;A,FsTnAcT: The device (see Enclosure 1) operates by measuring the velocity vith
';which a metallic needle penetrates the tested.specimen. 'The needle is under a con- 1-
istant pressure supplied by a pneumatic cylinder. To stabilize the pressure, com-
:pressed air passes into the cylinder through a reducer. and is- manometrically con-
Itrolled. Readings are taken from the moment the needle touches the epecimen,, and
;continue for-a definite period of time. The depth of penetration is measured on the '
iscale with an indicator fixed on.the needle. The hardness of the rubber is deter-
1.mined fromthe velocity of penetration. Orig. art. has: 1 figure.

ABSTRACT: In a letter to the editorial board of the periodical
"Izvestiya vysshikh uchebnykh zavedeniy - radiotekh-
nika" the authors state that high frequency heating
in the electric field of a capacitor is especially
suitable for the rubber industry. Thereby, they
refer to the paper of A.V. Netushil, published in
"Radiotelkhnika-l', Vol 1, Nr 1, p 25. In. this con-
nection, the authors list the technological proces-
ses ahich are developed with the application of

PERIODICAL-.Kauchuk i Rezina, 1959, Nr 4t pp 19-23 (USSR)
AB&TRACT: latex foams can be gelled and vulcanized by radio-
frequency current in the 10-20 mc/s range, by high-
frequency current from machine generators in the 500 to
10,000 c/s range, or at power frequency of 50 cls.
Experiments were made using moulds formed of reinforced
rubber vich electrode in the base and in the lid of the
mould. St, -adard "Revertex" mixes containing 5T,;@
dibutylphthalate plasticizer were used for these testso
Dif 'iculties through corrosion were encountered when
worKin6 at 50 c/S frequency with the original aluminium
electrodes. Tests were made with various electrode
materials listed in Table 1 and it was found that stain-
less steel, mark EYaIT, showed only 0.002@S weight loss
on a four-hour test at 50 c/s and negligible corrosion
with up to 10 or 12 repeat tests of this duration. At

A iviethod of Gelling and Vulcanizing Foamed Articles from Latex
is prolonGpd indefinitely. The samples first tested
were 100 x 100 x 35 mm in dimensions. The resistivity
of various Revertex mixes, and of the foaa blown from
them to 3 times oririnal liquid volume, are given in
Table 2. Figure 1 shows ch@?..nge in resistivity v.ith
temperature at applied voltages of 5 and 8 volts. Figure
2 shows the current/voltage relationship for a foam
extended by a factir of 5.5,,and variation of resistance
with expansion of the foam-is tabulated in Table 3. The
resistance o.f the later mixes and the foams folioas Ohm's
law, and the resistance increases considerably on foaming.
The curve of temperature versus time for electrified
inten@ities of 12.5, 11.0 and 6.2 V/cm are shown in the
curves of Figure 3. ExperimentE were then carried out
on zpecimens L60 x @1*50 x 40 mm at -0 V (12.5 V/cm) and

esuimated /at 0.3 to 0.45 kWh per kg of foam (or sponge latex).
In order to -oroduce articles such as car seat cushions with
cavities in the foam, it is necessary to dispose the
electrodes in the projections forming these cavities in
strips so that the area of the top and bottom electrodes
are equal. Exploratory trials were made on cuzhions -950 x
260 x 200 ,mm dimension, load@d at 6 V/cm and with an initialo
50 C/s culrent of 0.014 A/cm . Temperature increased to 130 C
after 015 minutes power application, and was allowed to decrease
to 95 C after switching off before the mould was opened (30
minutes cooling time). It is suggested that similar methods

ABSTRACT: Preheating improves the strength of bcnd between the Parts

of the tyre by increasing the interaction between ruboer
m:L-,es at the interfaces belween layers, as a result of
higher plasticity and dispersibil-it.y. it gives increased
adhesiveness at these surfaces throush diffusion of
sulphur into the rubber mass away from the surfaces and
reduction of stresses in the casin- at different sta-es
of the manufacturing p-rocesses.
With preheating before mould.4-r-g cy, before -valcarnIs at ion,
tyres show increased lives on rig test anuft considerable
decrease in scatter betweer- &-eatest and least lives on

