ABSTRACT: The author examines the problem of the evaluation of the effect
of the flexure of the floor plates, also that of the effect of the
stiffening ribs attached to the floor plates, upon the Eulerian
load on the bottom plates, The effect of the flexure of the floor
plates is studied as a problem of the stability of a strip-beam
that is elastically fixed on terminal and intermediate supports,
corresponding to the fastening points of the floor plates to the
bottom plates, and which become unstable on a cylindrical
surface. The problem is solved by means of the angular de-
formation method, The most significant effect on the Eulerian
load on the bottom plates is exerted by the stiffening ribs

account. Calculations show that this effect introduces an increase in the
Eulerian loads on the bottom plates by more than 100 percent. It is shown
fli-,jt stiffening ribs on floor plates installed in general practice (without
calculation) have a rigidity significantly in excess of their critical rigidity
arld that their effect on the Eulerian load on the bottom plates can be accounted
for with the aid of the calculation formula provided in the paper.

TITLE: On the Problem of Stability of Coverings and Plates With Con-
sideration of the Torsional Rigidity of the Rafters (K voprosu

PERIODICAL: Tr. Leningr. korablestroit. in-ta, 1956, Nr 18, pp 13-22
ABSTRACT: At first the stability of a covering consisting of a large number
of identical, equally spaced, longitudinal beams supported by a
row of identical, equally spaced frame rafters is examined, as
well as the stability of a plate stiffened by transverse rafters
only, wherein consideration is given to the torsional rigidity of
the transverse. beams (rafters). It is shown that in either case
the problem resolves into two individual problems, namely, 1)
the problem of the oscillation of the rafters and 2) the problem
of stability of a bar resting upon equally spaced elastic supports
of specified rigidity, which constitute a fixed elastic attachment
for the bar wPh a certain coefficient of yield. This coefficient
turns out to be a constant all along the length of the rafters
only in cases of freely supported rafter ends. Then the prob-

On the Problem of Stability (cont.
is investigated relative to the problem of the magnitude of the critical flex-
ural rigidity of the rafters... The slope-deflection method is used in solving
the problem. The equations of stability are obtained from the conditions of
the equilibrium of the supports and the equating to zero of the sum of the
moments and the transverse forces. In drawing up the equations the author
borrows the ready expressions obtained by P. F. Popkovich for the bending
moments and the transverse forces produced by the sagging and slope deflec-
tion of the supports and also the tabulated functions of the values of AM,
B(u), and C(u), where u = V2 1*4-r-7ffi. The determination of the argument
from the equations of equilibrium enables 9ne also to find the Eulerian value
of the compression force T = (Zu)?Ei/ 1 , as well as the parameter char-
acterizing the cricical rigigity of the elastic supports. The investigation is
conducted for cases where the number of spans of the bar is equal to 2, 3.
and infinity. The results show that intermediate supports have a critical
flexural rigidity value only for bars with two and an infinite number of
spans while, at the same time, the rigidity increases with an increase in
the elastic restraint of the supports. It turns out that for bars having three
or more spans a critical rigidity value of the supports does not exist and that
only perfectly rigid supports allow the full use of the increased Eulerian
loading which can be obtained from the elastic restraint. It is noted that the

influence of the torsional rigidity of the rafters upon the stability of the
coverings and plates of realistic dimensional ratios is found to be quite in-
significant and amounts to only a small percentage. .

PERIODICAL: Tr. Tsentr. n. -i. in-ta morsk. flota, 1957, Nr 9, pp 15-21
ABSTRACT: Stability- analysis formulae are derived for two continuous
beams resting on equidistant supports and connected to each
other at the center of their respective spans by a rigid cross
brace; the interrelation of the compressive forces acting on the
beams is considered given. This problem arose in connection
with current design practice with respect to the longitudinal
bottom assembly of transport vessels. In addition, stress-anal-
ysis formulae are given for this same beam system, and the
question is examined as to which requires the thicker beam,
design for strength or design for stability.

