TITLE: A perfected instrument for the determination of the vulcanization
kinetics of rubber mixtures
PERIODICAL: Kauchuk i rezina, no. 9, 1961, 31 - 32
TE)U: A description is given of the Soviet-made vulcameter, based in prin-
qiple on the vulcameter manufactured abroad [Ref. 1: 1. Peter, W. Heidemann, Kaut-
schuk u. Gummi, 10, WT, 168 - 172 (1957); 11, WT, 159.- 161 (1958); Ref. 2: R.
More, S. H. Morrele, A. R. Payne, Rubb.,J. a. Intern. Plast., 136, no. 23, 858
(1959); Rev. Ge'n. du Caoutchouc, 36, no..7 1001 (1959)]. The Soviet machine
determines the optimum of vulcanization of various rubber mixtures and records
curves of the vulcanization kinetics at various temperatures [Ref. 3: Author's OK
certificate no. 134069. Byull. izobreteniy, no. 23, Standartg1z, 1960]. The basic
difference of the Soviet model is in the construction of the measuring device of
the shifting force and in the method of sample fastening. The instrument consists
of a clamp adjustment with an eccentric cable, recorder of force with automatic
recording and a thermostatic attachment (Fig. 1). Samples 1 and 2 (30 x 25 x 2 mm)

are mounted between the upper (3) and lower (4) clamps. The upper clamp is made
of two parts, which move in a horizontal direction by means of a two-way screw
(11). The hollow clamps circulate the heat carrier. The temperature range is
determined by the type of thermostat (in this case it is the Bobser Ultrathermo-
stat). The cam 5 creates the sign-changing deformation of the samples rotated by
the motor 7 through the reductor 6 (mounted on the:back wall. of the instrument).
The cam brings the upper clamp into-motion with a constant amplitude equal to -
0.2 mm and a frequency of I cycle per minute. The shift force is fed to the mea-
suring device through the stationary lower clamp 4, consisting of a hydraulic dy-
namometer 8 with a manometric tube 9. The magnitude of the membrane shift of the
dynamometer or the lower shift at a maximum permissible load of 20 kg does not
exceed 0.03 mm. The automatic recording of the test results is performed by the
automatic recorder 10 which permits only maximum shift forces of the deformation
cycle to be r6corded. An electromagnet is used to record the forces in the maxi-
mum positions; it is synchronized with the cam of the cable. Thus the instrument
is able to record the change kinetics of the shift force in heating. The produced
curve characterizes the relationship of the shift force to the time (Fig. 2). The
instrument can also be used for determining -the duration of the mixture softening,

zatlon. The simplicity of the contivotion and saving of the rubber mixture has
proven the expediency of the instrument and the method used, and they are recom-
mended to all rubber plants and scientific research institutes. Tb-~re is 1 dla-

TITLE: - Purfurhydramide and its vulcanization activity
PERIODICAL: Kauchuk i rezinap' no. 2, 1961, 25 - 29
TEXT: The Soviet rubber industry uses diphenylguanidine as a nitrogen-con-
taining accelerator with a basic natur~e. Its production is based on toxic and
inflammable materials (aniline, carbon sulfide, lead allicagels and isopropyl al-
cohol). An attempt was made to find a cheaper nitrogen-containing organic base.
Furfurhydramide was tested in combination with sulfur accelerators as an acceler-
ator of vulcanization. A method for producing the furfurhydramide from cheap and
accessible raw material was developed. It is an nitrogen-containing organic base
which can be used as a vulcanization accelerator in combination with altax, captax
or thiuram. In mixtures based on natural rubber and a series of synthetic rubbers
containIng diphenylgua,.-,:.ne in combination with a~tax or captax, furfurhydramide
can be used instead of diphenylghanidine. It increases the durability of the

vulcanizates in repeated deformations. When it Is used in combination with cap-
taxj altax or thiuram In mixtures based on natural and a number of synthetic rub-
.i bers, the rate of vulcanization does not change and vulcanizates are obtained
with satisfactory technical properties. Its use extends the assortment of vul-
canization accelerators and decreases the consumption of captax, altax, diphenyl-
guanidine and thiubam. Its physical and chemical characteristics aret. finely
crystalline powder of straw-yellow color with dv 1-15 - 1.16, melting point when
crystallized from ethyl ether 117 - 1180C. It is easily soluble in methyl, ethyl
and isopropyl alcohol, acetone, ether, benzene, but is insoluble in water. The
molecular heat of combustion at P = const. is 1,828.15 cal, at V - condt. it is
1,847.87 cal. Acids decompose it to furfurole and ammonium, when boiled In di-
luted alkali it is converted to the isomer ba se furfurin. 'It absorbs ultraviolet

