TITLE: G-Omparative Evaluation of Kerosene and Oil Reagents Used in

ABSTRACT: The object of the work was to provide a comparative evdluatior.
of the reagents most widely used in the USSR: kerosene (K),
transformer oil (TO), and SV machine oil (MO). The effects of
these reagents on the variation in the wettability of mineral
surfaces and foaming was studied separately. The following are
the findings: Commercial K contains a substantial amount of
volatile fractions (under 150-1800) not capable of flotation. More
effective reagents are provided by high-boiling fractions of K
"(;80-Z20" and over 2200), which increase the hydrophobic nature
of MoS2 and improve foaming. The absence or diminution of
polar compounds in K impairs its flotation qualities. TO and MO
Card I/Z are similar to the high-temperature fractions of K in their

flotation properties. However, TO impairs roaming, while MO and K improve
it. The distillation fractions of TO and MO provide no differences in the
properties observed. Addition of a small ari.nunt of pine oil makes it possible
to control the size of the bubbles. In the experiments conducted on the flotation
of MoS2 in a mixture with SiOZ, the highest level of extraction of MUS2 was
obtained when MO or K fractions were charged along with pine oil (10 g/t).

Beneficiation of the Marganese Ore of the Labinsk Deposit

I'he results of a study of the capabilities of heneficiation of
the Mti ores of the Labins~- deposit, the major ore minerals of
which are rhodochrosite and Ca rhodochrosite, are set forth
The chemical composition of various samples is presented. The
properties of the ore minerals and their fine dissemination, with
intimate intergrowth with calcite, provides the basis for classi-
fying this ore as non -gravitational. Experiments in jigging and
concentration on the table have confirmed this. Flotation can
be attained only at a high cost in oleic acid and water glass and
with two steaming operations performed at high temperature.
Satisfactory results were obtained when liquid soap was substi-
tuted for oleic acid at steaming temperatures of up to 400 C. By

flotation with prior washing of the dissolved salts it is possible to obtain con-
centrates containing 29-30 percent Mn and 89 percent recovery thereof The
Mn contents may be increased to 40 percent by roasting at 400-5000.

ABSTRACT: Selection of bulk concentrate by the following flowsheet: 2 thickenings
and washings, fine grinding, primary copper-pyrite flotation and one
secondary, yields copper-pyrile concentrates containing 0. 166% Co
and 0-93% losses. Cu extraction is 80%. The reactants are 10 g
xanthate arid 40 g DS frothers per ton. Separation of cobaltite from
pyrite involves high Co losses.

ABSTRACT: A verification, on the basis of experimental results obtained
by other authors, is presented of conclusions previously sug-
gested (RZh Met, 1957, Nr 6, abstract 9492; Nr 11, abstracts
20782 & 20784) to the effect that the kinetic regularities of
flotation indicate that it proceeds by two stages. The verifica-
tion confirmed that two distinct periods dre observed in the
process of flotation. During the first period, variation in the
mean rate of flotation proceeds primarily in accordance with
the equation of K. F. Beloglazov, and in the 2nd by the equa -
tion of S. 1. Mitrofanov. The author advances his own kinetic
equations for the entire flotation process, comprising both
periods. Bibliography: 12 references.

ABSTRACTs In lakes and rivers in Alaska and Kamchatka, where the males of
two species of Oncorhynchue (Krasnaya - Onc. nerka and
Gorbusha - Ono. gorbuscha) die after fulfilling their task as
fecundatorep the inflow of phosphates amounts to 1/4 of the
total inflow of phosphates (Refs 1-4). In the last decade, the
number of Kraenays. males foll from 55p2OO (1937-1947) to 9,200
(1946-1958). To answer the question as to whether this
circumstance had an effect on the living conditions of the
biogenio elementst the author compares the phosphate quantity in
the water of Lake Daltneye during the two above-mentioned
,rhe point'of time towards the eni of
periods (Table 1, Fig 1).

phosphate quantity is maintained, but a falling tendency can
already be noticed. Figure 2 shows the vertical phosphate
distribution in the water of Lake Dallneye on August 28, 1946
and August 26, 1958, revealing a perfect parallelism between the
number of fish immigrating into the lake for spawning and the
phosphate amount in its water. The reduced immigration of

