veracity of the above formulas was checked by experiments staged in the summer of
1964 in a flat steppe terrain. Light flicker was measured along with mean tempera-
tures and wind velocities; also, Richardson numbers were calculated from gradient
measurements. A "satisfactnry" agreement between theoretical and experimental
results is reported. 'In conclusion, the authors wish to thank V. 1. Tatarskiy and

TITLE; A Device for BleG-t-r-0-1--Y-'ti-ic--SEi'arpeiling of Point Probes with
Control of the Quality of the Point
PERIODICAL: Pribory i tekhnika eksperimenta, 1959, Nr 4, pp 156-157
(USSR)
ABSTRACT; The authors describe a variant of.the electrolytic method
of sharpening point probes. A device is used which sharpens
a probe by periodic immersion of the latter into an electro-
lyte and removal of the probe from the electrolyte at a con-
trolled rate. This rate depends on the diameter of the orig-
inal rod or wire and the rate of dissolution of the probe mat-
erial by the electrolyte. The device makes it possible to
produce rapidly point probes with the quality of the point
controlled continuously by means of a binocular magnifier
or a binocular microscope MBS. Alternatively, the point
may be projected on a screen and its quality judged from its
magnified image. The device is shown schematically in Fig 1,
and its photograph is given in Fig 2 (numbering of details In
both figures is ihe same). Five support rods are fixed to an
ebonite base I Four of the support rods ( 2 and 3 )
are used to mount the main part of the device and one such
rod 4 carries a small lamp 13 A d.c. motor 6 with

The crankshaft and a small roller 11 convert the rotation
of the motor shaft into a vertical up-and-down motion of a
rod 9 which carries a clamp 23 to hold the probe. The
electrolyte is placea in a beaker 22 on a moveable table
21 . The motor is supplied through a potentiometer (or a
rheostat), which is used to alter the rate of rotation of
the motor shaft and thus the rate of the up-and-down motion
of the probe. D.c. current is supplied through terminals
(15 in Fig 2) to the electrolyte and the probe; this current
is also controlled by means of a potentiometer. A binocular
magnifier 17 or a microscope has its own stand separate
from the device itself. When wires of 0.5 mm diameter and
thinner have to be sharpened into probes, the rate of up-
and-down motion produced by the motor may be too small; for
this purpose the device can be used without the reductor 7
and the motor 6 - the crankshaft is then rotated manually
by means of a knob 20 . The following parameters can be
varied in this device: (a) the electrolyte composition and
density, (b) the current density through the electrolyte

tion of action of the electrolyte on various parts of the

symmetrical cone-shaped probes of any metal and to improve
the quality of probes already sharpened or to reduce the
probe dimensions. There are 2 figures and 3 references, 2

TITLE: Piezoelectric resistance in tellurium
PERIODICAL: Fizika tverdogo tela, v. 3, no. 10, 1961, 3247 - 3249
TEXT: A study was made of the change in resistance when monoCrystalline
tellurium specimens of different concentrations were subjected to uniaxial
elongation between 77 and 450 0K. The specimens had been previously
annealed in order to obtain an ordered structure. In this way, the
temperature dependence of the piezoelectric resistance was unified to some
extent. Present data refer to the constant n 33 =AQ/QZ of piezoelectric
resistance (current and stiess Z are directed along the trigonal crystal
axis). N f(-!) is almost linear in the region of impurity conductivity,
33 T
and displaysthe characte--i, ic deep minimum when passing to the region of
intrinsic conduction. This temperature dependence was measured for an
impurity concentration N A - 2.1015 cm-3. The constant of the piezoelectric

resistance depends greatly on the impurity concentration. The highest
piezoelectric resistance is observed in the region of intrinsic conduction,
and may be qualitatively described by a change of lattice parameters and
by the narrowing of the forbidden band. As a consequence, the number of
carriers excited by thermal motion also changes. Under these premises,
the following holds:

