ABSTRACT; The authors describe the results of their experimental
investigation of the limit of the elastic state for a plane
state of tension which was generated by a stretching and
torsion of thin-walled nickel tubes. A high exactness was
aspired. The exterior diameter of the tubes was 5 mm for a
thickness of the wall of 0,2 mm. The experiments were carried
out under a direct load by weights, the measurements were
made b~ mirror instruments. The determination of all points
of the sought limit at a piece of the tube was inexact because
of the remaini-ng action of preceding experiments. It is stated
that reliable measurements are possible only ca. 10-15 minutes
after the plastic deformat-ion, because before this time the
creeping is too large. On none of the obtained limits the
authors found angles, the existence of which is asserted by

TEXT: The term 'quality of filling' is defined as the amount of re-
sidual air bubbles left in the housing of a floating gyroscopic in-
strument after filling with a special fluid to reduce the total
amount of friction in its bearings. The authors consider the effects
of air bubbles on the gyro errors and describe a special installa-
tion and method of filling. The apparatus has a bellows type ther-
mostat with two visual indicators of the bellows pressure. The in-
dicators are arranged so that the difference in their readings, i.e,
the reading of vacuum duringthe filling process and of atmospheric
pressure restored after it had been finished, determines accurately

ABSTRACT: Angular velocity transducers consist of a gyroscope with Jwo degrees of
freedom which is provided with a device which, when the gyroscope frame deviates fro,M
its initial position, applies to it a moment, proportional to the angle of deviation of the
frame, which tends to return the frtune to Its initial 'position. A schematic diagram of ~:x
such a transducer is shown in Fig. 1 of the E nclosur6. This moment can,be produced
either by mechanical springs or by a special system which is called an~ "electrical springf.x
The present paper describes a transducer with a potentiometric putputin which the

meter.. 2. When the supply voltage to the gyrometer varieswIthin the limits. + 5%, the.~
magnitude of the output signal Is practically directly proportional to the voltage and
varies within the limits + 0. 84% about its meam value, correspondingto, the nominal
value of the supply voltage. 3. When the supply voltage frequency oscillatek within the
limits + 2%, the magnitude of the output signal Is practically directly proportional to the
frequency and changes within the limits + 1. 4% of the value for the nominal supply
frequency. 4. The ranges of tolerance !or voltage and frequeacy can be computed, using
two formulas derived in the paper, on the basis of a given range of.. toleiance for the
speed of the gyromotor. 5. In order to obtain a high accuracy in such a transducer it
is necessary to impose stringent requirements onthe supply sources (particularly the- ;-,V,
supply frequency stability), 6. In 6rder to estimate the quality of production of such

It is pointed out that the most vulnerable element In a potentiometer Is the electrical con-4

most serious reliability problem in automatic pilot instrumentation. The design of-are-,

pressure with time is investigated. In this connection, it is noted that for small objects
like wipers the effect of internal stresses due to thermal and mechanical processing
can be relatively large. The effect of the natural frequency of oscillation of a wiper or
the wiper assembly on the reliability of contact is examined, and it is concluded that the
frequency of natural oscillation of a wiper must be about twice as high as the maximum
frequency of the vibrations actually occurring. On the basis of the above codsiderations
a method for designing the main parameters of wipers is developed which takes into
account given operating conditions such as vibration and overload; in this design method
a wiper is considered as a beam, one end of which is fixed and the other end of which, the
point of contact, is considered to be supported. on rollers. Design formdlas are derived
for arm-type wipers of constant circular cross-section having a flattened segment near
the mounting place. The design formulas derived are conveniently summarl7ed in a
Table, and their use Is illustrated in specific examples. The method shows that for
given operating conditions and material the magnitude of the desired contact pressure
uniquely determines the optimum value of the wiper diameter and length. The operating
conditions as well as the wiper metal uniquely determine the optimum magnitude of the

carrying wipers like commutator brushes, elastic parts of central contacts, 9tc. Orig.

