TEXT: This is a description of the mathematical apparatus of programming
for oomputers whose computing elements perform addition and substraction (additive
machines). The matrix calculus is the mathematical basis of this apparatus.
Many of the facts, established f6r additive machines by means of the matrix ap-
paratus, can be applied to machines of any type. Command and program operators,
input operators and program cycles (homogeneous and inhomogeneous ones) are con-
sidered. A definition of the homogeneous computing problem is given and con-
ditiDns of programability of its solution by a homogeneous program cycle are
formulated. It is shown that the problem can be programmed on a given machine
if functions obtained in the machine coincide with the sought for functions in a

certain given beforehand set. An example of using the programability conditions
for solving a homogeneous computing problem by an inhomogeneous program cycle is
considered. Possibilities of widening the class of operators solvable by program
cycles are analyzed. The author gives a method of calculating the input function
which must be put into the machine and with which the solution of a problem
starts. The problem of programability of the solution of an Inverse problem
(negative powers of an operator) is considered. The possibility of solving an
inverse problem without inverting the operator Is established, which is im-
portant when a computing problem is given in an implicit form. Conditions are
discussed under which a simultaneous solution of several different computing
problems can be realized in a machine by means of one program cycle. There are
16 references.

In the paper are considered different methods of speedinf-up operations in
digital computers.
Methods of accelerating the digit by digit multiplication by overlapping in time the
operations of ad,41tion and shift; the method of the "travelling wave" when the addition
of several partial prodvets is affected simultaneously, etc.
For speeding-uO thedivision operation a method is recommended by which the infor-
mation contained in the c6de of the next remeinder is used for determininq in one step the
group of the quotient consecutive digits.
Are considered the adv,,,ntages, from the point of view of operation speeding-up, of
storage of codes in not normalized condition and representntion of negr-tive numbers in the
machine in reverse code (with Introduction of code feature). Combined methods of calcu-
lation of certain algebraic &Mrassions in the conditions of an arithmetic device with an
incressed number of OOMPOMItS.
Methods are described for 3peeding-up the addition elementpry operation, which
ensuke single-shot operation of each component of the add circuit, as well as the methods
of speeding up the group shift by means of a special shifter designed in the form of a
f errite matrix.
Considerations are given on the expediency of Including the calculations of the
values of elementary functions in the list of main machine operations, and sane algorithms
are given (which are adaptable for their circuit execution by the arithmetic device), on

The role of microprogram control for accelerating-- operations is discussed. In
particular, at microprogram control, when a single-si~ed high-speed lPrVe capacity
memory is used, it seems possible to obtain efficient results by calculatinr the
elementary function values on the basis of block -poly-nomial apprmtimation of functions

ABSTRACT: The author describes the results of 87 experimental

7 m to 22 m long in drill holes with diameters of 150

by sieve analysis and was evaluated by the percentage
of material remaining on the screen (Pn). The relation-

fracturing (CRF) was determined. Experiments were conducted to
determine the relationship between P and-the spacing of the charges.
When the length of charges were 7 m ~o 22 m, for a constant value of
(CRF), only the index measuring the spacing of the charges varied,
and for these experiments this index amounted to 0.6 to 1.0 times
the value of (CRF). The relationship between (CRF) and the length
of charge was also shown by experimental explosions indicating that
it is possible to determine the necessary value of (CRF) in respect
to the diminution of length of charge so as to produce a minimum of
coarse particles. An analysis of the results leads to the following
conclusions. With an increase in the value of (CRF), there is a
.considerable increase in the coarse fraction. The greatest crushing
1s obtained when the charge spacing is within the interval of 0.6
and 0,7. The size of the drill hole shows no relationship to the
amount of rock crushing. 'The minim= size of'the hole which still.
elimates ledges at the bottom of the charge depe-nds on the value of
(CRF) and is about equal to 0.2 W. The optimum value of the coef-
ficient of compaction (k) occurs within the limits of 0.8 (CRF) to
1.0 (CRF). To obtain the minimum coarse fraction it is necessary