conditions, the pressure dependence of the forbidden band width is given by
(3-5 � 0.1)-10- 11 ev-cm 2/dyne for specimens of different concentrations.
The change of resistance in the case of uniform pressure has the same sign ik
as in the case of elongation. This is explained by the existence of
crossed atomic chains in the tellurium crystal structure. In the i urity

region intellurium, where already at 77 0K impurities are ionizeZ the

carrier'ooncentration cannot be affected by a change of the band width.
In addition, an elongation by which no new impurity centers are produced
can change only the hole-mobility tensor. The experimentally observed
dependence of n 33 on NA has not been sufficiently clarified so far. To
acquire a complete knowledge of the nature of the piezoelectric resistance
in the impurity region, it is necessary to study the effect of elongation
on the Hall effect and on other parameters of Te in this region. The high
piezoelectric resistance between - 20 and + 200 0C is a point in favor of the
usability of tellurium crystals for constructing strain gages. A. R. Regell

TOPIC TAGS. tellurium, piezoelectric modulus, temperature dependence, electric

APSTRACT: A theoretical and experimental analysis was made of the temperature de-
p9ndence of the piezoelectric effect in tellurlum in order to clarify the structure
of the valence zone. The piezoelectricresistivity tensor (quarter rank) was given
with' eight inderendent parameters: 'ff I I i w1Z i "13,- R14 1w3l -, "33, W41 and 1r44. A
schematic diagram of the respective orientations (voltage-strain) necessary to de-
termine these eight parameters is presented and methods for measuring these were
described. A variable loading arrangement was used in measuring the voltage drop.
The samples were'cut!, etched about 100P and annealed at 3200C for 30 hours. The

changes in the parameters were given as a functionof temperature ranging from -100
to 2000C. The results varied considerably depending on the parameter and on the im-
purities which ranged from 5e1014 to -8.1016 cm-3. In the temperature range of 77
to 200.0K, a.weak dependence was observed for some parameters in the region of impuri-
ty conductivity. Several relations are given for pn conductivity in terms of the
,effective density,of-states in the conductivity region and in the valence band and
Iof.the resp ective.energies for these regions. These formul as satisfactorily explain
the ' urity and temperature dependence of the effect. The larger values obtained
IMP
-for W33 and ull are explained in-terms of the dependence of carrier mobility on
effective mass for the particular lattice directions involved. Transducer applica-
of tellurium for conditions of deformation or vibration are recommended es-
pecially in the low temperature region since some coefficients exhibited such a weak
dependence on temperature. Orig. art. has: 6 figures, 7 formulas.

rior and exterior threads is being done at present on tape,
gauges and multi-thread rollers by means of multiple-thread
grinding wheels. In accordance with the new technology,
thread-cutting instruments up to a pitch of 2 mm are cut
with a multiple-thread grinding wheel. Grinding is done in
two operations requiring 2 wheels. For the preliminary out/
a grinding wheel of a slightly softer metal is used as com-
pared with that of the final grinding. Thread-cutting on
taps M6xi, M8xl.25 and MlOXl-5 is done in two passes and on
taps M12xl.25, M12xl.75, M142, M16xl.5 and M16x2 in three
passes (2 preliminary and 1 final). Grinding wheels are
provided with multiple thread by means of rollers with
annular thread. The rollers are made from carbon steel
Card 1/2 UBA, U10A and U12A. The rollers are subjected to a thermal

Grinding of a Cutting Instrument by Means of a Maltiple Thread Grinding Wheel
treatment to a hardness degree of Rs= 58 - b2. The rollers
themselves in the course of production get a preliminary thread
cut with a multiple thread grinding wheel and are finished with
a single thread grinding wheel. For cutting annular thread,
a special device on the adjusting plate of the screw cutting
lathe is used. It seryes to fix the required thxead pitch
(see figure 2). The rolling-on of thread on a multiple thread
grinding wheel requires 15-20 minutes; the speed of rotation
of the grinding wheel is thereby cut down to 1.8 m/sec. Effi-
ciency in tap ihread-cutting by means of multiple-thread grinding
wheels hawincreased "more than twice". Figure 3 shows stets of
thread-cutting instruments ground by this new method. There
are 3 figures and 2 tuables.