ABSTRACT: The sodium salts of the above acids are widely used as
emulsifiers,, detergents, and wetting agents. The surface-
active tension of salts of sulphonic acids was investi-
gated; results of tests on the Investigated fractions
are given in a table. The surface-active tension of
aqueous solutions of the emulsifyinq agent were determined
on the Dyu-Nui apparatus at 200 - 2 OC with the aid of
a lamp potentiometer LP-5 with a glass electrode (Fig.1).
The sulphur salts of petroleum contact acids have a lower
critical concentration of micelle formation than the
sulphur salts of gas-oil contact acids. The pH of the
solution of the emulsifier influences,tc a certain extent,
the surface-active tension. A small Increase can be

active properties Qig.3). The surface-active properties
of the solutions decrease considerably in the presence
of hydrtoarbons (Fig.4).. Further tests were carried out
on the variation of the pH in relation to the'concentra-~
tion of the solution of the emulsifier (?1 5) The
variation of the pH of solutions of collof~aleelectro!YtQS
dependent on the concentration as well as the ohange in
the physical properties,point to a complex structural
change which Is linked with an alteration in the dimension
and form of the mioelles (Ref.6). Investigations by
N. Sata (Ref.7) are discussed. Solutioz,~ of high-molecular
fractions show a higher degree of surface-activity than
solutions of low-molecular fractions. The authors also
conclude that a marked change of the pH occurs when
electrolytes are added. Intermittent changes of the pHp
depending on the concentration of the colloidal electro-
lytes are connected with the critical concentration of
the micelle formation. There are 5 Pigures and 1 Table

1E)(T; The effect of the phosphorous atom on polyme-r properties was in-
vestigated and a comparison was made of the sodium-butadiene and acryl rubber
properties with those of similar polymers containing phosphorous in the side
chain. The ethers of allyl-, butadiene-, isoprene -styrene -phosphene acids were
used as the phosphorous -containing monomers in the experiments. The 03H- Yj
(FEK-M) photocolorimeter was used to determine the phosphorous content in the
initial products and polymers. The introduction of the phosphorous atom into the
polymer chain of the sodium-butadiene rubber was found, in most cases, to improve
considerably the physico-mechanical properties of the vulcanizates at low temper-
atures, as compared to the sodium-butadiene rubber produced by the emulsion meth-
od. The properties of the acryl polymer were considerably improved at low temper-
atures upon introducing 1% of phosphorous into the polymer. The following con-
clusions could be drawn: the ethers of the unsaturated phosp1hene acids copolymez-

TITLE: The problem of the vulcanization mechanism of acryl rubber
PERIODICAL: Vysokomolekulyarnyye soyedineniya, v. 4, no. 1, 1962, 3-8
TEXT: The reaction mechanism of vulcanization of acryl copolymers by polya-
mines and sulfur was clarified by experiment. It was f6und that 1) sulfur
alone does not cause vulcanization of the copolymer of butyl acrylate with
acrylonitrile in an N 2 atmosphere at 1500C. Vulcanization can, however, be
conducted with polyamines alone or with polyamines + sulfur, S accelerating
the reaction. 2) The radioactivity of films of acrylonitrile + ethyl
acrylate labeled with c14 in the ester group did not change after vulcani-
zation with polyamines and S (4 hrB at 15000, Consequently, no alcohol
formation, i. e., no Claisen condensation takes place. The vulcanizate was
insoluble in organic solvents. 3) No amide bonds were detected by infrared
SDectroscopy in the final product of the reaction of butyl isobutyrate with
polyamines (10 hrs at 15000. 4) Polybutyl acrylate, which cannot be vulcin-
ized with polyamines alone, forms a regular vulcanization network on addi-

tion of acrylonitrile. The number of cross links rises with increasing
content of acrylonitrile (2.98-1019 cross links at 30% acrylonitrile) 5)
The viscosity of solutions of rubber from the copolymer of butyl acryiate
+ acrylonitrile does not change if vulcanization with polyamines is carried
out in an NO atmosphere instead of in N 2. This indicates that the reaction
between nitrile groups and polyamines has a molecular nature. 6) A 5% solu-
tion of the copolymer could be vulcanized after adding 2% polyamine and 0.5%
S. Gel formation occu=ed in an N 2 atmosphere but not in NO. Consequently,
radical processes occur in the presence of S. 7) The rising content of
acrylonitrile in the copolymer with butyl acrylate does not influence the
amount of bound sulfur (approximately 20% of initial S). The copolymer is
~ genuine insoluble vulcanizate, whereas polybutyl acrylate does not form
~ network at equal sulfur content and remains soluble. 8) Polyacrylonitrile
or polybutyl methacrylate vulcanized with S contains less bound sulfur
(5 - 6% and 8.6%, respectively), and polyisobutylene only 5.5%. Cawlmions'; a)
Vulcanization of the copolymer of butyl acrylate and acrylonitrile with