Equipment similar to rubber masticators has been designed for
breaking down plastics by the exertion of mechanical force,, so that
the fractional parts of chain molecules which are then formed and
which possess the properties of free radicals may react with other
chain molecules or parts of chain molecules, forming block polymers,
or combine with monomers., forming grafted polymers. The equipment in
question consists of two circular corrugated plates between which the
material is triturated when the lower plate is rotated against the
upper plate that remains stationary. Two different types of plates
are described: one has a rectangular groove vith the contour of an
Archimedes spiral and a depth gradient and the other a groove which
possesses the same contour but exhibits a uniform depth and is cut in
such a manner that a ridge with a profile corresponding to that of a-
Whitworth screw winding results.

The first type of. pUte vas found to be best suited for the
copolymerization of low-molecular brittl e resins with elastomers
and the second for combining different types of elastomers with
each other. By applying the method of mechanical disintegration,
block polymers representing combinations in different proportions
of nitrile rubber with phenol-formaldehyde novolacs, epoxy-resins,
and refined coal-tar pitch were obtained. The time required for
the experimental preparation of the block polymers was 4-5 minutes.-
Samples weighing 10-20 g were used., and the mechanical disintegra-
tion was carried out in an atmosphere of inert gas. .
The authors conclude on the basis of the results described by
them that the mechanical method of producing block polymers and
grafted polymers is superior to chemical methods. They add that an
,appar&tus for the continuous production of block polymers and
grafted polymers by the mechanical method is being developed at
the Scientific Research Institute of Plastics, and that the avail-
ability of this apparatus will make possible the industrial produc-
tion of such polymers by the method described.

The authors of the article exp !--in the significance of the work
on block polymers as follows:
"At present requirements of a complex nature are put in various
branches of the industry to products made of high-molecular compounds.-
These requirements comprise superior heat stabilii;y, improved mechan-
ical and dielectric characteristics, stability to the action of vatero
chemical stability, retention of the original characteristics aft-r
prolonged use of the products,, and stability at low temperatures com-
bined with a resistance to the action of gasoline and oil. However,
none of the available types of polymers can completely satisfy all
the requiruments mentioned above. For that reason it has become
necessary to combine different types of polymers in such a manner
that the materials resulting frizz their interaction vill possess all
~the desired properties," (U)

TITLEt Thermomechanical Investigation of Epoxide Resins (Termomekha-
nicheskoye issledovaniye epoksidnykh smol)
FERIODICALt Kolloidnyy Zhurnal, 1958, Vol. xx, # 1, pp 34-37 (USSR)
ABSTRAM Epoxide resins may be either thermoplastic or thermoreactive,
depending on the initial diphenyl propane and epichlorohydrine
components. Thermoreactivity begins at a molar ratio of
I s 1.5 of the initial components and at a further decrease of
the epichlorohydrine content. The thermomechanical curves of
the initial resins were obtained on a dynamometric scale. The
solidified specimens were measured on a consistometer. Epoxide
resins are low-molecular, i.e. they pass from the vitrified
condition into a viscous-fluid one. The vitrification tempera-
ture varies between 5-50 0C. Solidified resins are prepared
by using a hardening agent, polyethylenepolyamine, for 30-45
days. The reduction of the epichlorohydrine content to a
ratio of 1 1 1.2 and a 10-hour heating at 2000C produces the
resin type ED-15, which is elastic at increased temperatures.
Card 1/2 Resins with 10WOT numbers of epoxide groups are more elastic

at increased temperatures than those with higher numbers.
Thermoreactive resins, solidified without addition of a har-
dening agent, have a higher heat resistance and have a better
appearanos than those solidified by amines and resol resins.