Commercial furfurhydramide melts at 110 - 1150C- Its nitrogen content Is 10.41%
calculated and 10.20 - 10-30% found. Obtained data showed that when natural rub-
ber is heated in the presence of furfurhydramide and sulfur, there is a signifi-
cant decrease of the plasticity, whereas the plasticity of natural rubber con-
taining only sulfur or furfurhydramide hardly changes at all when heated under
the same conditions. It is concluded that furfurhydramide strengthens the struc-
turalizing effect of sulfur. It does not affect the Inclination of the mixtures

TEXT: The authors report on the synthesis of the salts of titanyl oxalic
acid H 2(TiO( C204)2) .21120 with bivalent cations, and on the physico-
chemical study of the decomposition of these salts on heating. For this
purpose, the authors developed special methods., and produced, with their
aid, barium-, strontium-, lead-., and calcium-titanyl oxalates., For the
first three oalts, they used the followinL~ procedure: Concentrated
solution of oxalic acid was added, under continuous stirring, to the
aqueous solution of TiCl 4 (con,2entration 0.2-0.3 9/m1) which had been
prepared by the method described in Ref. 3. Aqueous solutions of barium

chloride, strontium chloride, or lead nitrate viere added to the resulting-
solution of titanyl oxalate at room temperature. The resulting complex
salts yielded a white precipitate. Calcium-titanyl oxalate could only
be obtained in acetonic solution. An analysis of tiie compounds produced
showed the following compositions: BaTiO(C 2 04)2' 4H2 0; SrTiO(C20 4)2.5,5112 0;
PbTiO(C 204)3' 4H20, and CaTiO(c 204 )2'5H2 0. By an X-ray phase analysis and
a crystal-optical investigation, the authors proved that the complex salts
obtained consist of small isotropic crystals. A comprehensive thermo-
graphic and thermogravimetric investigation showed that the thermal
decomposition of the said four titanyl oxalates proceeds by steps, and is
accompanied by several endo- and exothermic processes (Fig. 1). From the
character of decomposition, the authors conclude that the oxalate groups
are mainly bound to the titanyl ion; the cation has no noticeable effect
on the stren-th of this bond. The process of thermal decomposition is
concluded at about 8000C., The end products are meta-titanates of the
corresponding metals. Table 1 gives the specific gravities of the salts
used and of the products of thermal decomposition. As was expected, the

TEXTs Numerous articles have been published on the subject of accelerat-
ing the mastication process both of natural and synthetic rubbers by using vari-
ous organic compounds, such as mercaptanes, amines, nitro-compounds, nitroso-com-
pounds, guanidines, etc. The present article deals with the different methcds of
obtaining them and the results of a comparative study of the action of dibenzoyl-
sulfide and zinc thiobenzoate, which were the first substances to be recommended
by the authors as accelerators (Ref. 4) in the mastication process in natural and
synthetic [CkC-30 (SKS-30),6 CkH-26 (SKMN-26)]LIfubbers. The effect of these two a,:--
celerators on the properties of the mixtures bnd vulcanizates were compared to
Renacite IV and Peptone 22, two mastication accelerators used extensively In oth-
er countries. Dibenoylsulfide and thiobenzoate are non-toxic and are more easily

and simply to obtain than Renacite IV and Peptone 22. Diber=ylsulfide has also a
higher activity. Other chemical properties of the latter compound are listed
(Ref. 6). The synthesis of dibenzoylsulfide for this study is outlined and the
obtained product described in detail. Thiobenzoate was obtained from sodium thID-
benzoate and zinc sulfate by means of a mutual exchange of the salts in an aque-
ous solution (Formula 1). The laboratory procedure is explained (Formulae 2, 3
~md 4), and the experimental results discussed. It was seen that dibenzoyl3ul-
fide as a mastication accelerator of natural rubber, on the rollers and in the
rubber mixer, surpasses Renacite IV, Peptone 22 and zinc thiobenzoate. it also
accelerates the thermomastication of SKS-30 and SKN-26. Zinc thiobenzoate as an
accelerator of mastication of natural rubber is equivalent to Renacite IV and
Peptone 22. Dibenzoylsulfide and zinc thiobenzoate just as Renacite IV and Pepto-
ne 22 have no effect on the properties of raw mixtures and on the physico-mechan-
ical properties of the vulcanizates. Mass production of dibenzoylsulfide and
zinc thiobenzoate should be started, since they are simple to manufacture and
have a high activity as accelerators of rubber mastication. There are 8 graphs,
4 tables and 6 references: 4 Soviet and 2 German.