TITLE: Aging of acryl rubber
PERIODICAL: Vysokomolekulyarnyye soyedineniya, v. 4, no. 1, 1962,
9 - 12
TEXT: The structural changes occurring in the aging of acryl rubber were
studied by determining the number of cross links and the content of total
sulfur. Acryl rubber, (0.5% S, 0-5 - 3% polyamines), vulcanized at 1430C,
was heated at 2000C for five days. It was found that (1) heating in an N 2
atmosphere did not change the number of cross links; (2) the number of
cross links rose when acryl rubber was heated in air. The increase of the
number of cross links was greater at a high content of polyamines: at 1%
polyamine the number of cross links was 0.3341019 before, and 6.30-1 ?19
after heating; at 3% polyamine it was 4.15-1019before, and 32.30,10 9
after heating. Polyamines accelerate catalytically the oxidation process.
(3) The total content of S is hardly changed by heating, and the content of
bound S decreases. It is assumed that polysulfide bonds are converted into
Card 1/3

S/190/62/004/001/002/020
Aging of acryl rubber B101/BliO
more stable di- or monosulfide bonds. An addition of 0.5 g-mole of iron
naphthenate per g-atom of S reduces the content of total sulfur. (4) The
number of cross links decreases with rising sulfur content and constant
content of Polyaminest at 0.5% S, it is 0.25'1019 before, and
2.62-1019 after heating; at 2.0% 5, it is 0.40-1019 before, and 1.78*1019
after heating. Sulfur therefore acts as a vulcanizer and prevents oxidative
aging processes. (5) Vulcanizates labeled with C14 in the ester group
showed a decrease in activity by 5% after 20 days'heating at 17500. This
value surpasses the experimental error (1%). The loss of actiLrity is
attributed either to the formation of active alcohol due to Claisen conden-
sation or to the formation of amide bonds. Non-vulcanized copolymer loses
its activity more quickly than a vulcanized one. Consequently, the vulcan-
ization network complicates the condensation process. A. S. Kuzlminskiy
and A. L. Klebanskiy are mentioned. There are 2 figures, 3 tables, and 7

ABSTRACT: This article is a continuation of the author's previous paper concerning
the determination of macroscopic quantities of a mechanical system consisting of a
great number of interacting particles (Vestnik Moskovskogo Universiteta, Seriya
Mlathematika, Mekhanika, v. 2, 1966). Expressions are obtained for macroscopic
qu,3ndtLes of the system, such as density, stress, heat flow, and internal energy.
The corresponding transfer equations for thesequantities are derived from Vlasov's
generalized kinetic equations and from new kinetic equations by using Fisher's

TITLE: Study of the properties of polyaorylamide by the method of light
scattering
SOURCE: Zhurnal prikladnoy khImII, v-38, no.11, 1965, 2533-2537
TOPIC TAGS: nitrogen compound, light scattering, polymerization
ABSTRACT: The object of the work OILS to establish a relationship be-
tween the characteristic viscosiir...7,4 , and the molecular weight, M, for
high molecular weight polyacrylaml .do using the method of light scatter-
Ing for determination of the molecular weight. Polymerization of the
acrylamide was carried out In an oxidation-reduction system In an aque-
ous medium in the presence of 0.5% potassium persultate, 0.25% sodium
hydrosulfate, and 0.14% triethanolamine,, and In the presence of atmos-
pheric oxygen. The polymerization.7 qjx6rature was 500 for the first two
hours, and then 600 f_o_r_e_1_g-FtFYo-ur~// &'ke polymer was obtained as an 8%

aqueous solution. After dilution to 1%, the PoXyaorylamide was proolpi.
tated with acetone and dried in vacuum at 500. The yield was 97%. The
product was a white slightly hygroscopic powder readily soluble In water
Fractionation was done by solution in formamide, and 8 fractions were
obtained. Measurement of the viscosity and the light scattering of the
solutions was done at 200. To avoid ionization, the measurements were,
made in a 10% aqueous solution of sodium chloride. Viscosity was mea-
sured with an Outwald viscometer with a flow time of 110 seconds for the
solvent. The light scattering was measured on a "Sofika" photoelectric
turbidometer and the results were interpreted by the method of double
extrapolation. The measurements were carried out in a range of angles
from 30 to 1500 and at polymer concentrations of 0.20-0.65 and 0.03-0.10
for the low and high molecular fractions, respectively. The results are
exhibited in tabular form. A plot, on a log-log scale, shows the depend
ence of the characteristic viscosity on molecular weight. Results are
said to agree closely with previous results obtained by determination of
the molecular weight by cementation and diffusion. Orig art. has: 8 for
mulas, 2 Afigures, and 2 tables.