TITLEs The Method of Heterogeneous Polycondensation
PERIODICALt Plasticheskiye massy, 1960, No, 2, pp. 14-17
TEXT: The authors *studied the possibi.lity of obtaining polyamides on the
interface, with and without mixing of the heterogeneous systems L. A.
Sakharova, S. A. Gershkokhen, and L. P. Nekrasova participated in the ex-
perimental work. Their results confirmed those obtained by V. V. Korshak
and correspond to the reaction mechanism proposed by him, at which a re-
action component present in abundance does not inhibit the reaction of the
end groups with other initial substances, so that the polymer chain con-
tinues to develop. If the polymer is formed on the interface as a film
which pre-rents further development of the polymer chaint the interface
must be continuously set free. This is done either by mixing the hetero-
geneous system or by continuous polymer extraction at the interface, the
latter process having been performed by means of the mechanical instal-
lation by M. P. Shapenko, which also permits to vary the extraction rate

from 0-5 to 12 m/min. Individual factors influencing the yield and
molecular weight of the polymers were also studied, e.g., the addition of
certain salts (Ref. 8) to the aqueous phase and of surface-active sub-
stances during mixing; an increase of the polymer yield up to 75-90% was
thus obtained, It was also found that a certain feed rate of the reagents
must correspond to a certain extraction rate. Polycondensation on the
interface took place at 220C + 20; an increase above 20 to 250C is not
suitable since the diffusion of the reagents increases. Polymers with
different physical and chemical properties are manufactured by the above
method, according to the initial componental i.e. diamine and diacid
anhydride. Phthalamides an(l polyamides without hydrogen bonds are of
interest, as well as the production of copolymers with given properties;
furthermore, polymers may be obtained on the basis of products such as
ethylene diamine, which at present is not used for the production of
high-molecular polyamides according to the homogeneous method. There are

Glass Textolite on the Basis of Polyvinyl Butyral
PERIODICAL: Plasticheskiye massy, 1960, No. 3, PP- 48 - 49
TEXT: -The authors report on their studies of methods of producing glass
textolite from polyvinyl butyral (PVB) with glass fabric of the type
ACTT (6) (ASTT (.b)),as-a filler. They used A-type PVB, and found that
PVB embrittles at high temperatures, and loses its elasticity and solu-
bility. Also its impac t strength decreases, whereas hardness and bend-
ing strength increase., At high temp *eratures, PVB decomposes, becomes
sticky, and its mechanical strength decreases. This was ascribed to a
change in molecular structure, which changes from linear to steric with
numerous cross links (Refs. 2,3). In glass textolite, the PVB content
dropped to 4% after impregnating the glass fabric with an 18% PVB solu-
tion after drying at high temperature. Glass textolite was produced for

experimental purposes a) by molding at different pressuresand b) by de-
formation in vacuo. The authors studied the effect of temperature, PVB
content, and deformation pressure on the properties of glass textolite.
They found that a change in the PVB content has no great influence on
the quality of glass textolite. A pressure of more than 45-50 kg/cm2or
howevery effects a decrease in strength with the use of most kinds of
resint probably due to destruction of the filler. It is shown that with
the use of PVB a much higher pressure can be applied, without d.etri-
mental consequences, than with the use of other resins. Further$ the
authors found that PVB glass textolite deformed in vacuo has a lower
strength than phenol glass textolite produced in vacuo. Experimental
results.show that the increased specific pressure endured by PVB
products improves their quality. The properties of PVB glass textolite
can be changed by additional heat treatment. There are 2 figures and
4 Soviet references.

