ABSTRACT: Laser engineering requires coatings possessing high reflec-
tion coefficients, good stability, and resistance to high-density
electromagnetic radiation~* Traditionally, the dielectric mirrors used
in lasers have been made from zinc sulfide and cryolite. The present
article deals with an investigation of multilayer dielectric mirrors
made from lead monoxide and cryolite with a view to determining whether
such mirrors, which are easier to produce than the zinc sulfide type,
Can$ be successfully employed in lasers. Specially purified lead
monoxide was used in producing layers with minimum absorption. The
optical characteristics (reflection, transmission, and absorption-R,
T, and A, reapectively) of the mirrors were then measured by an'instal-

Abstract The diagram of state of LM-NAC1401 was investigated by the visual-
polythermic method. The chlorides of Li and Na form the compound LiCl-
NaCl, vhich melts and decomposes at 5750. In the double system LiCl-
NaCl, the eutectic point LiCl + LiCl. NaCl corresponds to 5530 and 78.5
molar pexvpnt LiCl, and the transition point corresponds to 5750 and
67 molar percent of LiCl. A transformation of L01 of the second kind
was observed at 5650 and 81.5~ LiCl. The LiCl M salts form A, dimple
eutectic system, vhile the NaCl and R01 salts form a system with a con-
tinuous'series of solid solutions in a minimum.melting temperature at
658o and 50% of the components. The triple system can be subdivided into
tvo subsystems LaCl. NaCl-LiCl-KC1 with a eutectic point at 346o, 55%

ABSTRACT: The ternary systems of Li-, Ha- and potassium sulfate and the
quaternary systems Li,-i7a, KJJC1, SO 4 were investigated in an
earlier paper (Ref 1). It was found that the decay of the con-
tinuous solid solutions of sodium- and poiassium sulfate is
accompanied by the formation of three independent phases of
double salts, which are formed if the temperature drops to
6860-7360. The present paper supplies data concerning newly
investigated cross sections and a final diagram of the entire
system. Figure 1 shows the melting curve in the diagonal
section K 2Cl 2 -Na2so 4* 20 internal cross sections, their cross
sections and melting temperatures were investigated (Figs 1,2).

ABSTRACT: It proved that the complex formation between salts is much
richer and more manifold in meltint.,rs than it is in the aqueous
Solutions of the same salts. The latter fact is due to a con-
siderable hydration of the salts which, in many casest is
stronger than the complex formation (figure 1 shows the melt-
ability diagram of the complex mentioned in the title). Only
one compound of the Na and K sulphates (frequently found in
deposits of potassium sulphate) could be found: Na, K 3(SO 4)2
called glaserite. If water is absent, there exists also a com-
pound which develops during the decomposition of solid solu-

These solid solutionag however, decompose in the ternary system
of Li, Na, K11304 at a temperature reduced to 784-8160, and
form 3 compounds. Neither was it possible'to find their exact
oomposition or to prove the identity of a compound with one
of them (stable below~4760). The decomposition temperature
of1hese solid solutions is,however, reduced by the presence
of the chlorides of the same elements. The thermodynamic con-
ditions are of greatest importance for the complex formation,
especially in the presence of other components in the liquid
phase. All this proves the great importance of medium and
solvent for th,: ,complex formation. The investigation of
meltings of Vae systp-s mentioned in the title (Pig 1)(Refs 1-9)
proved 17 complex compounds. Five of them are double salts.
The different phases are graphically represented in the areas
of a trihedral prism (Fig 2). Three phases develop [ 13, [If] 9

More than 8,000 points of the crystallizing tempe'katures were
determined for the complete investigati ion of the meltability

data, complete investigations of the melting diagrams of 24
cross sections (triangular and squate) through the prism were
carried out. Figure 3 shows the mentioned diagram of a verti~,

of these cross sections 4 phasescould be found: [14 N,

known. There is no isomorphism between the salts of Li and Na in the
quaternary system under consideration. Both the sulfates and the chlorides
form double-salt complex compounds. The action of the medium upon the
formation of complex compounds consists in that the introduction of
chlorides of Li, Nav K into the melt of*the sulfates of these elements
facilitates crystallization from the pure sulfate melt. The guiding ac-

was furthermore ascertained. The authors refer to M. A. Xlochko (Ref, 8)