FTKh i GN, 1963, v- 3, 3D4-1o6 In view of the fact that the earlier high-
frequency investigations were devoted either to the design of sound generators or
to the use of high frequencies for investigation of solids, the authors have in-
vestigated the properties of liquids at frequencies above 300 Mcs. The experiment
Iwas ba-sed on the method of nonresonant excitation and reception of sound by piezo-
,electric quartz slabs and rods placed in coaxial resonators (Fig. 1). Some pre- I

The strengthening effect of carbon black is determined by the ad-
sorption properties of its particles. The surface may be modified
by radio-chemical a0dition of various compounds. The irradiation was
carried out by a CoOO source of 22,000 g-equ. Phenyl- P-naphthyl-
amine, mercaptobenzothiazol, sulfur and rubber of the type 8KS-30A
were physically adsorbed. The mechanical properties of the vuleaniza-
tes were studied on the Polani dynamometer. A considerab' -3 effect is
obtained by irradiating carbon black with rubber chemically adsorbed
on its surface.
There are 2 tables.

ABSTRACT: The suppression of the catalytic effect of polyvalent metal
ions contained in rubbers is an important, though hitherto
little investigated problem. This Cap is partly filled by
the present paper. The behavior of metal salts was investi,,,ated
in divinyl-styrene rubber as viell as in natural rubber. The
authors determine the rate at which oxy-,ren is absorbed by
rubber at various temperatures and the variation of rubber
structure from the viscosity of its solution in benzene. The
results obtained by these investi.ations aro sho,,,rn by 3 dia-
grams. It was found useful to investiEate the binding of metal
ions to stable, catalytically inactive complexes. These

not joined in pairs) show a complete blocking of the central
ion by the molecules of the addend, so that transition of
the electrons from this ion to the substratum (peroxide of
rubber) or vice versa becomes impossible. The firct part of
the present paper deals with the ability of metal salts to
form complex compounds with the various ingredients of rubber
mixtures, viz. in low-molecular compounds and in the rubber
substance. The binding of the copper ion by the antioxidant
in the benzene solution was investigated by observing the
fluorescence of the solution of these substances in benzene
and alcohol. The conditions warranting the complete extinc-
tion of fluorqscence are given by a table. As the extinction
of fluorescence may be brought into connection with the
blocking of the ion, it indicates a decrease of the possibi-
lity of a valence transition and consequently a decrease of
the catalytic activity of the metal ion. The authors then
investiC;ated the possibility of the formation of tile afore-
Card 2/4 mentioned complex compoundain the rubber substances. The

compoinids of iron and rubber with certain components of
rubber form stable complex compounds, which may be obtained
by the precipitation of acid or basic aqueous solutions
from them. The componehts which had not participated in the
reaction must then be carefully washed out. The composition
of these compounds is shown by a table. The relations of the
molecules of organic compounds to the metal atoms, as shown
in these tables, can in most cases not be represented in
form of a definite structure, and therefore this problem is
in need of further investigation. The reaction between the
complex-former and the metal in the rubber medium develops
completely but slowly. 3 diagrams contain data concerning
the kinetic oxidation of rubber in the presence of complex
compounds (formed immediately in the carboniferous medium
of the rubber), and also concerning the synthetized complex
compounds introduced into a rubber. The bound metal ions
exercise no influence whatever upon the rate of oxida'.ion
or upon the structural. variation of rubber, i.e. they lose
Card 3/4 their catalytic activity. Therefore, rubbers able to form