ABSTRACT: A method was proposed for determining the discreteness of computers
of a ship's course. The method is based on analysis of spectral density of yawing
processes and the oscillation rate by dead reckoning in order to determine the
maximum frequency range In which the total dispersion of rejected harmonies to
sufficiently smal; or at least does not exceed the given accuracy, and from which
the original Information on the courBe and velocity was obtained. The theory of
random stationary functions and parts of the Information theory (Koteltnikov's
theorem) were used in the method. A detailed account of the method was given,

TITLE: Etching of Dielectrics by Ionic Bombardment. (Travleniye dielektri-

PERIODICAL: Doklady Akademii Nauk SSSR, 1957, Vol 1%, Nr 5, PP 1001-1003
(U.S#S.R.)
ABSTRACT: The following is shown by the present paper: On the occasion of the
bombardment of the surface of a dielectric by means of gasions
geometrically regular etching figures may form whioh reflect the
crystal structure of the object.Boubardment with positive ions was
carried out in a low pressure discharge. The action of neon ions
upon arystalline and amorphous dielectrics was investigated.
Reference is made to some previous works dealing with this subject.
When the cathode vas constructed, the fact was taken into account
that cathode spattering is proportional to the density of the ion
flux, and that there is lead deponiting of metal at those points
wher-3 current density is greater. If, therefore, a greater current
density in produced on the surface of the dielectric than at
neighboring points of the metal, the dielectric is not powdered
with metal. This happens in the oase of a periodio development of
the potential being caused, so that indentations correspond to the
domains of the dielectric to be spattered. The or7stalline di-
eleotrics used were quartz, Iceland spar, rock salt, and seigaette

salt. Besides, also the amorphous dialeotrica amber and plexiglass
%yo.re etched. Etching with ions took place on the occasion of differ-
ent kinds of discharge. For airber and plexiglass the method of ion
etching must be selected with particular care; I = 2 - 2,5 me/cm,
V = 1 5 kV and t = 2 - 3 hours. The surfaces of the amber and the
plexigla.ss were uniformly destroyed ind the figures of destruction
had no geometrical pattern. On the occasion of the etching of quartz
vrith ions in the Z-aection, distinctly marked triangles were ob-
tained. Of all dielectrics, quartz ia the most difficult to investi-
gate. With a weak ion bombardment no figures at all are formed, and
in the ca-se of a heavy bombardment the same figures are obtained as
in glass. When rook aalt is etched (surface ~100) ) cubes are
formed. The etching figures thus obtained can -be used for deter-
mining the symmetry of the crystal. This method is simpler and
often more reliable than that employed in conneotion with other pro-
cesses. (With 3 Illustmtions)-

In order to inhibit the influence of temperature
and the variation of ion-current density on the dielectric,
tubes with intense water cooling were used. In order to elimi-
nate the disadvantage of the metallic nets, a new method was
developed, by means of which the dielectric is heated to such
temperatures at which it is in a semiconductor state. By means
of the instrument UIT-1 rook salt was treated for 3 hours at a
temperature of 4000C, an accelerating voltage of 3 kv, a
current of 3 ma, after which it was investigated by means of
an electronic microscope. Figure 3 shows the result obtained.
By means of this method, the influence exerciatd by the 4vapora-
tion of the dielectric and the critical temperature for the
intense evaporation of the dielectric were investigated. The
result obtained shows that the structure formed by evaporation
of the dielectric is identical with those obtained by applying
the two other methods. There are 6 figures and 5 Soviet refer-

caused by the Aructure of the ion beam. First the authors describe the

TITLE- Selective etchings of aluminium crystals
PERIODICAL: Kristallografiya, v. 7, no. 1, 1962, 152 - 153
TEXT: The concentration of chemically-produced etch
patterns depends on the method of growing the crystal, its
purity and the orientation of the etched surface of the crystal.
According to Braun et al (Ref. 8: Philos. Mag., 3, 35 ' 1312-1317,
1958), the maximum is achieved for surfaces of the type ~1113
Defects in the structure of the crystal, which arise during
deformation, are not detected by this method of etching: the
distribution of etch pits and their concentration is about equal
on a polished surface of a crystal in the deformed and in the
non-deformed states. On the basis of results of layer-by-layer
etching and data published in the literature, it is concluded
that without special ageing treatment of the investigated
crystal the etching agent of Lacombe, Beaujard and Wyon will
reveal distortions in the crystal structure which occurred during
growth; accumulations of dislocations corresponding to

Selective etchings of E073/E335
boundaries of disorientated sections of the crystal can be
reliably detected. Ageing undoubtedly changes the substructure
of the investigated crystal and this in highly undesirable when
studying the influence of deformation or irradiation on the
structure of the crystal. Therefore, the authors have attempted
to find methods of etching which will reveal "fresh" defects,
Observations have shown that electrolytic and ion-bombardment
etching reveal "fresh" dislocations arising in the crystal
during the process of deformation by shear. This is illustrated
in microphotographs of aluminium single crystals which show that
the slip traces appear in specimens etched by means of an
electrolyte as well as in repolished specimens that have been
subsequently etched by ion bombardment. Details are given on
the conditions of electrolytic and ion-bombardment etching in
the applied experiments. There is I figure.