TEXTs The solubility of LiCl and LiCl + KC1 in H2 0 was studied between
the freezing point of the systems and +250C and the equilibrium diagram of
the ternary LiCl - KC1 - H20 system was constructed. The temperatures
were established at which crystallization sets in on cooling and disappears
on heating of the crystalline phase. The initial chemically pure sub-

ABSTRACT:. An experimental investigation of the effect of 1. 2 mc and 2. 2 mc
treatment of NLKFI-R 400-micron emulsion upon spurious scattering is repo;tel.
Emulsions irradiated in ITEF by 1. 7 -Gev protons were tested. The total length,
of the measured tracks exceeded 1. 5 m. The measured average values of second
differences (MBI-8M microscope, 250 cell) showed that the ultrasonica.Uy-treated
emulsion had a spurious scattering considerably lower than the untreated
emulsion. "In conclusion, the author is deeply grateful to A. L Alikhanyar, for

The authors investigated flotation of Ti-Zr sands of three deposits
in a labora:tory, and partially under industrial conditions. The basic mineral
products of the deposits are: Ilmenite, rutile, leucoxene, zircon; the sands of
one of the deposits contain a considerable amount of alumosilicates. In the sands
the ore mineral grains are finer than the dead rocR (quartz). The sands can be well
washed. The content of slime particles in the sands-is on the average 15 - 20%.
Tests were made with oleic acid, sulfate soap, soap-naphtha,soapstock, tall oil,
oxidized petrolatum,14M -11 (IM-11) alkylsulfate etc. Tall oil is the most effec-
tive reagent. The investigations show the satisfactory.flotability of the whole
complex of heavy minerals. Highest flotation activity is shown by alumosilicates
azd zircon, and least by ilmenite and leucoxene. The selection of a collector is
determined by its cost, availability, stability of properties, toxicity and.by the

results in basic flotation were obtained with sulfate soap at 6 k&/t consumption.
In this case extraction of Zr02 was 97.3% and of TiO2 94.04% of the initial ore.

ABSTRAM The management of the Rostov-na-Donu long distance telephone
exchange made efforts to increase the profit of the enter-
prise. Coin telephones were installed in the town area,
and by a reorganization, it was possible to handle 8tQOO
telephone calls with the same number of operators as in
1956, when 6,500 calls were processed. A number of defi-
ciencies must still be eliminated. The employees of the
telephone exchange are installing semiautomatic equipment,
mechanical aide, and are increasing the number of communi-
cation channels to achieve a further increase in the sta-
tion's profit. There are 2 photos.

A13STRACT: The paper is devoted to the foundations of the pheno-
menological thermodynamics. The author states that the de-
duction of the second principle of thermodynamics from the
postulates of Clausins, Thomson, Carathdodory etc. implies
necessarily that the entropy increases in all the irre-
versible adiabatic processes : d S >0 . This, however, con-
is,
tradicts the fact that in certa n irreversible adiabatic pro-
cesses of the microcosm the entropy decreases. The author
uses this contradiction in order to show : 1s) The existence
of the entropy can be established, if it is assumed that the
expression for the quantity of heat supplied to the system
possesses an integrating factor depending on the empirical
temperature. 2.) The assumption leads to conclusions which

TEXTt The author states that the postulate of Thomson is the most general
one of the three postulates of Clausius, Caratheodory and Thomson and that
from it there follows the total second principle of thermodynamics. Further-
more he states that the proof of the phase rule of Gibbs given in (Ref. 3)
is worthless, since the assumptions made are consequences of the phase rule
to be proved. Some related questions are treated, Konovalov is mentioned
in the paper.