TITLE: News About the Thermography of Gibbsite
PERIODICAL: Doklady Akademii nauk SSSR9 1959, Vol 127, Nr 6, pp 1280 - 1282
(USSR)
ABSTRACT: The problem of an endothermal peak of disintegration of the
monohydrate - boehmite - (500 - 5500), occurring besides the
principal peak of dehydration (300 - 3500) in the thermograms
of gibbeite, has not yet been clarified. The most probable as-
sumption was that the boehmite in well crystallized gibbsits
can originate by crystal dehydration due to an increase in
steam pressure in some places (Refs 10,11). The authors tried
to check this assumption by experiment. They started from the
presupposition that there must be a certain dependence between
the dispersion degree of gibbsite and the value of the boehmite
peak on the thermogram of the former. Thus, it would be suffi-
cient to compare the thermograms of differently line pulver-
ized gibbsites under equal conditions. Gibbsite from the
Zhuravlinskoye deposit in the South Ural was used for this
Card 1/2

News About the Thermography of Gibbsite SOV/20-127-6-38/51
purpose. Figure 1 shows the results. The thermograms proved
to be peculiar in various respects: a) Concerning the boehmite
effect, the thermograms show that it actually disappears when
the crystals are pulverizedp which confirms the assumption of
reference 10. The dispersion degree of gibb8ite exerts a very
E:trong influence on the character and intensity of its phase
transformations on heating. This contradicts the usual ideas
(particularly of Ref 1). X-ray photographs at 400, 700 and -
10000 did not produce the desired results. The authorsf how-
ever, were able to find similar data iri publications (Ref 1)
concej~ning some silica-hydrate gels. Further investigations
seem to be necessary. There are 1 figure and 15 references,,
5 of which are Soviet.

ABSTRACT: The transmission of a parameter t-aking on a continuum of values (6*.g.,
code transmission of measurands) is considered. The problem is considered of
optL-uzation of a decision algorithm at the output of an information-transmi-sion
system for a fixed law of quantization of the message at its input. A case of mean-
square error serving as a criterion is examined as an example. Optimization of
quantization is reduced to an algorithm calculated on a digital computer. Estimated
results show that the optimal quantization and optimal decision algorithm permit
cutting do,,m the mean-square error of transmission by 20-500 for a signal-to-noise
power ratio under 2. Transmission of a parameter by error-correcting codes is
considered. N. S. [Translation of abstract3

TITLE:- Reconditi~ni f Machine Parts by Metal Plating (Electric Metal Plating in

PERIODICAL- Tekhn.-ekon. byul. Sovnarkhoz Amursk. ekon. adm. r-na, 1958, Nr 2, pp 26-27
ABSTRACT-,. The author investigates a new method of reconditioning machine parts of
steel and cast iron by cold vibrocontact facing of metals and hard alloys
in an electrolyte jet. The advantages of this method are: 1) the metal
is brought onto the cold machine part, therefore no annealing, no IoVer-
ing of mechanical properties, etc take place, which occur in facing with
the aid of a gas flame. 2) the method ensures a stable adhesion to the sur-
face of the machine part reconditioned. 3) the method is more simple, less
Card, 1/2 expensive and more harmlesz than the galvanic method of reconditioning ma-

TEXT: The Leningrad branch of the Vsesoyuznyy proyektno-tekhnologicheskiy
institut tyazhelogo mashinostroyeniya (All-Union Technological Planning Institute
of Heavy Machinery) has designed a copy grinding machine for the tooling of tur-
bine blade profiles. This machine was built by the Leningradskiy metallicheskiy
zavod im. Stalina (Leningrad Metallicheskiy Plant im. Stalin) in 1959. The machine
housing is a welded plate-steel structure with a coolant container inside. The
housing is mounted on a cast iron base plate and houses also the coolant pump.
Spindle stock 2, representing a two-arm lever, is mounted on two antifriction
bearings 1. Cast iron plate 4 is fastened to welded stock housing 3. The spindle
carrying grinding wheel 5 Is mounted on antifriction bearings. The spindle is ac-
tuated by a 10-kw electromotor through a V-belt drive. Copy roll mechanism 6 with

a diamond pencil can be displaced in vertical and horizontal direction and along
the ci-rcumferential curve. For the dressing of the wheel by a roller the machine
is equipped with additional drive 11 consisting of a 0.6-kw electromotor, worm
reducer with a gear ratio of 1:30, free wheeling clutch and V-belt drive. The
vertical displacement of the bracket with the diamond pencil is kinematically con-
nected to the vertical displacement of the copying roll, so that a reduction in
diameter of the grinding wheel after each dressing is compensated for by a read-
ju~tment of the copying roll. The copying roll slide can be displaced indepen-
Uently by the hand wheel 12, which is used when turbine blades with big allowances
are machined, requiring more than one pass. The grinding machine is equipped with
pneumatic cylinder 1_3 for swivelling the spindle stock when the workpiece is set
or the ready turbine blade is removed, or when one template Is replaced for aR-
other. Rocking table 14 is mounted in front of the machine bed. To reduce the
inertial force the table body is cast of silumin. On the bedways of the rocking
table, upper silumin table 16 is mounted carrying two rockers 17. One rocker is