Preheating Tyre Casings Before Moulding and Vulcanisation
assuming that the specific heats of the different rubber
mixes are similar, the carcass and breaker rubber will
attain higher temperatures. This is a desirable state of
affairs and is one of the advantages of HF heating as
compared with preheating by hot air.
Heat treatment may also be applied to moulded tyres before
vulcanisation.. In this case, temperature distributions are
as shown in Table 4 and Figure 6. (Figures 5 and 6 show
temperature distributions with EF heating and with hot-air
heating.) Where a moulded tyre is preheated before vul-
canisation, the scatter on life test is reduced if the tyre
is subsequently cooled before vulcanisation. The curing
bag attains a high temperature on account of water in the
composition of the lubricating medium used on the surface of
the bag. The authors suggest that the best effects of heat
treatment are obtained with two-stage treatment before
moulding and before vulcanisation; comparisons of rig
test lives with BF heating at different stages of manu-
facture are given in Table 6.
Heat treatment of vulcanised tyres is also beneficial,
Card3/5 having an annealing effect upon stresses remaining in the
SOV/138-58-11-"r/14
Preheating Tyre Casings Before Moulding and Vulcanisation
tyre after vulcanisation. Rig tests on tyres so treated
show double life, on average, and great reduction in
scatter.
Results of field tests on three different classes of road
surface are shown in TaUe 7, and confirm that tyres
subjected,to EF heat treatment before moulding and
vulcanisation have substantially better life than standard
tyres, particularly on bad surfaces.
HF heatIng shortens vulcanising ti-me, particularly as the
curing bag is brought up to its operating temperature durirZ
preheating. Vu@canising time can be reduced from 110
minutes at 145 0 0 (with standard vulcanisation) to 76
minutes at 160 C with HF preheating, with gneral improve-
ment in bond strength between layers as is evidenced in
Table 9. Table 10 compares rig test lives of 8yres with
standard vulcanisation for 110 minutes at 145 C wit-h
lives of tyres vulcanised for shorter times at higher
temperatures following '193 heat treatment. Vulcani-sat-i3n

@nvol@re any loss'of generality, since the analysis can be readily
extended to any operator with sign-alternating coefficients. The
method was experimentally checked on one-dimensional algebraic,

thod can be used for simulating linear and nonlinear operators,
of linear algebraic equations, in the synthesis of automatic con-

i@' TEXT: The paper proposes a device that provides a/ reading of the most sl"gnifi-
cant voltage values in electric analogs and thus afford representation, for exi.-ample,
of the maximum values and the general character of the, variation of bending oments
in an electric analog of a stressed beam. The voltages to be measured enter multi-
channel commutator, where a control block governs their successive entry intp the
imput of a cathode-ray indicator (CRT) over a time T . The scanning of theT
is synchronized with the beginning of the commutation, and its duration is sele
to equal the commutation period of the entire ensemble of the voltages to be m;4as-
ured. The 3 alternative versions of this arrangement differ in the type of the @om-
mutator used and the method of the synchronous scanning along the axis of the
abscissae: (1) An electromechanical commutator with a step-by-step switch.
Card 1/2
Device for the visual observation of the S/777161/000/000/004/005
(2) An electromechanical commutator with a collector. (3) An electronic commuta-
tor. An experimental investigation of these 3 types of commutators denotes their'
respective advantages and shortcomings: Advantages: Type (1) - simple design;
permits the use of stock types of step-by-step switches; type (2) - relative freedom
from noise; type (3) - total freedom from noise. Types (1) and (2) - direct voltage
commutation with a transmission coefficient equal to 1 in all channels; type (3) -
elevated commutation rate. Type (1) - commutator can be stopped at any step of the
switch; type (2) - can operate with the ordinary 307 (E07) indicator; type (3) - no
mechanical contacts, no rotation. Shortcomings: Type (1) - requirement for an in-
dicator with proloncred image persistence; type (3) - awkward design if ordinary
electron tubes are used for the commutation with a larcre number of points; types
(1) and (2) - requirement for mechanical contacts and rotating parts; type (3) - need
for equalization of the constants of the component gates and of the amplification
according to channels to prevent a scatter of circuit and tube param@ters when
tubes are replaced; type (1) - significant noise effects during the m@tion of the
switch. All three types do not permit the reading of voltages when the latte-i vary
with a frequency that is close to the scanning frequency. There are 6 figures.

angles are reptesentcd by voltages, or c.m.f.'s, and
the bending moments by currents, It is easy to sw

PERIODICAL: Elektrichestvo, 1957, Nr 8, PP 44 - 46 (U.S.S.R.)
ABSTR.ACT: A method is proposed, by which the calculation of a certain
class of electric circuits can be carried out not only without
a joint solution of large systems of equations, but also with-
out a substantial transformation of the circuit. A solution in
a general form cannot be found by this method, but the numerical
values of current intensities can be determined. The method
pi@opsed here is more complete than that proposed by O.M.BOGATYREV
(-'@'laktrichestvo, 1954, ITr 2), since an analytical solution,can
be found here and therefore a greater accuracy of calculation
can be obtained. It is true that the method is intended for
direct current here, but it can also be used for the calculation
of alternating-current circuits, namely for linear circuits
and, in form of an approximate calculation, for non-linear
circuits. An example is calculated.

solve non-linear algebraic equations by the iteration method. The method is
ill-,;strated byi 1) a calclalaTIon of the quality of a transient process in a