TEXT: A so-called synchrophone is described in which the fluctuation
noise at the output of the measuring microphone is*suppressed by the parallel
connection of two similar amplifiers to a sensitive element consisting of two
piezoelectric crystals. The two crystals are separated by a grounded plate, and
the amplified crystal signals are fed to a synchronous detector. The presence
of two synchronous electrical oscillations permits the use of a simple correla-
tion method for suppressing the fluctuation noise. By this method a reference
voltage being synchronous with the signal (synchrophone principle) is obtained,
so that highly stable piezoelectric elements can be used as pickups at low sound

pressures. An important requirement of the system is the linearity of transfor-
mation, but not so important is the degree of similarity of the piezoelectric
elements and the amplifiers. A calculation shows that the fluctuation noise lev-
el at the pickup output can be lowered to 30 - 35 db. There is I figure.

Abstract It is shown that the variety of bentonite - Al-Bentonite (I)
is gradually saturated not with H+ ions, but with A134* ions
during the process of refining by electrodialysis and, consequen-
tly, instead of its H-variety, the Al-variety is formed con-
trarily to the usual idea. The formation of Al-bentoaite is
the result of partial destruction during the electradialysis
process in colloidal minerals, at which the amount of exchange-
able A13+ rises sharply with the decrease of pH of the sus-
pension to a certain limit. It is shown that at the poten-
tiometric titration I the amount of alkali absorbed by I is
proportional to the amount of exchangeable A13+, if the
chemical interaction of the alkali with the alumosilicate

nucleus of I was insignificant. The influence of the con-
tent of exchangeable A13+ on some colloidal-chemical pro-
perties of electrodialysed suspensions of I (structural viscos-
ity, dynamic shearing stress, stability and water yield) was
also studied quantitatively. The hydrophilic nature and the
electro-kinetic potential of colloidal I particles decrease
with the increase of the exchangeable A13+.

PERIODICAL: Doklady All SSSR, 1958, Vol- 118, Nr 3, PP. 540,542 (USSR)
ABSTRACT: Ascangel is one of the most characteristic representatives of
true bentonites in the USSR (Askani Mine, M&kbarafte
Di6trict, Georgiqn M)~ ~ lt8 highly disperse
fraction is a typical alkaline MOLItmorillonite. Because of
its properties this mineral plays an important r8le in the
technique of trial borings. The isolation of colloidal
fractions of ascangel is of great importance also for the
following industries: foundry-, soap-, rubber-, paper-,
cramic-, varnish- and color-, building material-, weaving-,
perfume-, pharmaceutical, and many other industries (ref.
6,P). The coarsly disperse fractions of ascangel (contents
approximatelY 30%) exert a negative influence on the colloidal
properties of suspension. It sediments in the case of small
concentrations (3,5 - 4 %). With increasing concentration
(5 - 8 %) the mechanical resistance of the system increases
only slowly and the tixotropic properties decrease. The
Card 1/3 influence of stabilizing and peptizing reagents on coarsly

Concentrated Ascangel
20-3-35/59
and highly disperse fractions shows very different results.
Therefore the properties of the suspensions with coarsly
disperse fractions can be regulated only with difficulties.
Thus, the problem of a suited raw material for colloidal bore
sus-Densions is solved by the isolation of highly disperse
fractions of ascangel. The present methods are in-sufficient
Since the chlorine salts of 2- and 3-valent cations are the
most aggressive electrolytes (ref. 9) there is possibility of
separating suspension phases of ascangel with small
concentration of the electrolyte by means of the usual
industrial centrifuges (UP to 3000 rev/min.) in a productive
way. BaC12-solution was used as precipitator. After the
separation of the dispersion medium a paste of the highly
disperse fractions was formed. The paste was peptized with
NA2SO4 in order to restors its colloidal properties. The
obtained product, analogous to the American Akvazhel was
called "enriched ascangel"..Separation of the coarsly
disperse fractions (31 %) from a diluted ascangel-suspension
was achieved by a vertical centrifuge. In order to avoid
the formation of barium carbonate the suspension was first
Card 2/3 acidified with HC1 to PH 6. The peptized paste had a PH - 6,8.