TITLE: A Block Copo3ymer of Epoxy- and Dimethyl Resorcine Resins as
Binding Agent-for Glass-reinforced Plastics
PERIODICAL: Plastiche6kiye massy, 1960, No. 5, PP. 10 - 11
TEXT: This paper discusses a study of block copolymers obtained from
epoxy resins of the A-5 (ED-5) and 39-6 (ED_ 6) types, and dimethyl
resorcine resins. The epoxy resins were obtained from diphenylol propane
and epichloro hydrine in alkaline medium, and contained 18 - 20 rit of
epoxy groups. Dimethyl resorcine resin was obtained by condensation of
dimethyl resorcine with formaldehyde in the presence of mono- or polyValent
alcohols. A combination of 70 % epoxy resin and 30 % dimethyl resorcine
showed the best properties: Brinell hardness 30 - 34 kg/mm2, heat resistance
according to Vicat 115 - 1250C, compressive strength 1300 kg/cm2. Glass
fabric was steeped with the unhardened copolymer, dried at 70 - 600C, and
then pressed. The binding agent content was (~O�2)%. The resilience of
the textolite obtained was 350 - 400 kg.cm/cm its binding strength

TITLE: Production of Block Polymeraland Grafted Polymers by
Means of Spark Dischar e i a Liquid
.PERIODICAL: Plasticheskiye massy, 1960~ No. 6, ppc 2 5
TEXT: The authors report on experiments made with an apparatus ache-
matically shown in Fig. 1. Spark discharges were generated in a vessel
(Fig. 2) filled with the substances to be polymerizedl a shaping spark
gap was connected in series with the spark gap in the vessel. The con-
denser potential attained 60 kv, the energy stored was about 100 joulest
the discharge frequency was about 0.5 - 1.5 cps. The authors discuss the
effects of the spark (hydraulic and cavitation surgeg formation and re-
composition of,free radicals), as well as the influence of aperiodic
discharges on the transformation of electric energy into mechanical
energy. A solution of 15 parts by weight of polyvinyl chloride, 50 Parts
by weight of methyl methaerylate, and 100 parts by weight of cyclohexane

proved to be convenient for the production of grafted polymers. After
5 hours of spark discharges at 20OCp the authors performed a heating to
1000C, a precipitation of the oyclohexane and the methyl methaerylate
not having reacted by means of ethanol, and an extraction of the poly-
methyl methacrylate and the polymer with a low content of polyvinyl
chloridekk LP' by means of glacial acetic acid. The insoluble fraction
contained Pkknd grafted polymer with a high content of vinyl chloride.
A comparison with a solution not treated with sparks (Table) showed that
in this case the injpoluble fraction contained only 37 molecules of
methyl methaerylate'iper 100 molecules of vinyl chloride whereas in the
Fle r7ra-cri-on of a spark-treated solution 100 molecules of vinyl
chloride contained 63 molecules of methyl methacrylate. Thus, the yield
in grafted polymer was doubled. Block polymers were produced from
5% solutions of PVC and ethyl cellulose (1 : 1) in equal parts of ethyl
acetate + cyclohexane under the same conditions as the grafted polymers.
The chlorine content of the insoluble fraction was 45%. There are 2 fig-

Liquid Butadiene - Styrene Copolymers
PERIODICAL; Plasticheskiye massy, 1960, No. 10, pp. 6-8
TEXT: The results of experiments conducted for obtaining low-moleoular
butadiene-styrene copolymers are described. These copolymers were examined
for their usability in the production of thermosetting rosins. Divinyl and
styrene copolymers were produced by a method developed at the kafedra
sinteza polimerov MITKhT im. Lomonosova (Chair of Polymer Synthesis of the
Moscow Institute of Fine Chemical Technology imeni Lomonosov) (Ref. 10).
[Abstracter's Note: The method is not described here). The initiators used
were benzoyl peroxide, diphenyl ethane hydroperoxide, cumene hydwoperoxide.
The yield obtained under optimum conditions was 60-65% referred to the
monomers. The copolymer contained 20% styrene. The polymerization was
performed (a) in inert solvents (hexane, heptane, benzene) or in active