TITLE: Ionic Deposition From Carboxylic Divinylstyrone Latexes
(Ionnoye otlozheniye iz karboksilsoderzhashchikh divinil-
stirollnykh lateksov)
PERIODICALi Kolloidnyy zhurnal, 1,058, vol XX, Nr 3, pp 293-297 (USSR)
ABSTRACT: The manufacture of rubber products immediately from latex
by means of ion deposition Is based on the interaction of the
cations of the electrolyte diffused in the latex and the pro-
tective shell of the globules. "he result of this inter-
action is the astabilization o f the globules und the forma-
tion of a gel. Synthetic rubbers containing carboxyl groups
in the molecule form very resistant vulcanizates. In the
article, tvo carboxyl-containing divinylstyrene latexes are
investigated with regard to ion depositio r, - It is shown
that at an increase of the p1l of the latexe:3 from 4 - 10.1
the surface tension decreases from 54.2 - 40.1 dyn/cm. The
change in viscosity is negligible in latexes containing
4 - 1C~!, metacrylic acid. Graph 1 shows that an increase

position. The increase of the pH also decreases the relative
elongation and the ultimate swelling oil the latex, but the
tensile strength and the equilibrium modus increase. In the
process of ion deposition and the subsequent treatment of
the films obtained, calcium chloride interacts not cnly with
the protective substances of the latex globules but also with
the carboxyl groups of the polymer molecules, which is the
cause of the structurization. The calcium atoms may combine
with two carboxyls in two different polymer molecules con-
necting them by stable chomical cross bonds.
There are 5 graphs, 2 tables, and 4 references, 2 of which

TITLEs The Interaction Between Natural Rubber and Maleic Anhydride
PERIODICALt Kauchuk I Rezinal 1960, No 5, PP. 3 - 6.
TEXTs The reaction mechanism between natural rubber and maleic
anhydride during the rolling process was investigated. The experimental
procedure is outlined and the concentration of the maleic anhydride, the
distance between the rollers, the temperature of the rollers and that of
the oxygen In the medium were studied as to their effect on the addition
reaction of the maleic acid and the rubber, as well as the structuralizing
process. The results of the experiment are discussed. Both the rate of the
gel formation and its maximum amount increase with an increase in the maleic
anhydride concentration when the natural rubber Is masticated in open air
(Fig. 1) The amount of the gel increases until the maleic anhydride Is
all spent (Fig. 2). It was shown that the addition reaction of the malsic
anhydride, when the content of the latter is no more than 5% in the mixture,
follows the first order reaction equation. It was alDo found that in the

rolling process of the natural rubber with maleic anhydride, the reactions
of addition of the maleic anhydride to the rubber and the structuralizing
process are parallel. In rolling with a clearance between the rollers, them
structuralizing takes place with an inductive period, which decreases with
an increase in the concentration of the maleic anhydride. The rate of the
structuralizing during rolling in an argon atmosphere is considerably high-
er than in air. An increase in the temperature from 20 to 400C when masti-
cating the rubber in air causes destruction of the formed gel and has no
practical effect on the quantity of the added maleic anhydride. There is
a linear relationship between the quantity of added maleic anhydride and
the amount of formed gel. There are 5 figures and 11 referencess I Soviet,
4 English, 1 German and 5 French.

virial coefficient diminished on addition of the optically invisible
polyisobutylene. Quantitative measurements of the degree of
~
lassociation are possible only on double extrapolation of the light
!scattering to zero angle and zero concentration. On changing in
4concentration a mixture of two polymers may pass from a true solu-
Ition to a rapidly separating emulsion via a stable intermediate
colloid state. For a 1:1 mixture of polystyrene and polyi3obutylene
the true solution exists up to a concentration of 0.7 em. of the
Imixed polymers per 100 ml. toluene, and the emulsion separates when
!the concentration exceeds about 1.2 M.1100 ml. "The authors