TITLE: A Copying-Grinding Machine for Machining Turbine
Blades of Varying Profile
PERIODICAL! Energomashinostroyeniye, 1961, No. 3, PP. 32-34
TEXT: The most complicated operation in blade manufacture
is grinding the blade profile. Until recently, at the Leningrad-
skiy metallicheskiy zavod (Leningrad Metal Works) and other turbine
manufacturers this operation has been carried out manually. The
work is heavy and the metal is annealed locally because the
pressure applied to the grinding wheel is uneven. In recent years
many attempts have been made to mechanize the operation. After
prolonged experimental and development work, the Leningrad Metal
Works (LMZ) has developed two machines for grinding large turbine
blades of variable profile. One of these machines was designed by
the Leningrad Branch of VPTI (Designer M. A. Borukhzon) the other
was developed at the IMZ; both give good and stable results.
Deviations permitted from the theoretical profile do not exceed

0.1-0.15 mm. The copying and grinding machine designed by the
Leningrad branch of VPTI is based on mechanical copying of a model.
The main feed of model and blank is provided through a special
drive and distribution mechanism and the profiling feed is derived
from the pressure of the model on a copying roller. The grinding
is performed in transverse strokes and transition from one stroke
to the next occurs on the overrun. Outline drawings of the machine
are given in Fig. 1 and a detailed description of the mechanism
is given. The copying roller 10 bears on the model 11 which
operates on the grinding wheel 3 cutting the blank 2. The special
drive 17 is provided for trimming the grinding wheel with an
industrial diamond. The principles of operation are described.
The method of grinding blades is illustrated in Fig. 2 the initial
position of the blade and grinding wheel is shown in Fig. 2a.
Blade section 1-2 is ground by rotating it round an axis, as point
2 is reached the cam mechanism arrests rotation and starts
displacing the table so that the section 2-3 is ground. The feed

is maintained constant to ensure evenness of finish by appropriate
profiling of the cam. The cam is displaced relative to the blade
whilst on the overrun section 3-4. Blades up to 780 mm, long can
be ground, the maximum diameter of the grinding wheel is 400 mm
and the least diameter 320 mm. The number of double strokes of
the operating table per minute is 7.5-45, the grinding wheel runs
at a speed of 1440 r.p.m. and the overall dimensions of the
machine, length, width and height are 2670 x 2140 x 2800 mm. A
defect of the machine is that the grinding wheel wears during the
process of grinding and this causes some error in the blade profile-
The machine developed by the IMZ is then described, it is a special
machine Type IC-q6 (IS-96) of the "Stankonstruktsiya" Works which
was modernized and made into a semi-automatic copying machine for
grinding the backs of variable profile blades. The modernization
consisted in reconstructing the polishing head and developing a
device for turning the blade and model, in providing an oil
cooling system and other minor reconstructions. An outline drawing

of the machine is given in Fig. 3 and the construction is briefly
described. It can deal with blades up to 760 mm long at a cutting
speed of 25 m/sec, the table being displaced at a rate of 3250
mm/min. This machine has an abrasive belt which can make a cut up
to 1 mm deep. The feed is controlled by a copying roller acting
on the model. The amount of cross-feed depends on the shape of the
blade and ranges from 1.5 to 4 mm. The pressure of the belt on the
modelis constant at 10 kgq the working part of the belt is 25 mm
wide. The machine time for grinding a blade is 15-20 minutes
depending upon the length and shape. A copious supply of cooling
oil is provided during the grinding operation. The abrasive belts
have a linen base with white electro-corundum of No. 46 grain size7
The accuracy of the finished profile is within 0,1 mm over the
length of the blade, This method of grinding has a number of
advantages, it is very accurate, a good class ? finish is obtained.
The metal that is left on the blades after milling, 0.5-1 mm is
removed in a single operation. The main difficulties with the

machine are inadequate stability of the grinding belts.and the high
consumption of oil which must be frequently replaced because of
contamination with cuttings and abrasives. Cooling with emulsion
type lubricants is required and water resistant belts are needed.
However, the use 'of automatic grinding has reduced the i,.ianufactur-
ing costs and improved turbine efficiency. A full range of
grinding machines for turbine blades should be developed. There
are 3 figures and 3 tables.