Concentrated Ascangel
20-3-35/59
Water suspensions of enriched ascangel show highly
tixotropic properties which they.retain within a wider range
of concentration than the formerly used ascangel
preparation "Askankoll" (fig. 2). The suspensions of the new
preparations are durable and can be used in the above
industries as active interstitial, binding, adhering, and
suspending material, plastificator, fat substitute, etc.
There are 2 figures, I table, and 11 references, all of which
are Slavic.

a weak concentration of an electrolyte and to restore
the colloidal properties of the substance by reverse
peptization. For their ex-periments the authors used
highly efficient industriai centrifuges (2,000-3,000

tation of coarse particles (>l# ) was also carried
out. As electrolyte the authors used BaCl 2* Due to

such a suspension is possible in a centrifuge
(1,500 - 3,000 rmp) or by means of vacuum filtration.
Coarse ascangel particles, which constitutue about

from a dilute suspension (- 2.5%) in a vertical se-

Colloidal properties can be restored to the paste by
the use of Na2SO 4 in stoichiometric proportion to
the initially added BaC12. The obtained colloidal
product represents a highly disperse fracture of true

ABSTRACT: The arrangement of the electrolytes between the soil and
the plant determines the assimilability of the elements
serving as nutritive substances. This is one of the processes
originating in the soil, which are connected with its
absorption capacity. In many cases the equilibrium
concentrations of the necessary substances are rather slight.
This especially concerns the oxides of polyvalent elements
in carbonate, alkaline and other soils. In theea cases the
adsorptive distribution of these and other elements can be
thoroughly changed by introduction of organic substances
which form organic-mineral complexes with polyval~ant
elements. Such complexes can be formed by oxidative destruction
Card 1/4 of polymeric hydrocarbons (various waste of vegetable raw

and Their Application Possibilities
products). They are excellent substances for the formation
of new kinds of microfertilizers mentioned in the title
in easily accessible and assimilable form (Ref 1). Thus
elements necessary for the plants can be introduced as
non-ionizable complexes. They are absorbed by the soil to
an incomparable weaker extent than the ions of the same
metals. Further they are able to stand the conditions with
sufficiently high pH-values. Chemically similar compounds
were used mainly in foreign countries - so-called chelates
(Ref 2). They differ, however, considerab'y b~- their
influence on the plants. Figure 1 shows the dii.,~rams of
potentiometric titration of organic iron compounds, called
OP-V-Fe and OP-M-Fe by the authors, beside a diagram of
FeC12 and FeCl 3- solutions with a 2 n-solution of NaOH.
The first mentioned microfertilizers are not precipitated
by this titration, but change their coloring and turn into
colloidal solutions. This is their specific characteristic.
Further investigations lead to the production of preparations
Card 2/4 of higher value. In collaboration with M. V. Pirtskhalava the

New Kinds of Organic-mineral Microfertilizers SOV/20-126-2-54/64
and Their Application Possibilities
author developed 13 kinds of microfertilizers (Ref 1).
Apart from polyvalent metals they contain carbohydrates
with different molecular weight and optical activity, a
composition of salts of organic acids, decomposition
products of vegetable proteins et al. Some of them
apparently play the part of biogenic stimulants. Experiments
with these preparations indicated a large range of application
under working conditions; fighting vine chlorosis, in which
case Fe- and Mn-compounds proved the most successful. The
resistance of the plants against the factors of surroundings
such as temperature, soil acidity, soil salt content et al
is increased. Many colloidal systems (Ref 3) and apparently
also fermentative colloidal systems are stabilized thereby.
Consumption amounts to several dozen grams (seed saucing)
up to several kilograms (spraying). As an illustration
experimental results obtained in the Sovkhoz Khirsa are
indicated. T. G. Mazanashvili (Institut vinogradarstva i

