity of the medium -1 , microgeometry
parameters of the sealing surfaces r# hm and AAa# and elastic constants of the sealin

Abstract: rived from carbohydrates in as Lauch as zany of
them represent complex asters of glucose and

ic compounds, entering into the composition of
tannio acids of both rroups, is indicatod through
the formation of polyphenols, entering into the
composition of tannic acids from oarbohydratos.
The hypothesis linking the formation of polyphen-
ols with the photosynthesis process has not beon
confirmod, so that the synthesis of tannic acids
in plants can also occur in the absence of lipht.

TITLE: On the Problem of the Reduction of Furfuroiu on the, Mercury

PERIODICALi Zhurnal obshchey khimii, 1959, Vol 29, Nr 1, pp 17-20 (USSR)
ABSTRACTi Taking into account the important part played by furfurole in
industry it is necessary to employ more accurate methods for
its quantitative determination, In this connection the
polarographic method gains importance, especially because of
contradictory data published about it. (Refs 1,2,5). The
author is of the opinion that this is due to the different
conditions of furfurole polarographing. It is the aim of the
present paper to investigate the stepwise reduction, to
determine the intensity of diffuslon current, the importance
of the furfurole half-wave potential to be found in dependence
on the aqueous or aqueous-alcoholic medium, the composition.of
the mixture and the percentage content. The above-mentioned.
reaction was found to take place in two steps in a certain,~
interval of the percentages. The percentages of the mixture

as well as upon the half-wave potential. At pH)7 only one
polarographio wave appears clearly which renders it possible
to determine the diffusion current. It is, therefore, con-
venient to carry out the quantitative polarographic determina-
tion of fuzfurole in alkali medium, especially because in such
a medium sodium sulfite can be used to eliminate oxygen. In
the aqueous alcoholic medium the intensity of the diffusion
current of furfurole is smaller, the half-wave potential
more negative than in aqueous solutions. With an increase of
the concentration of the alcohol the wave height decreases,
whereas the absolute intensity of the half-wave potential
increases. There are 2 tables and 3 references, 2 of which
are Soviet.

;The article is a direct continuation of a previously'published paper (N.A.
,Elango, Trudy IPA AN ESSR, #2- 12, 197, 1960). It was established that the
~iX-ray induced growth of the number of electronic (F) and hole (V2) centers
!occurs in two stages. The first# rapid stageldepends on the pre-excitation
'number of vacancies in 'the crystal, the-secondt linear stage depends on the

ystal. The ratio of the number of
lV2-centers to-that of F-centers increases with excitation time. It was
Ishown that the greater the point defect number in the crystal prior to ex-
Icitation, the lower is the thermal stability of the X-ray induced centers in
~it. This effect is connected with the ionic mechanism of the thermal de-
Istruction of color centers. The mechanism of oreation of color centers by
IX-rays is discussed. Ch.B,Luchchik is thanked for help rendered..' There are

TEXT: The ionic conductivities of a number of single crystals
of NaCl containing different ntimbers of host and aimpurity defects
are measured in the temperature range 20 to 200 C.. The crystals
are 1 mm thick and aquadag electrodes 10 MM2 are used. It is
shown that the smallest ionic conductivity is obtained for the
natural crystal and that the ionic con .ductivities for crystals..
grown from a melt decrease with increase of their purity. The
largest value obtained is for NaCl containing 0.1 mole % Ca.
Conductivities are in the region of 10-10 11-1 cm-1. Samples
with large ionic conductivity have low thermal stability for
F centres created by X-rays (Cu anode 55 kV 20 mA) and a larger

X-irradiation. These results confirm the hypothesis of the
ionic mechanism of the thermal destruction of F centres in alkali
halide crystals. Ionic conductivity of natural rock salt has a
maximum in the temperature range 6o _ 80 *C after X-irradiation
and partial optical bleaching of the saw-le. 'This maximum

ABSTRACT: The present communication is a direct continuation of a
cycle of investigations carried out by their laboratory to clarify
the mechanism whereby ionic crystals become colored by ultraviolet
radiation, x-rays, and radiation from reactors. Natural crystals
of NaCl and crystals of NaCl.T1 and KC1.Ag grown from melts of

(60keV), slow electrons (150 eV), and ultraviolet 'radiation (5--14
eV). The authors were especially interested in elementary processes
which occur during a complicated phenomenon such as radiation color-
ing of ionic crystals, and paid consequently special attention to
a parallel investigation of the production of F centers by these
type of radiations. It is shown that irradiation of the crystals
leads not only to a filling of the anion vacancies by electrons,
but also to generation of a large number of new point defects and
their clustering. Only the electron-hole mechanism of F-c(--z*iter
production is considered in detail, the others having been treated
by the authors in numerous other papers. It is pointed out, how-
ever, that this is not the only possible mechanism. "WP ar(i deeply

ABSTRACT: The authors have made a detailed Investigation of the tem--
perature dependence of the efficiency with which F centers are pro-
'duced by x rays in NaCl, KC1, KBr, and KI during the first stage of
adiative coloring, in the temperature interval from 8o to 450K,
which covers the region of autolocalization of the holes (100--250K)

iand:of intense ionic processes in crystals (300--400K). The crystals~
;were grown from the melt by the Kiropoulos method. All were of
:equal thickness (0.75 � 0.10 mm) and were irradiated In a cryostat
:sunder identical conditions. The absorption was measured automatically
,during the irradiation of the crystals at the wavelength corre3ponding
;to the maximum of the absorption F band. All crystals had an optimal,
~temperature at which the efficiency of F-center production was a
!maximum. This temperature decreased in the sequence NaCl--KC1--KBr-
;KI, and agreed well with the temperature at which intense autolocal-
.ization of the holes in the crystal lattice took place. At the opti-
~mal temperature, the F centers were produced more effectively in
NaC1 and K01 than in KBr and K1. This difference is connected with
.the difference in the relative efficiency of generation of electron-
,hole pairs and excitons in the different ionic crystals. The authors
I
iialso measured the tbemolumineseence of the crystals after x-irradia-.
at 80K for five minutes, and the temperature dependence of the
,x-ray luminescence as the crystals were cooled from room temperature.
Two thermQlumineseence peaks were observed in the region of steep
decrease of the F-center efficiency, due most probably to the release

stage of the radiative coloring the F centers are produced essentially.
via the electron-hole mechanisms the efficiency of which is deter-
mined in many respects by the conditions for localization of the ho3as
-and the different points of the crystal lattice. Authors are grate-

TITLE: Rubber Caulking for Warping Seams in Canal Linings
PERIODICAL: Gidrotekhnicheskoye stroitel'stvo, 1959, Nr 7, pp 18
- 22 (USSR)
ABSTRACT: The process described is one applied in this case to
the Noith Donets-Donbass canal, which is lined with
sectional ferro-concrete sheets, with provision for
draining (Fig 1). In view of the necessity for good
draining, the caulking of the concrete sheets is of
extreme importance, and the use of rubber for this
purpose, for the first time in the USSR but common
now in many countries, has proved to be preferable
due to its durability, flexibility, cheapness and its
waterproof properties. Vig 2 shows, the tapered ed e
of the concrete sheets and the 7x2 cm. recesses cuf
into them, into which 2mm thick rubber strips are af-
fixed by means of an adhesive and sealed with a me-
tal-reinforced sand/cement mixture. Three alterna-
tive methods of sealing are given, all of which pro-
Card 113 ved to be unsuited for the purpose. The width of