TW- The author!m have developed a new method for the quantitative deter-
mination. of certain;~oxygen funotional groups present in carbon black, and have
tested the validity of methods previously'iised. A rapid and accurate method for
the determination of active hydrogen in carbon blacks, using an ether solution of
the Grignard reagent, was also developed, in addition to a method for the alkali-
metric titration of the acidic groups of the carbon blacks withcatstic soda and
sodium carbonate. By assuming that the caustic soda reacts with all the acidic
groups and the sodium carbonate only with the carboxylic ones, the phenol and
carboxylic groups in the carbon blacks were determined. The general nitrogen in
the carbon black was determined by the Kjeldahl method. The latter is a variation
of the method introduced by A. P. Terentlyev and B. M. Luskiniy. Combustion can
be carried outin 4 hours, and chromic acid is used as the oxidation catalyst. Coll-
clusions are drawn on the nature of the oxygen bound with certain carbon blacks

from the developed methods and by comparing the obtained results with data of
other non-Soviet authors, &r*ata of carbon black investigation using the para-
magnetic electron resonance method. However, a large portion of tbeczygen in the
channel black has not been identified. The most complete identification of oxygen
was made for that bound with experimental carbon black of the WD(MIR) type.
Data of the channel black analysis, both of the initial and of that containing
chemically adsorbed neozone A (D), cb 2 HA (F2NA) and also captax MET (MI3T) led
to the assumption that these substances react with oxygen-containing radicals of
carbon black at the position of the weakest-bound hydrogen atom (RN-R and RS-11).
It is pointed out that carbon black chemically interacts with various ingredients
of rubber and probably with raw rubber or polymer radicals. Thus, the following
are thought to be chemically actives 1) various oxygen-containing groups, 2) sul-
fur-containing compounds - in the case of carbon blacks, produced on the basis of
petroleum and coal, 3) free radicals on,the surface - non-coupled electrons of
atoms of carbon and oxygen and possibly atoms of sulfur and nitrogen, bound Iry
chemical bonds with carbon atoms of the carbon black crystalline lattice. The
sulfur-containing groups are thought to have the structure > C = S and --YC - SH.

TITLE: Protection of natural and synthetic rubber from catalytic oxidation
under the action of copper and iron ions
PERIODICAL: Kauchuk I rezina, no. 4, 1962, 10 14
.TEXT: A study was made of the causes for the different effects of ingre-
dients on the catalytic oxidation of NR (smoked sheets) andCKC-30A (SKS-30A) in
the presence of iron and copper. It is assumed that metals with changing valenc:L-s
can speed up both the reaction of initiation as well as that of chain development.
The reaction which determines the rate of initiation is the decomposition of hydro-
peroxide under the effect of metals. The authors discuss the activation of oxygen
and the formation of active intermediate compounds of metal ions with oxygen. The,,
possibility of repressing the accelerated oxidation of NR and SKS-,30A in xylene
solutions and the solid state was investigated by binding the metal,lons Into cat.,
alytically inactive complexeS. Certain rubber ingredlento Garved au the addends
in the complexes. Obtained data led to the following conclusions: 1 ') the higher
the concentration of the metal ions in the rubber solution, the faster its viscos-,

ity drops; 2) the catalytic activity of the copper ions with respect to the rub-
ber oxidation is much higher than the catalytic activity of the iron ions; 3)
certain ingredients introduced into the rubber mix have the ability, partly or
completely, to suppress the catalytic activity of the copper and iron ions. A
further study was made of the catalytic oxidation In the rubber solutions in the
presence of~anti_aging agents containing amino- and hydroxyl groups, of acceler-
ators containing sulfur and an amino- group in the molecule, and of a vulcanizing
agent. The following conclusions were drawn: the accelerators of vulcanization
(tetrame thylthiuramdi sulfide, sodium die thyldithiocarbamate) and anti-aging, age
(n-oxyphenyl-fl-naphthylamine, dinaphthyl-n-phenylendiamine, dioxydiphenylamine),
form firm compounds with the metal ions of varying-valency metals, not having any
~catalytic activity with respect to natural and synthetic rubbers, but character-
istic of the metal ions themselves. These compounds most probably have the
~`s'tructure of intercomplex slats. Certain complex compounds, formed by the metal
Aon of varying valency, and deactivating substances, are strong inhibitors of
rubber oxidation. A new method for synthesizing effective inhibitors is recom-
mended. There are 5 figures and 1 table. The reference to the rMst recent English-