ABSTRACT: The present paper, which was delivered as a report
during the IV Vsesoyuznaya konferentsiya po kolloid-
noy khimii (4th All-Union Conference on Colloidal
Chemistry) in Tbilisi (1958) offers the results of
a study of the effect of different electrolytes on
thixotropic structuration in suspensions of--ascangel
from the Ts ikhis-Ubani deposit in the Gruzinskaya SSR.
The authors investigated the structural-mechanical
properties of suspensions in dependence on adsorptive,
electrokine tic and o-t;her surface-cheminal changes

Surface-Chemical Phenomena and Structuration in Ascangel Suspensions
occurring during the interaction of ascangel with the
electrolytes. The change of the structuro-mechanical
properties of suspensions of electrodialysed or al-
kali-treated ascan-el greatly depends on the change
in character and content of easily soluble Al and Si
compounds. Curve 1 in graph 1 shows that the quantity
of exchangeable Al (basic and trivalent Al ions) formed
during electrodialysis on the surface of the particles
sharply increases with diminution of the pH value of
the suspension, After prolonged interaction with
growing quantities of NaOH the quantities of exchange-
able Al and Si compounds in ascangel suspension are
also on the increase. The content of dissolved sili-
cates in alkali-treated suspensions increases by se-
veral times at a temperature increase from 25 to
130 Cc The sharp break in the structuro-mechanical

properties of the suspension with the change of the pH
of the suspension coincides with the beginning of abun-
dant formation of exchangeable Al and Si (graph 1).
The effect of the electrolytes (Na 2SiO39 Na4P207?
(NaPO 3)6 9 NaA102, 'TaOH, Na C03, etc,) on the structura-
tion of electrodialyzed asLngel suspension was
different. On interaction of the suspension with Na 2sio 31
(NaPO3 )6 and Na4 P207 the formation of thixotropically
fully reversible sbructures could be observed. These
structures formed-as a result-of intensive adsorption
of multivalent anions, the increase of the quantity
of easily soluble Si compounds on the surface of the
particles and the high values of the f -potential.

between the suspension particles. NaOH and Na2CO3
occupy an intermediate position between these two kinds
of differently acting electrolytes. In their introduc-
tor notes the authors mention A.V. Dumanskiy Z-Ref.

formation of colloidal systems with thixotropic proper-
ties mostly depends on the lyophilic character of the
disperse phase, P.A. Rebinder and his school f Ref. 2-7
maintain that thixotropic. structuration in aqueous clay
suspensions with anisodiametric particles is favored
by the highly hydrophilic character of most of the par-
ticle surface, I,A. Uskov 4'Ref, 9 7 forwarded the opin-

ties of clay suspensions depends on the excess amount
of introduced electrolyte. According to S. Mattson
Z-Hef. 10-7 dispersity, hydrophilic character, plas-
ticity and other properties of Al-Si colloids are pre-

ABSTRACT: Conditions for production of highly concentrated and stable colloidaL
solutions of polyvalent metal hydroxides were studied and. a number of their col-
loid-chemicAl properties were investigated. Colloids were produced with di- and.
trivalertiron, manganese, aluminum, chromium, cobalt and copper. Sols were
purified by ordinary dialysis in cellophane sacks to pH 7-9 and specific conduct-
ance of 10-3-10-4 ohm-1. cm-1. Only sols of trivalent iron were obtained even
in the acid region. Sols were stabilized by the new type of stabilizers madefrom

thermal destruction. These stabilizers are complex mixtures consisting of the
Lype of polyhydrdxy carboxylic acids of low molecular weight, capable of produc-
ing water soltble and stable in alkaline medium complexes with polyvalent metals.,
These complexes are similar to metal-EDTA Complexes, but are much more
stable. These stabilizers enable production of ferric hydroxide colloids up to
the concentration of 119 g/1. Further increase of the concentration of sols Was
done by evaporation at 50- 600C. Without exception all sols of polyvalent metal
hydroxides were negatively charged, which is characterized by-the nature of the
stabilizer. All these sols are polydispersed and consist of spherical particles.
Their particle size ranges from 10 to 460 m Orig. art. has: 2 tables and 2