50-900C. The low-molecular copolymers obtained were examined for their
molecular weight, their double bond content, and their 1,4-bonds (by
means of perbenzoic acid), and their hardening capacity was tested at
130-1801C. The copolymers obtained by means of sodium (molecular weight
4000-6000, 21-23% 1,4-bonds) are hardened within 8 hours to form a resin
which is insoluble to 94%. The substances polymerized in emulsion
molecular weight 3000-i-5000) and in solution (molecular weight 1500-3000)
50-52%, 1,4-bonds) remained elastic after 40 hours of hardening and
~
contained only 83-90% of insoluble substances. The glass reinforced
plastics produced therefrom were resistant to humidity and had a breakdown
voltage of 18.9-32 kv m; bending strength of 1080 kg/cm2 and a Brinell
hardness of 8.9 kg/mm~m
. Epoxidation by means of peracetic acid or
perbenzoic -.aid yielded resins which contained 3-5.8% epoxide groups,
hardened on heating within a few hours and were insoluble to 96-98%.

TITLEs Interfacial polycondensation
PERIODICALs Plasticheskiye massy, np..I, 1961, 10 - 11
TEXTt A study has been made of the acceleration of condensation of epoxy
resin with dephenylol propane (DPP) by interfacial polycondensation,
"sing diphenylol propane (melting pointp 153-1560 C) and commercial 97%
~,qichlorohydrin (EPC). The DPPtEPC ratio was 10.25, 10.5, lt2.3, or 10.
The end of the reaction was ascertained from the DPP content of the aqueous
alkaline solution. The percentage of epoxy groups, Vo at 1&l.25, rose to
2C% at la8. Fig. 2 shows that the optimum concentrations of the sodium
salts of DPP and EPC are obtained in the aqueous and organic phase, re-
spectively. At this concentration, a resin with maximum content of epoxy
groups is obtained. Besides$ the content of epoxy groups depended on the
organia solvent used for the purpose. Solvents in which the forming reCJA
was unsoluble, yielded resins with a lower content of epoxy groups. At an

initial ratio between the components of 10, for example, it was 15-9% for
cyclohexanone and 20.6% for n-butanol. The highest content of epoxy
grouj)B was obtained from n-butanol at any ratio. Polycondensation could
be shortened by thorough mixing and an inorea3e of temperature from 35 to
9000. Mixing, temperature increase, and condensation time had no effect
on the content of epoxy groups. The reaction time of interfacial polyoon-
densation was 15-50 min as compared to a time of 120-360 min required to
perform polycondensation by fusion of the components.

TITLE: Polyamide epoxy resins.-as initial products for
glass-reinforced plastics
PERIODICAL, Plasticheskiye massyt no. 2, 1961, 17 - 22
TEXT: No data have been published as yet on the use of polyamide resins
as binding agents for glass-reinforced plastics because of their poor ad-
hesion to glass. Methylol polyamide resins are distinguished by very high
adhesive power, but glass-reinforced plastics made with them are insuffi-
oiently hard and of low resistance to water. On the basis of the good ad-
hesion of epoxy resins, their stability against water, their hardness and
brittleness, the authors considered it to be convenient to combine these
resins with the high-elastic polyamide resins, and to examine vhether the
resulting polymer can be used as a binding agent. An attempt of obtaining
a homogeneous polymer by mixing solutions of epoxy, polyamide, and methy-

lol polyamide resins was unsuccessful since the mixture did not solidify
on heating. Only by synthesizing the polyamides via the intermediate stem
of methylol polyamides and reacting them with diphenylol propane and epi-
ohlorohydrin it was possible to obtain a grafted polymer. On heating, the
resulting redin passes over into an unmeltable and insoluble state. Con-
densation and hardening of resins were studied in different variations;
the reactions of diphenylol propane with formaldehyde, of epichlorohydrin
with formaldehyde, and of diphenylol propane with methylol polyamide were
investigated. The studies confirmed the assumption of the character of
reaction of these resins. The analysis showed that the following scheme
holds for methylol polyamides resulting from the reaction of formaldehyde
with polyamides via the methylol groups with the epoxy groups of the epoxy
resin and with the methylol groups of the diphenylol propane radical in
the epoxy resin;
